modelLookUpTableND
N-dimensional table with data for heat pump
Extends from AixLib.Obsolete.Year2024.DataBase.HeatPump.PerformanceData.BaseClasses.PartialPerformanceData.
Information
Basic models showing the concept of using n-dimensional table data for the innerCycle of the heat pump model. This model assumes one provides data for inverter controlled heat pumps or chillers. However, this basis structure can be used to create own models, where electrical power and condenser depend on other inputs, such as ambient temperature.
