Book Description
Progress in Refrigeration Science and Technology, Volume II is a collection of papers from the Eleventh International Congress of Refrigeration held in Munich in August-September 1963. These papers deal with the various scientific and technical aspects, designs, and technology of refrigeration used in food, as well as advances in air-conditioning, and heat pumps. One paper discusses the refrigeration of meat, fruit, or vegetables, and the reaction rate of proteolysis in low temperatures. The paper points out that meat preservation by freezing is not economical below 60 degrees centigrade citing the reason that cathepsines are still catalytically active in lower temperatures. Other papers discuss the effects of freezing of beef, pork, turkey, chicken, sweet corn, spinach puree. As regards fruit and vegetable storage, the air needs to be purified to inhibit infections, retard fungal or bacterial growth, and dissipate ripening gases or foul odors. Another paper examines the reasons for doing away with floor insulation in refrigeration plants used in storing fresh meat during the summer and winter months. This collection is suitable for engineers in the area of refrigeration, and also for food technologists involved in food research and preservation.

Book Description
Refrigeration is the process of removing heat from an enclosed space, or from a substance, and moving it to a place where it is unobjectionable. The primary purpose of refrigeration is lowering the temperature of the enclosed space or substance and then maintaining that lower temperature. This book reviews research on refrigeration including an overview of up-to-date developments and technology in the field of magnetic refrigeration at room temperature (RTMR); an alternative approach based on artificial neural networks (ANNs) to determine thermodynamic properties of refrigerants; solar powered sorption refrigeration and air conditioning; the modelling of chilling and freezing processes and others.

Book Description
A thrilling, mystery-lifting narrative history of the refrigerator and the process of refrigeration The refrigerator. This white box that sits in the kitchen may seem mundane nowadays, but it is one of the wonders of 20th century science – life-saver, food-preserver and social liberator, while the science of refrigeration is crucial, not just in transporting food around the globe but in a host of branches on the scientific tree. Refrigerators, refrigeration and its discovery and applications provide the eye-opening backdrop to Chilled, the story of how science managed to rewrite the rules of food, and how the technology whirring behind every refrigerator is at play, unseen, in a surprisingly broad sweep of modern life. Part historical narrative, part scientific mystery-lifter, Chilled looks at the ice-pits of Persia (Iranians still call their fridge the 'ice-pit'), reports on a tug of war between 16 horses and the atmosphere, bears witness to ice harvests on the Regents Canal, and shows how bleeding sailors demonstrated to ship's doctors that heat is indestructible, featuring a cast of characters such as the Ice King of Boston, Galileo, Francis Bacon, and the ostracised son of a notorious 18th-century French traitor. As people learned more about what cold actually was, scientists invented machines for making it, with these first used in earnest to chill Australian lager. The principles behind those white boxes in the kitchen remain the same today, but refrigeration is not all about food – a refrigerator is needed to make soap, penicillin and orange squash; without it, IVF would be impossible. Refrigeration technology has also been crucial in some of the most important scientific breakthroughs of the last 100 years, from the discovery of superconductors to the search for the Higgs boson. And the fridge will still be pulling the strings behind the scenes as teleporters and intelligent computer brains turn our science-fiction vision of the future into fact.

Book Description
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.
