Preface

text DeVeLoPMent
This text was developed to provide the technical information necessary for a technician to
be able to perform satisfactorily on the job. It is written at a level that most students can
easily understand. Practical application of the technology is emphasized. Terms commonly
used by technicians and mechanics have been used throughout to make the text easy to read
and to present the material in a practical way. Many of these key terms are also defined in
the glossary. This text is updated regularly in response to market needs and emerging trends.
Refrigeration and air-conditioning instructors have reviewed each unit. A technical review
takes place before a revision is started and also during the revision process.
Illustrations and photos are used extensively throughout the text. Full-color treatment of
most photos and illustrations helps amplify the concepts presented.
No prerequisites are required for this text. It is designed to be used by beginning students,
as well as by those with training and experience.

orGAnizAtion
Considerable thought and study have been devoted to the organization of this text. Difficult
decisions had to be made to provide text in a format that would meet the needs of varied
institutions. Instructors from different areas of the country and from various institutions
were asked for their ideas regarding the organization of the instructional content.
The text is organized so that after completing the first four sections, students may concentrate on courses in refrigeration or air conditioning (heating and/or cooling). If the objective
is to complete a whole program, the instruction may proceed until the sequence scheduled by
the school's curriculum is completed.
