Abstract

The invention relates to a ternary mixing refrigerant used in an air-conditioner / heat-pumping system, wherein the ternary mixing refrigerant comprises, by mass, 10-40% of 1,1,1,2-tetrafluoroethane, 10-40% of 2,3,3,3-hexafluoropropylene, and 20-50% of propane. According to the present invention, the thermodynamic properties of the refrigerant of the present invention are similar to the thermodynamic properties of R407C, such that the R407C can be replaced through the direct filling of the ternary mixing refrigerant after the original R407C system is slightly changed so as to provide the low replacement cost; and the ternary mixing refrigerant has advantages of environmental protection and good circulation performance compared to the R407C so as to be used as the ideal R407C substitute.

Description

technical field [0001] The invention belongs to the field of chemical industry and relates to a refrigerant, in particular to a ternary mixed refrigerant used in an air conditioner / heat pump system. 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...
