  • Air conditioning installation with activated carbon filter
    Patent number: 6199397
    Abstract: An air conditioning installation is supplied with an activated carbon filter for cleaning the air to be supplied to the interior of a motor vehicle. A device is provided for cleaning the air filter and the air therein by heating, and air laden with by-products may be driven out of the filter by means of a cleaning airflow. The activated carbon is in physical contact with a temperatureregulated or temperature controlled heating device, with which the activated carbon and the air present in the filter can be heated, while the cleaning airflow flows through the filter.
