Hi,
You raised a very important point.  Freon is not a name of a specific material (gas) but to a family of materials.  Freon is another name of Hydro-Fluoro-Chloro-Carbons.....  In simple words: It is an organic chain that has in it, in specific places, radicals of: Fluor (F), Chlore (Cl) and Hydrogen (H).  That family (or "goup" of materials) are different types of specific materials (chemical composition, 1-1-3 Freon etc.):  R-12 (known as "the Old Freon") was in frequent use in cars airconditioning systems was greatly replaced by the R-134a (known as "the new Freon") or by the R-22 (HCFC).  And there is a list of other types of Freon as well (R406a [autofrost], R142b, etc).  Some of them are believed to attack the "Ozone" and were banned and some are more friendly.  If you need more information / explanations contact me. 
Best regards,

Love is the battery of life....

Thanks for that info. What I'm really wanting to know is what is the difference chemically and can for instance R22 be substituted for R134a in a refrigerator? I've converted quite a few cars/trucks from R12 to R134a. I know you can't mix different freons, I really just don't know why you can't substitute certain ones for others. For instance, Ihave a small refrigerator that uses R134a. It got a leak and I repaired it. I have a 30lb bottle of R22 which is what a lot of refers use and I am wondering if I can use the R22 instead of the R134a which is usually used in the automotive industry. It took me a long time to say that didn't it. Thanks, Steve

Hi,

A refrigerant cannot just be replaced by others because of their heat carrying capacities, which would result in undesirable cooling of the system.

Also note that each refrigerant has different co-efficient of expansion. What this does is, if a compressor is fed with a refrigerant it is not designed for, the compressor just blow off!!!!!!!

In theory you can't simply use R-134a as a drop in replacement for R-12...but I've known of people doing it. One lady I know of bought a 1979 Buick that was in good shape, but the A/C didn't work. She put in some R-134a, and it worked. In fact it worked fine the entire 5 years she owned the car.  That's not the official by the book way to do things, and that was her experience, others may vary.
