Buildings.ThermalZones.ReducedOrder.Validation

Collection of validation models

Information

This package contains models for validation of Reduced Order Models. The examples plot various outputs, which have been verified against comparative results. These model outputs are stored as reference data to allow continuous validation whenever models in the library change.

Extends from Modelica.Icons.ExamplesPackage (Icon for packages containing runnable examples).

Buildings.ThermalZones.ReducedOrder.Validation.RoomSteadyState

Validation model that checks whether all weather data is set to a constant

Buildings.ThermalZones.ReducedOrder.Validation.RoomSteadyState

Information

This model validates that the RC network model starts at and remains at exactly 20°C if there is no solar radiation and constant outdoor conditions.

Extends from ThermalZones.ReducedOrder.Examples.SimpleRoomOneElement (Illustrates the use of a thermal zone with one heat conduction element).
