Method for controlling the temperature of feed air injected into at least one cabin zone of a passenger aircraft, the temperature of injected feed air being controlled for each cabin zone dependent on the deviation of the injection temperature actual value of the feed air from an injection temperature target value, the injection temperature target value being established using an external ambient temperature actual value and not using a temperature sensor in the at least one cabin zone.

Method for controlling the temperature of feed air injected into the cabin zone of a passenger aircraft

A passenger aircraft includes a cabin subdivided into a plurality of cabin zones supplied with feed air from respective supply lines, a plurality of temperature sensors, and an electronic control unit coupled to the plurality of temperature sensors. The plurality of temperature sensors measures a plurality of individual ambient temperature values associated with different locations in at least one of the plurality of cabin zones. The electronic control unit derives a derived ambient temperature value for the at least one cabin zone from the plurality of individual ambient temperature values. The electronic control unit then controls a temperature of the feed air supplied to the at least one cabin zone based on the difference between the derived ambient temperature value and a room temperature target value for the at least one cabin zone.

Method for controlling the feed air temperature of a passenger aircraft

An air-conditioning system and associated method for air-conditioning an aircraft cabin including a first zone and a second zone of variable length and at least one intermediate zone is provided. The intermediate zone is selectively associated with the first zone or the second zone. Air at a first set temperature is supplied to the first zone, and air at a second set temperature is supplied to the second zone. Likewise, air at a third set temperature is supplied to the intermediate zone. A regulating device regulates the third set temperature such that if the intermediate zone is associated with the first zone, the third set temperature corresponds substantially to the first set temperature; but if the intermediate zone is associated with the second zone, the third set temperature.

Aircraft air-conditioning system for an aircraft cabin having a plurality of zones

A device for temperature regulation of sections of the interior of an aircraft includes a controlled mixer valve for the mixing of engine bleed air and air that is cooler than the engine bleed air in order to obtain pre-tempered mixed air flowing out of the mixer valve; a distribution line connected to the outlet of the mixer valve which is connected to the respective sections by at least two supply lines; individual heating units assigned to the respective sections; sensors assigned to the individual sections for the respective actual temperatures; transmitters for the respective nominal temperatures; and a regulator unit which controls the mixer valve dependent upon the respective nominal temperatures and the respective actual temperatures in the individual areas.

Device and process for temperature regulation of sections of the interior of an aircraft

With a method for controlling the temperature of feed air which is injected into the cabin zone of a passenger aircraft, the cabin of which is sub-divided into several cabin zones supplied respectively with specially temperature-controlled feed air, the temperature of the injected feed air is controlled for each cabin zone, dependent upon the deviation of an injection temperature actual value for the feed air injected into the cabin zone in question, measured by sensors, in relation to an injection temperature optimum value. If there is no, or at least no usable reading of the ambient temperature of this cabin zone for a cabin zone, an optimum value for the injection temperature of this cabin zone can be established in accordance with a variation, whereby it is determined upon the basis of the injection temperature optimum values and/or the injection temperature actual values of other cabin zones, whereby the measurement by sensors of the cabin temperature works reliably. In accordance with another variation, the injection temperature optimum value of a cabin zone can be established without measuring ambient temperature by sensors or without reliably measuring ambient temperature from the temperature measured for the external surrounds of the aircraft.
