Disclosed is an integrated thermal management circuit for a vehicle, which comprises: a refrigerant line which allows a refrigerant to flow from a compressor, an indoor condenser of an indoor air conditioning device, and an outdoor heat exchanger in order, wherein the refrigerant discharged from the outdoor heat exchanger is branched to be introduced into a chiller line and an evaporation line, with the chiller line being provided with a full-length chiller and a battery chiller being connected in parallel, before the refrigerant passing through the chiller line and the evaporation line is joined to be introduced into the compressor; a battery cooling line which allows a coolant to circulate between a battery and a battery radiator, or between the battery and a battery chiller; a full-length cooling line which allows the coolant to circulate between an electrical operating unit and a full-length radiator, or between the electrical operating unit and the full-length chiller; and a chiller control valve which is disposed upstream from the full-length chiller and the battery chiller on the refrigerant line, and allows the refrigerant, discharged from the outdoor heat exchanger, to be introduced into the full-length chiller or the battery chiller. Therefore, heating by means of a heat pump may be independently performed.
압축기, 실내공조장치의 실내컨덴서, 실외열교환기 순으로 냉매가 흐르도록 하며, 실외열교환기에서 토출된 냉매는 분기되어 칠러라인과 증발라인으로 유입되고, 칠러라인에는 전장칠러 및 배터리칠러가 병렬연결되며, 칠러라인 및 증발라인을 통과한 냉매는 합류되어 압축기로 유입되는 냉매라인; 배터리와 배터리라디에이터의 사이 또는 배터리와 배터리칠러 사이를 냉각수가 순환하도록 하는 배터리냉각라인; 전자구동부와 전장라디에이터의 사이 또는 전자구동부와 전장칠러 사이를 냉각수가 순환하도록 하는 전장냉각라인; 및 냉매라인 상에서 전장칠러 및 배터리칠러의 상류지점에 마련되며, 실외열교환기에서 토출된 냉매가 전장칠러 또는 배터리칠러로 유입되도록 하는 칠러컨트롤밸브;를 포함하는 차량의 통합 열관리 회로가 소개된다.
