Can R12 still be used?

It became known as R12 or Freon. When used in refrigerator and A/C systems, R12 cooled incredibly well. And it was safe—neither poisonous to breathe, nor flammable. International manufacturing of new R12 ceased in 1996, but existing R12 can still be reclaimed and purified.

Why is R12 illegal?

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.

When did R12 become illegal?

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.

What is the best replacement for R12 refrigerant?

R134a
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.

Can R22 replace R12?

R12 and R22 are both now banned by the EPA in the United States. Other more environmentally friendly alternatives exist, but even those cannot be changed in air conditioners or other refrigeration units with R12 without a thorough cleaning of the unit.

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.

Is R12 banned in Australia?

It is illegal in Australia to recover R12 for reuse. The vast majority of technicians do the right thing and reclaim R12 for safe destruction but a few cowboys might recover and keep it for reuse.

Is R12 bad for environment?

R134a has since been classified as a ‘high global warming potential’ gas. The chlorofluorocarbon-based R12 it replaced would be even more harmful if it had remained available. R12 has a GWP rating of 8500 and takes 150 years to break down.

Is R12 colder than R134a?

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.

Is Freon 12 the same as R12?

Refrigerant R12 or Freon 12 is said to be the most widely used of all the refrigerants being used for different applications. The chemical name of refrigerant R12 is dichlorodifluoromethane and its chemical formula is CCl2F2. The wide range of applications of the refrigerant are due to its safe properties.

What is R12 compatible?

Replacements for R12 R-134a is nonflammable and non-explosive and has good chemical stability though it has some affinity towards moisture. The other two refrigerants that are considered good replacements for R12 are R-401a and R-401b. R-401A is the mixture by weight of 53\% of R-22, 13\% R-152a and 34\% R-124.

Can R22 be used in cars?

R22 refrigerant has been used for years in central air conditioners, heat pumps, mini-splits, car AC systems, and other refrigeration equipment. It’s the key to absorbing and removing heat from a space.
