Is R12 still being made?
R12 Refrigerant Today
It is illegal to manufacture new R12, but it is not illegal to sell or use R12. And many of the cylinders and cans of Freon R-12 sold for decades throughout the United States are still around.
What is Freon R12 used for?
Dichlorodifluoromethane (R-12) is a colorless gas usually sold under the brand name Freon-12, and a chlorofluorocarbon halomethane (CFC) used as a refrigerant and aerosol spray propellant.
What does the R in R12 mean?
“R12: Extremely flammable”, a risk phrase, see List of R-phrases In transportation.
Why is R12 being phased out?
Unfortunately, R12 has also been found to cause accelerated Ozone layer depletion. Therefore, 191 countries came together at the Montreal conference in 1985 and signed something called the Montreal Protocol, which called for the complete phase out of Ozone depleting materials. This includes R12.
Can I sell R12 refrigerant?
Where Can I Sell R12 Refrigerant? A very frequent question people ask us is whether it is legal to sell R12 refrigerant. The answer is yes – but not to just anybody. It is only possible to sell Freon, R-12 or any other CFC to EPA-certified technicians, like the experts at Refrigerant Finders.
Is R12 better than R134a?
Understand that R12 has its advantages. R12 can blow 6 to 7 degrees cooler than R134a and is 15% more efficient. R134a systems require larger condensers and higher operating pressures than R12 systems because R134a doesn’t have as high of a heat transfer rate as R12 (which has a heavier molecular size than R134a).
When did R12 stop being used?
By international agreement in 1987 (the Montreal Protocol), the use and production of CFCs such as R12 began to be phased out, with automobile manufacturers required to stop using it by the end of the 1994 model year.
Is R12 toxic?
INHALATION: R-12 is low in acute toxicity in animals even at concentrations of 5% (50,000 ppm). However, when oxygen levels in air are reduced to 12-14% by displacement, symptoms of asphyxiation, loss of coordination, increased pulse rate and deeper respiration will occur. At high levels, cardiac arrhythmia may occur.
Can I put r134 in a R12 system?
To be able to use R134a in an R12 system, the R12 system needs to undergo a retrofitting so that it’s able to handle and process R134a refrigerant. This also means that some refrigerant conversion needs to be done in order to drop R134a into a R12 system.
What happens if you put 134a in an 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 happens if I put 134a in R12?
Is R12 Freon flammable?
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.
Is R12 better than R22?
Both atmospheric pressure and discharge temperature are higher compared to R12, but the power requirement is comparatively the same. Evaporator temperatures are between -28 to -40°C. The ability of r22 to absorb moisture is comparatively greater than r12, therefore, less trouble due to ice formation.
What happens if you mix R12 with 134a?
Does R12 cool better than R134a?
Can R12 and r134 be mixed?
Mixing R12 and R-134a refrigerants is illegal, and even if you previously bleed out the R12, the system has to be adjusted to use R-134a, or it will cause leaks, copper corrosion, and lack the lubrication required for optimal operation.
Can you top off R12 with R134a?
Can You Legally Use R134a in an R12 System? Ultimately, no. If you’re trying to “top off” an R12 system with R134a refrigerant, you can face some hefty fines with the Federal US government and EPA.
Can I put R12 in a R22 system?
They are two completely different refrigerants,won’t mix at all. But when it blows your system have the decency to tell the service tech what ya did. I have a R12 in basement for long time. I just use it few time for my old car (but the car was gone for ten years) so I think it has a lot left.
What is the best replacement for R12 refrigerant?
The best replacement for R12 is considered to be R-134a. The chemical name of R134a is tetrafluoroethane and it chemical formula is CF3CH2F. It is a hydrofluorocarbon (HFC) and has zero ozone depletion causing potential and very low greenhouse effect.
What happens if you put R12 in a R134a system?
As previously stated, R12 systems usually use mineral oil, which is incompatible with R134a. When R134a comes into contact with mineral oil, it can hinder the oil from returning to the compressor, or possibly reduce heat transfer.
What happens if I put r134 in an R12 system?
Which compressor uses R12?
It can be used will all types of compressors like reciprocating, centrifugal and rotary. 4) Miscibility with oil: Refrigerant R12 is miscible with the compressor oil under all the operating conditions. There are two advantages of this property of R12.
Is R22 better than R12?
R12 and R22 are two refrigerating agents for air conditioning units. R12 was once used in many air conditioning units as a refrigerant or cooling agent. However, it was found to be a very bad gas for the environment. But R22 is almost equally damaging.
Can you put 134a in a R12 system?
