Airflow in ducts refers to the movement of air through a system of tubes or channels, commonly found in heating, ventilation, and air conditioning (HVAC) systems. This airflow is essential for distributing conditioned air throughout a building, ensuring comfort and maintaining indoor air quality. The design of the ductwork, including its size and shape, affects how efficiently air flows. Properly sized ducts minimize resistance and allow for balanced airflow, which helps in achieving consistent temperatures in different rooms. Regular maintenance, such as cleaning and sealing, can also improve airflow and system performance.
