Abstract
This Paper is the Outline of Experimental Study on Room Pressure Fluctuation Factor in Steady Conditions at Pressure Controlled Room by Pressure Control Damper(PCD).The Results are following that, 1)Ductwork with Straightduct in the Upstream and the Downstream of the PCD was Preferable. 2)When the Ratio of Air Leakage and Supply Air Volume(Air Leakage Ratio) was Small, the Large Fluctuations was Caused. 3)Operating PCD Gradually is Effective for the Pressure Fluctuation Factor in Steady Conditions.
