1.根據(jù)通風(fēng)設(shè)備廠家介紹,地下室通風(fēng)方式合理布置排風(fēng)管及排風(fēng)口,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)。

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.

每個通風(fēng)設(shè)備、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。

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。所以使用一套通風(fēng)設(shè)備時系統(tǒng)應(yīng)滿足平時排風(fēng)與火災(zāi)時排煙要求。

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,也可以進行通風(fēng)管道安裝,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,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。

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.
