PURPOSE: A cooling system of an air-conditioner for a vehicle is provided to reduce the discharge temperature of a compressor by the installation of a thermoelectric element module on a suction refrigerant pipe, thereby reducing the temperature of refrigerant flowing in the compressor. CONSTITUTION: A cooling system of an air-conditioner for a vehicle comprises a compressor(10), a condenser(20), an expansion valve(30), an evaporator(40), an internal heat exchanger(50), and a thermoelectric element module(100). The evaporator and the compressor are connected to a suction refrigerant pipe(P1). The condenser and the expansion valve are connected to a liquid refrigerant pipe(P2). The internal heat exchanger exchanges heat of refrigerants flowing in along the suction refrigerant pipe and the liquid refrigerant pipe, respectively. The thermoelectric element module is installed in the suction refrigerant pipe between the compressor and the internal heat exchanger. The thermoelectric element module is made of a cold block, a thermoelectric element, and a cooling fin.
