“…[1][2][3][4][5][6][7][8][9] However, uneven drying or heating, resulting from nonuniform moisture distribution in the material to be dried and=or non-uniform distribution of the electromagnetic (EM) field in the MW cavity, is a limitation for MW applications in practice. [10,11] The EM field distribution in the cavity depends on its geometry as well as the physical and dielectric properties of the materials subjected to the MW field.…”

“…The bounding of research by small single-mode cavities is due to the uniform electric eld distribution, which led to impeding factor neglect, such as low performance. So far, most experiments have been carried out on scales less than 160 g with a volume of 1 liter [11][12][13][14][15][16][17] . Consequently, all bench-scale studies were not developed to the pilot level to dehumidify the air.…”

Dehumidification is one of the key challenges facing the air conditioning (AC) industry in the treatment of moist air. Over many decades, the dual role of heat exchangers of AC chillers for the sensible and latent cooling of space has hindered the thermal-lift reduction in the refrigeration cycle due to the requirements of water vapor removal at dew-point and heat rejection to the ambient air. These practical constraints of AC chillers have resulted in the leveling of energy efficiency of mechanical vapor compressors (MVC) for many decades. One promising approach to energy efficiency improvement is the decoupling of dehumidification from sensible processes so that innovative but separate processes can be applied. In this paper, an advanced microwave dehumidification method is investigated in the laboratory, where the microwave (2.45 GHz) energy can be irradiated onto the dipole structure of water vapor molecules, desorbing rapidly from the pores of adsorbent. Results show a significant improvement in performance for microwave dehumidification, up to 4-fold, as compared to data available in the literature.
