I checked on the dupont site and it says 134 auto can be used in commercial applications.

Where did you find this on the Dupont site? I looked and was unable to find any information on CHF2-CHF2 being used in refrigeration applications. Basically the difference in the two relates to how the atoms are attached in forming the chemical compound. The same type and amounts of atoms are used. From the research I have done, it appears that R134 is used primarily as an expanding agent in foam applications.

In this type of application it appears as if R134 actually works much more efficiently then does R134a. What is not clear to me is why R134 is not used for refrigeration applications. Maybe it has to do in part with the boiling point of R134 vs. R134 did not make the “cut” as a potential replacement refrigerant. I was unable to determine exactly why.
