What is the throat of the door-hinged louver air vent?

    Door-hinged louver air vents are a common ventilation device that is commonly used in doors, windows, ventilation ducts, and air handling systems of buildings. The throat is an important part of the door hinge louver air outlet. The throat refers to the air inlet or outlet of the door-hinged louver air vent, through which air can enter or leave the interior of the building. The design structure of the throat usually uses openable and closable louvers, which can be adjusted as needed to control the flow and direction of air.

    On the roofs of buildings in industrial parks, rectangular, circular, or spherical natural ventilators are installed, including door-hinged louver air vents. The ventilation effect of the ventilator determines the quality of the production environment in factories and workshops, and the ventilation effect of the ventilator largely depends on the size of its throat. So what does throat size refer to?

    As a type of natural ventilator, hinged louver vents will be left on the roof panel for ventilation before the construction of the new steel structure industrial factory is completed. The throat size of the ventilator refers to the reserved size of the roof panel hole, which is approximately equal to the ventilation area. Generally, the air outlet parameters given in the design are throat size. Assuming that other factors that affect the ventilation effect remain unchanged, the larger the throat size, the greater the ventilation volume, and the better the ventilation effect.

    The throat in the door-hinged louver air vent has many important functions. First of all, it can adjust the exchange volume of indoor and outdoor air, help maintain the circulation of indoor fresh air, improve indoor air quality, and provide a healthy and comfortable working or living environment. Secondly, the throat can also effectively control the direction of the air, avoid unnecessary airflow interference, and improve the ventilation effect. In addition, the opening and closing angle of the throat can be adjusted according to seasons and climate conditions to adapt to different outside temperatures and humidity.
