Abstract
Supply air filtration is needed to reduce outdoor pollutants from entering indoors. This is especially important during large scale releases of toxic agents in the air. In order to study the filter performance and protection of building occupants from airborne threats more accurately, a real-time test system was developed at VTT. The system consists of sampling tubes, a micromanometer, particle detectors and a valve system controlled by a laptop computer. The system is automated and it measures online pressure drop of supply air filters, particle concentrations upstream and downstream of the filters, as well as particle concentrations in the HVAC system's exhaust air. The measurement system was installed in two different test sites in Finland and in China with new type of high efficiency filters.
