R-1234yf in particular is often seen as a possible alternative to R-134a. The
Comments Section R600a is a replacement for 134a. It has a smaller molecular weight and can therefore allow an engineer to use a compressor with a lower displacement. It is flammable so engineering of the system requires the electronics and switching to be kept separate from the refrigerant piping.

According to its manufacturer, Chemours, use of R-1234yf has grown so much since the refrigerant replaced the long-established R-134a that it's now used in 95% of new cars sold in the U.S. An estimated 220 million cars on global roads are also using it.
A Next-Generation R-134a Refrigerant Alternative
Opteon™ XP10 (R-513A) refrigerant is a non-ozone depleting potential (ODP), low global warming potential (GWP) hydrofluoroolefin (HFO) based replacement for R-134a.
With the scientific approach to reduce the global warming potential (GWP) of the refrigerant R-134A (i.e. 1430), the refrigerant R-513A with GWP of 631 is the drop-in replacement.
While R-1234yf could be the perfect replacement for R-134a, there is one major challenge with this new technology. The R-1234yf is much more reactive than R-134a. On the positive side, this higher reactivity is why R-1234yf is so much more friendly to the environment.
As part of global efforts to reduce the environmental impact of refrigerants, R134a will be phased out by 2025 in favor of more eco-friendly alternatives like R290 and R1234yf12.
Also, substitutions are often not without problems. For example, when replacing R22 with R134a, there are many problems that cannot be replaced directly; the cooling power of R134a is 60% lower than that of R22, which means that the condenser of the system must work overtime to achieve the same cooling capacity.
R32 and R152a have a reduced global warming potential than R134a, which indicates that R32 can be used as substitute for R134a in refrigeration systems.
“ R-1234yf is an even more environmentally-friendly gas than R-134a and has been making its way into some cars since 2013. MOTOR Selectline.
The commonly used synthetic refrigerants such as R134a, R407C and R410A have a GWP value higher than 2,500. As a result, their production is being phased out.
R134a is a safer replacement for R12. Another major difference is the type of oil both refrigerators require. R12 is compatible with mineral oil, and most R12 systems use this. R134a uses Polyalkylene Glycol (PAG) oil.
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 ...
R-513A – also known as Opteon, it is a next generation non-ozone depleting, low global warming potential hydrofluoroolefin (HFO) that replaces R-134A. R-600 – an efficient natural refrigerant suitable for refrigeration applications. It is environmentally friendly and efficient.
Yes all R134 Freon is considered 134 A and you will be fine topping the system off with R 134A.
The GWP for R-134a refrigerant is 1,430, making it 1,430 times more harmful than carbon dioxide when released into the atmosphere. There are three refrigerants that can be used to replace R-134a: R-1234yf, R-152a, and R-744.
The R407c refrigerant is the best suitable for R22 and R134a refrigerant in the future construction of the heat pumps. As the complete replacement of refrigerant needs system redesign, In the current work R407c has been blended with R134a and the performance and energy consumption patterns are studied.
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.
Still, the answer is an emphatic, “No.” Not only would a retrofit of this type negate the environmental benefits of R-1234yf, but it would also be a violation of Federal Law under Section 203 of the Clean Air Act: “tampering” with a vehicle's emissions control device.
The chemical stabilities of copper, steel, and aluminum have been tested and confirmed as acceptable for use with Freon™ 134a and lubricants. Acceptable plastics and elastomers have been found for use with existing CFC refrigerants.
Comparing the heat pump performance of the several operating refrigerants, it was found that R134a provides the most practical replacement for R22, specifically for low-temperature situations [43] .
The Intergovernmental Panel on Climate Change has since added R-134A to its list of greenhouse gases, declaring definitively that this refrigerant is a poor choice for the future of the planet and its inhabitants.
The sales restriction is established by EPA regulations (40 CFR Part 82, Subpart F ) under Section 608 of the Clean Air Act. Only EPA-certified technicians are allowed to purchase ozone-depleting substances (ODS) or non-ozone depleting substitutes used as refrigerants, with limited exceptions.
R-1234yf refrigerant. To date, most auto manufacturers are using the hydro fluoro olefin (HFO) refrigerant R-1234yf as the replacement of choice for R134a.
