旅客运输机座舱空气品质及乘客热舒适调查研究

目的评价飞机巡航中客舱内环境参数及乘客热舒适性。方法对空气温度,相对湿度,风速,客舱内压力,噪声等级,二氧化碳,一氧化碳和挥发性有机化合物(TVOC)等污染物浓度进行了测试,并对乘客进行问卷调查,针对热环境、污染物、气压和总体环境满意度分别设计合适的问卷量表和问题。结果飞机客舱内温度冬季偏热,相对湿度偏低,二氧化碳浓度和TVOC浓度超标。乘客满意度调查中,噪声是影响乘客满意度的最大因素。结论目前的参数设定基本满足适航条例要求,座舱内空气净化和加湿以及噪声控制仍需改进。

Air Quality and Passengers Thermal comfort Investigation in Aircraft Cabin

Objective Inflight test and subjective investigation in the aircraft cabin were carried out. Methods En- vironmental parameters such as air temperature, relative humidity, air velocity, pressure, noise level, carbon diox- ide, carbon monoxide and TVOC concentration were tested during the flight. Passengers were asked to vote their sen- sation and perception of the cabin environment with respect to thermal environment, contaminant, air pressure, sound level, overall satisfaction and their perceived symptoms. Results It shows that in winter, temperature rises, humidity relatively low, and carbon dioxide and TVOC concentration do not meet relevant standards. Noise level is the most in- fluencing factor of passengers＂ overall satisfaction. Conclusion All parameters meet the airworthiness regulation. Air purifying and humidifying and noise control still need improvement.
