PURPOSE: An air conditioner system for a vehicle is provided to improve cooling performance by increasing the area and temperature of a sub cooling portion with increasing heat exchange efficiency, and to prevent the increase of the internal temperature by lowering the super heat of a refrigerant to below a set temperature. CONSTITUTION: An air conditioner system for a vehicle comprises an expansion valve(101), an evaporator(103), an electric compressor(105), a water-cooled condenser(110), and a heat exchanger(120). The water-cooled condenser condenses a refrigerant entering from the electric compressor by heat-exchanging with cooling water fed from a radiator through a cooling line. The heat exchanger is installed on a refrigerant line between the water-cooled condenser and the evaporator, and exchanges heat between the liquid refrigerant at the medium temperature and high pressure passing through the water-cooled condenser, and the refrigerant at low temperature and low pressure passing through the evaporator. |
