The present invention relates most widely to sleep unconscious body movement information utilization systems and methods, for example, data having new attributes obtained by human sleep unconscious body movement information is existing so-called "Big Data". "By combining with the data that the analysis has been targeting, we can obtain a new space with wide and deep attributes, and by applying the ever-increasing big data analysis method to this, we can confirm the safety of human beings, as well as hospitals and nursing homes for the elderly. , Support for medical care, nursing care and nursing care in general households, fostering new industries, and reducing the social cost of watching over the increasing number of single-person households, especially single-person elderly households, etc. It is suitable for applying to the opposite individual and the whole nation, to maintain and develop sustainably, and to enhance the truly total human social value. Is. More specifically, the present invention relates to, for example, a sleeping situation detection system and method, and is suitable for being applied to, for example, to detect a sleeping situation while a subject goes to bed in a hospital, an elderly care facility, a general household, or the like. It is a thing.
Big data is said to be characterized by three "Vs": volume (volume), variety (diversity), and velocity (velocity) (see, for example, Non-Patent Document 1). ). In recent years, it has been widely recognized that it is valuable to extract information from large amounts of data. It is said that by distributing and analyzing data between different industries, it has become possible to acquire new knowledge, create new businesses in companies, and improve the efficiency of social systems. These are human-origin data, and the total amount of data generated was on the order of being limited by the size of the population, but from now on, sensors will be represented by M2M (Machine-to-Machine) services. And measuring instruments are introduced into society in large quantities, and a large amount of diverse data is generated from them every moment. Therefore, it is necessary to identify an appropriate data source from various data sources (see, for example, Non-Patent Document 1).
The weight ratio of substances that humans ingest in their lifetime is, in descending order, inhaled (83%), drink (8%), and food (7%). "Home air" occupies the largest weight of the inhaled air, and in fact, it accounts for 56% of the total weight of what humans ingest in their lifetime, which has a great impact on their lives. .. In this sense, we need to be more interested in "home air" because living is just the second womb environment (see, for example, Non-Patent Document 2). It is the keratin of the skin and the mucous membranes of the throat and intestines that block the entry of foreign substances into the human body at the forefront, and if not stopped here, neutrophils and macrophages eliminate the foreign substances by phagocytosis. However, clean air is important from the viewpoint of immunity.
On the other hand, conventionally, as a method of detecting the sleeping status of an inpatient in a general ward of a hospital, a resident of a nursing home for the elderly (nursing home for the elderly), or a family member of a general household, and grasping the health condition, the patient is sleeping. There are known methods of photographing hospitalized patients, residents, etc. with a video camera, or attaching a thermometer, a pulse meter, a pulse oximeter, etc. to measure body temperature, pulse, oxygen saturation, and the like. In addition, a system has been developed that uses a sheet-shaped two-dimensional pressure sensor to obtain information when the foot is lowered from the bed to the floor and information on the sleeping posture on the bedding.

<p num="0007"> However, in principle, most of the conventional human-origin data is related to events caused by human decision-making in a conscious state, and a large amount of data from sensors and measuring instruments introduced into society are non-living and It becomes the information data of the machine. There is no doubt that these are useful information, but if data with other attributes is added, it may become an extremely suitable data source for future policies, measures and decision-making. It will increase dramatically.</p><p num="0008"> The IoT (Internet of Things) business requires easy data collection from a wide variety of devices. As a robust and scalable cloud infrastructure is being formed on a global scale, if new attribute (non-contact, non-invasive, unconscious state information) data is combined with the existing data space, it will be a key point in business. , The possibility of discovering opportunities can be maximized. In addition, the effectiveness of existing IT such as data visualization and mining will be significantly improved. Furthermore, it will be possible to enhance the IoT strategy.</p><p num="0009"> In addition, the method of taking a picture of a sleeping inpatient, a resident, etc. with a video camera, or attaching a thermometer, a pulse meter, a pulse oximeter, etc. to measure the body temperature, pulse, oxygen saturation, etc. There is a risk of giving unnecessary stress to residents. In addition, these methods have a drawback in that they cannot be easily performed in ordinary households.</p><p num="0010"> Therefore, the problem to be solved by this invention is, most broadly, recognizing the importance of IT infrastructure required in the cloud and big data era, and in the new era driven by cloud and big data, data attributes. By bringing in new elements, it will bring new innovation and business value, and it will be a solution to the trinity solution related to aging medical care and nursing care cost increase measures, administrative cost increase measures, new industry creation policy. It is to provide a dynamic information utilization system and method.</p><p num="0011"> Another problem to be solved by the present invention is that it is possible to detect the sleeping state of a subject without stressing the subject such as an inpatient or a resident, and to grasp the health condition of the subject from the detection result. It is to provide a sleeping situation detection system and a method which can be performed.</p><p num="0012"> The above and other issues will be clarified by the following description with reference to the accompanying drawings.</p>
<p num="0013"> In order to solve the above problems, the present invention In the room or closed space where the subject sleeps, It has a measuring device installed inside the room or a closed space to measure unconscious body movement information of the subject during sleep in a non-contact and non-invasive manner with respect to the subject. It is a sleep unconscious body movement information utilization system that examines the state of the subject by measuring the unconscious body movement information during sleep with the measuring device while the subject goes to bed.</p><p num="0014"> In the present invention, the subject includes not only humans but also non-human animals. The measuring device preferably includes a dust counter for measuring dust particles inside a room or a closed space. Then, while the subject goes to bed while keeping the inside of the room or the closed space cleaner than the outside of the room or the closed space, the time change of the number of dust particles inside the room or the closed space is measured by this dust counter. Measures unconscious body movement information during sleep. The state of the subject can be examined from the unconscious body movement information during sleep measured in this way.</p><p num="0015"> The sleep unconscious body movement information utilization system according to the present invention can be said to be a system for extracting information on the life activity of a subject in the broadest sense. This sleep unconscious body movement information utilization system is non-invasive and non-contact with the subject, and detects changes that appear as a result of movements of living organisms that include at least some unconscious actions, and determines the detection sensitivity. The above change can be detected by lowering the background instead of raising it. The background is harmful to the subject. Therefore, it is two birds with one stone because it detects useful information at the same time while lowering the background that is harmful to the subject. In particular, the environment surrounding the subject, which provides the environment in which the subject is present and is buried in background noise and cannot be used without this sleep unconscious body movement information utilization system, is changed from the environment surrounding the subject to the subject and the environment. It is possible to extract the information that appears by the interaction, calculate it, and extract the health information, activity information, etc. of the subject. The fact that the subject is human is the main target in terms of medical application.</p><p num="0016"> Typically, the background noise is air dust, or dust particles, and the measuring device, which is an information extraction device, is non-contact and non-invasive to the subject, and the subject is concerned from the environment surrounding the subject. The information that appears due to the interaction between the body and the environment is unconscious body movement information at bedtime, that is, during sleep. In addition, the execution operation is the acquisition of one-dimensional time series data and its correlation analysis. Acquisition of unconscious body movement information during sleep is preferably performed in a clean environment.</p><p num="0017"> In addition, the above-mentioned extracted data becomes a data history for a human being, and the data is used as the human health data to analyze information before being involved in a medical institution, thereby extending the health QOL (Quality of Life). It becomes possible to do. Furthermore, it is expected that the above-mentioned extracted data will be shared among the family members to confirm the safety of remote areas and to recognize and treat common diseases of the family. Furthermore, the above-mentioned extracted data targets local governments, prefectures, and national members of various sizes, confirms the safety of the elderly living alone and citizens living alone, detects when they are in poor physical condition, and urgently dispatches, expresses, etc. Contacting medical institutions will be realized in the future. By suppressing the transition to serious illnesses and serious situations at the water's edge, total costs can be reduced.</p><p num="0018"> A data space targeted by existing big data analysis for data with new attributes that have never been seen before, such as "non-invasive and non-contact measurement data in the unconscious state of a subject" obtained by this sleep unconscious body movement information utilization system. A deep and wide data space can be obtained by combining with (taking a direct product), and extremely useful information can be obtained by performing big data analysis on this data space.</p><p num="0019"> Moreover, this invention Sleep of the subject in a non-contact and non-invasive manner with respect to the subject while the subject sleeps while the inside of the room or closed space in which the subject sleeps is kept clean from the outside of the room or closed space. This is a sleep unconscious body movement information utilization method for examining the state of the subject by measuring the unconscious body movement information at the time.</p><p num="0020"> In the invention of the sleep unconscious body movement information utilization method, as long as the property is not contrary to the property, the above-mentioned invention of the sleep unconscious body movement information utilization system is established.</p><p num="0021"> A typical specific example of the sleep unconscious body movement information utilization system according to the present invention is the sleeping situation detection system described below. The following description also holds true for the invention of the above-mentioned sleep unconscious body movement information utilization system as long as it does not contradict its nature.</p><p num="0022"> That is, the present invention In the room or closed space where the subject sleeps, It has a measuring device installed inside the room or a closed space to measure the environmental information and / or biological information of the subject in a non-contact and non-invasive manner with respect to the subject. It is a sleeping situation detection system that detects the sleeping situation of the subject by measuring the environmental information and / or the biological information by the measuring device while the subject goes to bed.</p><p num="0023"> Here, the environmental information includes, for example, the density of dust particles inside a room or a closed space, temperature, humidity, wind speed (speed and direction of air flow), atmospheric pressure, odor (type of chemical substance that causes odor, and odor. Concentration), type and intensity of sound, brightness (illumination), etc., and biological information is, for example, body movement, heartbeat, pulse, respiration, body temperature and its distribution. Environmental and / or biometric information is typically measured with a time resolution of at least minutes, but is not limited to this.</p><p num="0024"> In this bedtime detection system, the measuring device is typically a dust counter that measures dust particles inside a room or closed space. Then, the subject by measuring the time change of the number of dust particles inside the room or the closed space with a dust counter while the subject goes to bed while keeping the inside of the room or the closed space cleaner than the outside of the room or the closed space. Detects the sleeping situation of.</p><p num="0025"> In this sleeping situation detection system, for example, when the subject unconsciously moves during sleep, for example, when turning over, the number density of dust particles released into the room or the closed space is higher than the rest of the subject. The cleanliness inside the room or closed space is set so that the number density of dust particles corresponding to the ultimate cleanliness of the room or closed space at that time becomes small. Preferably, the interior of the room or closed space is maintained at a cleanliness of US 209D Class 100 or higher. In addition, preferably, the sleeping state of the subject is detected by analyzing the time-varying characteristics of this parameter with respect to the parameter of the number of dust particles inside the room or the closed space. Examples of the time change characteristic analysis include, but are not limited to, autocorrelation function analysis and analysis based on the fast Fourier transform (FFT). For example, machine learning, big data (Big Data) era modeling, data mining and software. When autocorrelation function analysis is used as the time change characteristic analysis, this bedtime detection system calculates the autocorrelation function from the measurement result of the time change of the number of dust particles measured by the dust counter, and obtains the correlation amount. It also has a device. The time variation of the number of dust particles inside a room or closed space is typically measured with a time resolution of at least minutes, but is not limited to this. For example, since the time change of the number of dust particles depends on the timing of measuring the number of particles, it is possible to measure with a time resolution on the order of seconds.</p><p num="0026"> A wall of a room or a closed space, more precisely, at least a part of the partition that separates the outside and the inside of the closed space and defines the space as a closed space, from a film through which dust particles do not pass and gas molecules pass.

A compact space is also possible and permissible for cell culture, tissue formation, and clone growth based on iPS cells and the like. Further, for example, in order to constantly maintain high cleanliness, it is preferable to have at least two closed spaces that can be sealed, and for example, it is composed of two chambers, an anterior chamber and a main chamber. The anterior room is, for example, a room in which humans and the like directly enter and exit from the outside. The main room is provided, for example, in contact with the front room, and is a room in which humans and the like can enter and exit only from the front room.

The important factor in the performance of the conventional clean unit is the particle collection efficiency γ of the filter from the above formula (8), and it is better that this is as close to 1 as possible. This is clear from the fact that, for example, in a general clean unit, a HEPA filter is required from a medium-performance filter, and a ULPA filter is required from a HEPA filter.</p><p num="0071"> In this way, in conventional systems, expensive high-performance filters such as ULPA filters and HEPA filters are used because the filter removal ability directly affects the performance of the clean unit. Since one side of this filter is always in contact with the outside air, the filter becomes clogged. In addition, the higher the performance of the filter, the more likely it is that clogging will occur in a high dust environment, and the air supply efficiency will drop significantly. Therefore, it is generally replaced in about 2 to 3 years. A pre-filter may be provided in front of the filter for the purpose of avoiding this clogging, but the number of filters increases. Increasing the number of filters not only imposes a burden in terms of cost and maintenance, but also increases the pressure loss on the intake side, which causes new problems such as an increase in power consumption.</p><p num="0072"> On the other hand, in this highly clean room system, the particle collection efficiency of the filter is not so dominant, but rather the discharge of dust and dirt inside this highly clean room system becomes more important. The ultimate cleanliness in this highly clean room system is governed only by the internal environment of the room, and according to formula (5), the dust density of the outside air N<sub>0 </sub>As can be seen from the fact that does not appear, it has an extremely preferable property that it is not affected by the installation environment of this highly clean room system at all. This is an advantage that is significantly different from conventional clean rooms and super clean rooms. That is, unlike the conventional super clean room, which has a high construction cost, this highly clean room system can be applied to any place, whether it is a production line, a laboratory, or a general living space, as long as it is an environment that can withstand rain and wind. It will be possible. Further, as can be seen from the mathematical formula (5), a major feature is that there is almost no deterioration in cleanliness even if the dust collection efficiency γ is not close to 1. Therefore, even if an inexpensive filter or a filter with a photocatalytic function is used, good cleanliness can be achieved and high performance can be realized.</p><p num="0073"> FIG. 19 is a schematic diagram showing a change in the number of dust particles in this highly clean room system, using a medium-performance filter (γ = 0.95) as a dust filter. As shown in Fig. 19, the number of dust particles in the room (living space) sharply decreased to less than 100 5 minutes after the start of operation, and the number of dust particles in the room (living space) about 40 minutes after the start of operation. Is less than 10. In this way, the dust filter used in this highly clean room system has a cleanliness even if the dust collection efficiency γ of the 3-nine and 5-nine filters represented by HEPA and ULPA is not as close to 1 as possible. It was shown that there was almost no deterioration.</p><p num="0074"> Now, consider the case where people, etc. are active at the oxygen consumption rate B inside the living space.

From this, it can be seen that A has a certain lower limit to be satisfied as a function of a certain oxygen concentration η to be protected.

As a result, the above constant D can be obtained. For example, the air permeability of the filter cloth, which is an example of a gas exchange membrane, is 3 [l / (dm dm) for a pressure difference of 196 Pa (~ 200 Pa).<sup>2 </sup> Min)] ~ Dozens [l / (dm)<sup>2 </sup> Min)] is known (where l is the unit of volume, liter).</p><p num="0077"> In addition, as a highly breathable membrane, 70 [l / (m) at a pressure difference of 196 Pa.<sup>2 </sup>-S)] membranes have been reported (see, for example, Patent Document 1).

Although the air permeability of the handmade paper also differs depending on the papermaking method, etc., it is considered that it has the same air permeability as above (more strictly, JIS L1096 breathable A method (Frazier type method) and KES. (Measured by an air permeability tester or the like), using the above analytical formula, a film that does not allow gas molecules to pass through, for example, gas exchange, which does not allow dust particles that form at least a part of the internal space adjacent to the living space to pass through. The area of the membrane can be determined according to the equation (16) for the oxygen consumption in the living space and the target oxygen concentration.</p><p num="0078"> In addition, in the conventional clean room, the dust generated inside the clean room is only pushed out and passive, whereas this highly clean room system activates the dust generated inside with a 100% circulation feedback system. By removing it, the cleanliness can be restored in a short time (for example, at most several times the time of V / γF), and the cleanliness of the living space inside the highly clean room can be stably maintained. Therefore, by applying this highly clean room system to general living spaces where the generation of dust is unavoidable in daily life, stable high cleanliness can be obtained inside the living space, and the operating cost is extremely high. Can be a small, highly clean room system.</p><p num="0079"> Here, the filter used in the fan filter unit is a filter in which a photocatalytic function filter is combined with the dust filter, or a plurality of filters are provided by combining the dust filter with a photocatalytic function. It is effective to use a multifunctional filter that also has the above functions.</p><p num="0080"> In realizing the above-mentioned multifunctional filter, paying attention to the gas flow in the feedback gas flow path and arranging a photocatalytic organic matter decomposition mechanism on the upstream side of the dust filter, it is possible to clean while receiving sufficient light irradiation. It is possible to prevent the inflow of the photocatalytic material into the space.</p><p num="0081"> That is, in the case where the above-mentioned feedback gas flow path is provided and all of the outflowing gas is configured to flow into the inlet of the dust filter through the gas flow path (hereinafter referred to as 100% circulation feedback system), the dust is further dusted. By using a multifunctional filter that has both a removal function and a photocatalytic function, the chemical substance concentration can be reduced to the utmost limit. This makes it possible to converge from formula (1) to formula (3) for dust and bacteria, and in formula (3) n is the chemical substance concentration in the gas, σ is the chemical substance generation rate, and γ is. It can be said from the fact that the formula read as the chemical substance decomposition efficiency by the photocatalyst also holds.</p><p num="0082"> On the other hand, when a photocatalytic function is added to a normal system, the outside air is taken in from the external space through a filter and then discharged to the external space, so that the taken-in outside air passes through the filter once or It is limited to a few times at most, and decomposition by the photocatalytic effect of chemical substances etc. can be done only through this limit.</p><p num="0083"> On the other hand, the 100% circulation feedback system described above allows the photocatalytic mechanism to pass through the photocatalytic mechanism many times after the outside air is taken in, which can dramatically improve the decomposition efficiency of chemical substances and the like due to the photocatalytic effect. it can.</p><p num="0084"> In the air purification system provided in the conventional clean room, especially in the air purification system equipped with the dust filter which is always in direct contact with the high dust atmosphere, when the photocatalytic function is simply added to the dust filter, the high dust atmosphere is obtained. The surface of the dust collection filter on the contact side is severely clogged, and the clogging of the dust filter should prevent the photocatalyst from being sufficiently irradiated with light, or the clogging should be decomposed with the photocatalyst material. By hindering contact with a substance, the efficiency of photocatalysis is significantly reduced.</p><p num="0085"> In the above 100% circulation feedback system, the dust filter is installed in a place isolated from the external space, so it does not come into direct contact with the outside air. Furthermore, by incorporating a dust filter into the 100% circulation feedback system, the dust filter can reduce the number of dust by several orders of magnitude due to the circulation equivalent to virtually infinite times, which is a feature of the 100% circulation feedback system. The rate of clogging can be reduced to less than one-thousand to one-10,000th of the conventional one. At the same time, this can solve the problem of deterioration of the decomposition function of the photocatalyst such as chemical substances due to clogging of the filter.</p><p num="0086"> In addition, by utilizing the fact that the dust collection efficiency γ does not necessarily have to be extremely close to 1 as described above, clogging of the dust filter can be avoided by suppressing the value of the dust collection efficiency γ, and functions such as photocatalytic ability can be achieved. Even if the material has a high collection efficiency γ and it is difficult to bring it close to 1, the above circulation feedback system can be used as a dust filter with sufficiently high functionality, so it has high cleanliness and decomposition efficiency of chemical substances, etc. It is possible to achieve both.</p><p num="0087"> By relaxing the condition of the dust collection efficiency γ, it is possible to realize a low dust environment in which the function of decomposing chemical substances by a photocatalyst and the function of removing dust are integrated. Examples of the photocatalyst include titanium oxide, platinum, palladium and the like. Examples of the photocatalyst filter include a paper filter carrying the above-mentioned photocatalyst, a resin filter carrying a photocatalyst, a porous photocatalyst ceramic filter made of tungsten oxide, and the like. Specific examples thereof include a high-density filter made of a non-woven fabric (containing polyester, modal acrylic, etc.) impregnated with a photocatalytic material such as titania or tungsten oxide. Further, the porous photocatalytic ceramic filter can simultaneously realize a low harmful substance environment by the photocatalyst and an ultra-clean environment by the dust filter. In this way, it is not necessary to take the conventional tandem arrangement of HEPA and photocatalyst filter, so that the system can be made compact and the pressure loss due to the filter can be suppressed to a small level, which is very efficient. By reducing the load of the blast power, it can also contribute to energy saving.</p><p num="0088"> Compared to the case where a photocatalyst is simply used for a wall, etc., this system actively passes the gas in a closed space through a filter that has both a dust removal function and a photocatalyst function, so that the decomposition efficiency of pollutants in the gas is high. Will increase dramatically. Further, by adding a photocatalytic function to the surface of the dust filter, bacteria and dust captured by the dust filter can be decomposed into carbon dioxide and water. These make it unnecessary to clean and replace the dust filter, and it becomes the ultimate system that can be used as a dust filter that can be used semi-permanently. In particular, with this highly clean room system, a sterile, dust-free, non-hazardous gas environment can be realized anywhere, for example, in the middle of the city, so in this room, fragrant trees and trees By placing plants such as herbs, it is possible to realize a forest bath and an air environment of a plateau rich in nature while staying at home. Furthermore, it is possible to bring out a relaxation effect by positively introducing an aroma scent. As a result, it is possible to realize an environment that contributes to the relief and healing of asthma symptoms.</p><p num="0089"> As this multifunctional filter, a photocatalytic function filter is added to the dust filter and combined, or the dust filter is provided with a photocatalytic function to provide a plurality of functions to one filter. It is preferable to have them together. When a photocatalytic function filter is combined with the dust filter, for example, it is preferable that the photocatalyst function filter is provided in series with the dust filter in the gas flow path. Further, the multifunctional filter can be composed only of a photocatalyst, for example, a TiO composed of a porous body.<sub>2 </sub>May be configured as a multifunctional filter. In realizing this multifunctional filter, pay attention to the gas flow in the feedback gas flow path, and while shining sufficient light on the photocatalyst provided in the multifunctional filter, the inflow of the photocatalyst material into the clean space It is preferably configured to prevent it. Specifically, for example, by arranging a photocatalyst function filter on the upstream side of the dust filter, it is possible to prevent the inflow of the photocatalyst material into the clean space while exhibiting the decomposition function of organic matter by receiving sufficient light irradiation. it can.</p><p num="0090"> Further, a local exhaust device having a gas exchange function for exhausting the inside air of the living space may be provided in the room or the tent-like structure. The configuration of the local exhaust device is basically not limited, but for example, the direction of the air flow inside the local exhaust device is such that the inside air and the outside air of the living space share the traveling direction. Furthermore, inside the local exhaust system, gas molecules that do not pass through at least one dust fine particle are brought into contact with each other through a film that allows them to pass through, thereby increasing the concentration of molecules that make up the inside air of the living space. The concentration of the molecules that make up the outside air approaches an equilibrium state through the concentration diffusion of the molecules through the membrane that does not allow the gas molecules to pass through, and then the inside air of the living space returns to the living space. It is preferable that it is. The local exhaust system configured as described above is suitable for alleviating offensive odors and removing harmful odors in a hospital room or a nursing room, for example, and in an air at a painting factory or the like while keeping the dust density extremely small. It is possible to reduce the concentration of the organic solvent in the above.</p><p num="0091"> It is also possible to combine a heat pump type air conditioner provided with a heat exchanger in the feedback gas flow path. Further, by providing, for example, an ion-releasing air purifier in this highly clean room system, the effect of eradicating viruses and the like by ions such as OH radicals can be dramatically enhanced. This is because, in the past, when this air purifier was installed in an environment exposed to the outside air with extremely low cleanliness, the generated ions were taken in by large dust, and the effect of decomposing small dust, viruses, etc. by the ions was maximized. I couldn't show it. On the other hand, in this highly clean room system, the size of the dust present is extremely small and the amount is extremely small, and new dust is not supplied from the outside air into this highly clean room system. The effect of decomposing small dust, viruses, etc. can be maximized. In addition, it is possible to significantly extend the life of the filter provided in the ion-releasing air purifier.</p>

