Abstract: At the time of dehumidifying operation, a motor-operated expansion valve is controlled so that evaporation of a refrigerant will be completed in an auxiliary indoor heat exchanger which constitutes an indoor heat exchanger together with a main indoor heat exchanger. A louver is operated to form an air passage through which air discharged from the outlet port of an indoor unit flows to the inlet port. Owing to the formation of such an air passage from the outlet to the inlet port of the indoor unit, dehumidification is performed with outlet air kept from reaching the living space in the room.

Abstract: An air conditioning machine has a unit main body having an inlet port and an outlet port. The unit main body includes a cross flow fan, having a circular cross section, for introducing indoor air into the unit main body through the inlet port and blowing the air into the room. A heat exchanger is arranged on an indoor air introducing side of the cross flow fan and bent at a portion along a longitudinal direction of the heat exchanger at an acute angle. The heat exchanger has a front side heat exchanger located on a front side of the air conditioning machine and curved along the circular cross section of the cross flow fan and a rear side heat exchanger located on a rear side thereof.

Openable/closable covers are provided to the second inlet. The covers are closed when a silent operation mode is set by an operation unit. When the covers are closed, the second inlet is closed, and the sound caused by a hissing indoor fan in the indoor unit and the sound of the refrigerant flowing in the indoor heat exchanger of the indoor unit will not leak to the outside of the indoor unit.

Abstract: A refrigeration cycle has a compressor, an outdoor rotary-type heat exchanger, a motor-operated expansion valve, and an indoor rotary-type heat exchanger which are sequentially connected to each other to circulate a refrigerant. A tank is set in a connected state or a non-connected state with respect to a refrigerant discharge side of the compressor. A detector detects at least a pressure at one side of each of the exchangers. A first controller sets the tank in a non-connected state when a normal operation of an air conditioner is to be started, and controls the capacity of the compressor, the rotational speed of the exchangers, and the opening degree of the valve in accordance with an air-conditioning load, thereby performing the normal operation of the air conditioner.

Abstract: A detected temperature T.sub.m of the atmosphere of a remote controller is read in at a predetermined detection time interval. When a difference between a present or new detected temperature T.sub.m and a last or old detected temperature T.sub.m(old) is above a predetermined value, a first correction value corresponding to the temperature difference (T.sub.s -T.sub.m) is added to a set temperature T.sub.s set in advance to thereby determine a set temperature T.sub.sc. On the other hand, when a difference between a present or new detected temperature T.sub.m and a last or old detected temperature T.sub.m(old) is less than the predetermined value, a second correction value corresponding to the temperature difference (T.sub.s -T.sub.m) is added to the last or old set temperature T.sub.sc(old) to thereby determine a corrected set temperature T.sub.sc, thus to operate a compressor motor in dependency upon a difference between the corrected set temperature T.sub.
