Description:
The report gives results of a project to develop and refine surface and airborne contamination
measurement techniques that can be used to evaluate air conveyance system (ACS) cleaning.
(NOTE: ACS cleaning is advertized to homeowners as a service having a number of benefits,
including the improvement of indoor air quality. Because ACS cleaning includes many procedures applied to many different duct systems, evaluation has been difficult, and the effectiveness of ACS cleaning has not been adequately measured.) The research was in support of a field study to be conducted later. To this end, a pilot air conveyance system (PACS), using full-size residential heating and air-conditioning (HAC) equipment, was constructed and operated to provide a controlled, artificiallay soiled, ACS environment. The PACS consisted of ducts, an HAC unit, a dust mixing room, and instrument room, and a dust generation andsystem. Three types of duct systems were evaluated with the proposed measurement methods under soiled and unsoiled conditions. Each duct system was then cleaned by professional ACS cleaners and reevaluated. As a result of the pilot study, the surface contamination measurement methods were evaluated over a range of conditions and improved. The significance of acquired results in an actual residence was not determined.
