Abstract

The below-deck space of an aircraft may be selectively configured as a freight hold or alternatively as a passenger sleeping cabin space by arranging a sleeping cabin container therein. An air conditioning system for this below-deck space provides air in a supply air main line (31), which branches off to at least one supply air delivery line (19). A first flange (23) is provided at the end of the supply air delivery line (19), and a seal collar (25) seals the end relative to the freight hold wall (29). When a sleeping cabin container is to be arranged in the below-deck space, a flap door (24) is pivoted into an open position, and the flange (28) at the end of a ventilation duct (27) of the sleeping cabin is connected directly to the flange (23). When the sleeping cabin container is removed from the freight hold, the flap door (24) is pivoted into a closed position, in which it covers the mouth opening of the flange (23), and allows an air flow into the freight hold only through the smaller restricted cross-section of an air throughflow opening (26) in the flap door (24). The air supply arrangement can be easily adjusted to meet the different air flow requirements of the sleeping cabin configuration and the freight hold configuration without requiring any recalibration of the air-conditioning system itself.
