In industrial plants, some plants have a slightly higher demand for daylighting than ventilation, and they will choose a smoke ventilation system that can both daylight and ventilate. Natural ventilation system can bring good lighting and a comfortable ventilation environment to the interior. The role of natural roof ventilation in industrial plants cannot be ignored. Smoke ventilation system is suitable for buildings with daylighting as the mainstay and ventilation as a supplement. When the smoke vents are fully opened, the smoke exhaust is the largest, and the maximum opening angle of the in-line skylight is 90°. The top of the smoke vent rooflight is parallel to the installation surface, and the wind resistance coefficient is small. The airtightness, watertightness, and wind pressure resistance of the ventilating and daylighting skylights meet the requirements of GB/T7106-2008, and the daylighting performance meets the requirements of GB/T11976-2002. The role of smoke ventilation system is to effectively exhaust indoor heat and humidity, creating an extremely comfortable working environment for us, improving the work efficiency of employees, and creating greater economic benefits for the enterprise.
