Heat Pumps: Operation, Installation and Service covers: heat pump basics, principles of operation, system components, air flow, defrost methods, balance point, electric heat, electrical control wiring, refrigerant piping, installation, refrigerant charging, troubleshooting, dual fuel systems, geothermal systems. This book is designed to provide the reader with a comprehensive overview of the heat pump system, its operations and principles. It should be noted that the heat pumps covered in this book are basic systems. The intent of the book is to offer technicians information to build upon, in order to enhance their knowledge of the air conditioning and heating field, and more specifically, heat pumps. Before installing or service a heat pump system, the technician must have proper training and knowledge of air conditioning/refrigeration theory, principles and operation. With today's energy demands and costs soaring there is a tremendous need for highly efficient equipment, and trained technicians that can install, service and maintain this equipment. New heat pump systems using HFC refrigerant (R-410A) are being sold and installed. These systems pose new demands for installers and service technicians. A heat pump's efficiency can be greatly diminished, regardless of the type of refrigerant, if it is not properly installed, serviced and maintained. This book covers problems and provides solutions to refrigerant charging, indoor airflow calculation, and methods of preventing unnecessary heat pump malfunctions.

Residential energy studies show that: 68% of residential systems are improperly charged, 70% have improper air flow and 91% have not had a combustion efficiency check performed. The System Performance training manual aids technicians in understanding the proper techniques and procedures used to verify and optimize performance of HVAC systems. The manual is broken into four parts covering: airflow, critical charging procedures, psychrometrics, and combustion efficiency. Persons who have finished reading this book can demonstrate their retained knowledge to: reduce warranty cost, reduce call backs and maximize the energy efficiency of heating and cooling equipment, by taking the System Performance Certification exam.

With the majority of HVACR service calls being electrical in nature, it is important for technicians to have a solid understanding of electrical fundamentals allowing them to develop a systematic and methodical procedure for troubleshooting. The Electrical Theory and Application for HVACR manual provides students and practicing technicians with the information and knowledge necessary to accurately diagnose and solve electrical system faults. This manual is full of color illustrations and includes student worksheets. The spiral binding will allow students to tear out worksheets for grading by the instructor. Main topics include: safety and hazard awareness, electrical fundamentals, circuits and components, motors, wiring diagrams, automated control systems, and troubleshooting. This manual replaces Troubleshooting and Servicing HVACR Electrical Systems.
