A Textbook of Refrigeration and Air Conditioning is a reference book on theuses of refrigeration and air-conditioning for students of engineering. The subject of this book is one of great significance as public focus shifts to food processing and preservation technologies. The book highlights the need for experts well-read in the essentials of this technology. The book elaborates on the basics of this subject by including discussions on topics like multiple evaporator and compressor systems, simple and compound vapour compression refrigeration systems, air refrigeration cycles and systems, psychrometry, vapour absorption refrigeration and compressor systems, comfort conditions, psychrometry, refrigerants and compressors, cooling load estimation, steam jet refrigeration system, evaporators, condensers, expansion devices and food preservation including cryogenics, fans and ducts. This book also features real-world uses of refrigeration and air conditioning, so helping to support the academic information now assembled. The new edition features colour pictures and refrigeration tables with charts, which help improve the value of the content and support the students to bridge the gap among philosophy and preparation.
