As a low-carbon, green, energy-saving and environment-friendly ventilation equipment, the low-profile ventilator has gradually become the supporting equipment of the plant roof, which can provide practical functions such as ventilation, fire smoke exhaust and natural daylighting for the plant. According to different appearance characteristics, the skylight of the plant can be divided into thin ventilation skylight, arced daylighting ventilation skylight and electric smoke exhaust ventilator. Today, I will briefly introduce three types of smoke vent.
1、 Low-profile ventilator
The appearance of the daylighting skylight of the thin plant is rectangular. It is called thin because of its low height. This type of natural ventilator has good wind resistance and can resist typhoon of level 15 at most. It is suitable for areas with large wind load. At the same time, it has good ventilation, lighting and smoke exhaust performance, small self weight load, less steel consumption and high comprehensive cost performance.
2、 Arc shaped daylighting and ventilation skylight
The overall appearance of arc-shaped continuous rooflight is circular arc. According to different layout, it can be divided into ridge ventilation skylight and slope ventilation skylight. The former generally has larger throat size, so it has better ventilation and smoke exhaust performance; The latter generally has a small throat size, which can provide uniform daylighting, ventilation and smoke exhaust for the plant.
3、 Electric daylighting smoke ventilator
The electric lighting and smoke exhaust skylight not only has good lighting, ventilation and smoke exhaust functions, but also its ventilation and smoke exhaust volume can be adjusted through the opening angle of the electric control skylight. At the same time, it can also be linked with the fire control, which provides an important guarantee for the fire safety of the plant.
