.Buildings.Fluid.AirFilters.Data.Generic

Information

Record that contains performance parameters for air filters.

It is used as a template of performance data for the filter models in Buildings.Fluid.AirFilters.

The default value for the flow exponent is set to m=0.85, which is the average of the inverse of the value a in Li et al., 2022.

The filter flow resistance model increases the pressure drop based on the mass accumulated in the filter. This is computed in Buildings.Fluid.AirFilters.BaseClasses.PressureDropWithVaryingFlowCoefficient using the input dpCor = b^M, where M is the dimensionless ratio of the mass that is accumulated, with M=0 for a clean filter and M=1 for a filter that accumulated the mass mCon_max. If dpCor=2, at the nominal mass flow rate m_flow_nominal, there will be twice the pressure drop compared to dp_nominal. Hence, the achieve this, set b=2.
