How Do Refrigerators Work?


Book Description

Looks into the science behind refrigerators and the reasons for their popularity, including their history and the ways they have changed over the years.




Chilled


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.




Before the Refrigerator


Book Description

A historical study of how increased access to ice—decades before refrigeration—transformed American life. During the late nineteenth and early twentieth centuries, Americans depended upon ice to stay cool and to keep their perishable foods fresh. Jonathan Rees tells the fascinating story of how people got ice before mechanical refrigeration came to the household. Drawing on newspapers, trade journals, and household advice books, Before the Refrigerator explains how Americans built a complex system to harvest, store, and transport ice to everyone who wanted it, even the very poor. Rees traces the evolution of the natural ice industry from its mechanization in the 1880s through its gradual collapse, which started after World War I. Meatpackers began experimenting with ice refrigeration to ship their products as early as the 1860s. Starting around 1890, large, bulky ice machines the size of small houses appeared on the scene, becoming an important source for the American ice supply. As ice machines shrunk, more people had access to better ice for a wide variety of purposes. By the early twentieth century, Rees writes, ice had become an essential tool for preserving perishable foods of all kinds, transforming what most people ate and drank every day. Reviewing all the inventions that made the ice industry possible and the way they worked together to prevent ice from melting, Rees demonstrates how technological systems can operate without a central controlling force. Before the Refrigerator is ideal for history of technology classes, food studies classes, or anyone interested in what daily life in the United States was like between 1880 and 1930. “An in-depth portrayal of a once-indispensable, life-changing technology, the former existence of which is as unknown to most of us as that of the telegraph or canal is to today’s undergraduates. . . . Rees synthesizes considerable archival research and presents interpretations of importance to scholars. . . . Before the Refrigerator is as refreshing as ice water on a hot summer day.” —Journal of American History “This fact-filled book explains how ice became an American necessity by the early twentieth century. Students in business history and history of technology courses will be fascinated to learn how macrobreweries made lager into America’s favorite beer, how cocktails became commonplace, and how burly men used to lug giant blocks of ice into American kitchens.” —Shane Hamilton, author of Trucking Country: The Road to America’s Wal-Mart Economy

Refrigeration Nation


Book Description

How we keep food cold while the house stays warm. Only when the power goes off and food spoils do we truly appreciate how much we rely on refrigerators and freezers. In Refrigeration Nation, Jonathan Rees explores the innovative methods and gadgets that Americans have invented to keep perishable food cold—from cutting river and lake ice and shipping it to consumers for use in their iceboxes to the development of electrically powered equipment that ushered in a new age of convenience and health. As much a history of successful business practices as a history of technology, this book illustrates how refrigeration has changed the everyday lives of Americans and why it remains so important today. Beginning with the natural ice industry in 1806, Rees considers a variety of factors that drove the industry, including the point and product of consumption, issues of transportation, and technological advances. Rees also shows that how we obtain and preserve perishable food is related to our changing relationship with the natural world.




Refrigeration


Book Description

For thousands of years, humans coped with heat by harvesting and storing natural ice and devising natural cooling systems that utilized ventilation and evaporation. By the mid 1800s, people began developing huge refrigeration machines to manufacture ice. By the early 1900s, engineers developed electric domestic refrigerators, which by 1927 were affordable convenient household appliances. By then, an increasingly sophisticated public demanded more modern-looking appliances than engineers could produce, and a new breed of designers entered the manufacturing world to provide them. During the Depression, modern designs not only increased sales but resulted in the kitchen appliances we now use. Today refrigeration preserves perishable food for worldwide distribution, makes tropical climates habitable for millions, saves lives with medical applications and enables space flight.
