車両用空気調和装置。 A vehicle that has a hot water heater type heating system that uses engine cooling water as a heat source, and a heat pump type air conditioning system that is equipped with a refrigerant circulation circuit that includes a compressor, an outdoor heat exchanger, a pressure reduction means, and an indoor heat exchanger. In the air conditioner for air conditioning, the heating heat exchanger uses engine cooling water as a heat source supplied from a circulation path branched from the circulation path for the engine cooling water to the hot water heater via an engine cooling water path switching means. A path that is installed in a refrigerant circulation circuit of a heat pump air conditioning system and circulates the refrigerant discharged from the compressor through the outdoor heat exchanger, the pressure reduction means, and the indoor heat exchanger in this order, and the indoor heat exchanger, the pressure reduction means, and the heating device. There is also a means for detecting the engine cooling water temperature, and a means for detecting the temperature of the engine cooling water based on a detection signal from the engine cooling water temperature detecting means. control means for switching the switching means for the engine cooling water path so as to supply the engine cooling water to the hot water heater when the temperature is lower than a predetermined temperature; A vehicle air conditioner characterized by being provided with.
