Hourly performance prediction of ammonia-water solar absorption refrigeration

► Hourly performance investigation of solar absorption NH3-H2O refrigeration system is performed. ► Hourly atmospheric temperature and solar radiation on July 29 for Adana province in Turkey were used in the analysis. ► Optimum generator temperature for evacuated tube collector type was determined as higher than 110 °C. ► COPcooling was calculated in the range of 0.243-0.454 between hours 09:00 and 16:00.
