Abstract
A device for withdrawing heat energy from air. The device includes a layer of a substantially hydrophobic coating on a heat exchange surface. The coating has a lower surface tension than water, to repel water and prevent the formation of water condensation on the surface. For example, the coating can be a fluoropolymer such as 1,1,2,3,3,3 hexafluoropropene.
