This “ambitious [and] delightful” (The New York Times) work of literary nonfiction interweaves the science and history of the powerful refrigerant (and dangerous greenhouse gas) Freon with a haunting meditation on how to live meaningfully and morally in a rapidly heating world. In After Cooling, Eric Dean Wilson braids together air-conditioning history, climate science, road trips, and philosophy to tell the story of the birth, life, and afterlife of Freon, the refrigerant that ripped a hole larger than the continental United States in the ozone layer. As he traces the refrigerant’s life span from its invention in the 1920s—when it was hailed as a miracle of scientific progress—to efforts in the 1980s to ban the chemical (and the resulting political backlash), Wilson finds himself on a journey through the American heartland, trailing a man who buys up old tanks of Freon stockpiled in attics and basements to destroy what remains of the chemical before it can do further harm. Wilson is at heart an essayist, looking far and wide to tease out what particular forces in American culture—in capitalism, in systemic racism, in our values—combined to lead us into the Freon crisis and then out. “Meticulously researched and engagingly written” (Amitav Ghosh), this “knockout debut” (New York Journal of Books) offers a rare glimpse of environmental hope, suggesting that maybe the vast and terrifying problem of global warming is not beyond our grasp to face.

NEW YORK TIMES BESTSELLER For the first time ever, an international coalition of leading researchers, scientists and policymakers has come together to offer a set of realistic and bold solutions to climate change. All of the techniques described here - some well-known, some you may have never heard of - are economically viable, and communities throughout the world are already enacting them. From revolutionizing how we produce and consume food to educating girls in lower-income countries, these are all solutions which, if deployed collectively on a global scale over the next thirty years, could not just slow the earth's warming, but reach drawdown: the point when greenhouse gasses in the atmosphere peak and begin todecline. So what are we waiting for?

Fishing vessels can be equipped with energy efficient refrigeration technology applying natural working fluids. Ammonia refrigeration systems have been the first choice, but CO2 units have also become increasingly common in the maritime sector in the last few years. When retrofitting or implementing CO2 refrigeration plants, less space on board is required and such units allow good service and maintenance. Nowadays, cruise ship owners prefer CO2 units for the provision refrigeration plants.Ship owners, responsible for the health and safety of the crew and passengers, must carefully evaluate the usage of flammable low GWP working fluids, due to a high risk that toxic decomposition products are formed, even without the presence of an open flame. Suggestions for further work include a Nordic Technology Hub for global marine refrigeration R&D and development support for key components.

The definitive text/reference for students, researchers and practicing engineers This book provides comprehensive coverage on refrigeration systems and applications, ranging from the fundamental principles of thermodynamics to food cooling applications for a wide range of sectoral utilizations. Energy and exergy analyses as well as performance assessments through energy and exergy efficiencies and energetic and exergetic coefficients of performance are explored, and numerous analysis techniques, models, correlations and procedures are introduced with examples and case studies. There are specific sections allocated to environmental impact assessment and sustainable development studies. Also featured are discussions of important recent developments in the field, including those stemming from the author’s pioneering research. Refrigeration is a uniquely positioned multi-disciplinary field encompassing mechanical, chemical, industrial and food engineering, as well as chemistry. Its wide-ranging applications mean that the industry plays a key role in national and international economies. And it continues to be an area of active research, much of it focusing on making the technology as environmentally friendly and sustainable as possible without compromising cost efficiency and effectiveness. This substantially updated and revised edition of the classic text/reference now features two new chapters devoted to renewable-energy-based integrated refrigeration systems and environmental impact/sustainability assessment. All examples and chapter-end problems have been updated as have conversion factors and the thermophysical properties of an array of materials. Provides a solid foundation in the fundamental principles and the practical applications of refrigeration technologies Examines fundamental aspects of thermodynamics, refrigerants, as well as energy and exergy analyses and energy and exergy based performance assessment criteria and approaches Introduces environmental impact assessment methods and sustainability evaluation of refrigeration systems and applications Covers basic and advanced (and hence integrated) refrigeration cycles and systems, as well as a range of novel applications Discusses crucial industrial, technical and operational problems, as well as new performance improvement techniques and tools for better design and analysis Features clear explanations, numerous chapter-end problems and worked-out examples Refrigeration Systems and Applications, Third Edition is an indispensable working resource for researchers and practitioners in the areas of Refrigeration and Air Conditioning.

Master's Thesis from the year 2019 in the subject Engineering - Power Engineering, , language: English, abstract: World population has reached 7 billion people in 2013 and there has been an increase in energy consumption, especially in emerging countries. In 2050 it will be more than 9 billion people living on the planet. Because of this, there has been a rapid increase in CO2 concentration levels, so the average planet temperature is rising, causing a greenhouse effect, as the CO2 is trapping in the heat and not releasing it. Consequently, ocean levels are rising, because of the shrinking polar ice caps. We also have seen an increase in the frequency of extreme atmosphere events around the globe. The refrigeration industry has contributed a lot to the global ozone depletion and global warming. To reduce the environmental impact by the heating, ventilation, air conditioning and refrigeration industry – both commercial and domestic – there is an urgent need to look for solutions that are both ozone friendly and CO2 friendly (greenhouse effect friendly). Eradicating the damage to the environment has encouraged the industrial and commercial refrigeration industry to investigate refrigerant alternatives that reduce the environmental impact although a good transition to them will also depend on the training that technicians acquire, as well as the understanding of the current and future benefits for the companies and the end users. This thesis aims at such a system which is both above mentioned. Once such a system is designed, it is of the utmost importance to test it and compare it with the systems that are being used currently to assess the benefits of using such system. The thesis has a focus on the liquid cooling systems such as water coolers and small commercial systems that help attain cooling of the liquids to a set temperature. In this thesis, the improvement of energy consumption and environmental degradation prevention is attained by switching the refrigerant used from R134a (current) to R290 (Propane) which is a natural refrigerant and Hydro Carbon Blend which is a mixture of refrigerants but is safer and environmentally friendlier. A comparison of both systems is done against the current system in terms of efficiency, energy consumption and chemical properties with respect to global warming potential and ozone depletion potential and ultimately proven that natural refrigerants and HC Blends are the refrigerants of the future.
