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

In a refrigeration cycle in which a capacity-variable compressor a condenser, an expansion mechanism and an evaporator are connected in the order named, a device for controlling the capacity in the refrigeration cycle comprising a means for detecting the temperature of the compressor or the temperature of the gas discharged therefrom and a control device for limiting the maximum rotational speed of the compressor when the output from the means for detecting the temperature indicates a detected temperature lower than a predetermined level.
