A High-Performing Alternative to R-134a Opteon™ XL10 (R-1234yf) refrigerant is a non-ozone depleting (ODP) hydrofluoroolefin (HFO) option that meets the industry's growing demands for sustainable, safe, and effective solutions.
R513A was developed as a replacement refrigerant for R134a. R513A is a modern, non-flammable refrigerant designed to replace R134a in a wide range of applications. It provides a sustainable solution for both new systems and retrofits.
You cannot change an r1234yf system to be compatible with r134a. It is both illegal and damaging to the AC system components due to the different types of refrigerant oil used between the two refrigerants.
Some notable substitutes for R134a [10] in AAC based on the preceding studies are R1234yf [[11], [12], [13], [14]], R1234z (E) [[15], [16], [17]], R152a [[18], [19], [20]], R290 [21,22], R744 [[23], [24], [25]], R430A [26,27], and R444A [28], etc.
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.
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.
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.
Possible alternatives to R-134a
Attention is increasingly focused on low-GWP refrigerants that are hydrofluoroolefins (HFO). R-1234yf in particular is often seen as a possible alternative to R-134a. The GWP value of R-1234yf is 4, which means it has a very low global warming potential.
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.
The cooling capacity of R1234yf used as a drop-in replacement in a R134a refrigerant facility is about 9% lower than that presented by R134a in the test range. This difference in the values of cooling capacity obtained with both refrigerants decreases when the condensing temperature increases and when an IHX is used.
A High-Performing Alternative to R-134a
Opteon™ XL10 (R-1234yf) refrigerant is a non-ozone depleting (ODP) hydrofluoroolefin (HFO) option that meets the industry's growing demands for sustainable, safe, and effective solutions.
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.
In with the new
The new refrigerant type uses ND-oil 12, also a PAG 46 oil but with additives specifically for the R1234yf type refrigerant.

R1234yf was chosen to replace R134a in all new cars by 2021. Some manufacturers have already made the switch, or the switch is in progress. In fact, as of 2018, 70% of new Kia cars already come equipped with R1234yf!
In the United States, vehicles produced after 2021 no longer contain R-134A in the air conditioning system. In other parts of the world, including the United States, there are restrictions around using 1,1,1,2-tetrafluoroethane. Specifically, in California, retailers can deny selling customers canned R-134a.
Regulatory - There are no published regulations or granted EPA petitions that state R-32 will be prohibited in the U.S. after 2029. In fact, R-32 is a single component refrigerant, while R-454B is a blend that consists of nearly 70% R-32.
R744 (CO2) is refrigerant grade CO2, used as a replacement for R134a and R404A in ultra-low, low and medium-temperature refrigeration applications.
The test results conclude that the blend R134a/R32 at a mass fraction of 85/15 can be a drop-in replacement for R134a refrigerant.
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.
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.
RED TEK 12a is designed as a direct drop-in replacement for R-134a and R-12 substitutes.
SUB-ZERO® 345 18 oz. One of our better systems, Sub-Zero® is an excellent all-purpose R-134a recharging system for cars and trucks. EZ CHILL® MAC-134 18 oz. The perfect choice if you're on a budget, EZ-Chill® is a good all-purpose R-134a recharging system for cars and trucks.
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.
