地铁车站运营过程中的能耗问题一直是影响地铁经济效益的关键问题之一。GB 50157—2003《地铁设计规范》实施之后，车站通风空调系统的节能有了新的途径。对地铁车站设备管理用房空调设计中新风量的取值进行了具体的分析比较。新标准解决了目前工程设计中普遍存在的新风量取值偏大、从而导致新风冷负荷占空调负荷比例过大的问题。该标准在武汉地铁二号线设计中取得了良好的效果。

 Energy consumption in Metro station operation is one of the key factors that always influence the economic efficiency of Metro. The implementation of Design Standard for Energy Saving of Public Building brings new approaches to save the energy of the ventilation and airconditioning system of Metro stations. The volume of fresh air required in the design of the airconditioning system of the equipment management rooms of Metro station is analyzed. The standard solves the problem that large volume of fresh air, which can result in high proportion of the fresh air cooling loads in the air conditioning load, is always adopted in the current project design. The standard has achieved good effect in the design of No.2 Line of Wuhan Metro.
