Abstract
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 batteryor a motorfor 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 controlleroperates a compressorto let a refrigerant discharged from the compressor radiate heat in a radiator, decompress the refrigerant from which the heat is radiated, and then let the refrigerant absorb heat in a waste heat recovering heat exchangerwithout using an outdoor heat exchanger
