This function is similar to BuildingSystems.Fluid.Movers.BaseClasses.Characteristics.efficiency, but takes the motor part load ratio y=Pele ⁄ Pele,nominal instead of volumetric flow rate V̇ as input and does not consider the speed of the mover.
function efficiency_yMot extends Modelica.Icons.Function; input BuildingSystems.Fluid.Movers.BaseClasses.Characteristics.efficiencyParameters_yMot per "Efficiency performance data"; input Real y "Motor part load ratio, y = PEle/PEle_nominal"; input Real d[:] "Derivatives at support points for spline interpolation"; output Real eta(unit = "1", final quantity = "Efficiency") "Efficiency"; end efficiency_yMot;
