26 June 2015

Volkswagen has ordered air conditioning systems that use CO2 for its VW Phaeton and Audi A8. In March 2013, VW, Daimler, Audi, BMW and Porsche had announced plans to develop CO2 technology as a more climate-friendly refrigerant for air conditioning systems. VW says CO2 as a refrigerant — also known as R744 — has lower greenhouse gas effect than conventional refrigerants, with a GWP (Global Warming Potential) value of 1, or 99.3% below the European Union- specified GWP limit of 150. The German automaker says thetechnology will be rolled out progressively over its entire vehicle fleet.German media sources have reported four other carmakers— Daimler, Audi, BMW and Porsche — will also switch to CO2technology in mobile air conditioning systems as an alternativeto R-1234yf.
