For southeast coastal cities, when factories install smoke ventilator, they need to consider the particularity of multiple typhoons, heavy rains, and heavy rainfall in the region. Among them, the windproof performance of the smoke exhaust ventilator is very important. As a smoke vent supplier, Mcwell will give you analysis of the windproof technical performance of smoke vents.

Firstly, from the perspective of the theoretical structure of the electric smoke ventilator of the factory building, the windproof performance mainly refers to the ratio of the pressure (or suction) formed by the wind on the structural surface of the smoke hatch skylight and the theoretical wind pressure calculated according to the incoming wind speed. The ratio is aerodynamic coefficient. Generally speaking, the coefficient can reflect the stable wind pressure distribution on the surface of the smoke vent. The specific distribution form depends on the shape, size, enclosure, shielding condition and airflow direction of the roof vents.

Secondly, according to the wind carrier type coefficient of smoke vent rooflight, it can be concluded that the windward side is pressure, the leeward and downwind sides are suction, and the top surface is mainly affected by the slope angle, which may be pressure or suction.

For coastal areas with many typhoons, low-profile ventilator are often installed because of their low height, low wind resistance coefficient and good wind resistance. Under the premise of low load, natural ventilation and smoke exhaust can be better realized.
