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 comprises propane, dimethyl ether, propylene and trifluoroiodomethane. According to the refrigerant provided by the invention, the propane, the propylene, the dimethyl ether and the trifluoroiodomethane are all compounds which do not contain chlorine atoms, sothat the ozone layer is not damaged. The refrigerant does not cause the greenhouse effect, can meet requirements of environment protection, and thus is a good choice for replacing an existing dichlorofluoromethane refrigerant.

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 issues facing the world today. The international community has made unremitting efforts to deal with these two environmental issues for many years. After the "Montreal Protocol" in September 2007 reached a decision to accelerate the phase-out of HCFCs refrigerants with high global warming potential (GWP), during the APEC meeting held in Beijing in November 2014, China and the United States issued a climate change policy. Changes in the joint statement that the two countries will strengthen bilateral cooperation in the reduction of HFCs with high GWP. The US government announced that it plans to reduce emissions by 25% to 28% on the basis of 2005 by 2025. The Chinese government announced that it plans to reduce carbon dioxide emissions around 2030. Reached the peak...
