1 、 exhaust fan optional centrifugal fan or high temperature axial fan. The ordinary centrifugal fan can meet the requirements of exhaust and smoke exhaust, but the large air volume centrifugal fan can only be installed on the ground, and occupies a larger area, so it needs a larger computer room.
2, high temperature axial flow fan for fire special fan, also can satisfy the operation of 30min at 280 DEG C, smoke temperature, high temperature and 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.
3, reasonable arrangement of the ventilation pipe exhaust pipe and the air 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.
4, 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; the outlet position should be higher than that of the floor, in order to reduce the influence of ventilation on the ground environment.
5, the 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, so use a ventilation pipeline system should meet the requirements of the air exhaust and smoke usually fire.
