modelChillersCompression
Validation model for compression chiller component
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model validates the model Buildings.Templates.Components.Chillers.Compression in a configuration in which the chiller is exposed to the design CHW differential pressure and a varying CHW return temperature.
The chiller model is configured to represent either an air-cooled
chiller (component chiAirCoo) or a water-cooled
chiller (component chiWatCoo).
