排風(fēng)、排煙及送風(fēng)風(fēng)機選型排風(fēng)、排煙風(fēng)機可選離心風(fēng)機或者高溫軸流風(fēng)機。山東通風(fēng)管道加工普通離心風(fēng)機即可滿足排風(fēng)排煙要求，但大風(fēng)量離心風(fēng)機只能安裝在地面.

　　Exhaust air, smoke exhaust and air supply fan type selection, exhaust fan, exhaust fan optional centrifugal fan or high temperature axial fan. The common centrifugal fan can be used in the ventilation pipe of Shandong to meet the requirements of exhaust and smoke exhaust, but the centrifugal fan with large air volume can only be installed on the ground

　　占地較大，需要較大機房，高溫軸流風(fēng)機為消防專用風(fēng)機，也能滿足在280℃ 煙溫下運行30 min的要求， 而高溫軸流風(fēng)機體積小，一般可吊裝，若設(shè)機房面積也小，實際工程設(shè)計中，往往采用高溫軸流風(fēng)機排煙。

　　Covers an area of large, large room temperature, axial flow fan for fire special fan, also can meet the 30 min running at 280 deg.c temperature and smoke, 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 the exhaust smoke.

　　地下室通風(fēng)方式合理布置排風(fēng)管及排風(fēng)口，平時排風(fēng)用，火災(zāi)時兼作排煙風(fēng)管及排煙口;地下一層考慮由車道自然進風(fēng)，其它層由平時送風(fēng)系統(tǒng)兼作火災(zāi)時補風(fēng)系統(tǒng)。

　　The ventilation mode of the basement of reasonable 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.

　　每個排風(fēng)、排煙及送風(fēng)系統(tǒng)應(yīng)設(shè)置豎井，進風(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)煙氣影響會小，排風(fēng)口位置應(yīng)高于附樓層面， 以減少排風(fēng)對地面環(huán)境影響。

　　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.

　　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)管時系統(tǒng)應(yīng)滿足平時排風(fēng)與火災(zāi)時排煙要求。

　　The smoke exhaust system division 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 air duct, the system should meet the requirements of smoke exhaust in peacetime exhaust and fire.
