【考案の詳細な説明】
本考案は、太陽熱を利用して少なくとも冷房を
行えるようにした太陽熱利用装置に関する。[Detailed Description of the Invention] The present invention relates to a solar heat utilization device that can perform at least air conditioning using solar heat.

ンニングコストが高くなるなどの欠点があつた。 In this type of solar heat utilization device, when the heat collection exceeds the load, the temperature of the heat medium in the heat collection circuit rises and the heat medium boils. If it boils, the internal pressure in the circuit will rise, creating a steam hammer and damaging equipment, which is dangerous. For this reason, conventional methods include installing a dedicated heat exchanger to prevent boiling and exchanging heat with cooling water from a cooling tower to radiate heat, or passing city water through the heat exchanger instead of cooling water and discharging it. I was taking it. However, a heat exchanger is required separately, and the former requires the addition of a pump and three-way electric valve, which increases the initial cost, while the latter requires wasteful discharge of city water, which increases running costs. There were drawbacks such as being expensive.

The next side heat storage tank 13 is connected. 14 is a pump that circulates the heat medium in the tank 13 to the load 15, and 16 is a pump that cools the refrigerator 10 with water from the cooling tower 17. 18 is a hot water storage tank connected to the heat exchanger 8 through a circuit having a pump 19. Further, 20 is a control device for preventing boiling of the heating medium, which detects temperature sensors 21 and 21' that detect the temperature of the upper part of the surge tank 4 and the outlet pipe of the heat collector 2, and the temperature of the heat storage tank 13. It operates by a temperature sensor 22.

Cold water is stored in the tank 13 and sent to the load 15 for cooling. Further, the heat transferred by the circuit 9 is stored as hot water in the hot water storage tank 18 via the heat exchanger 8 and is used for hot water supply.

Heat is radiated to the next side heat storage tank 13 and the temperature of the heat storage tank 13 is raised, thereby lowering the temperature on the heat collection side. Eventually, heat storage tank 1
3 rises and the temperature detected by the temperature sensor 22 exceeds the set value, the control device 20 then drives the pumps 5, 12, 16 and switches the switching valve to remove the collected heat. is directly sent to the refrigerator 10 and radiated by the cooling tower 17, and cold water generated by the refrigerator is put into the secondary heat storage tank 13 to lower the temperature of the heat storage tank 13. In this way, by repeatedly heating and cooling the secondary heat storage tank 13, excess heat can be absorbed and overheating of the heat collection circuit can be prevented.
