Adsorption type freezer

[Detailed Description of the Invention]

(Field of the Invention] The present invention relates to an improvement of the adsorption type freezer constituted to heat pump using the exothermic endothermic phenomenon accompanying the adsorption desorption reversible reaction of the refrigerant to adsorbent. [Description of the Prior Art] Although the cogeneration system which aims at the optimal balance of the electricity demand in a building and various equipment provided with the private power generator and heat demand attracts attention these days, it is in that case, The electric power of Hourly and the correspondency of heat must be detected and it must constitute to the system which introductory energy can use most effectively, 0 for which to collect the exhaust heat which changes intricately according to the operation situation of an engine or a turbine for that purpose with sufficient flattery nature is needed, for example, Or, -- it has become common to manufacture the cold water for air conditioning from exhaust heat [ like ], and an absorption refrigerating machine is usually used for this. However, as for an absorption refrigerating machine, there is a problem in the standup characteristic, and one problem has the flattery nature to the temperature change and quantitative alteration of a heat source or cooling water now. For this reason, its attention came to be paid to the adsorption type freezer which has arranged the solid absorbent in a vacuum system. This adsorption type freezer is an organization which generates cold heat by making hot exhaust heat etc. into a heat source using exothermic Endotherm at the time of refrigerants, such as water, carrying out adsorption desorption to solid absorbents, such as silica. A heat exchanger which functions as an adsorbent heat exchanger, an evaporator, or a condensation machine in a high vacuum container of a sealing system is arranged, and it is constituted so that an adsorption process and a desorption (reproduction) process may be repeated. This adsorption type freezer rises compared with the absorption refrigerating machine using absorption liquid, and has the feature that a sex is good and the flattery nature to change of a heat source, or circulating water temperature and quantity is good. [Problem(s) to be Solved by the Invention] the conventional adsorption type freezer -- 2 -- the -- main -- the adsorbent heat exchanger which is base was a shell and tube type heat exchanger. that is, it was filled up with adsorbent in shell, and also actual arrangement of many tubes for delivering and receiving heat to adsorbent is carried out into shell, and a heat carrier (warm water or cooling water) is dipped from the exterior in this tube -- there was thing 7. For this reason, the whole device became big from the heat transfer area contained per unit volume having a limit inevitably. That the heat transfer area per unit volume is small had a limit also in standup nature and flattery nature, and there was a problem also in fully pulling out the feature of an adsorption type freezer. therefore, the place made into the object of the 1 present invention -- Or -- the problem of the conventional adsorption type freezer [ like ] is solved, and it is compact and is in providing the good adsorption type freezer of a response. Constitution] of [invention The first function part that the present invention has arranged the heat exchanger which functions on the vacuum airtight interior of a room as a condensation machine or an evaporator, and the adsorbent heat exchanger, and also encloses a refrigerant indoors, The second function part that the heat exchanger which functions on the vacuum airtight interior of a room as an evaporator or @ Condenser, and the adsorbent heat exchanger have been arranged, and also encloses a refrigerant indoors, The first liquid-sending pipeline of the expansion valve infixation which turns to the evaporator surface of the second function part the refrigerant liquid condensed on the condensation machine surface of the first function part, and sends the liquid, In the adsorption type freezer which consists of the second liquid-sending pipeline of the expansion valve infixation which turns to the evaporator surface of the first function part the refrigerant liquid condensed on the Cohesive instrument surface of the second function part, and sends the liquid, The adsorbent heat exchanger of the first above-mentioned function part and the second function part consists of a plate type heat exchanger which equipped the surface with adsorbent outside the hollow plate, and supplies a heat carrier from the outside of a system in the hollow plate of this plate type heat exchanger. In that case, adsorbent also constitutes the heat exchanger with which it is