Problems solved by technology

As such, it can lead to the problem that the intended installation location for the temperature sensor in the cabin area does not give representative readings - because the location is in the area of ​​a local temperature peak (up or down)
[0006] Sometimes, for this reason, the actual ambient temperature for the cabin area is not available or is not reliable

Embodiment Construction

[0023] exist figure 1 In , reference numeral 10 denotes a passenger aircraft, the cabin of which is divided into several cabin areas one after the other along the length of the passenger aircraft 10 . The passenger cabin is shown here as the interior of the passenger aircraft 10 , in which the passengers and crew are located. by figure 1 In the example shown, the passenger cabin of passenger aircraft 10 is divided into six zones, the location and extent of which are given by figure 1 Arrow marks in . Here, the term passenger cabin area refers to an area of ​​the passenger cabin to which an independent air conditioning circuit is assigned for regulating the temperature of the intake air injected into the relevant passenger cabin area. Thus, the passenger cabin area can also be regarded as a temperature-regulated area.

[0024] The main supply line 12 is distributed to each cabin area and the relevant cabin area is supplied with air through this line. Corresponding to the n...

Abstract

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.

Description

technical field [0001] The invention relates to the control of air intake temperature of passenger aircraft. In this context, "control" is not limited to real control systems in which desired values ​​are set directly by means of a controlled system without feedback loops. Quite the contrary, the term "control" within the framework of the present invention also includes regulation - a regulatory difference is determined by comparing the optimum value with the recorded actual value and fed into the regulator. Background technique [0002] Good temperature regulation of the passenger cabin is important to provide passengers with a comfortable flight. In modern airliners, the cabin temperature is regulated by means of the temperature of the intake air injected into the cabin. [0003] In reality, the cabin of an airliner has been divided into several cabin areas, and each cabin area is supplied with air from its own supply line. For this purpose, each passenger cabin region ...
