摘要

The present study proposed 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 coefficient of performance (COP), but also contributes in the reduction of delivered chilled water fluctuations. In a conventional adsorption chiller operation, the appropriate pre-heating/pre-cooling 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 pre-heating/pre-cooling. Simulation results showed that the new cycle time was effective for both RD type silica gel-water and CaCl{sub}2-in-silica gel-water pairs, and the cooling capacity was increased as much as by 6%.
