modelModificationFactor
Factor to modify nominal capacity
Extends from Modelica.Blocks.Icons.Block.
Information
This model determines the three modification factors described in IDEAS.Fluid.HeatExchangers.ActiveBeams.UsersGuide by comparing the actual values of air mass flow rate, water mass flow rate and room-water temperature difference with the nominal values. The three modification factors are then multiplied. Input to this model are the total mass flow rates of all parallel beams combined.
