BVG is Germany’s largest local transport company. In 2010, the company installed CO2 air-conditioning in seven buses in Berlin. The A/C systems were provided by Konvekta. Most new city buses and all long-distance buses in Germany are equipped with A/C systems with an average HFC leakage of 13-14% a year, or a total of 140,000 tonnes of CO2 equivalent.
ClimateWell systems run using heat, water and glycol, and do not require a refrigerant. The systems are particularly well suited for transit vehicles, recreational vehicles and contruction vehicles as air-conditioning can be used while the engine is off.

Deutsche Bahn, a German railway company and Europe’s largest railway operator, aims to use natural refrigerants for air conditioning in new trains by 2020. The first DB Bahn train to be fitted with CO2 air conditioning was a Siemens VT642 train, in Chemnitz (Saxony) in 2016. Since then the company has carried out a few more projects with a CO2 air-cycle system.

Konvekta has had some success outside of Deutsche Bahn with CO2 MAC in buses in Germany and Austria. “The vehicles with CO2 in operation are roughly 100 vehicles,” Michael Sonnekalb of Konvekta.
This heat pump is designed to offer air-conditioning for electric buses. Unlike other systems it doesn’t require an additional diesel heater to supply hot air.The company claims that the adaptability of the system enables optimum operating conditions for the battery, allowing an increase in range by up to 40%.
OKA, the Australian manufacturer of on/off road vehicles is the first OEM in the world to use hydrocarbon refrigerant in their mobile air-conditioning systems. The company states that by adopting hydrocarbon refrigerant, OKA produces more efficient, more environmentally sustainable, less toxic and higher performance AC systems all at a lower price.
