Patent ID: 7775447

Claim:
Method for the control of the temperature of feed air which is injected into a cabin of a passenger aircraft, whereby the cabin of the aircraft is sub-divided into a plurality of cabin zones which are respectively supplied with specially temperature-controlled feed air, the method comprising, independently controlling the temperature of the feed air injected into each cabin zone dependent upon a deviation of an injection temperature actual value, measured by an injection temperature sensor, of the feed air injected into the respective cabin zone from an injection temperature target value, establishing the injection temperature target value for each of a selected number of the cabin zones, by comparing an ambient temperature actual value, measured by an ambient temperature sensor, for the respective cabin zone with an ambient temperature target value, and establishing the injection temperature target value for at least a first cabin zone not within the selected number of the cabin zones and not having an ambient temperature sensor, based on an injection temperature target value of at least one second cabin zone different from the first cabin zone and an injection air actual temperature of the at least one second cabin zone, whereby the at least one second cabin zone is within the selected number of the cabin zones, and the injection temperature target value for the first cabin zone is established upon the basis of a first correction value which is dependent upon an ambient temperature target value for the first cabin zone, wherein the first correction value can be entered manually.
