Grey-box model for reversible and non-reversible heat pumps
Extends from AixLib.Fluid.HeatPumps.ModularReversible.BaseClasses.PartialReversibleRefrigerantMachine.
Information
Model of a reversible, modular heat pump. This models allows combining any of the available modules for refrigerant heating or cooling cycles, inertias, heat losses, and safety controls. All features are optional.
Adding to the partial model (
AixLib.Fluid.HeatPumps.ModularReversible.BaseClasses.PartialReversibleRefrigerantMachine),
this model has the hea signal to choose
the operation mode of the heat pump.
For more information on the approach, see AixLib.Fluid.HeatPumps.ModularReversible.UsersGuide.
