Abstract :This study analyzes the performance of ammonia-water absorption heat pump systems for Isparta province. Considering the variable climate conditions of Isparta, the effects of seasonal temperatures on heat pump performance were investigated. In the study, it was observed that the ammonia-water absorption heat pump showed acceptable performance even at low outdoor temperatures, and the efficiency of the system increased as the temperature increased. While the COP (coefficient of performance) values were 0.7981 in January, they increased to 0.8138 in September. These results reveal that ammonia-water absorption heat pumps offer a suitable solution in terms of energy efficiency in regions with climatic differences such as Isparta. In addition, when compared with the studies in the literature, it is seen that this system provides reasonable efficiency at low temperatures. The general findings of the study show that ammonia-water absorption heat pumps provide reasonable performance at low temperatures, but operate more efficiently at high temperatures. In this context, it was concluded that these systems are a suitable option in terms of energy efficiency in regions with high seasonal temperature changes, such as Isparta.
