Title: AIR CONDITIONER
Abstract:
This air conditioner (for example, an indoor unit) (2) has: a heat exchanger (16) which performs heat exchange between air and a refrigerant; a plurality of fins (20) provided in the heat exchanger; and a control unit (CL) which performs an operation for lowering the temperature of the heat exchanger and controls a freezing operation for attaching frost or ice onto surfaces of the fins. In the heat exchanger, installation angles in a front upper part, a front lower part, and a rear part are different. The installation angles in the front upper part, the front lower part, and the rear part with respect to the normal line of an installation wall surface are within 50°±10°, 85°±10°, and 50°±10°, respectively. The control unit also performs an operation for raising the temperature of the heat exchanger and controls a thawing action for thawing frost or ice.
