VEHICLE AIR CONDITIONING APPARATUS

A vehicle air conditioning apparatus includes: a refrigerant circuit including: a compressor; an outdoor heat exchanger; a heat releasing device; a first electronic expansion valve; a refrigerant-heat medium heat exchanger; and a second electronic expansion valve; a heat medium circuit; and a controller. The controller has heating modes including: an outdoor air heat absorption heating mode to absorb heat from the outdoor heat exchanger; and a waste heat recovery heating mode to absorb heat from the refrigerant-heat medium heat exchanger. When the outdoor air heat absorption heating mode is switched to the waste heat recovery heating mode, the controller controls the first electronic expansion valve to be closed, and controls a degree of superheat of the refrigerant to be increased on a downstream side of the refrigerant-heat medium heat exchanger.
