Buildings.Obsolete.Fluid.Movers.Validation.ControlledFlowMachine
Fans with different control signals as input
Information
This example demonstrates the use of the flow model with four different configurations. At steady-state, all flow models have the same mass flow rate and pressure difference. Note thataddPowerToMedium=false
since otherwise,
Dymola computes the enthalpy change of the component as a fraction (k*m_flow+P_internal)/m_flow
which leads to an error because of 0/0
at zero flow rate.

Buildings.Obsolete.Fluid.Movers.Validation.SpeedControlled_Nrpm
Fan with zero mass flow rate and speed as input
Information
This example demonstrates and tests the use of a flow machine whose mass flow rate is reduced to zero.
The fans have been configured as steady-state models. This ensures that the actual speed is equal to the input signal.
