Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/079852
Kind Code:
A1
Abstract:
A refrigerant circuit (1) includes a compressor (11), a four-way valve (12), a first heat exchanger (13), a first expansion valve (14), a second expansion valve (24), a second heat exchanger (25), and internal heat exchangers (15) and (16). The internal heat exchangers (15) and (16) exchange heat between a first flow path through which refrigerant flows between the first expansion valve (14) and the second expansion valve (24), and a second flow path through which the refrigerant flows between the four-way valve (12) and the compressor (11). The second flow path is configured such that the refrigerant branches, exchanges heat, and then merges. The number of branches in the second flow path is greater than the number of branches in the first flow path.
