PROBLEM TO BE SOLVED: To provide a refrigeration cycle device capable of suppressing refrigerant passage noise in the refrigeration cycle device.;SOLUTION: A refrigeration cycle device 1 includes: a compressor 11 for compressing and discharging a refrigerant; a condenser 12 for condensing the refrigerant discharged from the compressor 11; a decompression section 13 for decompressing a high pressure refrigerant flowing out from the condenser 12; an evaporator 14 for evaporating a low pressure refrigerant decompressed by the decompression section 13 and causing the refrigerant to flow out to a suction side of the compressor 11; an air bubble determination section 19a for determining whether there is a possibility that air bubbles might be included in the high pressure refrigerant; and a supercooling degree control section 19b for when the air bubble determination section 19a determines that there is a possibility that air bubbles might be included in the high pressure refrigerant, reducing heat radiation amount in the condenser 12 so that a supercooling degree SC of the high pressure refrigerant reaches a predetermined reference supercooling degree KSC or higher.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
