摘要
对地下综合管廊的除湿模式下的通风模式进行了研究,采用CFD方法对不同送回风口布置下的廊内湿度控制效果进行了模拟计算,结果表明,对于湿负荷分布于四周壁面的狭长管廊,最佳送风方式是送回风口布置在管廊的两端,形成一送一回的活塞气流。独立除湿机的影响范围有限,如不借助风管难以实现廊内湿度的控制。此外,廊内管线布置会影响气流组织,增加壁面气流死区,增大壁面的结露风险,设计中应当予以重视。
The paper discusses the optimization of the ventilation strategy for dehumidification inside the urban utility tunnel using CFD technique.Humidity distributions are simulated with different layouts of the supply and return vents.The results show that the best strategy is to place the supply and return vents at the two ends of the tunnel to form a piston flow.Using commercial dehumidifiers alone without the aid of ducts can hardly control the humidity in the long tunnels because the single unit has very limited impacted space.In addition,the cables and ducts inside the tunnel have significant impact on the airflow and should be given consideration in the design of the dehumidification ventilation system.
