Abstract:
A heat transfer system having an energy consumption level associated with an â€œas newâ€  condition, the heat transfer system comprisingan air handler for moving an air stream, the air stream comprising organic matter a heat exchanger positioned in the air stream, wherein at least a portion of the organic matter in the air stream deposits on a surface of the heat exchanger, wherein the heat exchanger includes plural fins on the surface a germicidal lamp producing UV radiation of a wavelength of 253.7 nm, the germicidal lamp having a position such that the minimum photon energy striking the surface is not less than 430 mW/cm2 wherein the organic matter deposited on the surface of the heat exchanger degrades the performance of the heat transfer system and results in an energy consumption level of the heat transfer system elevated above that associated with the â€œas newâ€  condition, the organic matter deposited on the surface of the heat exchanger is degraded and vaporized by the UV radiation and eliminated whereby energy consumption of the heat transfer system is maintained substantially at the energy consumption level associated with the â€œas newsâ€  condition.
