A process and apparatus for open cycle desiccant cooling wherein the process stream and regeneration stream are divided into a plurality of radial stream segments by non-parallel partitions forming unequal face segments in the desiccant wheel and the heat wheel for the same stream segment. The unequal face segments in the desiccant wheel and the heat wheel provide differing temperature profiles at the face of each wheel and allow obtaining desired temperature profiles for heat exchange and moisture adsorption. The process of this invention results in reduction of the radial speed of the heat wheel to less than 4 providing high effectiveness of the heat wheel increasing the capacity and the COP of the system.
