Abstract

PURPOSE:To obtain hot water, by a method wherein a substance which is easily evaporated by the heat of solar radiation and is hardly frozen at a normal low temperature of the outside air is used as a heat-transmitting medium, the medium is evaporated by the heat of solar rasdiation, and the heat of condensation generated by the evaporated medium is utilized. CONSTITUTION:When heat-collecting pipes 41, 42... and fins 51, 52... of a heat collector 1 are heated by irradiation of solar heat, flon F-11 charged as a heat- transmitting medium in a part of the interiors of a liquid-storing part 2 and the heat-collecting pipes 41, 42... is evaporated, and a heated gas flows upwards into a condensing part 6. In the condensing part 6, the evaporated flon F-11 is condensed to a liquid by cooling with water circulating through a heat-exchanging tube 11, and the liquid is returned into the liquid-storing part 2 through a return pipe 10. Thus, a circulation cycle involving the evaporation and the condensation of the flon F-11 is formed. Accordingly, since the coefficient of heat transfer at the time of condensation of trichlorofluoromethane in the condensing part 6 is extremely high, water in the tube 11 is provided with a large amount of thermal energy and is converted into hot water.

大きなものを必要としていた。One of the ways to obtain hot water as a heat source for air conditioning equipment or hot water for hot water supply is to use a heat collector that absorbs solar radiant heat to produce hot water. Conventionally, such heat collectors have used water as a heat medium, resulting in poor heat absorption efficiency and requiring a large volume.

。Moreover, when the outside temperature drops below 0°C, such as at night during winter, there is a risk that the water will freeze and destroy the heat collection pipes. There are two ways to prevent freezing, such as: - Draining the water from the heat collection pipes when the outside temperature is close to freezing, and - Mixing antifreeze into the water. Not only is there a need for a way to detect when the water is near and drain the water, but due to the structure of the heat collection pipes, they are bent, making it impossible to completely drain the water and eliminate the risk of freeze damage. . In addition, method (2) does not have the disadvantages of method (2), but since the water containing antifreeze cannot be used as hot water for hot water supply, it is necessary to obtain hot water through a heat exchanger, and this heat The exchanger was large and had poor heat transfer efficiency.

It vaporizes due to heat, and uses the thermal energy generated when the vaporized heat medium liquefies to obtain hot water in a heat exchanger.

Since a return pipe for returning the heated heating medium to the liquid storage part is provided separately, the circulation of the heating medium is natural and smooth. Therefore, the efficiency of heat exchange in the heat exchanger in the condensing section is extremely high. Furthermore, since the heat transfer coefficient when the heat medium changes from gas to liquid is extremely high, the surface area of the heat exchanger in the condensing section can be small. Therefore, the volume of the condensing section of the heat collector can be made as small as possible. Furthermore, it has excellent effects such as requiring a small capacity pump for the water system on the heat exchanger side.
