Beschreibung
Zusammenfassung:	A refrigeration cycle device includes: a refrigeration cycle circuit including: a compressor and an indoor heat exchanger; an indoor air-sending device including a fan and a motor to supply air to the indoor heat exchanger; and a controller to control the frequency of the compressor and the rotation speed of the motor. The controller controls the rotation speed of the motor by controlling a frequency of an alternating current output from an inverter to the motor. The inverter is disposed at a position exposed to air heat-exchanged in the indoor heat exchanger. The controller controls the frequency of the compressor to a frequency at which a temperature of the inverter becomes lower than a first prescribed temperature in a state where the rotation speed of the motor is lower than a prescribed rotation speed.
