Air conditioning system operating method for vehicle i.e. motor vehicle, involves cooling to-be-conditioned air, determining humidity mass and utilizing determined humidity mass for determining humidity of air-conditioned air

摘要

The method involves cooling to-be-conditioned air based on humidity of air-conditioned air. Humidity mass determined as mass at water per mass in dry air is determined based on a measured value which is detected by a condensation sensor. The determined humidity mass independent of the temperature of air is utilized for determining the humidity of air-conditioned air. An air conditioning system is operated in a reheating operation, when the humidity mass exceeds a value of 11.5 gram of water per 1 kg of dry air. An independent claim is also included for an air conditioning system comprising a humidity determining device.
