modelSourceIdeal
Simple supply node model with ideal flow source and return port
Extends from BaseClasses.Supplies.OpenLoop.PartialSupply (Base class for modeling supply nodes in DHC systems without return lines).
Information
This model represents the supply node with an ideal pressure source and sink. It provides a prescribed supply pressure and supply temperature to the network.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Units.SI.AbsolutePressure | pReturn | Fixed return pressure | |
| Modelica.Units.SI.Temperature | TReturn | Fixed return temperature | |
| Assumptions | |||
| Boolean | allowFlowReversal (from PartialTwoPort) | true | = false to simplify equations, assuming, but not enforcing, no flow reversal |
Connectors
| Type | Name | Default | Description |
|---|---|---|---|
| Modelica.Fluid.Interfaces.FluidPort_a | port_a (from PartialTwoPort) | Fluid connector a (positive design flow direction is from port_a to port_b) | |
| Modelica.Fluid.Interfaces.FluidPort_b | port_b (from PartialTwoPort) | Fluid connector b (positive design flow direction is from port_a to port_b) | |
| Modelica.Blocks.Interfaces.RealInput | TIn (from PartialSupply) | Prescribed supply temperature | |
| Modelica.Blocks.Interfaces.RealInput | dpIn (from PartialSupply) | Prescribed pressure rise | |
| Modelica.Blocks.Interfaces.RealOutput | Q_flow |
Components
| Type | Name | Default | Description |
|---|---|---|---|
| AixLib.Fluid.Sensors.TemperatureTwoPort | senT_supply (from PartialSupply) | Supply flow temperature sensor | |
| AixLib.Fluid.Sensors.MassFlowRate | senMasFlo (from PartialSupply) | Mass flow rate sensor | |
| Sensors.TemperatureTwoPort | senT_return (from PartialSupply) | Return temperature sensor | |
| AixLib.Fluid.Sources.Boundary_pT | source | Ideal fluid source with prescribed temperature and pressure | |
| Sources.Boundary_pT | sink | Ideal sink for return from the network |
