Abstract Solar cooling is environmentally friendly and relies on solar energy to meet needs. In recent years, absorption chillers have gained interest as a sustainable alternative vapor compression using eco-friendly refrigerants. However, major problem with simple systems their low coefficient of performance. As result, researchers are exploring ways improve thermoeconomic efficiency. this research, three different configurations cycles compared analyzed from exergetic exergoeconomic points view. These include the cycle, combined ejector-absorption compression-absorption well flat plate collector storage tank. Ammonia sodium thiocyanate used working solution. both cycles, absorber operates at intermediate pressure, allowing pressure levels be considered. The simulations carried out EES software. results show that should considered more than other components in terms exergy exergoeconomic. It observed for same ratio ejector compressor, efficiency cycle slightly higher cycle. Also, most cases, improved performance by increasing compressor cycles. has also been shown improves
