Is R421A a good replacement for R-22?
EPA Number R-421A is a drop-in replacement for R22 systems. With this refrigerant there is no need to change the oil. Simply recover the R22 and recharge with R421A.
What refrigerant does R421A replace?
R-421A is an ASHRAE-designated, SNAP approved non-ozone-depleting R-22 replacement consisting of R-125 and R-134a. It is the only 2-component R-22 replacement available today.
Can you mix r438a with R-22?
Mixing refrigerants is never recommended. However, based on the similar operating conditions of Freon™ MO99 and R-22, system damange would not be expected.
Can you top off R-22 with MO99?
Freon™ MO99 is the closest match to R-22 of all “no oil change” replacement refrigerants. MO99 is compatible with mineral oil and POE oil providing a quick, cost-effective R-22 replacement, and can be topped off during service without removing the entire refrigerant charge.
What freon can you use to replace R22?
R-407c
The best replacement for R-22 Freon is usually R-407c. It has a very low loss in capacity (0 – 5%) relative to R-22 and is less expensive than many other R-22 replacement refrigerants. If a system has R22 in it already you cannot use a replacement refrigerant to simply add to the R22.
What refrigerant is being used to replace R22?
So let’s see what is the replacement for R22 refrigerant which can be used with the air conditioning compressor and with flooded evaporators. R-410A is the replacement for R22. It is known as Suva 410A, Puron, Genetron R410A, AZ-20, Forane 410A and EcoFluor R410.
What is the R22 refrigerant being replaced with?
As we mentioned above, R22 refrigerant is being replaced by a refrigerant called R410a. Unlike R22, the use and manufacturing of R410a does not deplete the ozone layer. However, cooling systems that currently use R22 refrigerant cannot operate with R410a.
Is there a replacement for R22 refrigerant?
HFC (hydrofluorocarbon) refrigerants are among the suggested replacements for R-22 since they have zero impact on ozone depletion. The EPA has compiled a list of alternative refrigerants to the ozone depleting group of refrigerants and the proper applications for their use in their Significant New Alternatives Policy (SNAP) Program.
