functionPartialBaseFct
Base function for all icing factor functions
Extends from Modelica.Icons.Function, AixLib.Obsolete.BaseClasses.ObsoleteModel.
Information
Base function for calculation of the icing factor. The normalized value represents reduction of heat exchange as a result of icing of the evaporator.
iceFac: Efficiency factor (0..1) to estimate influence of icing. 0 means no heat is transferred through heat exchanger (fully frozen); 1 means no icing/frosting.
