Abstract

See full text

There is provided a vehicle air-conditioning device capable of smoothly achieving pre-air-conditioning for preliminarily heating a vehicle interior without forming frost on an outdoor heat exchanger or while preventing frost formation thereon as much as possible. When the temperature of a battery 55 or a motor 65 for running is higher than or equal to a predetermined specified value upon executing the pre-air-conditioning for preliminarily heating the vehicle interior before boarding, a controller 32 operates a compressor 2 to let a refrigerant discharged from the compressor radiate heat in a radiator 4, decompress the refrigerant from which the heat is radiated, and then let the refrigerant absorb heat in a waste heat recovering heat exchanger 64 without using an outdoor heat exchanger 7.
