So… what refrigerant can be mixed with R-22? None. You can't mix refrigerants.
Rs44b can be mixed with r22.
Freon MO99 is the closest capacity match to R-22, compared with most other no-oil change refrigerants.
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.
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.
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.
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.
Heating mode The compressor pressure ratio of R-407C was 0.7% to 9.3% higher than R-22 for the two heating mode test conditions.
The information below will try to dispel some of these myths. Arkema recommends using Forane® 427A (R427A) - The EASY RETROFIT™ for your r-22 retrofit solution. When it comes to drop-ins, the truth is that there are none. The hope of “drop-in” refrigerants has become common over the years.
R417A refrigerant is an HFC mixture that serves as a substitute for R22. It is compatible with traditional lubricants. In most cases, the lubricant type does not need to be changed in the event of retrofitting.
On January 1, 2020, the U.S. Environmental Protection Agency (EPA) banned the production and import of R-22. But units manufactured in 2009 and earlier still use R-22 today. Its use will eventually be eliminated in the U.S., so all current and future homeowners must be prepared for the transition.
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.
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.
The biggest problem of using refrigerant R404A to replace refrigerant R22 is the problem of lubricating oil. PVE ester oil must be used to replace the mineral lubricating oil for R22. Ester lubricants have high affinity with water and poor dehydration.
R-438A should not be mixed with any other refrigerant! Demand Cooling™ is required for low temperature applications. 5. When retrofitting from R-22 to R-438A, the expansion valve will likely not require replacement; however, it is recommended that the valve loadings be evaluated to verify that they are adequate.
So… what refrigerant can be mixed with R-22? None. You can't mix refrigerants.
If your system is running on R22 most likely is using mineral oil to lubricate the compressor. If you mix R407C with R22 inside your system the molecule of the HFC (R407C) gas will not link with the oil and in just few months of operation you will have a "sludge" like lubricant formation inside the circuit.
Never mix R-22 and R-410a. Unless of course you are looking to destroy your HVAC system, then, by all means, go live that dream.
Because R-22 depletes the ozone layer, production and import was further limited in 2010. In 2020, R-22 will no longer be produced or imported. After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available.
Features and Benefits. Freon™ 407C has been a popular R-22 replacement because of its properties, which include: Similar cooling capacity, energy efficiency, and pressures as R-22 in systems. An ability to be topped off after a leak, multiple times, with minimal impact on system performance.
Among those products is Freon™ MO99™ (R-438A), a retrofit refrigerant for R-22 that does not require an oil change. Freon™ MO99™ works with: Residential and commercial air conditioning systems (rooftop and indoor packages units, direct expansion chillers, split systems)
R410A is the most common, but others include R134a, R407C and R407A. These refrigerants cool interior spaces just as effectively as R22 with no ozone depleting characteristics and relatively low Global Warming Potential (GWP).
R-1234yf systems that control freeze protection by pressure may encounter loss of cooling performance if charged with 100% R-134a. This is due to the requirement of R-134a to have a lower setting of 3.3 psig to achieve freeze protection at 32 F. This may result in a 4-degree F.
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.
