functionpartialIcingFactor
Base function for all icing factor functions
Extends from Modelica.Icons.Function.
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.ThermodynamicTemperature | TEvaOutMea | Evaporator return temperature | |
| Modelica.Units.SI.MassFlowRate | mEva_flow | Mass flow rate at the evaporator |
Outputs
| Type | Name | Default | Description |
|---|---|---|---|
| Real | iceFac | Icing factor (0: no heat transfer; 1: no effect) |
