Buildings.Examples.ScalableBenchmarks.BuildingVAV.BaseClasses.ControlBus

Control bus that is adapted to the signals connected to it

Information

This connector defines the expandable connector ControlBus that is used to connect control signals. Note, this connector is empty. When using it, the actual content is constructed by the signals connected to this bus.

Extends from Modelica.Icons.SignalBus (Icon for signal bus).

Buildings.Examples.ScalableBenchmarks.BuildingVAV.BaseClasses.FanOnOffWithDP

Controller for fan on/off and to provide prescribed dP

Information

This model outputs ON/OFF signal to control fan operation. When the system is in mode like unoccupiedOff, safety, it outputs false so that fan should be OFF and provide 0 pressure rise; When the system is in mode like unoccupiedNightSetBack,occupied,unoccupiedWarmUp, unoccupiedPreCool, it outputs true so that fan should be ON and provide preRis pressure rise.

Buildings.Examples.ScalableBenchmarks.BuildingVAV.BaseClasses.VAVBranch

Supply branch of a VAV system

Information

Model for a VAV supply branch. The terminal VAV box has a pressure independent damper and a water reheat coil. The pressure independent damper model includes an idealized flow rate controller and requires a discharge air flow rate set-point (normalized to the nominal value) as a control signal.
