Mobile air conditioning with fluorinated refrigerants

The photo shows that the fluorinated refrigerant 1234yf burned during the laboratory test.

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

Statutes and regulations

paragraphs

Fluorinated greenhouse gases and CFC are governed by international environmental treaties (Kyoto Protocol, Montreal Protocol) whose internationally, legally binding guidelines are implemented by European regulations and directives. Further legislation is enacted to achieve EU environmental protection goals. The body of European guidelines is complemented by national laws and regulations. read more

Substances such as chlorofluorocarbons (CFC) which deplete the ozone layer have long been subject to an international phase-down on their production and use. In 2016 the international community took its first steps to phase down another group of substances that are particularly damaging to the climate – hydrofluorocarbons (HFC). read more

Mobile air conditioning with climate-friendly refrigerant CO2

Silver VW Touran in front of the UBA headquarters.

An EU directive has banned the use of fluorinated greenhouse gases with global warming potential exceeding 150 in mobile air conditioning systems since January 2011. CO2 used as a refrigerant is an alternative. An UBA official car had used a CO2 mobile air conditioning system from 2009 to 2017. Since October 2016, first cars with CO2 air conditioning systems have been offered. read more

Eco-friendly transport refrigeration

Transport of refrigerated and chilled products like food is on the rise worldwide. Whether goods are transported on the road, by train or ship, the cooling temperatures must be maintained exactly. Many transport refrigeration units contain fluorinated refrigerants acting as greenhouse gases in the atmosphere. These substances need to be replaced by refrigerants having less impact on the climate. read more