Alternatively, since the sleeping condition of the subject is detected by measuring the biological information, the sleeping condition can be detected without giving stress to the subject, and thus the health condition of the subject can be grasped. In particular, when the sleeping condition of a subject is detected by measuring the time change of the number of dust particles inside a room or a closed space with a non-contact and non-invasive dust counter while the subject goes to bed. , The sleeping situation can be detected without giving stress to the subject, and the health state of the subject can be grasped based on, for example, the frequency of turning over.</p><p num="0094"> In addition, when the above-mentioned highly clean room system or building is used as a room or a closed space in which the subject sleeps, the following effects can be obtained.

In addition, for example, 10 hours after running this system and switching it on, the US 209D Class 1 can be realized. In addition, there is no problem of pressure difference between the pressure of one room of a house or a house and the other part of the house caused by using the conventional clean room technology, and the cleanliness of the room is improved. be able to. In addition, by actively collecting the dust generated inside by the fan filter unit attached to the room, "the generated dust is scattered to the outside of the room and causes trouble to the people living outside the room.

It is possible to provide a highly clean room system that can always maintain the above-mentioned high air purification performance and can live and work comfortably and comfortably. As mentioned above, the steady-state dust particle density of a conventional clean room depends on the dust particle density No. of the environment, and for this reason, a high-quality filter with a dust collection efficiency γ as close to 1 as possible was required.

Hereinafter, embodiments for carrying out the invention (hereinafter referred to as embodiments) will be described.
<1. First Embodiment> [Sleeping status detection system] FIG. 1 shows a sleeping situation detection system according to the first embodiment. As shown in FIG. 1, in this sleeping situation detection system, a bed 202 is placed on the floor of a room or a closed space 201, and a subject 203 can sleep in a supine or lying position on the bed 202. There is. Inside the room or closed space 201, there is no inflow and outflow of air as an air flow between the inside and the outside, and inside the room or closed space 201, there is an opening that takes in the inside air of this room or closed space 201 (FIG. (Not shown) and an outlet (not shown) for returning the entire amount of the suction air to the inside of the room or the closed space 201 after the cleaning treatment are provided as a pair. In this example, this is achieved by a fan filter unit 208 installed on the floor, but the cleaning treatment site itself can also be provided outside the room or closed space 201. Further, as already described, the room or the closed space 201 is composed of a wall or a partition (which defines the space as a closed space by separating the outside and the inside of the closed space), and at least a part thereof is dust fine particles. Gas molecules can be composed of a membrane that does not pass through but does pass through. When the room or the closed space 201 is composed of a wall, the wall is preferably a wall for a room having an internal space into which outside air can be introduced, and communicates the outside and the internal space with the end face of the wall. A wall having a vent, at least one of the main surfaces forming the interior space is impervious to dust particles and has a membrane through which gas molecules pass. Preferably, the wall is in contact with the interior of the room or closed space via the membrane, but is not shown here for the sake of simplicity while avoiding complexity. In order to provide the same gas exchange capacity, the gas exchange device shown in FIGS. 35 to 38 described later may be used. Pillow 204 is placed on bed 202. For example, a comforter 205 is hung on the subject 203. The dust counter 206 is installed at a position different from the position where the bed 202 is placed in the room or the closed space 201. With this dust counter 206, it is possible to measure the number density of dust particles inside a room or a closed space 201. .. It has become possible to send the dust fine particle number density n (t) as a function of time t measured by the dust counter 206 to the computer 207 installed outside the room or the closed space 201 by wire or wirelessly. There is. For example, the dust counter 206 and the computer 207 are connected by a LAN. Then, the arithmetic unit of the computer 207 can perform time change characteristic analysis based on the measured n (t), for example, analysis based on the autocorrelation function analysis and the fast Fourier transform. In this case, for example, using a mobile phone, information may be aggregated for analysis and data management by a computer installed at a Hypnokinetogram analysis and a corresponding service base, which will be described later, by wireless communication. The Hypnokinetogram analysis and response service base may be in the same building such as a nurse center in a hospital or nursing home, or in a certain remote location like an existing centralized management base for security services. May be good. The result of the time change characteristic analysis can be displayed on a display connected to the computer 207, and can be printed by a printer connected to the computer 207 as needed, and connected to the storage device of the computer 207 or the computer 207. It can be saved in the external storage device. Further, although not shown, a fan filter unit may be installed on the ceiling of the room or the closed space 201, and the inside of the room or the closed space 201 may be cleaned by operating the fan filter unit. Preferably, the cleanliness of the interior of the room or closed space 201 is greater than the number density of dust particles released into the room or closed space 201, for example, when the subject moves, eg, rolls over. The number density of dust particles corresponding to the ultimate cleanliness of the subject's resting room or closed space 201 is set to be small. Specifically, for example, the cleanliness of the interior of a room or closed space 201 is US 209D. Maintain cleanliness of class 100 or higher. By maintaining a high degree of cleanliness inside the room or the closed space 201 in this way, background noise due to residual dust particles can be significantly suppressed, and it is generated by a change in body position due to the subject turning over. The change in the number density of dust particles can be clearly extracted.
[How to use the sleeping status detection system] How to use this sleeping situation detection system will be described.
First, the inside of the room or the closed space 201 is maintained at a predetermined cleanliness by operating the fan filter unit 208 or the fan filter unit installed on the ceiling of the room or the closed space 201. The dust counter 206 is always operated. In this state, the subject lies on the bed 202 in the supine or lying position, the head is placed on the pillow 204, and the comforter 205 is hung. Then, the lights of the room or the closed space 201 are turned off, and the person goes to bed. While sleeping, the dust counter 206 measures the dust fine particle number density n (t) inside the room or the closed space 201. Dust is generated when the subject changes his / her body position by turning over or peeling off the comforter 205 while sleeping, which causes a change in the dust fine particle number density n (t). That is, the dust fine particle number density n (t) reflects the behavior of the sleeping subject, in other words, the body movement, and this body movement reflects the health condition of the subject. Therefore, the health condition of the subject can be grasped by analyzing the time-varying characteristics of the dust fine particle number density n (t).
If necessary, while the subject is sleeping, all of them are contact measurements, but the distribution of the pressure applied to the bed 202 according to the subject's weight is measured, the body temperature is measured by a thermometer or black body radiation spectrum analysis by the body temperature, and the pulse meter is used. Perform at least one of pulse measurement, oxygen saturation measurement with a pulse oximeter, etc., and use the measurement results together with the results and data of the time change characteristic analysis of the dust fine particle number density n (t), and correlate distribution. , Multidimensional analysis such as correlation analysis may be performed to grasp the health condition of the subject. By doing so, it is possible to take a direct product of the set of measurement data by non-contact measurement and the set of measurement data by contact measurement, which was not possible in the past based on this information related to the health condition of the subject. It is possible to perform higher-order analysis, to grasp the health condition more accurately, and to predict the transition of the health condition in the future. Therefore, it is possible to take measures based on them. Since it is a response before the onset of the pathological condition, it is expected that it will be possible to control medical expenses and practice preventive medicine. In particular, as shown in Fig. 2A, the non-contact measurement data in this unconscious state is combined with the data space of conventional big data analysis as shown in Fig. 2B to form a new data space to be the target of big data analysis. By using it, it is possible to analyze from an unprecedented aspect. That is, in big data analysis, it is important to create a model that determines the idea and skeleton of analysis, but by combining data in the unconscious state of human beings, it is extended to modeling that includes a potential decision-making mechanism. By combining this with existing POS (Point of Sale) and IoT information, it is expected that new modeling of new purchasing motivation and purchasing activities will be possible.
The room or closed space 201 is not particularly limited as long as it can be maintained in a highly clean environment, but is, for example, a room of a general detached house or a room of an apartment house such as an apartment.
As described above, according to the sleeping situation detection system according to the first embodiment, the density of dust particles during bedtime of the subject is measured while the inside of the room or the closed space 201 is maintained with high cleanliness. As a result, the sleeping condition of the subject can be easily detected, and the density of dust particles can be measured by the dust counter 206 in a non-contact and non-invasive manner to the subject without giving unnecessary stress to the subject. I'm done. Since the sleeping state of the subject can be easily detected in this way, the health state of the subject can be grasped based on the detection result. Specifically, for example, when the frequency of turning over is extremely high, the dust fine particle number density and the correlation amount frequently increase or decrease, but at this time, the subject's health condition is not excellent, and conversely, the dust fine particle number density and the correlation amount. Subjects tend to be in good health when the amount changes slowly. If the number density of dust particles and the amount of correlation increase or decrease frequently, it is possible that the subject's normal breathing is impaired during sleep for some reason, and various respiratory disorders and sleep apnea syndrome are suspected. Be told.
<2. Second embodiment> In the sleeping situation detection system according to the second embodiment, it is different from the first embodiment that the room of the new highly clean room system is used as the room or the closed space 201, and the other things are the first embodiment. Similar to form.
First, the new walls used in this highly clean room system will be described.

Side walls 9c to 9f are provided so as to block all four surfaces. Further, a rectangular parallelepiped is formed by joining the walls 9a to 9f without a gap, and an internal space (hollow portion) of 9 g is formed inside the rectangular parallelepiped. The inner wall 9a is provided in contact with the living space of room 1, which is a closed space. By forming this wall 9 with, for example, a high-strength material, it contains 9 g of an internal space (hollow portion) into which outside air can be introduced while being a robust structure as a whole. Vents 11 are provided at both ends of the side wall 9d forming the wall 9. In this case, the vent 11 provided at the upper end of the side wall 9d is an outside air inlet (inlet), and the vent 11 provided at the lower end is an exhaust port (outlet). Further, at least a part of the inner wall 9a is composed of the gas exchange membrane 26. Further, in the internal space 9g, a C-shaped cross-section steel 15a is provided so as to be sandwiched between the inner wall 9a and the outer wall 9b so as to face each other at a constant distance from the side wall 9c, and to have a constant distance from the side wall 9d. H-shaped cross-section steel 15b is provided so as to be placed so as to face each other. Further, the C-shaped cross-section steel 15a and the H-shaped cross-section steel 15b are provided parallel to the side wall 9c and the side wall 9d. The C-type cross-section steel 15a and the H-type cross-section steel 15b are preferably provided so as to be in contact with the end of the gas exchange membrane 26, for example, and by providing them in this way, sufficient strength to support the room 1 is ensured. can do. Further, a brace 16 is provided between the C-shaped cross-section steel 15a and the side wall 9c so as to connect the upper end of the side wall 9c and the lower end of the C-shaped cross-section steel 15a. Further, a brace 16 is also provided between the H-shaped cross-section steel 15b and the side wall 9b so as to connect the upper end portion of the side wall 9b and the lower end portion of the H-shaped cross-section steel 15b. As a result, sufficient strength can be secured to support the room 1. In addition, C-shaped cross-section steel 15a and Of the members constituting the pillar material of the H-shaped cross-section steel 15b, holes 15c are provided on the surface of the members in the direction orthogonal to the gas exchange membrane 26, and the gas is configured to flow freely through the holes 15c. There is. By constructing the wall 9 in this way, air can be exchanged between the internal space 9g, which is the internal space of the wall 9, and the open space of the house such as the corridor 33 adjacent to the side wall 9d, through the vent 11. To do. This air exchange is preferably provided at the lower end of the side wall 9d by forcibly introducing outside air (fresh air) from the vent 11 provided at the upper end of the side wall 9d by, for example, mechanical ventilation. Exhaust this from the vent 11. A gas exchange film 26 is provided on the inner wall 9a in contact with the living space of the room 1, so that the air inside the room 1 and the gas in the internal space 9g are not exchanged as an air flow. Separated. Although there is no direct exchange of airflow mass flow between the living space of room 1 and the internal space of 9 g, gas molecules (oxygen, nitrogen, carbon dioxide, etc.) that make up the air and ammonia that is emitted with human life and activities, etc. When there is a difference in concentration on both sides of the gas exchange film 26, the trace chemical substance of the above causes concentration diffusion, and by exchanging the molecule through the gas exchange film 26, the chamber in contact with the wall 9 1 The internal air can be maintained in an environment suitable for people to live and work. Further, the gas exchange film 26 can be replaced with a two-dimensional structure obtained by weaving the gas exchange film. As the member constituting the outer wall 9b of the wall 9 that supports the structure of the room 1, for example, it is preferable to use a high-strength material which is a plate material having sufficient thickness and strength, and a material to which heat insulation and soundproofing functions are added is used. Is more preferable. With this configuration, the wall 9 as a whole is guaranteed to function as a structure with high heat insulation and sound insulation performance. On the other hand, in the wall 9 shown in FIG. 3B, two vents 11 are provided on the side wall 9e which is the upper side wall. Other than that, it has the same structure as the wall 9 shown in FIG. 3A. By constructing the wall 9 in this way, the house such as the attic that is in contact with the internal space 9g and the wall 9e
Here, consider the area of the gas exchange membrane 26 provided on the inner wall 9a. Assuming that the area of the gas exchange film 26 (or two-dimensional structure) is A, the volume of the living space of room 1 which is a closed space is V, the oxygen consumption rate inside the living space of room 1 is B, and the state of equilibrium with the outside world. The oxygen volume when there is no oxygen consumption inside the living space of room 1 is V<sub>O2</sub>, When the oxygen diffusion constant of the gas exchange membrane 26 (or two-dimensional structure) is D and the target oxygen concentration in the living space is η (η> 0.18), the gas exchange membrane 26 (or two-dimensional structure) Area A of (body) is at least<maths num="16"><img id="000026" he="19" wi="159" file="JP5877459B2_D0001.tif" img-format="tif" img-content="drawing" /></maths>The gas exchange membrane 26 is set so as to satisfy the above conditions. When the gas exchange film 26 is replaced with, for example, a two-dimensional structure, the two-dimensional structure is a folded structure such as a ninety-nine fold (a structure having a plurality of curved surfaces and / or planes). If the structure is stretched and unfolded, the two-dimensional area is defined as the area A. As a result, the oxygen concentration in the room 1 in contact with the wall 9 can be kept above the target value of η.
As described above, the wall 9 is provided so that the outer wall 9b and the inner wall 9a face each other at a certain distance, and the side walls 9c to 9f are provided so as to close the opening surface thereof, and at least a part of the inner wall 9a. Is composed of a gas exchange membrane 26. By constructing these walls with a high-strength material, etc., the structure is a robust structure as a whole, but contains 9 g of an internal space (hollow part) that can introduce outside air. can do. Further, by providing the inner wall 9a of the wall 9 so as to be in contact with the room 1 forming the living space which is a closed space, the wall 9 as a whole is a structure having sufficient strength, heat insulation and sound cutoff performance. It is possible to exchange gas molecules between the living space of the room 1 and the internal space 9g of the wall 9 without directly exchanging the air flow mass flow, while ensuring the function as. That is, when gas molecules (oxygen, nitrogen, carbon dioxide, etc.) constituting the air and trace chemical substances such as ammonia emitted with human life and activities have concentration differences on both sides of the space partitioned by the gas exchange membrane 26. In addition, concentration diffusion occurs and the molecules are exchanged through the gas exchange membrane 26 to maintain the air inside the room 1 in contact with the wall 9 in an environment suitable for people to live and work. can do.

