An R-22 Refrigerant Replacement for Direct Expansion Refrigeration. Freon™ MO29 (R-422D) refrigerant is a low-toxicity, non-ozone depleting
R22 can be replaced with R422B, a cheaper alternative.
410A compressors are totally incompatible with R22 they are mechanically designed different and have different oil the air handler can be used but the metering device, either piston or TXV needs to be changed out to one rated for 410A and system needs flushed and purged out new filter dryers and the works.
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.
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. The production (not use) of R-22 is being phased out.
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.
R-410A PHASE-DOWN TIMELINE
We will reach a 70% decrease by 2029. In 2034, we will see 80% less R-410A being produced than it is today, and the phase-down will end in 2036 with another 5% reduction.
Since R410A refrigerant is charged under higher pressure, charging an R22 system with it will increase the force within the coolant lines. The pressure can become high enough for parts of the system to rupture. At the very least, leaks will occur. Mixing refrigerants is not an option either.
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.
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.
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.
To retrofit an R-22 system with R-410A system your line set must not be more than 25-50 feet in total distance. If the line set is longer than this, you will have to replace the line set with larger lines.
As a solution, there are two alternative refrigerants used as substitute refrigerant for R22, namely R290 and R32. The R290 is widely used as working fluid in A/C system of Europe countries; meanwhile in Japan and South East countries, R32 is utilized as substitute refrigerant for R22 and R410A (Yu et al., 2010).
Freon™ MO99 can be used to retrofit R-22 heat pumps .
R-22 uses simple mineral oil, non-toxic, safe, stable, etc. while R-410a uses a somewhat exotic Poly o Ester (POE) oil typically found in jet turbine engines. The refrigerant used MUST match the oil present in the system, which is one reason why you can't replace the R-22 with R410a in a system.
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.
It is possible to use a different type of refrigerant inside an R-22 system. There are “drop-in” refrigerants that serve exactly this purpose. When someone has an R-22 leak, it's possible to remove all the R-22 from the system and replace it with a drop-in refrigerant.
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.
* Forane® 427A is intended as a retrofit in systems originally designed for R-22. Therefore, how the system was running on R-22 will be a guide or target for how the system should run on R-427A. Compared to R-22, expect 0-5 psi lower on the suction side and 0-10 psi higher on the discharge.
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 ...
If your HVAC system still uses R-22 or R-410A, you don't need to replace or stop using your system right away. The EPA's plan to phase out these harmful refrigerants stretches out into the next decade.
ACHR NEWS: As a mildly flammable refrigerant, R-454B can't be retrofitted into existing R-22 and R-410A systems.
What refrigerant will replace R-410A in 2025? For whole-home systems, Lennox has chosen 2025 Compliant Refrigerant R-454B due to its excellent performance for ducted systems and zero ozone depletion potential. For mini-splits, we selected R-32, designed to optimize efficiency and reliability in ductless systems.
Changes to the Dangerous Goods Legislation, effective in 2021, has new categories for A2L refrigerants. R32 is a synthetic greenhouse gas. If released to the atmosphere it can contribute to climate change. R32 is a flammable refrigerant.
ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems. At 909, RS-53 has a GWP that is effectively 56% lower than R410a. Additionally, RS-51 (R470B) has a GWP of 717 which is 80% lower than R404a, R507 and half of R448A and R449A.
