Heating Ventilation and Air Conditioning system are installed in offshore production facilities, marine vessels and buildings to create a comfortable and efficient indoor environment. Recently, as ships and buildings become larger, more precise control of the air volume supplied to each indoor space is required. Generally, the air volume is controlled by the volume control dampers that make up the duct system, therefore it is necessary to improve the airflow control function of the damper. In this study, we suggested new type of blade to improve the air volume control at the circular volume control dampers. In consideration of the control and the operation, we designed a blade shape to control the flow rate more precisely and calculated the pressure loss by computational fluid dynamics, and tested the result with a prototype damper under the same flow rate and the attack of angle of the blade. The prototype damper has outperformed the conventional damper.
