چکیده
This study embraces a steady numerical simulation of thermodynamic model optimized for an ammonia-water diffusion absorption refrigeration (DAR) cycle with hydrogen or helium as the auxiliary gas. A DAR cycle has been examined due to the fact that such cycles may operate under low cooling load without a mechanical pump. To this end an Electrolux refrigerator manufactured by Dometic of Sweden is examined. The generator of this system has been modified to have it coupled with a parabolic trough collector in order to enhance the heat transferred to the generator. Besides, considering temperature range gained by the collector, the DAR cycle has been optimized. Finally, the results are validated against available experiments. It was found that the effects of parameters such as generator temperature, ammonia solution concentration, pressure of the cycle and the temperature of the main components of the cycle can change the COP by ±10% .
