3910 -- Computer Simulation of a Silica Gel-Water Adsorption Refrigeration Cycle -- The Influence of Operating Conditions on Cooling Output and COP PDF

This work deals with the use of adsorption refrigerant cycles driven by waste heat of near ambient temperature. A parametric study was conducted by computer simulation to determine the effects of operating conditions on cooling output and coefficient of performance (COP). A simulation program verified the influence of operating temperatures (hot and cooling water), water flow rates, and adsorption-desorption cycle times. The most influential parameter is the operating temperatures, followed by water flow rates. Cycle time is less influential in quantitative terms but qualitatively is very important.