Further, in FIG. 3C, the broken line indicates the walls such as the partition wall and the ceiling wall provided inside the room 1a, and the internal configurations of the other rooms 1a are shown by solid lines.
Room 1a has a rectangular parallelepiped shape and is the outermost structure in the highly clean room system 10 and forms a closed space. It has a living space 6 and an attic 5 as subspaces constituting this closed space. The attic 5 is an internal space formed by a double ceiling. This double ceiling is composed of a top surface of the room 1a and a ceiling wall 2a provided so as to face each other at a certain distance from the top surface. That is, the living space 6 and the attic 5 are separated by the ceiling wall 2a. Of the side walls constituting the living space 6, the wall 9 on the right side in the drawing has the same configuration as the wall 9 shown in the first embodiment, and is shown in the first embodiment. It contains an internal space 7 having the same structure as the internal space 9g of the wall 9. Specifically, a wall 9 containing an internal space 7 is formed by a double wall composed of an outer wall 9b and an inner wall 9a provided in parallel with each other at regular intervals. The side walls 9c to 9f constituting the wall 9 shown in FIG. 3A are composed of the side walls 2e, the side walls 2c, the ceiling wall 2a, and the floor wall 2g constituting the room 1a. A gas flow path 24 is provided in the internal space 7, and an opening 23 is provided in at least a part of the inner wall 9a. This opening 23 corresponds to the suction port of the fan filter unit 21 installed on the surface of the ceiling wall 2a on the attic 5 side. For example, a plurality of openings 23 may be provided. Specifically, the thickness of the internal space 7, that is, the distance between the inner wall 9a and the outer wall 9b, is preferably, for example, 5 cm or more and 40 cm or less, and more preferably 10 cm or more and 20 cm or less. A gas exchange membrane 26 is stretched on the inner wall 9a of the wall 9 that separates the living space 6 and the inner space 7. The gas exchange membrane 26 is configured so that gas molecules do not pass through the dust fine particles, and constitutes a part of the inner wall 9a which is a partition wall between the living space 6 and the internal space 7. For the gas exchange membrane 26, if the living space 6 is, for example, Japanese-style or Japanese-style room, it is preferable to use shoji paper. A wall structure that does not allow dust particles to pass through but allows gas molecules to pass through is, for example, on the inner wall 9a. It is obtained by providing an opening for communicating the living space 6 and the internal space 7, and then attaching the gas exchange membrane 26 so as to completely close the opening. Further, the gas exchange film 26 can also be a two-dimensional structure obtained by weaving the gas exchange film. Further, it is preferable that the directions of the air flowing in the living space 6 and the interior space 7 separated by the inner wall 9a of the wall 9 are the same, and the flow speeds are also the same. Is preferable. As for this configuration, for example, it is preferable to provide a blower in the living space 6. With this configuration, gas exchange by the gas exchange membrane 26 can be smoothly performed. Further, in the living space 6, the side walls 2b and 2e forming the left back corner of the room 1a, the side walls 19a and 19b provided on the side walls facing each other, and the ceiling wall 2a are closed. It has a utility space 19 which is a space. This utility space 19 is used, for example, for a toilet, a bath, a wash basin, and the like.
The ceiling wall 2a of the portion where the fan filter unit 21 is provided is provided with an opening corresponding to the outlet of the fan filter unit 21, and this opening and the outlet of the fan filter unit 21 have airtightness. The outlet 22 is formed by being connected. The outlet 22 and the outlet of the fan / filter unit 21 are airtightly integrated. Clean gas is supplied to the living space 6 by emitting airflow from the outlet of the fan / filter unit 21. The fan / filter unit 21 can also be installed inside the interior space 7 of the wall 9.
In the internal space 7 formed in the wall 9, the opening 23 and the fan filter unit are retracted from the surface of the gas exchange membrane 26 by about half the thickness of the wall 9, for example, 5 cm or more and 10 cm or less. A gas flow path 24 that airtightly communicates with the gas inlet to 21 is provided. As a result, it is possible to secure a volume on both sides of the gas exchange membrane 26 that allows the presence of sufficient gas. The gas flow path 24 has, for example, a duct structure having a thickness of 5 cm or more and 15 cm or less and a width of about 90 cm. The opening 23 is a suction port for introducing the air inside the living space 6 into the gas flow path 24. The entire amount of the gas entering through the opening 23 passes through the gas flow path 24 and returns to the suction port of the fan filter unit 21. In this way, a 100% circular feedback system is completed. The internal space 7 can be effectively used by providing the internal space 7 of one wall 9 with two functions of gas exchange capacity and storage of the gas flow path constituting the 100% circulation feedback system. The fan filter unit 21 may generally be located anywhere in the 100% return path attached to the living space 6, and may be stored not only in the ceiling arrangement described above but also in a floor-standing form inside the wall 9, for example. You can also. In this way, as is clear from the situation shown in FIG. 3C, it is possible to construct an extremely clean room system without making the room smaller than that of a conventional residential room.
The attic 5 and the internal space 7 are configured to communicate with each other by providing an opening in the ceiling wall 2a constituting the internal space 7. A vent 11a is provided on the side wall 2e in contact with the attic 5. The side wall 2e in contact with the living space 6 of the room 1a has an entrance 8 through which a human can enter and exit the living space 6 and the external space. For example, between the corridor (not shown) and the living space 6. You can come and go freely. Further, a vent 11b is provided on the side wall 2c in contact with the internal space 7. The vents 11a and 11b serve as inlets and outlets for introducing outside air. For example, the fresh air flowing in from the vent 11a is introduced into the internal space 7 of the wall 9 of the room 1a via the ceiling 5. Carbon dioxide generated in the living space 6 and the like through the gas exchange membrane 26 is concentrated on the internal space 7 side, and oxygen is concentrated on the living space 6 side where oxygen is consumed from the internal space 7 of the wall 9. It is diffused and thus gas exchange occurs. The air after the gas exchange is discharged from the vent 11b. Similarly, the gas and chemical molecule generated in the room are also discharged to the outside through the internal space 7 of the wall 9. The role of the inlet and outlet of the vent 11a and the vent 11b can also be reversed by the ventilation mechanism of the entire building. That is, it is also possible to introduce fresh air from the outside via the vent 11b and discharge dirty air to the upper outside via the vent 11a. Further, when a plurality of vents 11a are provided, the combination of the inlet and the outlet can be appropriately selected, and the vents 11b can also be appropriately selected. In addition, by not providing an opening in the ceiling wall 2a, it is possible to configure the ceiling wall 5 and the internal space 7 so as not to communicate with each other. In that case, the ventilation holes 11a and the ventilation holes 11b are completely independent. Can be.
Gas molecules are exchanged between the internal space 7 in the wall 9 and the living space 6 via the gas exchange membrane 26 regardless of the presence or absence of communication between the attic 5 and the internal space 7. That is, oxygen, carbon dioxide, or chemical substance molecules that cause a living odor are diffused by a concentration gradient according to the concentration difference between the inside and outside separated by the gas exchange membrane 26, and the air inside the living space 6 is used for living and living. It can be kept suitable for the activity. When using a flat shoji paper-like two-dimensional film (shoji paper), the area of the gas exchange film 26 is, for example, 135 cm × 135 cm. Air is supplied to the living space 6 by blowing air downward from the outlet 22 of the fan / filter unit 21. While pushing the dust in the air in the living space 6 downward, the opening 23 and the suction port of the fan filter unit 21 are separated from the opening 23 provided at the lower part of the inner wall 9a of the wall 9 forming the internal space 7. It flows into the gas flow path 24 that communicates with airtightness, and the entire amount returns to the fan / filter unit 21 through the gas flow path 24. In this way, a 100% circulation flow path is completed by configuring all the gas flowing out from the fan filter unit 21 into the living space 6 to return to the fan filter unit 21. Further, as described above, by configuring at least one of the side walls of the room 1a with the wall 9 shown in the second embodiment, the internal space 7 contained in the wall 9 is gas exchanged and 100%. It can be provided with both functions of storing the gas flow path constituting the circulation feedback system. As a result, the space inside room 1a can be effectively used, and compared to a conventional residential room, it is extremely natural as a room with a shoji-like design that fits into the side of the room without making the room smaller. A highly clean environment can be realized. By installing a lighting fixture behind the shoji-like gas exchange film 26 provided on the side wall, it is possible to play the role of indirect lighting in which the wall itself shines. In this case, the wall 9 is highly functional with three roles per person. Acts as a wall.
Further, when it is desired to decompose not only dust but also odors and the like, the photocatalyst 61 may be provided in the gas flow path 24. The photocatalyst 61 may be, for example, a combination of a photocatalyst and a dust filter in addition to the photocatalyst alone. The photocatalyst 61 is provided, for example, inside the gas flow path 24, and in this embodiment, for example, the photocatalyst 61 is provided in series with the fan filter upstream of the dust filter of the fan filter unit 21. It is not limited. Since this photocatalyst 61 operates in an almost dust-free state under this highly clean room system, it is freed from the problem of clogging, and it is possible to operate exclusively for the original photocatalyst function, and the photocatalyst function is available. It will be maintained for a very long time. It can be said that the photocatalyst device is extremely compatible with the 100% circulation system of the present invention, like the commonly used functional devices such as Plasmacluster (registered trademark) and Nanoe (registered trademark).
According to this second embodiment, in addition to the same advantages as those of the first embodiment, the following advantages can be obtained. That is, since at least one of the side walls of the room 1a is composed of the wall 9, one internal space can be provided with both functions of gas exchange and storage of the gas flow path constituting the 100% circulation feedback system. , Room 1a The space inside can be effectively used, and the core part of the high-cleaning system can be embedded without making it smaller than the room of a conventional house. Further, since it is necessary to provide only one 100% return path, there is an advantage that a highly clean room system can be easily assembled at low cost. It can be a suitable system when the frequency of entering and exiting the room 1a is low and the time spent in the living space 6 is relatively long.
More specifically, this bedtime detection system using a highly clean room system can provide various advantages such as the following. That is, the elderly population, single-person living and single-living population ratios in Japan are steadily increasing (see Non-Patent Document 5). According to the Ministry of Health, Labor and Welfare's 2035 estimate, more than 40% of elderly households and 18.45 million people live alone. In addition, the aging rate in Japan is expected to rise further, and countermeasures are an urgent issue. In the awareness survey on the aging society, the percentage of those who answered that they live alone is high, and even when they are strongly anxious about living alone and their physical strength is weakened, "I want to continue living in the place where I am accustomed to living". Many people "want to move into a shared rental housing for the elderly who can receive living support", but it is not easy medically, financially, and administratively to respond to this. Elderly care facility (long-term care welfare facility for the elderly) that supports the super-aging society that will be welcomed in the future The environment of rooms such as hospitals and hospitals is not yet sufficient, such as problems of cleanliness and odors, and sometimes problems of infectious diseases occur. There is no clean technology that can be applied to general hospital rooms of elderly care facilities or rooms of ordinary houses, and even in the wards of general hospitals, there is no support except for some negative pressure rooms for isolation. The current situation. The conventional clean room technology is applied to semiconductor manufacturing, etc. by keeping the inside under positive pressure, and for medical use by keeping the room under negative pressure so that bacteria and viruses do not go out. Attempting to solve the PM2.5 problem and the problem of infection by such conventional technology is practically impossible because the actual living environment is narrowed and the cost is too high. It is thought that elderly people still often live in rooms with relatively difficult clean environments such as "tatami mats," "futons," and "Japanese-style rooms," and the application of clean technology that can handle these is extremely important. According to this sleeping situation detection system using a new highly clean room system, the potential of a highly clean environment will be blossomed, and while responding to the needs of the elderly and singles, we will prepare for the future aging society and Japan. It is possible to establish elemental technologies for (1) curbing medical expenses for the elderly, (2) fostering growth industries, and (3) reducing the burden on the administration of the elderly. Since the highly clean room system can be easily realized by renovating the room of a normal ordinary household, this sleeping situation detection system can be easily realized even in an ordinary household. That is, it has been demonstrated that even a room in a general house can have a cleanliness higher than, for example, a super clean room for manufacturing LSI. For example, remote computer control of particle number measurement by the dust counter 206 using a LAN cable has already been realized, and it becomes possible to detect the sleeping situation based on the time-varying characteristic analysis of the dust fine particle density in a dust-free and sterile environment. In addition, with a highly clean room system equipped with a 100% circulation feedback system, PM2. Not only can the 5 problems and pollinosis problems be solved, but it is also possible to measure the above-mentioned bedtime turnover spectrum and grasp the health condition. As described above, according to the sleeping condition detection system using the highly clean room system, it can be applied to hospitals, nursing homes for the elderly, and private houses to provide a low-cost and stable high-clean environment, and the sleeping condition detection enables super-aging. It will be possible to realize simple health management that corresponds to society. That is, a highly clean room system that uses a shoji screen or the like as a gas exchange membrane is a system that can realize a highly clean environment while dressed in a pure Japanese style, and is suitable for a person to go to bed inside. In other words, the highly clean room system makes it possible to create a clean space of US 209D class 100 class (cleanliness equivalent to a dust-free room or operating room in a hospital) while staying in a general house, thereby going to bed as it is (1). 0. per cubic foot. Compared to the case of sleeping for about 7 hours while the total amount of dust of 5 μm or more is about 100,000), the intake of dust into the lungs can be suppressed to about one-thousandth, and the respiratory system is affected every night. It will be a good refreshment. By suppressing the background of dust in this way, information on turning over (size and frequency), which was not available in the past, can be easily obtained in a non-invasive, non-contact method and at home for the first time in history. (Spike-like signals in FIGS. 47 to 55 described later). This is unconscious body movement information during sleep (and information in reproducing a truly normal life and sleep state because a probe etc. is not attached to the body), so it is a Hypnokinetogram. We were able to create a new useful measurement technology and a data analysis system. In the medical and long-term care fields, by applying Hypnokinetogram data, which is time-series data of sleep state (unconscious) body movements, to an expanded data space that includes as a subspace, we can maintain health and move from a non-diseased state to a healthy state. You can make a return. In addition, by combining the data space with this new attribute with the data space targeted by existing big data analysis, activity information in the human conscious state and a huge amount of data space (human [] conscious state [] ] Reflection: Data space by (, ) and IoT (Data space of consciousness [] by inorganic substances and non-living bodies []: This can be written as (, )) And, the Hypnokinegram information space (human origin [], but the reflection of the unconscious state []: this can be written as (, )), but (, ) (, ) ( It can be combined with the configuration of , ), and it is possible to deepen and expand the data in big data analysis. This new data space will be a support for changing the way of medical care for the better, even in the recent trend of mobile health that changes the way of clinical practice. () and the data space by IoT (data space of consciousness [] by inorganic substances and non-living organisms []: this can be written as (, )) are hyponokinegram information space ( Human origin [], but reflection of unconscious state []: This can be written as (, )), but they are combined in the composition of (, ) (, ) (, ) This makes it possible to deepen and spread data in big data analysis. This new data space will be a support for changing the way of medical care for the better, even in the recent trend of mobile health that changes the way of clinical practice. () and the data space by IoT (data space of consciousness [] by inorganic substances and non-living organisms []: this can be written as (, )) are hyponokinegram information space ( Human origin [], but reflection of unconscious state []: This can be written as (, )), but they are combined in the composition of (, ) (, ) (, ) This makes it possible to deepen and spread data in big data analysis. This new data space will be a support for changing the way of medical care for the better, even in the recent trend of mobile health that changes the way of clinical practice.
As a result, the safety of the sleeping person can be remotely monitored while protecting privacy because video information such as video is not used, which can be a major pillar of the serviced long-term care business. Furthermore, higher-order information obtained from the bit string (change in the number of dusts over time) Therefore, the information on turning over of the sleeping person is accumulated (acquisition of body movement information as big data), and based on this, the depth of sleep, shallowness, health information, etc. are not connected to the body at all. It can be extracted in an extremely natural state (obtaining a biological signal in an unconscious state provides highly objective data). The application goes beyond correlation in individuals. For example, by sharing data with each other, families living far away can virtually "live together" as if they were "living under one roof." Furthermore, by expanding this to local governments, data will be accumulated from the stage of being a healthy person who does not need long-term care before becoming ill for single-living people, especially the elderly living alone, and the QOL will be maintained high. It is expected to contribute to doing so. Ultimately, it is expected that it will be possible to curb medical expenses and reduce the burden on the administration for the elderly. Although the views of short-term exposure to PM2.5 are limited in domestic and foreign studies, the relationship with a wide range of health effects such as cardiac and cardiovascular functional changes and respiratory symptoms has been investigated, and these risks Introducing a clean environment that can significantly reduce the risk to general households as well as hospitals and schools, and highly sensitive people ( It is also possible to protect people with respiratory and circulatory diseases, children, the elderly, etc.). In other words, we will realize a "tent", room and house system that grasps the health condition and gives various advice like a full-time family doctor. Just sleeping in the room of the highly clean room system not only reduces the load on the respiratory organs to almost zero for about 7 hours (it emerges by setting the background noise to zero), but also the size and frequency of turning over. In addition to confirming the safety of the sleeping person (user), it is possible to check for deviations from the normal state, depth of sleep, and signs of illness. In the event of an abnormality, the goal of connecting the hospital and home as it is and reducing the risk of sudden illness for consumers is the living space itself (living environment compatible with long-term care medical care). Highly clean room system (environment) and remote monitor (information communication), a new frontier of living that had no means of realization It will be possible to realize by combining. PM2. It is one of the air pollutants and easily penetrates deep into the lungs, and there are concerns about its effects on the circulatory system in addition to its effects on the respiratory system. 5 Particles are reduced to almost zero (see Fig. 10, Fig. 11 and Fig. 59A), and health by autocorrelation function analysis of turning information big data and bedtime dust time change, which is possible for the first time with this sleeping situation detection system. It is also expected to become the cornerstone of a new form of Japanese society, such as management, pre-illness care, individual and family data accumulation, and virtual integration of singles by sharing health information between nuclear families. In addition, according to the high-clean room system, it is possible to significantly reduce the odor, which has been a problem in elderly care facilities, by exchanging gas. In addition, by using a tent-type high-cleaning system as shown in FIGS. 46A and 46B described later in place of the high-cleaning room system, highly sensitive persons (persons with respiratory or circulatory system diseases, children, elderly people) It will be possible to realize the well-being of people) not only in hospitals and nursing homes for the elderly, but also in rooms of ordinary households. In this case, the area around the bedding is covered like an ancient Japanese mosquito net at bedtime to achieve high cleanliness. In particular, even when sleeping inside (at rest), US 209D class 100 grade cleanliness can be achieved. According to an awareness survey on the aging society, when asked how to live when the anxiety of living alone becomes stronger or the body becomes weaker, "I want to continue living in the place where I am accustomed to living" and "Life support". People's desire to move into a "communal rental housing for the elderly" is remarkable, so to meet these needs, a high-clean environment realized by a high-clean room system and a tent-type high-clean system and turning over at bedtime Examples include autocorrelation analysis, FFT conversion, big data compatible data mining and software. When autocorrelation function analysis is used as the time change characteristic analysis, it is fully possible to respond by enabling remote care at low cost based on this sleeping situation. This clean environment can protect highly sensitive persons (persons with respiratory and circulatory system diseases, children, elderly people, etc.) not only in hospitals, elderly care facilities and schools, but also in general households. PM2. 5 Establishing defensive measures will lead to prevention of second-hand smoke, measures against pollinosis and measures against airborne infectious diseases due to sidestream smoking during smoking, so it will be possible to maintain and improve the health of Japan, where the ratio of the elderly population will increase in the future. It will be developed as an unsung hero, and it will be possible to control medical expenses for the elderly and create industry and vitality at the same time. It will be possible to support the health and safety of single-person households, which is estimated to reach about 20 million people in 2035, with remote monitors, and to help people's well-being and health maintenance.
In addition, for example, the lung is an organ that is particularly prone to allergic reactions because it is exposed to a large amount of substances (antigens) that cause allergic reactions such as dust, pollen, fungi, and chemical substances floating in the air. It is often said that exposure to irritating dust and substances in the air during work may increase the possibility of respiratory allergic reactions, but in the clean space of the present invention, one day It is possible to improve this by spending about 7 to 8 hours of our sleep with almost no load on the respiratory tract. In addition, in patients with chronic obstructive pulmonary disease, clusters called iBALT formed by densely packed immune cells are usually seen. This iBALT is said to promote a rapid immune response to inhaled allergens and particles such as soot and tobacco smoke, and may persist chronic lung inflammation and cause tissue damage. The formation of a closed space by a curtain-like structure made of a gas exchange film using the curtain rail or the like of the clean space of the present invention is performed in a medical institution hospital room (multi-person room) by a curtain that "blinds" from the surroundings. It is expected to be a gospel for patients with chronic obstructive pulmonary disease because it can be introduced at a high price-to-performance ratio with almost no change in the current situation. Hypersensitivity pneumonitis (extrinsic allergic alveoliitis) is a type of inflammation that occurs inside or around the small air sacs (alveoli) and the narrowest airways (alveoli) in the lungs, such as organic dust. Although it is infrequent, it is a disease caused by an allergic reaction caused by inhaling chemical substances, but it is said that if it is not exposed again, it will usually recover, so US in general home and office environments Rather than waiting for recovery in hundreds of thousands of dust in the 209D class, lay bedding such as a futon in the clean closed space of the tent-like structure of the present invention, and wake up in the US 209D class 100-1000, which is 1000 times cleaner. By doing so, it is expected that a recovery that will be several steps faster will be obtained. In addition, allergic bronchopulmonary aspergillus disease is an allergic reaction of the lungs to a type of fungus (most commonly Aspergillus fumigatus), which can occur in patients with asthma and cystic fibrosis. Since Aspergillus is found everywhere in the living environment, it is difficult to avoid contact with this fungus, but bedding such as futons or curtain rails can be moved in the tent-type clean closed space of the present invention. By placing bedding such as a bed in a closed space on the gas exchange membrane and going to bed in it, the average of 7 to 8 hours of sleep in a day is one-hundredth to one-thousandth of the contact. It is possible to: and it is expected that contact with this fungus can be reduced to a nearly negligible amount during that time.
<3. Third embodiment> FIG. 4 shows the highly clean room system 10 used in the sleeping situation detection system according to the third embodiment. This sleeping situation detection system is different from the first embodiment in that the room of the new highly clean room system 10 is used as the room or the closed space 201, and the other things are the same as those in the first embodiment.
As shown in FIG. 4, this highly clean room system 10 has room 1b on the left side of the drawing and room R on the right side of the adjacent rooms.<sub>2 </sub>Is provided. In this figure, the room R represented by the alternate long and short dash line<sub>2 </sub>Is a virtual room, and the configuration is not limited as long as it has a configuration independent of room 1b. Further, in the figure, the broken line portion indicates a wall such as a partition wall and a ceiling wall provided inside the room 1b, and the internal configuration of the other room 1b is shown by a solid line.
Regarding the high-clean room system, there may be an increasing need for higher performance than the high-clean room system shown in the second embodiment. For example, it may be applied to immunodeficiency treatment in hospitals, more complete prevention of infectious diseases in nursing homes for the elderly, home medical treatment in general households, and the like. At this time, for example, it is necessary to devise a device that does not deteriorate the cleanliness of this space even at the moment of entering and exiting between the living space 6 which is a hospital room or a nursing room and the outdoors or a corridor. For that purpose, while utilizing the configuration of the room 1a of the second embodiment, an additional configuration is introduced.
That is, in the room 1b, the side wall facing the wall 9 which is the side wall constituting the room 1a shown in the second embodiment is a wall 13 including an internal space 12 configured in the same manner as the wall 9. Is. That is, among the side walls constituting the room 1b, all of the side walls facing each other on the side not having the doorway 8 are composed of the wall 9 and the wall 13 including the internal space, and the internal space contained in the wall 9. 7 and the internal space 12 contained in the wall 13 are independent of each other. Further, the structure of the wall 13 and the internal space 12 can be the same as that of the wall 9 and the internal space 7. In room 1b, the wall on the left side of the figure is composed of a wall 13 having the same configuration as the wall 9 shown in the second embodiment, and this wall 13 is composed of an outer wall 13b and an inner wall 13a. Has been done. The wall 13 has an internal space 12 which is a second internal space, and this internal space 12 is a space adjacent to the living space 6 via the gas exchange membrane 26. Specifically, the thickness of the internal space 12 is preferably, for example, 5 cm or more and 40 cm or less, and more preferably 10 cm or more and 20 cm or less. As will be described later, since the gas flow path 24 does not have to be stored inside the internal space 12, the thickness of the internal space 12 can be as thin as 15 cm or less.
The gas flow path 24 provided inside the internal space 7 may be provided on the inner wall 9a. This is because a part of the inner wall 9a is not composed of the gas exchange membrane 26. Further, the wall 9 and the wall 13 can use the wall itself as a gas flow path. However, when the wall itself is used as a return path, the vent 11b provided on the wall 9 is closed. Further, the thickness of the gas flow path 24 is preferably 5 cm or more and 10 cm or less as described above, but the thickness of the gas flow path 24 is increased to the thickness of the internal space 7 to improve the cross-sectional flow rate. You can also increase the conductance of. A part of the inner wall 13a of the wall 13 is composed of a gas exchange membrane 26.
Further, the attic 5, the internal space 7 and the internal space 12 formed by the double wall may or may not communicate with each other via the attic 5. Further, either one of the internal space 7 and the internal space 12 may communicate with the ceiling 5. The introduction of the outside air into the internal spaces 7 and 12 can be performed in the same manner as in the second embodiment, and the combination of the inlet and the outlet of the vents 11a and 11b can be appropriately selected depending on the application. For example, in room 1b, two vents 11a provided on the side wall 2e in contact with the ceiling 5 are paired with an in and an out, but as described above, for example, the vents 11a are both in and the out is It is also possible to carry it on the vent 11b at the bottom of the side wall.
The anterior chamber 40, which is a subspace of the living space 6, is formed by providing a partition so as to face the doorway 8. Specifically, the sliding door 47 closes the opening surface of the space surrounded by the side wall 2e of the room 1b having the doorway 8, the inner wall 13a of the wall 13, the partition wall 19b of the utility space 19, and the ceiling wall 2a. It is composed of being provided. This sliding door 47 functions as a partition. Further, the sliding door 47 may have a configuration provided in a part of a partition wall provided so as to close the opening surface. In addition, the space other than the front room 40 of the living space 6 constitutes the main room 20. That is, the sliding door 47 has a function of partitioning the front chamber 40 and the main chamber 20. When opening the sliding door 47, it is set to open along the side wall 19a constituting the utility space 19, and the sliding door 47 is arranged so as not to generate an unnecessary dead space when the sliding door 47 is opened and closed. When the sliding door 47 opens, the front room 40 and the main room 20 communicate with each other, but by closing the sliding door 47, the front room 40 and the main room 20 are completely separated. Further, it is preferable that at least a part of the main surface of the sliding door 47 is composed of the gas exchange membrane 26. As the gas exchange film 26, for example, by selecting shoji paper or a filter cloth or non-woven fabric filter material like shoji paper, it is possible to impart gas exchange ability to the sliding door 47 while bringing out the taste of the traditional Japanese Shoin-zukuri style. When the gas exchange membrane 26 is provided in the sliding door 47, specifically, for example, the sliding door 47 is provided with an opening in which both the front and back surfaces communicate with each other, and the gas exchange membrane 26 is stretched so as to completely close the opening. With this configuration, gas exchange can be performed between the inside and the outside of the anterior chamber 40 even if there is no inflow and outflow as an air flow between the inside and the outside of the anterior chamber 40.
The wall on the left side of the figure forming the anterior chamber 40 is composed of the wall 13. A gas exchange membrane 26 is stretched on the inner wall 13a that separates the anterior chamber 40 and the internal space 12 of the wall 13, and the gas exchange membrane 26 constitutes a part of the inner wall 13a. Further, in the internal space 12, in parallel with the gas exchange membrane 26, a distance of about half the distance between the inner wall 13a and the outer wall 13b, that is, a distance of 5 cm or more and 20 cm or less is set back from the membrane, and the gas flow path 43 is stored. The gas flow path 43 airtightly communicates between the opening 46 provided at the lowermost portion of the inner wall 13a and the gas inlet of the fan / filter unit 44 provided on the ceiling wall 2a inside the ceiling 5. doing. The fan filter unit 44 is connected to the outlet 45 so that gas is sent out into the front chamber 40. The outlet 45 is configured in the same manner as the outlet 22. The gas flow path 43 can be configured in the same manner as the gas flow path 24. For example, in addition to using a duct having a rectangular cross section, a plurality of bellows pipes may be connected in parallel. The gas flow path 43 is airtightly connected to the opening 46. The air inside the anterior chamber 40 is introduced into the gas flow path 43 through the opening 46, and the entire amount of the air returns from the outlet 45 to the inside of the anterior chamber 40 again.
Further, as a simpler type, the gas exchange membrane 26 provided on the inner wall 13a inside the anterior chamber 40 can be omitted and replaced by the function of the gas exchange membrane 26 (shoji paper) constituting the sliding door 47. .. The gas flow path 43 need only be configured inside the internal space 12 so as to be isolated from the internal space 12, and can be realized, for example, simply by connecting with the bellows pipe described above. Further, in this embodiment, in order to impart gas exchange capability as much as possible, at least a part of the ceiling wall 2a constituting the main room 20 and at least a part of the ceiling wall 2a constituting the utility space 19 are also gas exchange membranes 26. However, the presence or absence of the gas exchange membrane 26, the area to be installed, and the like can be appropriately designed and selected according to the amount of oxygen and the like used inside the room.
Next, the operation of the highly clean room system 10 will be described. A person who enters from an external space such as a corridor through the doorway 8 once waits for several tens of seconds to several minutes in the front room 40, then opens the sliding door 47 and enters the main room 20. By doing so, it is possible to enter without deteriorating the cleanliness of the living space. On the other hand, even when human beings leave, the cleanliness of the main room 20 is completely deteriorated by entering the front room 40 from the main room 20, closing the sliding door 47, and then going out from the doorway 8 to the outside. You can go out to the corridor or outdoors without letting it go. Others are the same as in the first and second embodiments.
<Example of high-clean room system> This highly clean room system can be used not only for newly built buildings such as houses and buildings, but also for remodeling existing buildings. In this embodiment, the mechanism of the high-clean room system is incorporated into the room of a general house to obtain the high-clean room system 10.
FIG. 5 is a top view showing the room before incorporating the mechanism of the highly clean room system.
As shown in FIG. 5, room 1 is 3600 mm square and has a rectangular parallelepiped shape with a height of about 2300 mm. In addition, an entrance / exit 8 is provided at a portion of the side wall facing the corridor (not shown) of the room 1 in contact with one corner. At the other corner, a rectangular parallelepiped storage section 19c with a width of 1800 mm, a depth of 900 mm, and a height of 2300 mm is formed in the room 1. If this space is regarded as a corner corresponding to the utility space 19 of the third embodiment shown above, this embodiment is a mode in which a highly clean environment system is applied to a newly built house or the like. Performance equivalent to that of the third embodiment can be implemented in a mode in which a room such as a house that already exists in general is remodeled and a highly clean environment system is applied. That is, the room 1 can be regarded as having a utility space 19 called a storage unit 19c in one corner of the room 1 having the doorway 8, and is regarded as a space equivalent to the room 1a shown in the second embodiment, for example. Can be done. Then, by remodeling this room, the configuration of the high-clean room system 10 is given, and the performance equivalent to that of the high-clean room system described in the third embodiment is already exhibited in a very ordinary house. It can be applied to rooms such as. Here, the internal configuration of room 1 will be described. A window portion 54 having a width of 1690 mm and a height of 1170 mm is provided on the side surface of the room 1 facing the side surface where the doorway 8 is provided. The living space 6, which is a space other than the storage unit 19c in the room 1, is composed of two rectangular parallelepiped spaces of different sizes connected to each other. Of these two rectangular parallelepiped spaces, one is surrounded by the side wall 19b of the storage portion 19c, the portion of the side wall 2b facing the side wall 19b, and the part of the side wall 2c sandwiched between the side wall 19b and the side wall 2b. It is a rectangular parallelepiped space, which is a space immediately after entering the living space 6 from the doorway 8. The specific dimensions of this rectangular parallelepiped space are depth x width x height = 900 mm x 1800 mm x 2300 mm. In addition, this rectangular parallelepiped space will be converted into the anterior chamber 4 after the renovation described below. It constitutes 0 and the internal space 57. The other is a rectangular parallelepiped space surrounded by the side wall 19a of the side wall 2e and the storage portion 19c, the portion of the side wall 2d sandwiched between the side wall 2e and the side wall 19a, and the part of the side wall 2b facing the side wall 2d. It is the space on the window side of room 1. The specific dimensions of this rectangular parallelepiped space are depth x width x height = 2700 mm x 3600 mm x 2300 mm. This rectangular parallelepiped space constitutes the main room 20 and the internal space 12 after the renovation described below.
FIG. 6 is a top view showing Room 1 after incorporating the mechanism of the highly clean room system. Further, FIG. 7 is a cross-sectional view (perspective view) seen from the side wall 2b side. FIG. 8 is a cross-sectional view (perspective view) seen from the side wall 2c side.
As shown in FIGS. 6 to 8, a living space 6 is formed inside the room 1. After the renovation, the above two rectangular parallelepiped spaces are partitioned by a partition 41 and a sliding door 47, so that the living space 6 has a space having a main room 20 and an internal space 7, and a front room 40 and an internal space 57. It is divided into space. Further, the storage portion 50 of the fan filter unit 21 is provided with a panel parallel to the ceiling wall 27 of the room 1, and the space formed by the ceiling wall 27 and the panel is airtightly surrounded by the fan filter. A fan / filter unit storage unit 50 in which the unit 21 and the gas flow path 24 are housed is formed. In addition, by installing the wall 9a in parallel at a distance of about 15 cm from the side wall (conventional wall) 2d, the wall 9 becomes a hollow wall in which the side wall (conventional wall) 2d and the inner wall 9a are integrated. .. The wall 9 preferably has the wall configuration shown in the second embodiment. Since the thickness of the side wall 2d is about 10 cm and the thickness of the inner wall 9a is about 0.6 cm, the total thickness of the wall 9 which is a double wall having an internal space is about 26 cm. Further, according to the above configuration, the thickness of the internal space 7 which is the hollow space of the new wall 9 is 15 cm. Further, it is surrounded by the side wall 2b, the side wall (conventional wall) 2c having the doorway 8, the side wall (conventional wall) 19b of the room 1 facing the side wall (conventional wall) 2b, the partition 41, and the sliding door 47. The space is divided into an anterior chamber 40 and an internal space 57 by being partitioned by a partition wall 56. The partition wall 56 is provided so as to block between the end of the side wall 2c on the door 8 side and the partition 41 so as to face the side wall (conventional wall) 19b. The front room 40 is the space that a person first enters when entering room 1 from the external space. On the other hand, the internal space 57 is a space for storing the 100% circulation feedback flow path in the anterior chamber 40.
The sliding door 47 is provided so as to slide on the surface of the partition 41, and when the sliding door 47 is closed, the spaces forming the main chamber 20 and the anterior chamber 40 are completely separated from each other. Further, when the sliding door 47 is opened, the sliding door 47 slides to move to a position on the main surface of the partition 41 of the main room 20. Further, the sliding door 47 is configured so that the front chamber 40 maintains airtightness when the sliding door 47 is closed. Further, it is desirable that the partition 41 and the sliding door 47 are provided on the same plane as the side wall 19a so that the main room 20 has as little unevenness as possible because the dead space is reduced and the living performance is improved. When both the doorway 8 and the sliding door 47 are closed, the anterior chamber 40 is in a closed state with no dust particles entering or exiting. You can enter room 1 from the outside by opening the doorway 8. A fan filter unit 44 is provided on the ceiling wall 2a in the attic 5. In the front chamber 40, an opening 46 corresponding to the suction port of the fan filter unit 44 is provided at the bottom of the wall 56, and all the gas flowing out from the outlet 45 of the fan filter unit 44 into the front chamber 40. Is 100% circulated by passing through the opening 46 and returning to the fan filter unit 44 through the gas flow path 43 that airtightly communicates between the suction port of the fan filter unit 44 and the opening 46. A feedback system is configured.
As described above, the inner wall 9a is provided parallel to the side wall 2d of the room 1 at regular intervals, and the wall 9 contains a space 7 in contact with the main room 20 via the gas exchange membrane 26. The wall 9 has an airflow inlet and an outlet on its end face, and the internal space 7 and the corridor which is the external space are connected by pipes 55a and 55b. In this way, the gas can be exchanged between the external space and the internal space 7, so that the internal space 7 functions as an outside air introduction space. The pipe 55a is an inlet pipe having an inlet 11c, and the pipe 55b is an outlet pipe having an outlet 11d. Its outer diameter is 10 cm. Further, it is desirable to provide, for example, a mechanical ventilation device at the suction port 11c and / or the discharge port 11d. Specifically, for example, the mechanical ventilation device preferably has an air volume generation capacity such that the air in the main chamber 20 makes one rotation or more in two hours. One rotation in 2 hours means that all the air in the main room 20 is ventilated in 2 hours. At least a part of the inner wall 9a is composed of shoji paper which is a gas exchange membrane 26. As a result, the main room 20 becomes a closed space surrounded by a side wall including a general wall material or a gas exchange film 26, and there is no air flow in and out between the internal space 7 and the external space. , Gas molecules can be exchanged between the main chamber 20 and the internal space 7 communicating with the outside. As a result, when there is a concentration difference in the gas components constituting the air between the main room 20 and the internal space 7 communicating with the outside, the internal space 7 and the main room 20 are connected to each other via the gas exchange film 26. Gas molecules that make up the gas and various molecules contained in the air of the room that accompany life and work inside the room are diffused between the two, and the constituent gas components of the air in the main room 20 Moves so that its concentration reaches equilibrium with that of the outside. That is, if the oxygen concentration in the main chamber 20 decreases, oxygen is supplied from the internal space 7 through the gas exchange membrane 26, and if the carbon dioxide concentration in the main chamber 20 increases, the gas exchange membrane 26 from the internal space 7 Carbon dioxide is emitted through. Also, in the main room 20
Further, a 100% circulation feedback system composed of a fan / filter unit 21 and an airtight gas flow path 24 is connected to the main chamber 20. The inner wall 9a that separates the main chamber 20 and the internal space 7 is provided with an opening 23 that is a suction port that constitutes a 100% circulation feedback system. The gas sucked from the opening 23 enters the suction port of the fan filter unit 21 through the gas flow path 24 that airtightly communicates between the opening 23 and the fan filter unit 21, and inside the gas flow path 24. After being filtered, it is pushed out (exhausted) to the main room 20 through the outlet 22, and this air takes in the dust inside the room and returns to the opening 23 again to form a 100% circulation feedback system. .. The gas flow path 24 is a bellows pipe having a diameter of about 10 cm in this embodiment. Moreover, although this embodiment shown in FIGS. 6 to 8 is not drawn by strictly scaling the dimensions and distances only to show the concept, the gas flow path 24 is about from the gas exchange membrane 26. It recedes 5 cm and is almost in contact with the wall 2d. Further, by forming at least a part of the inner wall 9a that separates the main room 20 and the internal space 7 with shoji paper, which is an example of the gas exchange membrane 26, the inner wall 9a betweens the internal space 7 and the main room 20. The gas can be exchanged with.
In addition, when there is an entrance / exit between the external space and the front room 40 by the doorway 8, the inside of the front room 40 is cleaned with both the doorway 8 and the sliding door 47 closed. Specifically, after the anterior chamber 40 is closed, the 100% circulation feedback system using the fan / filter unit 44 described above is operated. Further, as shown in FIGS. 22 and 26, which will be described later, the cleanliness of the anterior chamber 40 is remarkably improved 40 and several tens of seconds to several minutes after the operation of the fan filter unit 44. You can enter the main room 20 from the front room 40. Further, by forming at least a part of the sliding door 47 with a film having a gas exchange ability such as shoji paper, the above-mentioned gas gas component is formed even if there is no air flow in and out between the main chamber 20 and the front chamber 40. Can be exchanged.
FIG. 9 is a photograph taken by a digital still camera showing the completed appearance of the highly clean room system 10 according to this embodiment.
As shown in FIG. 9, the wall 9 which is the back wall is the wall 9 shown in this embodiment, and is a photograph of the inside of the main room 20 of the room 1 in which the wall 9 is incorporated as one of the side walls. .. The room 1 having the window portion 54 is provided with a fan filter unit 21 and a gas flow path 24 stored in the storage portion 50 on the ceiling portion, and clean air is discharged downward from the outlet 22. The wall 9 has an inner wall 9a that separates the main room 20 from the internal space 7, and the fan / filter unit storage portion 50 extends and contacts the wall 9a. A part of the inner wall 9a is a gas exchange film 26 having an area of 135 cm × 135 cm, and is composed of shoji paper which is the gas exchange film 26. Further, an opening 23, which is a suction port, is provided at the lower end of the wall 9a. A net is provided in the opening 23 to prevent large dust from entering the gas flow path 24.
The order estimation of the shoji paper area is based on the following considerations. The shoji paper used as the gas exchange membrane 26 is a commercially available consumer and general-purpose product (plain shoji paper manufactured by Asahipen Corporation), and physical property values such as air permeability are not presented. Therefore, the air permeability of the shoji paper used is a conservatively estimated value [~ 1l / (dm) among the typical values of the air permeability of the filter cloth already mentioned.<sup>2 </sup> Min)]: The shape, size, etc. of the shoji paper used as having 200 Pa) were designed, and the area was determined. As will be described later, since a person actually enters the main room 20 and conducts an experiment, it is preferable to estimate the air permeability conservatively and set the area A large from the viewpoint of safety. Because. Further, the second term of the mathematical formula (12) shown above is the volume F occupied by the oxygen molecules diffused through the gas exchange membrane per unit time (the unit is, for example, [m].<sup>3 </sup>/ min]) is shown, so consider this as a function of pressure (partial pressure) difference from the formula as a function of concentration difference, and the above-mentioned air permeability is the pressure per unit time and unit area. Considering that it is the volume occupied by the gas molecules diffused in the difference, the D / L of the gas exchange film appearing in the equation (12) shown above can be calculated from the air permeability. When the target oxygen concentration η = 20.8% is set from the viewpoint of safety, the condition to be satisfied for the area A of the gas exchange membrane 26 is<maths num="17"><img id="000027" he="28" wi="158" file="JP5877459B2_D0001.tif" img-format="tif" img-content="drawing" /></maths>Will be. In addition, as shown in the midway derivation formula of formula (17), D / L corresponds to the pre-coefficient of the denominator in the same formula, and is calculated to be about 5 [m / min] based on the above air permeability value. ..
Further, as shown in the photograph, by using the gas exchange membrane 26 as a shoji window formed in a grid pattern with a wooden frame, the inside of the main chamber 20 can be made extremely clean, but the main chamber 20 is mainly cleaned. You can create a Japanese-style atmosphere in room 20. Further, a gas flow path 24 that airtightly communicates with the gas inlet of the fan / filter unit 21 is connected to the opening 23 provided at the lowermost portion of the inner wall 9a, and the flow path is inside the internal space 7. Is running. As described above, the highly clean room system 10 can achieve extremely high cleanliness at the same time with a Japanese-style appearance without any discomfort as compared with the conventional room space.
The configuration for connecting the main room 20 and the front room 40 as shown above is not limited to the above example, and examples thereof include traditional Japanese-style rooms and Japanese-style inn rooms. The room of a traditional Japanese-style inn has a so-called stepping (shoe and clogs removal space) that is separated from the back room (main room 20) by shoji screens when entering the entrance. The above configuration of the anterior chamber 40 can be introduced in this space. Taking off your shoes is exactly the wisdom of ancient Japan that does not bring dust into the main room 20 in the back, but by adding the cleaning technology of the present invention to this, the Japanese-style room is one of the best in the world in both name and reality. It is possible to point out the cleanliness with a world-class appearance and put it to practical use without losing the traditional appearance at all. In addition, in the case of a traditional Japanese residence, the outside can be used as the outside air introduction source to the inside space 7, the Sanwa soil space can be used as the front room 40, and the back room can be used as the main room 20. .. In the case of modern Japanese rooms (rooms such as condominiums), the outside is used as the outside air introduction source to the inside space 7, and the entrance space (shoes and clogs are taken off) is used as the front room 40. The room can be the main room 20. In addition, in the case of Western-style single-family homes, the corridor and the outside are used as the outside air introduction source to the interior space 7, which is the outside air introduction space, and a new entrance space (shoes and clogs is taken off) is provided in the Japanese style, and the front room. By setting 40 and the remaining room space as the main room 20, measures such as pollinosis can be taken.
Next, the operation of the highly clean room system 10 according to this embodiment will be described. First, a change in air cleanliness in the main room 20 when the fan / filter unit 21 provided in the main room 20 is operated independently will be described.
FIG. 10 is a schematic diagram showing the time change of the number of dust particles in a short time scale when the fan filter unit 21 constituting the 100% circulation feedback system provided in the main chamber 20 is operated. 11 is a schematic diagram showing the same time change on a long time scale.
As shown in FIGS. 10 and 11, at the start of operation of the fan filter unit 21, the total amount of dust having a particle size of 0.5 μm or more exceeds 100,000 / cubic foot (US 209D class 100,000), 0.3 μm. The sum of the above dust is an environment with an extremely large number of dust particles, which is far from clean, exceeding 1 million per cubic foot. After the operation of the fan / filter unit 21 started, the number of dust particles in the main chamber 20 decreased to about 1000 in about 5 minutes from the start of operation, and after 10 minutes, 100 particles per cubic foot. Below, ie, US 209D Good cleanliness of class 100 or higher. Furthermore, as shown in FIG. 11, it is shown that, not only the total amount of dust having a particle size of 0.5 μm or more but also the total amount of dust having a particle size of 0.3 μm or more shows 0 count after about 10 hours from the start of operation. Was done. Here, since the vertical axis of the schematic diagram shown in FIG. 11 is a logarithmic plot, the measured value zero cannot be plotted (because the vertical axis flies to infinity downward). Therefore, for convenience, here, the zero count obtained in the measurement is plotted at 0.01 for convenience. The particle size means the average particle size of the primary particles (the same applies hereinafter). This result is US As a cleanliness that is comparable to the cleanliness of a 209D class 1 class super clean room used in high-quality semiconductor factories, etc., and can be achieved in a room with an ordinary home-like appearance as shown in this example. Is the world's first, and is considered to be extremely significant in that it has both a visual affinity in the daily living environment and an ultra-clean environment.
Next, a case where oxygen is consumed by a person staying in the main room 20 will be described. FIG. 12 is a drawing-substituting photograph showing an experiment in which oxygen is consumed in the main room 20. As shown in FIG. 12, by burning butane gas with a cassette stove in the main room 20 and further allowing two people to stay in the main room 20, oxygen in the main room 20 is consumed while consuming oxygen in the room. The concentration was measured.
Figure 13A shows butane (C) from the start of this experiment to 80 minutes.<sub>4 </sub>H<sub>10</sub>) It is a schematic diagram showing the amount of gas burned and the oxygen concentration in the main chamber 20. FIG. 13B is a schematic diagram showing the change in oxygen concentration in the graph of FIG. 13A enlarged at around 20%.
<chemistry num="1"><img id="000028" he="12" wi="158" file="JP5877459B2_D0001.tif" img-format="tif" img-content="drawing" /></chemistry>
From the chemical reaction formula (1), considering that 1 mol of butane is 58 g and oxygen is 32 g, when butane gas is burned at 2 g per minute, the oxygen consumption is about 5 [l / min. ] It turns out that. This is equivalent to the oxygen consumption of about 20 humans. The number of people is too large to fit in the living space of about 6 tatami mats, which is the size of room 1 used in this embodiment, which is a sufficient amount to see the oxygen supply capacity. The gas stove used for this measurement was placed in the center of the room, but removed from directly below the fan / filter unit. In addition, the oxygen concentration meter used for this measurement was placed at the position of the wall facing the gas exchange membrane, and therefore at the position farthest from the gas exchange membrane.
In addition, as shown in FIGS. 13A and 13B, the oxygen concentration in the main chamber 20 decreases by about 0.3% from 20 minutes to 60 minutes, temporarily reaches 20.6%, and then starts to increase. This is in good agreement with the numerical value of 20.8%, which is the target oxygen concentration in the formula (16) shown above. The temporary drop in oxygen concentration to 20.6% is an expected undershoot, which can be explained as follows. Due to the balance between the position of the gas stove and the position of the oxygen concentration meter, the analysis by mathematical formulas (9) to (15) is simple, so there is no location dependence of the concentration. That is, it is natural that the oxygen concentration has a spatial distribution, but due to the effect of the ventilation power of the fan / filter unit installed on the ceiling, "the air in the room is stirred sufficiently quickly, and the oxygen concentration becomes It is solved by the approximation that "there is no unevenness in location". Therefore, this undershoot is expected, and the point at which it started to increase after that is considered to be 20.8%, and the agreement between the calculation and the experimental result is considered to be quite good. As described above, when the oxygen concentration in the main chamber 20 has a concentration difference between the living space and the internal space 7 of the wall 9 communicating with the outside world, the concentration diffusion of oxygen molecules occurs in the direction of eliminating this. As a result, it is shown that the oxygen concentration can be achieved to be close to 20.9% based on the mathematical formula (15) shown above, despite the large amount of oxygen consumption inside the main chamber 20. Was done. Even if 22 humans stay for a long time, oxygen will not be deficient in the main room 20 in contact with the wall 9 having shoji paper, which is the material of the 135 cm × 135 cm square gas exchange membrane 26. This is because the barrier paper, which is the gas exchange membrane 26 that separates the main chamber 20 and the internal space 7 of the wall 9, exchanges various molecular concentration components between the outside air introduced into the internal space 7 and the gas of the main chamber 20. It is shown that it functions well as a membrane that balances on both sides of the membrane 26.
In addition, the D / L can be calculated from the above-mentioned experimental result that the oxygen concentration in the main chamber 20 starts to decrease and stops decreasing about 40 minutes later. That is, the equation (12), which is a differential equation describing the change in the oxygen concentration of this system, has the same form as the differential equation of the equation (3), and the exact solution has the same form as the equation (4). (Especially as time dependence, they are equal and show an exponential change with respect to t. In more detail, if γF / V in equation (4) is replaced with AD / VL in equation (12), Well, you can grasp the temporal behavior of the system). As already mentioned, the exponential behavior settles down after about 10 times the reciprocal of the coefficient of time t on the shoulder of the exponential function. From this, it can be set to {1 / (AD / VL)} × 10 to 40 min based on the result of FIG. 13B. A = 1.35m x 1.35m = 1.8m<sup>2 </sup>Also, from Fig. 6, the area is about 6 tatami mats and the ceiling height is about 2.5 m, so the volume of the main room 20 is V = 24 m.<sup>3 </sup>Because it is, D / L ~ (24m<sup>3 </sup>/1.8m<sup>2 </sup>) 10 (1/40 min) ~ 3.3 m / min, which is in good agreement with the D / L ~ 5 m / min obtained in connection with the determination of the shoji paper area described above. That is, in a system that employs a 100% circulation feedback system in a wall 9 that has a membrane that does not allow dust particles to pass through and allows molecular concentration diffusion and an internal space that is in contact with it, and a room that is in contact with this wall, an oxygen consumption experiment (gas) inside By conducting a combustion experiment), D / L, which is an important parameter of the film, can be obtained. Once this value is found, in this highly clean room system, equation (12) holds with a good approximation, and the parameter that characterizes this system is VL / AD, so this VL / AD is {(V). By rewriting as / A) / (D / L)}, the design of the room in contact with this gas exchange membrane (V) is based on the parameter D / L, which is determined only by the properties of the gas exchange membrane 26, according to the scaling. It can be seen that it presents a new method for setting A and A, etc.) with extremely good visibility. In other words, the ratio of the depth of the room, or "effective aspect ratio", V / A related to gas exchange, to the abstract aspect ratio D / L in the "functional space" of gas exchange is taken (when dimensional analysis is performed). , (V / A) / (D / L) is m<sup>3 </sup>/ m<sup>2 </sup>Molecules with the dimension of, m<sup>2 </sup>/ (m / s) Divided by the denominator with the dimension of). When the spatial dimension is taken out, the spatial dimension is canceled by dividing the ratio of 3D (dimension) and 2D by 2D / 1D in the functional space, and the dimension of the remaining denominator (1 / time) is finally finally. It gives a quantity with a dimension of time as a whole, which is the time constant of gas exchange of the system. Since the scale is (V / A) / (D / L) in this way, as a means to further enhance the functionality of the embodiment of FIG. 6, as a measure against dust, the air flow emitted from the fan / filter unit It has been found that it is effective to make it uniform over the entire ceiling surface (for example, put a fine mesh under the fan filter unit and a "coarse" mesh away from it). However, as an additional gas exchange capability improvement based on the (V / A) / (D / L) ratio, the fan filter unit is installed on the wall facing the wall 9 rather than on the wall 9. It can be seen that it is better to make the above-mentioned "roughness of the eyes" closer to that of the wall 9 and to make it coarser toward the wall 9 and slightly smaller at the side closer to the wall. In this way, in accordance with scaling, a new method that has never existed before is provided for designing a room with high cleanliness and gas exchange capability with extremely clear visibility.
As described above, by using the above formula (15), the area of the gas exchange membrane 26 can be calculated even when the oxygen consumption of the main chamber 20 is different. When gas exchange films having the same membrane microstructure and the same diffusion constant are used, the appropriate area can still be calculated by the mathematical formula (15) even when gas exchange films having different thicknesses are used. In addition, even if the gas exchange membrane has unknown performance such as air permeability, the performance can be grasped and performed internally by performing the experiment described here once after controlling the area and thickness of the gas exchange membrane. The area of the gas exchange membrane can be calculated according to various modes according to the work, and thereafter, the main chamber 20 can be freely designed. Further, the formula (12) is a formula when the rotation of the air flow in the room is good and it is not necessary to consider the space dependence. Therefore, in the case of a room not provided with such a mechanism, or when the mechanism is stopped even if the mechanism is provided, it is necessary to consider the position dependence. However, even in such a case, once the experimental values of the oxygen concentration in the room at the area A and one oxygen consumption rate can be obtained by the experimental measurement, the oxygen consumption situation is different thereafter. However, it is important to be able to obtain the required area A of the gas exchange membrane 26 according to the L dependence, B dependence, and D dependence of the equation (15) shown above. Further, the area A calculated in this way is obtained when the wall 2d in FIG. 6 is infinitely separated from the gas exchange membrane 26, that is, when the cavity width of the double wall 9 is very large, in other words, the gas exchange membrane is substantially. Note that 26 is a value that provides an appropriate oxygen supply capacity to the main room 20 even when it is in direct contact with the outside world (for example, outdoors or corridor space). That is, as a case where the thickness of the double wall 9 is substantially infinite, a case where the gas exchange membrane 26 is present alone at the interface between the main chamber 20 and the outside world is also included in the embodiment of the present invention.
The above D / L value for the gas exchange membrane 26 to be used can be calculated as follows. Therefore, the oxygen permeability was measured by changing the type of the gas exchange membrane 26. For the measurement of this oxygen permeability, the oxygen permeability measuring devices shown in FIGS. 14A and 14B were prepared. As shown in FIGS. 14A and 14B, a rectangular parallelepiped container 101 was prepared using a transparent acrylic plate. The size of the container 101 is about 20 cm in width, about 15 cm in depth, and about 30 cm in height. A rectangular opening 101b is formed in the center of the front wall 101a of the container 101, and a gas exchange membrane 26 for measuring oxygen permeability is attached from the outside so as to cover the opening 101b. Fill with tape or the like so that the outer peripheral portion of the gas exchange membrane 26 and the wall 101a are sealed. A commercially available digital platform scale 102 that can measure in units of 0.1 g was placed on the bottom surface of the container 101, and a plastic basket 103 was placed on it. A candle 104 was erected on the bottom of the basket 103. The candle 104 was ignited and, as a function of time, the oxygen concentration in the container 101 and the burned amount of the candle 104 (meaning the burned weight, corresponding to the oxygen consumption) were measured. As the gas exchange film 26, various shoji papers (Asahipen 5641 (manufactured by Asahipen Corporation), Nao Japanese paper (thick), Nao Japanese paper (hair pattern), Nao Japanese paper (brown), Nao Japanese paper (blue), Naobei (trade name)) and cloth-like Tyvek (registered trademark) manufactured by DuPont Corporation were used. FIG. 15 shows the time change of the oxygen concentration in the container 101, and FIG. 16 shows the time change of the burning amount of the candle 104. With respect to the gas exchange film contained in the portion indicated by {in FIG. 15, the oxygen concentration decreased rapidly, and the candle 104 finally disappeared. That is, the vinyl film (marked with ) used as a reference (which can be regarded as having almost zero gas exchange capacity) was the earliest in less than 3 minutes, the candle 104 disappeared, and the wax-made Nao Washi (blue) (+) (Mark) and Nao Washi (thick) ( mark), the candle 104 disappeared in about three and a half minutes and four and a half minutes, respectively. Gas exchange membrane contained in the part surrounded by the broken line in Fig. 15 (Asahipen 5641; mark, cloth-like Tyvek; * mark, Nao Japanese paper (hair pattern); mark, Nao Washi (brown); × mark, Naobei; mark), although the flame itself became smaller, the candle 104 basically did not go out until the end. In the gas exchange membrane indicated by the broken line arrow in FIG. 16, the oxygen concentration decreases rapidly, the candle 104 finally disappears, and the amount of combustion of the candle 104 is small. On the other hand, the gas exchange film (Asahipen 5641; mark, cloth-like Tyvek; * mark, Nao Japanese paper (hair pattern); mark, Naobei; mark, Nao Japanese paper included in the part surrounded by the broken line in Fig. 16 (Brown); x mark) means that the flame itself became smaller, but the candle 104 did not go out until the end. From FIG. 16, Asahipen 5641 (marked with ) has a high oxygen permeability because the oxygen concentration is relatively high compared to other shoji papers as shown in Fig. 15 despite the large amount of combustion. It turns out to have. Cloth-like Tyvek also has good properties. For paraffin, which is the main component of candles, a chemical reaction formula similar to the chemical reaction formula (1) was established, and the combustion rate B was set from Fig. 15 and V from Fig. 16.<sub>O2</sub>The above D / L can be calculated by calculating / V-η (here, the difference between the oxygen concentration values at two different times). It can be confirmed by this actual measurement that the value is about 0.1 m / min to 5 m / min depending on the material of the gas exchange membrane 26. This result is consistent with the analysis results independent of the above experiment described in connection with the determination of the shoji paper area described above.
In this way, a Japanese-style space with shoji doors and shoji windows is constructed to maintain a room that does not feel uncomfortable with conventional Japanese-style architecture, and even when performing work or activities that involve a large amount of oxygen consumption, the room While maintaining the air environment inside the room suitable for human survival, the air cleanliness in the room is US It is possible to obtain an extremely good clean space that easily exceeds the 209D class 100 and approaches the same class 1. In this way, by using the gas exchange film 26 as an ancient Japanese shoji paper, the neat appearance of the traditional "Shoin-zukuri" can be re-appeared while having modern high-clean environmental characteristics. For example, it is suitable for restaurants and taverns. In addition, it is expected that the harmful effects of second-hand smoke can be reduced in these spaces. By expanding to housing, restaurants, hospitals, and nursing homes around the world, we can expect that it will greatly contribute to the future well-being of humankind on earth.
FIG. 17 shows a photocatalytic filter (photocatalytic deodorizing unit for central air conditioning MKU40: Nippon Tokan) in series with the upstream side of the fan filter unit 21 inside the gas flow path 24 in the highly clean room system 10 of the present embodiment. (Made by Package Co., Ltd.) is placed, and after a certain amount of alcohol is volatilized in the main room 20, the air volume is 11 [m.<sup>3 </sup>/ min.] Is a schematic diagram showing a change in the concentration of alcohol contained in the air in the main chamber 20 when the fan / filter unit 21 is operated. As shown in FIG. 17, 1 minute after the start of operation of the fan / filter unit 21, the offensive odor of alcohol contained in the air in the main room 20 and felt by humans is half that before the start of operation, and 3 minutes later, It becomes almost zero.
FIG. 18 shows the degree of offensive odor of the air freshener contained in the air in the main chamber 20 when the air freshener is volatilized in a certain amount in the main chamber 20 and operated in the same configuration as above. It is a figure. As shown in FIG. 18, one minute after the start of operation of the fan / filter unit 21, the odor felt by humans regarding the air freshener (propylene glycol, etc.) contained in the air in the main chamber 20 is 5 before the start of operation. It becomes one-third, and after two minutes, it becomes almost zero. In this way, the concentration of the substance that causes the odor in the main chamber 20 can be reduced in a considerably short time.
The results shown in FIGS. 17 and 18 show that S σ is the amount of chemical substance generated, n is the chemical substance concentration, and γ is the decomposition of the photocatalyst per filter pass, when there is no air in or out inside and outside the photocatalyst. The above-mentioned formula (3), which was read as efficiency, and the effect of the exponential concentration reduction shown by the solution (see formula (4)), and the other with the outside world through the gas exchange membrane 26. It is a manifestation of the synergistic effect of the effect of trying to reach the equilibrium state of the present invention, which is a proof of the extremely efficient action of the present invention.
As described above, when a 100% circulation feedback system provided with a photocatalytic filter inside is used, it is possible to reduce the concentration of chemical substances generated in this closed space and staying inside extremely quickly. This is due to the synergistic effect of the photocatalyst and the 100% circulating feedback system, in which the chemical substances in this closed space are reduced exponentially by repeatedly contacting the photocatalyst by the 100% circulating feedback system, and the gas. It is derived from the gas exchange function of the exchange membrane 26. That is, even if the photocatalyst is incorporated into a conventional clean unit that does not have a closed circulation feedback system configuration, the photocatalytic effect is small in the open system, but in the highly clean room system 10 of this embodiment, the dust is reduced by the closed circulation. , The function of the photocatalyst can be specialized in the original role of decomposition of chemical substances. As a result, in the highly clean room system 10 of the present embodiment, it is possible to realize both long life and high functionality in both the dust filter and the photocatalyst.
From these facts, for example, by applying this highly clean room system 10 in a closed space such as a nursing home, a nursing home, or a hospital room where an odor is likely to be generated, even if an odor is generated indoors, it can be instantaneously generated. Since it can be disassembled, the living environment can be dramatically improved. In addition, for example, even if a chemical substance invades from the outside or a chemical substance is generated inside, the concentration of the chemical substance inside the closed space can be reduced to several minutes by operating the 100% circulation feedback system after sealing the space. Can be set to almost 0. In particular, in this embodiment, since it is possible to realize an environment free of harmful gas / offensive odor by making the inside of the room 1 and particularly the inside of the main room 20 sterile and dust-free, for example, a small tree in the main room 20 By placing plants that have favorable effects for humans, such as foliage plants and herbs, you can experience the best-in-class "forest bathing" even in the middle of the city, wherever you are. Furthermore, by actively introducing lavender and other aroma scents that meet the needs of each user, we will maximize the quality of the environment, especially the air, which is the greatest luxury of modern people in the future. , Relaxation, etc., can maximize the positive effects on people's bodies. Further, for example, even a patient with multiple chemical sensitivity or asthma who causes allergic symptoms to a specific chemical substance by forming a part of the inner wall of this closed space with a gas exchange membrane 26 or the like. In this space, you can stay for a long time without aggravating asthma and allergic symptoms. In addition, for example, by operating the respiratory organs in a dust-free and sterile environment for about 8 hours a day at bedtime, for example, "no-load operation", short-term fasting to the digestive organs is said to be effective. The same effect can be expected. In addition, for example, by making the living and treatment space a highly clean space of, for example, US 209D class 1 to 10, it is a dust-free and chemical-free environment with "less background noise". It is expected that if the drug is administered via the respiratory tract, especially the lungs, in the environment, the treatment can be performed in a situation where the above-mentioned "S / N ratio" is dramatically improved. In other words, medical processes such as medication can be performed without the influence of more than 1 billion dust in the conventional environment. In Japan, where the aging population is increasing, and in other countries around the world, where the same is expected in the future, the hospital application and home medical application of this highly clean room system 10 has enormous potential.
When a 100% circulation feedback system equipped with a photocatalytic filter in series in the flow direction is connected to a closed closed space and operated with respect to the dust filter provided inside the fan filter unit 21, the inside of this closed space is reached. The decomposition effect of chemical substances is dramatically improved. On the other hand, since the dust filter and the photocatalyst filter are provided in series in the flow direction, the pressure loss with respect to the flow becomes large, and the air volume that can be supplied into the closed space decreases. To deal with this problem, the fan of the fan / filter unit 21 should have a high power with a large maximum static pressure, and the pressure loss of the filter for removing dust should be reduced. The former is a form that should be avoided if possible from the viewpoint of energy saving because the cost increases and the power consumption also increases. Further, in the latter case, since the pressure loss due to the filter is reduced by lowering the dust collection rate of the filter, the dust collection performance of the conventional air cleaning system, which largely depends on the dust collection rate of the filter, is lowered. That is, although this latter cannot be adopted in the conventional clean system, it can be adopted in the highly clean room system 10 according to the mathematical formula (4) shown above, and high performance can be exhibited.
In FIG. 19, in the main room 20, the dust filter provided inside the fan filter unit 21 is operated as a medium-performance filter having a dust collection rate of 0.95 for several minutes, and the number of dusts in the main room 20 is measured. It is a schematic diagram which showed for each particle size. Figure 20 is a schematic diagram showing the total number of dust particles with a particle size of 0.5 [μm] or more per cubic foot among the dust particles in the main chamber 20 measured in this experiment, and is evaluated as it is according to the US 209D standard. Corresponds to the cleanliness of the main room 20 when
As shown in FIG. 19, the number of dust particles in the main chamber 20 4 minutes after the start of operation of the fan / filter unit 21 is less than 1000 dust particles having a particle size of 0.3 [μm]. The number of dust particles with a diameter of 0.5 [μm] is much less than 100, and the number of dust particles with a particle size of 0.5 [μm] or more is 10 or less. Focusing on the total number of dust particles with a particle size of 0.5 [μm] or more per cubic foot, as shown in Fig. 20, dust with a particle size of 0.5 [μm] or more in the main chamber 20 within 10 minutes from the start of operation. The total number of dust per cubic foot began to drop below 100, and 40 minutes after the start of operation, the total number of dust per cubic foot reached around 10, and this value was maintained thereafter in the US 209D class. A space with good cleanliness of 10th grade can be obtained.
Thus, even if the dust collection rate γ is 0.95, the US 209D It is possible to obtain a high-quality clean environment with class 10 cleanliness. For this reason, in this highly clean room system 10, the required level of "should be close to 1" for the dust collection rate of the filter can be significantly lowered, and the margin generated by this can be added value such as a photocatalytic function. It can be used for granting. As a result, clogging of the dust filter is less likely to occur, and the life is dramatically extended. Further, in this case, a plurality of 100% circulating feedback systems may be connected to the main room 20. Of the plurality of 100% circulating feedback systems, for example, one is a 100% circulating feedback system having a fan filter unit 21 having a low dust collection rate but having a photocatalyst and a filter specialized for chemical substance decomposition. The other is a 100% circulating feedback system with a fan filter unit 21 equipped with a filter specialized for collecting dust, so that the advantages of both can be maximized. Here, the main 100% circulation feedback system, as described above, is accompanied by a gas flow path 24 that airtightly communicates the suction port and the gas inlet to the fan filter unit 21 with the outlet 22. If there is a distance from the opening 23, which is the suction port provided at the bottom of the partition wall, so that the air in the room can be moved throughout without "short circuit". The "subordinate" circulation feedback system that accompanies this "main" 100% circulation feedback system does not necessarily require a strict gas flow path like the main loop, even though it is a 100% circulation feedback system, but simply. It is also recommended to place an air purifier with the same injection amount and suction amount in a part of the room where the wind moves by the main circulation system, for example, when the device is operated in a semi-open space. High cleanliness that cannot be achieved at all is achieved.
FIG. 21 shows, in this embodiment, an air purifier (KPD1000 manufactured by Fuji Film Co., Ltd.) using a commercially available photocatalyst or metal radical for the fan / filter unit 21 constituting the 100% circulation feedback system provided in the main chamber 20. It is a schematic diagram showing the number of dusts in the main chamber 20 for each particle size after operating for several tens of minutes. FIG. 22 is a schematic diagram showing the total number of dusts having a particle size of 0.5 [μm] or more per cubic foot among the dusts in the main chamber 20 measured in this experiment. KPD1000 has an air volume of 0.55 [m<sup>3 </sup>/ min.] Was driven.
As shown in FIG. 21, the reduction rate of the number of particles depends on γ shown in the equation (1). This is also clear from equation (4). In the figure, the number of particles decreases rapidly for a large particle size of 10 [μm], whereas γ ~ 1 is a good approximation. However, it can be seen that the reduction rate of the number of particles decreases as the particle size decreases toward 5 [μm], 1 [μm], 0.7 [μm], 0.5 [μm], and 0.5 [μm]. That is, it can be seen that the collection rate γ of this KPD1000 differs depending on the particle size. By comparing the reduction rate of the number of particles obtained from the data shown in Fig. 22 with the coefficient over time t of the exponential function part of equation (4), V and F are known, so γ is calculated. Can be calculated. According to this calculation, for example, for a particle size of 5 [μm], γ = 0.75, and for a particle size of 1 [μm] and a particle size of 0.7 [μm], γ = 0.37, a particle size of 0.5 [μm]. For γ = 0.33, for particle size 0.3 [μm], γ = 0. It is calculated as 29. As described above, it can be seen that the γ for particles having a particle size smaller than 1 [μm] is about a fraction of the γ for particles having a particle size of 10 [μm]. The KPD1000 is equipped with an ostrich egg filter and focuses on virus removal and odor removal. The collection efficiency γ is considerably lower than 1 especially for smaller particle sizes, but it has only this level of γ. It shows that even the absence of a filter can achieve the relatively good cleanliness of the US 209D Class 200. By incorporating the low-priced but reasonably low-performance filter and photocatalyst system of this example into the 100% circulation feedback system, the unique feature of being able to produce performance comparable to that of a high-performance filter is unfortunately demonstrated. ing. In addition, by using the 100% circulating feedback system, which is a component of the present invention, as shown in FIGS. 23 to 25, Nao Washi (hair pattern), Imari Washi, and cloth-like Tyvek (registered trademark) can be used. When used as a filter for a fan / filter unit, it is possible to obtain collection efficiency for each particle size. This is of great help in controlling the microbial environment and can provide a new medical, medical and nursing environment.
In addition, the γ calculation method described here can also be applied to the shoji paper in which the required area is ordered estimated in the above-mentioned determination of the shoji paper area. That is, how the number of particles of each particle size changes by folding the shoji paper used there to make a filter and operating the fan filter unit incorporating this in 100% circulation feedback operation in a closed space of a certain volume. It was found that even when the shoji paper filter was used, the performance was almost the same as that shown in FIG. 21. For example, when the shoji paper "Naobei" of Dainao Co., Ltd. is used as a shoji paper filter, the particle size is 0.3 [μm], 0.5 [μm], 0.7 [μm], 1.0 [μm], 5.0 [ For μm] and 10 [μm], γ was 0.12, 0.14, 0.18, 0.28, 0.56 and ~ 1, respectively. In addition, when the shoji paper "plain No.5641" of Asahipen Co., Ltd. is used as the shoji paper filter, the particle size is 0.3 [μm], 0.5 [μm], 0.7 [μm], 1.0 [μm], 5. For 0 [μm] and 10, γ was 0.18, 0.21, 0.24, 0.42, 0.71 and ~ 1, respectively. In this way, in the past, with low to intermediate filters, it was not possible to see the dust collection efficiency to the point where the number of particles decayed, and only the gravimetric method and the colorimetric method were used (hence, good accuracy). (Measurement was not possible), but this method, which measures by combining with a 100% circulation feedback system, provides a new method as a measurement method because it has the advantage of being able to measure at once while discriminating the particle size. It can be said that there is. On the other hand, scaling the room by (V / A) / (D / L) described above is another aspect, which is a new method discovered by the present inventors and is an excellent feature. Considering that these two features will be combined to bring about a synergistic effect in the future, it can be said that the system shown in this example plays an extremely important role in the technological development and analysis of a clean environment.
It can be said that the cleanliness of the above US 209D class 200 class is astonishing as a value obtained by using a filter in which the collection efficiency γ of 0.5 μm particles is far below 1. For example, even if this air purifier (KPD1000: manufactured by Fuji Film Co., Ltd.) is used in normal clean room usage, the amount of dust is the atmospheric dust number density N.<sub>0 </sub>However, as is clear from the graph shown in FIG. 22, when used in the system configuration of the above-described embodiment, N is used, while it falls to only about half (hundreds of thousands / cubic feet).<sub>0 </sub>It can be reduced to a value about 3 orders of magnitude smaller. It can be said that this is the direct result of the formula (5) shown above. In addition, as shown in Fig. 21, acetic acid and NH are measured at the same time.<sub>3 </sub>The concentration of both will be 1ppm or less 10 minutes after the start of operation. In this way, by operating the air purifier and the 100% circulation feedback system at the same time, the performance of the air purifier can be dramatically improved.
As described above, in the highly clean room system 10 which is an air purification system of a closed circulation system, the dust collection efficiency does not greatly depend on the dust collection rate of the filter. Therefore, even if the dust collection rate of the filter is lowered, the dust collection efficiency is not significantly reduced as in the case of the open air purification system. In the highly clean room system 10, the margin created by the fact that the dust collection rate does not have to be close to 1 can be diverted to bactericidal and sterilizing properties. In addition, it is highly clean even if a fan / filter unit, for example, a commercially available air purifier, etc., in which the air outlet and the intake port are integrated in the device is installed in a closed space to which a 100% circulation feedback system is connected. The environment can be obtained, and the life of the filter installed in this fan filter unit can be extended. It is also extremely effective to independently install a commercially available photocatalyst such as KPD1000 or an air purifier using metal radicals inside the main chamber 20 equipped with a 100% circulation feedback system. By installing such an air purifier that specializes in virus suppression and odor removal rather than dust suppression in a low dust environment, performance deterioration due to filter clogging due to dust can be suppressed to almost zero, and the original virus does not occur. It can specialize in roles such as activation and deodorization. Further, since the filter is hardly clogged, long-term reliability can be obtained. As described above, in addition to the system of the present embodiment provided with the 100% circulation feedback system, the system using a commercially available purifier or an air conditioner can enhance the cleaning ability by a product rather than a sum, and the combined use. The performance of the new system can be maintained semi-permanently.
Next, the fan filter unit 44 (pure space 1, discharge air volume = [1 m) installed in the front chamber 40<sup>3 </sup>/ min]: The air cleanliness in the anterior chamber 40 when operating alone (manufactured by AS ONE Corporation) will be explained.
FIG. 26 is a schematic diagram showing a change in the number of dust particles in a short time when the fan filter unit 44 constituting the 100% circulation feedback system connected in the anterior chamber 40 is operated. As shown in FIG. 26, after operating the fan filter unit 44, the total number of dust particles having a particle size of 0.5 [μm] or more in the anterior chamber 40 per cubic foot is several hundred thousand before the start of operation. What was there will decrease to about 40,000 per cubic foot, which is one-third in about 5 minutes from the start of operation, and to about 1000 per cubic foot after 10 minutes. After that, this cleanliness is maintained for a long time. In this way, the anterior chamber 40 can effectively reduce the amount of dust inside the anterior chamber 40 in about 5 minutes from the start of operation of the fan filter unit 44.
In Fig. 27, the fan filter unit 44 provided in the front chamber 40 is replaced with a large-capacity fan filter unit, Pure Space 10 manufactured by AS ONE Corporation (maximum discharge flow rate = 11 [1 m).<sup>3 </sup>Change to / min]) and discharge air volume = 11 [m]<sup>3 </sup>It is a schematic diagram showing the results obtained by operating as / min]. As shown in FIG. 27, among the number of dust particles in the anterior chamber 40, the total number of dust particles having a particle size of 0.5 [μm] or more was about 1 million per cubic foot before the start of operation. Things are almost zero in two and a half minutes from the start of operation of Pure Space 10. In addition, the total number of dust particles with a particle size of 0.3 [μm] or more was about 10 million per cubic foot before the start of operation, but 10 in about 2 minutes from the start of operation of Pure Space 10. It becomes as follows. In this way, by appropriately setting the fan / filter unit 44 to be used according to the volume of the anterior chamber 40, it is possible to create an ultra-highly clean environment in the anterior chamber 40 in an extremely short time. From the above, it was demonstrated that the anterior chamber 40 of the highly clean room system 10 of this embodiment can be obtained with extremely high performance as an anterior chamber. For example, this is a space for taking off shoes in a very short time (for about 1 to 2 minutes) while sitting on the "stepping" (space for taking off shoes) of a Japanese-style inn and slowly unlacing the leather shoes. It is shown that the cleanliness of the (anterior chamber) can be improved to about US 209D class 0.1.
Next, a case where a person enters the main room 20 of the high-clean room system 10 via the front room 40 will be described. Before humans enter the main room 20, the doorway 8 and the sliding door 47 are completely closed, and the outside, the front room 40, and the main room 20 are completely separated from each other. In addition, the inside of the main room 20 is kept clean in advance by a 100% circulation feedback system.
Here, when a human enters the anterior chamber 40 from the doorway 8, closes the doorway 8 and starts the 100% circulation feedback system of the anterior chamber 40, the dust of the anterior chamber 40 is quickly collected by the filter as described above, and the front chamber 40 is collected. The cleanliness of room 40 improves rapidly. At this time, oxygen in the anterior chamber 40 is consumed by human breathing, but since the sliding door 47 is covered with shoji paper as a gas exchange membrane 26, oxygen is supplied by the gas exchange function described above. There is no problem with staying in the front room 40.
In this way, with the doorway 8 and sliding door 47 closed, wait for about 2 minutes in the front room 40, then open the sliding door 47 and enter the main room 20 to improve the cleanliness of the main room 20. People can enter and leave the main room 20 from the outside without lowering it.
FIG. 28 is a schematic diagram showing a change in the relative cleanliness of the main room 20 when a person enters from the front room 40 to the main room 20 via the sliding door 47. As shown in FIG. 28, it was demonstrated that there was no change in the cleanliness of the main room 20 before and after entering the main room 20 from the external space through the entrance 8, the front room 40, and the sliding door 47. This is because the doorway provided between the front chamber 40 and the main chamber 20 is composed of a sliding door 47, so there is no volume change when opening and closing, and therefore pressure change and air feeding effect (piston effect). There is no air flow in and out of the main room 20 when humans enter and exit. Therefore, since there is no inflow of dusty outside air, it is shown that the cleanliness of the main room 20 is always kept good. In this way, the high-clean room system 10 is composed of the front room 40 and the main room 20, and the doorway separating the front room 40 and the main room 20 is a sliding door 47, so that the cleanliness inside the main room 20 is maintained. You can go back and forth between the main room 20 and the outside as it is. In addition, the doorway 8 can also be maintained as a door to keep the renovation to a minimum, but the meaning of avoiding the above pressure generation and air feeding effect (piston effect), and in hospitals and special nursing homes, corridors It is more preferable that the doorway 8 is also a sliding door in order to avoid a collision with a passing person or a wheelchair, or when making a new construction. Others are the same as in any of the first and second embodiments.

