１で加熱された温水が流入し、放射用蓄熱槽１０には太
陽熱コレクタ１で放熱された水が流入することになる。When the sun shines 9 and the water temperature inside the solar heat collector 1 rises, the specific gravity of the water in the collector becomes smaller than the specific gravity of the hot water heat storage tank 4, and the hot water passes through the on-off valve 2 and the check valve 3 and is stored in the hot water heat storage tank. The water flows into the tank 4, and at the same time the water from the hot water heat storage tank 4 flows into the pipe 1a.
It flows into collector 1 through . At this time, hot water in the collector 1 does not flow into the radiant heat storage tank 10 because the check valve 11 is in the opposite direction.Next, on cloudy days or at night, the water temperature inside the solar collector 1 may be lower than the hot water in the hot water heat storage tank 4. Even if the solar heat becomes low, the check valve 3 prevents the hot water in the heat storage tank 4 from flowing back into the solar heat collector 1, so that the hot water is retained. On the other hand, when the water temperature of the solar heat collector 1 decreases compared to the water temperature of the radiant heat storage tank 10, the check valve 11
The water in the heat storage tank 10 flows into the collector 1 through the pipe 1a, and at the same time, the water in the collector 1 flows into the radiation heat storage tank 10 through the pipe 1a. Therefore, hot water heated by the solar heat collector 1 flows into the hot water heat storage tank 4, and water radiated by the solar heat collector 1 flows into the radiation heat storage tank 10.

冷水及び温水を利用して冷房と給湯（暖房）が出来る。Next, when the refrigeration system 5 is operated, cold water is produced in the cold water heat storage tank 12 in which the evaporator 9 is incorporated, and at the same time hot water is produced in the radiant heat storage tank 10 in which the condenser 7 is incorporated. Since hot water is not needed when it is stored in the hot water heat storage tank 4, the heat is radiated to the atmosphere through the solar heat collector 1 at night when there is no sun. In addition, hot water flows into the hot water heat storage tank 4 through a passage a, hot water is stored in the heat storage tank 4, cold water is stored in the cold water heat storage tank 12, and this cold water and hot water are used. Air conditioning and hot water supply (heating) are possible.
