PROBLEM TO BE SOLVED: To perform comfortable room temperature control by preventing cold air feeling caused by lowering supply air temperature from an indoor unit in a cooling operation. SOLUTION: The lowering of supply air temperature from the indoor unit in the cooling operation is prevented by controlling a rotational frequency of an air blower for an outdoor unit on the basis of an indoor supply air temperature, an outdoor outside air temperature, and a compressor operational frequency, controlling an opening of an indoor expansion valve on the basis of the indoor supply air temperature, and ON/OFF control of a solenoid valve for a bypass circuit on the basis of a discharge temperature of the compressor to provide comfortable indoor air-conditioning.
