modelFlowCoefficientCorrection
Flow coefficient correction factor due to the contaminant accumulation
Extends from Modelica.Blocks.Icons.Block (Basic graphical layout of input/output block).
Information
This model calculates the flow coefficient of the filter by
dpCor = brat,
where b is the flow resistance coefficient, which must be greater than 1,
rat is the relative mass of the contaminant that is captured by the filter
as described in
Buildings.Fluid.AirFilters.BaseClasses.FiltrationEfficiency.
