R32/R134a is a zeotropic mixture with a high temperature glide, so the refrigeration cycle differs from pure fluids. The 30/70 R32/R134a mixture can be a candidate alternative refrigerant to replace R22 from a theoretical analysis [24]. Mixtures are also being investigated experimentally.
Freon™ MO99 is the closest match to R-22 of all "no oil change" replacement refrigerants. It is compatible with all traditional and new lubricants. Compare MO99 to other R-22 replacement products. Freon™ MO99 matches R-22 in terms of capacity and efficiency in most systems, but with a significantly lower discharge temperature that may
R32A, R452B and R454B replacement for R410A R410A is the most commonly used refrigerant in air conditioning, reversible chillers, heat pumps, close control systems. However, established F-Gas regulation leads the use of refrigerants with low GWP as long-term solution. R32, R452B and R454B are mildly flammable A2L refrigerants with low GWP as
The refrigerant is a HFC blend consisting of five components. They include 8.5% of R32, 45% of R125, 44.2% of R134A, 1.7% of Butane (R600A), and 0.6% of iPentane (R601A). HVAC technicians usually use R438A as a retrofit replacement for R22. Retrofit replacements require the technician to change the system’s components, including the lubricant

Recently, Ramu et al [13] proposed the refrigerant mixture R32/R125/R600a (in the ratio of 0.4:0.4:0.2, by mass) to be used in air conditioners to replace R22 and reported that the new refrigerant

What this means is that a system designed to use R-22 will fail quickly if filled with R-410A, and vice versa. For instance, R-410A builds up system pressure on the high-pressure side that is 50 percent greater than R-22, putting overwhelming strain on the compressor, lines and seals. If the R-410A lubricant encounters traces of the R-22
R22 is accepted as the most suitable refrigerant but it will be phased out as per the schedule. [1-7] 2. Alternatives to R22 Suggestive alternatives to R22 are R134a, R290 (Propane), R407C and R410A. R407C and R410A are a zeotropic blend of R32/R125/R134a (23/25/52 by wt %) and R32/R125 (50/50 by wt %) respectively. It is suggested that acid
