REFRIGERATION CYCLE DEVICE

The present invention suppresses the generation of vibration and noise caused by discharge pulsation of a compressor. A refrigeration cycle device is provided with: a compressor (11) that sucks, compresses, and discharges a refrigerant; a radiator (12) that dissipates heat from the refrigerant discharged from the compressor; a pressure reduction unit (14a) for reducing the pressure of the refrigerant after heat dissipation by the radiator; and a control unit (60) that controls the opening degree of the pressure reduction unit to a normal opening degree, and when the control unit determines that a liquid-phase refrigerant is stored in the compressor at the time of startup of the compressor, the control unit performs liquid discharge control that promotes discharge of the liquid-phase refrigerant stored from the compressor to the pressure reduction unit. 抑制因压缩机的排出脉动引起的振动及噪音的产生。制冷循环装置具备：吸入、压缩并排出制冷剂的压缩机(11)；使从压缩机排出的制冷剂散热的散热器(12)；使由散热器散热后的制冷剂减压的减压部(14a)；以及将减压部的开度控制为通常开度的控制部(60)，控制部在压缩机起动时判定为在压缩机贮留有液相的制冷剂的情况下，进行液体排
