Core Methods and Practical Guidelines for Airflow Calculation in HVAC Ducts

Airflow calculation in HVAC ducts is a core in the design and operation of ventilation systems, whose basic principle is to calculate the volume of air passing through a specific cross-section of the duct per unit time. The core formula for calculation is: Airflow (Q) = Cross-sectional Area (A) × Average Air Velocity (V). Among them, the unit of airflow (Q) is usually cubic meters per...
