modelHeatPumpGroupAirToWaterPolyvalent
Validation model for AWHP group with polyvalent HP
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model validates the model Buildings.Templates.Plants.HeatPumps.Components.HeatPumpGroups.AirToWater in a configuration in which the heat pump group components are exposed to a constant differential pressure and a varying return temperature.
The model is configured to represent either a single polyvalent HP without
reversible heat pumps (component php) or a group of reversible
heat pumps with a single polyvalent HP (component hpPhp).
