Document Type and Number:
Japanese Patent JP2016156554
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To enable air-conditioning of a second air-conditioning space, in a refrigeration cycle which can air-condition a first object space by a wide operation mode.SOLUTION: A refrigeration cycle device includes: a heat exchanger 44 for a second object space for exchanging heat between a refrigerant and blowing air to a second object space 49, and for evaporating the refrigerant flowed out of an outdoor heat exchanger 15; a first branch flow passage 26 for guiding the refrigerant to the heat exchanger 44 for a second object space from between an outlet side of the outdoor heat exchanger 15 and a second expansion valve 19 in a third refrigerant passage 18; mechanisms 28, 29 for opening/closing the first branch flow passage 26 and for decompressing the refrigerant flowed in the first branch flow passage 26 from the third refrigerant passage 18; and a second branch flow passage 27 for guiding the refrigerant flowed out of the heat exchanger 44 for a second object space to a suction side of a compressor 11 from a constant-pressure valve 25 of the third refrigerant passage 18.SELECTED DRAWING: Figure 1
