Abstract
An air conditioner for a vehicle includes a refrigerant cycle having an evaporator which is disposed in a blowing duct and cools air by refrigerant evaporation in the blowing duct; a compressor setting the evaporated refrigerant at a high temperature and high pressure; a refrigerant-to-water heat exchanger heating cooling water by heat transfer from the refrigerant discharged from the compressor; and an expansion device decompressing the refrigerant discharged from the refrigerant-to-water heat exchanger. The air conditioner also includes a cooling water cycle having a heater core which is disposed on the downstream side of the evaporator; a radiator cooling the cooling water; a pump circulating the cooling water cooled by the radiator; a power engine cooled by the cooling water fed by the pump; and the refrigerant-to-water heat exchanger. The refrigerant cycle performs cooling for dehumidification by performing the operation of heating.
