Validation model for heat pump group
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 components are exposed to a constant differential pressure and a varying return temperature.
The model is configured to represent either a non-reversible heat pump
(component hpAwNrv) or a reversible heat pump
(component hpAw) that switches between cooling and heating
mode.
