Disclosed is a heat pump system for a vehicle, with improved structure and control logic to increase cooling efficiency of a battery and a defrosting effect of an outdoor heat exchanger. According to the present invention, a heat pump system for a vehicle comprises: a first coolant circulation line; a compressor installed in the first coolant circulation line to compress and discharge a coolant; a first outdoor heat exchange part to exchange the heat between the coolant discharged from the compressor and an outdoor air; a first throttling part to throttle the coolant passing through the outdoor heat exchange part; an evaporator installed inside an air conditioning case, to exchange the heat between an indoor air of the air conditioning case and the coolant which passed through the first throttle part; a first cooling water circulation line; a first water-coolant heat exchanger provided between the compressor and the outdoor heat exchange part, to exchange the heat between the coolant of the first coolant circulation line and the cooling water of the first cooling water circulation line; and an indoor heat exchanger installed inside the air conditioning case, to exchange the heat between the indoor air of the air conditioning case and the cooling water which passed through the first water-coolant heat exchanger.

    배터리의 냉각 효율 및 실외 열교환기의 제상 효과를 향상시키도록 구조 및 제어 로직이 개선된 차량용 히트펌프 시스템이 개시된다. 차량용 히트펌프 시스템은 제1 냉매 순환라인; 상기 제1 냉매 순환라인에 설치되어 냉매를 압축하여 배출하는 압축기; 상기 압축기에서 배출된 냉매를 외부 공기와 열교환시키는 제1 실외 열교환부; 상기 실외 열교환부를 통과한 냉매를 교축하는 제1 교축부; 공조케이스의 내부에 설치되어 공조케이스의 내부 공기와 제1 교축부를 통과한 냉매를 열교환시키는 증발기; 제1 냉각수 순환라인; 상기 압축기와 실외 열교환부의 사이에 구비되며, 제1 냉매 순환라인의 냉매와 제1 냉각수 순환라인의 냉각수를 열교환시키는 제1 수-냉매 열교환기; 및 공조케이스의 내부에 설치되어 공조케이스의 내부 공기와 제1 수-냉매 열교환기를 통과한 냉각수를 열교환시키는 실내 열교환기를 포함한다.
