Abstract

The invention discloses an environment-friendly mixed refrigerant. The refrigerant comprises the following components, in percentages by mass: 1%-90% of a first component, 1%-90% of a second component, 1%-90% of a third component and 1%-97% of a fourth component, wherein the first component is trifluoroiodomethane, the second component is at least one selected from 1,1,1,2-tetrafluoroethane and pentafluoroethane, the third component is at least one selected from trans-1,3,3,3-tetrafluoropropene, 2,3,3,3-tetrafluoropropene and difluoromethane, and the fourth component is at least selected from1,1-difluoroethane, monofluoroethane, propylene, propane, dimethyl ether and isobutane. The GWP value of the mixed refrigerant provided by the invention is greatly reduced relative to R404A, the ODP is 0, and the environmental performance is better than that of the R404A.

Description

technical field

[0001] The invention relates to a refrigeration working medium, in particular to an environment-friendly mixed refrigeration working medium. Background technique

[0002] At present, with the global warming and the deterioration of the ecological environment in recent years, the international community has formulated a series of laws and regulations to limit the use of high global warming potential (GWP) refrigerants, and to replace high GWP refrigerants Higher requirements have been put forward, requiring new refrigerants to have zero ozone depletion potential (ODP) and the lowest possible GWP value. The Kigali Amendment to the Montreal Protocol adopted in 2016 has formulated a more stringent reduction plan for high-GWP refrigerants. As a contracting country, China will achieve the goal of 80% reduction (calculated by CO2 equivalent) in 2045. Therefore, it is imminent to research and develop environmentally friendly refrigerants with low GWP value. Due to ...
