The present invention provides a heat pump system for a vehicle, which comprises: a refrigerant circulation line where a compressor, a first heat exchanger, a second heat exchanger, and a chiller are arranged to allow a refrigerant to circulate; a freezing line allowing cooling water exchanging heat with air or the refrigerant to circulate to freeze a heating component; a cooling line, where a cabin cooler is disposed, cooling an indoor space of a vehicle by using the cooling water passing an evaporator; and a cooling connection line connecting the cooling line and the freezing line. The freezing line and the cooling line are connected through a first direction switch valve, and the freezing line and the cooling line are separated and connected according to an air conditioning mode.

    본 발명은 압축기, 제1 열교환기, 제2 열교환기 및 칠러가 배치되어 냉매가 순환하는 냉매 순환라인, 공기 또는 상기 냉매와 열교환되는 냉각수를 순환시켜 발열부품를 냉각하는 냉각라인, 캐빈 쿨러가 배치되며, 상기 증발기를 통과하는 냉각수를 이용하여 차량의 실내를 냉방하는 냉방라인 및 상기 냉방라인과 상기 냉각라인을 연결하는 냉방연결라인을 포함하며, 상기 냉각라인과 상기 냉방라인은 제1 방향전환밸브를 통해 연결되며, 공조모드에 따라, 상기 냉각라인과 냉방라인이 분리 및 연결되는 것을 특징으로 하는 차량용 히트펌프 시스템을 제공한다.
