旅客机新型座舱空气质量控制系统仿真研究

旅客机座舱空气质量关系到机组成员和乘客的安全、健康和舒适,座舱内空间狭小,人员密集,旅客不能按意愿随意走动,因此座舱空气质量与地面建筑环境不同。针对旅客机独特的座舱环境,提出一种新型的主动与被动控制策略相结合的座舱空气质量控制系统。为研究空气质量控制系统的效果,通过合理的分析与简化,应用集总参数法建立了座舱空气质量变化的动态特性模型,根据动态特性模型对座舱空气质量控制策略进行了仿真分析,仿真结果表明:新型座舱空气质量控制策略可以起到降低座舱空气质量变化幅度、改善旅客机座舱空气质量的作用。

Simulation Research of Air Quality Control System of New Airliner Cabin

The airliner cabin air quality is related to the safety, health and comfort of passengers and cabin crew. Compared with other indoor environments, such as homes and offices, the cabin environment is different in many respects-for example, the high occupant density, and the inability of occupants to leave at will. Considering the unique cabin environment, a new cabin air quality control system based on active and passive control strategy was described. In order to investigate the applying effects on cabin air quality control system, a dynamic model for cabin air quality was established, by means of Lumped Parameter Method with physical analysis and logical simplification. According to the model, the control strategy of cabin air quality was simulated and analyzed. Simulation results indicate that the cabin air quality change extent of controlled object is wonderfully reduced and the airliner cabin air quality is also improved.