Then, by entering the main room 20, it is possible to reach the main room 20 from the external space without deteriorating the cleanliness inside the main room 20 at all. Further, by attaching a gas exchange film 26 such as shoji paper to the sliding door 47, it is possible to impart gas exchange ability while bringing out the taste of traditional Japanese shoji. In this way, the gas exchange membrane 26 that forms part of the wall 9 that constitutes room 1 is made of shoji-like filter cloth or shoji paper, and the doorway and the partition between the main room and the front room (stepping) are used as sliding doors. By doing so, it becomes possible to construct the living space 6 in a Japanese style, and the style cultivated in the history of Japan for more than a thousand years is expressed through modern technology and mathematical formulas (1) to (17), which are theoretical analysis formulas. To be sophisticated, not just the concept of long-term excellent housing and energy management, but also a clean air environment, where you can enjoy the best air environment that was common in ancient Japan on a daily basis. It can be revived in the present age. In addition, traditional Japanese lifestyles such as shoji screens, sliding doors, and sliding doors are re-recognized through the present invention as natural and inevitable preparations and procedures for realizing a permanent clean space, not as a shackle. A sliding door style Japanese-style room with a wall that also has a shoji paper gas exchange membrane and an internal space and a 100% circulation feedback system can be transmitted to the world as a state-of-the-art 21st century type excellent living space. Furthermore, since dust that is inevitably generated in a general living space can be actively removed by a dust filter or the like, the inside of the room is dramatically improved compared to a conventional clean room or the like that simply pushes out dust generated in the room to the outside. It can be highly clean and can maintain high cleanliness even if dust is generated inside.

