基于问卷调查和现场测试的麦加轻轨站台热环境研究

为评测高温干燥沙漠气候环境中开放式站台在空调状态下的热环境,实测了站台空气温度、平均辐射温度、空气相对湿度及空气流速等热环境参数,进行了基于ASHRAE七级热感觉标尺的热舒适调查问卷.测量及调查结果表明,站台环境热中性温度为31.0℃,高于ASHARAE推荐热舒适温度;80％满意度时的可接受温度范围为27.7℃,34.3℃],较ASHRAE推荐温度范围更宽.

The Research of the Thermal Environment based on the Measurement and Questionnaire on Platform in Makkah Metro Project

To evaluate the thermal environment with AC system running on platform located in hot and dry environment,a typical desert climate,which is exposed to open space,the key parameters of thermal environment including the dry bulb temperature,mean radiant temperature,relative humidity and velocity of air blow are tested and the questionnaire for thermal comfort following the ASHRAE 7 sensations scale are done among the passengers by random.From the results of survay and analysis the neutral temperature for platform thermal environment is 31.0℃C which is higher than the recommended comfort temperature by ASHRAE standard and the acceptable comfort temperature range is 27.7 ℃,34.3 ℃] which is wider compared with the recommended temperature range by ASHRAE standard under the condition of PPD≤20％.
