Information

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

Correct replacement of the replaceable submodels and, thus, flexible aggregation to a new model approach is demonstrated.

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

Revisions

  • May 23, 2025, by Michael Wetter:
    Changed nominal temperature during reverse mode so that heat pump has a positive lift.
    This is for IBPSA, #2013.
  • 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.
  • May 2, 2024, by Michael Wetter:
    Refactored check for device identifiers.
    This is for IBPSA, #1576.
  • October 2, 2022 by Fabian Wuellhorst:
    First implementation (see issue #1576)
