MORE CLIMATIC COMFORT IN PASSENGER CARS

In modern passenger cars with large window areas, which allow considerable penetration of solar radiation into the passenger compartment, it is particularly important to be able to control adequately the temperature in the area around the occupants' heads. This is usually done by means of the central outlets in the console. In theory, if there are several possible settings for the climate control system, it should be possible to achieve optimum comfort in all weather conditions; however, there is always the risk that many occupants will make operating errors. If cold air is blown out of the center outlets directly, then the temperature can be regulated on both sides without any problem and any operating errors are avoided. In systems where the temperature is adjusted manually, temperature control is achieved mainly by mixing the air. In this case, the center outlet is supplied with warm air so that the comfort level can be increased in a variety of weather conditions. With fully automatic air conditioning systems, the temperature of air coming from the center outlets needs to be regulated carefully. Exceptional comfort can be achieved by vehicles offering the possibility for individual adjustment of this air temperature and with it, also the temperature stratification of the car.
