An air conditioner having an indoor unit and an outdoor unit which are connected by a refrigerant pipe and electric cables. The indoor unit has a housing, in which a heat exchanger, a fan device and a compressor are arranged. A partition divides the interior of the housing into a fan chamber and a compressor chamber. The fan chamber contains the fan and opens at the front of the housing. The compressor chamber contains the compressor and opens at the back of the housing. Not incorporating the compressor, the outdoor unit is smaller and lighter than otherwise. The indoor unit is secured to the wall of a room, with the back of the housing facing the wall. Hence, the noise the compressor makes while operating does not annoy the persons in the room is much.

Indoor unit for an air-conditioning apparatus

An air conditioner having an indoor unit and an outdoor unit. The indoor unit has a compressor, an indoor heat exchanger, and a indoor fan. The outdoor unit has an outdoor heat exchanger, a capillary tube, and an outdoor fan. In use, the indoor unit is connected to a commercial AC power supply. A driving circuit is provided in the indoor unit, for applying a voltage via a power-supply line to the outdoor unit to drive the outdoor fan. This voltage is lower than the voltage of the commercial AC power supply. Thus, the power-supply line can be connected to the indoor and outdoor units, with ease and in safety.
