This second edition of a hugely important work on this subject still plugs a gap in the literature. It is a source of crucial support to the planner in the design of solar assisted air-conditioning systems, which use solar collectors as a heat source. Air conditioning contributes significantly to the energy consumption of buildings in many countries and a promising possibility for energy reduction is the use of solar thermal energy in solar-assisted air conditioning systems. However, until today only a few systems have been installed world-wide and design and operation experiences are fairly poor.
Air conditioning contributes significantly to the energy consumption of buildings in many countries. A promising possibility for energy reduction is the use of solar thermal energy in solar-assisted air-conditioning systems. The main advantage of this technology is that cooling loads and solar gains occur at the same time, at least on a seasonal level. However, until now only a few systems have been installed world-wide and design and operation experiences are fairly poor. This new handbook provides support for the design of this exciting and innovative technology.
Air conditioning system is one of the major consumers of electrical energy in many parts of the world today. It represents between 40 and 70% of the energy consumption in commercial buildings. The demand of energy for air conditioning systems is expected to increase further in the next decades due to the population growth, the new economic boom, and the urbanization development. The rapid growth of air conditioning and electricity consumption will contribute further to climate change if fossil and nonrenewable resources are used. More energy-efficient and renewable energy-based air conditioning systems to accomplish space cooling are needed. This book intends to provide the reader with a comprehensive overview of the current state of the art in sustainable air conditioning technologies and focus on the most recent research and development on green air conditioning systems including energy-efficient and renewable energy-based air conditioning systems.
The support for polygeneration lies in the possibility of integrating different technologies into a single energy system, to maximize the utilization of both fossil and renewable fuels. A system that delivers multiple forms of energy to users, maximizing the overall efficiency makes polygeneration an emerging and viable option for energy consuming industries. Polygeneration Systems: Design, Processes and Technologies provides simple and advanced calculation techniques to evaluate energy, environmental and economic performance of polygeneration systems under analysis. With specific design guidelines for each type of polygeneration system and experimental performance data, referred both to single components and overall systems, this title covers all aspects of polygeneration from design to operation, optimization and practical implementation. Giving different aspects of both fossil and non-fossil fuel based polygeneration and the wider area of polygeneration processes, this book helps readers learn general principles to specific system design and development through analysis of case studies, examples, simulation characteristics and thermodynamic and economic data. Detailed economic data for technology to assist developing feasibility studies regarding the possible application of polygeneration technologies Offers a comprehensive list of all current numerical and experimental results of polygeneration available Includes simulation models, cost figures, demonstration projects and test standards for designers and researchers to validate their own models and/or to test the reliability of their results
Our energy system faces a fundamental transformation and renewable energies will play a dominant role in the future energy supply. One of the promising solutions is the use of solar thermal energy in buildings, for cooling, heating and domestic hot water preparation. Solar thermal systems for providing heat and cold to industrial processes show a high potential, too. In the last decade, the application of solar driven cooling systems achieved a significant progress. Steps forward have been taken in the design of system concepts to specific needs and in more reliable and efficient operation of the installed plants. New systems are available on the market and cover a broad range of cooling capacities and driving temperatures. This handbook provides an overview on the various solutions to convert solar heat into useful cooling, reports about experiences made with realized installations and gives support in the design process. Its use will strongly contribute to achieve high quality solar cooling systems which provide significant energy savings and fulfil the user’s requirements in a safe and reliable way.
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.
