Electricity and Controls for HVAC/R is written with the assumption that the student has no prior knowledge of electricity or control systems. Basic electrical theory is presented in a practical, straightforward manner. Mathematical explanations are used only when necessary to explain certain concepts of electricity. Each unit starts with the objectives of the unit and ends with a summary of important facts.
Electricity and Controls for HVAC/R, sixth edition, includes information on isolation transformers, autotransformers, and current transformers. The three major types of three-phase motors-squirrel cage induction, wound rotor, and synchronous-are also covered.
