PURPOSE: A cooling system of an air conditioner for a vehicle is provided to improve the durability of a refrigerant pipe at the outlet side of a compressor and a compressor by increasing the quantity of oil contained in a discharge refrigerant and decreasing the temperature of a refrigerant discharged from a compressor. ;CONSTITUTION: A cooling system of an air conditioner for a vehicle comprises: a compressor(10) inhaling and compressing a refrigerant; a condenser(20) condensing the refrigerant compressed in the compressor; an expansion valve(30) throttling the refrigerant condensed in the condenser; an evaporator(40) evaporating the refrigerant influent from the expansion valve; an internal heat exchanger(50) transferring heat between refrigerants flowing along a low temperature refrigerant pipe(P1) connecting the evaporator and the compressor and a high temperature refrigerant pipe(P2) connecting the condenser and the expansion valve; and a discharge refrigerant temperature reduction device reducing the temperature of a refrigerant discharged from the compressor by reducing the refrigerant discharge capacity of the compressor at over appointed vehicle speed.;COPYRIGHT KIPO 2011
