采用修正热舒适评价值(Corrected Predicted Mean Vote,CPMV)模型,针对实测的国内及国际航线数据进行了客舱环境的热舒适评价。结果表明,当客舱内压力满足适航标准要求范围、相对湿度明显低于舒适性要求时,低压和低相对湿度均能导致热舒适评价值(Predicted Mean Vote,PMV)的正偏移,偏移量为0.3~0.4,即低气压和低湿会使乘客感觉更温暖,但这2个参数对乘客热舒适的影响有限。短途航班热舒适性不理想,部分航班出现过热或过冷现象。
The thermal comfort of the cabin environment was evaluated according to the Corrected Predicted Mean Vote (CPMV) model for the measured domestic and international route data. The results show that both low pressure and low relative humidity lead to positive offset and offset of the Predicted Mean Vote (PMV) when the cabin pressure meets the airworthiness standard and the relative humidity is significantly lower than the comfort requirement. The amount of 0.3 ~ 0.4, that is, low pressure and low humidity will make passengers feel more warm, but these two parameters on the thermal comfort of passengers is limited. Short-term flight thermal comfort is not ideal, some flights overheating or cold phenomenon.
