Information

This model calculates the filtration efficiency, eps, using cubic Hermite spline interpolation of the filter dataset (see Buildings.Fluid.AirFilters.Data.Characteristics.FiltrationEfficiencyParameters) with respect to the input rat.

The rat is the relative mass of the contaminant that is captured by the filter, and is calculated by

rat = mCon/mCon_max,

where mCon is the mass of all the captured contaminants, and mCon_max is the maximum mass of the contaminants that can be captured.

    Changed rat to be not bounded by 1 as there is no need for such a bound.
