Several refrigerants are out with similar properties to R-22. Lately, the most notable one is R-410A, though it`s properties are not so close to 22 it is getting a lot of traction as the long term replacement. Another is 407C, but it never gained the popularity that 410A has. Probably because it is a blend and will fractionate. There is no drop in replacement for 22 that I am aware of and if there is it is not widely promoted or used.
ef22a is a refrigerant. It is used in place of R22. It is a Hydrocabon refrigerant. Very efficient.....
407C is a refrigerant that is often used as a replacement for R22, particularly in systems designed for R22. While it is compatible in terms of functioning within the same system, it is important to note that 407C operates at slightly different pressures and requires a different oil type (POE oil instead of mineral oil). Therefore, a system designed for R22 may need some modifications to ensure optimal performance with 407C. Always consult a professional before making any changes to refrigerant types in HVAC systems.
It is an alternative to mostly banned CFCs (most infamous of which is R22), and to be phased out in the future HFCs (R410a, R134 and similar). That being said the general consensus is that R600a (isobutane) requires compressors/systems specifically designed for it. The most suitable HC or natural refrigerant substitute for R22 is R290, which although shunned by the industry will perfectly replace it with an efficiency increase of about 20% without any retrofitting or other adjustments.
Wal-Mart do not have r22 freon, this is a false ad.
