GWP is not the only point to evaluate. <BR/><BR/>The latest attempts by Honeywell and DuPont to keep the car air conditioning market is called 1234-yf.<BR/><BR/>Maybe what the DuPont man forgot to tell you is that this chemical is flammable and when it burns it decomposes into highly toxic gases, thereby putting in risk passengers and rescue personnel in case of an accident. The product's material safety data sheet classifies it as ¨extremely flammable gas¨. <BR/><BR/>He also forgot to mention that long-term effects of this new refrigerant on the atmosphere are unknown, although there is already evidence of impact on biodiversity. And also that the price will likely be much higher than the current refrigerant, thus creating an incentive for the long-term use of R134a in developing countries. <BR/><BR/>About CO2, he probably did not remember that there are several solutions available in the market today to avoid high concentrations in the passenger cabin, and that it is classified by international standards as the highest class in terms of safety. Besides the fact that it is a natural, well known substance, that several tests show it can lead to better efficiency than current systems.<BR/><BR/>Having a natural alternative which works, is it worth taking so many risks? <BR/><BR/>More importantly, first was the ozone-layer, now global warming. are we going to wait and see what is next?Anonymousnoreply@blogger.com
