The working principle of the roof vents is to use the wind pressure difference and the thermal pressure difference to remove the waste heat, smoke and exhaust gas generated by the production activities of the factory building, and to inhale fresh air to achieve the purpose of smoke exhaust and ventilation. Smoke ventilation is widely used in metallurgy, ironmaking, manufacturing, chemical, electric power, shipbuilding, machinery, logistics, warehousing and other industries. So how should an industrial plant choose the smoke vents type?

1. Essential elements for the selection of roof vents

Generally speaking, factors that need to be considered before installing smoke ventilator in industrial plants include ventilation, waterproofness, structural safety, and load. We need to first consider the overall load of the roof smoke vent before installing it. Low-profile ventilator is recommended to clients, which has low height, light weight, small load on the roof, and wind resistance. Compared with large-scale high-capacity natural ventilation skylights, its structure consumes less steel, which can reduce the total investment cost of business owners.

2. Calculation of ventilation volume of roof mounted vents

From the theoretical formula of the roof smoke vent skylights, according to the formula Q=V F, the ventilation volume is the product of the wind speed and the cross-sectional area of ​​the air duct, and the ventilation volume can be calculated. From the perspective of the windproofness of the smoke exhaust and ventilation skylights, before installing smoke ventilator, it is necessary to conduct a survey of regional related parameters, especially in windy areas, and the

windproof performance needs to be considered.

3. Choose smoke exhaust ventilator according to the actual situation of the plant

The installation of smoke vent windows in the plant should be selected according to the actual situation, including the building structure of the plant, roof panels, and throat size. In order to realize large-area ventilation in the factory building, it is necessary to install smoke vent skylights with ventilation as the main and daylighting as supplementary.
