CAIRO BOOKS's Description
Ideal for students and beginning technicians, Electricity for Refrigeration,
Heating and Air Conditioning, 7E 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. Chapter 9 includes new information on motor frames and
electronically commutated motors, ECM. 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.
