Extends from Buildings.Fluid.HeatPumps.ModularReversible.RefrigerantCycle.BaseClasses.PartialHeatPumpCycle (Partial model to allow selection of only heat pump options).

Information

This model serves as a wrapper class to integrate the block Buildings.Fluid.HeatPumps.ModularReversible.RefrigerantCycle.BaseClasses.TableData2DLoadDep into heat pump models. For a complete description of all modeling assumptions, please refer to the documentation of this block.
