Collection of validation models
Information
This package contains validation models for the classes in
Buildings.Controls.OBC.ASHRAE.G36_PR1.AHUs.SingleZone.SetPoints.
Note that most validation models contain simple input data
which may not be realistic, but for which the correct
output can be obtained through an analytic solution.
The examples plot various outputs, which have been verified against these
solutions. These model outputs are stored as reference data and
used for continuous validation whenever models in the library change.

Validation model for outdoor minus room air temperature
Information
This example validates
Buildings.Controls.OBC.ASHRAE.G36_PR1.AHUs.SingleZone.SetPoints.VAVSupply
for a change in temperature difference between zone air and outdoor air.
Hence, this model validates whether the adjustment of the fan speed for medium
cooling load is correct implemented.

Validation model for control input
Information
This example validates
Buildings.Controls.OBC.ASHRAE.G36_PR1.AHUs.SingleZone.SetPoints.VAVSupply
for different control signals.
Each controller is configured identical, but the input signal for TZon differs
in order to validate that the fan speed is increased correctly.
