팽창밸브로 기상 냉매의 유입을 방지하고 액상의 냉매가 보다 잘 유입되게 함으로써 이상 소음의 발생을 개선한 차량용 공조장치의 냉방시스템이 개시된다. 차량용 공조장치의 냉방시스템은 압축기, 응축기, 팽창밸브, 증발기를 냉매 배관으로 연결하여 구성되고, 상기 증발기와 압축기를 연결하는 석션 배관 및 상기 응축기와 팽창밸브를 연결하는 리퀴드 배관을 포함하며, 상기 리퀴드 배관은 팽창밸브 측으로 기상 냉매의 유입을 억제하고 액상 냉매의 유입을 유도하는 기상 냉매 유입 억제부를 구비하며, 더욱 상세하게는, 상기 리퀴드 배관은 팽창밸브의 리퀴드 포트보다 높이 방향으로 더 높은 위치에서 굴곡되는 변곡점부를 구비한다.

    Disclosed is a cooling system of an air conditioner for a vehicle, which prevents the generation of noise by preventing a gaseous refrigerant from flowing into an expansion valve and enabling a liquefied refrigerant to flow inside. The cooling system of the air conditioner for a vehicle comprises a compressor, a condenser, an expansion valve, and an evaporator, which are connected by a refrigerant pipe. The cooling system of the air conditioner for a vehicle includes: a suction pipe connecting the evaporator and the compressor; and a liquid pipe connecting the condenser and the expansion valve. The liquid pipe includes a refrigerant inflow suppressing unit suppressing the inflow of the liquefied refrigerant toward the expansion valve and inducing the inflow of the liquefied refrigerant. Specifically, the liquefied pipe includes an inflection point bent at a position higher in the height direction than a liquid port of the expansion valve.
