Yes, R-12 is a chlorofluorocarbon (CFC) refrigerant that was commonly used in air conditioning systems and refrigeration units. However, due to its harmful effects on the ozone layer, its production and use have been severely restricted under the Montreal Protocol.

How does r12 damage the ozone?
R12, or chlorofluorocarbon-12, reacts with ozone in the stratosphere, breaking down the ozone molecules. This leads to a reduction in the ozone layer, which is important for shielding the Earth from harmful UV radiation. As a result, increased levels of R12 can contribute to ozone depletion.
What is chemical name of cfc?
CFC is an abbreviation for the class of chemical compounds known as Chloro-Fluoro-Carbons.
How do the humans effects the ozone?
Humans produce CFC's. These CFC's react with ozone to deplete it.
Why is hydrochloroflorocarbons dangerous?
CFC's are dangerous. These CFC's result in mass depletion of ozone layer.
What class of molecules has CFCs replace?
CFC's are ozone depleting substances. HCFC's are an alternative to CFC's.

What element in R12 was harming the ozone layer?
R-12 is a CFC. It releases chlorine and fluorine.
Why was Freon banned in the US?
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.
What is the risk of mixing freon r12 with freon r134?
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
What is CFC in HVAC?
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.
Which gas is used in fridge insteadof cfc?
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.
Is air-conditioning gas toxic?
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?

What is the fluid in car air conditioning called?
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.
What type of freon should be used in older model ac units?
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.
How do you know if r12 freon is in vehicle?
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.
What type of freon can you use in a dodge dynasty?
It was built with R12, can be coverted to R134aIt was built with R12, can be coverted to R134a
