New Air Cleaning Strategies for Reduced Commercial Building Ventilation Energy

New Air Cleaning Strategies for Reduced Commercial Building Ventilation Energy ? FY11 Final Report

“…During that first year, three air cleaning technologies were evaluated, and results summarized in our first report (Sidheswaran et al 2010).…”

“…Details of the experimental setup and electrothermal regeneration methods can be found elsewhere (Sidheswaran et al, 2010;Sidheswaran et al, 2012). In electrothermal regeneration, the activated carbon is heated by passing an electrical current through the ACF media.…”

“…In electrothermal regeneration, the activated carbon is heated by passing an electrical current through the ACF media. With the ACF deployed as a pleated filter 10 cm deep, the air velocity through the media will typically be about 0.5 m s The physical properties of the VOCs used in this study can be found in other previous reports (Sidheswaran et al, 2010;Sidheswaran et al, 2012). In the results reported here, one cycle refers to a 12 hour adsorption period followed by a 15 minute electrothermal regeneration period at 150 o C at 1/100th face velocity used during air cleaning.…”

“…In the results reported here, one cycle refers to a 12 hour adsorption period followed by a 15 minute electrothermal regeneration period at 150 o C at 1/100th face velocity used during air cleaning. (Sidheswaran et al, 2010) it was inferred that prolonged operation of the cloth at such conditions may lead to a marginal decrease in performance.…”

“…We hypothesized that a double layer system would have a sufficiently high VOC removal efficiency, including for formaldehyde, with high air velocities to make it possible to deploy ACF filters with limited pleating that are 5 cm deep or less. The experimental methods are the same as those described earlier (Sidheswaran et al, 2010). Two layers of ACF cloth were fitted in a filter holder system and subjected to continuous adsorption and regeneration…”
