It is concluded that R458A performs well as a drop-in alternative refrigerant to R22 and surpasses that of R453A, as it showed slightly less deviation in coefficient of performance.
R458A also serves as a true R22 replacement; no further modifications are required for use. R458A works to improve the overall performance of refrigeration and HVAC systems while reducing energy consumption.
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.
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)
The industry-wide phaseout of R-22 to meet mandates to reduce high ozone-depleting potential (ODP) refrigerants depends on alternative options such as Freon™ MO29. This nonflammable HFC alternative offers a host of benefits that include: Cost-effective retrofits (and easier retrofitting) than R-404A, R-507, and R-407C.
Freon™ MO99 can be used to retrofit R-22 heat pumps .
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.
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.
R-438A provides similar cooling performance and energy efficiency to R-22 in most systems, while operating at a lower compressor discharge temperature and similar evaporator and condenser pressures.
R438A (Freon™/Isceon MO99) is a HFC blend, used as a replacement for R22 in domestic, industrial and commercial air-conditioning systems.
So… what refrigerant can be mixed with R-22? None. You can't mix refrigerants.
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.
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.
You should not mix R-22 with any other refrigerant.
TdX 20 (R-458A) is the groundbreaking. R-22 replacement with real support.
Accordingly, R453A or R458A can be employed to replace R22 in both air conditioning and refrigeration applications across the temperature range, where R22 is generally used.
RS-44 is a “Drop-in” replacement for R22 providing an easy and at the same time a long term solution. Because there is no need to use expensive and hygroscopic synthetic lubricants, the risk of moisture ingress into a refrigeration system is completely avoided.
R-438A is versatile and can be used for retrofitting R-22 direct expansion (DX) systems in air conditioning applications (high temperature) and medium- and low-temperature refrigeration applications.
Refrigerant R-22 has been successfully used with mineral oil in residential air-conditioning and heat pump systems (AC/HP).
R-438A is a non-ozone depleting hydrofluorocarbon (HFC) refrigerant blend which can be used to retrofit existing hydrochlorofluorocarbon (HCFC) refrigerant R-22 refrigeration and air conditioning systems with direct expansion evaporators and positive displacement compressors.
Freon™ MO99 is U.S. EPA SNAP-approved, compatible with mineral oil and POE, and has the closest performance match to R-22 compared to other “no oil change” replacements.
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.
If you do have to replace the gas in your air con, you should use an approved hydrofluorocarbon (HFC) alternative. The most common HFC refrigerants used as a replacement for R22 include: R134a. R404a.
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.
