Optimization strategies for absorption chillers: A performance study on natural gas and LPG utilization

This research aims to investigate optimization strategies for absorption chillers utilizing natural gas and liquefied petroleum gas (LPG) to enhance performance and efficiency. The study employs a combination of experimental analysis and mathematical modeling to evaluate the performance of absorption chillers operating with these two fuels. Through a series of controlled experiments and simulations, key performance metrics such as coefficient of performance (COP), energy consumption, and emissions are analyzed. The optimization process involves the application of advanced algorithms to identify the most efficient operational parameters for each fuel type. The key findings indicate that absorption chillers using LPG demonstrate a higher COP compared to those using natural gas, albeit with increased emissions. Conversely, natural gas-fueled chillers exhibit lower emissions but slightly reduced efficiency. The study also identifies optimal operating conditions for both fuels, which significantly improve overall performance. These findings have substantial implications for the HVAC industry, particularly in regions where natural gas and LPG are prevalent. The optimized strategies can lead to significant energy savings and reduced environmental impact, making absorption chillers a more viable option for sustainable cooling solutions. The results also provide a foundation for future research on further enhancing the performance and sustainability of absorption chillers.
