functionpartialIcingFactor

Base function for all icing factor functions

Extends from Modelica.Icons.Function (Icon for functions).

Information

Base function for calculation of the icing factor iceFac. It represents the reduction of heat exchange as a result of icing of the evaporator.

This function is used in the model Buildings.Fluid.HeatPumps.ModularReversible.RefrigerantCycle.Frosting.FunctionalIcingFactor.

Typically, functions should only require evaporator side data for calculation of the iceFac.

For more information on the iceFac, see the documentation of Buildings.Fluid.HeatPumps.ModularReversible.RefrigerantCycle.BaseClasses.PartialRefrigerantCycle

Inputs

Modelica.Units.SI.MassFlowRatemEva_flowMass flow rate at the evaporator

Outputs

TypeNameDefaultDescription
RealiceFacIcing factor (0: no heat transfer; 1: no effect)
