3-COMPONENT MIXTURE REFRIGERANT USING R32, R1234yf, AND R134a, CAPABLE OF REPLACING HCFC22 AND R410A

摘要

PURPOSE: A 3-componnet mixture refrigerant is provided to prevent the collapse of the ozone layer, have a low global warming potential, and be used as an environmentally friendly refrigerant.;CONSTITUTION: A 3-component mixture refrigerant consists of 20-35 weight% of R32, 0.1-80 weight% of R1234yf, and 0.1-70 weight% of R134a or the 3-component mixture refrigerant consists of 70-90 weight% of R32, 0.1-30 weight% of R1234yf, and 0.1-20 weight% of R134a. The sum of R32, R1234yf, and R134a is 100 weight%. The global warming potential of the R32 is low and the global warming potential of R1234yf is near 0. The compatibility of R134a with the existing lubricant and plastic materials is good.;COPYRIGHT KIPO 2013
