Özet
This study was conducted to analyze the thermodynamic performance of triple-effect absorption cooling systems. By making a comparative evaluation with various models mentioned in the literature, the effects of generator temperatures and pump power consumption on the system performance were examined in detail. The study was carried out at two different operating conditions, generator temperature 150 °C and 200 °C; in both cases, the system's COP value and energy consumption amounts were measured. The findings showed that the increase in generator temperature significantly increased the COP value; especially at 200 °C, the COP value was measured as 1.788, revealing that the system has more energy production capacity at high temperatures. It was also determined that the pump power consumption increased in direct proportion to the temperature increase, which emphasizes the need for improvement in pump design and control strategies. As a result, it is recommended to optimize generator temperatures and carefully manage pump energy consumption to increase the energy efficiency and performance of triple-effect absorption cooling systems. This study provides significant contributions to the energy efficiency and cost effectiveness of the system and can form a basis for future research to further improve system design and operating strategies.
