Available in PDF, EPUB and Kindle. Book excerpt: This book describes fluorocarbons gases’ preparation process, properties, applications and their evolution over time. The impact of fluorocarbons on the ozone layer and global and the development to mitigate those effects have been specially emphasized. The first major industrial fluorinated compound was developed in the 1920’s, to replace ammonia and sulfur dioxide refrigerants, at the General Motors Frigidaire Division by Thomas Midgley, Jr. and Albert Leon Henne. They developed a family of fluorocarbons trademarked Freon® for auto air conditioning units revolutionizing the auto industry. Other applications were developed over time including fire extinguishers, propellants, blowing agents, cleaners, anesthesia, artificial blood and others impacting every facet of life. In spite of being in broad global use for nearly a century, fluorocarbon gases have gone through great evolution during the last few decades. In the 1980s it was discovered chlorofluorocarbon (CFC) gases are harmful to the ozone layer, mainly because of their chlorine content. Chlorine was released in the upper atmosphere when chlorofluorocarbon molecules were broken down by the high energy cosmic radiation. CFCs were progressively banned following the Montreal Protocol of 1987. CFCs were replaced by fluorinated gases containing either less chlorine (hydrofluoro-chlorocarbons, or HCFCs), which are much less damaging (about 90% less) to the ozone layer or with fluorinated gases containing no chlorine, i.e. hydrofluorocarbons or HFCs. HFC have no impact on the ozone layer but impact global warming detrimentally. HFCs are usable without need for changes to the existing refrigeration or air conditioning installations. More recently hydrofluoroolefins (HFOs), which have little or no negative impact on global warming, have been developed to replace or reduce the use of HFCs. HFOs are used as single compounds or in blends. Research and development continues to develop and replace the HCFCs and HFCs completely with environmentally friendly products. Concise Handbook of Fluorocarbon Gases presents a reference and text for the commercial fluorocarbon gases which have great many application in a wide range of industries such as refrigeration and air conditioning, as well as consumer products.

Book excerpt: From a late-night snack to a cold beer, there’s nothing that whets the appetite quite like the suctioning sound of a refrigerator being opened. In the early 1930s fewer than ten percent of US households had a mechanical refrigerator, but today they are nearly universal, the primary means by which we keep our food and drink fresh. Yet, for as ubiquitous as refrigerators are, most of us take them for granted, letting them blend into the background of our kitchens, basements, garages, and all the other places where they seem so perfectly convenient. In this book, Helen Peavitt amplifies the hum of the refrigerator in technological history, showing us just how it became such an essential appliance. Peavitt takes us to the early closets, cabinets, and boxes into which we first started packing ice and the various things we were trying to keep cool. From there she charts the development of mechanical and chemical technologies that have led to modern-day refrigeration on both industrial and domestic scales, showing how these technologies have created a completely new method of preserving and transporting perishable goods, having a profound impact on society from the nineteenth century and on. She explores the ways the marketing of refrigerators have expressed and influenced our notions of domestic life, and she looks at how refrigeration has altered the agriculture and food industries as well as our own appetites. Strikingly illustrated, this book offers an informative and entertaining history of an object that has radically changed—in a little over one hundred years—one of the most important things we do: eat.
