functionPartialBaseFct

Base function for all icing factor functions

Extends from Modelica.Icons.Function (Icon for functions), AixLib.Obsolete.BaseClasses.ObsoleteModel (Icon for classes that are obsolete and will be removed in later versions).

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.
