This book is a fundamental text on air conditioning systems that combines design principles with real-world applications-explaining all concepts in a clear, practical manner, and focusing on problems and examples typically encountered on the job. Following an overview of the scope of air condi-tioning, the text first reviews the physical principles. Heating and cooling load calculations are then explained in a thorough yet understandable manner. The subject of psychrometrics is presented in considerable detail, since it is at the heart of under-standing air conditioning processes. Construction, selection, design, and performance of air conditioning and refrigeration equipment and systems, and two example projects illustrating design of a heating and cooling system are described in depth. A special chapter is devoted to energy utilization and conservation in design, installation, and operation of air conditioning systems. This book with its thorough and unified presentation is an ideal text for courses in air conditioning and refrigeration-both for degree and diploma-level students in mechanical engineering.
