Abstract: In this study, a thermodynamic simulation of a solar absorption refrigeration system has been carried out. The binary mixture considered in the present investigation was NH3-H2O (Ammonia-Water). The influences of operating conditions and effectiveness of heat exchanger on the thermal loads of components, coefficients of performance (COPc, COP) and efficiency ratio (į) are investigated. It is concluded that the COPc and COP values increase with increasing generator and evaporator temperatures but decrease with increasing condenser and absorber temperatures. The (į) value varies with these temperatures. Also, the effects of solution heat exchanger on the performance, efficiency ratio of the system and fluid temperatures are compared. It is found that the effectiveness of heat exchanger determines the maximum temperature that can be used in order to obtain the maximum COP out of the system.
Keywords: Performance parameters, Efficiency ratio, Solar energy, Refrigeration, NH3-H2O
