Abstract

See full text

An HVACR system, a direct expansion evaporator, and a direct expansion heat exchanger tube arranged to evaporate a working fluid inside the tube are disclosed. The tube includes an exterior surface of the tube opposing an inner surface of the tube, and a cavity layer on the inner surface configured to evaporate the working fluid flowing in a first flow path arranged to direct the first fluid to flow through the tube and contact the cavity layer on the inner surface. A second flow path, separate from the first flow path, is arranged to direct a second fluid across the tube and to contact the extended member on the exterior surface of the tube such that the first fluid exchanges thermal energy with the second fluid.
