Abstract
- An experimental investigation of the influences ammonia concentration variation to the performances of pump less ammonia-aqua absorption refrigeration system with water flooding evaporator is described. The heat generated in generator and refrigerating effect in evaporator, cooling capacity, coefficients of performance (COP) are investigated. The objective of this study is to investigate the characteristic and influences of the ammonia concentration variation to the performance of pump less absorption refrigeration system with water flooding evaporator as a refrigeration load.. In this research, the generator temperature has been setting constant in 80°C using electric heater, the ammonia concentration in 500 ml solution would be varied in 18%, 27%, 37%, 47%, and 59%. It is concluded that heat generated in generator and refrigerating effect in evaporator decrease with increasing ammonia concentration, while the cooling capacity and COP would increase with increasing ammonia concentration. As a result, it is found that increasing the ammonia concentration would effect on increasing of cooling capacity and COP. The highest the ammonia concentration, the highest cooling capacity and COP would be resulted. The highest cooling capacity and COP resulted respectively are 0.7180 kW and 0.829 at 59% ammonia concentration. [ABSTRACT FROM AUTHOR]
