Etude des performances d'un système de refraichissement evaporatif par désorption

In this paper the performance of a desiccant cooling system was evaluated. The system comprises a desiccant wheel in tandem with a thermal wheel with evaporative coolers in both air supply and return air streams before the thermal wheel. It allows cooling and dehumidifying air without using conventional refrigerants. A computer simulation was developed to study the effects of various designs and outdoor air conditions on the performance of the system. The simulations were run with SPARK, an object oriented program that allows creation of very flexible tools.
