ComStar's RS-53 (R470A) is the world's only drop-in retrofit replacement for existing R410a systems. At 909, RS-53 has a
What are my options for replacing R-410A? Because there are no retrofits for R410A, a replacement is needed. The replacements for R-410A are the two A2Ls, Forane® R-32 and R-454B. Forane® R-32 can be used in new equipment designed specifically for mildly flammable refrigerants as a replacement for R-410A equipment.
Air conditioner and heat pump manufacturers are rolling out new refrigerants to comply with EPA guidelines. Starting in January 2025, no new HVAC systems will use R-410A refrigerant. Instead, most residential systems will use either R-32 or R-454B refrigerant, both of which have a comparably lower environmental impact.
R32 is not suitable as a drop-in replacement for R410A and must only be used in systems specifically designed for R32.
R32, R452B, and R454B replacements for R410A are all classed as 2L: mildly flammable. These A2L refrigerants offer only moderate limitations in charge for direct expansion systems and no limitations for indirect expansion systems such as chillers, when located outdoor or in technical rooms.
RS-53 (R470A) is a new non-flammable Drop-in replacement for R410A with a low Global Warming Potential (GWP) less than half that of R410A. RS-53 (R470A) has a similar thermodynamic performance to R410A with matching energy efficiency and cooling capacity.
In December 2022, the EPA unveiled a refrigerant ban that will go into effect between 2025 and 2026 (depending on the industry). The result? R-410A is out, shaking up the HVACR industry, which relies heavily on this refrigerant.
What is the replacement for R-410A? A lower GWP replacement for R-410A is Forane® R-32. Forane® 32 is a stand-alone third generation refrigerant for new residential and light commercial air conditioning systems, heat pumps and other HVAC applications.
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.
R32 has a higher compressor discharge temperature than R410A, and will increase wear on the compressor, reducing its life significantly. Should any problem arise from a system change such as this, any liability would rest ENTIRELY with the person who carried out the change.
When Will R-410A Be Phased Out Completely? The complete phase-out of R-410A will likely occur by 2036, when HFC consumption is expected to be reduced by 85%. However, businesses should prepare well in advance, as the restrictions beginning in 2025 will already limit its use significantly.
Will R-454B work in existing R-410A systems? No. R-454B is NOT a drop-in replacement for R-410A. Although many of the characteristics of R-454B are similar to R-410A, the use of R-454B is restricted by code and regulation to systems for which it was specifically designed.
Regulatory Changes: As the phase-out continues to restrict production levels and importation, the R-410A price will likely increase. Manufacturing Costs: Fluctuations in the cost of raw materials and manufacturing can also influence the price of refrigerants.
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.
Trane is phasing in the transition to R-454B in 2024, starting with the adoption of R-454B refrigerant in its residential products, beginning with the XR15 SEER2 heat pump.
A refrigerant handling licence is required when using R32 refrigerant, and a refrigerant trading authorisation is required to acquire, possess and dispose/sell it.
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.
So what the manufacturer recommends, the best option, is if you're going to go from an R22 unit to an R410 unit, that you should have your line set replaced at the same time. So everything is new. There's no contamination, there's no possibility of contamination.
An environmentally more benign refrigerant for replacing refrigerant R410A includes a majority portion of refrigerant R32 and a minority portion of refrigerant R134a, the volumetric capacity of the replacement refrigerant permitting it to be used as a near or exact drop-in replacement for refrigerant R410A in terms of ...
Because its properties and performance match those of R-410A, Opteon™ XP41 is an ideal replacement. Other properties that make it adaptable for its many uses include the lowest GWP of 1377—30% lower than R-410A—and an A1 nonflammable ASHRAE safety rating.
In most cases, R32 is the superior refrigerant when compared to R410A. While neither refrigerant depletes the ozone layer, R32 has a lower GWP and is easier to recycle. R32 also has lower operating and maintenance costs and is nowadays more common than R410A due to the phase-out.
This hydrofluorocarbon (HFC) refrigerant is compatible with polyolefin (POE) oils and replaces R-22 in positive displacement air conditioning (AC) and heat pump systems for residential and light commercial use.
Yes, R-410A will still be available for maintenance and repairs for many years. R-410A won't actually be phased out of production until the 2040s. Also, contractors can still reclaim and reuse refrigerant from older systems.
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. This will contaminate the system, and the R22 will not evaporate under the higher suction pressure that R410A requires.
This means that – in most cases – R-454B is not a direct drop-in replacement for R-410A. Only looking at COP may indicate otherwise, but capacity must also be considered. Our test data indicates that R-454B coils will require 10 – 20% additional heat transfer surface to meet the same capacity as and R-410A design.
