Abstract

Abstract: A study of a solar absorption refrigerating machine (water-ammonia) is led in the Moroccan climate, precisely in Rabat site with coordinates: latitude 34°02' North and longitude 06°48' West). A simulation program, written in FORTRAN, is performed to simulate the thermodynamic machine operations using real climate data of radiation and temperatures. The studied machine is equipped with a distillation column to purify the ammonia vapor exiting the boiler, which has a negative effect on the machine performances. The obtained results show that equipping the machine with a distillation column has a great effect in its thermodynamic performances by lowering the operating temperature of the hot source and increasing considerably the solar performance coefficient by (30%).
