る。These systems heat hot water directly or indirectly using solar heat, but this is inevitable because solar energy is rare and as the temperature of the heat collection medium increases, the heat collection efficiency decreases. In order to increase heat collection efficiency, heat collectors have become larger, and in order to improve heat collection efficiency, heat collectors are not only necessary, but also sufficient insulation treatment is required for circulation of heat collection media, which reduces equipment construction costs. It also has the disadvantage of being expensive.
本発明は上記従来の欠点を解消したものであり、以下、

Note that the rotation speed of the circulation pump 9 is controlled so that the temperature of the hot water at the outlet of the user-side heat exchanger 4 is always kept constant.

けた温度検知素子（図示せず）の作用により、 。In the above configuration, the operation will be explained. During heat collection operation, the refrigerant compressor 3 and circulation pump 9 operate. Therefore, the refrigerant gas compressed to a high temperature by the refrigerant compressor 3 flows into the refrigerant passage 4'a of the user-side heat exchanger 4, and flows into the hot water supply passage 4b of the user-side heat exchanger 4 by the action of the circulation pump 9. Provides heat to the water supplied to the lower floors. The heated water flows into the upper part of the hot water storage tank 8 and is stored therein. On the other hand, after the refrigerant heat released to the hot water supply is liquefied, it is subjected to the action of throttling 9 in the expansion valve and becomes low temperature, and passes through the connecting pipe 7b to the heat source side heat exchanger 1, which is composed of fin tubes and has a black coating on its surface. The refrigerant flows into the refrigerant compressor 3, absorbs solar heat and outside air heat, evaporates into gas, and flows into the refrigerant compressor 3 through the connecting pipe 7a, repeating an evaporative compression cycle. As a result, the temperature of the water in the hot water storage tank 8 is gradually increased, and the water is stored in the hot water storage tank 8. Note that when all of the water in the hot water storage tank 8 reaches the set temperature, a temperature detection element (not shown) provided at the inlet side of the circulation pump 9 acts as follows.
冷媒圧縮機３、循環ポンプ９は停止され、集熱運転を停
止する。The refrigerant compressor 3 and the circulation pump 9 are stopped, and the heat collection operation is stopped.

連結した構成としたことによ９次の如き効果がある。As is clear from the above embodiments, the present invention connects a heat source side heat exchanger, a refrigerant compressor, a user side heat exchanger, and an expansion valve in sequence to constitute a vapor compression cycle using a refrigerant as a working fluid, and The heat exchanger on the side heat exchanger is a refrigerant evaporator, and the heat exchanger on the user side releases the heat absorbed into the hot water supply to form a hot water supply device.The heat exchanger on the heat source side is a fin-tube type and the surface is painted black. A film is formed to have solar heat absorption ability and atmospheric heat absorption ability, and a heat collection unit consisting of a heat source side heat exchanger, a refrigerant compressor 3, a user side heat exchanger 4, and an expansion valve φ. The system has a three-unit configuration consisting of a circulator unit consisting of a circulator unit and a hot water storage unit consisting of a hot water storage tank, and each unit is connected by refrigerant piping and water piping, resulting in the following effects.
（１）熱源側熱交換器を流動する冷媒の温度は低温であ
り、太陽熱を有効に吸収することができる。(1) The temperature of the refrigerant flowing through the heat source side heat exchanger is low, and solar heat can be effectively absorbed.

きさは小さなものとなる。また、曇天時等、太陽熱が十
分得られない場合にも自然通風力を生かした大気熱の吸
収により、給湯運転が行なえる。In addition, since it effectively absorbs atmospheric heat, the size of the heat collector becomes small. Furthermore, even when sufficient solar heat cannot be obtained, such as during cloudy days, hot water supply operation can be performed by absorbing atmospheric heat by utilizing natural ventilation.
（２）熱源側熱交換器は大気熱をより積極的に取り入れ
るため、カバー、断熱材等は不用であることから、小型
、軽量かつ安価に製作できる。(2) Since the heat exchanger on the heat source side more actively takes in atmospheric heat, a cover, insulation material, etc. are unnecessary, so it can be manufactured in a small size, light weight, and at low cost.
（３）熱源側熱交換器と循環機ユニットを接続する配管
は低温の冷媒が流動することから吸熱作用が働くことか
ら、配管断熱は全く不要である。(3) The piping connecting the heat source side heat exchanger and the circulator unit absorbs heat due to the flow of low-temperature refrigerant, so no piping insulation is required at all.
（４）熱源側熱交換器、冷媒圧縮機、利用側熱交換器、
膨張弁を順次連結してなる蒸気圧縮サイクルはサイクル

続配管長さに制約がある。(4) Heat source side heat exchanger, refrigerant compressor, user side heat exchanger,
In order to maintain cycle stability in a vapor compression cycle in which expansion valves are connected in sequence, there are restrictions on the amount of refrigerant charged and the length of the connecting piping due to pressure loss.

ない接続距離内で設置することができる。Therefore, by configuring the three units of the heat collection unit, circulator unit, and hot water storage unit as in the present invention, the heat collection unit and the circulation unit can be installed within a connection distance that does not interfere with the vapor compression cycle.
