modelTableData2DLoadDep
Validation model for heat pump component with ideal controls
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This model illustrates the use of Buildings.Fluid.HeatPumps.ModularReversible.TableData2DLoadDep in a configuration in which water-to-water heat pump components are exposed to a constant differential pressure and a varying return temperature on the load side.
The heat pump components are configured to represent either a non-reversible
heat pump (component hpNrv) or a reversible heat pump
(component hp) that switches between cooling and heating mode.
