Title:
SMALL-SIZED REFRIGERATION CYCLE DEVICE
Document Type and Number:
Japanese Patent JP2018119730
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a small-sized refrigeration cycle device which can suppress the lowering of the performance of a heat exchange part while suppressing the enlargement of an arrangement space, related to the small-sized refrigeration cycle device in which a refrigeration cycle having a plurality of parallel flow passages is accommodated in a box body.SOLUTION: In a small-sized refrigeration cycle device 1, a vapor compression type refrigeration cycle 10 is accommodated in a box body 5. The refrigeration cycle 10 has a compressor 11, a heat radiation part 12, a pressure reduction part 13 and a heat absorption part 14. The refrigeration cycle 10 has a branching part 21 for branching a refrigerant from the compressor 11 to a plurality of the refrigerants, a plurality of parallel flow passages 20 in which the refrigerants branched by the branching part 21 flow in parallel alignment, and a merging part 22 for making the refrigerants from a plurality of the parallel flow passages 20 merge with one another, and introducing them to the compressor 11. Each of the parallel flow passages 20 is constituted by serially connecting a first heat exchange flow passage 34 constituting a part of the heat radiation part 12, a pressure reduction flow passage 35 for reducing the pressure of the refrigerant from the first heat exchange flow passage 34, and a second heat exchange flow passage 36 constituting a part of the heat absorption part 14.SELECTED DRAWING: Figure 2
