Abstract:
A heat transfer system having an efficiency associated with an ""as new"" condition, the heat transfer system comprising:an air handler for moving an air stream, the air stream comprising organic matter;a heat exchanger positioned in the air stream from the air handler, wherein at least a portion of the organic matter in the air stream deposits on a surface of the heat exchanger;a germicidal lamp having a light string centerline and producing UV radiation, the germicidal lamp having a position a distance from the surface of the heat exchanger equal to about forty to ninety percent of the light string centerline;wherein the organic matter deposited on the surface of the heat exchanger degrades the performance of the heat transfer system and results in an efficiency of the heat transfer system below that associated with the ""as new"" condition, the organic matter deposited on the surface of the heat exchanger is degraded and vaporized by the UV radiation and eliminated;whereby the efficiency of the heat transfer system is maintained substantially at the efficiency associated with the ""as new"" condition.
