Therefore, although the temperature of the refrigerant flowing through the evaporator becomes high, the temperature of the circulating medium in the solar heat collecting circuit is also high, so that the heat can be sufficiently collected. Therefore, since the compressor 1 is operated at a low compression ratio, power consumption during the hot water storage operation is reduced. Therefore, when the amount of solar irradiance is large, such as in summer, electric power is required for cooling.

In this case, the temperature of the fluid flowing out of the solar heat collecting plate 11 rises and the temperature difference with the solar heat collecting plate 11 decreases, and the area of the solar heat collecting plate 11 does not effectively contribute.
Therefore, the temperature of the fluid flowing out of the solar heat collecting plate 11 is detected, the flow rate of the flow control type pump 27 is increased, the outlet temperature is reduced, and the heat collecting amount is increased by effectively using the area of the solar heat collecting plate 11. . Next, a case where the amount of solar thermal solar radiation is reduced will be described. In this case, the fluid flowing out of the solar heat collecting plate 11 flows into the solar heat radiator 10 at a reduced temperature. Therefore, the temperature of the refrigerant flowing through the evaporator 4 decreases, flows into the compressor 1, and the refrigerating ability and the heating ability decrease. Therefore, with the decrease in the amount of heat radiation in the solar heat radiator 10,
Since the outlet fluid temperature decreases less and flows into the solar heat collecting plate 11, the temperature difference from the surface temperature of the solar heat collecting plate 11 becomes small. Then, the flow rate control means 29 increases the circulation flow rate of the flow rate control type pump 27 so as to control the outlet temperature of the solar heat radiator 10 and the fluid inlet temperature of the solar heat collecting plate 11 to increase the heat collection amount. Therefore, in response to the change in the amount of solar radiation, the flow rate is controlled so that the circulating water temperature of the solar heat collecting plate is constantly lower than the solar heat collecting plate temperature and a predetermined temperature difference. A highly reliable system that collects heat is realized.

In this case, the temperature of the fluid flowing out of the solar heat collecting plate 11 rises and the solar heat radiator 10
Flows into Therefore, the temperature of the refrigerant flowing through the evaporator 4 increases, and the refrigeration capacity and the heating capacity increase. Then, since the outlet fluid temperature of the solar heat radiator 10 decreases and flows into the solar heat collecting plate 11, the amount of heat collection further increases. For this reason, it is detected that the fluid inlet temperature of the solar heat collecting plate 11 has decreased and the temperature difference with the surface temperature of the solar heat collecting plate 11 has increased, and the compressor 1 is operated at a reduced operating frequency,
High efficiency operation is performed by lowering the refrigerating capacity and raising the temperature of the refrigerant flowing through the evaporator 4. Next, the case where the amount of solar radiation or the outside air temperature is low will be described. In this case, the temperature of the fluid flowing out of the solar heat collecting plate 11 is lowered to reduce the temperature of the solar heat radiator 10.
Flows into Therefore, the temperature of the refrigerant flowing through the evaporator 4 decreases and flows into the compressor 1. Therefore, the refrigerating capacity and the heating capacity decrease, and the outlet fluid temperature of the solar heat radiator 10 rises, flows into the solar heat collecting plate 11, and the amount of heat collection further decreases. For this reason, it is detected that the fluid inlet temperature of the solar heat collecting plate 11 has risen and the temperature difference from the surface temperature of the solar heat collecting plate 11 has become small, and the compressor 1 is operated at an increased operating frequency to perform refrigeration capacity. Increase the heating capacity and perform high capacity operation. Therefore, a hot water supply heating amount corresponding to the amount of solar radiation and the outside air temperature and a high efficiency operation are realized. In addition, since it is possible to prevent an abnormal increase in the high pressure of the refrigerant circuit that occurs when the amount of solar radiation and the outside air temperature are high, the reliability of the device is improved.
