modelModificationFactor
Factor to modify nominal capacity
Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
Information
This model determines the three modification factors described in IBPSA.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.
