SOLUTION: This air conditioner comprises an air conditioning means comprising an indoor unit and an outdoor unit for conditioning the indoor air, and a controller comprising an operation control portion and a fluctuation control portion. An indoor heat exchanger of the indoor unit, a compressor of the outdoor unit, a four-way switch valve, an outdoor heat exchanger and an expansion valve are successively connected to constitute a refrigerant circuit of a vapor compression type refrigerating cycle. The operation control portion controls an operation of the air conditioning means, conditions the indoor air to a prescribed temperature by the indoor heat exchanger of the indoor unit, and supplies the air indoors. An operation capacity of the compressor is controlled to change the indoor temperature within a temperature fluctuation range of 26.5-28°C every half-hour cycle. COPYRIGHT: (C)2008,JPO&INPIT |