loaded between the fins formed in the surface of a plate type heat exchanger and which functions as the condensation machine or evaporator of the first function part and the second function part by a plate type heat exchanger. The first liquid-sending pipeline and the second liquid-sending pipeline connect a condensation liquid receptacle and a liquid-sending termination to a liquid dispersion nozzle for those liquid-sending start edges, and a liquid dispersion nozzle is installed above the heat exchanger which functions as a condensation machine or Scoliot again under the heat exchanger on which this condensation liquid receptacle functions as a condensation machine or an evaporator. When water can be most ordinarily used as a heat carrier enclosed with a function part and this water is used as a heat carrier, zeolite, Silica Kel, a sodium sulfide, a sodium bromide, quicklime, etc. can be used as a solid absorbent. moreover -- as a heat carrier -- A use Budget, such as ammonia, -- as adsorbent, for example, iodine sodium, a nickel chloride ammonia complex, etc. can be used in this case. [Example] The example shown in the drawing is described below. Inside of cylindrical shell l which Drawing 1 is what showed the important section section of the adsorption type freezer according to the present invention, and one both ends closed, Partition 2 which passes along a central axis divides into two airtight chambers 3 and 4, and it is composition Room to be about the first function part in airtight chamber 3. The present invention example made into A room (it is hereafter called the second functional room 4) which constitutes the second function part for airtight chamber 4 again (for it to be called [ hereinafter, ] The-functional room 3) is shown, and although Drawing 2 is the same section as Drawing 1, in the case of Drawing 1, the situation where the direction of a flow of the refrigerant is reverse is shown. In 5 The-functional room 3, it is with adsorbent heat exchanger 5 (it is hereafter called the first adsorbent heat exchanger 5) so that it may be seen in the 1~2nd figure, Heat exchanger 8 (same.) which heat exchanger 6 (it is called same and the first heat exchanger 6) which functions as a condensation machine or an evaporator is arranged, and similarly functions on the second functional room 4 as adsorbent heat exchanger 7 (it is called the 5 second adsorbent heat exchanger 7), and an evaporator or a condensation machine the second heat exchanger 8 -- calling -- it is arranged. The first adsorbent heat exchanger 5 and the second adsorbent heat exchanger 7 have the same structure, All are the plate type heat exchangers installed along the direction of an axis of shell l in shell (inside of The-functional room 3 and the second functional room 4) in a majority of plates with adsorbent which made the surface equip with adsorbent 10 outside hollow plate 9 while adjoining mutually. Both ends of each hollow plate 9 are connected to a header (not shown) provided in both ends of shell 1. A heat carrier is supplied in each hollow plate 9 from a rudder to that [ one ], and after passing through inside of each hollow plate 9, it flows into ragout to that of another side. Although adsorbent 1o with which the surface is equipped outside hollow plate 9 is adsorbent of the solid like zeolite or silica gel like previous statement and the mounting mechanism is explained in full detail in the after-mentioned 3~5th figure, The gap of a fin established in the surface outside hollow plate 9 is loaded, the surface is pressed down using a porous board or rope, and it is held in the gap. It is the plate type heat exchanger installed along the direction of an axis of shell 1 in shell (inside of The-functional room 3 and the second functional room 4), the first heat exchanger 6 and the second heat exchanger 8 which function as a condensation machine or an evaporator also having the same structure mutually, and adjoining mutually in a majority of hollow plates 11. it is connected to the header (not shown) provided in the both ends of shell 1, and one side of the both ends of each hollow plate 11 is strange -- good or a heat carrier is supplied in Each hollow plate 11, and after passing through the inside of each hollow plate 11, it is discharged good strangely [ another side ]. Under the first heat exchanger 6 and the second heat exchanger 8, condensation liquid receptacle 12.13 is installed, respectively, and fluid collection of the refrigerant liquid condensed on the surface outside these heat exchangers 6.8 is carried out. Liquid dispersion nozzle board 14.15 for distributing equally on the vessel surface and Dispersion(ing) refrigerant liquid on it is installed above the first heat exchanger 6 and the second heat exchanger 8, respectively. And the first