Abstract

This air conditioner is provided with: a heat exchanger (indoor heat exchanger (15)); a fan cleaning part (24) that cleans a blower fan (indoor fan (16)); and a control unit (30) that causes the fan cleaning part to selectively come into contact with both the heat exchanger and the blower fan. The control unit causes the heat exchanger to generate dew condensation water in a refrigeration cycle, before the fan cleaning part comes into contact with the heat exchanger or while the fan cleaning part is in contact with the heat exchanger.
