Résumé

The study aims at clarifying the performance of silica gel-water adsorption refrigeration cycle with mass recovery process. Two cases of mass recovery process are studied and the performances are compared with the performances of conventional two-bed adsorption cycle. One is the conventional mass recovery process in which no heating and cooling are applied to the beds, the other is the newly proposed mass recovery process in which beds heating and cooling process are continued. A cycle simulation program is developed to predict the performance of the proposed cycle. The results show that the proposed strategy along with mass recovery cycle improves cooling capacity significantly. It is also seen that COP values of the cycle without heating and cooling is increased by 28%, and cooling capacity of the mass recovery cycle with heating and cooling is increased from 11% than those of conventional single stage cycle at hot water temperature 60°C. The results show that mass recovery process has influential effect if the heat source temperature is low.
