1.根据通风设备厂家介绍，地下室通风方式合理布置排风管及排风口，火灾时兼作排烟风管及排烟口;地下一层考虑由车道自然进风，其它层由平时送风系统兼作火灾时补风系统。

1. according to the ventilation equipment manufacturers, ventilation basement reasonable arrangement of exhaust pipe and exhaust outlet, fire smoke pipe and a smoke outlet; the underground layer considered by Lane natural ventilation, the other layer is composed of normal air ventilation system as fire system.

每个通风设备、排风、排烟及送风系统应设置竖井，进风口应设在地面洁净处，若能与地下主楼有一定距离更好，其受火灾气影响会小。

Every ventilation equipment, exhaust air, smoke exhaust and air supply system should be provided with a shaft, and the air inlet shall be located on the ground clean. If there is a certain distance from the underground main building, it will be less affected by fire gas.

2.系统的划分排烟系统防烟分区划分应结合建筑防火分区来考虑，做到既有利于地下室通风系统兼作排烟系统，又不会出现排烟风管跨越枋火分区现象。所以使用一套通风设备时系统应满足平时排风与火灾时排烟要求。

Division 2. system smoke exhaust system should be combined with the zoning of building fire zoning into consideration, so as to have a smoke exhaust system for underground ventilation system, and will not appear across the fire smoke duct Fang District phenomenon. Therefore, when using a set of ventilation equipment, the system should meet the usual exhaust and fire smoke exhaust requirements.

3.另外，也可以进行通风管道安装，普通离心风机即可满足排风排烟要求，但大风量离心风机只能安装在地面，占地较大，需要较大机房，高温轴流风机为消防专用风机，也能满足在280℃ 烟温下运行30 min的要求，而高温轴流风机体积小，一般可吊装，若设机房面积也小，实际工程设计中，往往采用高温轴流风机排烟。

3. in addition, can also meet the ventilation pipe installation, ventilation and exhaust requirements of ordinary centrifugal fan, but centrifugal air blower can only be installed on the ground, covers an area of large, large room temperature, axial flow fan for fire special fan, also can satisfy the operation of 30 min at 280 DEG C, the smoke temperature requirements high temperature, axial flow fan has the advantages of small size, can be lifted, if the room area is small, the actual engineering design, often using high temperature axial flow fan exhaust.
