Before installing low-profile ventilator, there are many factors that need to be considered, including the type of ventilation skylights, technical parameters, specifications, profiles, and performance technologies. Performance technologies include smoke exhaust ventilation performance, lighting performance, and windproof performance. The most important thing, then, let's focus on the analysis of windproof performance.
1. Influencing factors of low-profile ventilator
Because one of the factors affecting the windproof performance of the thin roof skylight is the geographical area. Since the project sites are all over the country, different regions have different requirements for the windproof performance. For example, there are many strong winds, typhoons and hurricanes in the southeastern coastal areas, and the rainproof performance of the ventilation skylights is relatively high. The thin roof skylights must have good wind resistance performance, reduce the overall center of gravity of the ventilator, and reduce the wind resistance caused by the windy weather to the ventilator. pressure.
2. Classification of natural ventilator
Natural ventilator is mainly divided into thin ventilation buildings (parallel air duct type) and thin ventilation air buildings (interval air duct type), which have low height, low load, low steel consumption, and good windproof performance. For some areas with high requirements for windproof performance, it is not recommended to install large-throat streamlined ventilators. Due to the high height and large wind resistance, collapse accidents will occur in areas with strong winds, which will cause greater damage to the normal operation of the plant. Security risks.
3. Design of Type 11 thin smoke vent
The windproof performance of the 11-type thin smoke vent is designed according to the CAD drawings, and before designing the CAD drawings, it is necessary to carry out scientific calculation in combination with the actual situation of the project site, including wind, wind pressure, rainfall, temperature and humidity and other aspects.
