Title:
TERNARY MIXED REFRIGERANT, REFRIGERATION SYSTEM, AND REFRIGERATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/098779
Kind Code:
A1
Abstract:
A ternary mixed refrigerant, a refrigeration system, and a refrigeration device, wherein the ternary mixed refrigerant comprises a low-temperature refrigerant, a medium-temperature refrigerant and a high-temperature refrigerant; the mass percentage of the low-temperature refrigerant is 20-40%, the mass percentage of the medium-temperature refrigerant is 20-40%, and the mass percentage of the high-temperature refrigerant is 40-60%; the low-temperature refrigerant is any one of R23, R14, R170 and R1150, the medium-temperature refrigerant is any one of R134a, R290 and R1270, and the high-temperature refrigerant is either of R600 and R600a. The refrigerant is formed by mixing three working media and the ratio of the three working media is regulated and controlled, so that the refrigerant has a relatively low evaporation temperature, and the evaporation pressure is reduced; applying the refrigerant to a single-stage compression refrigeration system can reduce the compression ratio of the compressor (1), lower the technical requirements for the compressor (1), and decrease the throttling loss and the heat transfer loss, so that the temperature in a storage chamber of the refrigeration device can reach -90℃ to -40℃.
