Electricity for Refrigeration, Heating and Air Conditioning;

Ideal for students and beginning technicians, Electricity for Refrigeration, Heating and Air Conditioning, 6E zeroes in on the basic electrical principles necessary to understand today's modern control systems. This extraordinarily practical approach allows readers to focus exclusively on the electronics information they will use in the field, without bogging them down in unnecessary theory. Newly-updated in direct response to user feedback, this edition now features all-new chapters on electrical safety, reading wiring diagrams, and troubleshooting modern HVAC-R control systems and circuitry. A second color has also been added throughout the book to highlight "must-know" information for readers, such as the circuits being discussed in schematic diagrams, as well as the direction of the current flow within circuits. As in past editions, emphasis is on developing systematic diagnosis and troubleshooting methods and procedures in order to enable readers to become highly-skilled, professional HVAC-R service technicians. A comprehensive glossary is also included to assist those who are new to the field in understanding and using industry terms.
