New a/c refrigerant

In reading through one of the technical manuals I see where the industry is introducing R-1234yf which will be rated mildly flammable. Guess I'll need to stick a couple jugs of R-134a in the back of the shop. Has anyone worked with this new refrigerant yet?

I thought 744 (co2) was going to be the next auto/home refrigerant...

Now we are getting our technical information from FACEBOOK ????
There is something basically wrong with that....
Can't we find that information on some Government Website written where no one can actually tell what they are saying or meaning ?

Great , Honeywell and Dupont own most of the patents.... and no where is oil miscibility given....

How ironic can you get !!
The greenie hippies will love this !! Using the stuff they say causes global warming to negate its effects !!

Its as though technology has overtaken itself.
We started with R12 & it became a no no because it stuffed the atmosphere, now the stuff that they say is stuffing the atmosphere is going to be the next big thing to negate its effects.

"Second, PAG oil is not compatible with this refrigerant in any amount and could cause reliability and safety issues."

"Another hot topic was "Should the DIYers have access to HFO1234yf?" This question was also answered with a resounding "No!" In fact, the SAE and some environmental groups are pushing to restrict the sale of R134a (R12 is already restricted) to certified technicians only, removing the little DIY cans from many retail outlets. "

Well, as long as the ' restriction ' involves an open book test over the internet and about $20 cash... that is ok with me... it just helps make sure those purchasing it know what they are supposed to do and why... It is not usually too much of a problem to follow the rules.

So flamable refrigerant in a car is ok so long as it saves the environment now? Propane to replace R12 still not ok? Figures

I guess retrofits will be out of the question!!

It would make a nice load bang when the condenser let go !!
1800 psi at the front of a car !!! I dont think so !!
