Another challenge is that many individual states are already adopting or proposing their own regulations to phase down high-GWP refrigerants. “Eight states have adopted the old vacated EPA SNAP [Significant New Alternatives Policy] Rule 21 to phase out R-134a and R-410A for use in chillers, and 10 other states are in the process of adopting the regulation with an effective date of Jan. 1
1,1,1,2-Tetrafluoroethane (also known as norflurane , R-134a, Klea 134a, Freon 134a, Forane 134a, Genetron 134a, Green Gas, Florasol 134a, Suva 134a, HFA-134a, or HFC-134a) is a hydrofluorocarbon (HFC) and haloalkane refrigerant with thermodynamic properties similar to R-12 (dichlorodifluoromethane) but with insignificant ozone depletion

Refrigerant (R-134a) Freonâ„¢ 134a (R-134a) in Chillers Product Information Introduction Because of the phaseout of chlorofluorocarbon (CFC) refrigerants, environmentally acceptable replacements have been commercialized for use in new chillers and in chillers originally designed for use with CFCs. The
North America and Europe with HFO -1234yf, converting them to R -134a • Daimler stated that it would continue to use R- 134a • The German Automobile Manufacturers Association (VDA) restarted development activity for R -744 systems • The industry quickly initiated another safety evaluation of HFO -1234yf in response to the Daimler claims Genetron® 134a (HFC-134a) has been developed by Honeywell to serve as one of the key substitutes for CFCs and HCFCs. Genetron® 134a is a long-term, environmentally safer, non-ozone depleting substitute. As a refrigerant, it possesses similar energy efficiency and capacity characteristics as R-12 and has an intrinsically low toxicity.
They can have impacts on the climate hundreds to thousands of times greater than the same amount of carbon dioxide (CO 2). The impact is measured by the global warming potential (GWP) of a substance; one kilogram of a greenhouse gas with a GWP of 700 has an impact on the climate that is 700 times stronger than one kilogram of CO 2 , which has a
So On an R134a car, the high side service port is larger. a 16mm fitting, and the low side service port is a 13mm fitting. Now the low side R12 retro adaptors will always be 7/16-20 to 13mm (1/4) and the high side can be 7/16-20 to 16 (1/4)or 3/8-20 to 13mm (3/16) The hose that hooks up to the R134a guage set is 1/2in acme male or 1/2 acme HFCs are a class of chemicals used as refrigerants, in fire suppression systems, and in certain scientific equipment. HFCs are greenhouse gases (GHGs) with global warming potentials (GWPs) hundreds to thousands of times higher than carbon dioxide. The United States (U.S.) Environmental Protection Agency (EPA) is implementing the HFC phasedown Green Gas, Top Gas, and propane are all pretty much the same thing and will give you about the same fps. HFC134a (or you can use duster gas) is a much weaker gas, which might not even work in your
R-134a and 1234yf systems are very similar to each other. In fact this was one of the reasons that 1234yf was chosen as an alternative refrigerant. A few of the major differences can be read below: Slight design differences in the design specs of certain components like TXVs, ports, evaporators, and condensers. Service ports are different then

This product is a hydrofluoro-olefin (HFO) refrigerant. It is made up of the same types of atoms as HFC refrigerant, but the atoms have at least one double bond, making its properties unique from freon R-134a. Environmental standards. For practical application, the main difference between these two types of freons is their environmental impact.

R-134a Refrigerant PT Chart. R-134a is the most common refrigerant found in automobiles today. It has been in use since the early 1990’s and now, in 2019, we are beginning to see it’s popularity wane with the rise of the new HFO refrigerant known as R-1234yf. That being said, there are still millions of cars on the road that use R-134a and
