Abstract (en)
[origin: EP3862642A1] An air conditioner includes a refrigerant circuit (RC), an indoor unit (1) having a casing and an indoor fan (12), a humidified air supply device (3) that supplies humidified air into the casing, and a control device that performs cleaning operation of an indoor heat exchanger (11) by controlling the refrigerant circuit (RC) and the humidified air supply device (3) to supply humidified air from the humidified air supply device (3) into the casing and to cause the indoor heat exchanger (11) to function as an evaporator. The control device controls, during a first time period from when information related to start of the cleaning operation is received until a predetermined time elapses, the refrigerant circuit (RC) to restrict a flow rate of refrigerant to the indoor heat exchanger (11) more than during the cleaning operation or to set evaporation temperature (Te) of the indoor heat exchanger (11) higher than during the cleaning operation, and controls, after the first time period, the refrigerant circuit (RC) and the humidified air supply device (3) to perform the cleaning operation.
