Résumé

This study proposes a new cycle time allocation in silica gel-water based adsorption chillers to enhance their performances. The new cycle time allocation not only improves the cooling capacity and COP, but also contributes in the reduction of delivered chilled water fluctuations. In a conventional adsorption chiller operation, the appropriate preheating/precooling process enhances the cooling capacity, whereas the excess pre-heating/pre-cooling time abates the average cooling capacity. The proposed new cycle time allocation allows the continuous cooling effect over the cycle without sacrificing the effect of preheating/precooling. Simulation results showed that the new cycle time was effective for both RD type silica gel-water and CaCl2-in-silica gel-water pairs, and the cooling capacity was increased as much as by 6%.
