調和機の除霜制御装置。 It is equipped with a compressor 1, an indoor heat exchanger 3, an outdoor heat exchanger 4 equipped with an outdoor fan 11 consisting of an axial flow fan, pressure reducing mechanisms 6 and 7, and a four-way switching valve 2 that converts the refrigerant circuit according to air conditioning/heating operation. In the air conditioner, an outdoor fan rotation speed detection means 12 detects the rotation speed of the outdoor fan 11, the number of outdoor fan circuits at the time of starting heating immediately after startup or after the end of defrosting operation, and the outdoor fan rotation when frosting progresses. a defrosting start condition comparing means 30 which compares the difference between the two and a set value; and a defrosting start which determines the defrosting start time upon receiving a signal from the defrosting start condition comparing means 30. A defrosting control device for an air conditioner, comprising a determining means 32 and a defrosting control means 33 for receiving a signal from the defrosting start determining means 32 and outputting a defrosting control signal to the outside.
