Refrigeration and Airconditioning--------------------------------------------------Written by an outstanding teacher with 30 years of distinguished careerat the Indian Institute of Technology Kharagpur, this work createdby late Dr. R.C. Arora (1945 2005) is intended to lead students toa deeper understanding and a firm grasp of the basic principles ofthis fast-growing and exciting subject area. This text is ideally suitedfor undergraduate education in mechanical engineering programmes andspecialized postgraduate education in thermosciences. The book is designedto typically appeal to those who like a more rigorous presentation.The text begins by reviewing, in a simple and precise manner, the physicalprinciples of three pillars of Refrigeration and Air Conditioning,namely thermodynamics, heat transfer, and fluid mechanics. Followingan overview of the history of refrigeration, subsequent chapters provideexhaustive coverage of the principles, applications and design of severaltypes of refrigeration systems and their associated components suchas compressors, condensers, evaporators, and expansion devices. Refrigerantstoo, are studied elaboratively in an exclusive chapter. The secondpart of the book, beginning with the historical background of air conditioningin Chapter 15, discusses the subject of psychrometrics being at theheart of understanding the design and implementation of air conditioningprocesses and systems, which are subsequently dealt with in Chapters16 to 23. It also explains the design practices followed for coolingand heating load calculations. Each chapter contains several worked-outexamples that clarify the material discussed and illustrate the useof basic principles in engineering applications. Each chapter alsoends with a set of few review questions to serve as revision of thematerial learned.
