Abstract
A method and apparatus wherein a germicidal lamp's tube is positioned in a particular manner relative to the HVAC system such that the system coil and drain pan components are subjected to UVC radiation and an increased flux density of photons emitted therefrom, and the photons are continuously reflected and directed within and through the coil until absorbed. In this manner the flux density of the photons is increased, as well as the dosage of the photons actually applied to a surface or airborne microorganism, minimizing the occurrence of HVAC-sourced bioaerosols and effectively and efficiently killing the mold and bacteria that grow on the coil and in the drain pan of a HVAC system without producing a secondary contaminant.
