Waste heat driven dual-mode, multi-stage, multi-bed regenerative adsorption system

摘要: Abstract Over the past few decades there have been considerable efforts to use adsorption (solid/vapor) for cooling and heat pump applications, but intensified were initiated only since imposition of international restrictions on production utilization CFCs HCFCs. In this paper, a dual-mode silica gel–water chiller design is outlined along with performance evaluation innovative chiller. This utilizes effectively low-temperature solar or waste sources temperature between 40 95 °C. Two operation modes are possible advanced The first mode will be work as highly efficient conventional where driving source 60 second an three-stage available very low (between 60 °C). With in combination coolant at 30 °C, no other cycle except staged regeneration operational. drawback operational its poor efficiency terms capacity COP. Simulation results show that optimum COP values obtained temperatures 50 55 °C mode, 80 85 °C single-stage, multi-bed mode.