liquid-sending pipeline 16 which passes to liquid dispersion nozzle 15 of the second heat exchanger 8 from condensation liquid receptacle 12 of the first heat exchanger 6, The second liquid-sending pipeline 17 which passes to liquid dispersion nozzle 14 of the first heat exchanger 6 from condensation liquid receptacle 13 of the second heat exchanger 8 is instituted, and it is in these first liquid-sending pipelines 16 and the second liquid-sending pipeline 17, Not only the example of zero the example which the first liquid-sending pipeline 16 and the second liquid-sending pipeline 17 all penetrated partition 2 in the example of 0 illustration in which expansion valve 18.19 is infixed, and all instituted is indicated to be The shell wall of The-functional room 3 and the second functional room 4 is penetrated, and a pipeline is once taken out out of shell, An electromagnetic valve is used, in order to make that opening and closing control according to the change of adsorption desorption operation and, as for expansion valves 18 and 19, to automate [ the composition in which expansion valve 18.19 is made to infix in the pipeline portion exposed out of this shell may be sufficient as ] this opening-and-closing operation anyway. The 3~5th figure is what showed the charge structure in the case of equipping the surface with adsorbent outside hollow plate 9 in the first and second adsorbent heat exchanger, and shows the example of hollow plate 9 used as a heat exchange side which forms many collateral-value-like cells 21 using a fin covering the surface area outside all mostly. Namely, the thing established for a large number in the shape of a base eye crossing mutually fin 23 of the same height prolonged in the direction which intersects perpendicularly with the surface outside both of hollow plate 9 with fin 22 prolonged in the direction of an axis, and this, Many cells 21 enclosed with fins 22 and 23 are formed, and let this cell 21 be a charge container of a solid absorbent in each. The layer of a solid absorbent with predetermined thickness will contact the external surface of plate 9, and a fin side, and will be attached to the surface outside both of hollow plate 9 by this, Since five face piece serves as a heating surface, touches adsorbent and is divided into a cell small moreover among six face pieces which form each cell, the heat exchange with the heat carrier and adsorbent which flow through the inside of hollow plate 9 becomes very good. Although not illustrated one time in all the lateral surfaces of each cell 21, a porous board or gauze is laminated, and adsorbent is held down by this breathability cover in each cell 21. Attachment of this cover is performed using frame 24 which turns around the end of fins 22 and 23. As for the thing of Drawing 3, hollow plate 9 consists of integral-moulding articles, such as metal, in the 3~5th figure, What processed the thing of Drawing 4 into the tube plate using metal plate 25.26 of two sheets, and spacer 27, and the thing of Drawing 5, By piling up the end of metal Fi25.26 of two sheets, and joining by welding, it is what showed the example used as the tube plate, and there is no change at the point which forms many cells 21 for adsorbent charge with fins 22 and 23 in any case. Drawing 6 is what showed schematically some devices of the 1~2nd figure, and the member shown in the same reference number as the 1~2nd figure is the same as the thing of the 1~2nd figure. 29.30 shows the tube plate and Hesogoo of the heat carrier which goes in and out from the outside in the plate of each heat exchanger is provided in this outside. It explains concretely, referring to the 7~8th figure corresponding to the 1~2nd figure and this for the appearance like operation LIi of the adsorption type freezer of the present invention which becomes the above composition. The state where the second heat exchanger 8 of the second condensation machine 5 functional room 4 is functioning [ the first heat exchanger 6 of The-functional room 3 ] as an evaporator in Drawing 1 and Drawing 7, In Drawing 2 and Drawing 8, the first heat exchanger 6 of The-functional room 3 shows the state where an evaporator and the second heat exchanger 8 of the second functional room 4 are functioning as a Inspection device. In this state, if the operational status of Drawing 1 and Drawing 7 is explained first, when manufacturing cold water using waste heat (for example, thermal wastewater) etc., circulation supply of the thermal wastewater will be carried out at the first adsorbent heat exchanger 5 of The-functional room 3, and it will let cooling water flow to the second heat exchanger 8, and will take out cold water. In that case, to the first heat exchanger 6 and the second adsorbent heat exchanger 7, pour heat carriers for cooling, such as