For example, the first wire harness 71 may be arranged along the inner corner 323 of the water storage tank 32, and the second wire harness 72 may be arranged along the front surface 322 of the water storage tank 32. In this case, the protrusion 35 of the heat exchanger 3 is used to position the first wire harness 71. Furthermore, the first wire harness 71 may be arranged along the water storage tank 32 and the second wire harness 72 may not be arranged along the water storage tank 32 , or the second wire harness 72 may be arranged along the water storage tank 32 and the first wire harness 71 may not be arranged along the water storage tank 32 .

The first wire harness 71 and the second wire harness 72 may be arranged along the inner corner 323 of the water storage tank 32.
