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.

The food service industry is plagued by under-trained technical service personnel. Since ice is food it is essential for service workers, technicians and health inspectors to upskill beyond their current competencies. Finally, a reference book that speaks only to commercial ice machines is available for training of technicians in a manner that helps to ensure the quality of the food chain. Long before the factory service manuals are of use, the fundamentals aspects of the ice machine must be learned. -The types of ice found in the commercial food service industry -Practical troubleshooting -Introductions to ice machine specific refrigeration and electrical components -Sequences of operation -Increase health code compliance and inspector confidence -150+ color photographs of real world parts and installation This book is most suited for: -Equipment Owners -Health Inspectors -Facility Manager -HVAC or Refrigeration Technicians -Appliance Repair Technicians -Service Managers -Energy Auditors -Vocational Schools -Community College Students -Ice Machine Factory Training Department Written by a Certified Master HVAC/R Educator and contractor, the skills outlined in this book are invaluable to anyone involved in the maintenance and service of ice machines. If you need to buy commercial ice machines, then approach the purchase with the confidence of knowing more than most sellers.
