This is a model for a water-to-water heat pump where the capacity
and input power are computed based on the equation fit method.
The model can be configured with the parameter is_rev
to represent either a non-reversible heat pump (heating only) or a
reversible heat pump.
This model uses
Buildings.Fluid.HeatPumps.EquationFitReversible,
which the user may refer to for the modeling assumptions.
Refer to the documentation of the interface class Buildings.Templates.Components.Interfaces.PartialHeatPumpEquationFit for a description of the available control input and output variables.
