Abstract
The study aims at investigating the performance of silica gel-water single-double combined adsorption refrigeration cycle. The rejected waste heat from the conventional single-stage adsorption chiller is usually purged to the drain. The heat that rejected from the single stage, however, can be used for regeneration of a two-stage chiller because two-stage chiller can utilize relatively low temperature heat source to drive the system. Single-Double combined adsorption refrigeration cycle can provide higher performance. Due to cascaded use of heat source, the cooling capacity of the proposed cycle is expected to be higher than that of the existing refrigeration cycle. The performance that predicted by cycle simulation is compared with the performances of conventional single stage and double stage cycles. The results show that the proposed cycle improves cooling capacity significantly in driving source temperature between 65℃ and 80℃. Single-Double combined cycle is effective if heat source temperature is middle.
