Roof natural ventilatorsIt is a kind of equipment that uses natural wind power to achieve ventilation and air exchange, and it has been widely used in many fields such as industrial plants and large public buildings with its characteristics of energy saving, environmental protection and high efficiency.
Choosing the right roof ventilator is crucial, as improper sizing can lead to unsatisfactory ventilation and the desired design results. Therefore, when choosing a roof natural ventilator, the following three principles should be followed:
First, the principle of ventilation
The selection of ventilators must be based on detailed natural ventilation design calculations and work closely with the steel frame to achieve a rational layout that can meet the needs of ventilation. For example, in places where a large amount of harmful gases need to be emitted, one with sufficient exhaust air volume should be selectedOpen ventilatorsto ensure effective removal of contaminants.
Second, the principle of temperature difference
In workshops that generate a large amount of waste heat, such as boiler rooms, ventilation mainly depends on the thermal pressure difference caused by the temperature difference between indoor and outdoor air. In these environments where temperature differences are large, choosing a streamlined ventilator can make more efficient use of the temperature difference to enhance ventilation. For example, in the boiler room, several groups can be installedStreamlined downhill ventilatorto significantly improve ventilation efficiency.
3. The principle of air pressure
In the case that it is necessary to use both the thermal pressure difference and the wind pressure difference, that is, when the indoor and outdoor temperature difference is small, and the outdoor average wind speed is large, the choice is selectedThin ventilatorsMore appropriate. This ventilator is designed to use wind energy more efficiently for ventilation and is ideal for such occasions. For example, for warehouses located in coastal areas, the installation of thin ventilators can improve ventilation efficiency.
Following the above three-type principle, the normal operation of the natural roof ventilator can be ensured, and the satisfactory ventilation effect can be achieved, so as to improve the indoor comfort and environmental quality of the building.
