The present invention relates to an air conditioner for a vehicle, which aims to, when there is a difference in the internal pressure between a heat exchanger and a compressor due to differences in the atmospheric temperature between day and night, prevent a one-sided oil flow from the compressor side toward the heat exchanger side, to prevent the oil accumulation on the heat exchanger side due to the one-sided oil flow from the compressor side to the heat exchanger side, and to prevent the lack of oil in the compressor side. To this end, in the air conditioner for the vehicle which comprises: a compressor; a plurality of heat exchangers which make a refrigerant discharged from the compressor exchange heat with the surrounding air; and refrigerant pipes connecting the compressor to the heat exchangers, the air conditioner for the vehicle additionally comprises an oil flow prevention unit which allows the refrigerant to flow between the compressor and the heat exchangers but does not allow the oil to flow from the compressor side to the heat exchanger side.

    본 발명은 차량용 공조장치에 관한 것으로서, 밤낮의 기온차로 인한 열교환기와 압축기 간의 내부 압력차 발생 시에, 압축기측에서 열교환기측으로의 일방적인 오일 유동 현상을 방지하여, 압축기측에서 열교환기측으로의 일방적인 오일 유동으로 인한 열교환기측의 오일 누적과, 그로 인한 압축기측의 오일 부족현상을 방지할 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 압축기와, 압축기에서 토출되는 냉매와 주변공기를 열교환시키는 복수의 열교환기 및, 압축기와 열교환기를 연결하는 냉매배관들을 포함하는 차량용 공조장치에 있어서, 압축기와 열교환기 상호 간의 냉매 유동은 허용하고, 압축기측에서 열교환기측으로의 오일 유동은 제한하는 오일유동 방지구를 더 구비한다.
