Experimental study on flowing characteristics of uniform ventilation duct component

Proposes a new uniform ventilation duct component. In order to investigate the flowing characteristic and the uniformity of air supply, applies the new duct component to the experimental platform. The experimental results show that the unbalance rate maintains below 5% when the fan is running between 10 and 50 Hz, resulting in uniformity of air supply. It can remarkably reduce the cost of adjustment in condition that such design form of component is applied to the actual long duct air conditioning system.
