METHOD AND DEVICE FOR AIR CONDITIONING VEHICLES, ESPECIALLY AIRPLANES

摘要

The invention relates to a method for air conditioning vehicles, especially aircraft, in which the airflow supplied to the passenger cabin (K) is comprised of optionally tempered outside air and a portion of recirculated air. The inventive method is characterized in that the recirculated air portion of the supplied airflow is limited by means of at least one CO2 sensor in such a way that the CO2 portion of the air in the passenger cabin does not exceed a determined limit. The amount of recirculated air in the supplied airflow can alternatively or additionally be regulated below the limit value prescribed by the CO2 sensor such that the relative humidity is maintained within a humidity range which is higher than the relative humidity of the supplied outside air after it has been heated up to room temperature, and such that the supplied airflow is introduced into the passenger cabin through at least one filter.
