What is the best replacement for R12 refrigerant?

What is the best replacement for R12 refrigerant?

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 you still use R12 refrigerant?

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.

Is R12 better than R134a?

R134a is a safer replacement for R12. Another major difference is the type of oil both refrigerators require. R12 is compatible with mineral oil, and most R12 systems use this. R134a uses Polyalkylene Glycol (PAG) oil.

Is R12 banned?

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.

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 r502 refrigerant used for?

Developed for use in low temperature refrigeration (the evaporator pressure stays out of vacuum down to -40°F). R-502 offers lower discharge temperature and improved capacity compared to R-22.

Can I use R-22 instead of R-12?

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. R12 and R22 are both now banned by the EPA in the United States.

How bad is R12 for the environment?

R12 has a GWP rating of 8500 and takes 150 years to break down. Another refrigerant, R744, contains carbon dioxide and is expected to gain ground in this market in high-end luxury cars.

Does Supertech R134a have oil in it?

Yes there is oil in the system to keep the compressor lubricated. It is carried throughout the system in the refrigerant. It is usually added in when the system is charged.

Why was R12 discontinued?

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.

What oil does R12 use?

Mineral oil
Mineral oil is used in the old R12 systems. It has worked well for a long time and is recommended for all R12 applications. R12 takes mineral with it as it travels through the system, meaning it has a high affinity for mineral oil. Mineral oil is not mixed with R134a.
