Automotive Refrigerants-How much do you know?

With summer just around the corner, have you ever wondered where that cold air comes from when you turn on your car’s air conditioner? Well, the answer is that some of that cold air comes from the refrigerant in your car’s air conditioning system. So, which refrigerant is in your car?

If you are a car owner in this article you will learn about the three commonly used refrigerants and which one your car needs.
If you are a professional technician in a repair shop you will learn how to choose a refrigerant filler in the article.
Warm tips:
  • Automotive refrigerant is a volatile chemical requiring professional refrigerant recovery.
  • Automotive refrigerant is a refilling machine to maintain your car’s air conditioning system so that you can quickly recycle the old refrigerant and refill it with new refrigerant.
  • Environmental protection laws in many countries make it illegal to vent refrigerants.
  • This chemical has been found to destroy the ozone layer and contribute to global warming.

Four common automotive refrigerants

  • Generation I: R12 – currently banned

R12 Automotive refrigerant is a chlorofluorocarbon that contains the element chlorine, which makes it very damaging to the atmospheric ozone layer.

R12 was widely used for many years because it was effective and inexpensive. In 1994, the U.S. banned R12 in all new cars.R12 is now banned worldwide.
  • Generation II: R22 – currently being phased out.
R22 Automotive refrigerant is a second-generation refrigerant that also causes damage to the ozone layer in the atmosphere; it has a high greenhouse effect value, and this type of refrigerant is now rarely used as a refrigerant for automobiles
  • Generation III: R134a – the refrigerant your car’s air conditioning system is likely to use
With the development of the times, the demand for automobiles has increased. Policies to protect the environment around the world are also getting better and better. Almost every car produced since 1994 is equipped with R134a refrigerant, which is the refrigerant that allows air conditioning systems to blow cool air on hot summer days, and which has a high greenhouse effect value even though it doesn’t damage the ozone layer of the atmosphere.
However, by today’s standards, R134a isn’t exactly friendly to the environment either; R134a has been found to have a high greenhouse gas potential because it ends up in the atmosphere and takes a long time to break down. As a result, all new cars sold in the U.S. after 2021 will no longer be able to use this refrigerant.
  • Fourth Generation: R1234yf -Hot TopicsHot Topics
By the end of 2022, nearly 200 million volumes of vehicles using R1234y have been sold. This includes between 171 and 180 million units in the US and Europe alone. On top of that, there are additional sales in other parts of the world.
Currently, more than 100 million vehicles in Europe and more than 80 million in the United States use R134yf refrigerant. So it is now easy to upgrade your car’s air conditioning system from R134a to R1234yf compatibility. Special attention should be paid to the fact that refrigerants should not be mixed. Maybe shortly we will find out about the dangers of R1234yf as well. Be sure to bookmark this post and we’ll continue to update it with the latest information.
