Abrégé
Provided is an air conditioner that cleans an indoor heat exchanger and prevents condensation from dripping. A control unit (30) for an air conditioner (100) performs a freezing process for causing an indoor heat exchanger (15) to function as an evaporator and to freeze. If the detected value of an indoor temperature sensor is equal to or greater than a first prescribed value, the control unit (30) either does not perform the freezing process, or shortens the freezing process duration time or decreases the rotational speed of a compressor motor (11a) during the freezing process even when performing the freezing process. The first prescribed value is lower than the upper limit for the set temperature that can be changed by a remote control during cooling operation or heating operation.Classes IPC ?
