Electricity and Controls for HVAC

This edition has been written with the assumption that the student has no prior knowledge of electricity or control systems relative to HVAC-R. Basic electrical theory is presented in a practical, straight forward manner. The text begins with basic electrical theory and progresses to alternating current, series and parallel circuits, and resistive, inductive, and capacitive circuits. Individual devices and components common to the air conditioning, refrigeration, and heating field use are presented in a practical manner. Furthermore, it includes a new section on residential and commercial icemakers and their control systems.
