Passenger comfort and ventilation efficiency in cars have attracted the attention of scientists and car manufacturers during the last years due to their potential of improving thermal passenger comfort, increasing efficiency and attended energy reduction. Nowadays, state of the art for the ventilation of passenger compartments of cars is mixing ventilation (MV) which is based on a high mixing degree of inflowing air with cabin air. In cooling cases, this is realized by high-momentum jets of cold air, which enter the cabin at the dashboard. Among the potential benefits of new developed ventilation concepts, are an increased thermal passenger comfort by reducing draughts and simultaneously energy saving potential by increasing the heat removing efficiency (HRE). The latter is of great importance especially for electrically powered cars to improve their range.
