Learn how Freon™ MO29 can be used as a non-ozone depleting hydrofluorocarbon (HFC) refrigerant replacement for R-22 in a variety of applications. Do What refrigerant can mix with R22? The most commonly mixed refrigerants in the field are the replacements for R-22 — R-427A, R-438A, R-422D, and R-407C — which are often combined When considering retrofitting R22 with R422D, it's important to follow established procedures. Just wanted to get some opinions Here is an article Understanding what refrigerants can mix with R22 is critical for anyone wanting to maintain their cooling systems or transition to newer alternatives. 2. R410A systems operate at much higher pressures than R22 systems, typically by 50-60%. The hydrocarbon component in R422D helps promote oil return in systems containing mineral oil or alkylbenzene. The refrigerants have very different heat-transfer properties and use chemically incompatible lubricating oils, so they aren't interchangeable and can't be mixed. This typically involves recovering the existing R22 charge, evacuating the system thoroughly, Learn how Freon™ MO29 can be used as a non-ozone depleting hydrofluorocarbon (HFC) refrigerant replacement for R-22 in a variety of The hydrocarbon component in R422D helps promote oil return in systems containing mineral oil or alkylbenzene.

To learn more about R422D visit our landing page at http Retrofitting Older R22 Systems If you have an older system that uses R22 refrigerant, you can either upgrade to a newer R410A system or retrofit the One of the most significant reasons you cannot use R22 refrigerant in an R410A unit is the operating pressure. su Can you mix R22 and R410A together? And since this is almost twice the pressure that the R22 liquid requires to evaporate, R22 clearly cannot evaporate in an environment where the higher-pressure Can you mix 422D with R22? R422D is a so called drop in for R22. You must remove the R22 and replace the whole charge with the R422D. Although HFC refrigerants won’t mix with these oils, the hydrocarbon component thins R422D is quickly becoming a popular substitute for R22. Any refrigerant mixing creates a non-reclaimable mixture that will cost you or your customer more money in disposal fees.
