Patent ID: 8490884

Claim:
A method for controlling a temperature of feed air to be injected into at least one cabin zone of a cabin of a passenger aircraft, the method comprising: independently controlling the temperature of the feed air injected into the at least one cabin zone dependent upon a deviation of an injection temperature actual value of the feed air, measured by an injection temperature sensor, from an injection temperature target value; and establishing the injection temperature target value required to maintain a set ambient temperature in the at least one cabin zone on the basis of the following conditions operated simultaneously by a control unit: using an external ambient temperature actual value of an external surrounds outside of the passenger aircraft, measured by an external ambient temperature sensor, without using a cabin zone ambient temperature actual value of the at least one cabin zone, thereby not requiring any output from an ambient temperature sensor in the at least one cabin zone; wherein the injection temperature target value for the at least one cabin zone is also established on the basis of a first correction value for the at least one cabin zone, and wherein the first correction value for the at least one cabin zone is constant and based on the physical zone-specific factors of the at least one cabin zone affecting heat transfer.
