Using solar heat, it is further heated to condition 8 before going through the desiccant wheel to regenerate the desiccant. ... 7.10.2 liquid Desiccant Cooling System Liquid desiccants offer a number of advantages over solid desiccants.
About this book
Completely revised and updated, Principles of Sustainable Energy Systems, Second Edition presents broad-based coverage of sustainable energy sources and systems. The book is designed as a text for undergraduate seniors and first-year graduate students. It focuses on renewable energy technologies, but also treats current trends such as the expanding use of natural gas from fracking and development of nuclear power. It covers the economics of sustainable energy, both from a traditional monetary as well as from an energy return on energy invested (EROI) perspective. The book provides complete and up-to-date coverage of all renewable technologies, including solar and wind power, biological processes such as anaerobic digestion and geothermal energy. The new edition also examines social issues such as food, water, population, global warming, and public policies of engineering concern. It discusses energy transition—the process by which renewable energy forms can effectively be introduced into existing energy systems to replace fossil fuels. See What’s New in the Second Edition: Extended treatment of the energy and social issues related to sustainable energy Analytic models of all energy systems in the current and future economy Thoroughly updated chapters on biomass, wind, transportation, and all types of solar power Treatment of energy return on energy invested (EROI) as a tool for understanding the sustainability of different types of resource conversion and efficiency projects Introduction of the System Advisor Model (SAM) software program, available from National Renewable Energy Lab (NREL), with examples and homework problems Coverage of current issues in transition engineering providing analytic tools that can reduce the risk of unsustainable fossil resource use Updates to all chapters on renewable energy technology engineering, in particular the chapters dealing with transportation, passive design, energy storage, ocean energy, and bioconversion Written by Frank Kreith and Susan Krumdieck, this updated version of a successful textbook takes a balanced approach that looks not only at sustainable energy sources, but also provides examples of energy storage, industrial process heat, and modern transportation. The authors take an analytical systems approach to energy engineering, rather than the more general and descriptive approach usually found in textbooks on this topic.

About this book
Solar energy is available all over the world in different intensities. Theoretically, the solar energy available on the surface of the earth is enough to support the energy requirements of the entire planet. However, in reality, progress and development of solar science and technology depends to a large extent on human desires and needs. This is due to the various barriers to overcome and to deal with the economics of practical utilization of solar energy. This book introduces the rapid development and progress in the field of solar energy applications for science and technology: the advancement in the field of biological processes & chemical processes; electricity production; and mechanical operations & building operations enhanced by solar energy. The volume covers bio-hydrogen production and other biological processes related to solar energy; chemical processes for the production of hydrogen from water and other endothermic processes using solar energy; the development of thermo-electric production through solar energy; the development of solar ponds for electric energy production; and the mechanical operation with solar energy; the building operation with solar energy optimization and urban planning. This book is an invaluable resource for scientists who need the scientific and technological knowledge of the wide coverage of solar energy sciences and engineering applications. This will further encourage researchers, scientists, engineers and students to stimulate the use of solar energy as an alternative energy source.
Solar energy is used to regenerate the solid desiccants or to reconcentrate the liquid desiccants that are used in the dehumidifier. As early as 1955, Pennington in the U.S.A. patented a cooling system using a rotary desiccant wheel and a heat ...
About this book
Solar cooling is most effective where it is most needed - in the tropics. Most developing countries lie in the hotter climatic regions, where cooling facilities are essential to promote the well-being, productivity and comfort of the population. Paradoxically, solar air-conditioning can contribute significantly to the alleviation of the problem. This book includes fully detailed treatment of the theory and applications of the techniques involved: vapour absorption systems, solar absorption systems, solar absorption cooling, radiative cooling and desiccant cooling. Particular applications stressed include the use of passive cooling in buildings and the provision of efficient refrigeration facilities, the latter being essential for the storage of vaccines in health-care programmes for the eradication of infectious diseases throughout the developing world.
