Many laboratories are engaged in research on the development of new fluids for use as refrigerants to replace the fully halogenated materials that are believed to contribute to atmospheric ozone depletion. An integral part of this effort is the chemical analysis of new fluids that are synthesized, prepared, and tested. This comprehensive book, which is divided into two parts, fills an important need in this vital chemical analysis protocol. The first part reviews the major chemical analysis methods that have been developed and used at NIST and in other laboratories. This review covers spectroscopic, chromatographic, and "wet" analytical methods, with treatment divided by qualitative identification, qualitative determinations, and chemical reaction screening. The second part contains a compilation of analytical information of the new fluids and their products. Physical properties, mass spectra, infrared spectra, ultraviolet spectra, nuclear magnetic resonance spectra, and gas chromatographic retention data are provided for each fluid or product.
• New York Times bestseller • The 100 most substantive solutions to reverse global warming, based on meticulous research by leading scientists and policymakers around the world “At this point in time, the Drawdown book is exactly what is needed; a credible, conservative solution-by-solution narrative that we can do it. Reading it is an effective inoculation against the widespread perception of doom that humanity cannot and will not solve the climate crisis. Reported by-effects include increased determination and a sense of grounded hope.” —Per Espen Stoknes, Author, What We Think About When We Try Not To Think About Global Warming “There’s been no real way for ordinary people to get an understanding of what they can do and what impact it can have. There remains no single, comprehensive, reliable compendium of carbon-reduction solutions across sectors. At least until now. . . . The public is hungry for this kind of practical wisdom.” —David Roberts, Vox “This is the ideal environmental sciences textbook—only it is too interesting and inspiring to be called a textbook.” —Peter Kareiva, Director of the Institute of the Environment and Sustainability, UCLA In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.
Highlights the issues related to ozone layer depletion and global warming due to use of conventional cooling technologies and refrigerants in the field of Refrigeration and Air Conditioning (RAC). It describes, simulates and analyses the alternate technologies and alternate refrigerants. Unconventional refrigeration technologies are explored.
Two-Phase Flow in Refrigeration Systems presents recent developments from the authors' extensive research programs on two-phase flow in refrigeration systems. This book covers advanced mass and heat transfer and vapor compression refrigeration systems and shows how the performance of an automotive air-conditioning system is affected through results obtained experimentally and theoretically, specifically with consideration of two-phase flow and oil concentration. The book is ideal for university postgraduate students as a textbook, researchers and professors as an academic reference book, and by engineers and designers as handbook.
