According to the airliner airflow organization system with the cabin interior humidifying and cabin wall moisture-proof functions, improvement is carried out on the basis of an existing double-layer mixed ventilation system, the humidifying mechanism and the moisture-proof air supply mechanism are additionally arranged, and the newly-added mechanisms are different in a narrow airliner and a wide airliner. For a narrow-body passenger plane, a luggage rack is added for humidifying and supplying air to a passenger area in an inclined manner, and a side cabin wall is added for supplying air to the lower part of the side cabin wall and supplying dry fresh air to wash the cabin wall for cabin wall moisture prevention. For a wide-body passenger plane, a main pipe humidifying device is additionally arranged in a cabin main pipe to humidify supplied air of a cabin in a centralized manner; side cabin wall lower portion air supply and cabin upper portion space moisture-proof air supply are added, and dry fresh air is delivered to wash the side cabin wall, a cabin baggage holder and a cabin ceiling for cabin wall moisture prevention. According to the invention, while a passenger area is humidified, an air curtain area with relatively low humidity can be built near the cabin wall, so that low-humidity discomfort caused by an existing mixed ventilation design is reduced, and the water content in seepage air at the cabin wall in the cabin is effectively reduced.
本发明提供一种具有舱内加湿和舱壁防湿功能的客机气流组织系统,在现有双层混合通风系统的基础上进行改进,增加加湿机构和防湿送风机构,且新增机构在窄体客机和宽体客机内有所不同。对于窄体客机,增加行李架加湿送风向乘客区域倾斜投送加湿空气,增加侧舱壁下部送风投送干燥新风冲刷舱壁,用于舱壁防湿。对于宽体客机,在座舱干管内增加干管加湿装置对座舱送风进行集中加湿;增加侧舱壁下部送风和座舱上部空间防湿送风投送干燥新风冲刷侧舱壁、座舱行李架和座舱天花板,用于舱壁防湿。本发明为乘客区加湿的同时,能够在舱壁附近营造相对湿度较低的风幕区,减少现有混合通风设计带来的低湿度不舒适感,并有效降低座舱内舱壁处渗风中的含水量。
