Ventilation pipe is a variety of high-rise buildings are indispensable  part of the design of the ventilation pipe should follow the following  points, the following to listen carefully Kunshan ventilation pipe  technical staff is how to say it:
Smoke  system smoke partition should be combined with the building fire  partition to consider, so that both conducive to the basement  ventilation system as a smoke system, and there will not be exhaust  ducts across the Fang fire division phenomenon, so the use of a  ventilation pipe system should be To meet the usual exhaust and fire smoke requirements.
Reasonable  layout of the ventilation duct of the exhaust pipe and exhaust, usually  with the wind, the fire even as the exhaust duct and exhaust port; the  ground floor to consider the natural entrance by the lane, the other  layer from the usual air supply system as a fire Wind system. Each  exhaust, exhaust and air supply system should be set up shaft, air  inlet should be located in the ground clean place, if the underground  main building with a better distance, the impact of the fire will be  small; exhaust outlet position should be higher than Attachment level to reduce the impact of exhaust on the ground environment.
Exhaust fan optional centrifugal fan or high temperature axial fan. Ordinary  centrifugal fan can meet the exhaust smoke requirements, but the large  amount of centrifugal fan can only be installed on the ground, a larger  area, the need for larger room, high temperature axial fan for the fire  dedicated fan, but also to meet the smoke at 280 ℃ Running  under the requirements of 30min, and high temperature axial fan small  size, the general can be hoisting, if the engine room area is also  small, the actual engineering design, often using high temperature axial  fan exhaust.
