modelPartialInnerCycle
Blackbox model of refrigerant cycle of a vapour compression machine (heat pump or chiller)
Information
This black box model represents the refrigerant cycle of a vapour compression machine. Used in AixLib.Obsolete.Year2024.Fluid.HeatPumps.HeatPump and AixLib.Fluid.Chiller.Chiller, this model serves the simulation of a reversible vapour compression machine. Thus, data both of chillers and heat pumps can be used to calculate the three relevant values P_el, QCon and QEva. The mode of the machine is used to switch between the performance data of the chiller and the heat pump.
The user can choose between different types of performance data or implement a new black-box model by extending from the partial model.
- LookUpTable2D: Use 2D-data based on the DIN EN 14511
- LookUpTableND: Use SDF-data tables to model invertercontroller heat pumps or chillers or include other dependencies (ambient temperature etc.)
- PolynomalApproach: Use a function based approach to calculate the ouputs. Different functions are already implemented.
