modelHeaterFan_noReverseFlow
Heater and fan in series, model configured to not allow flow reversal
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example demonstrates how to configure a model with a heater
and a fan that causes a pressure rise in the air stream.
The model is identical with
Buildings.Fluid.FMI.Validation.HeaterFan
except that reverse flow is not allowed due to the parameter
allowFlowReversal=false.
Consequently, the connectors for the fluid properties for the reverse flow
are removed, and the blocks on the right hand side of the model
Buildings.Fluid.FMI.Validation.HeaterFan
have been deleted.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | allowFlowReversal | false | = true to allow flow reversal, false restricts to design direction (inlet -> outlet) |
| Boolean | use_p_in | false | = true to use a pressure from connector, false to output Medium.p_default |
| Modelica.Units.SI.MassFlowRate | m_flow_nominal | Q_flow_nominal/1000/10 | Nominal mass flow rate |
| Modelica.Units.SI.PressureDifference | dp_nominal | 2000 | Pressure |
| Modelica.Units.SI.HeatFlowRate | Q_flow_nominal | 1000 | Heat flow rate at u=1, positive for heating |
