AIR FLOW IN AN INDUSTRIAL VENTILATION SYSTEM

Abstract

Ventilation devices are produced in large quantities therefore it is desirable to reduce the power consumption of their damper actuators. The electric power consumed by the actuators depends on the size of the damper and to some extent on the pressure generated by the air stream flowing through the ventilation ducts. The air pressure mainly depends on the air flow rate inside the duct and varies with changes in the damper angle settings. The article presents the results of air flow simulations in a ventilation duct and the resulting torque acting on a damper installed symmetrically in relation to the axis of the air duct.<br/><br/>
