| Abstract: | A novel hybrid solid adsorption-steam ejection refrigeration cycle is presented and thermodynamically analyzed.The refrigerant steam with high temperature and high pressure desorbed from the adsorbent bed is led into an ejector before it enters the condenser.Therefore the hybrid refrigeration system may produce cold not only in the adsorption course but also desorption course,and refrigeration capacity is increased.The influences of some operating parameters,such as desorption temperature and ejecting pressure,on the hybrid refrigeration cycle are discussed.The coefficient of performance of the hybrid system is comparable to that of adsorption cycle with heat recovery when operated with high desorption temperature,and the hybrid adsorption-ejection refrigeration cycle with heat recovery will greatly improve the performance of the system.Simulated results show that the hybrid refrigeration system is attractive when it is powered by high-temperature exhaust heat. |
