HFO 1234yf Refrigerant Replacing R134a

HFO 1234yf Refrigerant Replacing R134a

For decades people have wondered what would be next in the world of automotive air conditioning. Just like with other fields, both in the automotive sector and outside of it, there are changes that continue to take place. There are also good reasons for the changes that are being considered and recommended.


Decades ago we started out with the R12 refrigerant, assuming that all was well. We then found out that the CFCs were depleting the ozone. We need our ozone layer to protect us from the sun’s harmful rays, so we had to take action. We replaced the R12 refrigerant with R134a. This happened in 1995, and was supposed to make everything better. And for years we thought it did!


While we believed that R134a was safe for the environment, we have now learned that it could be adding to climate change. Some believe that it may be a super greenhouse gas, thus leading to some environmental problems we were trying to leave behind. So now there is something new that is being used and it is called HFO-1234yf. Created by DuPont, HFO-1234yf is a refrigerant that is supposed to be the answer to our vehicle air conditioning problems in regard to the environment.


HFO-1234yf supports new environmental regulations to help reduce climate change and is supposed to be much easier on the planet. In fact, it is estimated that using HFO-1234yf will provide an estimated 99.7 percent reduction in global warming contribution in comparison.


Now you know a bit more about HFO-1234yf, that it may replace R134, and why that is so. Some people contend that there are still issues with HFO-1234yf that need to be addressed, however, including the fact that it is flammable. As mentioned before, refrigerant producers are working to try and create a safer product that will help keep us cool. It’s just a matter of time before it’s all worked out and we are happily keeping cool, knowing we are doing better for the planet, too!
