PROBLEM TO BE SOLVED: To provide a novel application of a heat exchanger among a refrigerant, air, and cooling water.SOLUTION: An air conditioner 1 includes a refrigerant circuit 10 and a cooling water circuit 40. The air conditioner 1 includes a heat exchanger 70 that functions as an indoor heat exchanger 20. The heat exchanger 70 includes: a refrigerant heat exchanger 16 that exchanges heat between a refrigerant RF and air UR; and a radiator 43 that exchanges heat between cooling water WT and the air UR. The refrigerant heat exchanger 16 and the radiator 43 are thermally connected. The heat exchanger 70 cools the air UR by an operation of the refrigerant circuit 10. The heat exchanger 70 cools or heats the air UR by an operation of the cooling water circuit 40. Further, when the refrigerant circuit 10 and the cooling water circuit 40 are operated, the heat exchanger 70 cools the cooling water WT with the refrigerant RF. |
