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

Vehicle air-conditioning device

A vehicle air-conditioning device includes a compressor, a radiator, an outdoor heat exchanger, a first heat medium circulating deviceto let a first heat medium circulate in a heat medium heating heater, and a second heat medium circulating deviceto let a second heat medium circulate in a battery. The first heat medium circulating device has a first heat medium heat exchanging unitA which exchanges heat between a refrigerant and the first heat medium. The second heat medium circulating device has a second heat medium heat exchanging unitB which exchanges heat between the first heat medium and the second heat medium.
