Title:
BINARY REFRIGERATION CYCLE APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/224383
Kind Code:
A1
Abstract:
A binary refrigeration cycle device (51) comprises a first high-order refrigerant circuit (100) that circulates a first refrigerant, a second high-order refrigerant circuit (200) that circulates a second refrigerant, a low-order refrigerant circuit (300) that circulates a third refrigerant, a first gasket capacitor (104), a second gasket capacitor (204), and a control device (30). The first high-order refrigerant circuit (100) has a first compressor (101), a first heat exchanger (102), and a first expansion valve (103). The second high-order refrigerant circuit (200) has a second compressor (201), a second heat exchanger (202), and a second expansion valve (203). The control device (30) varies the cooling capacities of the first high-order refrigerant circuit (100) and the second high-order refrigerant circuit (200) on the basis of the state of the refrigeration cycle of the low-order refrigerant circuit (300).
