ABSTRACT:
There are provided a water-refrigerant heat exchanger30for exchanging heat between refrigerant discharged from a compressor21and engine-cooling water circulating an engine-cooling water circuit10,prior to being fed into the radiator22,and a bypass25for guiding the refrigerant prior to being fed into the evaporator24to the water-coolant heat exchanger30while bypassing the evaporator24and the compressor21.When it is desired to accelerate the warming-up of the engine11,the bypass25is closed to operate the compressor21to heat the engine-cooling water by high-pressure refrigerant, and when it is desired to complement the capacity of the radiator12,the bypass25is open to guide the liquid-phase refrigerant to the water-refrigerant heat exchanger30to effectively cool the refrigerant by using the phase change of the refrigerant.
