Document Type and Number:
Japanese Patent JP2020201012
Kind Code:
A
Abstract:
To reduce a filling refrigerant amount of a refrigerant cycle system.SOLUTION: A refrigerant cycle system 100 includes: a primary side cycle 20 for circulating a first fluid; a secondary side cycle 40 for circulating a second fluid; and a cascade heat exchanger 35 for exchanging heat between the first fluid and the second fluid. The secondary side cycle 40 includes: a secondary side heat exchanger 51; a decompression device 52 for decompressing the second fluid; and a switching device 34 for switching the direction of the circulation of the second fluid. A first volume V1, which is the volume of the secondary side heat exchanger 51, and a second volume V2 which is the volume of a second fluid passage 352 of the cascade heat exchanger 35 satisfies the relation: 0.80≤V1/V2≤1.20.SELECTED DRAWING: Figure 1
