Introduction To Refrigerating Engineering

This text provides background information, description, and analysis of four major cooling system technologies—vapor compression cooling, evaporative cooling, absorption cooling, and gas cooling. Vapor compression systems are currently the primary technology used in most standard domestic, commercial, and industrial cooling applications, as they have both performance and economic advantages over the other competing cooling systems. However, there are many other applications in which evaporative cooling, absorption cooling, or gas cooling technologies are a preferred choice. The main focus of the text is on the application of the thermal sciences to refrigeration and air conditioning systems. The goals are to familiarize the reader with cooling technology nomenclature, and provide insight into how refrigeration and air conditioning systems can be modeled and analyzed.Cooling systems are inherently complex, as the second law of thermodynamics does not allow thermal energy to be transferred directly from a lower temperature to a higher temperature, so the heat transfer is done indirectly through a thermodynamic cycle. Emphasis is placed on constructing idealized thermodynamic cycles to represent actual physical situations in cooling systems. The text also contains numerous practical examples to show how one can calculate the performance of cooling system components. By becoming familiar with the analyses presented in the examples, one can gain a feel for the the representative values of the various thermal and mechanical parameters that characterize cooling systems.

An air conditioning system consists of components and equipment arranged in sequential order to control and maintain an indoor environment. The goal is to provide a healthy and comfortable climate with acceptable air quality while being energy efficient and cost effective. Air Conditioning and Refrigeration Engineering covers all types of systems from institutional and commercial to residential. The book supplies the basics of design, from selecting the optimum system and equipment to preparing the drawings and specifications. It discusses the four phases of preparing a project: gathering information, developing alternatives, evaluating alternatives, and selling the best solution. In addition, the author breaks down the responsibilities of the engineer, design documents, computer aided design, and government codes and standards. Air Conditioning and Refrigeration Engineering provides you with an easy reference to all aspects of the topic. This resource addresses the most current areas of interest, such as computer-aided design and drafting, desiccant air conditioning and energy conservation. It is a thorough and convenient guide to air conditioning and refrigeration engineering.

This second edition builds on the foundation established by the previous first edition published in 2017. The first edition covered background information, description, and analysis of four major cooling system technologies - vapor compression cooling, evaporative cooling, absorption cooling, and gas cooling. The second edition has been expanded to include increased coverage of cooling system refrigerants, fluid mechanics, heat transfer, and building cooling loads. With increasing climate change due to the buildup of greenhouse gas emissions in the atmosphere, there has been a worldwide impetus to transition to cooling systems and refrigerants that have a low or even zero global warming potential. The text is written as a tutorial for engineering students and practicing engineers who want to become more familiar with the performance of refrigeration and air conditioning systems. The goals are to familiarize the reader with cooling technology nomenclature and provide insight into how refrigeration and air conditioning systems can be modeled and analyzed. Emphasis is placed on constructing idealized thermodynamic cycles to represent actual physical situations in cooling systems. The book contains numerous practical examples to show how one can calculate the performance of cooling system components. By becoming familiar with the analyses presented in the examples, one can gain a feel for representative values of the various thermal and mechanical parameters that characterize cooling systems.

Refrigeration is the process of removing heat from an enclosed space, or from a substance, and moving it to a place where it is unobjectionable. The primary purpose of refrigeration is lowering the temperature of the enclosed space or substance and then maintaining that lower temperature. This book reviews research on refrigeration including an overview of up-to-date developments and technology in the field of magnetic refrigeration at room temperature (RTMR); an alternative approach based on artificial neural networks (ANNs) to determine thermodynamic properties of refrigerants; solar powered sorption refrigeration and air conditioning; the modelling of chilling and freezing processes and others.

This book is designed for a first course in Refrigeration and Air Conditioning. The subject matter has been developed in a logical and coherent manner with neat illustrations and a fairly large number of solved examples and unsolved problems. The text, developed from the author’s teaching experience of many years, is suitable for the senior-level undergraduate and first-year postgraduate students of mechanical engineering, automobile engineering as well as chemical engineering. The text commences with an introduction to the fundamentals of thermo-dynamics and a brief treatment of the various methods of refrigeration. Then follows the detailed discussion and analysis of air refrigeration systems, vapour compression and vapour absorption refrigeration systems with special emphasis on developing sound physical concepts and gaining problem solving skills. Refrigerants are exhaustively dealt with in a separate chapter. The remainder chapters of the book deal with psychrometry and various processes required for the analysis of air conditioning systems. Technical descriptions of compressors, evaporators, condensers, expansion devices and ducts are provided along with design practices for cooling and heating load calculations. The basic principles of cryogenic systems and applications of cryogenic gases and air liquefaction systems have also been dealt with. The Second Edition incorporates: (a) New sections on vortex tube, solar refrigeration and magnetic refrigeration, in Chapter 2. (b) Additional solved examples on vapour compression refrigeration system using the R134a refrigerant, in Chapter 4. (c) New sections on duct arrangement systems and air distribution systems, in Chapter 15. (d) A new Chapter 17 on Food Preservation.
