냉방용 감압 기능과 제습용 감압 기능을 함께 수행할 수 있는 개선된 구조의 복합 밸브 유닛을 제공함과 아울러 냉매유량 분배를 능동적으로 제어하여 제습 성능을 향상시킬 수 있는 차량용 히트펌프 시스템이 개시된다. 복합 밸브 유닛은 차량용 히트펌프 시스템의 냉매를 교축하는 수단으로서, 실내의 냉방을 수행하는 냉방용 감압부와 실내의 제습을 수행하는 제습용 감압부의 유입구를 각각 형성한다.

    Provided is a combination valve unit having an improved structure and capable of performing both a pressure relief function for cooling and a pressure relief function for dehumidification. In addition, disclosed is a vehicle heat pump system capable of improving dehumidification performance by actively controlling the refrigerant flow distribution. The combination valve unit serves as a refrigerant throttling means in a vehicle heat pump system, and forms the inlet for a cooling pressure relief unit for performing indoor cooling and the inlet for a dehumidification pressure relief unit for performing indoor dehumidification, respectively.
