Definitions

  • an air conditioner which includes an outdoor heat exchanger, an indoor heat exchanger, a four-way valve, and a compressor and which performs defrosting by melting frost deposited on the outdoor heat exchanger with a refrigerant heated by the compressor, the air conditioner comprising:
  • the air conditioner further comprises outdoor temperature detection means for detecting outdoor temperature, wherein the defrosting means controls a rotation speed of the indoor fan based on an outdoor temperature detected by the outdoor temperature detection means.
  • the refrigerant having entered the refrigerant pipe 32 joins with the refrigerant flowing in the refrigerant pipe 24, passes through the accumulator 26, and enters the intake port of the compressor 6.
  • the heat quantity required for defrosting becomes higher under a lower outdoor temperature, than in cases of higher outdoor temperatures. Accordingly, under a lower outdoor temperature, it is preferable to exert control so that the rotation speed of the indoor fan becomes lower than those of higher-temperature cases, thereby allowing larger amounts of heat to be supplied to the outdoor heat exchanger.
