본 발명은 차량용 냉난방시스템의 난방모드 운전 시, 냉매를 압축하는 압축기에 선택적으로 중간압의 냉매가스가 유입되도록 하여, 압축기로 인입되는 냉매 유량을 증가시켜 난방성능이 높아지고, 냉매가 냉각수의 폐열을 회수하는 칠러 전단(입력측)에 냉매 간의 열교환이 이루어지는 내부열교환기를 적용하거나, 플래시탱크를 적용하여 냉매 유량 감소로 인한 난방성능 저하를 방지하며, 압축기로 유입되는 냉매 유량을 조절함으로써 난방성능을 제어할 수 있어, 압축기의 소비전력을 최소화할 수 있는 차량용 냉난방시스템을 제공한다.

    The present invention relates to an air conditioning system for a vehicle. In a heating mode, refrigerant gas of intermediate pressure selectively flows into a compressor, which compresses refrigerant, in order to increase a flow rate of refrigerant entering into the compressor, thereby enhancing heating performance. An internal heat exchanger for exchanging heat between the refrigerants is applied to the front end (input side) of a chiller, in which the refrigerant collects waste heat of cooling water, or a flash tank is applied, in order to prevent deterioration in heating performance caused by decrease of the refrigerant flow rate, to control heating performance by regulating the flow rate of refrigerant flowing into the compressor, and to minimize power consumption of the compressor.
