摘　　要：以南京地铁南延线通风空调系统为对象,建立了地铁车站及隧道通风空调的热湿传递模型,应用地铁热环境模拟软件（STESS）进行了能耗模拟。从设备运行节能与维护保养两个角度提出了地铁通风空调运行与维护方案。模拟结果表明,改进方案能满足地铁车站与隧道的通风空调要求,全年段通风空调节电量约10%。针对夏季小新风通风空调模式出现的问题,提出了改进方案。现场测试表明,改进方案新风百分比为10%~20%,符合夏季空调小新风模式的新回风要求。3种通风空调模式可交替使用,便于通风空调设备维护与保养,该运行模式为南京其他地铁线路提供了一定的参考。Based on the ventilation and air conditioning system of Nanjing Metro South Extension,develops the heat and moisture transfer model for the ventilation and air conditioning system in underground railway stations and tunnels,and then performs the energy consumption simulation by STESS.Puts forward the schemes of operation and maintenance from the perspectives of high energy efficiency in operation and low maintenance.The simulation result shows that all of the three modified schemes can meet the demand of the ventilation and air conditioning system in underground railway stations and tunnels,which save 10% of the total electricity of the original project throughout the year period.Aiming at the malfunction in ventilation mode of fewer outdoor air rate in summer,presents the improved scheme.The field test shows that the outdoor air ratio is 10% ~20% with the improved scheme,which satisfies the demand of minimum outdoor air ventilation mode.These three kinds of schemes can be applied alternatively for better maintenance of the ventilation and air conditioning equipments.It also provides some references for other lines of Nanjing Metro.
