R-12 is a CFC. It converts into chlorine and fluorine to deplete ozone.
there are many types of freon. cfc's fcfc's etc.
No, CFC's are not stable. They react with ozone.
The Alternatives for CFC's are there in the market. These are called HCFC's.
CFC's are used in refrigerators. One of a CFC is R-12.

R-12 is a CFC. It releases chlorine and fluorine.
Freon wasn't banned - Freon is a name trademarked by DuPont for a line of CFC and HFC refrigerants they manufactured. What was banned were CFC refrigerants (such as R12). They were banned from further production due to the negative environmental effects they have.

Chemical instability of mixing a CFC and HFC together increases the risk of fireExcessive system pressure resulting in damage to or destruction of AC system componentsImproper lubrication of the compressor since the R134a won't carry the oil used for R12 systems properly
CFC is Cloroflurocarbon and it refers to the Clourine, Flourine, and Carbon that are present in Freons such as R12. Most home AC units use R22, which is a HCFC, that is HyrdoClouroFlouroCarbon. Any Freon that starts with R requires a EPA license to purchase, and any that ends in A (such as 410A or 134A) is available to the public.
Depends on which type of refrigerator. Some industrial units still use pure ammonia. The CFC refrigerators typically used R12, just like car air conditioners, and likewise switched to R-134a (HFC 134a) when the further production of R-12 was banned.
Depends on what type of AC system it is. Some AC systems use water, which, of course isn't. The ones which use HFC and CFC refrigerants (R12, R134a, R212, R22, etc.) are, however.
how to convert r12 to134r
It's actually a gas, and it's known as refrigerant - depending on model year, it may be CFC-12 (R12) or HFC-134 (R134A). A lot of people call it Freon, but it's sort of a misnomer.. Freon is a trademark name by Dupont for a line of CFC and HFC refrigerants they manufactured, so it's not actually Freon unless Dupont made it and marketed it under that name.
Define "older model". Up to the early 90s, they used R-12/CFC-12. Good luck trying to get that anymore. R414B is the recommended replacement for R12 systems.
If if it a 1995 or older then it came with R12 installed. 1996 can be R12 or R134. 1997 up, it has R134/R134a. If you suspect it had R12 look for a label somewhere on the A/C unit signifying it has been converted. If you find it has R12 and is leaking and needs repairing, after the leak is repaired, convert it to R134a. R12 is far too expensive to use.
