PROBLEM TO BE SOLVED: To provide an air conditioner which can restart heating operation in a state that a heating capacity is sufficiently exercised when the heating operation, which is stopped due to an extreme decrease in an outside air temperature, is restarted.SOLUTION: An air conditioner 1 includes an outdoor unit 10 and an indoor unit 30. The outdoor unit 10 includes an outdoor heat exchanger 16, a compressor 11, an outdoor blower 15, a temperature detector 23 for detecting a temperature of the outdoor heat exchanger 16, and a temperature detector 27 for detecting an outside air temperature. The indoor unit 30 includes an indoor heat exchanger 33 and an indoor blower 32. The air conditioner 1 has a heating operation mode which becomes a standby state by stopping the heating operation when the outside air temperature reaches a temperature lower than a first predetermined temperature which is previously set during the heating operation, and then restarts the heating operation after executing defrosting operation when the outside air temperature reaches a temperature higher than a second predetermined temperature, which is previously set and is higher than the first predetermined temperature. |
