In order to meet ever-tightening emission regulations, fuel consumption and CO2 discharge of vehicles have to be reduced drastically. Due to the rising environmental awareness the ecological aspects become increasingly important purchase criteria. Therefore, fuel saving gains particular importance in the development of automobiles. The driving comfort and safety, however, must not be affected. These various demands lead to a conflict of interests. For compliance with future emission regulations, fuel consumption of vehicles must be reduced. This is only possible by an improvement of each car component, for example the air conditioning system. At the Chemnitz University of Technology, computer programs for detailed simulation of the whole refrigeration cycle and the thermal behavior in the cabin were developed. With these, several modifications concerning the fuel saving potential can be analyzed and evaluated. Today's air conditioning compressors are driven by a constant transmission ratio by the crankshaft. A gearbox which is integrated in the compressor pulley offers a possibility for reducing fuel consumption. Depending on the engine speed and the refrigerating capacity, the compressor could be run at an operating point with lower driving power. This speed control was analyzed with the simulation programs mentioned above. The results are shown in the article.
