air conditioning engineering 5th edition pdf
Air conditioning (of which refrigeration is an inseparable part) has its origins in the
fundamental work on thermodynamics which was done by Boyle, Carnot and others in the
seventeenth and eighteenth centuries, but air conditioning as a science applied to practical
engineering owes much to the ideas and work of Carrier, in the United States of America,
at the beginning of this century. An important stepping stone in the path of progress which
has led to modern methods of air conditioning was the development of the psychrometric
chart, first by Carrier in 1906 and then by Mollier in 1923, and by others since.
The summer climate in North America has provided a stimulus in the evolution of air
conditioning and refrigeration which has put that semi-continent in a leading position
amongst the other countries in the world. Naturally enough, engineering enterprise in this
direction has produced a considerable literature on air conditioning and allied subjects.
The Guide and Data Book published by the American Society of Heating, Refrigeration
and Air Conditioning has, through the years, been a foremost work of reference but, not
least, the Guide to Current Practice of the Institution of Heating and Ventilation Engineers
has become of increasing value, particularly of course in this country. Unfortunately,
although there exists a wealth of technical literature in textbook form which is expressed
in American terminology and is most useful for application to American conditions, there
is an almost total absence of textbooks on air conditioning couched in terms of British
practice. It is hoped that this book will make good the dificiency.
The text has been written with the object of appealing to a dual readership, comprising
both the student studying for the associate membership examinations of the Institution of
Heating and Ventilating Engineers and the practising engineer, with perhaps a 75 per cent
emphasis being laid upon the needs of the former. To this end, the presentation follows the
sequence which has been adopted by the author during the last few years in lecturing to
students at the Polytechnic of the South Bank.
In particular, wherever a new idea or technique is introduced, it is illustrated immediately by means of a worked example, when this is possible. It is intended that the text should cover those parts of the syllabus for the corporate membership examination that are relevant to air conditioning.
Inevitably some aspects of air conditioning have been omitted (the author particularly
regrets the exclusion of a section on economics). Unfortunately, the need to keep the book
within manageable bounds and the desire to avoid a really prohibitive price left no choice
in the matter.
