A non-stick coating, which inhibits frozen moisture accumulation, is applied to the exterior exposed portions of a refrigerant/air heat exchanger, which heat exchanger is comprised of a capillary tube/plate means/design, which plate has an exterior surface that is comprised of at least one of raised dots, ridges, trenches, and a flat surface, which means/design facilitates the shedding of frozen moisture and maximizes heat exchanger surface area exposure to the air; for use in conjunction with an air source heat pump system, an evaporative cooling system or a chiller, or as a supplement to a water-source heat pump system or to a direct expansion heat pump system; and for use with any other refrigerant-based heating system or cooling system.
