Abstract
A vehicle air conditioning device executes an air conditioning operation for heating inside of a cabin by causing a refrigerant discharged from a compressorto dissipate heat in a radiator, decompressing the refrigerant, and then causing the refrigerant to absorb heat in an outdoor heat exchanger, and includes an equipment temperature adjusting devicecapable of adjusting, using the refrigerant, the temperature of a batteryand the temperature of a traveling motor, which is a temperature-adjusted object other than the battery, the batteryand the traveling motorbeing mounted on a vehicle. An air conditioning controller has a heating/waste heat recovery mode for cooling the traveling motorwithout cooling the battery with the refrigerant by controlling the equipment temperature adjusting devicein the air conditioning operation for heating the inside of the cabin.
