Refrigeration nation : a history of ice, appliances, and enterprise in America
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.

Frostbite : how refrigeration changed our food, our planet, and ourselves
\"An engaging and far-reaching exploration of refrigeration, tracing its evolution from scientific mystery to globe-spanning infrastructure, and an essential investigation into how it has remade our entire relationship with food-for better and for worse. How often do we open the fridge or peer into the freezer with the expectation that we'll find something fresh and ready to eat? It's an everyday act, easily taken for granted, but just a century ago, eating food that had been refrigerated was cause for both fear and excitement. Banquets were held just so guests could enjoy the novelty of eggs, butter, and apples that had been preserved for months in cold storage-and demonstrate that such zombie foods were not deadly. The introduction of artificial refrigeration overturned millennia of dietary history, launching an entirely new chapter in human nutrition. We could now overcome not just rot, but also seasonality and geography. Tomatoes in January? Avocados in Shanghai? All possible. In FROSTBITE, New Yorker contributor and co-host of the award-winning podcast Gastropod Nicola Twilley takes readers with her on a tour of the cold chain from farm to fridge, visiting such off-the-beaten-track landmarks as Missouri's subterranean cheese caves, the banana-ripening rooms of New York City, and the vast refrigerated tanks that store the nation's OJ reserves. Today, more than three-quarters of everything on the average American plate is processed, shipped, stored, and sold under refrigeration. It's impossible to make sense of our food system without understanding the all-but-invisible network of thermal control that underpins it. Twilley's eye-opening book is the first to reveal the transformative impact refrigeration has had on our health and our guts; our farms, tables, kitchens, and cities; global economics and politics; and even our environment. In the developed world, we've reaped the benefits of refrigeration for more than a century, but as Twilley soon discovers, the costs are catching up with us. We've eroded our connection to our food, extending the distance between producers and consumers and redefining what \"fresh\" really means. More importantly, refrigeration is one of the leading contributors to climate change. As the developing world races to build a U.S.-style cold chain, Twilley asks, can we reduce our dependence on refrigeration? Should we? A deeply-researched and reported, original, and entertaining dive into the most important invention in the history of food and drink, FROSTBITE makes the case for a recalibration of our relationship with the fridge-and how our future might depend on it\"-- Provided by publisher.

Industry Roundup
IIAR Developing Safety Guidance For CO2 Refrigeration ALEXANDRIA, Va.-The International Institute of Ammonia Refrigeration (IIAR) says it is developing a standard for CO2 that will specify criteria for the safe design and operation of CO2 refrigeration systems such as cascade and transcritical. By leveraging the store's existing refrigeration system, the product stores \"cooling\" at night by freezing tanks of salt water when energy costs are low.

Magnetic Refrigeration Design Technologies: State of the Art and General Perspectives
Magnetic refrigeration is a fascinating superior choice technology as compared with traditional refrigeration that relies on a unique property of particular materials, known as the magnetocaloric effect (MCE). This paper provides a thorough understanding of different magnetic refrigeration technologies using a variety of models to evaluate the coefficient of performance (COP) and specific cooling capacity outputs. Accordingly, magnetic refrigeration models are divided into four categories: rotating, reciprocating, C-shaped magnetic refrigeration, and active magnetic regenerator. The working principles of these models were described, and their outputs were extracted and compared. Furthermore, the influence of the magnetocaloric effect, the magnetization area, and the thermodynamic processes and cycles on the efficiency of magnetic refrigeration was investigated and discussed to achieve a maximum cooling capacity. The classes of magnetocaloric magnetic materials were summarized from previous studies and their potential magnetic characteristics are emphasized. The essential characteristics of magnetic refrigeration systems are highlighted to determine the significant advantages, difficulties, drawbacks, and feasibility analyses of these systems. Moreover, a cost analysis was provided in order to judge the feasibility of these systems for commercial use.

Ultra-Low-Temperature Refrigeration Systems: A Review and Performance Comparison of Refrigerants and Configurations
During the last decade, many industrial and medical applications have shown a requirement for low-temperature-cooling usage (from −40 to −80 °C), which cannot be efficiently obtained via the conventional refrigeration systems usually employed for medium-temperature applications (from 0 to −40 °C). A proper ultra-low-temperature (ULT) refrigeration system design is essential to achieve the desired output. The performance can be maximised via the suitable selection of the configuration and refrigerant for a specific temperature range. This work contributes a detailed overview of the different systems and refrigerants used in ultra-low-temperature applications. Different systems, such as single-stage vapour compression, multi-stage, cascade, auto-cascade, and air refrigeration cycles, are presented and discussed. An energy analysis is then carried out for these systems identifying the optimal system design and refrigerant selection to achieve the highest performance. This paper aims to provide the reader with a comprehensive background through an exhaustive review of refrigeration systems suitable for ultra-low-temperature applications. The effectiveness of these systems is proven numerically, mainly based on the temperature level and purpose of the application.
