As a professional smoke vents manufacturer, Mcwell will introduce the working principle of natural roof ventilation.

According to the position of the natural roof ventilation, the natural ventilation system can be divided into two types: horizontal and vertical. According to whether the ridge ventilator has a valve plate or not, it can be divided into two types: open-closing type and opening type. Among them, opening and closing smoke vents also have three forms: electric type, manual type and fire-fighting linkage type.

According to the shape of the natural vent, there are also roof louver vent and arched continuous rooflight. The surface treatment of smoke vents also includes galvanizing, painting and other treatment methods, which bring different anti-corrosion effects to the ventilating skylights.

The working principle of the ventilation skylight is to ventilate according to the temperature difference between indoor and outdoor. Generally indoors are relatively warm, especially in many workshops because there are a lot of mechanical equipment in operation, and many workshops use heating equipment, so the temperature difference with the outdoor temperature is relatively large. The density of high-temperature gas is relatively low, so it will continue to rise and eventually be exhausted by the ventilating skylight. So at this time, the indoor air pressure is relatively small, so the outdoor air will compensate for the indoor air, thus completing the ventilation.
