We like to provide a good climate on our trains. We are currently testing new air conditioning systems in our trains, which cool and heat the air using natural refrigerants. These take the place of conventional synthetic refrigerants and protect the environment.
Testing prototypes
Three of our industrial partners are also involved in our tests, which are taking place on services operated by rail companies DB Regio, Südostbayernbahn and Mainfrankenbahn.
The new refrigerants not only provide fresh air. They also reduce energy consumption and the use of synthetic refrigerants. The refrigerants used in the new systems are more environmentally friendly than traditional coolants. Another advantage of the new air conditioning systems is that they not only cool the air in the summer, but they also provide heating in the winter thanks to an integral heat pump.
As a matter of interest, we have had eco-friendly air conditioning systems in our ICE 3 trains for around 20 years now. This has contributed toward reducing our energy footprint and protecting the environment.
