Greenhouse

The invention refers to agriculture, in particular to solar-heated series.

Currently, the installation for heating the greenhouse [1] with solar heat is known, which confines solar water heater - heat radiator, water tank for accumulating solar heat, vessel for water expansion and maintaining the required water level, connected between them with pipes. , which form о closed, circulated reef, through which the heat carrier - water circulates, and in a conduit of the circular reef is installed о electric water pump, powered by the solar battery, to increase the flow of water in the installation refinery depending on the heat of the sun's rays, so also the degree of water heating in the solar water heater.

The installation known for heating the greenhouse works in the following way: during the day the solar water heater (which is a flat tank) the sun's rays heat the water in it. The water dilates, becomes easier, rises up, circulates in the refinery of the installation according to the thermosyphonic principle, passes through the water tank, releases heat until the temperature is balanced, heats the water in it, from where heat from solar origin accumulates. At the same time, under the influence of the solar rays in the solar electric battery, an electric current is formed which starts the water pump, the water circulation is intensified in the installation refinery and in the water tank more heat is accumulated. During the night in the greenhouse, the air is cooled, the solar heater becomes a heat radiator that heats the interior of the greenhouse, in the flat vessel of the solar heater the water cools, becomes heavier, is let down, circulates in the refea following the same thermosyphonic principle, but in the direction conversely, it carries heat from the tank with water accumulated during the day in the solar water heater - at night it becomes a heat radiator, it releases heat and circulating it warms the interior of the greenhouse.

The installation known for heating the greenhouse, although it has a high economic efficiency, but in exceptional cases, when for several days it is sunny with low temperature the solar heat accumulated in the water tank is exhausted, the plants grown in the greenhouse are subject to the throat, which causes large loss.

The present invention solves the problem of ensuring the heating of the greenhouse in any weather conditions.

The essence of the invention consists in the fact that the greenhouse contains a water heater, a water tank for heat accumulation, a tank for expansion, a water pump, a solar battery, joined by pipes and installed inside the greenhouse. The greenhouse further confines a basement connected with its interior by air ducts, in which shafts are installed. In exceptional cases (sockets) the air ducts are in the open position. When the solar heat accumulated in the water tank is depleted and the air temperature in the greenhouse is lower than the air temperature in the basement, the air in the greenhouse is let down, passes through some pipes in the basement, warms up, at the same time the warm air in the basement rises. through other pipes in the greenhouse, it releases heat, warms the interior of the greenhouse, circulates according to the thermosyphonic principle and in exceptional cases the greenhouse is heated with underground heat.

The result is an increase in the efficiency of temperature regulation in thirsts for any weather conditions.

The invention is explained with the help of the figure, in which the section of the greenhouse is shown.

The greenhouse contains solar water heater (night heat radiator) 1, water tank for heat accumulation 2, tank for water expansion and maintaining its required level 3, connected to each other by water pipes 4, 5, 6 forming о refea circulated, in one of the pipes is installed о electric water pump 7 connected to the solar battery 8, and the greenhouse also includes a basement 9, which communicates with the interior of the greenhouse through the air pipes 10 and 12 with screws 11 and 13.

The heating of the greenhouse is carried out as follows.

During the day in the solar heater 1 the water heats up from the sun's rays, dilates, becomes lighter, rises upward, passes through the pipe 5 into the pipe 4, releases some of the heat, passes into the tank 2, releases the rest of the heat , until the temperature of the water is equalized, it passes through the pipe 6 in the solar heater 1, again it warms up, it circulates in the refinery of the installation for heating the greenhouse according to the thermosyphonic principle, it takes the heat captured by the solar heater 1 in the tank 2, where о releases, the water heats up in it and in tank 2 the heat accumulates; at the same time the solar rays also heat the solar battery 8, in which the solar energy is transformed into electrical energy, it supplies electricity to the electric water pump 7 which pumps the water in the refea in the direction in which the water circulates according to the thermosyphonic principle, intensifies the circulation of the water in the refea the installation for heating the greenhouse according to the heat of the solar rays; during the night in thirst the temperature drops, the solar water heater 1 becomes a heat radiator, in which the water cools, the water becomes heavier, it is let down, it circulates in the refinery of the greenhouse heating installation, following the thermosyphonic principle, but in the opposite direction , from the radiator 1 passes through the pipe 6 into the tank 2, where it is heated by the heat accumulated during the day, passes through the pipes 4, 5 again into the radiator 1, releases the heat, heats the interior of the greenhouse, and in the cases of heat exhaustion in the tank 2, the blades 11 and 13 are opened, the cold air from

MD 1956 C2 2002.07.31 the interior of the greenhouse is let down, it passes through the pipes 12 in the basement, it is heated with underground heat, it rises up, it passes through the pipes 10 inside the greenhouse, it releases the heat, it circulates according to the thermosyphonic principle and it warms up the interior of the greenhouse. with underground heat.

Embodying the present invention ensures the preservation and normal development of plants grown in the greenhouse, 5 growing a rich fruit crop without heating the greenhouse with fuel, guarantees high economic efficiency even in adverse climatic conditions.
