HVAC air balancing is really a commissioning method that involves the adjustment of dampers while in the ductwork plus the good-tuning with the airflow at Every diffuser and grille to make sure that all diffusers and grilles have equivalent and well balanced airflow.
If you’re handling new HVAC models, your drawing really should now point out the initial airflow. Or else, more info suggest the designed airflow with your drawing.
