Buildings.Controls.OBC.RadiantSystems.Cooling.Validation

Collection of validation models

Information

This package contains validation models for the classes in Buildings.Controls.OBC.RadiantSystems.Cooling.

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.

HighMassSupplyTemperature_TRoomRelHum	Validation model for the room temperature controller

Buildings.Controls.OBC.RadiantSystems.Cooling.Validation.HighMassSupplyTemperature_TRoomRelHum

Validation model for the room temperature controller

Buildings.Controls.OBC.RadiantSystems.Cooling.Validation.HighMassSupplyTemperature_TRoomRelHum

Information

This example validates the room temperature controller Buildings.Controls.OBC.RadiantSystems.Cooling.HighMassSupplyTemperature_TRoomRelHum for the radiant system. The validation model applies a ramp signal to the controller input for the measured room air temperature. The model also calculates the dew point temperature to verify that the supply water temperature is never below the dew point.
