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

Emissions

Look from outer space: the Indian Ocean

Fluorinated greenhouse gases (F-gases, i.e. partially fluorinated hydrocarbons, fully fluorinated hydrocarbons, sulphur hexafluoride and nitrogen trifluoride) are used for purposes such as refrigerants, foam blowing agents in certain foam products, and insulating gas in switchgears. Some of these substances have an extremely high Global Warming Potential. read more

Climate friendly mobile air conditioning for buses

Buses are eco-friendly means of transport, nevertheless their climate performance can be increased still further. Today’s mobile air conditioning systems in buses still use the refrigerant tetrafluoroethane (R134a), a greenhouse gas with a 1,430 times higher impact to the climate than carbon dioxide. There is a climate friendly alternative: Some city buses already use CO2 air conditioning systems. read more

Commercial refrigeration units are used to keep food fresh and keep frozen products frozen, primarily in the grocery industry as well as in bars, restaurants, florists and other businesses. Some 30,000 refrigeration units were installed in German food stores in 2006, most of them direct heat exchanger units that use HFC 134a or 404A refrigerant. read more

Building air conditioning

A lot of room air conditioners hangig on the face of a building

It is only recently that air conditioning has become relatively common in German buildings. The high standard of living has ramped up expectations concerning comfort and convenience in the home and particularly at the workplace, and this in turn has increased energy demand. The refrigerants used in more than 95 percent of Germany’s air conditioners strongly affect the climate. read more

Moble air conditioning in cars, buses and railway vehicles

An EU directive has banned the use of fluorinated refrigerants with a global warming potential of more than 150 in certain mobile air conditioning systems since Jan. 2011. It requires the previously used refrigerant tetrafluoroethane (R134a) to be replaced. Natural refrigerants are considered the best environmental alternative. Climate-friendly alternatives are also available for buses and trains. read more
