REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2014/049928
Kind Code:
A1
Abstract:
A refrigeration cycle device that has, between a radiator (14) and an accumulator (17), a first evaporator (16) for cooling a first object to be cooled and a second evaporator (20) for cooling a second object to be cooled disposed in parallel, a first decompressor (15) disposed upstream of the first evaporator (16), and a mechanical expansion valve disposed upstream of the second evaporator (20) as a second decompressor (19), is configured to comprise a refrigerant channel (18) in which a portion of the refrigerant flowing from the radiator (14) flows by bypassing the second decompressor (19) and the second evaporator (20), and that returns the refrigerant containing liquid phase refrigerant to the accumulator (17) by reducing the pressure by way of the decompressor (15), that is different than the second decompressor (19), while in cooling operation mode to cool only the second object to be cooled that is for cooling both the first and second objects to be cooled, only the first object to be cooled, and only the second object to be cooled, respectively.
