modelPowerInterface
Partial model to compute power draw and heat dissipation of fans and pumps
Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
Information
Block that implements the functions to compute the heat dissipation of fans and pumps. It is used by the model IBPSA.Fluid.Movers.BaseClasses.PartialFlowMachine.
Parameters

| Boolean | motorCooledByFluid | Flag, true if the motor is cooled by the fluid stream | |
| Modelica.SIunits.VolumeFlowRate | delta_V_flow | Factor used for setting heat input into medium to zero at very small flows | |
| Advanced | |||
| Boolean | homotopyInitialization | true | = true, use homotopy method |
Connectors
