ANTI-MICROBIAL HEAT TRANSFER APPARATUS

摘要

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.

1. An anti-microbial heat transfer apparatus comprising:
a hybrid coil having multiple rows of fins and tubes, the fins and tubes being divided into an upper portion and a lower portion, the fins of the upper portion including copper and having a first height and the second portion having a second height; inside the tubes are configured to receive a flow of chilled medium therethrough to cool a surface of the fins and tubes to be colder than a dew point temperature of surrounding air such that when air flows across the hybrid coil, condensate is formed on the surface of the fins, wherein gravity causes the condensate to drip copper ions from the fins of the upper portion to the lower portion of the coil and; wherein the first height of the upper portion is less than the second height of the second portion, which is determined by an amount of condensate needed to transfer a suitable amount of copper ions from the upper portion to the lower portion of the hybrid coil to kill and/or inhibit microbial growth on the lower portion of the hybrid coil.
