ABSTRAKT

Desiccant materials open new possibilities in air-conditioning technology. In desiccant cooling installations, air is dehumidified via a desiccator and its temperature consequently increases. Air temperature is then deceased by heat exchanger and evaporator while its humidity increases. Desiccant cooling installations require a relatively moderate heat source for regeneration. Solar energy is an interesting source. This technology is profitable for the Tunisian climate because moisture is important especially in certain coastal zones. This study compares two desiccators directly in series and using an exchanger between them for different climates and examines the possibility of using a desiccator instead of a desiccant wheel and a second desiccator at the desorption phase in place of the evaporator.
