R-134a Advantages
Hi,
I would like to know the advantages involved by using R-134a.
I've seen a big drop in BTU output, if compared to R-22 or R404a.
Other than the refrigerant has no blend, what are the other reasons to use R-134a?
Regards.

Re: R-134a Advantages
Honestly? I can't think of any, it seems to be a rather limp gas, but seems good for high temp hermetic chillers thats about it.

Re: R-134a Advantages
What MG pony's says and I like his wording "limp" when it comes to replacing good old R-12. I'll add that it works pretty good for MHT coolers and for autos here in the states. Both my cars have it and it works good here in Nevada, you know 115F, it's a dry heat.

Laughing hard at these two comments
R134a is not a fave of mine thats for sure, theres a trend over here putting it in place of MT and HT R507 and R404a systems (copying europe) due to the GWP, lets fork out more on capital equipment costs then more again to keep the thing running energy wise...and she said "give it to me you big fridgie"

Re: R-134a Advantages
Its still toxic if it burns, it will burn happily if hot enough. So still no real advantage, plenty of immagined ones but verry little real ones.

Re: R-134a Advantages
Seems like all engineers have their opinions over R134A.Its got its positives and negatives,I guess.Seeing that its regarded as a medium temp gas,i still prefer R404A,seeing it can be used in medium and low temp applications,and it contains a percentage of R134A.Just a thought...

Re: R-134a Advantages
r134-a is mostly used for refrigeration purposes and is not ideally for air cons R22 AND R404a are mostly uses for them cause they are mainly ****tail gasses which R134 a is not so much
