Richard Cronin is a researcher who has written several papers on the ozone and the claims CFC'S are causing a hole.

Richard states:

RE: refrigerants and the putative ozone hole

Mind you, as we migrate to different refrigerants, the thermodynamic properties are different so the air conditioner machinery is different. Plus, because you have different machinery running less efficiently and at higher temperatures, you require different greases, lubricants, hoses, and gasketing.

The linked article mentions the "Final Solution” in the Montreal Protocol. That is, totally Chlorine-free refrigerants. Yup, R-1234yf for cars is totally Chlorine-free. It is also a powerful greenhouse gas (yuck, yuck, chuckle).

Also, R-1234 yf is toxic and flammable so if you are in a car accident and your refrigerant reservoir ruptures you are DOOMED !!

The original refrigerant for automobile air conditioners was R-12. The reduced chlorine substitute ( fluorine replacing chlorine) is R-134a. Globally, R-12 is still the most broadly used refrigerant in auto A/C. You can still buy R-12 over e-Bay or Amazon for older model cars.

Wait !! There’s more !!

The original refrigerant used in home air conditioners was R-22. The first reduced chlorine substitute was R410a. In the U.S., home air conditioners run about half as R-22, half as R410a. Again, you can buy R-22 on e-Bay or Amazon.

The spanking new chlorine-free substitute for home air conditioners is R-32. You’ll have to replace everybody’s home air conditioner and R-32 is flammable.

But that’s all we know for now.

I won’t talk about Chloro-fluoro gases (CFCs) used for plastic blow molding ( i.e. bubble wrap).