The air inside the chamber 1 is returned to a value extremely close to the same concentration as the outside air by gas exchange with the outside air and mutual concentration diffusion of molecules, and is returned to the inside of the chamber 1. At this time, since there is no exchange of the net air flow, no dust is mixed in from the outside air, and the air is purified only in terms of molecular components. That is, the gas inside the room 1 is exchanged between the outside air introduced from the introduction port 71 and the gas inside the room 1 introduced from the inside air recovery port 72 through the gas exchange membranes 26 arranged in multiple layers. The components are almost equal to those of the outside air and return to the room again.
The gas exchange device 80 will be described individually. As shown in FIG. 35, the gas exchange device 80A is a type that facilitates handling of the air flow by introducing and sending out the outside air and the inside air in parallel, and the gas exchange membrane 26 is formed in a zigzag shape in a single stroke. Since the gas exchange membrane 26 is arranged in the box, there is an advantage that the gas exchange membrane 26 can be composed of a single membrane. Further, as shown in FIG. 36, the gas exchange device 80B has a structure for introducing and sending out outside air and inside air in parallel like the gas exchange device 80A, and further, a type in which a large number of gas exchange films 26 are arranged in parallel. Then, the outside air and the inside air are introduced separately for each slot. With this configuration, there is an advantage that the surface spacing of the gas exchange membrane 26 is constant and the stagnation layer can be reduced in the air flow. Further, as shown in FIG. 37, the gas exchange device 80C is also a type in which a large number of gas exchange membranes 26 are arranged in parallel, but by making the outside air introduction and the inside air introduction directions orthogonal to each other, the introduction port 71 can be put together. The structure can be simplified. Further, as shown in FIG. 38, the gas exchange device 80D combines the advantages of the structures of the gas exchange devices 80B and 80C, and introduces and sends out the outside air and the inside air in parallel, and the outside air and the room 1 Regarding the air inside, there is a merit that the introduction ports can be grouped together. Specifically, the dimensions of the gas exchange section 70 of the gas exchange device 80D are, for example, a height of 45 cm], a width of 90 [cm] and a length of about 180 [cm], and the gas exchange film 26 is, for example. , 3 [mm] or more and 60 [mm] or less at intervals d. This results in 12 [m<sup>2 </sup>] More than 240 [m<sup>2 </sup>] Gas exchange is possible in the following extremely wide effective area. However, d is not limited to the above, and 1 to 2 [mm] is also very effective in shortening the gas exchange time. Therefore, the gas exchange device 80D has tens to hundreds of times the performance of the gas exchange capacity of the gas exchange membrane 26 shown in FIG. 11 described above. As mentioned above, the gas exchange device 80D is equipped with two blower fans, one for the outside air and the other for the room return air (inside air), and since these actively send out the air, two airflows across the gas exchange surface. Taking into account the speed of, it is possible to further improve the gas exchange capacity by about 10 times.
The total area of the gas exchange membrane 26 in the gas exchange device 80 described above is guaranteed to have a sufficient oxygen concentration for a person to act internally if the equation (15) is satisfied at a minimum, and the larger this area is, the larger the area is. In addition to this, the deodorizing and harmful gas discharge functions will also increase. That is, scaling by (V / A) / (D / L)} is also a unit of the repeating structure of gas exchange membrane / inside air / gas exchange membrane / outside air possessed by the gas exchange unit 70 of the gas exchange device 80. The same can be said for "vesicles". For example, in the case of the highly clean room system 10 shown in FIG. 9 or 12, V (~ 24 [m]<sup>3 </sup>]) / A (~ 1.8 [m]<sup>2 </sup>]) ~ 13 [m], whereas in the gas exchange device 80 shown in FIGS. 35 to 38, the surface spacing d of the gas exchange membrane 26 is typically on the order of several [mm], so V (= A × d) / A = d ~ 3 [mm]. From the ratio of the two, 13 [m] / 3 [mm] to 4000 [mm], the time constant of gas exchange of the gas exchange device 80 is 4000, for example, from the quantity on the order of "40 minutes" observed in Fig. 13B. It turns out that it is one-third as short, that is, the time is on the order of less than one second. For example, volume 30 [m<sup>3 </sup>], The air volume of the outside air and inside air flowing into the gas exchange device 80 is 0.25 [m] depending on whether it is steady or emergency.<sup>3 </sup>/ min] ~ Dozens [m]<sup>3 </sup>It takes a value of about / min] (this value scales with respect to the volume of the room), so it is a typical size of the above gas exchange device 80 (0.45 x 0.9 x 1.8 [m].<sup>3 </sup>] ~ 0.8 [m<sup>3 </sup>]), The time it takes for the airflow to pass through the device is from a few seconds to about 1 minute. Since this is several times or more the gas exchange time constant of the gas exchange device 80 described above, the outside air and the inside air sufficiently exchange gas while flowing inside the gas exchange device 80, and at the outlet portion, the gas exchange is sufficiently performed. It can be seen that both can reach a near equilibrium state. In this way, the gas exchange between the outside air and the air in the room 1 is to efficiently diffuse the mutual concentration of molecules between the two airflows that flow across the surface at the center of each gas exchange surface. Can be done. It is desirable that the air volume of the outside air flowing into the gas exchange device 80 is equal to or greater than the air volume of the inside air flowing into the gas exchange device 80. Preferably, the air volume of the inside air flowing in the gas exchange device 80 is several to 10 times or more, but at the same time, two airflows of the inside air and the outside air flowing across the gas exchange film are used. It is desirable to make the pressure difference through the gas exchange membrane almost zero according to Bernoulli's theorem by arranging a large parallel component in the velocity vector. It is best that the velocity vectors of these two airflows are perfectly parallel, but it is also very effective to cross the two gas exchange surfaces diagonally with the surface in the center. Therefore, it is important to make the cross-sectional area of the portion through which the outside air flows larger than that of the inside air so as to offset the above-mentioned air volume ratio. That is, it is preferable that the ratio of the outside air flow rate / the inside air flow rate in the gas exchange device 80 matches the ratio of the gas exchange membrane interval in the outside air flow path / the gas exchange membrane interval in the inside air flow path. When the air flows on both sides of the gas exchange film 26 are parallel or quasi-parallel, the cross section of the gas exchange film 26 cut at a plane orthogonal to the direction of this flow is zigzag (mountain fold valley fold). It is also effective to increase the effective area as a shape and enhance the gas exchange capacity.
FIG. 39A shows an actual machine (prototype) of the gas exchange device 80C shown in FIG. 37, and FIG. 39B is a top view of the gas exchange device shown in FIG. 39A. Figure 39A shows the airflow arrangement of the gas exchange device. The length of the gas exchange device is about 90 cm, the width is about 60 cm, and the total thickness of the multilayer structure is about 20 cm. FIG. 40 shows an example in which the gas exchange device shown in FIG. 39A is incorporated in the room of the highly clean room system 10. In the rectangular parallelepiped room on the left side of Fig. 40, 5 of the 6 sides are vinyl and the remaining 1 is Tyvek, and after completely sealing this space, oxygen is consumed by cooking a gas stove inside. In this situation, FIG. 41 shows the results of measuring the oxygen concentration in the closed space with and without the operation of the gas exchange device. When the gas exchange device is not operated, the oxygen concentration continues to decrease below 19%, as shown in FIG. However, when the gas exchange device is operated, the decrease in the internal oxygen concentration stops decreasing and becomes constant at a little less than 20%. It proves that the gas exchange device has excellent gas exchange ability. The target oxygen concentration can be realized by setting the size and total number of gas exchange membranes and the flow rate according to the formulation and formula 17 described above based on the D / L obtained by the method described in detail. .. As can be seen from the above analysis, this gas exchange device can be considered as the limit when the V / A of the room in the present invention is small, and therefore, it can be regarded as the limit type of the hollow wall provided with the gas exchange film of the present invention. Therefore, the gas exchange device can be used to replace the hollow wall provided with the gas exchange film of the present invention, depending on the application.
Further, for example, if the gas exchange device 80 provided in the high-clean room system 10 shown in this embodiment is a gas exchange device 80D, a gas exchange film provided inside the gas exchange unit 70 of the gas exchange device 80D. 26 will be lined up perpendicular to the ceiling wall 2a. That is, the normal vector of the surface of the gas exchange membrane 26 is orthogonal to the direction of gravity. Therefore, various dusts contained in the outside air do not fall on the surface of the gas exchange membrane 26, but only stay on the wall surface constituting the gas exchange unit 70, for example, on the surface in front of FIG. 38. Therefore, the gas exchange capacity of the gas exchange membrane 26 of the gas exchange device 80D is remarkably released from the problem of clogging.
By configuring the high-clean room system 10 as described above, it is possible to realize the high-clean room system 10 provided with a local exhaust system. For example, by using this highly clean room system 10 when local exhaust is desirable, such as when changing diapers in a nursing home, it is possible to deal with the generation of local offensive odors without sacrificing internal cleanliness. Become. In addition, this highly clean room system 10 can safely perform a painting process using a solvent or the like while maintaining a clean environment. Other than that, it is the same as the highly clean room system 10 of the embodiment of any of the second to eighteenth embodiments.
According to the eighth embodiment, it is possible to realize a highly clean room system 10 having the same advantages as those of the first to seventh embodiments and having a local exhaust system. For example, by using this highly clean room system 10 when local exhaust is desirable, such as when changing diapers in a nursing home, it is possible to deal with the generation of local offensive odors without sacrificing internal cleanliness. Become. In addition, this highly clean room system 10 can safely perform a painting process using a solvent or the like while maintaining a clean environment.

