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. L'invention concerne une unité de soupape combinée ayant une structure améliorée et capable de réaliser à la fois une fonction de détente de pression pour le refroidissement et une fonction de détente de pression pour la déshumidification. De plus, l'invention concerne un système de pompe à chaleur de véhicule capable d'améliorer les performances de déshumidification par commande active de la distribution de flux de fluide frigorigène. L'unité de soupape combinée sert de moyen d'étranglement de fluide frigorigène dans un système de pompe à chaleur de véhicule et forme l'entrée pour une unité de détente de pression de refroidissement afin de réaliser un refroidissement intérieur et l'entrée pour une unité de détente de pression de déshumidification afin de réaliser une déshumidification intérieure, respectivement. 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.
