Title:
DUAL-ELEMENT MIXED REFRIGERANT, DUAL-ELEMENT MIXED WORKING MEDIUM REFRIGERATION SYSTEM, AND REFRIGERATION APPARATUS
Document Type and Number:
WIPO Patent Application WO/2023/098778
Kind Code:
A1
Abstract:
Provided in the present invention are a dual-element mixed refrigerant, a dual-element mixed working medium refrigeration system, and a refrigeration apparatus. The dual-element mixed refrigerant comprises a first working medium and a second working medium, wherein the mass percentage of the first working medium is 10-60%, the mass percentage of the second working medium is 40-90%, the first working medium is one of R170, R1150, R23 or R14, and the second working medium is any one of R290, R600, R600a, R134a, R1234yf or R1234ze. By means of the present invention, the temperature in a compartment can reach -90°C to -40°C, and the power consumption and noise are reduced; moreover, when a refrigerant is applied to a single-stage compression refrigeration system, the intensity of pressure between an outlet of a compressor and an inlet of a capillary tube during stable operation can also be controlled to be within a bearable range of the compressor.
