Selecting the inlet size of a variable air volume (VAV) terminal box requires the consideration of five factors: (1) pressure drop across the box; (2) ability of the VAV box controller to measure and control the desired minimum and maximum airflow setpoints; (3) first costs of the VAV box, its installation, and controls; (4) noise generation; and (5) space constraints.
