Abstract
A vehicle air-conditioning device may achieve comfortable heating of a vehicle interior by starting a compressor, an indoor blower and heat generating means at appropriate timing. The vehicle air-conditioning device includes a compressor which compresses a refrigerant, a radiator disposed in an air flow passage to let the refrigerant radiate heat, a heat absorber which lets the refrigerant absorb heat, and an indoor blower which blows the air through the air flow passage. The vehicle interior is heated by heat radiated from the radiator. The vehicle air-conditioning device includes a heating medium-air heat exchanger of a heating medium circulating circuit disposed in the air flow passage to heat air supplied to the vehicle interior. On a basis of an outdoor air temperature, the timing to start the compressor, the indoor blower and the heating medium circulating circuit is controlled.
