The present invention is provided with: a first refrigerant circuit (1) for air-conditioning the interior of a vehicle, the first refrigerant circuit (1) having a first refrigerant/internal gas heat exchanger (12) that exchanges heat between a first refrigerant and indoor air; a cooling water circuit (2) that cools the electrical component (23) with cooling water; a second refrigerant circuit (3) for adjusting the temperature of the battery, the second refrigerant circuit (3) having a second refrigerant/external air heat exchanger (39) for exchanging heat between the second refrigerant and the external air; a first refrigerant/cooling water heat exchanger (4) that exchanges heat between the first refrigerant and the cooling water; and a second refrigerant/cooling water heat exchanger (5) that exchanges heat between the second refrigerant and the cooling water. In the two-stage heat pump mode, the second refrigerant of the second refrigerant circuit (3) absorbs heat from the outside air in the second refrigerant/outside air heat exchanger (39) and releases heat to the cooling water of the cooling water circuit (2) in the second refrigerant/cooling water heat exchanger (5). A first refrigerant of a first refrigerant circuit (1) absorbs heat from cooling water of a cooling water circuit (2) in a first refrigerant/cooling water heat exchanger (4) and releases heat to indoor air in a first refrigerant/internal gas heat exchanger (12).

    本发明具备:车室内空调用的第一冷媒回路(1),其具有使第一冷媒与室内空气进行热交换的第一冷媒/内部气体热交换器(12);冷却水回路(2),其利用冷却水冷却电气部件(23);电池调温用的第二冷媒回路(3),其具有使第二冷媒与外部气体进行热交换的第二冷媒/外部气体热交换器(39);第一冷媒/冷却水热交换器(4),其使第一冷媒与冷却水进行热交换;以及第二冷媒/冷却水热交换器(5),其使第二冷媒与冷却水进行热交换。在两级热泵模式下,第二冷媒回路(3)的第二冷媒在第二冷媒/外部气体热交换器(39)中从外部气体吸热并且在第二冷媒/冷却水热交换器(5)中向冷却水回路(2)的冷却水放热,第一冷媒回路(1)的第一冷媒在第一冷媒/冷却水热交换器(4)中从冷却水回路(2)的冷却水吸热并且在第一冷媒/内部气体热交换器(12)中向室内空气放热。
