A conventional refrigeration system will be explained with reference to FIG. 1 is a compressor, 2 is a four-way valve, 3 is an indoor heat exchanger, 4 and 5 are pressure reducers, 6
is an indoor heat exchanger. During cooling operation, the refrigerant flows as shown by the solid line. The refrigerant is adiabatically compressed by the compressor 1 until it reaches a high temperature and high pressure state, radiates heat in the outdoor heat exchanger 3, becomes a saturated liquid, undergoes an isenthalpic change in the pressure reducer 5, decreases both pressure and temperature, and becomes wet steam. Become. In addition, the indoor heat exchanger 6
This is a refrigeration cycle that operates so that it absorbs heat and becomes dry steam. Also, during heating operation, the refrigerant flows as shown by the broken line. This is a refrigeration cycle in which the refrigerant is switched by a four-way valve 2 and flows in the opposite direction, radiates heat in an indoor heat exchanger 6, is throttled in a pressure reducer 4, and absorbs heat in an outdoor heat exchanger 3. According to a refrigeration system having such a refrigeration cycle, the heat radiation of the outdoor heat exchanger cannot be used during cooling operation, or only the heat of the outdoor air can be recovered by the heat pump during heating operation. Furthermore, since heat exchange is performed between the refrigerant and the outdoor air through forced heat transfer by the blower, there is a drawback that the power consumption of the outdoor blower cannot be saved.

In the above-mentioned refrigeration cycle, the solenoid valve 7 is closed during cooling operation 8.
By opening ゜lO, high temperature and high pressure refrigerant flows through the bypass pipe 12.
The liquid flows into a saturated liquid through natural convection heat transfer with the cold water in the heat exchanger 9 in the water tank, becomes a saturated liquid, undergoes an isenthalpic change in the pressure reducer 5, decreases both pressure and temperature, and becomes wet steam, which releases indoor heat. The exchanger 6 absorbs heat. When the cold water is heated to a certain temperature, the solenoid valve 810 is closed, the solenoid valve 7 is opened, and a conventional cooling operation is performed in which heat is radiated by forced convection heat transfer in the outdoor heat exchanger 3.

Also, during heating operation, by closing the solenoid valve 7 and opening 8.10, the moist saturated steam flows to the bypass pipe 12, and the heat exchanger 9 in the water tank absorbs the heat of the hot water by natural convection heat transfer, turning it into fresh steam. Then, the process returns to compression 4#11. When the hot water has cooled to a certain temperature, the solenoid valves 8 and 10 are closed and the valve 7 is opened to perform a conventional heating operation in which heat is absorbed by forced convection heat transfer in the outdoor heat exchanger 3. However, natural convection heat transfer between the liquid and refrigerant in the water tank heat exchanger 9 has a better heat transfer coefficient than forced heat transfer between the air and the refrigerant in the outdoor heat exchanger 3, making it possible to stop operation of the outdoor blower. .
