西安地铁通风空调系统节能改造研究

根据西安市地铁车站内外环境、客流量等因素的变化,采用地铁车站环境控制及能源管理系统,对原有通风空调系统按各种不同运行工况进行节能改造,包括:空调末端负荷节能控制、空调主机热转换效率控制、通风空调系统末端送风量调节控制、风系统与水系统协调控制等。西安地铁2号线3个车站的改造后测试结果证明,对地铁节能降耗作用明显,可为同类工程的改造设计和实施提供参考。

Energy-saving Reconstruction of Xi'an Subway Ventilation and Air Conditioning System

According to the changes of internal and external environment factors,the passenger flow and different operating conditions of Xi'an subway stations,the energy-saving recon-struction in the original ventilation air conditioning system can effectively reduce subway energy consumption,including the end load energy control,heat transfer efficiency of the main engine,end air output control,wind and water systems coordi-nation and so on. The testing result of 3 stations on Xi'an subway Line 2 shows that the energy-saving reconstruction of air conditioning system is very effective,which can provide a reference for similar engineering design and application of the method.
