1.系統(tǒng)的劃分排煙系統(tǒng)防煙分區(qū)劃分應(yīng)結(jié)合建筑防火分區(qū)來(lái)考慮，做到既有利于地下室通風(fēng)系統(tǒng)兼作排煙系統(tǒng)，又不會(huì)出現(xiàn)排煙風(fēng)管跨越枋火分區(qū)現(xiàn)象。所以使用一套風(fēng)管時(shí)系統(tǒng)應(yīng)滿足平時(shí)排風(fēng)與火災(zāi)時(shí)排煙要求。
Division 1 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, the use of a set of air duct system should meet the usual exhaust and fire smoke requirements.
2.地下室通風(fēng)方式合理布置排風(fēng)管及排風(fēng)口，平時(shí)排風(fēng)用，火災(zāi)時(shí)兼作排煙風(fēng)管及排煙口;地下一層考慮由車道自然進(jìn)風(fēng)，其它層由平時(shí)送風(fēng)系統(tǒng)兼作火災(zāi)時(shí)補(bǔ)風(fēng)系統(tǒng)。每個(gè)排風(fēng)、排煙及送風(fēng)系統(tǒng)應(yīng)設(shè)置豎井，進(jìn)風(fēng)口應(yīng)設(shè)在地面潔凈處，若能與地下主樓有一定距離更好，其受火災(zāi)氣影響會(huì)小;若能與地面主樓有一定距離更好，其受火災(zāi)煙氣影響會(huì)小，排風(fēng)口位置應(yīng)高于附樓層面， 以減少排風(fēng)對(duì)地面環(huán)境影響。
2 basement ventilation arrangement of exhaust pipe and exhaust outlet, usually used as fire exhaust, exhaust air duct and exhaust port; the underground layer considered by Lane natural ventilation, the other layer is composed of normal air ventilation system as fire system. Each wind and smoke exhaust and air supply system should be set up into the air shaft, should be located in the ground clean, if there is a certain distance from the main building and better underground, gas fire impact will be small; if there is a certain distance from the ground and better building, the fire smoke effect will be small, the air outlet position should be higher than that of floor level, in order to reduce the influence of ventilation on the ground environment.
3.排風(fēng)、排煙及送風(fēng)風(fēng)機(jī)選型排風(fēng)、排煙風(fēng)機(jī)可選離心風(fēng)機(jī)或者高溫軸流風(fēng)機(jī)。普通離心風(fēng)機(jī)即可滿足排風(fēng)排煙要求，但大風(fēng)量離心風(fēng)機(jī)只能安裝在地面，占地較大，需要較大機(jī)房，高溫軸流風(fēng)機(jī)為消防專用風(fēng)機(jī)，也能滿足在280℃ 煙溫下運(yùn)行30 min的要求， 而高溫軸流風(fēng)機(jī)體積小，一般可吊裝，若設(shè)機(jī)房面積也小，實(shí)際工程設(shè)計(jì)中，往往采用高溫軸流風(fēng)機(jī)排煙。
3 exhaust, exhaust and air supply fan type exhaust fan, exhaust fan optional centrifugal fan or high temperature axial flow fan. To meet the requirements of ordinary exhaust smoke centrifugal fan can be, but the 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, smoke temperature, high temperature and axial flow fan body size general to be lifted, if room area is small, the actual engineering design, often using high temperature axial flow fan exhaust.
