modelIcingBlock
Block which decreases evaporator power by an icing factor
Extends from AixLib.Obsolete.BaseClasses.ObsoleteModel.
Information
Model for calculation of the icing factor. The replaceable function uses the inputs to calculate the resulting icing factor.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Integer | hourDay | 16 | Hour of the day |
| AixLib.Utilities.Time.Types.ZeroTime | zerTim | AixLib.Utilities.Time.Types.ZeroTime.NY2016 | Enumeration for choosing how reference time (time = 0) should be defined |
| Integer | yearRef | 2016 | Year when time = 0, used if zerTim=Custom |
Components
| Type | Name | Default | Description |
|---|---|---|---|
| AixLib.Utilities.Time.CalendarTime | calTim | ||
| Modelica.Blocks.Interfaces.RealInput | T_flow_ev | Temperature at evaporator inlet | |
| Modelica.Blocks.Interfaces.RealInput | T_ret_ev | Temperature at evaporator outlet | |
| Modelica.Blocks.Interfaces.RealInput | T_oda | Outdoor air temperature | |
| Modelica.Blocks.Interfaces.RealInput | m_flow_ev | Mass flow rate at evaporator | |
| Modelica.Blocks.Interfaces.RealOutput | 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. |
