SynC · Topic
These are the standards in the SynC Standards library that cover VAV Boxes. Each one is a complete, plain-language specification: the scope it applies to, the requirements that govern it, and a structured equipment datasheet listing the values a project has to decide — ratings, materials, setpoints, and the standards each is verified against. All of it is free to read without an account and published under CC BY-SA 4.0.
A standard usually carries several topics, so most of the entries below also appear under neighbouring subjects. The topics each one carries are listed on its own page.
Factory-fabricated air terminal units that meter primary air from a central air system into an individual thermal zone in commercial, institutional, healthcare, and industrial buildings. Covers single-duct, dual-duct, and bypass metering arrangements; variable-volume and constant-volume airflow control; pressure-independent and pressure-dependent control basis; parallel and series fan sections; hot water, steam, and electric reheat with their valves, actuators, and safety devices; casing construction and acoustic treatment; primary damper and actuator; primary airflow sensing; radiated and discharge sound; the zone controller, zone sensor, and building automation interface; factory testing; installation; and field airflow, functional, and acoustic verification.
