The present invention relates to a vehicle air conditioner and, more specifically, to a vehicle air conditioner which supplies, to a variable heat exchanger, condensate water and air, that have been blown by means of a supply part and passed through an evaporator, so as to enable sub-cooling and overall performance of the variable heat exchanger to be improved during cooling, thereby further increasing cooling performance, and which may use air and condensate water as a heat-absorbing heat source during heating so as to further increase the heat absorption amount of the variable heat exchanger, so that heating performance may be further increased, and thus overall power consumption for air conditioning may be reduced and an increase in heat pump system performance may be promoted.
A vehicle air conditioner which is an air conditioner having an interior heat exchanger for air heating, a variable heat exchanger for condensing a refrigerant during air cooling and evaporating the refrigerant during air heating and an evaporator for the air cooling built therein, in a refrigerant loop configured of a compressor, the interior heat exchanger, a first expansion device, the variable heat exchanger, a second expansion device and the evaporator, the air conditioner comprising a supply part for supplying air passing through the evaporator and condensate water generated in the evaporator to the variable heat exchanger.
