PROBLEM TO BE SOLVED: To shorten a time until a temperature difference between a refrigerant discharge temperature of a compressor and a temperature of an outdoor heat exchanger or an indoor heat exchanger reaches a temperature difference at which a refrigeration cycle is stabilized.SOLUTION: An air conditioner 1 includes: an outdoor heat exchanger 14; an indoor heat exchanger 32; an expansion valve 15; a compressor 12; and a switch valve 13 for switching a refrigerant circulation by the compressor to a cooling circulation in which a refrigerant discharged from the compressor 12 enters the outdoor heat exchanger first, and a heating circulation in which the refrigerant discharged from the compressor 12 enters the indoor heat exchanger 32 first. A control portion 40 performs such control that an operation of a fan combined with the heat exchanger functioning as a condenser during the operation, out of an outdoor fan 16 or an indoor fan 33, is stopped or is started at a low speed rotation, and then a rotating speed of the fan is increased after the refrigerant discharge temperature of the compressor 12 rises to a prescribed value. |