The outside air introduction port 11e and the inside air discharge port 11f are provided, and the top surface of the wall 9 is provided so as to be flush with the ceiling wall 2a. As for the configuration of the anterior chamber 40, the configuration of the anterior chamber 40 shown in the third embodiment can be appropriately selected. Of the internal configuration of room 1, the part other than the front room 40 constitutes the main room 20, so by providing the front room 40 in room 1, the cleanliness of the main room 20 is not compromised. You can go back and forth between the room and the outside. For example, a photocatalyst 61 may be further provided inside the gas flow path 24 of the main chamber 20. Whether or not the photocatalyst 61 is installed can be appropriately selected according to the use of the main chamber 20. Specifically, the configuration of the main room 20 side of the room 1 is such that a fan filter unit 21 is provided in the ceiling 5 above the main room 20 so that air can be blown to the main room 20. A part of the wall 9a that separates the 20 and the internal space 7 is composed of a gas exchange film 26, and the air in the internal space 7 and the air in the main room 20 can exchange with each other.
An outside air introduction duct 83a and an exhaust duct 83b are provided on the ceiling wall 2a on the ceiling 5 side in the main room 20. The outside air introduction duct 83a is provided so as to cross four consecutive rooms 1, and the outside air intake port 85, which is one end of the outside air introduction duct 83a, has a ventilation mechanism 82 such as a sirocco fan.

