modelSingleToMultiple
Single inlet port, multiple outlet ports
Information
This is a model of a one-to-many fluid connector with an
optional control volume.
It is typically used to represent an inlet manifold or
a single pipe diverging into multiple junctions.
Parameters
| Type | Name | Default | Description |
|---|
| Integer | icon_offset | 0 | Offset in y-direction between inlet and outlet in icon layer |
| Integer | icon_dy | 100 | Distance in y-direction between each branch in icon layer |
| Buildings.Templates.Components.Types.IntegrationPoint | icon_pipe | Buildings.Templates.Components.Types.IntegrationPoint.None | Pipe symbol |
| Configuration |
| Integer | nPorts | | Number of ports |
| Nominal condition |
| Modelica.Units.SI.MassFlowRate | m_flow_nominal | | Nominal mass flow rate |
| Dynamics › Nominal condition |
| Modelica.Units.SI.Time | tau | 10 | Time constant at nominal flow |
| Dynamics › Conservation equations |
| Modelica.Fluid.Types.Dynamics | energyDynamics | Modelica.Fluid.Types.Dynamics.DynamicFreeInitial | Type of energy balance: dynamic (3 initialization options) or steady state |
| Assumptions |
| Boolean | allowFlowReversal | true | Set to true to allow flow reversal, false restricts to design direction (port_a -> ports_b) |
| Advanced › Diagnostics |
| Boolean | show_T | false | Set to true if actual temperature at port is computed |
