Enhancing the Performance of Solar Air Heating Systems: Techniques and Innovations

Abstract

Recently, tubular solar stills are being intensively studied as a feasible and effective technique for solar desalination. This innovative technological framework is fundamentally based on the sustainable and eco-friendly paradigm that promotes environmental consideration and resource efficiency. This comprehensive review has highlighted the series of recent improvements in essential design innovations, the performance of advanced materials, and the application of efficiency optimization techniques. For instance, the use of Phase Change Materials (PCMs), nanocomposites, multi-staging boiling systems, and implementation of structural modifications such as cascading tubular designs and various geometrical alterations have underlined the crucial importance of enhancing thermal efficiency and maximizing daily water productivity. The results obtained from multiple studies show that these pivotal innovations have the potential to be highly disseminated across different regions, thus making significant strides towards overcoming the persistent issue of freshwater scarcity. Additionally, they can be applied in a scalable and practical approach. Future directions point towards the integration of artificial intelligence and the use of hybrid renewable energy systems to further optimize performance, adaptability, and efficiency, allowing for an insightful approach to addressing water shortages effectively.
