Abstract
In a refrigeration cycle device, a first evaporator for cooling a first cooling target and a second evaporator for cooling a second cooling target are arranged in parallel between a radiator and an accumulator, a first pressure reducer is arranged upstream of the first evaporator, and a mechanical expansion valve as a second pressure reducer is arranged upstream of the second evaporator. The refrigeration cycle device includes a refrigerant passage through which a portion of a refrigerant flowing out of the radiator flows while bypassing the second pressure reducer and the second evaporator, and is decompressed by a separate pressure reducer from the second pressure reducer, so as to return the refrigerant containing a liquid phase refrigerant to the accumulator, in a cooling operation mode for cooling only the second cooling target.
