Description:
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.
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
