Quick Answer: Why Was R12 Phased Out?

When did r12 get phased out?

1995This has happened before, one of the first gasses to be completely phased out was R12 in 1995.

After the production of R12 stopped the price rose by hundreds of dollars.

It was used in air conditioning and refrigeration.

Retrofit (replacement gasses) became available..

Is there a replacement for r12?

Replacements for R12 The best replacement for R12 is considered to be R-134a. … 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.

Is r12 still made?

Although it’s not produced any more, R-12 is still being recycled. It’s being pulled out of older cars and refrigeration units, cleaned and sold back to customers who still want or need it.

Is r410a a Class 1 refrigerant?

No. Just like R-22 the new R-410A is rated as an A1 classification by ASHRAE. A means non-toxic and 1 means non-flammable. For more information on toxicity and flammability ratings of refrigerants click here for an article I wrote the other day.

Can I replace r12 with r134a?

R134a systems operate at higher discharge-side pressures than R12, which can cause compressor seals to leak. Bottom line, R134a simply doesn’t cool as well as R12. … The advantage of ester oil is that it works with both R12 as well as R134a, so you can fill the system with it and then use either refrigerant.

Can you replace r12 with r22?

But R22 is almost equally damaging. … 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.

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.

Why are Hcfcs being phased out?

New EPA rules are phasing out hydrofluorocarbons (HFCs) due to their high global warming potential. When CFCs were banned two decades ago, the phase-out sparked concern about refrigerant cost, availability, and performance.

Yes you can legally sell the R12 you personally own. The catch is that only a licensed technician can handle the R12, meaning purge and charge a system, but that is up to the individual purchasing the R12 if they want to follow the law by finding a technician or not.

Why is CFC bad?

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.

Why are HCFCs better than CFCs?

Because they contain hydrogen, HCFCs break down more easily in the atmosphere than do CFCs. Therefore, HCFCs have less ozone depletion potential, in addition to less global-warming potential. HFCs do not contain chlorine and do not contribute to destruction of stratospheric ozone.

Can you mix 134a with r12?

You cannot mix R-12 with R-134a, they are not compatible (and neither are the compressor oils used with them).
