modelLargeScaleWaterToWater_OneRoomRadiator
Extends from Modelica.Icons.Example (Icon for runnable examples), Buildings.Fluid.HeatPumps.ModularReversible.Examples.BaseClasses.PartialOneRoomRadiator (Simple room model with radiator, without a heat pump).
Information
This example demonstrates how to use the Buildings.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 Buildings.Fluid.HeatPumps.ModularReversible.Examples.BaseClasses.PartialOneRoomRadiator for further information on the example.
