…A VAV box is the unit that controls the flow of air. The single duct terminal configuration is the simplest, where a VAV box is connected to a single supply air duct that delivers treated air from an air-handling unit (AHU) to the space the box is serving. This configuration can deliver air at variable temperatures…
