PROBLEM TO BE SOLVED: To solve a problem caused when a compressor is stopped while driving of a blower fan is continued, wherein a rotation speed of a fan motor increases suddenly and temporarily to produce noise.SOLUTION: A refrigeration cycle apparatus includes: a blower fan 8 for blowing wind to an evaporator 5; a converter circuit 19 for converting an alternating current of an AC power source 16 to a direct current; a compressor motor 12 connected to a secondary side of the converter circuit 19 via an inverter circuit 20, for driving a compressor 1; a fan motor 13 connected to the secondary side of the converter circuit 19, for driving the blower fan 8; a control means 23 for controlling the inverter circuit 20 so that the compressor motor 12 is driven at a desired rotation speed and changing a speed command value so that the fan motor 13 reaches a desired rotation speed; and a speed command correction means 24 for correcting the speed command value for the fan motor 13 in substantially synchronization with timing of a drive stop of the compressor motor 12 when driving of the compressor motor 12 is stopped while continuing driving of the fan motor 13. |
