Problems solved by technology

[0003] At present, most of the refrigerants used in domestic air-conditioning or refrigeration equipment are R22. Because R22 can destroy the ozone layer, it has long been included in the list of elimination, and R407C, which replaces R22, has a large temperature glide and is in operation. Exhibiting low energy efficiency restricts its market application

Abstract

The invention provides a quaternary mixed refrigerant and relates to the technical field of refrigerants. The quaternary mixed refrigerant includes: propane, dimethyl ether, propylene and trifluoroiodomethane. In the refrigerant of the present invention, propane, propylene, dimethyl ether and iodotrifluoromethane are compounds that do not contain chlorine atoms, thus will not destroy the ozone layer, and the refrigerant will not produce a greenhouse effect and meet environmental protection requirements, thus becoming an alternative The preferred choice for existing chlorofluoromethane refrigerants.

Description

Technical field[0001]The invention relates to the field of refrigerants, in particular to a quaternary mixed refrigerant.Background technique[0002]Ozone layer depletion and climate warming are environmental problems facing the world today. Over the years, the international community has made unremitting efforts to deal with these two major environmental problems. After reaching a decision in the Montreal Protocol in September 2007 to accelerate the phase-out of HCFCs with high global warming potential (GWP) refrigerants, during the APEC meeting held in Beijing in November 2014, China and the United States issued an announcement to address climate change. The joint statement on changes states that the two countries will strengthen bilateral cooperation in starting to reduce HFCs with high GWP. The U.S. government announced plans to achieve 25% to 28% emission reductions from 2005 in 2025, and the Chinese government announced plans to reduce carbon dioxide emissions around 2030. Reach...
