The present invention relates to a heat pump apparatus for an electric vehicle having a vehicle cabin heating circuit and a battery heating circuit. An objective of the present invention is to satisfy the demand for a vehicle cabin and a battery at low additional device costs. The vehicle cabin heating circuit of the heat pump apparatus includes a heating heat exchanger (19), a 4/2-way valve (35), a coolant pump (17), and a heating device (23) for directly heating vehicle cabin air in the flow direction of a heat carrier. A warm side of a coolant-coolant heat exchanger (37) is connected to the vehicle cabin heating circuit through the 4/2-way valve (35) for indirect heating of the battery heating circuit. The battery heating circuit includes a battery heat exchanger (25), a coolant pump (22), and a coolant-coolant heat exchanger (37). A cold side of the coolant-coolant heat exchanger (37) is integrated in the battery heating circuit.

    본 발명은 차량 객실 가열 회로 및 배터리 가열 회로를 구비한 전기 차량용 열 펌프 장치에 관한 것이며, 상기 열 펌프 장치는, 상기 차량 객실 가열 회로가 열 운반체의 유동 방향으로, 가열 열교환기(19), 4/2-방향 밸브(35), 냉각제 펌프(17) 및 차량 객실 공기를 직접 가열하기 위한 가열 장치(23)를 포함하고, 냉각제-냉각제 열교환기(37)의 따뜻한 측면은 상기 배터리 가열 회로의 간접 가열을 위해 상기 4/2-방향 밸브(35)를 통해 상기 차량 객실 가열 회로에 연결되며, 상기 배터리 가열 회로는 배터리 열교환기(25), 냉각제 펌프(22) 및 상기 냉각제-냉각제 열교환기(37)를 포함하고, 상기 냉각제-냉각제 열교환기(37)의 차가운 측면은 상기 배터리 가열 회로 내에 통합되는 것을 특징으로 한다.
