ASHRAE Investigates PCO to Improve Understanding
The $124,889 project was awarded to the University of Wisconsin and is expected to take two years to complete. The research will investigate a variety of stand-alone and in-duct air cleaners using PCO technology, challenging them with several airborne contaminants to identify the chemicals released.
“This research will lead to a new generation of air cleaners that have both low-energy operation and low release of chemicals,” said Carolyn Kerr, a member of ASHRAE Technical Committee 2.3, Gaseous Air Contaminants and Gas Contaminant Removal Equipment, which is overseeing the project. “This will assist in providing an optimal indoor environment for buildings, vehicles, and facilities for comfort, health, and productivity of occupants.”
