Abstract
An anti-microbial heat transfer apparatus comprises a hybrid coil with multiple rows of fins and tubes. The fins and tubes have an upper portion and a lower portion. The upper portion comprises fins that include copper and has a height that is different than the height of the second portion. A chilled medium inside the tubes makes the surface of the fins and tubes colder than the temperature of the dew point of the surrounding air such that a condensate is formed on the surface of the fins. Gravity causes the condensate to drip copper ions from the upper portion to the lower portion of the coil resulting in the inhibition of microbial growth on the coil.
