Overview: The control of air flow rate in VAV systems is important for several reasons, including acoustics, ventilation, energy management and occupant comfort. Most VAV terminals today are supplied with pressure independent controllers of some type (pneumatic, analog electronic and digital electronic), and all require an inlet flow sensor supplied by the VAV box manufacturer. Indeed, upcoming revisions to ASHRAE Standard 62 will likely require pressure independent controls to assure minimum ventilation rates in spaces. This paper discusses many aspects regarding inlet sensing of VAV terminals.
