The main functions of factory smoke vent skylight are daylighting, smoke exhaust and ventilation. Before selecting and designing automatic smoke vent, various factors need to be considered in order to design and produce smoke vents which meet specifications. From a technical perspective, the factors that need to be considered in the design smoke vent system.

1. Calculation of ventilation volume of smoke vent skylight

The ventilation volume must be calculated by scientific parameters, and the throat size and model should be designed according to the temperature difference between the inlet and exhaust air of the automatic roof vents. Then according to the ventilation volume per square meter of the smoke vents, calculate the total ventilation smoke exhaust volume, and then determine the total length of the smoke vent skylight. 

2. Selection of profiles for automatic smoke vent

Different types of electric roof smoke vent use different profiles, for example, the main profiles of triangular electric daylighting skylights are FRP daylighting panels and aluminum alloy profiles; the main profiles of streamlined continuous rooflights are composed of outer guards, skeletons, and rain panels. Among them, the outer guard plate is pressed from aluminum-zinc profile.

3. Applicability of roof smoke vent

The industry has a high degree of industry segmentation, and different types of factory roof daylighting skylights are applicable to different industries. For example, warehousing, logistics, e-commerce and other industries have less demand for ventilation and smoke exhaust. You can install in-line electric daylighting skylights, triangular daylighting skylights or streamlined ventilators with small throats; forging, steelmaking, chemical, heavy industry Contour industries have a greater demand for ventilation and smoke exhaust. Such high-temperature and high-heat industries are suitable for installing streamlined continuous rooflights.
