Tropical Refrigeration And Air Conditioning

Tropical Refrigeration and Air-Conditioning covers the syllabuses of theoretical and practical Craft level examinations in refrigeration and air-conditioning. It is designed for trainee installation and service engineers and will be of permanent practical value to them in their work. Key features of the book are: over 200 photographs and clearly labelled illustrations glossary of important terms sample examination papers for evaluation and revision a 'trouble-shooting' chart for identifying and remedying defects in equipment

Principles of Tropical Air Conditioning is written with the humid tropics in mind. It is intended to meet the syllabus of the Higher National Diploma (HND) or equivalent professional examinations in Building Services Engineering. It is also designed to cover the air conditioning course content of the new Bachelor of Engineering (B. Eng) degree approved by the National Universities Commission. It is specifically focused in providing design data for tropical air conditioning system design and provides illustrative examples that can give young practitioners enough information to evaluate air conditioning and refrigeration cooling loads and equipment selection with minimum supervision. In addition, Principles of Tropical Air Conditioning serves as quick reference source containing useful design data and parameters often required by the practicing engineer.

This textbook provides a concise, systematic treatment of essential theories and practical aspects of refrigeration and air-conditioning systems. It is designed for students pursuing courses in mechanical engineering both at diploma and degree level with a view to equipping them with a fundamental background necessary to understand the latest methodologies used for the design of refrigeration and air-conditioning systems. After reviewing the physical principles, the text focuses on the refrigeration cycles commonly used in air-conditioning applications in tropical climates. The subject of psychrometry for analysing the various thermodynamic processes in air conditioning is particularly dealt with in considerable detail. The practical design problems require comprehensive use of tables and charts prepared by the American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE). This text incorporates such tables and charts so that the students are exposed to solving real-life design problems with the help of ASHRAE Tables. Finally, the book highlights the features, characteristics and selection criteria of hardware including the control equipment. It also provides the readers with the big picture in respect of the latest developments such as thermal storage air conditioning, desiccant cooling, chilled ceiling cooling, Indoor Air Quality (IAQ) and thermal comfort. Besides the students, the book would be immensely useful to practising engineers as a ready reference.

Solar cooling is most effective where it is most needed - in the tropics. Most developing countries lie in the hotter climatic regions, where cooling facilities are essential to promote the well-being, productivity and comfort of the population. Paradoxically, solar air-conditioning can contribute significantly to the alleviation of the problem. This book includes fully detailed treatment of the theory and applications of the techniques involved: vapour absorption systems, solar absorption systems, solar absorption cooling, radiative cooling and desiccant cooling. Particular applications stressed include the use of passive cooling in buildings and the provision of efficient refrigeration facilities, the latter being essential for the storage of vaccines in health-care programmes for the eradication of infectious diseases throughout the developing world.

The use of refrigeration, either directly or as part of an air-conditioning system, is essential to almost every branch of industry. There is a need for practitioners to familiarise themselves with the general principles and methods of refrigeration and air conditioning, and the types of plant and operation currently in use. This book provides a comprehensive introduction to the principles and practice of refrigeration and air-conditioning for the uninitiated student and a general overview of the industry for the practitioner. The fundamentals of the subject are introduced without involving the reader too deeply in theory and the content is presented in a logical order. This fully revised and updated third edition has a new chapter on Refrigerants that deals with the many changes in this area over the last 10 years, including the phase out of CFC and HCFC refrigerants in line with Ozone depletion and Global Warming. New, replacement refrigerants are described, together with Codes of Practice introduced for maintenance and servicing of refrigeration plants. The increased use of Ammonia and Propane are included, with the relevant Health and Safety aspects, and the move towards Absorption refrigeration equipment as more environmentally friendly. This new edition of Refrigeration and Air Conditioning is a valuable reference source for practising engineers and essential reading for students.

The Revised Edition Of A Widely Used Book Contains Several New Topics To Make The Coverage More Comprehensive And Contemporary. * Highlights The Ozone Hole Problem And Related Steps To Modify The Refrigeration Systems. * The Discussion Of Vapour Compression/Absorption Systems Totally Recast With A Special Emphasis On Eco-Refrigerants. * Application Oriented Approach Followed Throughout The Book And Energy Efficiencyemphasised. * Several Real Life Problems Included To Illustrate The Practical Viability Of The Systems Discussed. * Additional Examples, Diagrams And Problems Included In Each Chapter For An Easier Grasp Of The Subject.With All These Features, This Book Would Serve As A Comprehensive Text For Undergraduate Mechanical Engineering Students. Postgraduate Students And Practising Engineers Would Also Find It Very Useful.

For thousands of years, humans coped with heat by harvesting and storing natural ice and devising natural cooling systems that utilized ventilation and evaporation. By the mid 1800s, people began developing huge refrigeration machines to manufacture ice. By the early 1900s, engineers developed electric domestic refrigerators, which by 1927 were affordable convenient household appliances. By then, an increasingly sophisticated public demanded more modern-looking appliances than engineers could produce, and a new breed of designers entered the manufacturing world to provide them. During the Depression, modern designs not only increased sales but resulted in the kitchen appliances we now use. Today refrigeration preserves perishable food for worldwide distribution, makes tropical climates habitable for millions, saves lives with medical applications and enables space flight.
