Title:
BINARY REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/224382
Kind Code:
A1
Abstract:
This binary refrigeration cycle device (51) comprises a first high-temperature refrigerant circuit (100) for circulating a first refrigerant, a second high-temperature refrigerant circuit (200) for circulating a second refrigerant, a low-temperature refrigerant circuit (300) for circulating a third refrigerant, a first cascade capacitor (104), and a second cascade capacitor (204). The first high-temperature refrigerant circuit (100) has a first compressor (101), a first heat exchanger (102), and a first expansion valve (103). The second high-temperature refrigerant circuit (200) has a second compressor (201), a second heat exchanger (202), and a second expansion valve (203). The first high-temperature refrigerant circuit (100) and the second high-temperature refrigerant circuit (200) are configured to have mutually different maximum cooling capabilities.
