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
