In the same figure, reference numeral 1 denotes an exhaust fan 3 and an internal fan, which are successively connected to form a cooling/heating heat pump circuit A. A refrigerant circuit is branched from this cooling/heating heat pump circuit via a solenoid valve 17a, and a heat storage tank 11 is connected. A heat pump supply circuit B includes a heater 13 that exchanges heat with the fluid 12' in the heat pump 12' using the condensation heat of the refrigerant. 15b is a radiator, which is blown and cooled by a dedicated fan 15a, and is connected in series between the heat exhaust device 14 and the engine 1 on the downstream side of the heat exhaust device 14 via a three-way solenoid valve 16 in this exhaust heat recovery circuit C. It has been inserted. This is to prevent the engine 1 from overheating.The more it does not exchange heat with the fluid in the heat storage tank 14, the more the temperature of the fluid 12 increases by 1-1, and the temperature of the cooling water that should cool the engine 1 increases. When the temperature rises, the three-way valve 16 is switched to transfer the cooling medium to the radiator 1.
The exhaust heat collected from the engine 1 and the exhaust gas heat exchanger 2 by flowing to the 5b side is radiated to the atmosphere or the like.

In A, during cooling, a refrigerant (not shown) is caused to flow as indicated by the solid arrow line, so that the outdoor heat exchanger 7b acts as a condenser, and the indoor heat exchanger 8b acts as an evaporator. The refrigerant exiting the outdoor heat exchanger 7b passes through the solenoid valve 1.
4, some of the condensate accumulates in the liquid reservoir 9, but then flows through the cooling pressure reducer 11 to the indoor heat exchanger 8b, passes through the check valve 13b, and finally reaches the compressor 1. Return to

7 The temperature of the fluid 25 that can be heated in the vessel 17 is about 55°C due to the pressure conditions of the refrigerant, but the temperature of the fluid 25 obtained in the heat exhauster 22 in the exhaust heat recovery circuit C is about 85 to 90°C. be. The fluid 25 heated by the heater 17 is
It is further heated by a heat exhauster 22. During cooling operation, when the temperature of the fluid 25 in the heat storage tank 24 rises in the exhaust heat recovery circuit C, it becomes difficult for the cooling water to exchange heat with the fluid 25 in the heat exhaust device 22, and further 22
Population cooling water temperature increases. If the temperature of the cooling water returning to engine 1 exceeds a certain set value, liquid pump 1
0 is operated to send the condensate, and the refrigerant heater 20 vaporizes it using engine exhaust heat. The high-pressure gaseous refrigerant is mixed with the discharge gas of the compressor 5, and the outdoor heat exchanger 7b converts it into condensation heat. Abandon it.
