(Color online) A schematic diagram of the -stage chiller, where the transport of energy from source to sink is shown. is the heat rejection to the environment during adsorption and indicates the amount of driving heat from a source near but above ambient ( for two stages, for three stages, etc.) to run the system.
(Color online) Minimum desorption temperature for each stage on pressure-concentration diagram. Here a, b, c, and d indicate thermodynamic state points, i.e., a–b defines adsorption, b–c indicates thermal swing from adsorption to desorption, c–d represents desorption, and d–a shows thermal swing from heating to cooling. stand for the number of stages.
(Color online) Minimum heat source temperatures vs the number of stage of adsorption cooling cycle. Both the analytical (◻) and experimental (▴) results are presented. Deviations between experimental data and analytical values are due to entropy generation during batch operated cycle, lack of equilibrium conditions, and heat transfer due to finite temperature differences.
(Color online) Saturated vapor temperatures are plotted against adsorbent (silica gel) temperature for three-stage adsorption chiller. Here the sink temperature is and the driving heat source temperature is .
