摘要: 地面作业过程中,机场工作人员不合理地使用地面空调将导致客舱热舒适性下降,因此应综合评估影响乘客热舒适度的客舱环境因素。根据飞机客舱环境特点,选取预测平均投票数作为客舱热舒适度评价指标,利用简化的PMV 模型,分析客舱环境因素(温度、相对湿度、空气流速)对客舱内部PMV 指标的影响。结果表明院温度对客舱热舒适度的影响最大,空气流速其次,而相对湿度对热环境的影响较小。基于PMV 指标进行客舱热环境控制,相比现有供气方式(以固定的制冷/热对飞机进行持续供冷/热)更加高效和节能。

关键词: 热舒适, PMV 指标, 客舱环境因素

Abstract: Cabin thermal comfort may decrease because of unreasonable operation of ground air conditioner during ground working, therefore the cabin environmental factors which may influence passenger爷s comfort should be comprehensively evaluated. According to the characteristics of cabin environment, PMV is selected as thermal comfort evaluation index. Employing simplified PMV model, the influence of cabin environmental factors (temperature,humidity, air flow speed) on PMV index is analyzed. Results show that cabin temperature has the greatest impact on cabin thermal comfort, air flow speed is the second factor, and humidity has least impact. Cabin thermal environment control based on PMV is more efficient and energy-saving than traditional way (constant and fixed cold/hot air supply).

Key words: thermal comfort, PMV index, cabin environmental factor
