functionBasicIcingApproach

A function which utilizes the outdoor air temperature and current heat flow from the evaporator

Extends from PartialBaseFct (Base function for all icing factor functions).

Information

This function can be used to implement a simple icing approach, e.g. based on outdoor air temperature or time based.

Inputs

TypeNameDefaultDescription
Modelica.Units.SI.ThermodynamicTemperatureT_flow_ev (from PartialBaseFct)Evaporator supply temperature
Modelica.Units.SI.ThermodynamicTemperatureT_ret_ev (from PartialBaseFct)Evaporator return temperature
Modelica.Units.SI.ThermodynamicTemperatureT_oda (from PartialBaseFct)Outdoor air temperature
Modelica.Units.SI.MassFlowRatem_flow_ev (from PartialBaseFct)Mass flow rate at the evaporator

Outputs

TypeNameDefaultDescription
RealiceFac (from PartialBaseFct)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.
