Evaluation and Safety of HC Refrigerants Used in VCR System

Abstract

Abstract There is no ozone depletion or global warming with HC (Hydro Carbon) refrigerants, although they are extremely combustible. New freezers in Oman employ R600a, and many warm-temperature pumps and air conditioners now use R290, which consumes 5 to 25 percent more electricity than R-12, R-134a, or R-22 (CFC) (HCFC). A/C systems that use the refrigerants R-12 and R-134a have been successfully adjusted using HC combinations (AC). R-12, a chlorofluorocarbon refrigerant, is needed to combat ozone depletion and global warming. There is no ozone depletion or global warming with R-134a hydrofluorocarbon since it is nonflammable and difficult to distribute. Using R-12 and then HC, we measured the total AC performance of five different samples in our lab. 60 percent of propane and 40 percent of butane come from the general market. This provided an average of 15% more cooling capacity than R-12, despite the higher superheat and, on average, 10% better condenser pressure.
