Based on a mathematical model, the characteristics of this component were discussed. The performance of a solar refrigeration system consisting of the adsorber was analyzed numerically. The distribution of adsorbent temperature and its variation with time were derived. In theory, such system has higher performance than the general adsorption system. Some characteristic parameters that are key to the performance of system were discussed and the designing optimization regarding the system was considered.
