modelControlledVolumeFlowPump
Pump with controlled volume flow rate
Information
This model describes a pump with ideally controlled volume flow rate.
The input connectors V_flow_set can optionally be enabled via use_V_flow_set to provide time varying set points.
Use this model if the pump characteristics is of secondary interest. The actual characteristics can be configured later on for the appropriate rotational speed N. Then the model can be replaced with a PrescribedPump.
Parameters
| Type | Name | Default | Description |
|---|---|---|---|
| Boolean | Fan | false | If true fan icon else pump icon |
| Boolean | use_V_flow_set | false | = true to use input signal V_flow_set instead of V_flow_nominal |
| Modelica.SIunits.VolumeFlowRate | V_flow_nominal | Nominal volume flow rate, fixed if not use_V_flow_set | |
| Modelica.SIunits.Efficiency | eta | 0.8 | Isentropic efficiency |
| Assumptions | |||
| Boolean | checkValve | false | = true to prevent reverse flow |
