Book Description
• New York Times bestseller • The 100 most substantive solutions to reverse global warming, based on meticulous research by leading scientists and policymakers around the world “At this point in time, the Drawdown book is exactly what is needed; a credible, conservative solution-by-solution narrative that we can do it. Reading it is an effective inoculation against the widespread perception of doom that humanity cannot and will not solve the climate crisis. Reported by-effects include increased determination and a sense of grounded hope.” —Per Espen Stoknes, Author, What We Think About When We Try Not To Think About Global Warming “There’s been no real way for ordinary people to get an understanding of what they can do and what impact it can have. There remains no single, comprehensive, reliable compendium of carbon-reduction solutions across sectors. At least until now. . . . The public is hungry for this kind of practical wisdom.” —David Roberts, Vox “This is the ideal environmental sciences textbook—only it is too interesting and inspiring to be called a textbook.” —Peter Kareiva, Director of the Institute of the Environment and Sustainability, UCLA In the face of widespread fear and apathy, an international coalition of researchers, professionals, and scientists have come together to offer a set of realistic and bold solutions to climate change. One hundred techniques and practices are described here—some are well known; some you may have never heard of. They range from clean energy to educating girls in lower-income countries to land use practices that pull carbon out of the air. The solutions exist, are economically viable, and communities throughout the world are currently enacting them with skill and determination. If deployed collectively on a global scale over the next thirty years, they represent a credible path forward, not just to slow the earth’s warming but to reach drawdown, that point in time when greenhouse gases in the atmosphere peak and begin to decline. These measures promise cascading benefits to human health, security, prosperity, and well-being—giving us every reason to see this planetary crisis as an opportunity to create a just and livable world.

Book Description
Refrigeration, air conditioning, and heat pumps (RACHP) have an important impact on the final energy uses of many sectors of modern society, such as residential, commercial, industrial, transport, and automotive. Moreover, RACHP also have an important environmental impact due to the working fluids that deplete the stratospheric ozone layer, which are being phased out according to the Montreal Protocol (1989). Last, but not least, high global working potential (GWP), working fluids (directly), and energy consumption (indirectly) are responsible for a non-negligible quota of greenhouse gas (GHG) emissions in the atmosphere, thus impacting climate change.

Book Description
Abstract: The evolution, trends, and applications of the mechanical aspects of refrigeration are traced from 1755 to the present day. The information is intended to appeal not only to engineering students and refrigerationists, but to the general reader as well. The history is divided into 4 epochs. The first, before 1875, discusses natural refrigeration, thermometry, the development of the concepts of heat and thermal processes, and the 4 families of refrigerating machines. The second epoch, 1875-1914, covers the industrialization of refrigeration and its first applications to brewing, food preservation, storage and transport, and non-food applications such as air conditioning and cryogenics. The third epoch, between the wars, introduces the compressor, refrigeration in daily life, and further developments in established areas. The final epoch, after 1945, documents the explosion of refrigeration technology, its spread throughout the world, and its thousands of uses, from desalination of sea water tofreeze-dried foodstuffs and medical applications.

Book Description
Losing our Cool shows how indoor climate control is colliding with an out-of-control outdoor climate. In America, energy consumed by home air-conditioning, and the resulting greenhouse emissions, have doubled in just over a decade, and energy to cool retail stores has risen by two-thirds. Now the entire affluent world is adopting the technology. As the biggest economic crisis in eighty years rolls across the globe, financial concerns threaten to shove ecological crises into the background. Reporting from some of the world's hot zones—from Phoenix, Arizona, and Naples, Florida, to southern India—Cox documents the surprising ways in which air-conditioning changes human experience: giving a boost to the global warming that it is designed to help us endure, providing a potent commercial stimulant, making possible an impossible commuter economy, and altering migration patterns (air-conditioning has helped alter the political hue of the United States by enabling a population boom in the red-state Sun Belt). While the book proves that the planet's atmosphere cannot sustain even our current use of air-conditioning, it also makes a much more positive argument that loosening our attachment to refrigerated air could bring benefits to humans and the planet that go well beyond averting a climate crisis. Though it saves lives in heat waves, air-conditioning may also be altering our bodies' sensitivity to heat; our rates of infection, allergy, asthma, and obesity; and even our sex drive. Air-conditioning has eroded social bonds and thwarted childhood adventure; it has transformed the ways we eat, sleep, travel, work, buy, relax, vote, and make both love and war. The final chapter surveys the many alternatives to conventional central air-conditioning. By reintroducing some traditional cooling methods, putting newly emerging technologies into practice, and getting beyond industrial definitions of comfort, we can make ourselves comfortable and keep the planet comfortable, too.

Book Description
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.

Book Description
Air conditioning system is one of the major consumers of electrical energy in many parts of the world today. It represents between 40 and 70% of the energy consumption in commercial buildings. The demand of energy for air conditioning systems is expected to increase further in the next decades due to the population growth, the new economic boom, and the urbanization development. The rapid growth of air conditioning and electricity consumption will contribute further to climate change if fossil and nonrenewable resources are used. More energy-efficient and renewable energy-based air conditioning systems to accomplish space cooling are needed. This book intends to provide the reader with a comprehensive overview of the current state of the art in sustainable air conditioning technologies and focus on the most recent research and development on green air conditioning systems including energy-efficient and renewable energy-based air conditioning systems.
