modelSingleZoneVAVSupply_u
Scatter plots for control signal of a single zone VAV controller from ASHRAE Guideline 36
Extends from Modelica.Icons.Example.
Information
This example demonstrates how to create a scatter plot that shows
for a single zone VAV control logic
the heating and cooling set point temperatures, and the fan speed,
all as a function of the heating and cooling control signal.
The sequence that will be used to plot the sequence diagram is
Buildings.Controls.OBC.ASHRAE.G36.AHUs.SingleZone.VAV.SetPoints.Supply
and shown below.
The plot will be generated in the file plots.html.
