RÉSUMÉ

In this study, the effect of geometric parameters of a rectangular bed whose length and height, the diameter of adsorbent particles, and the effect of the minimum and maximum temperatures of the adsorption cycle on the performance of the adsorbent bed are investigated numerically to find a proper adsorbent bed design for the highest specific cooling power (SCP). The governing equations which are mass conservation, motion, and energy equations for the adsorbent bed and mass transfer equations for the adsorbent particles with appropriate initial and boundary conditions are solved and the distributions of temperature, concentration, and pressure for the entire bed are found and then the values of SCP are calculated. Based on the Taguchi method, L9, an orthogonal array is chosen to reduce the numerical runs from 81 to 9. Three different levels for each investigated parameter are considered and the best adsorbent bed design with SCP of 229.15 W/kg is found. The results showed that the adsorbent particle radius and the maximum and minimum temperature difference in the cycle have the most and the least effect on the performance of an adsorbent bed.
