夏热冬冷地区某大型铁路客站自然通风适用性研究

摘要

以南京某车站为例,应用Visual ESP-r软件模拟了设计工况下其主要功能区域(候车大厅、进站集散厅)在自然通风情况下的全年动态自然室温状况,并与自然通风条件下的热舒适标准进行了比较,以确定其自然通风时间,研究能否利用自然通风缩短空调使用时间,达到降低能耗的目的；在此基础上对建筑围护结构进行了优化,得出了建筑围护结构对自然通风可利用时间的影响程度.%Taking a railway station in Nanjing as example, using the software Visual ESP-r, simulates the dynamic annual indoor temperature of the main function zones such as the waiting room and passenger distribution hall with natural ventilation in design conditions. Compares the result with the data obtained by thermal comfort standards under natural ventilation conditions to determine the hours when the natural ventilation is effective in the railway station and analyses whether the air conditioning time can be shortened by using natural ventilation. Then optimizes the building construction to analyse its effect on natural ventilation hours.
