地铁通风空调系统新观点
Updated insights on ventilation and air conditioning system in underground railway
摘要：
通过对常规地铁通风空调各系统的功能及运行策略的分析比较，指出了常规系统存在的问题，提出了优化建议。指出可通风屏蔽门制式集成了屏蔽门系统和开闭式系统的优点，基本适用于各温度区，具有明显的优势和可行性；隧道通风系统存在通风不利的工况，轨行区排热系统及运行策略、活塞风运行策略和阻塞工况运行策略均有优化的必要；车站公共区和设备管理用房采用分散送风方式具有较大的节能性、经济性和其他优势。
Abstract：
By comparison and analysis on the system function and operation strategy of conventional ventilation and air conditioning system in underground railway, discovers some problems in the conventional system, and proposes the suggestions on system optimization. Points out that the advantages in both of screen door system and open-closed system are concentrated in the system of ventilative platform screen door. This system is basically fit for all temperature zones and of great advantage and feasibility. Unfavorable working conditions of ventilation exist in the ventilation system of tunnel, so it is necessary to optimize the rail heat rejection system, as well as the operation strategies of rail heat rejection system and piston air system and the operation strategy in blocking condition. The separated air supplying system in public area and equipment room in stations has great advantages in energy saving, economy and other aspects.
