PURPOSE: A refrigerant discharge unit for an air conditioner of a vehicle is provided to improve cooling performance and efficiency by circulating liquid refrigerant smoothly because the amount of the liquid refrigerant, supplying to an expansion valve, is kept constantly. CONSTITUTION: A refrigerant discharge unit for an air conditioner of a vehicle is mounted on an air conditioner pipe(60), consisting of an inner pipe(61) and an outer pipe(63), and supplies cooled liquid refrigerant to an expansion valve. The inner pipe connects a compressor and an evaporator, and gas refrigerant of low temperatures and low pressures, supplying from the evaporator to the compressor, passes through the inner pipe. The outer pipe installs to be covered the exterior of the inner pipe and cools by exchanging heat between the liquid refrigerant of high temperatures and high pressures, supplying from a condenser through an refrigerant supply port forming in one side of the outer pipe, and the gas refrigerant. The refrigerant discharge unit comprises a refrigerant discharge pipe(110). One end of the refrigerant discharge pipe is inserted into a refrigerant discharge hole, forming in the other side of the outer pipe, corresponding to the expansion valve. The other side of the refrigerant discharge pipe connects to the expansion valve to reduce flow resistance of the liquid refrigerant, discharging to the refrigerant discharge hole, and supplies the liquid refrigerant to the expansion valve. |
