The dynamic sorption characteristics of organic sorbent materials have been studied by using fluidized bed with a cooling pipe. The organic powder type sorbent made from a bridged complex of sodium polyacrylate which is one of the sorption polymers is adopted in this study. Sorption rate of water vapor and the variation of temperature in the sorbent bed with time were measured under various conditions. As a result, sorption ratio increases and the completion time for the sorption process decreases by using a cooling pipe. Furthermore, the non-dimensional correlation equations were obtained for water vapor mass transfer under sorption process in terms of relevant non-dimensional parameters.

Energy consumption is increasing gradually in the world. It is due to the growth of air conditioning need in response to higher summer temperatures. This causes an increase in electricity demand. Solar cooling is a relatively new, reliable and clean application of proven refrigeration technology able to improve comfort conditions, limit the impact on the environment and save energy. The use of "desiccant cooling" technique is particularly interesting because it avoids the refrigerants use that have a negative effect on the ozone layer (CFC, HCFC, HFC ...). The main element in a desiccant cooling system is the desiccator. In this study, an experimental test bed was made in the Energy and Thermal Systems Laboratory "LESTE" at National Engineering School of Monastir, Tunisia. This bench is designed to examine the optimal conditions used (air flow rates effect) for a cylindrical desiccator, filled with silica gel grains, during both adsorption and desorption phases. For this aim, measurements of temperature, humidity and velocity at the inlet and outlet of the desiccator are done.

A continuous circulating of sorbent powder for sorption and desorption process in two connected fluidized beds has been developed. Two fluidized beds are arranged next to each other and connected by spiral tubes. The experiments were carried out under the various conditions such as air velocity, desorption air temperature, and sorbent powder circulation rate. Sorption and desorption characteristics of sorbent powder of the organic sorption materials show that sorption and desorption performance promoted by increasing air velocity and desorption air temperature. It was found that the spiral revolution speed has optimal value on the humidification. Furthermore, the non-dimensional correlation equations were obtained for water vapor mass transfer under sorption and desorption process in terms of relevant non-dimensional parameters.