The outside air introduction duct 83a is provided so as to connect the outside air introduction ports 11e of each room 1 in order with airtightness, and introduces the outside air into the internal space 7 to the outside air introduction ports 11e of each room 1. Tube 83c is connected. Further, the exhaust duct 83d is provided so as to connect the inside air discharge port 11f of each room 1 in order with airtightness, and the gas is discharged from the inside space 7 to the inside air discharge port 11f of each room 1. The pipe 83d is connected. With this configuration, the outside air sucked from the outside air intake port 85 is sequentially introduced into the internal space 7 of the wall 9 of each room 1 through the outside air introduction duct 83a and the outside air introduction port 11e, and each room. The inside air discharged from the internal space 7 of the wall 9 of 1 through the inside air discharge port 11f is sequentially discharged, and is discharged from the exhaust port 86 through the exhaust duct 83b.

To. This configuration increases the air circulation efficiency when the air introduced from the outside air intake port 85 is warm, for example, in summer, but is not limited to this, and for example, the lengths of the pipes 83c and 83d are reversed. By doing so, it is possible to form a structure in which the air circulation efficiency is enhanced when the air introduced from the outside air intake port 85 such as winter is cold. In particular, the latter has a large parallel component in the velocity vectors of the two airflows sandwiching the gas exchange membrane 26. This is also the recommended layout. At least a part of the outside air introduction part and the discharge part in the internal space 7 is selected from the region in the internal space 7 in which the gas flow path 24 is not formed.
Two fan filter units 78 are mounted at two corners on the inner wall 9a side in the main room 20. The fan filter unit 78 is basically limited as long as the air volume is at least a fraction of the air volume of the fan filter unit 21, preferably one digit or more smaller, and has dust removal ability and ventilation ability. No, but for example, if the volume of the main room 20 is V, then V / 2h [m<sup>3 </sup>It is preferably more than / h], and the air supply amount is 15 [m].<sup>3 </sup>/ h] or more 66 [m<sup>3 </sup>A small flow rate fan / filter unit of [/ h] or less is preferable. As the small flow rate fan / filter unit, for example, Blue Air Mini (trade name) manufactured by Blue Air Co., Ltd. is suitable. FIG. 43 is a perspective view showing an overview of the small flow rate fan / filter unit. This small flow rate fan / filter unit is configured by combining the filter unit 78b with the main body 78a so that the air sucked from the back surface of the filter unit 78b is blown out from the front surface of the main body 78a. A ventilation mechanism is provided inside the portion 78a.

In addition, two fan filter units 78 are installed at the boundary between the internal space 7 and the main room 20, and the other fan filter unit 78 is inside air so that one fan filter unit 78 introduces outside air. It can also be used as a ventilation mechanism between the main room and the outside by installing it so as to exhaust the air. In this case, one of the two fan filter units 78 takes in the outside air and the other exhausts the inside air. Therefore, even in this case, the life and efficiency of the fan filter unit 78 for exhausting the inside air can be extended by an open system. It is maintained that it can be increased several hundred times or more compared to the case of using it. Further, these two fan / filter units 78 may be installed between the main room 20 and a corridor, an outdoor area, or the like. This allows, for example, "rotary replacement" of replacement of these small flow rate fan filter units over time. That is, it is recommended to replace the aging blower mechanism 82 on the outside air intake port 85 side with the fan filter unit 78 that has been used for the inside air exhaust, and to install a new fan filter unit 78 for the inside air exhaust. Others are the same as in any of the first to eighth embodiments.

The subject went to bed. This corresponds to the case where the area A takes the maximum value structurally permitted in the tent-like structure alone in the equation (16). In addition to this, in order to provide equivalent gas exchange capacity, the gas exchange device shown in FIGS. 35 to 38 is closed in the tent (as shown in FIG. 34 as an example of connection with a closed space and a room). It may be used by placing it outside the space. In this case, the tent itself does not have to have the gas exchange capacity, so for example, when making a tent-like structure using a vinyl material (which is highly waterproof but not breathable) and going to bed in it. It is suitable for. The area A of the gas exchange membrane 26 is a value that satisfies the above-mentioned required area condition and provides an appropriate oxygen supply capacity inside the tent. A fan filter unit (FFU) and a dust counter (particle number measuring instrument) were installed on the floor inside the tent.

