Abstract
Objective. This study examines the performance indicators of a solar-powered lithium bromide absorption chiller (LBAC) in the climate conditions of Astrakhan. Method. A new mathematical model based on simulation data was developed and verified to analyze the system's performance. The model's accuracy was validated by comparing it with existing data, and calculations were performed to determine the required number of solar collectors. Result. The study showed that the efficiency of the LBAC depends on the mode of coolant supply to the absorber and condenser of the LBAC. Parallel supply demonstrated better results in terms of thermal coefficient. The dynamics of the thermal load on the generator showed that solar insolation directly affects system performance, achieving maximum efficiency at high levels of solar energy. Conclusion. The results of this study can be used to design and optimize cooling systems in hot climates, promoting more efficient use of solar energy and enhancing energy efficiency.
