With a larger room area, there is a greater volume of air that needs to be exchanged to maintain suitable air quality and comfort levels. Thus, the proportional expansion in exhaust flow rate aligns with the increased ventilation demand associated with larger spaces. This insight emphasizes the importance of considering spatial dimensions when designing ventilation systems to ensure effective air circulation and quality throughout the sports hall. The third study investigated the variation of the duct area in relation to the exhaust flow passing through it. By altering the duct dimensions, researchers aimed to optimize airflow dynamics and minimize resistance, thereby enhancing the overall efficiency of the ventilation system. As the flow in the room increased from 1500 to 2500 L/s, the duct area similarly increased from 0.2 m² to 0.43 m². This finding underscores the direct relationship between the size of the enclosed space and the duct dimensions required for efficient ventilation (Figure 3-20). efficient ventilation (Figure 3-20). 0.5 Area of Duct in m^2 Flow in each Room 0.4 0.3 0.2 0.1 0 1500 1700 1900 2100 2300 2500 Exshuast Air in Each Room Area of Duct in m^2 Figure 3-20 Variation of the area of Duct m^2 as function flow exhaust With a larger room area, a proportionally larger duct area is necessary to accommodate the increased airflow and ensure optimal air distribution throughout the hall. Thus, the proportional expansion in duct area aligns with the ventilation demands associated with larger spaces, highlighting the importance of appropriately sizing ductwork to facilitate effective air exchange and distribution in ventilation systems. The final parametric study demonstrated a proportional relationship between the length of the duct and the corresponding pressure drop. As the length of the duct increased from 10 to 50 meters, the pressure drops similarly increased from 36.6 Pa to 83 Pa as in Figure 3-21.
