| This book is divided into four sections: Refrigeration Fundamentals; Electrical Fundamentals; Tools, Equipment, and Meters; and HVAC-R Equipment. Section 1: Refrigeration Fundamentals helps you become familiar with the basic principles of refrigeration. By understanding the laws of heat transfer and how they affect the operation of a refrigeration system, you will be more confident when diagnosing and correcting system problems. Section 2: Electrical Fundamentals helps you understand how alternating current is generated, how it is transported from the generating station to the end user, and how it is distributed throughout a building. Section 3: Tools, Equipment and Meters contains material that will help you use test meters, gauges and other equipment to evaluate the performance of equipment and diagnose malfunctions. These tools, equipment and meters will also help you make repairs once the problem has been diagnosed. Section 4: HVAC-R Equipment describes various types of refrigeration and air conditioning equipment, and covers 20 specific troubleshooting problems. The book's Appendix includes troubleshooting charts and guides for refrigeration, remote condensing units, evaporative coolers, refrigerators, hot surface ignition systems, spark-to-pilot ignition systems, condensing gas furnaces, direct gas-fired industrial air heaters, water-to-air heat pumps, heat pumps, electronic air cleaners, and industrial electronic air cleaners.
Beginning with the essential fundamentals, this book takes a straight-forward approach to repairing and maintaining small refrigeration equipment, commercial equipment and residential HVAC-R systems. It also provides detailed troubleshooting scenarios throughout to promote critical thinking skills. Includes:
- A separate unit on electrical components used in HVAC-R equipment
- Separate units on domestic, commercial and comfort cooling/heating equipment
- Diagnostic charts for ready reference
- Numerous troubleshooting problems to give readers a hands-on opportunity to apply knowledge
- Tips and tricks from experienced professionals
- Perfect complement to any HVAC-R book.
