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.

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.
