Résumé

A new 2-D analytical solution is presented and validated using the data collected from our custom-built gravimetric large pressure jump test bed and two-sorber bed sorption test bed. The proposed closed-form 2-D transient solution includes all salient thermophysical and sorption properties, heat exchanger geometry, and operational conditions as well as the thermal contact resistance at the interface in sorber beds. It is shown that the optimum amount of thermally conductive additive in the sorbent depends on the geometrical and heat transfer characteristics of the sorber bed and the cycle time. Furthermore, it is shown that the sorber bed geometry, heat transfer characteristics, sorption composite composition and cycle time can have conflicting effects on specific cooling power and coefficient of performance and should be optimized simultaneously to establish an optimal design.
