There is widespread interest throughout the world in improving appliance energy efficiency. Methods to reach that end include energy labeling, energy efficiency standards and market conditioning (e.g, energy efficient procurement and DSM programs). Energy efficiency standards, which started out as an action to reduce demand for energy in individual countries, has now become a subject of regional and even worldwide dimension, particularly in the context of global climate change mitigation. Mandatory energy efficiency standards are in place for some appliances in China, Canada, Mexico, the Philippines and the United States. Standards for refrigerator/freezers will take effect in Australia and the European Union in 1999. Voluntary energy efficiency standards are in place for refrigerators in Brazil, India and Korea and for air conditioners in India, Japan and Korea. Table I showed potential global energy use reductions from codes and standards in buildings. If individual country data can be assembled, a more accurate approach to estimating potential reductions in energy use and carbon emissions would be to perform a bottom-up analysis for energy using equipment on an end-use basis in as many large developing countries as possible. The impact of standards would be assessed as more efficient appliances replaced existing stock models and new purchases that increased saturation rates were made at higher efficiencies than would otherwise be the case. This approach would show the slow but steady buildup of annual energy savings from efficiency standards or other programs to improve energy efficiency.

Direct Energy Conversion (Hardcover, New): Reiner Decher Direct Energy Conversion (Hardcover, New)
Reiner Decher
R7,811 Discovery Miles 78 110 Ships in 10 - 15 working days

Direct Energy Conversion is written for students and practicing engineers with an interest in the performance of energy conversion processes that involve direct methods of producing electric power from heat and other primary sources. It provides an in-depth development of key issues from the first principles of the underlying sciences, and examines the means available for converting heat to electricity without the intermediate generation of rotating shaft power. A physical and quantitative understanding of the limitations of a number of commercially interesting methods is developed in order to allow readers assessment of the technologies for specific applications. The list of processes considered is limited by performance measured in terms of cost, conversion efficiency, and power density. Ideal for senior undergraduate and graduate level courses in power production, energy conversion, and power systems, Direct Energy Conversion is also a natural adjunct to the author's previous text, Energy Conversion (OUP, 1994), which focuses on the thermodynamics and mechanics of heat.

Lord Kelvin (William Thomson), arguably Britain's most eminent scientist after Newton, spent much of his life in work which led to the development of today's electrical units and standards. Despite his influence, there are few biographies of stature (largely due to the abstruse nature of much of his technical research). This treatment concentrates upon his work in three phases; discovery of the fundamental concepts and coding them into universal laws, leading the adoption of the metric system, and securing worldwide use of units and standards (now the IEC system).

R3,756 R3,386 Discovery Miles 33 860 Save R370 (10%) Ships in 10 - 15 working days

This book aims at a theoretical and practical treatment of both conduction and induction heating. They share a common theory, one being the 'mirror image' of the other, and so one gets two for the price of one. The book comprises four parts: conduction theory, induction theory, heat flow and practice. Modern induction practice is treated in four big chapters - through heating, surface heating, special applications and metal melting. In addition, there is a smaller chapter on conduction heating. Although, at first sight, this might seem a lot of theory, the practical chapters make up half of the book and the theory itself is practically oriented. Throughout, the emphasis is on fundamentals and understanding, usually starting from first principles, with plenty of worked examples. Much of the theory is new, being either presented differently or solving new problems. Most of the Direct Resistance Heating is new. There are new approaches to tube heating, both for DRH and induction; these show clearly the relationship to the solid solution. There are also chapters on saturation and the effect of permeability. This is a book that should be invaluable to engineers and technicians, designers and users. It will be useful to students studying either the theory of the heating process or its practice. The mathematics is not difficult and SI units are used throughout.

This book offers a broad coverage of the theory and practice of industrial microwave heating. It introduces the physical processes behind dipolar and conductivity loss mechanisms and follows with a thorough presentation of dielectric property data of many industrial materials as a function of the moisture content, temperature and frequency, focussing on the interpretation of such data as regards the suitabiliy for processing these materials with microwave energy. The basic equations which govern the power dissipation, attenuation, phase constant, penetration depth and skin depth are derived from first principles while the transport equations of heat, mass and pressure are qualitatively described, giving particular emphasis to the physical mechanisms behind high frequency drying. The book provides established procedures backed by theoretical formulations for the design of industrial travelling wave and multimode applicators. It also provides extensive coverage of single mode fundamental or higher order resonant cavities and outlines a number of atypical applicator structures. It describes the essential features of processing with microwaves under vacuum and presents a brief introduction to the mechanisms which lead to gas breakdown. It stresses the need for a degree of hybridisation with other electrical or conventional heating systems and discusses a few such schemes. The book outlines a number of systems for limiting leakage from on-line industrial microwave systems and concludes with an extensive discussion of successful industrial applications.

Wireless Power Transfer (WPT) enables power to be transferred from a grid or storage unit to a device without the need for cable connections. This can be performed by inductive coupling of magnetic fields as well as by direct radiative transfer via beams of electromagnetic waves, commonly radiowaves, microwaves or lasers. Inductive coupling is the most widely used wireless technology with applications including charging handheld devices, RFID tags, chargers for implantable medical devices, and proposed systems for charging electric vehicles. Applications of radiative power transfer include solar power satellites and wireless powered drone aircraft. This book covers the very latest in theory and technology of both coupling and radiative wireless power transfer. Topics covered include the basic theory of inductive coupling and resonance coupling WPT; multi-hop WPT; circuit theory for wireless couplers; inverter/ rectifier technologies for WPT systems; basic theory of WPT via radio waves; technologies of antenna and phased array for WPT via radio waves; transmitter/rectifier technologies for WPT via radio waves; applications of coupling WPT for electric vehicle charging; applications of long-distance WPT; and biological interactions of electromagnetic fields and waves.

Electrifying America - Social Meanings of a New Technology, 1880-1940 (Paperback, New Ed): David E Nye Electrifying America - Social Meanings of a New Technology, 1880-1940 (Paperback, New Ed)
David E Nye
R1,849 Discovery Miles 18 490 Ships in 10 - 15 working days

How did electricity enter everyday life in America? Using Muncie, Indiana - the Lynds' now iconic Middletown - as a touchstone, David Nye explores how electricity seeped into and redefined American culture. With an eye for telling details from archival sources and a broad understanding of cultural and social history, he creates a thought-provoking panorama of a technology fundamental to modern life.Emphasizing the experiences of ordinary men and women rather than the lives of inventors and entrepreneurs, Nye treats electrification as a set of technical possibilities that were selectively adopted to create the streetcar suburb, the amusement park, the "Great White Way," the assembly line, the electrified home, and the industrialized farm. He shows how electricity touched every part of American life, how it became an extension of political ideologies, how it virtually created the image of the modern city, and how it even pervaded colloquial speech, confirming the values of high energy and speed that have become hallmarks of the twentieth century. He also pursues the social meaning of electrification as expressed in utopian ideas and exhibits at world's fairs, and explores the evocation of electrical landscapes in painting, literature, and photography.Electrifying America combines chronology and topicality to examine the major forms of light and power as they came into general use. It shows that in the city electrification promoted a more varied landscape and made possible new art forms and new consumption environments. In the factory, electricity permitted a complete redesign of the size and scale of operations, shifting power away from the shop floor to managers. Electrical appliances redefined domestic work and transformed the landscape of the home, while on the farm electricity laid the foundation for today's agribusiness.David E. Nye teaches American history at the University of Copenhagen. He has published books on Henry Ford and Thomas Edison, as well as Image Worlds, a study of photography and corporate identities at General Electric.
