R 1234yf Refrigerant
Reports that the leaking of a certain type of air-conditioning fluid used in electric vehicles may help cause global warming may be a bit of hot air. The Union of Concerned Scientists (UCS) is addressing stories saying that HFC-134a, also known as R-134a, may nullify the benefits of driving electric because of its potential effect on the ozone. The UCS debunks those stories.
The case of Dupont and Honeywell's refrigerant R-1234yf is doing the exact opposite of keeping things cool. The two chemical companies have spent years and hundreds of millions of dollars developing R-1234yf to replace R-134a, the new refrigerant shown to be 99.7-percent kinder to the environment than the one it is meant to succeed. Part of that development has been years of tes
Last week, Daimler announced that it would be sticking with R-134a refrigerant in its cars due to some tests it conducted that showed the newer, more environmentally friendly R-1234yf ignited in certain crash tests. Apparently, this Jeffrey N. Ross
Just like the R-12 refrigerant that was phased out of cars in the 1990s, it appears R-134a is on its way out, as well, in favor of the more environmentally friendly R-1234yf. While R-134a definitely isn't as harmful to the ozone as R-12 was (which led it to be banned), the newer R-1234yf has a far lower global warming potential than the refrigerant currently used. This sounds good for the environment and all, but Jeffrey N. Ross
