地铁车站通风空调大系统的节能设计

Energy-saving Design of Ventilation and Air-conditioning System of Metro Station

通过对带有屏蔽门的地铁车站公共区通风空调系统负荷特点、新风量取值等进行分析,提出公共区通风空调设备四种配置方案;经过技术经济比较,提出大系统空调器按远期配置,小新风机按近、远期配置,回排风机按近期匹配风量配置的推荐方案。该推荐方案初期投资少,节能效果明显,易于实施。

Through an analysis of the loading characteristic and the fresh air value of ventilation and air-conditioning system in the public zone of metro station,which is equiped with platform screen doors, this paper puts forward four projects of ventilation and air-conditioning device configuration, from them a commendatory protect is selected through technical an economical comparison and analysis. The authors argue that the effect of energy saving of this project is obvious and deserves wider application.
