R134 is a member of the more recent generation of hydrofluorocarbon (HFC) refrigerants that has replaced older, ozone-depleting chemicals, such as R22 and R12. R134 was specifically designed to replace R12 used in smaller air conditioning units, such as those used in vehicles. R134 is also used in home appliances, mobile refrigeration units and
High SEER R22 units are no longer made, and only carry their ratings when installed with matched equipment. Putting a 16 SEER outdoor unit on a 10-15 year old coil doesn't equal 16 SEER efficency. The only high SEER units now are R410A. These cannot use R22 and cannot be used with an indoor coil that's only rated for R22.
Montreal Protocol, governments agrees to advance the final phase out date for HCFCs. The replacement of refrigerant for the environment protection is always happening. Up to now, R134a, R407C, R410A and R22 are the refrigerant most widely used in the world on A/C application R22 is only limited in developing countries and the
For example, R-134a has one of the lowest, with a GWP of 1,430. Replacement options for R-22 systems have included higher GWP gases such as R-407A (GWP of 2,107) for grocery stores and R-410A for air conditioning systems (GWP of 2,088). Businesses need to be informed to make the best choices when purchasing new systems.
R-22 is an HCFC refrigerant and can harm the Ozone layer. It was originally invented by a partnership with General Motors and the DuPont company all the way back in the 1930’s. These new CFC and HCFC refrigerants were known under the DuPont brand name Freon. R-22, along with it’s sister product R-12, were one of the first mainstream
50% of R32 and 50% of R125 No chlorine content, no ozone depletion potential. ODP = 0 Global warming potential GWP = 1725: R-417A: R417A is the zero ODP replacement for R22 Suitable for new equipment and as a drop-in replacement for existing systems. R-500: CCl 2 F 2 (73,8%) CH 3 CH F 2 (26.2%)-33: Similar to R12
Unlike the substitutes for R22 in refrigeration systems with identical blend components (R407A/B/F/H as substitutes and R422A as substitute), the substitutes for R22 in air conditioning systems and heat pumps contain higher proportions of R32 and R134a. A good correspondence with the properties of R22 in terms of pressure levels, mass flow

can i replace r22 with r32
