.Buildings.Controls.OBC.ASHRAE.G36.AHUs.MultiZone.VAV.SetPoints.SupplySignals .Buildings.Controls.OBC.ASHRAE.G36.AHUs.MultiZone.VAV.SetPoints.SupplySignalsBlock that outputs the supply temperature control loop signal, and the coil valve postions for VAV system with multiple zones, implemented according to Section 5.16.2.3 of the ASHRAE Guideline G36, May 2020.
The supply air temperature control loop signal
uTSup is computed using a PI controller that tracks
the supply air temperature setpoint TSupSet. If the
fan is off, then uTSup = 0.
Heating valve control signal (or modulating electric heating
coil if applicable) yHeaCoi and cooling valve control
signal yCooCoi are sequenced based on the supply air
temperature control loop signal uTSup. From
uTSup = uHea_max to uTSup = -1,
yHeaCoi increases linearly from 0 to 1.
Similarly, uTSup = uCoo_min to uTSup =
+1, yCooCoi increases linearly from 0 to
1.
The output uTSup can be used in a controller for
the economizer.
