Calculating heat pump data based on a polynomal approach
Extends from AixLib.Obsolete.Year2024.DataBase.HeatPump.PerformanceData.BaseClasses.PartialPerformanceData (Model with a replaceable for different methods of data aggregation).
Information
This model is used to calculate the three values based on a functional approach. The user can choose between several functions or use their own.
As the base function only returns the electrical power and the condenser heat flow, the evaporator heat flow is calculated with the following energy balance:
QEva = QCon - P_el
