轨道交通盾构型车站公共区空调通风系统方案研究

Study on Air Conditioning and Ventilation System Scheme for Public Area of TBM Bored Rail Transit Station

轨道交通盾构型车站相比明挖、暗挖、矿山法车站,有着完全迥异的车站建筑布局。针对盾构型车站狭长、内部空间局促、管线压力大等特点,采取分散式空调加新风系统,根据公共区负荷特点,合理布局冷源位置。在气流组织上,采用流体力学模拟方法,提出了适合盾构型车站的空调通风方案。

The architectural layout of TBM bored rail transit stations is completely different with that of the stations constructed by cut and cover method or mining method. The TBM bored station is arrow and long, with constricted internal space for pipeline installation. The decentralized air conditioning plus fresh air system is preferred. According to the load characteristics of the public area, the locations of the cold sources are reasonably set. In terms of airflow organization, the fluid dynamics simulation method is used to obtain the optimal air conditioning and ventilation scheme for TBM bored stations.
