Electricity for Refrigeration, Heating and Air Conditioning 8th Edition will provide you with the basic electrical principles necessary to understand today's modern control systems!
The practical approach taken in this book allows you to focus exclusively on the electronics information you will use in the field, without bogging you down in unnecessary theory. Electricity for Refrigeration, Heating and Air Conditioning 8th Edition places an emphasis on developing systematic diagnosis and troubleshooting methods and procedures that will enable you to become a highly-skilled, professional HVAC-R service technician. A comprehensive glossary is also included to assist those who are new to the field in understanding and using industry terms.
New to this edition:
From the Preface
- Chapter 13 revisions to include additional electronic controls.
- Addition of chapter 16 (Residential Air-Conditioning Controls Systems) which includes residential air conditioning control systems, furnace control heating systems, and heat pump control systems, along with a sequence of operation of each. An overview of equipment configuration is also included, as is a short section on customer relations.
- Includes a basic overview of commercial and industrial control systems in chapter 17, including the basic circuitry of light commercial equipment, control methods for commercial and industrial conditioned air systems, an explanation of the control loop as it relates to commercial and industrial systems, as well as a brief explanation of pneumatic and direct digital control systems.
- Contains "green" awareness paragraphs placed in appropriate positions in the text.
Electricity for Refrigeration, Heating and Air Conditioning was initially written because there was no text that adequately covered the electrical principles and practices required of an installation or service technician in the refrigeration, heating and air-conditioning industry. Much material has been added to this text since the first edition because of the advancements that have been made in the industry such as electronic control devices, digital thermostats, digital electrical meters, intermittent ignition for furnaces, electronically commutated motors, direct digital control systems, and many more. This text is written with a blend of theory and practice suitable for the vocational/technical student or the industry practitioner who wishes to upgrade his or her knowledge and skills. The purpose of this text is to assemble concepts and procedures that will enable the reader to work successfully in the industry.
It is difficult to organize an electrical text to be used in refrigeration, heating and air-conditioning programs because of the many different types of programs and the variety of the delivery of information. The information covered in this text is organized from the very basics to the circuitry and troubleshooting of the control systems in the industry. The organization is industry driven because of the correlation of the industry standards and the many new developments that continue to be made. Electrical devices are covered in detail in a systematic order with the troubleshooting of the components following an explanation of how they work. Troubleshooting control systems should be the objective of most students and industry personnel using this text and is covered in detail.
There are new features as well as existing features of this text that are advantages to students and instructors alike. Each chapter begins with objectives that should be mastered as the student progresses through each chapter. Key terms are emphasized at the beginning of each chapter in order of the student to know what information is ahead, and the key terms are highlighted in color in the body of the text. Each chapter is concluded with a summary that allows the student to review information that has been covered in the chapter. Many chapters use service calls to reinforce service procedures that are commonly used in the industry along with some procedures that the student has the opportunity to solve. Important elements of the text are highlighted in color in this edition, including circuits that are being discussed and important concepts and safety cautions. In the back of the text, there is a reference chart of electrical symbols including switches, thermostats, contractors, and relays, and other electric devices.
The art in this edition will be in full color with many of the diagrams showing modes of operations highlighted in different colors. Color photographs will give the reader a more realistic view of what components and equipment look like. Minor revisions were made in chapters covering electrical safety, basic electricity, and electric circuits. The emphasis in Chapter 4 (Electric Meters) was to revise the art so that more current electrical meters were shown. Additional colors have been added to the schematic diagrams that show the operating sequences of the equipment in different colors. Chapters 7-12 and 14 are greatly improved by utilizing a full color art program. The thermostat section of Chapter 12 covers the latest in digital and programmable thermostats. Troubleshooting chapters basically are the same except for covering procedures for any new components introduced in the text.
