.Buildings.Fluid.AirFilters.Examples.SpaceCooling

Information

This block is identical to Buildings.Examples.Tutorial.SpaceCooling.System3, except that an air filter is added to the cooling system.

The major input signals for the air filter are configured as follows:

• The input trace substance C_inflow.y changes from 10 µg/m³ (7.73e-9 kg/kg, assuming an air density of 1.293 kg/m³) to 15 µg/m³ (1.16e-8 kg/kg) at 12:00 (15552000+12*3600 seconds).
• The filter replacement signal repSig is false.

The expected output are:

• The filtration efficiency airFil.eps[1] decreases along with the contaminant airFil.masAcc.mCon build up.
• The fan power fan.P slightly increases, caused by the rising pressure drop across the filter as contaminants build up.

Note that these changes in filtration efficiency and pressure drop are relatively minor over the span of a single day, with more pronounced effects expected over months.
