Get the information you need to work effectively with Electricity and Controls for HVAC-R
Now in its fifth 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. 560 pp.
Features:
- Comprehensive coverage of electric motors includes three-phase motors,
squirrel cage induction motors, wound rotor motors, synchronous motors, and
more
- Circuits commonly encountered in the field are explained in a practical,
non-mathematical manner
- New units on brushless DC motors, as well as light-emitting diodes (LEDs)
and photodiodes introduce students to the latest technologies in the field
- Units on programmable logic controllers (PLCs) and programming PLCs are
thoroughly updated to remain current with industry practices
- Requirements for unit installation have been updated to comply with 2005
NEC® standards
