R-134a Advantages

[jwasir]

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.

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.

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.

it's a dry heat.

A dry heat? Sounds like my relatives in Arizona. 115F and they say "But it's a dry heat"
I think the sun has melted their brains.

Both running pressures/temps are fairly low comparing to other gases.

If you want that put in R-290! It'll kick the living $h*t out of R-134a!

Thanks ALL for the nice comments

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

R134 a, Advantages, non flammable,non toxic HFC Not Cfc. Low boiling point Low cost.
Thats about it.

Disadvantages non miscible / Hygroscopic
Gwp 1300, Molecular Structure,

Thats all i can think of,

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.

It works ok for the high temp stuff like A/C or high temp chillers but other then that not much ells, even then an HC would make a far superior replacement

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...

for patent reasons ONLY, R507 is the same thing as R404a minus that teency weency bit of R134a

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

I tend to disagree . I service alot of Carrier screw chillers with R134a as the juice .
