随着上盖物业开发在地铁车辆基地的普及推广,车辆基地内高大厂房无法采用自然通风,且传统的横向通风系统设置困难。针对该问题,本文提出采用高大厂房纵向诱导通风系统,并结合实际工程案例,对某车辆基地高大厂房的纵向通风系统进行了数值模拟研究。建立了诱导推射通风系统的三维模型,并分析了诱导推射风机安装间距、安装高度等对厂房内气流场的影响。模拟结果显示,上盖物业车辆基地内的高大厂房采用纵向诱导通风系统可实现较好的通风效果,为纵向诱导通风系统在工程中的应用提供了理论依据。

[Abstract]
The combination of metro vehicle base and upper property is becoming more and more, but the natural ventilation is not adopted and the traditional horizontal ventilation systems are difficult to set up? for tall and large factories in metro vehicle bases.And a longitudinal induced ventilation system which is applied to a metro tall and large factory buildings is proposed to solve the problems.Combined with a practical project, three-dimensional models of the longitudinal induced ventilation system at different installation intervals and heights in a factory building are established.And simulation is presented with different cases.The simulation results show that the longitudinal induced ventilation system can achieve good ventilation effects in tall and large factory buildings of? the covered metro vehicle base.This work will provide the basis for further project application of the longitudinal induced ventilation system.
