METHOD AND DEVICE FOR AIR CONDITIONING VEHICLES, ESPECIALLY AIRPLANES

摘要

What is described here is a method of air conditioning in vehicles and in aircraft in particular, wherein the air flow supplied to the passenger cabin consists of outside air possibly heated to a moderate temperature and a fraction of circulated air.The inventive method is characterised by the provision that the fraction of circulated air in the supplied air flow is limited by means of at least one CO2 sensor in such a way that the CO2 fraction in the air in the passenger cabin does not exceed a defined threshold. Alternatively or additionally it is possible, below the threshold of circulated air as pre-determined by the CO2 sensor, to control the circulated-air fraction in the supplied air flow in such a way that the relative humidity is maintained within a humidity range which is higher than the relative humidity after heating to room temperature, and that the supplied air flow is introduced into the passenger cabin via at least one filter.
