PROBLEM TO BE SOLVED: To provide an air conditioner reduced in an amount of lubricant discharged from a compressor when activating heating operation under low outside air temperature.SOLUTION: An air conditioner includes: a cool air preventing mode where rotation frequency of an indoor fan is retained in a prescribed rotation frequency; and an oil discharge suppressing mode where the rotation frequency of a compressor is retained during a prescribe period of time at rotation frequency of the moment. The operation in the oil discharge suppressing mode is performed at a timing when the cool air preventing mode is released. Thus, the timing when the cool air preventing mode of the indoor fan 33 is released after activating the compressor 20, and a timing when the rotation frequency of the compressor 20 can be shifted, so that the amount of the lubricant discharged from the compressor 20 is reduced. |
