Mobile air conditioning with fluorinated refrigerants
An EU directive bans the use of fluorinated greenhouse gases with global warming potential exceeding 150 for mobile air conditioning systems in motor vehicles since January 2011. Thus the current refrigerant tetrafluoroethane (R134a) has to be replaced. Tests in laboratory and car showed that the new refrigerant 1234yf selected by car industry can lead to fires. read more
Federal Environment Agency favours carbon dioxide in air conditioning systems
After findings of the latest technical tests the Federal Environment Agency (UBA) now recommends the use of carbon dioxide in mobile air conditioning systems. The refrigerant tetrafluoropropene, or HFO-1234yf, favoured by the automobile industry may well comply with the new EU guidelines, but it has greater global warming potential than the refrigerant CO2. read more
