Ferrari Mailing List: Re: Partial FC: Commercial A/C refrigerant

[Rick Moseley (ramosel]

Actually there is such a thing as commercial refrigerant...  many of them.  I don't know that you'd be able to run any in a car but commercial applications I know of besides R134a.

R744

R290

HFO

R410A

R404A

R407A

R11

R22

R114

and of course the ammonia derivatives.

I was a data center IT guy so keeping crap cool was a big thing.   Not sure which of these get used where or how, but they are out there.  Some of our centrifugal compressors had 6ft diameter impellers and ran on direct 4160volt feeds from the power company.  I think that would be considered commercial.

IMO your car guy does not know what he's talking about.  There is no such thing as "commercial" refrigerant so he's probably referring to R134a.  Here's a good read on converting from R12 to R134a - http://www.griffiths.com/achelp/achelp3.html

Erik's analogy of the 512BB air conditioning reminded me of something...

 

A car guy told me recently he uses commercial A/C refrigerant in his truck and the cold air it produces is insane. I asked him which one he uses and hasn't gotten back to me.

 

Is this something anyone would consider on the older cars? It's better than using R12.

 

Nobody should have to suffer from subpar A/C in a 30 year old car, and that statement alone should stand up in the court of law.
