地铁车站通风空调系统优化设计探讨

Research on Optimized Design of the HVAC System in Subway Station

以缩小地铁车站规模、减少工程投资为出发点,在满足地铁车站通风空调系统基本功能的前提下,通过对地铁隧道通风系统和空调水系统遇到的设计问题进行总结,提出优化设计方案供设计参考。隧道通风系统可通过设置单活塞风井来压缩车站规模,减少活塞风亭对车站周围环境的影响。同时特殊区段的隧道通风系统,可在充分了解地铁隧道通风系统原理的基础上优化系统设计,降低车站土建规模、避免对重要场合周围建筑景观的影响。地铁车站空调水系统可以选择设置集中冷站和采用新型制冷设备等方式来减小冷水机房的面积。

Basing on the purpose of reducing the building scale and investment on the construction of subway and meeting with the basic demand of ventilation and air-conditioning system in the subway station, this paper presents some optimized schemes for designer to refer to by means of generalizing the issues of the tunnel ventilation system, air-conditioning water system etc in the progress of design. Single piston shaft can be applied in optimized tunnel ventilation system to reduce the scale of subway station and the influence upon the surrounding environment. Meanwhile, as the particular occasions are concerned, the tunnel ventilation system can be optimized though complete understanding the principle of the system, which will reduce the scale of subway station and the influence on the important architecture landscape. The area of air-conditioning cooling water engine room on the subway station can be reduced by applying integrate cooling station and new cooling equipment.
