Excerpts

Heat Pump Technology, Third Edition,is designed for use by the instructor and students in a classroom environment, or as a source for independent study. The fundamentals are presented first, and then the more complex subjects are covered in detail. Also presented are some recommended service and start-up procedures, troubleshooting charts, and service procedures. Each of the ten chapters is dedicated to a specific area of the heat pump segment of the exciting HVAC industry. Each chapter begins with an introduction to a particular phase of heat pump technology and then presents the more complex aspects of heat pump systems and controls. Most of the chapters conclude with a summary, troubleshooting and repair problem(s), and questions covering the minimum amount of knowledge that the reader should comprehend. English-metric equivalents are included throughout to ease conversions. The text also features representative wiring diagrams to aid the reader in learning how to read heat pump wiring schematics. After studying this text, the reader will have the knowledge and confidence necessary to install and service properly heat pump systems. Special thanks are due to the following reviewers of the third edition: Kate Schiefen, Monroe Community College; R. Wirtz, Columbus State Community College; and Kevin Heath, Richmond Technical Center. Billy C. Langley
