3.6.2 Terminal Device Data

Terminal Type
Applicability All HVAC zones
Definition

A terminal unit includes any device serving a zone (or group of zones collected in a thermal block) that has the ability to reheat or recool in response to the zone thermostat. This includes:

  • None (the case for single zone units)
  • VAV box
  • Series Fan-Powered VAV  box
  • Parallel Fan-Powered VAV box
  • Induction-type VAV box
  • Dual-duct mixing box (constant volume and VAV)
  • Two and three duct mixing dampers (multi-zone systems)
  • Reheat coil (constant volume systems)
  • Perimeter induction units
Units List (see above)
