PROBLEM TO BE SOLVED: To solve the following problem of an inactivation method for microbes growing in an indoor machine of a conventional air conditioner: because it is necessary to humidify the whole inside of a casing and to raise a temperature of it to inactivate the microprobe inside the indoor machine casing, a humidification means for evaporation or the like of moisture inside the indoor machine casing is required to increase cost of the air conditioner. SOLUTION: When an instruction for inactivation operation is issued when performing a cooling cycle operation, it is confirmed whether or not the surface of an indoor heat exchanger is covered with dew condensation water by a dew condensation sensor. When covered with the dew condensation water, a fan is stopped, and reverse cooling cycle operation is performed to raise a temperature of the indoor heat exchanger. A surface temperature of the indoor heat exchanger is measured by a temperature sensor, and the indoor heat exchanger is held at a protein denaturation temperature of the microprobe or above for a prescribed time when reaching the temperature.
