Next, the operation will be explained. During cooling, the concentrated solution in the heater 2 is heated by the heating source 111'i and separated into a refrigerant gas and a dilute solution in the separator 8. Since the solenoid valve 10 is closed and the solenoid valve 11 is opened, the refrigerant gas is sent to the condenser 4, where it is cooled and liquefied. Since the solenoid valve 20 is closed, the liquid refrigerant is depressurized by the expansion valve 12, the solenoid valve 17 is closed, and the solenoid valve 14Vi is open, so the evaporator 5++5r'c evaporates, and the latent heat of evaporation cools the liquid refrigerant. Do this. On the other hand, since the solenoid valve 22 is closed, the dilute solution exchanges heat with the concentrated solution in the heat recovery heat exchanger 9, is depressurized by the throttle valve 15, and is then transferred to the evaporator 51T52.
It absorbs the refrigerant gas that has evaporated and generates all the absorption heat.

On the other hand, during heating, the refrigerant gas separated by the separator 8 is transferred to the solenoid valve 11.
, 14.21 are closed and the solenoid valves 10, 17, 20. It works as an evaporator and pumps up the latent heat of vaporization of the liquid refrigerant. After passing through the solenoid valve 22, the dilute solution is depressurized at the throttle valve 15 and mixed with the evaporated refrigerant gas. After releasing absorbed heat at the evaporator 52, the dilute solution is liquefied, passes through the solenoid valve 17, and enters the solution tank 2. The dilute solution is recovered, pressurized by the solution pump 8, and passed through the heat recovery heat exchanger 9. At this time, the dilute solution flows through the electromagnetic valve 22, so it is sent to the heater 2 without heat recovery. In this way, heating is a heat pump cycle that uses the condensation heat and absorption heat of the refrigerant.

Next, the operation will be explained. The refrigerant gas separated and generated in the separator 8 during cooling is heat-recovered together with the dilute solution into a concentrated solution in the heat recovery heat exchanger 9. The refrigerant gas is sent to the condenser 4, and the dilute solution is depressurized by the throttle valve 15. The operation is the same as the conventional example. In addition, during heating, only the dilute solution circuit of the heat recovery heat exchanger 9' forms a bypass with the solenoid valve 22, so that the concentrated solution pressurized by the solution pump 8 and the refrigerant gas separated from the separator 8 are used for heat recovery heat exchange. This differs from the conventional example in that heat is recovered in the vessel 9', but the other functions are the same.
