Preface :
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.
New In This Edition :
The art in this edition will be in full color with many of the diagrams showing modes of operation 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.
