Abstract: A major bottle neck of enhancing the adsorption cycle¿s performance is thermal resistance if conventional thermally activation is applied. In order to overcome this obstacle, this study proposed a novel energy transport method transferred by electromagnetically activation. In order to achieve in-depth understanding of this electromagnetically transporting method, a theoretical framework for mass and energy transport was studied with microscopic control volume approach. Extensive experimentations are also carried out to measure the permittivity of type RD silica gel for simulation, to analyze the characteristic of microwave-activated desorption depending on the permittivity property, to study the effect of microwave irradiation on activation energy change, to develop a empirical relation between electric field intensity and kinetic desorption. Based on these simulation parameters and empirical equation, non-uniform model of microwave-activated adsorption chillers system is successfully developed, and the result shows that the predicted COP of this system is higher than the conventional thermally-activated system.
