R-32 is the most balanced refrigerant in terms of environmental impact, energy efficiency, safety, and cost-effectiveness. Refrigerant is a medium for conveying heat. Air conditioners transfer heat while circulating refrigerant between the indoor and outdoor units.
R-32 is the most balanced refrigerant in terms of Environmental Impact/Energy Efficiency/Safety/Cost-Effectiveness for Stationary Air Conditioners and Heat Pumps.
Ammonia surpasses HFC/HCFC refrigerants in terms of performance as it provides the same cooling with lower power consumption and system costs. Ammonia has high latent heat that permits the use of small-sized liquid line pipes, eventually reducing the system volume of refrigerant required.
R410A has a high VCP, which requires larger pipes. Thus, it's not as efficient as R32, whose VCP is significantly lower. Moreover, R32 has a higher pressure ratio than R410A. Overall, R32 is much more efficient than R410A.
After being banned for further use back in 2004, it is now illegal to use virgin, recycled and reclaimed HCFCs during servicing, maintenance and repair. The main reason that the R22 refrigerant was banned is due to its effect on the ozone layer.
The F-Gas regulations are a phase down (not out) of higher GWP refrigerants. R410A equipment will still be readily available to buy. R32 will be introduced and will run alongside R410A equipment for the coming years.
R32 has the advantage of being a singlecomponent refrigerant with higher energy efficiency and a smaller physical footprint. It's already in use globally, so you can be confident in its reliability. R454B, while newer, has the benefit of an even lower GWP, making it the more environmentally friendly option.
Damage to system: Using the wrong refrigerant can cause your system to malfunction or even break down, which can significantly reduce its life span. Voiding warranties: Using a refrigerant other than the one intended by the manufacturer will automatically void your warranty in many cases.
UK to ban sales of R410A single split AC units from 1st January.
As R-410A is phased out, A2L refrigerants are emerging as the primary alternatives due to their lower Global Warming Potential (GWP) and reduced environmental impact. Refrigerants like R-32 and R-454B are leading the charge, offering a GWP that is significantly lower than R-410A.

There are two key disadvantages to using ammonia as a refrigerant: It is not compatible with copper, so it cannot be used in any system with copper pipes. Ammonia is poisonous in high concentrations.
Medium Deep Freezers, 43 X 26 X 34, Refrigerant Used: R-134A.
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.
Disadvantages:Different from R22 and R410A, the R32 is slightly flammable. But combustion will not occur unless three critical conditions are met, refrigerant concentration, constant oxygen, and an ignition source. In real practice, it's hard to meet all the combustion conditions.
R-134a refrigerant, also known as Tetrafluoroethane, is a popular choice for commercial refrigeration systems due to its low toxicity and non-flammability. It is commonly used in medium- and high-temperature applications, such as refrigerators, air conditioning units, and chillers.
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.
Servicing is not due to be phased out until 2030. Alternative lower GWP refrigerants include R449A, R448A, R452A and A2Ls R454C and R455A. New installations using R134a will be banned from use in refrigeration in 2022, with R1234ze, R450A and R513A alternative options.
If you have a high-capacity AC installed in your home or your business, you must get it assessed every five years. The goal of an accredited air conditioning energy assessor's evaluation is to increase efficiency, lower energy use, operating costs, and carbon emissions.
HVACR body FETA has warned the industry not to attempt to retrofit R32 to R410A systems, arguing the practice is not just unsuitable for the system, but poses serious safety risks.
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. Its low density allows for the use of a smaller refrigerant charge.
In the figure, the notation such as R32 + R134a (90/10) indicates that R32 is a mixed refrigerant of 90 wt% and R134a is 10 wt%. As shown in FIG. 3, it can be seen that mixing R134a (or R1234yf) with R32 suppresses the discharge temperature.
Next Generation Refrigerant
Daikin's next gen refrigerant, R-474A, with a GWP<1 is specifically designed for electric vehicles (EV) and delivers increased cooling and heating capacity with superior efficiency.
Exposure hazards: Flammable. In combustion emits toxic fumes. Forms explosive air-vapour mixture. Advice for fire-fighters: Wear self-contained breathing apparatus.
A refrigerant handling licence is required when using R32 refrigerant, and a refrigerant trading authorisation is required to acquire, possess and dispose/sell it.
