Problems solved by technology
[0005] In addition, a recirculation system operating at maximum compensation leads to a decrease in the comfort of passengers in the aircraft cabin
On the one hand, fans operating at full load cause turbulence in the flow of air drawn from areas of the aircraft cabin that need to be air-conditioned, thereby increasing noise emissions
On the other hand, flow conditions that create localized uncomfortable drafts in areas of the aircraft cabin that need to be air conditioned
Finally, when the recirculation system is operating at maximum compensation, the actual air flow drawn by the failed fan during normal operation of the system from the area of the aircraft cabin that needs to be air-conditioned is not taken into account

Embodiment Construction
[0034] figure 1 The illustrated system 10 for conveying recirculated air from an aircraft cabin comprises ten conveying devices 12a-17j constructed in the form of low-pressure fans. The conveying devices 12a-12j are arranged in a distributed manner along mutually facing side walls of the aircraft cabin area 14 to be air-conditioned. Depending on the equipment of the aircraft cabin area 14 that needs to be air-conditioned in the area of each conveyor 12a-12j, each conveyor 12a-12j operates with a different conveyor output when the recirculation system 10 is operating normally. The transfer devices 12a and 12f remove only 100 l / s of air flow from the aircraft cabin area 14 to be air-conditioned during normal operation of the recirculation system 10, while the transfer devices 12b, 12c, 12e, 12g, 12h and 12j are recirculating The system 10 operates with a transfer output of 200 l / s in normal operation, whereas the transfer devices 12d and 12e even operate with a transfer outpu...

A system (10) for conveying recirculation air from an aircraft cabin comprises a plurality of conveying devices (12a-12j) which are arranged in a manner distributed along an aircraft cabin region (14). A control device (16) is configured to control the conveying devices (12a-12j) in the normal operation of the system (10) in such a manner that each conveying device (12a-12j) removes a predetermined air volume flow from the aircraft cabin region (14). The control device (16) is furthermore configured to control, in the event of a failure of a conveying device (12c), at least some of the remaining still functional conveying devices (12a, 12b, 12d-12j) in such a manner that the entire air volume flow removed from the aircraft cabin region (14) by the remaining still functional conveying devices (12a, 12b, 12d-12j) is increased by an amount corresponding to an air volume flow amount removed from the aircraft cabin region (14) by the failed conveying device (12c) in the normal operation of the system (10).
Description
technical field [0001] The present invention relates to systems and methods for delivering recirculated air from an aircraft cabin. Background technique [0002] The cabin of a modern airliner is usually air conditioned both in flight and on the ground by means of the aircraft's own air conditioning system. The aircraft air-conditioning system is supplied with discharge air taken from the engine compressor or the auxiliary power unit compressor and is cooled to the desired low temperature in the air-conditioning unit, the so-called air-conditioning group of the aircraft air-conditioning system. The cooled air in the air-conditioning group of the aircraft air-conditioning system is fed into a mixer where it is mixed with recirculated air drawn from the aircraft cabin by the recirculation system. The mixed air produced in the mixer, which is composed of fresh cold air provided by the air conditioning unit and recirculated air drawn from the aircraft cabin, is finally fed into...