It is shown that. Figures 48A and 48B are measurement data from May 31 to June 1, 2013, and Figures 49A and 49B are measurement data from June 1 to June 2, 2013, Figure 50A. And Fig. 50B is the measurement data from June 2 to June 3, 2013, Fig. 51A and Fig. 51B are the measurement data from June 3 to June 4, 2013, Fig. 52A and Fig. 52B shows the measurement data from June 4th to June 5th, 2013, and Fig. 53A and Fig. 53B show the measurement data from June 5th to June 6th, 2013. In addition, Fig. 54A and Fig. 54B show the measurement data from April 29 to April 30, 2014, and Fig. 55A and Fig. 55B show the new filter from April 30 to May 1, 2014. The data measured using the FFU replaced with is shown. For about 11 months from the data of FIGS. 53A to 53C to the acquisition of the data of FIGS. 54A to 54C, the subject (the first inventor of the present invention) was on a business trip while operating the system. I went to bed almost every day except when I was absent. Comparing Figure 48B, Figure 49B, Figure 50B, Figure 51B, Figure 52B and Figure 53B with Figure 54B, the resting cleanliness baseline is US 209D. It maintains class 100 and shows that the cleanliness does not deteriorate at all even after long-term operation. This is because the FFU used is very different from the FFU usage in a conventional clean room, and because it operates in isolation from the outside world, it is free from the originally unnecessary "clogging due to the intake of outside air". according to. In fact, even when compared with Fig. 55B (sleeping cleanliness ~ 700) experimented with a new D filter, Fig. 54B shows rather good cleanliness ~ 400 (sleeping resting). ing. 48C, 49C, 50C, 51C, 52C, 53C, 54C and 55C are the data of FIGS. 48A, 49A, 50A, 51A, 52A, 53A, 54A and 55A, respectively. More autocorrelation function<maths num="18"><img id="000029" he="16" wi="159" file="JP5877459B2_D0001.tif" img-format="tif" img-content="drawing" /></maths>The amount of correlation (value of autocorrelation function) calculated using is shown. Here, the lower limit of the integration is the measurement start time (sleeping start time, t = 0), and the upper limit is the measurement end time (or the latest measurement time up to that point, if monitoring is performed at any time).<sub>end </sub>As t<sub>end </sub>Set to / 2. These n (t) and F (τ) are called t-Hypnokinetogram and τ-Hypnokinetogram, respectively, in the sense that they represent unconscious body movement information during sleep. It is expected that this waveform and graphic data accumulation (big data conversion) and its analysis will enable new findings and diagnoses, as well as judgment of the need for medical measures, as in the case of electrocardiogram and electrosurgical analysis. .. Since there is no need to attach a probe or the like to the body, it is considered to be highly valuable because it is information that truly reproduces a normal life and sleep state.
From FIGS. 48A to 55C, there is a clear tendency that the density of dust particles and the amount of correlation during sleep are considered to reflect the sleeping state. Specifically, the density of dust particles is high immediately after the start of sleep, but the density of dust particles decreases sharply, and then about US 209D. Although the cleanliness of class 1000 or higher is maintained, it can be seen that the dust fine particle density rises sharply in a peak shape approximately every 90 minutes. This time of about 90 minutes corresponds to one cycle of the pattern of "non-REM sleep REM sleep". This tendency is clearly shown in FIGS. 48C, 49C, 50C, 51C, 52C, 53C, 54C and 55C showing the time course of the correlation amount. From this, it can be seen that the dust fine particle density n (t) reflects the sleep state, and the correlation amount reflects the sleep state. Specifically, for example, FIGS. 48A to 48C show the data of the evening when a relatively deep sleep was obtained, but a long-period structure can be seen. On the other hand, FIGS. 51A to 51C show data of the evening when the sleep was relatively light, but a short-period structure can be seen. If you look carefully, you can see that the short-period structure in Fig. 51C is superimposed on the long-period structure in Fig. 48C. That is, the spectrum envelope (envelope) of FIG. 52C is substantially equal to that of FIG. 49C at τ to 90 minutes and τ to 180 minutes. This suggests sharing some identical process. However, the high frequency component in FIG. 52C and the presence of the peak around τ ~ 110 minutes indicate that there is some difference between the two at the same time. By accumulating data and correlating it with the complaint situation on the day, it is expected that it will be possible to analyze the health condition and divide the cases in detail in the non-illness state. For the first time, non-invasive and non-contact measurements revealed that higher-order structures appeared while maintaining one cycle of the "non-REM sleep-> REM sleep" pattern for a time of about 90 minutes.
Thus, Fig. 48C, Fig. 49C, Fig. 50C, Fig. 51C, Fig. 52C, Fig. 53C, Fig. 54C and Fig. 55C each show a characteristic spectrum, and sleep information and higher-order (health) information derived from it are shown. Can now be measured when the subject is unconscious by a non-contact, non-invasive method. It can be seen that the dust fine particle density rapidly increases in a peak shape from the end of REM sleep in the latter half of one cycle to the onset of non-REM sleep in the next cycle. In addition, as can be seen from the figures of FIGS. 48B, 49B, 50B, 51B, 52B, 53B, 54B and 55B, the baseline at rest is the tent-type high cleanliness shown in FIGS. 46A and 46B. US 209D depending on the condition of the gap between the system and the bedding as well as the floor The value is between 100 and 1000 in the class, but the tent type high cleaning system has a tent type high cleaning system that improves the adhesion with the floor surface (when using a futon) from the outside with a weight such as a towelette. It has also been confirmed that increasing the airtightness of the interior space leads to a high degree of cleanliness of the US 209D class 10 to 1 level, which is comparable to that of Fig. 10 and Fig. 11.
[Example 3 of sleeping situation detection system] 56A, 56B, 56C and 56D are a perspective view, a front view, a side view and a top view showing a highly clean cot system in which a highly clean space is formed on the cot. As shown in FIGS. 56A, 56B, 56C and 56D, in this highly clean cot system, a cot with the bed 302 mounted on a supporting frame 301 is installed on the floor 303 of the room. There is. One end of the bed 302 is in contact with or in close proximity to the side wall 304 of the room. On the other end side of the bed 302, the fan filter unit 306 is installed on the gantry 305 installed on the floor 303. The fan filter unit 306 is installed on the longitudinal centerline of the bed 302. The fan filter unit 306 is adapted to suck in air from the air suction port at the lower part thereof and discharge clean air upward from the air discharge port at the upper part. A blower guide plate 307 is mounted on the gantry 305. The blower guide plate 307 extends vertically to a position slightly higher than the height of the fan filter unit 306, but the upper part thereof is curved toward the bed 302 side. The air discharged from the upper part of the fan filter unit 306 to the upper side hits the curved portion of the upper part of the blower guide plate 307 and flows on the upper side of the bed 302 in the direction parallel to the bed 302. The entire frame 305, fan filter unit 306, and blower guide plate 307 are covered by the enclosure 308 except for the air exhaust part. The enclosure 308 is made of an airtight material. Above the cot, a curtain rail 311 is installed parallel to the bed 302 while being supported by a hanging bar 310 fixed to the ceiling 309. The curtain rail 311 has a U-shaped planar shape that is slightly smaller than the bed 302. Both ends of the curtain rail 311 are fixed to the side wall 304. Curtain rail 311 The inner gas exchange membrane 312 is suspended. The inner gas exchange membrane 312 has a size capable of covering the entire cot. The hem of the inner gas exchange membrane 312 is located at a height of, for example, about 10 cm above the floor 303. The inner gas exchange membrane 312 can be moved along the curtain rail 311, and the space surrounded by the inner gas exchange membrane 312 can be opened. One end of the inner gas exchange membrane 312 in the longitudinal direction is fixed to the side wall 304 with a seal, and the other end can be detachably fixed to the side wall 304 with Velcro (registered trademark) or the like. An outer gas exchange membrane 313 is attached to the side surface of the curtain rail 311. The outer gas exchange film 313 is provided so as to overlap with the inner gas exchange film 312 within a certain height range, for example, about 30 cm below the curtain rail 311. By overlapping the inner gas exchange membrane 312 and the outer gas exchange membrane 313 in this way, a gap is not formed between the inner gas exchange membrane 312 and the outer gas exchange membrane 313, so that dust particles from the outside are removed from the inner gas. It is possible to prevent the invasion of the space surrounded by the exchange membrane 312. Further, the inner gas exchange membrane 312 and the surrounding body 308 are similarly overlapped with each other by having a constant length in the height direction, for example, a length of about 20 cm, so that the inner gas exchange membrane 312 and the surrounding body 308 are similarly overlapped. No gaps are formed between them, so that it is possible to prevent dust particles from the outside from entering the space surrounded by the inner gas exchange film 312. It can be detachably fixed to 4. An outer gas exchange membrane 313 is attached to the side surface of the curtain rail 311. The outer gas exchange film 313 is provided so as to overlap with the inner gas exchange film 312 within a certain height range, for example, about 30 cm below the curtain rail 311. By overlapping the inner gas exchange membrane 312 and the outer gas exchange membrane 313 in this way, a gap is not formed between the inner gas exchange membrane 312 and the outer gas exchange membrane 313, so that dust particles from the outside are removed from the inner gas. It is possible to prevent the invasion of the space surrounded by the exchange membrane 312. Further, the inner gas exchange membrane 312 and the surrounding body 308 are similarly overlapped with each other by having a constant length in the height direction, for example, a length of about 20 cm, so that the inner gas exchange membrane 312 and the surrounding body 308 are similarly overlapped. No gaps are formed between them, so that it is possible to prevent dust particles from the outside from entering the space surrounded by the inner gas exchange film 312. It can be detachably fixed to 4. An outer gas exchange membrane 313 is attached to the side surface of the curtain rail 311. The outer gas exchange film 313 is provided so as to overlap with the inner gas exchange film 312 within a certain height range, for example, about 30 cm below the curtain rail 311. By overlapping the inner gas exchange membrane 312 and the outer gas exchange membrane 313 in this way, a gap is not formed between the inner gas exchange membrane 312 and the outer gas exchange membrane 313, so that dust particles from the outside are removed from the inner gas. It is possible to prevent the invasion of the space surrounded by the exchange membrane 312. Further, the inner gas exchange membrane 312 and the surrounding body 308 are similarly overlapped with each other by having a constant length in the height direction, for example, a length of about 20 cm, so that the inner gas exchange membrane 312 and the surrounding body 308 are similarly overlapped. No gaps are formed between them, so that it is possible to prevent dust particles from the outside from entering the space surrounded by the inner gas exchange film 312.
We prototyped a prototype of this highly clean cot system. Figure 57A shows a bed (corresponding to a cot) installed in a normal room. FIG. 57B shows a state in which the inner gas exchange membrane is hung using a storage box installed on the upper side wall of the room to cover the entire bed. The hem of the inner gas exchange membrane is in contact with the floor, and a weight is placed to prevent the inner gas exchange membrane from turning over. A stand is placed on the floor between the inner gas exchange membrane and the bed, and a fan filter unit is installed on it. In this case, the outer gas exchange membrane is not installed. A dust counter is installed between the inner gas exchange membrane and the bed.
FIG. 58 shows the results of measuring the number density of dust particles inside the inner gas exchange membrane in the prototype of the highly clean cot system shown in FIG. 57B. As shown in Fig. 58, the dust fine particle number density decreased from the initial value of 210,000 [1 / cf] to about 1300 [1 / cf] after 40 minutes, reducing the dust fine particle number density to about 1/160. I can make you. It is clear from the results of FIGS. 11 and 12 that the cleanliness can be further improved by improving the airtightness by increasing the contact area between the bed and the inner gas exchange membrane.
[Example 4 of sleeping situation detection system] Similar to Example 1 of the sleeping condition detection system, the third sleeping experiment was performed in the tent-shaped structure shown in FIGS. 46A and 46B, and the dust fine particle density was measured. This third bedtime experiment was conducted from October 23 to October 24, 2014, about 6 months after the second bedtime experiment. The results are shown in Figure 59A. As shown in Fig. 59A, there are times when the total number of particles with a particle size of 0.5 μm or larger is stable in the single digit range (US 209D). Achieved high cleanliness of class 10 or higher, and achieved a cleanliness that is an order of magnitude higher than that of a hospital operating room or sterile room), and the cleanliness is roughly 100 times higher than that of Example 1 of the sleeping condition detection system. doing. This was achieved with three prescriptions. That is, 1) it is a 100% circulating feedback system, and 2) the S of the n = Sσ / γF molecule thus obtained is made to be the inner surface area of the closed space (if there is a leak path connecting the inside and outside, Since the internal surface area component of the space where the tent is installed enters this S, the situation of becoming hard is eliminated), and 3) σ is reduced (the internal surface area of the closed space is exposed to the closed space). Since it also includes the surface area of each part of the FFU, it is important and effective to clean this part to reduce the rate of dust spillage per unit area and unit time). In order to eliminate the leak path, it is effective to put a weight on the base of the tent-like structure from the outside and bring it into close contact with the floor, but in a closed space, it is not possible to put such a weight. With difficulty. Therefore, it is important to improve the adhesion between the foot of the gas exchange membrane 26 that constitutes the tent-like structure and the closed space inside. By wrapping the base of the gas exchange membrane 26 that constitutes the tent-like structure under the mattress, this adhesion is improved by using the bedding (futon) used at bedtime and the weight of the sleeper himself. Cleanliness above US 209D Class 10 shown in 59A was achieved (note that this technique can be performed inside a closed space). The direction of the airflow by the FFU is set so that it does not flow so as to hit the surface of the surrounding body, that is, the tent-like structure, but flows along the surface. In addition, a linear plot of the correlation amount calculated using the autocorrelation function for this time series data is shown in FIG. 59B. The inset of Figure 59B is its logarithmic plot. As the cleanliness improved 100 times, the number of background dust was reduced to 1/100, and as shown in the illustration, the peak to valley ratio of the autocorrelation function became about 2 digits, τ. 125 min. A repeating structure in the characteristic τ-Hypnokineogram was also found in. In the future, it is expected that medical and long-term care information comparable to electrocardiograms and electroencephalograms can be extracted by converting them into big data and analyzing the accumulated data.
Although the embodiments and examples of the present invention have been specifically described above, the present invention is not limited to the above-described embodiments and examples, and various modifications based on the technical idea of the present invention. Is possible. For example, the wall 9 shown in this embodiment is not necessarily limited to the side wall of the room 1, and may be a part of a ceiling wall or a floor wall. Further, the wall 9 may form a part of the multi-layer structure of the gas exchange device.
Further, when the area A of the gas exchange membrane 26 calculated in this way is a value that gives an appropriate oxygen supply capacity to the main chamber 20, the gas exchange membrane 26 has the outside world (for example, the outdoor space, the corridor space, or the corridor space). When it is a tent-like structure composed of gas exchange membranes as shown in FIGS. 46A and 46B [the area of the gas exchange membrane occupying one or all of the side surface and the ceiling surface satisfies the condition of the required area described above]. May be in direct contact with the room in which this tent is placed). At this time, while maintaining a good oxygen concentration with sufficient oxygen permeability, as shown in Fig. 47, the average is less than US 209D class 1000 during sleep for about 7 hours (especially during deep sleep without turning over). You can get a good night's sleep in a good clean environment (about US 209D Class 100). In the latest results, as you can see from Figure 59A, US 209D Cleanliness of class 10 or higher is achieved. The spikes seen in FIG. 47 are caused by dust flying when turning over, etc., and the health condition of the sleeper can also be inferred from the frequency spectrum of this spike train. When used in a special nursing home for the elderly, not only the safety confirmation of the user of this highly clean room system 10 but also the deviation from the characteristics during normal sleep (since it is not an analysis based on image information etc., privacy It is possible to monitor multiple caregivers with high accuracy from a remote location (while satisfying appropriate consideration for).
Further, in the room 1, between the inside and the outside of the room 1, the air in the room 1 rotates once in 2 hours with the air from which dust has been removed by a fan / filter unit equipped with a HEPA filter or the like in advance. It is also good to introduce with the low air volume of the above, and to discharge the same amount to the outside from room 1 by another fan filter unit of the same model.
Further, the outside air introduction port 71 of the gas exchange device 80 shown above is connected to the outside air intake port 85 of the highly clean room system 10 shown in FIGS. 42, 44, and 45, and the exhaust port of the gas exchange device 80 is connected. By connecting 73 to the exhaust port 86, it can be used as a gas exchange mechanism. In this case, it is preferable that the flow rate of the inside air flowing into the gas exchange device 80 is at least one rotation of the air in the living space 6 in at least 2 hours. Further, inside the room 1 constituting the highly clean room system 10, there is an opening for taking in the inside air of the room, and after cleaning the sucked air taken in, the entire amount is returned to the inside of the room again. The outlet has a circulation feedback mechanism provided as a pair. As described above, it is also effective that the highly clean room system 10 has at least one living space (highly clean room) characterized by having two requirements of a gas exchange mechanism and a circulation feedback mechanism. This is because the three-layer structure of "outside air / membrane / inside air" in which the internal space 7 communicating with the outside world of the wall 9 is in contact with the living space 6 via the gas exchange membrane 26 is "cut out" in the room 1. It can be understood that it is "pasted" in another place such as the ceiling through the suction pipe 75, the gas flow path 83, and the like. It is desirable that this three-layer structure has a large area-to-volume ratio (total area of the membrane / device volume) as much as possible. Further, in this "pasting destination" or the "moving destination" of the functional part, the inside air return path (for example, the gas flow path 24) communicates with the living space 6, and the outside air intake / exhaust port (for example, outside air). As long as the intake port 85 and the exhaust port 86) communicate with the outside world, their relative positions with respect to the living space 6 do not matter. In other words, as long as the gas exchange capacity exists, the existence position of the three-layer structure of "outside air / membrane / inside air" does not necessarily have to exist at the outer edge of the living space 6 in contact with the living space 6. As long as the gas exchange capacity can be ensured, the place can be "moved" to an arbitrary place and set through an air flow pipe (for example, a suction pipe 75, a gas flow path 83, etc.). The total area of the gas exchange membrane 26 in the gas exchange device 80 is at least the number. By satisfying equation (15), sufficient oxygen concentration is secured for human activity inside, and by making this area as large as possible, in addition to the above, deodorization and harmful gas emission functions can be enhanced. it can. Further, as the above-mentioned opening for taking in the inside air of the living space 6 and the outlet for returning the entire amount of the sucked air taken in to the inside of the living space 6 again after the cleaning treatment, for example, FIGS. It is effective to have the structure of the intake port 23 and the outlet port 22 in the highly clean room system 10 shown in FIG. 8 or FIG. 42, FIG. 44, and FIG. 45, and most simply, the living space. A wall-mounted air conditioner or stand that communicates with the inside of 6 and installs the above gas exchange device 80, filters the entire amount of sucked air in the living space 6, and then ejects it again from the airflow outlet. It is also possible to install an alone air purifying device or a photocatalyst deodorizing device and operate them.
In addition, for example, as a structure of a constant mechanical ventilation equipment, by setting the living space to have a highly clean filter-attached air supply machine (machine) and an exhauster (machine) that are effective for ventilation, the first-class ventilation equipment It is mentioned to prepare. Further, in each of the highly clean room systems 10 shown above, as shown in FIGS. 42, 44, and 45, a small air volume fan filter with a HEPA filter having a discharge air volume that has almost no effect on the system. A pair of two units on the suction side (in) and the discharge side (out) may be provided for mechanical ventilation between the main room and the corridor, or between the main room and the outside.
In addition, the internal space of the above-mentioned room 1, which is described as a living space assuming daily life, is not limited to mere living, but includes a dust-free lacquered space or a lacquered space without fear of a decrease in yield due to dust. Needless to say, it can be used as an advanced work space such as a high-quality painting work space. In particular, when performing painting work, when using a particularly harmful organic solvent, etc., it is recommended to use a local exhaust system with a gas exchange device that does not allow dust to pass through and exchanges only gas components as described above. Desirable for safety and health maintenance.
Further, the entire amount of gas flowing out from the outlet of the fan filter unit 21 passes through the opening 23 provided in a part of the inner wall 9a, and the opening 23 and the gas inflow port to the fan filter unit 21 are airtight. If it is willing to reduce the size of the room, returning it to the fan / filter unit 21 through the gas flow path 24 that communicates with the property is a retrofit such as a bellows installed along the inner wall 9a. You may go with a duct. Further, the external space adjacent to the main room 20 can be used as the outside air introduction space. By using the gas exchange membrane 26 as the side wall 2 of the main chamber 20, it can be directly connected to the outdoor space (external space) through the gas exchange membrane 26. In this case, the outside air introduction space is a semi-infinite open space.
It is also good to install a total of two fan filter units equipped with HEPA filters in the main room 20 for the inlet and outlet, with an air volume that allows the air in the main room to make one revolution in two hours.
Room 1 is a partition wall that includes a gas exchange membrane 26 as a part, creating a completely closed space with respect to the outside world, and since there is no pressure difference between the inside and outside of room 1, cleanliness and sterility at the time of power loss A fail-safe mechanism can be built in for sexual maintenance.
The fan filter unit 21 is preferably used at the interface between the main room 20 or the living space 6 and the internal space 7, but this arrangement is not always necessary if the ultimate cleanliness is allowed to be sacrificed to some extent. A main fan is provided with a structure in which a part of the partition wall provided between the internal space 7 and the main room 20 or the living space 6 is used as a gas exchange membrane, and fresh air can be taken into the internal space 7 as long as it is satisfied. -As the filter unit 21, it is possible to use a conventional wall-mounted air conditioner as it is.
In addition, the numerical values, structures, configurations, shapes, materials, etc. given in the above-described embodiments and examples are merely examples, and different numerical values, structures, configurations, shapes, materials, etc. may be used as necessary. Is also good.
In addition, using the numerical values, structures, and configurations given in the above-described embodiments and examples, the vacuum technology and the vacuum chamber have been evacuated at one end inside, and then the internal gas environment can be freely set. In addition, in order to utilize it for thin film growth and material and device fabrication unique to a vacuum environment, according to the present invention, the airborne miclobes are temporarily reduced to zero in a predetermined space (in a microvial (microbial) environment. By (realizing a vacuum "equivalent state"), it is possible to control the microvial environment of human activity environment and living environment to the desired one. In this situation, by actively introducing superior mic robes and introducing gas phase medicines, aromas, etc., not only will new medical environments, methods, and nursing environments be realized, but also new medical and medical treatment technologies will be introduced. And services can be created and developed (see, for example, the safety confirmation method and health condition analysis method already mentioned). In particular, when administering transpulmonary drugs, a good "S / N ratio", that is, high-quality air with no "noise" such as dust and bacteria in the inhaled air (nearly zero non-drug components). Can be done with. In particular, it is also possible to perform cross-correlation analysis on positive changes in the user due to the combination of the above-mentioned microvial environment control or the above-mentioned environment without suspended radioactive substances and the above-mentioned non-contact and non-invasive unconscious sleeping conditions. It can be a base for taking effective measures in each field. If necessary, different numerical values, structures, configurations, and usages may be used.
