Grey-box model for reversible and non-reversible chillers
Extends from BuildingSystems.Fluid.HeatPumps.ModularReversible.BaseClasses.PartialReversibleRefrigerantMachine.
Information
Model of a reversible, modular chiller. 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 (
BuildingSystems.Fluid.HeatPumps.ModularReversible.BaseClasses.PartialReversibleRefrigerantMachine),
this model has the coo signal to choose
the operation mode of the chiller.
For more information, see BuildingSystems.Fluid.HeatPumps.ModularReversible.UsersGuide.
