Testing and evaluation of indoor air cleaning devices based on adsorptive or catalytic VOC reduction
Abstract
For reducing volatile organic compounds (VOCs) including odorous compounds indoors adsorptive and catalytic systems are available. These devices are either stand-alone appliances or are integrated into (multifunctional) building products. For performance testing of these systems a method was developed which allows long term investigations on the reduction efficiency using different substances in realistic indoor concentrations. Adjustment of realistic indoor concentrations is achieved by a micro dosing device connected to an emission test chamber containing the sample to be tested. This set-up allows adjustment and control of all boundary conditions depending on the planned application field. With this test set-up different air cleaning devices have been investigated, e. g. based on adsorption, catalytic destruction, catalytic photo oxidation or combined systems.
