Modeling the performance of two-bed, silica gel-water adsorption chillers

This article presents a transient model for a two-bed, silica gel-water ads orption chiller. Compared with our previous cyclic-steady-state model, we f ound very good agreement between our model prediction and experimental data . We found that, regardless of the initial mass distribution, the chiller w as able to achieve the same cyclic-steady-state within four cycles or 1800 a. We also demonstrated that the manufacturer had empirically evolved to se lect a fixed switching and cycle time such that the best peak evaporator te mperature suppression, and near maximum cooling capacity can be achieved by a compact design.
