Bring must-know electrical concepts and HVAC service procedures to life! Designed to coordinate with our Electricity for Refrigeration, Heating, and Air Conditioning book by Russell Smith, this new series of twelve videos is an excellent way to introduce essential electrical topics, from basic concepts of electricity through motors and controls. The first set of four tapes focuses on the basics, including: safety attire and equipment; relationships between current, resistance, and electromotive force; use of the ammeter, voltmeter and ohmmeter; plus different types of wiring diagrams and how to read simple schematics. The second set of four tapes takes a look at fundamental principles of alternating current and power distribution in action, familiarizes viewers with five types of motors, and explains the use of relays in HVAC systems. The final set of four tapes shows the actual operation of contractors and relays and explains how to troubleshoot overloads. The inner workings of popular warm-air and hydronic heating applications, plus residential and commercial AC systems, are also revealed to viewers.
