大型客机座舱环境舒适性评价
Comfort evaluation of cabin environment in commercial aircrafts
摘要：
针对座舱环境中不满意度较高的3个环境因素——温度、空气品质和噪声，采用客观参数测量和主观问卷调查相结合的方式，研究三者之间的相互影响。通过控制单一变量以营造真实巡航中出现的温度场、浓度场和噪声场，受试者分别在每个工况下对座舱环境满意度进行评价。结果表明：舱内二氧化碳浓度升高、噪声声压级变大均会使受试者感觉更暖；各项满意度百分比显示噪声、空气品质和温度三者之间会相互影响，而噪声是座舱环境中最不满意的因素。
Abstract：
Temperature, air quality and noise are the top 3 dissatisfied factors in current cabin environment. Studies the interaction of three factors by the combination of objective parameter measurements and subjective questionnaires. By controlling the single variable, creates temperature field, concentration field and noise field in real cruise. Evaluates the volunteers’ satisfaction with the cabin environment in each condition. The results show that when the indoor carbon dioxide concentration and the noise level increases, the volunteers feel warmer. The data of satisfaction percentages show that noise, air quality and temperature interact with each other, and noise is the most dissatisfied factor among three factors.
Keywords:cabin environment, comfort, temperature, air quality, noise, satisfaction
