Preface by the puplisher: The science and practice of creating controlled thermal conditions, collectively called refrigeration and air conditioning, is an exciting and fascinating subject that has wide-ranging applications in food preservation, chemical and process industries, manufacturing processes, cold treatment of metals, drug manufacture, ice manufacture and above all in areas of industrial air conditioning and comfort air conditioning. The subject of refrigeration and air conditioning dates back to centuries when refrigeration was achieved by natural means such as the use of ice or evaporative cooling. Refrigeration, as it is known these days, is produced by artificial means. Based on the working principle, the present-day refrigeration systems can be classified into (i) mechanical vapour compression refrigeration systems, (ii) absorption refrigeration systems, (iii) gas cycle refrigeration systems, (iv) steam jet refrigeration systems, (v) thermoelectric and magnetic refrigeration systems, and (vi) vortex tube refrigeration systems.
Most of the present-day air conditioning systems use either a vapour compression refrigeration system or a vapour absorption refrigeration system. This textbook on refrigeration and air conditioning is an outcome of 30 years’ teaching experience of late Professor (Dr.) Ramesh Chandra Arora at the Indian Institute of Technology Kharagpur. It is intended to lead students to a deeper understanding and a firm grasp of the basic principles of this fast-growing subject area. The text is ideally suited for undergraduate education in mechanical engineering programmes and specialized postgraduate education in thermosciences. The book is designed to typically appeal to those who like a more rigorous presentation.
The presentation of the subject is divided into two areas, i.e. refrigeration topics in Chapters 1 to 14 and air conditioning topics in Chapters 15 to 23. Chapter 2, however, may be treated as common between these areas as it comprehensively reviews the basic principles of thermodynamics, heat transfer and fluid mechanics which constitute the three pillars of refrigeration and air conditioning.
After recapitulation of the basic foundations of refrigeration, the follow-on chapters are devoted to exhaustive coverage of principles, applications and design of several types of refrigeration systems and their associated components such as compressors, condensers, evaporators, and expansion devices. Refrigerants too, are studied elaborately in an exclusive chapter. The study of air conditioning begins with the subject of psychrometrics being at the heart of understanding the design and implementation of air conditioning processes. The design practices followed for cooling and heating load calculations and methods of duct designing, are discussed elaborately in separate chapters.
The publisher sincerely hopes that this presentation based on the author’s extensive lifetime experience of teaching and industrial consultancy, will contribute to the knowledge of the students. The presence of late Professor Ramesh Chandra Arora will be sadly missed but constantly felt as a mentor in the form of this book. Let us all hope that he would approve of what has been done.

This textbook offers a comprehensive and wide-ranging introduction to theoretical principles and practical aspects of refrigeration and air conditioning systems. Written by an outstanding teacher with 30 years of distinguished career at the Indian Institute of Technology Kharagpur, this work created by late Dr. R.C. Arora (1945-2005) is intended to lead students to a deeper understanding and a firm grasp of the basic principles of this fast-growing and exciting subject area. This text is ideally suited for undergraduate education in mechanical engineering programmes and specialized postgraduate education in thermosciences. The book is designed to typically appeal to those who like a more rigorous presentation.
The text begins by reviewing, in a simple and precise manner, the physical principles of three pillars of Refrigeration and Air Conditioning, namely thermodynamics, heat transfer, and fluid mechanics. Following an overview of the history of refrigeration, subsequent chapters provide exhaustive coverage of the principles, applications and design of several types of refrigeration systems and their associated components such as compressors, condensers, evaporators, and expansion devices. Refrigerants too, are studied elaboratively in an exclusive chapter.
The second part of the book, beginning with the historical background of air conditioning in Chapter 15, discusses the subject of psychrometrics being at the heart of understanding the design and implementation of air conditioning processes and systems, which are subsequently dealt with in Chapters 16 to 23. It also explains the design practices followed for cooling and heating load, calculations.
Each chapter contains several worked-out examples that clarify the material discussed and illustrate the use of basic principles in engineering applications. Each chapter also ends with a set of few review questions to serve as revision of the material learned.
THE AUTHOR Late Dr. RAMESH CHANDRA ARORA, served as Professor of Mechanical Engineering at Indian Institute of Technology Kharagpur from 1987 to 2005. He joined IIT Kharagpur in 1975 as a lecturer after obtaining his Ph.D. degree in the same year from Case Western Reserve University, Cleveland, Ohio, USA. Professor Arora was regarded as a highly competent subject matter expert in academia and industry alike. His research areas included fluid mechanics, heat transfer, refrigeration and air conditioning, and alternative refrigerants and thermodynamic cycles. During his illustrious career, Professor Arora was the recipient of several outstanding teacher awards, national scholarships, merit awards, and graduate fellowship. He is credited with 91 research publications, 8 technical reports, 19 industrial projects and 3 pending patents.
