安くすることができる利点がある。In place of cooling systems that utilize the sensible heat of water, in recent years, ice storage type air conditioning and cooling systems have been developed that freeze water and utilize the heat released by ice to reduce the volume of the ice heat storage tank. This system uses cheap late-night electricity to operate a cold storage device at night, exchange heat between ice and circulating cold water during daytime air and H1 cooling, and then use fan coils installed indoors to exchange heat between ice and circulating cold water. It has the advantage that it can be applied to air conditioning equipment such as units, reducing operating costs.

るＣとができる。In this type of ice cold storage type air conditioning system, a cold storage device has been developed in the past. The newest cold storage device is an evaporator in a refrigeration circuit that circulates refrigerant gas and returns condensation and vaporization to achieve cooling, and a chilled water cooler that can be selectively connected to and shut off from the load circuit. There is one in which the ice heat storage tank of the circulation circuit is connected with multiple beat no. 9 tubes. In this device, ice is deposited on the surface of a heat pipe inserted into an ice heat storage tank, forming a thick layer of ice, and during cooling, cold water is passed through to melt the ice and create circulating cold water. . With this structure, compared to the one in which ice is made directly on the surface l/C of the refrigerant pipe in the refrigeration circuit, the heat nozzle and eve surface f1 can be used as an ice formation surface and can be formed wider, and there is less load fluctuation on the refrigerator. <C, which also simplifies the medium pipe line, can be achieved.
この氷蓄冷式冷房システムでは、夏期の冷房だけしか行

がある。This ice storage cooling system can only provide cooling in the summer, and a separate system must be installed for heating and hot water supply in the winter.

て２倍程度高価になるなどの欠点がおった。However, providing separate systems for cooling and heating and hot water supply increases the size of the equipment and increases equipment costs and operating costs. If you combine these into a heat pump that shares a refrigeration unit, you will need a four-way switching valve, the control circuit will be complicated, and the price will be about twice as high as that of a cooling-only refrigerator. There were drawbacks such as:

This project has developed an ice storage type cooling system that uses solar heat and heated wastewater to reduce operating costs, as well as an air conditioning system that also serves as heating and hot water supply.

1 is opened, the others are fully closed, and the second circulation circuit F and the load side circuit B are connected. The high-temperature hot water stored in the hot water tank 18 radiates heat from the water pump 22, circulates through the load side circuit B, and heats the room.

。Note that the hot water exiting the heat exchanger 27 is returned to the circulation circuit F through the valve 9n. When it is impossible to collect heat by the solar heat collector 20 (FC) due to falling rain or at night, and the temperature of the hot water in the hot water tank 18 drops to, for example, 40°C or lower, the central control unit 21 controls the temperature of the second heat collector. The circulation circuit F and the heat storage tank 3 are connected, and the refrigerant circuit C, the third circulation circuit G, and the load circuit B are operated.In this case,

Ｋ勇かハて、室内の暖房が行われる。The heat pie f6 connecting the heat storage 1I9J3 and the evaporator 2 absorbs heat from the hot water and heats the refrigerant in the evaporator 2. In this case, even if the temperature of the hot water in the heat storage tank 3 is 20°C, by making it lower than the refrigerant evaporation temperature inside the evaporator 2, the temperature of the hot water taken out from the condenser 14 will be 40°C.
The temperature can reach up to 50℃. This is also known from the principle of heat pump refrigerators. Therefore, the warm heat exchanged in the evaporator 2 is circulated through the refrigerant circuit C by the action of the compressor 130, and is exchanged with hot water passing through the third circulation circuit G inside the condenser 14. 3rd place for heat exchange
The hot water flowing through the circulation circuit G is heated to, for example, 50°C, and is passed through the water pump 23 and the valve 9h to the load side circuit B.
The room is heated by K.
