modelLargeScaleWaterToWater_OneRoomRadiator

Large scale water to water heat pump connected to a simple room model with radiator

Extends from Modelica.Icons.Example, AixLib.Fluid.HeatPumps.ModularReversible.Examples.BaseClasses.PartialOneRoomRadiator.

Information

This example demonstrates how to use the AixLib.Fluid.HeatPumps.ModularReversible.LargeScaleWaterToWater heat pump model. Please check the associated documentation for further information.

Contrary to the other models, parameters for heat exchanger inertia (tau) and mass flow rates are calculated automatically based on the heat demand.

Furthermore, this example demonstrates the warnings which are raised if two devices are combined with different sizes, leading to different scaling factors for heating and cooling operation. If the default QCoo_flow_nominal is used (leading to the same scaling factors), the mass flow rates will differ. Setting the parameter allowDifferentDeviceIdentifiers to false, an additional warning is raised, indicating that the table data for cooling and heating operation do not originate from the same real device.

Please check the documentation of AixLib.Fluid.HeatPumps.ModularReversible.Examples.BaseClasses.PartialOneRoomRadiator for further information on the example.

Revisions

  • March 7, 2025, by Michael Wetter:
    Introduced medium MediumEva and refactored medium assignment as the model replaced non-replaceable medium bindings.
    This is for #1981.
  • October 2, 2022 by Fabian Wuellhorst:
    First implementation (see issue #1576)
