Troubleshooting And Servicing Heat Pumps

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.

This program is designed to provide students and technicians with a comprehensive overview of the heat pump system, its operation, and principles. Heat Pumps; Operation, Installation, and Service is designed to provide the reader with a comprehensive overview of heat pump systems. The manual covers basic principles of operation, system components, air flow, defrost methods, balance point, auxiliary electric heat, electrical control wiring, refrigerant piping, installation, refrigerant charging, troubleshooting, dual fuel systems, and an introduction to geothermal systems. The intent of the book is to offer students and 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 servicing 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. These systems pose new demands for installers and service technicians. New heat pump systems with single, dual, and variable capacity are being sold which requires trained technicians with the ability to install, service, and maintain this equipment.

This fully illustrated handbook takes an in-depth look at recent innovations in heat pump technology and applications, providing the reader with the information needed to understand the principles used in all types of air-source and water-source heat pumps, including multi-unit systems. Readily understandable guidelines will assist the engineer, specifier or technician in determining the appropriate system for a specific application, as well as in installing the system properly. System maintenance, troubleshooting and repairing are thoroughly covered. Other topics include fundamentals of refrigeration applicable to heat pumps, and heat pump components and circuitry.
