ShareMac news: the first service vehicle with a CO2 air-conditioning system
During the IAA Exhibition for commercial vehicles in Hanover on September 24, 2008, the German Environment Agency (UBA) presented the first service vehicle - a standard Volkswagen Touran -equipped with a CO2 air-conditioning system. According to UBA, results from first testings showed that at 28°C ambient temperature, the CO2 mobile air-conditioning (MAC) system consumes 45% less additional fuel than current systems using R-134a and at high ambient temperatures of 35°C it consumes 14% less fuel. After all tests have been completed, the CO2 car will be used as a regular service car by UBA, as a means of testing long-term reliability.
