火车站候车厅夏季热舒适性研究

摘要

对西安火车站候车厅室内热环境舒适度进行了现场调查和分析。结果表明，候车厅内平均空气温度较高，人们的热感觉普遍偏热。夏季实测热中性温度27.1℃，期望温度27.68℃，80％可接受的热舒适温度范围为24.45～30.6℃，比ASHRAE标准规定的舒适区温度范围要宽的多。分析得到的热中性温度和热舒适温度范围可为火车站改扩建在暖通空调系统的节能设计方面提供一定的参考。%Investigates and analyses the indoor thermal comfort of the Xi'an station waiting room.The results showed that the indoor average air temperature was high , the slant generally feel was hot.The tested neutral temperature was 27.1℃and the preferred temperature was 27.68℃, 80%acceptable comfortable temperature range was 24.45 ~30.6℃, it was wider than the comfort temperature zone in ASHRAE 55 standard.The range of neutral temperature and thermal comfort temperature from the analysis can provide certain reference to the energy saving in railway sta -tion reconstruction of HVAC systems.
