As noted in the 2011 column, (1) UVGI cooling coil treatment has been the subject of prior research, but these studies only investigated changes in microbial populations on cooling coil and air-handling unit surfaces.
Both hospitals were able to mitigate the coil's biofilm and restore optimum performance by applying a minimum UVGI intensity at the ccoil's surface of [greater than or equal to] 1,000 [micro]W/[cm.sup.2].
Traditional upper room UVGI systems use mercury lamps as UVC light sources and are left on continuously in occupied rooms and congregate settings.
Baseline cultures were taken just prior to intervention of the UVGI and ninety days post UVGI installation.
Results of a recent study there indicate ultraviolet germicidal irradiation (UVGI) of drip pans and cooling coils within HVAC systems substantially reduced microbial contamination and work-related illness.
Some facilities installed ultraviolet germicidal irradiation (UVGI) lamps in HEPA filter banks, although the efficacy of using UVGI for control of SARS-associated coronavirus was uncertain.
One such technology, ultraviolet germicidal irradiation (UVGI), has long been used to inactivate microbial aerosols, mostly in the occupied spaces of medical facilities.
Control measures include the use of adequate ventilation systems, which may be supplemented in high-risk areas with high-efficiency particulate air (HEPA) filtration, and ultraviolet germicidal irradiation (UVGI).
Since the 1990s, ultraviolet germicidal irradiation (UVGI), or light in the UV-C wavelength (specifically 253.7 nm), has been used in HVAC&R equipment to maintain or return cooling capacity to as-built conditions by maximizing heat exchange efficiency.
