Abstract (en)
[Object] It is an object of the present invention to provide a vapor compression refrigeration cycle device wherein when a melting amount of refrigerant into lubricant oil of a compressor is increased, discharge temperature can be increased within a short time after operation of the compressor is started, and a melting amount of refrigerant into oil can be reduced.[Solving Means] The vapor compression refrigeration cycle device of the invention includes a main refrigerant circuit 10, a bypass refrigerant circuit 20 and a control device 50. the control device 50 includes a compressor actuation mode, and in the compressor actuation mode, the control device 50 controls the first expansion device 14 and the second expansion device 21 such that refrigerant flows through both the main refrigerant circuit 10 and the bypass refrigerant circuit 20 for a predetermined period after operation of a compressor 11 is started.
