Aircraft air conditioning system and method of operating an aircraft air conditioning system

An aircraft air conditioning system comprises a plurality of temperature zones and at least one door. Comprises an air-conditioning unit configured to condition and provide air to at least one of the plurality of temperature zones, temperature zone sensors each associated with a temperature zone for measuring the temperature therein, and a control unit. The control unit receives information representing the closing state of a cabin door, and is coupled to the temperature zone sensors and configured to control the temperature of the conditioned air provided to at least one of the plurality of temperature zones in two operation modes. In a first mode, when doors are closed, the temperature control depends on the measured temperatures in the temperature zones. In the second mode, it depends on a set-temperature, independent of the measured temperature in a temperature zone affected by an open door.

Air-conditioning system for an aircraft, and method for an aircraft

In a method for controlling an aircraft air conditioning system, a heating or cooling demand of an aircraft region to be air conditioned is determined. A volume flow of recirculation air discharged from the aircraft region to be air conditioned and a volume flow of compressed air into a mixing chamber of the aircraft air conditioning system is controlled such that the heating or cooling demand of the aircraft region to be air conditioned is met, while the volume flow of compressed air into the mixing chamber of the aircraft air conditioning system is minimized.
