Refrigeration is an amazing area where science and engineering meet for solving the humankind’s cooling and refrigeration needs in an extensive range of applications, ranging from the cooling of electronic devices to food cooling, and has a multidisciplinary character, involving a combination of several disciplines, including mechanical engineering, chemical engineering, chemistry, food engineering, civil engineering and many more. The refrigeration industry has drastically expanded during the past two decades to play a significant role in societies and their economies. Therefore, the economic impact of refrigeration technology throughout the world has become more impressive and will continue to become even more impressive in the future because of the increasing demand for refrigeration systems and applications. Of course, this technology serves to improve living conditions in countless ways. This second edition of the book has improved and enhanced contents in several topics, particularly in advanced refrigeration systems. It now includes study problems and questions at the end of each chapter, which makes the book appropriate as a textbook for students and researchers in academia. More importantly, it now has comprehensive energy and exergy analyses presented in several chapters for better and performance improvement of refrigeration systems and applications, which make it even more suitable for industry. Coverage of the material is extensive, and the amount of information and data presented is sufficient for several courses if studied in detail. It is strongly believed that the book will be of interest to students, refrigeration engineers, practitioners, and producers, as well as people and institutions that are interested in refrigeration systems and applications, and that it is also a valuable and readable reference text and source for anyone who wishes to learn more about refrigeration systems and applications and their and analysis.
Chapter 1 addresses general concepts, fundamental principles, and basic aspects of thermodynamics, psychrometrics, fluid flow and heat transfer with a broad coverage to furnish the reader with background information that is relevant to the analysis of refrigeration systems and applications. Chapter 2 provides useful information on several types of refrigerants and their environmental impact, as well as their thermodynamic properties. Chapter 3 delves into the specifics of refrigeration system components and their operating and technical aspects, analysis details, utilization perspectives and so on, before getting into refrigeration cycles and systems. Chapter 4 presents a comprehensive coverage on refrigeration cycles and systems for various applications, along with their energy and exergy analyses. Chapter 5 as a new chapter provides enormous material on advanced refrigeration cycles and systems for numerous applications with operational and technical details. There are also illustrative examples of system analyses through energy and energy, which make it unique in this book. Chapter 6 deals with a number of technical aspects related to heat pump systems and applications, energy and exergy analyses and performance evaluation of heat pump systems, new heat pump applications and their utilization in industry, and ground source heat pump systems and applications. Chapter 7 is about heat pipes and their micro- and macro-scale applications, technical, design, manufacturing, and operational aspects of heat pipes, heat pipe utilization in HVAC applications, and their performance evaluation. Incorporated through this book are many wide-ranging examples which provide useful information for practical applications. Conversion factors and thermophysical properties of various materials, as well as a large number of food refrigeration data, are listed in the appendices in the International System of Units (SI).
