中小型地下车库无风管通风排烟系统设计

Design of Induce Ventilating & Smoke Exhausting System Without Duct in Small or Middle Scale Underground Garage

与传统的地下室通风排烟系统不同,本文介绍了一种住宅区中小型地下车库的无风管通风排烟系统设计。该设计平时采用诱导通风系统合理组织气流,火灾时转入排烟系统,排风口与排烟口、排烟机与排风机均合用,两个系统合二为一。因排风、排烟口设置在通风井道侧墙处,没有水平风管设置,可有效降低地下室层高。

Unlike the traditional ventilating and smoke exhausting system,the paper introduced a design of induce ventilating ＆ smoke exhausting system without duct in the small or middle scale underground garage. In this design, induce ventilating was adopted in normal time and smoke exhausting was adopted in fire time. The outlet and fans of the ventilating and smoke exhausting were used at the same time. There is no level duct in the garage because outlets were set up on the side wall of the ventilation well, thus the height of the ground floor can be decreased.
