Abstract
A vehicle air-conditioning apparatus is provided which is capable of efficiently eliminating or suppressing fogging of a window while comfortably heating a vehicle interior. A controller changes and executes a heating mode to let a refrigerant discharged from a compressorradiate heat in a radiator, and a dehumidifying and heating mode to let the refrigerant discharged from the compressor radiate heat in the radiator and let the refrigerant absorb heat in a heat absorber. When the temperature of air blown out to the vehicle interior is not capable of reaching a target outlet temperature in the dehumidifying and heating mode, the controller actuates a window heaterheating a front windowand shifts to the heating mode.
