This 78-page book provides a comprehensive overview of the heat pump system, it¿s operations and principles. The heat pumps covered in this book are basic systems. The intent of the book is to offer technicians information to build upon to enhance their knowledge of the air conditioning and heating field, specifically, heat pumps. Before installing or servicing a heat pump system, the technician must have proper training and knowledge of air conditioning/refrigeration theory, principles and operation. New highly efficient equipment 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 unique field guide discusses in detail the various aspects of heat pump selection, installation, and service. This book covers basic heat pump operation, including: a review of the refrigeration cycle, heat pump configurations, four-way valves, electrical schematics, defrost systems, controls and accessories, the scroll compressor, and service and troubleshooting.
The BTU Buddy Notebook is a collection of more than 50 unique service call scenarios conducted by an HVAC technician which describe real-life service scenarios related to troubleshooting. Many high quality images help to illustrate troubleshooting techniques and the equipment being serviced.
