.AixLib.Obsolete.Year2024.DataBase.HeatPump.Functions.IcingFactor.PartialBaseFct

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.
