EBOOK - Air Conditioning and Refrigeration (Rex Miller & Mark R. Miller)

An introduction to the basic principles and practices of the air-conditioning and refrigeration industry is more than just a review of the facts and figures. It requires a complete look at the industry. This text presents the basics of all types of efrigeration. It explains the equipment that makes it possible for us to live comfortably in air-conditioned spaces and enjoy a wide variety of foods.
Up-to-date methods of equipment maintenance are stressed. The latest tools are shown. The applications of the newer types of units are emphasized. The field of air-conditioning technology is still growing and will continue to grow far into the future. New technicians will need to be aware of the fact that change is inevitable. They will have to continue to keep up with the latest developments as long as they stay in the field.

This textbook has been prepared to aid in instructional programs in high schools, technical schools, trade schools, and community colleges. Adult evening classes and apprenticeship programs may also find it useful. This book provides a thorough knowledge of the basics and a sound foundation for anyone entering the air-conditioning and refrigeration field.
The authors would like to give a special thanks toMr. Burt Wallace who is an instructor in the air conditioning and refrigeration program in Tyler Junior College and Mr. Andy Bugg an AC Applications Engineer for one of the largest air conditioning manufacturers for their most valuable contributions to the book. Both live in Tyler, Texas.
