R134a does not degrade ozone. At all.I read an article once, that mentioned the old R12 Freon uses 1800x the ozone, and R134a uses 600x.
So an ounce of released R12 uses 1800 ounces of ozone to react with.
Thanks for setting me straight. I corrected my earlier statement.R134a does not degrade ozone. At all.
OTOH, R134a has been assigned a global-warming-potential (GWP) rating.
Methane (cow farts) has also been assigned a GWP rating. And, in fact, the GWP rating for R134a is about 20 times higher than the GWP for methane. So let's say a Cobalt is involved in an accident which ruptures an a/c hose and that 3 pounds of R134a is released into the atmosphere. Would this be the equivalent of 60 pounds of cow farts being released into the atmosphere? Inquiring minds would like to know.
You da man, Ross. And yup, the ozone hole won't be getting any bigger as a result of R134a.Thanks for setting me straight. I corrected my earlier statement.
That sounds just about like the R134a being fazed out and the new R1234YF being introduced. And the same kind of 1 manufacturer. I can not remember if it is DuPont or not.I am a licensed HVAC contractor for commercial and Residential systems and maybe i can shed some light on coolants. Currently I work with R-22 coolant (the old) and R-410A (the new) coolants in A/C systems. Everyone in my industry talks about Dupont used to own the patent on R-22 and when the patent ran out was the same time the government said it was bad on the atmosphere and could no longer be produced. Well Dupont already had their new product R-410A conveniently ready to go and is now the industry standard.
Other companies filed a lawsuit and Dupont could not patent R-410A so the same refrigerant goes under different names with different manufactures.
Im saying all of this because personally I dont think that the atmosphere has been affected by refrigerants and I feel that studies are greatly influenced by big money corporations gaining an upper edge in the market.
I have heard the same story from another. Money. Lobbyists. Politics. Keeping competitors out of the marketplace and profits up.........I am a licensed HVAC contractor for commercial and Residential systems and maybe i can shed some light on coolants.
