Title:
REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/182106
Kind Code:
A1
Abstract:
This refrigeration cycle device (1) comprises a compressor (11), a radiator (12), a first decompression unit (15), a first evaporator (16, 16A), a second decompression unit (18), and a second evaporator (19). A refrigerant merging section (20) at which refrigerant that has passed through the first evaporator and refrigerant that has passed through the second evaporator are made to merge is provided on the refrigerant intake side in the compressor. The first decompression unit adjusts the degree of superheating of the refrigerant between the first evaporator and the refrigerant merging section on the basis of a first physical quantity having a correlation with the degree of superheating of the refrigerant flowing between the first evaporator and the refrigerant merging section so that a first target degree of superheating is obtained. The second decompression unit adjusts the degree of superheating of the refrigerant between the refrigerant merging section and the compressor on the basis of a second physical quantity having a correlation with the degree of superheating of the refrigerant flowing between the refrigerant merging section and the compressor so that a second target degree of superheating is obtained.
