Systems in this type of building
- Air handling unit (AHU) · blows air across the chilled-water coil and into the building
- Fan motor + VSD · varies the fan speed with demand instead of running flat out
- Cooling coil · chilled water in, cooled and dried air out
- Supply duct · carries conditioned air to the rooms
- Ceiling diffusers · spread the supply air across the room
- Return air · room air goes back to the AHU to be cooled again
- Room sensor · temperature or CO₂ reading that tells the AHU how hard to work
- Anemometer · air speed at the diffusers, to check the airflow: UNI-T UT363
