新广州火车站自然通风潜力分析
Potential analysis of natural ventilation in the New Guangzhou Railway Station
摘要：
运用多区域网络模拟工具ContamW对新广州火车站进行了自然通风设计优化。优化结果为：当室外温度低于21 ℃时，只需自然通风即可满足室内通风换气和热舒适要求；当室外温度为21～28 ℃时，可自然通风区域首先利用自然通风，当室温不能保证时再开启空调降温，其他区域运行空调系统降温；当室外温度高于28 ℃时，全部空调系统运行，建筑门窗处于关闭状态。
Abstract：
Optimizes the natural ventilation design of the station using multi-zone network simulation toolkit ContamW. The optimization results reveal that when the outdoor temperature is lower than 21 ℃, indoor air exchange rate and thermal comfort can be satisfied simply by natural ventilation, while when the outdoor temperature ranges from 21 ℃ to 28 ℃, natural ventilation should be used by preference and the air conditioning system be used as an auxiliary to natural ventilation zones, the air conditioning systems of other zones run to lower the temperature, and when the outdoor temperature is higher than 28 ℃, all air conditioning system run and the doors and windows of the building should be kept closed.
