PartagerCO2 air-conditioning systems in German buses
During the 12th Karlsruher Fahrzeugklima Symposium in September 2011, new approaches in mobile air-conditioning systems in buses were presented and an overview of a number of CO2 MAC buses in Germany was given.
During the 12th Karlsruher Fahrzeugklima Symposium in September 2011, new approaches in mobile air-conditioning systems (MAC) in buses were presented and an overview of a number of CO2 MAC buses in Germany was given.
Out of a total of 26 buses equipped with CO2 mobile air-conditioning systems (MAC) in Germany, 22 buses are still in operation today. The currently oldest bus belongs to Saar-Pfalz-Bus and has been using a CO2 MAC system since 2004. The good experiences have encouraged the regional transport company to acquire in total 5 buses with CO2 MAC in 2011, while the public transport company of Berlin (BVG) integrated 7 buses with CO2 MAC into their fleet in 2010.
In 2010, the regional transport company of Kurhessen (RKH) introduced in Kassel for the first time a bus equipped with a reversible CO2 MAC, which not only cools but also heats the bus. The average COP of the system, calculated from the ratio of cooling/heating performance to motor output, was 3.54 (3.1 in A/C mode, 3.8 in heat-pump mode).
