What happens if R12 and R134a mix?

What happens if R12 and R134a mix?

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.

How do I know what kind of freon my air conditioner uses?

To know which type of refrigerant your air conditioner uses, take a look at the label on the compressor unit outside. It’ll clearly tell you which type of refrigerant the unit uses. The newer type is R-410A, and the older type that I’ve been talking about is R-22, also identified as HCFC-22.

How do I change my car from R12 to R134a?

How to Convert an R12 to the R134a System

1. Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional.
2. Open the engine compartment of your vehicle.
3. Push the high side retrofit R134a fitting over the old fitting and use a wrench to tighten it.

What is the ratio of R12 to R134a?

A charge level between 75% and 85% is recommended when converting from R12 to R134a refrigerant.

Can I put 134a in a R12 system?

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.

Why is R12 illegal?

Conclusion. 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 R 12 dangerous?

Dichlorodifluoromethane (alias of R 12 (refrigerant)) A) Freons are very toxic when inhaled in high concentrations and/or for extended periods. At lower concentrations or brief exposure, freons may cause transient eye, nose, and throat irritation.

What oil does R12 use?

Mineral oil

Is R-12 refrigerant 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. R-12 has many applications in refrigeration and air conditioning including large to mediums size chillers, automotive air conditioning, and as an aerosol propellant.
