Freon™ MO99 can be used to retrofit R-22 heat pumps .
EPA regulations prohibit mixing different types of refrigerants.
No, you should not mix R22 with R134A refrigerant. Here are some key points to consider: Chemical Compatibility: R22 (chlorodifluoromethane) and R134A (1,1,1,2-tetrafluoroethane) have different chemical properties and are not compatible. Mixing them can lead to unpredictable behavior in the refrigeration system.
Freon MO99 is the gold standard for R-22 alternatives and was developed by the same scientists who engineered Freon R-22. The benefits of Freon MO99 include: Capacity — The ability of Freon MO99 to heat or cool a given space is closer to Freon R-22 than any other refrigerant on the market.
Never mix R-22 and R-410a.
Freon™ MO99 can be used to retrofit R-22 heat pumps .
The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur.
Using these retrofit guidelines, many R-22 systems can be retrofitted for use with Freon™ 407C in air conditioning, heat pump applications, and refrigeration applications to allow existing equipment to continue to operate safely and efficiently, even after R-22 is no longer available.
How much will an R-22 to R-410A conversion cost? The actual cost will depend on many things, including where you live, but most of the time R-22 conversions start at around $2,000 and go up from there. The higher end of that range is somewhere around $4,500 to $4,600.
No, the compressor will fail. These two refrigerants have very different properties. One of R22 and R134a is high pressure and the other is low pressure. They don't mix chemically and don't have the same boiling point, leading to inefficiencies and eventual compressor failure.
Having said that, some unscrupulous contractors will top up R22 with a similar refrigerant like R438a in an attempt to save themselves time and money. You simply cannot use an alternative refrigerant to top up a system charged with R22 and no amount of “she'll be right, mate” will ever change that.
There is no such thing as a “drop in” replacement for R-22. Mixing refrigerants is not recommended. R-22 replacements should not be used to top off R-22 systems. R-22 should be recovered using appropriate equipment and managed according to U.S. EPA guidelines specified in Section 608 of the U.S. Clean Air Act.
Can I mix Forane® 427A and R-22? Mixing refrigerants is not recommended as it creates a new refrigerant that is not EPA approved. In addition, it contaminates the R-22. Proper calculation of superheat and subcooling becomes extremely difficult, which could result in damaging the compressor.
As of January 1, 2020, production and import of R22 refrigerant will be illegal in the United States. Of course, continued use of your air conditioner (AC) or heat pump system using R22 refrigerant is allowed.
Compatibility: R32 is compatible with existing air conditioning systems that use R22 and R410A, making it a suitable alternative for retrofitting existing systems. However, it's important to consider compatibility with the specific system and components before retrofitting to R32.
You cannot just switch refrigerants because R410-A and R-22 have different chemical properties. R410-A operates at a higher pressure. If you put R410-A into an R-22 system, the parts will rupture due to the increased force.
Freon™ MO99 refrigerant is a relatively affordable and eco-friendly alternative for R22 air conditioners. You can use it to revive older systems with little to no refrigerant charge, as well as systems that need replacement components.
ACHR NEWS: As a mildly flammable refrigerant, R-454B can't be retrofitted into existing R-22 and R-410A systems.
Freon™ MO29 refrigerant: Extends system life using the same equipment as R-22, so a system with an R-22 leak does not need to be completely replaced or upgraded.
Do not top off a system that contains R-22 with R-422B.
Mixing R22 with R407C or any other refrigerant. According to the 609 EPA rule, mixing refrigerants is illegal and anybody caught doing so will be heavily fined.
When you replace an air conditioner or heat pump and upgrade from R-22 to R-410A, the ideal solution is to replace your refrigerant lines. This is because the mineral oil used in R-22 systems is not compatible with the new R-410A refrigerant and oil.
Since 2010, the most common R-22 replacement was R-410A, a refrigerant without the ozone-depleting qualities of R-22. Read this article on the refrigerant transition for a more thorough explanation of the reasoning and science behind the change.
Since the pressure generated by R410a refrigerant is 1.6 times that of R22 refrigerant, it requires that the copper tube has a large density, strong compressive resistance, high copper tube cleanliness and uniform copper tube wall thickness, so the air conditioning system of R410a refrigerant must use special R410a ...
