Performance of a Solar-driven Air-cooled NH_3H_2O Absorption Refrigeration Cycle

This paper proposed a solar-driven air-cooled NH3H2O absorption refrigeration cycle,which can increase energy efficient ratio by recovering heat from rectifier and absorber,reduce generating temperature,and realize air-cooled and the effective use of solar energy.Based on the establishment of thermal dynamic mathematical model of each component,the cycle performance was calculated by programe.The influences of the heat source temperature,evaporating temperature,condensing temperature on the coefficient of performance of the refrigerator were analyzed,which lays the foundation for optimization design of refrigeration system.
