Electrically operated ventilation skylights are based on natural open ventilation skylights with the addition of an electric system and opening/closing flaps. When ventilation, air exchange, smoke exhaust, and dust removal are needed, the electrically operated flaps are opened. When ventilation and smoke exhaust are not required, the electric flaps remain closed to prevent indoor and outdoor air convection.
Ventilation and daylighting skylights are high in strength and lightweight. The density of hot-dip galvanized steel pipes is approximately 2.70, compared to the density of steel at 7.85. This reduces the load-bearing capacity required for the workshop floor, making the foundation relatively easier to optimize. It significantly saves on the amount of structural steel used, conserves material resources, avoids unnecessary waste, and reduces cost consumption.
According to the national standard atlas, the primary function of smoke exhaust skylights is daylighting, with smoke exhaust as a secondary function. To prevent damage to the skylight and loss of property inside the factory due to untimely closure, smoke exhaust skylights need to have fire alarm linkage functionality. They should also be equipped with auxiliary monitoring tools such as rain sensors, wind sensors, and smoke sensors to ensure automatic opening and closing of the skylight under windy and rainy conditions.
Smoke exhaust skylights are categorized into three types based on their external shape: linear, triangular, and arched. Arched side-opening smoke exhaust skylights can remain open during windy and rainy weather. In contrast, linear and triangular smoke exhaust skylights must be closed promptly in such conditions due to their structural design.
