The present invention relates to a heat pump system for a vehicle, and more specifically, to the heat pump system for a vehicle which allows a refrigerant to bypass an outdoor heat exchanger and controls to turn off a fan installed on an outdoor heat exchanger side when outdoor temperature of a vehicle is equal to or less than set temperature during a heat pump mode. Accordingly, heating performance can be maintained by continuously operating the heat pump mode below zero temperature, and there is no need to additionally operate an electric heating type heater so that power consumption can be reduced. In addition, when the vehicle accesses the idle state below the zero temperature, an excessive fan noise can be prevented.

    본 발명은 차량용 히트 펌프 시스템에 관한 것으로써, 더욱 상세하게는 히트펌프 모드시, 차량 외기온도가 설정온도 이하이고 차량이 아이들(idle)로 진입하면 냉매가 실외열교환기를 바이패스하도록 함과 아울러 실외열교환기측에 설치된 팬을 오프 제어함으로써, 영하 조건에서도 히트펌프 모드를 연속적으로 작동시켜 난방성능을 유지함과 아울러 전기가열식히터를 추가로 작동시킬 필요가 없어 소비전력도 줄일 수 있고, 영하 조건에서 차량의 아이들 진입시 과도한 팬 소음을 방지할 수 있는 차량용 히트 펌프 시스템에 관한 것이다.
