Electricity & Controls for HVAC/R
Description:
|
Sixth
Edition
Authors: Stephen L. Herman,
Bennie Sparkman |
Now in its sixth edition,
ELECTRICITY AND CONTROLS FOR HVAC-R equips readers with the
information needed to work effectively with all types of motors and
control devices found in the heating and air-conditioning industry.
Prior knowledge of electricity is
not required as this book begins with discussion of essential basic
electricity and electrical circuits concepts.
Numerous schematic diagrams and
step-by-step troubleshooting procedures are included to acquaint
readers with all of the different types of circuits commonly
encountered in the HVAC-R field
Stephen L. Herman has been
both an electrician and teacher for over 20 years. He has authored
numerous textbooks on the subjects of electricity and mathematics.
He recently retired from being a
lead instructor for Electrical Technology Curriculum at Lee College
in Baytown, Texas. Mr. Herman received an Excellence in Education
Award by the Haliburton Education Foundation.
Features:
- Many photographs have been replaced and updated along with new
line art.
- Text is updated to the latest technology and reflects the
current National Electrical Code® requirements.
- Text design has been updated to provide ease in navigating
chapter material.
- Unit on atomic structure has been rewritten to reflect the most
accepted theories concerning the structure of atoms.
- The unit devoted to troubleshooting has been expanded to include
an example of a step-by-step procedure for determining the problems
with a central air conditioning system.
- COMPREHENSIVE COVERAGE: Comprehensive coverage of electric
motors includes three-phase motors, squirrel cage induction motors,
wound rotor motors, synchronous motors, and more.
- PRACTICAL EXPLANATIONS: Circuits commonly encountered in the
field are explained in a practical, non-mathematical manner.
- UPDATED UNITS ON LATEST TECHNOLOGIES: New units on brushless DC
motors, as well as light-emitting diodes (LEDs) and photodiodes
introduce students to the latest technologies in the field.
- UPDATED UNITS ON INDUSTRY PRACTICES: Units on programmable logic
controllers (PLCs) and programming PLCs are thoroughly updated to
remain current with industry practices.
- REQUIREMENTS FOR 2008 NEC® STANDARDS: Requirements for unit
installation have been updated to comply with
2008 NEC® standards.
