Summary

The objective of this study is to construct mathematical expressions to estimate the optimum cycle time which maximizes the specific cooling power (SCP) of adsorption chillers with silica gel-water pair. The operating temperature conditions of hot water, cooling water and chilled water, as well as the design parameters such as heat transfer coefficient and heat capacities of the adsorbent heat exchanger and silica-gel, are taken into account to estimate the optimum cycle time. Totally 729 cases were examined to calculate the optimum cycle times from which mathematical expressions were derived. The empirical method reflecting the six parameters successfully estimates the optimum cycle time of the simulations with the coefficient of determination as high as 0.98. The performance for estimating the maximum SCP through the optimum cycle time is even better.
