.Buildings.Fluid.Movers.BaseClasses.Validation.NegativePressureOrFlow

Information

Without the constraint that W_flo = V̇ Δp ≥ 0, this validation model would produce negative computed mover power when the pressure rise or the flow rate is forced to be negative, as shown below.

  • Remade this model with Buildings.Fluid.Movers.BaseClasses.FlowMachineInterface instead of using a full mover model so that forcing a flow rate and a pressure rise is more straightforward.
  • Changed parameterisation so that the result curve is clearer.
  This is for #2668.
• June 6, 2022, by Hongxiang Fu:
  First implementation.
  This is for IBPSA, #1621.
