• Abstract:

  The growing water shortage, driven by population growth and industrialization, threatens to affect two-thirds of the world's population by 2030. Desalination is a solution that converts saline water into drinking water, with lower energy consumption and low environmental impact. Among desalination technologies, the humidification-dehumidification (HDH) system has attractive potential in terms of efficiency and applicability in regions with limited water resources. The objective of this study was to conduct a bibliometric analysis to show the development and trends of scientific articles published on HDH systems during the period from 2000 to 2023, analyzing trends, authors, and topics researched. A descriptive PRISMA methodology was used. From this, a significant increase in the publication of articles was observed, peaking in 2022, with a majority of articles in the areas of engineering and environmental sciences. In addition, searches for key terms (air bubble, spray evaporation, exergy, and cooling) are discussed, reflecting a growing interest in improving energy efficiency and distilled water production capacity. Furthermore, the collaborative analysis provided a multidisciplinary and international approach. The study highlights trends and opportunities for future research in HDH, such as the combination of advanced optimization technologies and the development of systems adaptable to specific conditions. HDH technology is a tool for addressing the global water crisis, contributing to significant advances toward sustainability.
