| Testing and evaluation of indoor air cleaning devices based on adsorptive or catalytic VOC reduction (2008) | |||||||||
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. | |||||||||
