"Providing guidance to design engineers and contractors, this book illustrates in full detail how operational savings of 50 to 75 percent can be achieved with evaporative cooling technologies compared to equivalent electric-based systems. Thorough in scope, the book addresses the technical aspects of evaporative cooling, as well as a broad range of specific commercial and industrial applications. Topics include cost analysis, technology and equipment options, application guidelines, and operational and performance characteristics. The third edition adds a new chapter which shows how evaporative cooling can be integrated into large-scale HVAC systems, with discussions of achievable savings, maintenance costs, cooling tower and finned coil indirect cooling, wet bulb economizers, precooling condensed air, makeup air and return air, humidity control, and more, including sample calculations as well as demonstration and engineering data."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

Air conditioning boosts man's efficiency no less than his comfort. Air-conditioned homes, offices, and factories unmistakably raise human productivity and reduce absenteeism, turnover, mistakes, accidents and grievances, especially in summer. Accordingly, many employers every year cool workrooms and offices to raise summer profits. Employees in turn find cool homes enhancing not only comfort and prestige but also personal efficiency and income. With such economic impetus, low-cost summer cooling must irresistibly spread to all kinds of occupied buildings. Refrigeration provides our best cooling, serving well where people are closely spaced in well-constructed, shaded, and insulated structures. However, its first and operating costs bar it from our hottest commercial, industrial, and residential buildings. Fortunately, evaporative cooling is an economical substitute in many regions. First used in Southwest homes and businesses and in textile mills, it soon invaded other fields and climates. In 1946, six firms produced 200,000 evaporative coolers; in 1958, 25 firms produced 1,250,000, despite the phenomenal sale of refrigerating window air conditioners. Though clearly secondary to refrigeration, evaporative cooling is 60 to 80 percent is economical for moderate income groups and cheaper to buy and operate. Thus, it climates where summers are short. Moreover, it cheaply cools hot, thinly constructed mills, factories, workshops, foundries, powerhouses, farm buildings, canneries, etc., where refrigerated cooling is prohibitively expensive.

* A broad range of disciplines--energy conservation and air quality issues, construction and design, and the manufacture of temperature-sensitive products and materials--is covered in this comprehensive handbook * Provide essential, up-to-date HVAC data, codes, standards, and guidelines, all conveniently located in one volume * A definitive reference source on the design, selection and operation of A/C and refrigeration systems

"Under the right conditions and applications, evaporative air-conditioning (EAC) technologies can provide excellent cooling and ventilation with minimal energy consumption." Evaporative air-conditioning technologies are being used increasingly in residential and commercial applications worldwide. EAC technologies, which rely on water as a coolant rather than on chemical refrigerants, are economical to produce and use and have important environmental benefits. This paper introduces the technical aspects of EAC, reviews EAC's scope of application, and surveys the specific climatic conditions under which EAC can be used most effectively in industrialized and developing countries.

Air Conditioning with Natural Energy is a comprehensive examination of the principles, theory, applications, and energy saving performance of newly developed technologies for air conditioning using natural energy. Based on the latest research and real-world case studies from North America, Europe, and China, the book provides an engineering perspective on the design and application of air conditioning from multiple climates. The book is divided into two parts. Part I examines the range of air conditioning technologies that use natural energy. This includes enhanced treatment technologies for outdoor air such as earth-to-air heat exchanger, fresh air pre-handling system using shallow geothermal energy, as well as newly developed technologies such as pipe-embedded wall, nocturnal cooling wall, and pipe-embedded window systems. With particular focus on applications in China, Part II provides real world case studies from multiple climatic zones, demonstrating the practical application and implementation of these technologies. Each case study analyses the carbon emission reduction potential, energy saving potential and the operational performance of the technologies. Air Conditioning with Natural Energy is an invaluable review of the latest developments in air conditioning technologies for practicing engineers, researchers, and students involved in the design and implementation of HVAC systems or working in the fields of thermal and mechanical engineering and the sustainable built environment. - Explains the theory and principles underpinning the latest and most important air conditioning technologies with natural energy - Provides a new decision-making index and revised degree hours to evaluate the energy saving potential of different air conditioning technologies with natural energy, helping readers identify the most suitable air conditioning technology for any climate zone - Analyzes the energy saving potential of different technologies from real projects in different climate zones and calculates the contribution of carbon emission reduction that can be achieved globally

The role and influence of building services engineers are undergoing rapid change and are pivotal to achieving low-carbon buildings. However, textbooks in the field have tended to remain fairly traditional with a detailed focus on the technicalities of heating, ventilation and air conditioning (HVAC) systems, often with little wider context. This book addresses that need by embracing a contemporary understanding of the urgent challenge to address climate change, together with practical approaches to energy efficiency and carbon mitigation for mechanical and electrical systems, in a concise manner. The essential conceptual design issues for planning the principal building services systems that influence energy efficiency are examined in detail. These are HVAC and electrical systems. In addition, the following issues are addressed: background issues on climate change, whole-life performance and design collaboration generic strategies for energy efficient, low-carbon design health and wellbeing and post occupancy evaluation building ventilation air conditioning and HVAC system selection thermal energy generation and distribution systems low-energy approaches for thermal control electrical systems, data collection, controls and monitoring building thermal load assessment building electric power load assessment space planning and design integration with other disciplines. In order to deliver buildings that help mitigate climate change impacts, a new perspective is required for building services engineers, from the initial conceptual design and throughout the design collaboration with other disciplines. This book provides a contemporary introduction and guide to this new approach, for students and practitioners alike.
