The present invention relates to a heat management system of a vehicle. The heat management system of a vehicle may control the flow of a refrigerant between heat exchangers in series or in parallel according to the state of an air conditioning mode, so that the flow rate of the refrigerant introduced into each heat exchanger may be independently controlled according to the state of the air conditioning mode. Therefore, the heat management system of a vehicle can introduce the refrigerant at an optimum flow rate for each heat quantity to each heat exchanger. To achieve this object, the vehicle heat management system includes: a compressor that sucks, compresses and discharges the refrigerant; a high-pressure side heat exchanger that heats air blown from a heat source to a space to be air-conditioned; an expansion valve to decompress the refrigerant flowing from the high-pressure side heat exchanger or outdoor heat exchanger; and at least one low-pressure side heat exchanger for evaporating the decompressed refrigerant, and the outdoor heat exchanger and the low-pressure side heat exchanger are connected in series or in parallel according to the air conditioning mode.

    본 발명은 차량의 열관리 시스템에 관한 것으로서, 공조 모드 상태에 따라, 열교환기 간의 냉매 흐름을 직렬 또는 병렬로 제어함으로써, 공조 모드 상태에 따라, 각 열교환기의 도입 냉매 유량을 각각 독립적으로 제어할 수 있고, 이를 통해. 각각의 열량에 맞는 최적 유량의 냉매를 각 열교환기에 도입할 수 있도록 하는 것을 목적으로 한다. 이러한 목적을 달성하기 위하여 본 발명은, 냉매를 흡입해 압축하여 토출하는 압축기와, 압축기에서 토출된 냉매의 열을 열원을 공조 대상 공간으로 송풍되는 공기를 가열하는 고압측 열교환기와; 냉매와 차실외 공기를 열교환하는 실외열교환기와; 고압측 열교환기 또는 실외열교환기에서 유출한 냉매를 감압시키는 팽창밸브를 구비하고; 감압된 냉매를 증발시키는 적어도 하나 이상의 저압측 열교환기를 구비하며; 실외열교환기와 저압측 열교환기가 공조 모드에 따라 직렬 또는 병렬로 연결되는 것을 특징으로 한다.
