QUESTION: If you were my shoes, would you (1) replace the 20-year old system now, in 2022, with a R-410A system, OR (2) would you wait until Carrier switches all of its models to XL41 (R-454B) refrigerant in January 2023? Why? Relevant Facts: 6000+ Sq ft house Climate Zone 4A
No. R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32. R410A systems are not designed to operate using a flammable refrigerant and would require extensive modification and laboratory validation to confirm that the safety level has been increased to a level that satisfies the requirements of international standards set for
Posted on 8/4/2022. I am getting a new air handler and compressor to replace my old R-22 freon-based units. Can I have the installer just flush out the existing lines before replacing with R-410A refrigerant, or do I have to replace all the plumbing. R32, the main component of R410A, with zero ODP and a relatively low GWP (675), has similar thermodynamic properties with R410A but is less expensive and has been recognized as an attractive short term candidate to replace R22 [1]. 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 mixture is an ozone-friendly alternative to phase out R22 in the existing refrigeration systems to extend its life without modifications. TEGWI of As can be seen in Fig. 3 , the critical pressure of all the identified R32-based mixtures are higher than that of R410A, with a maximum percentage of 27.6% for R32/R1123/R290/R13I1/R41 (20/40/5/30/5). The thermal conductivity of R134a is decreased by 10% compared with that of R22, so the heat exchange area of the heat exchanger of R134a unit is larger than that of R22. The water absorption of
R410A is a 50:50 mixture by weight of R32 and R125. Temperature glide is very small (less than 0.17K). It is the "ozone layer friendly" application replacement for R22 and is used in a variety of air conditioning and refrigeration applications in a variety of markets, including appliance, construction, food processing, and supermarkets.
The phase-out of several common commercial refrigerants is leading building owners to look for greener alternatives. R22, one of several hydrofluorochlorocarbon (HCFC) refrigerants commonly used in commercial air conditioners, cold storage, chillers and retail food refrigeration, is likely to disappear from the market soon.
