R-12 is a colorless and odorless CFC refrigerant that was completely banned from production by 1996 under the Montreal Protocol for depleting the ozone. R-12 has many applications in refrigeration and air conditioning including large to mediums size chillers, automotive air conditioning, and as an aerosol propellant.

When did they stop using R12 in refrigerators?
In 1994, governments banned the use of R-12 in new refrigerators and air-conditioning systems due to its damage to the ozone layer. Since 1990, the less harmful replacement for R-12, R-134a, has been used in many old systems.
What year did they switch from R12 to r134a?
R12 and 134a are refrigerants used in car air conditioning systems. R12 was used in most cars and trucks until 1995 when it was replaced with 134a.
Why is R12 banned?
In conclusion folks R-12 Freon was banned due to the damage that it caused to the Ozone layer. The Chlorine found in CFC refrigerants like R-12 would not break down in the atmosphere when vented or leaked. The Chlorine would then erode the Ozone bit by bit.
Is R12 still legal?
Is it legal for me to sell? Yes, you can still sell R-12 and other CFC refrigerants. Although these refrigerants can no longer be manufactured, it is perfectly legal to sell to an EPA certified buyer.
What can I use instead of R12?
There are three replacement refrigerant options for R12 systems: R134a, R401a, R401b. R134a is regarded, by manufacturers and adherents to the Montreal Protocols alike, as the best replacement refrigerant.
What happens if you put R134a in a R12 system?
R134a systems work at higher discharge-side pressures than R12 systems, which could lead to compressor seals leaks. Additionally, since R134a is composed of much smaller molecules, it has a greater chance of leaking from an R12 system.
What year did they stop putting Freon in cars?
For many years, R12 was the automotive refrigerant standard. It was effective and cheap. However, scientists quickly discovered its sinister secret: It was partially responsible for the rapidly-depleting ozone layer. In 1994, it was banned from all new cars sold in the US.
Is R12 better than r134?
R12 can blow 6 to 7 degrees cooler than R134a and is 15% more efficient. ... As a result, a perfectly functioning R12 system will blow colder and reduce temperatures faster than a system that was converted to R134a.
What year did they change refrigerant in cars?
Many collector car owners wonder what to do about their air conditioning (A/C) systems as ever-changing government regulations dictate the type of refrigerants allowed. In 1994, Freon, or R-12, was outlawed and replaced by R-134a and that is now being replaced.
Who invented R12?
DuPont led the industry in the invention of safer fluorocarbon refrigerants with the introduction of FREON 12 in 1931.
What is cci2f2?
also known as Freon 12. Chemical Abstracts Service (CAS) Number: 75-71-8. General Information. Dichlorodifluoromethane is a colorless, non-flammable gas that can affect you when breathed in.
What is CFCL3?
Trichlorofluoromethane is a colorless, odorless gas at normal temperatures and pressures. ... The chemical formula for Trichlorofluoromethane is CFCL3.
Can I buy R22 in Mexico?
Mexican manufacturers of HVAC and cooling systems have stopped making units based on R22 or R141b for its high CFC content; Mexico is replacing, retrofitting or discontinuing all R-12, R-22, R502, R401A, R402, R406 and R408 based units.
Can I use R12a in a R134a system?
It's illegal to vent R134a into the atmostphere! You don't just blow it out! Just adding R12a to a 134a system doesn't work very well because a 50/50 mix is very inefficient. If you don't have a vacuum pump, you can still make it work though.
When was R22 phased out?
R-22 is a refrigerant that is often used in air- conditioning equipment. Because R-22 depletes the ozone layer, production and import was further limited in 2010. In 2020, R-22 will no longer be produced or imported. After 2020, only recovered, recycled, or reclaimed supplies of R-22 will be available.