cooling water, and it is Open about expansion valve 18 in the state of this Drawing 1 and Drawing 7. The refrigerant (for example, water) which closed-Into expansion valve 19 and which was sticking to the adsorbent of the first adsorbent heat exchanger 5 by this is heated by thermal wastewater, and it evaporates in The-functional room 3, and condenses the steam on the surface of the first heat exchanger 6. The Ia&IiI heat in that case is carried out out of a system with the cooling water which dips the inside of the plate of the first heat exchanger 6. Fluid collection of the condensed liquid is carried out to am liquid receptacle 12. the liquid in this Iji Condensation receptacle 12 should pass the first liquid-sending pipeline 16 -- although sent into liquid dispersion nozzle 15 by pressure difference, from liquid dispersion nozzle 15, towards the surface of the second heat exchanger 8, expansion valve 18 is passed in that case, and it becomes low pressure, and is sprayed [ it is alike and ]. The spraying liquid adhering to the surface of the second heat exchanger 8 evaporates here, and the steam is adsorbed by the adsorbent of the second adsorbent heat exchanger 7. That is, the heat of adsorption which occurs when it cools and evaporates from the cooling water dipped by the second heat exchanger 8, cold water is manufactured here and 5 adsorbent is adsorbed is carried out out of a system with the heat carrier (for example, cooling water or air) which flows through the second adsorbent heat exchanger 7. Thus, while adsorption of a refrigerant to adsorbent is performed at desorption of the refrigerant from adsorbent, and the second functional room 4 and this state is performed at The-functional room 3, The second functional room 4 becomes [ high-pressure side ] the low-pressure side, operation by which Pressure is balanced and cold water is manufactured by the second heat exchanger 8 finishes, and The-functional room 3 ranks next one, after desorption adsorption is completed soon, and it switches to the operation mode shown in Drawings 2 and 8. In operation shown in Drawings 2 and 8, expansion valve 19 is switched to Open, expansion valve 18 is switched to Closed, thermal wastewater is passed by the second adsorbent heat exchanger 7, and cold water is manufactured by the first heat exchanger 6. In that case, the heat carrier, for example, the cooling water, or air for cooling the heat of adsorption of a refrigerant to the first adsorbent heat exchanger 5 is passed, and the cooling water which takes out the heat of condensation of a refrigerant also to the second heat exchanger 8 is poured. By this, the refrigerant which was sticking to the second adsorbent heat exchanger 7 is condensed by the second heat exchanger 8, Through the first liquid-sending pipeline 17, after this condensation liquid is extracted with expansion valve 19, it is sent out to liquid dispersion nozzle 14 by pressure difference, is Dispersion(ed) by the surface of the first heat exchanger 6, evaporates here, cools the cooling water poured by this The-heat exchanger 6, and manufactures cold water. The refrigerant which evaporated is adsorbed by the adsorbent of the first adsorbent heat exchanger 5, and the heat of adsorption is carried out out of a system with the heat carrier which flows through this. These two cycles are repeated. Cold water is made by the first heat exchanger 6 and the second heat exchanger 8, and change operation is continuation-ized. The cold water of a continuation flow can be made from the thermal wastewater of a continuation flow. On the other hand, if a view is changed, a heat transfer will be performed to the second heat exchanger 8 or the first heat exchanger 6 which is functioning as a condensation machine from The-heat exchanger 6 which is functioning as an evaporator, or the second heat exchanger 8. Heat pump will be formed. If the state is held when desorption is completed at The-functional room 3 without continuation-izing change operation for example, and if the state is maintained when adsorption is completed at the second functional room, the energy state can be stored and it will function also as 1M heat plant till required time. [Effect] The adsorption type freezer of the present invention with the above composition and operation, Since a plate type heat exchanger is used especially as an adsorbent heat exchanger and the surface is equipped with adsorbent with a big heat transfer area, while desorption adsorption performance becomes high and being able to carry out small size of the device, It becomes good, the standup nature, i.e., the starting nature, which were the problems of this seed device, answers satisfactorily in short starting time, and has the special feature that continuation-ization of a cycle is performed smoothly.
