The ridge ventilator can realize the ventilation and smoke exhaust of the workshop and provide fresh air for the workshop. As factory owners pay more and more attention to the first-line production environment, more and more industrial plants will choose to install smoke vent rooflight.

1. The ventilation dynamics principle of the ridge ventilator

According to the principles of physics, the wind pressure difference formed by the action of wind can realize the circulation of air. The smoke vents are installed on the roof of the factory building. The windward side of the factory building is determined by the overall building of the factory building and the local wind direction. In the case of ventilation, the dominant wind direction of the factory building is the windward side. When the wind blows to the factory building, the factory building has a blocking effect on the wind, generating a positive pressure under the action of the windward side, and forming a negative pressure on the side of the building factory building. The pressure difference between the two creates ventilation.

2. Ventilation principle of smoke vent rooflight

The principle of the steel roof ridge vent is to use the temperature difference between the inside and outside of the workshop to form a thermal difference, thereby realizing natural ventilation, using the principle of rising hot air to discharge the smoke and exhaust gas generated during the production and operation of the workshop, and the fresh air outside the workshop is sucked in to achieve the purpose of ventilation.

3. Analysis of ventilation and smoke exhaust efficiency of smoke vents

The ventilation and smoke exhaust efficiency of the ridge ventilator directly affects the air quality of the workshop, and the main factors that affect the smoke exhaust and ventilation efficiency of the smoke vents are related to the thermal pressure difference, the exhaust outlet, and the size of the throat. First of all, from the perspective of environmental factors, the greater the thermal difference between the exhaust vents, the more obvious the effect of thermal pressure, and the better the ventilation and smoke exhaust effect; secondly, from the perspective of the roof ventilator itself, the larger the throat size of the ventilator, The better the ventilation efficiency.
