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
| Type | Name | Default | Description |
|---|---|---|---|

| 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) |
