Abstract

A non-stick coating (1), which inhibits frozen moisture accumulation, is applied to exterior exposed portions of heating and cooling systems where ice or other frozen moisture can accumulate and impair system design operational efficiencies; where heat exchange tubing (2) and fins are downwardly sloped or angled; where an optional capillary tube/plate means/design, which plate (12) has an exterior (16) surface (17) that is comprised of at least one of raised dots, ridges, trenches, and a flat surface is utilized; with an optional protective shell encasement (5) which can be shaped to provide a vena contracta effect; with an optional electric fan (9) to enhance airflow for heat exchange; with an optional electric vibrator (10) to enhance inhibition of frozen moisture accumulation; with a downwardly sloped base (8) to direct falling frozen moisture away from the heat exchange equipment.
