Fire exhaust fan exhaust volume minimum space requirements for fire exhaust fan is an important high-rise buildings smoke ventilation equipment, plays a very big role. With the increase in the application market, there have been various types of fans, but because of the special role of fire exhaust fan, temperature exhaust fan, the performance requirements are the same, the amount of smoke exhaust fan fire space needs to meet the following Requirements to be able to play its role effectively. 1. an exhaust smoke partition or headroom greater than 6.0m is not zoned smoke partition room, per square meter area shall be not less than 60m3 / h Computing (single wind turbine should be less than the minimum amount of smoke 7200m3 / h) 2. two or more partitions exhaust smoke, the smoke partition should be the maximum area per square meter of not less than 120m3 / h calculation. 3. atrium volume is less than 17,000, the amount of smoke six times its volume / h ventilation calculation; atrium volume greater than 17,000, its exhaust volume four times its volume / h ventilation computing; but the minimum row not less than the amount of smoke 102000m3 / h. 4. The Inter-rise building stairwell and front room, elevator before the fire room or shared room, exhaust fan, use more parts when the podium outside the window can be opened for natural smoke, skirt part does not have natural draft When the conditions, the front room or shared room should be set local mechanical exhaust facilities, which according to the amount of smoke per square meter less than the front room 60m3 / h calculation. Fire exhaust fan in the smoke control system should be how to properly use? Fire exhaust fan is a good fire-fighting equipment, each building on the essential, however, for the distribution of fire smoke axial fans use, many consumers do not regulate the operation, the following small series of fire row Smoke axial fan distribution operations specifications detailed explanation below. First, fire exhaust fan supply and distribution reach of tall buildings load level requirements. Some power lines are not connected to the fire power from the probe, but is connected to the floor lighting distribution box, some single-loop design and distribution lines, and some design not set the end of the supply automatic switching devices, can not reach one or two power load required special double loop. Setting a predetermined terminal automatic switching apparatus. Second, is the distribution line of fire exhaust fan installation does not meet the requirements. Some fire smoke axial fans wearing PVC plastic pipe distribution lines, and some did not wear metal pipe brush fire retardant paint, fire performance does not meet the requirements to wear tube. 1. podium of tall buildings between stairwell and front room, HTF exhaust fan, fire elevator before the room or shared room, when the skirt portion may be opened outside the window over natural smoke, do not have the skirt portion When natural draft conditions, the front room or shared room fails to set a positive pressure air supply system specifications. 2. No more than 20 meters of natural smoke inside aisle, some designers because of its associated stairwell before the chamber has natural ventilation, considered to have a natural draft conditions, failure to specifications mechanical exhaust facilities .
