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
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Units.SI.ThermodynamicTemperature | T_flow_ev (from PartialBaseFct) | Evaporator supply temperature | |
| Modelica.Units.SI.ThermodynamicTemperature | T_ret_ev (from PartialBaseFct) | Evaporator return temperature | |
| Modelica.Units.SI.ThermodynamicTemperature | T_oda (from PartialBaseFct) | Outdoor air temperature | |
| Modelica.Units.SI.MassFlowRate | m_flow_ev (from PartialBaseFct) | Mass flow rate at the evaporator |
Outputs
| Type | Name | Default | Description |
|---|---|---|---|
| Real | iceFac (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. |
