본 발명은 차량용 공조장치에 관한 것으로서, 압축기의 제어구조를 개선함으로써, 차실내의 냉방성능이 저하되지 않는 한도내에서 압축기의 "과도한 회전속도 증가"를 방지할 수 있고, 이를 통해, 압축기의 "과도한 회전속도 증가"로 인한 압축기와 각종 냉매배관과 씰링부품의 열화, 손상, 파손을 방지할 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 압축기와 실외열교환기와 팽창밸브와 실내열교환기를 구비하는 냉매순환라인을 포함하는 차량용 공조장치에 있어서, 압축기의 출구측 냉매토출압력과 냉매토출온도에 따라, 압축기의 회전속도를 가변 제어하는 제어부를 더 구비한다.

    The present invention relates to an air conditioner for a vehicle, which can improve a control structure of a compressor to prevent an excessive increase in a rotation speed of the compressor within a limit in which cooling performance of the interior of the vehicle is prevented from being reduced. Accordingly, deterioration, damage, and breakage of the compressor and various types of refrigerant pipes and sealing components due to the excessive increase in the rotation speed of the compressor can be prevented. To this end, the air conditioner for a vehicle comprises a refrigerant circulation line provided with the compressor, an outdoor heat exchanger, an expansion valve, and an indoor heat exchanger, and further comprises a control unit configured to variably control the rotation speed of the compressor in accordance with refrigerant discharge pressure and refrigerant discharge temperature of an outlet of the compressor.
