The present invention provides a heat pump system for a vehicle comprising: a refrigerant circulation line in which a compressor, a water-cooled condenser, an expansion valve and an evaporator are arranged, and a refrigerant circulates to cool the room; and a cooling water circulation line having a heating line for heating the room by circulating cooling water exchanged with the refrigerant through the water-cooled condenser, and a cooling line for cooling a battery and electronic components by circulating air or cooling water exchanging heat with the refrigerant. A reservoir tank through which the cooling water of the heating line and the cooling water of the cooling line passes is disposed in the cooling water circulation line. There is an effect that can increase the heat exchange efficiency.

    본 발명은 압축기, 수냉식 응축기, 팽창밸브 및 증발기가 배치되며, 냉매를 순환시켜 실내를 냉방하는 냉매순환라인, 상기 수냉식 응축기를 통해 상기 냉매와 열교환되는 냉각수를 순환시켜 실내를 난방하는 난방라인과 공기 또는 상기 냉매와 열교환되는 냉각수를 순환시켜 배터리 및 전장부품을 냉각시키는 냉각라인을 구비하는 냉각수 순환라인을 포함하며, 상기 냉각수 순환라인에는 상기 난방라인의 냉각수와 상기 냉각라인의 냉각수가 통과하는 리저버 탱크가 배치되는 것을 특징으로 하는 차량용 히트펌프 시스템을 제공한다.
