Training in the basic theory of HVAC electrical circuits and test equipment
This course is intended for the new technican and will teach them the fundamental princples of electric.
Module 1 introduces the student to electrical termonology and basic concepts of electricity. This module is appropriate to students with limited knowledge of electricity and covers Ohm's law, power, series and parallel circuits.
Module 2 introduces basic AC, magnetism, and common electrical components. It begins the coverage of wiring diagrams and their symbols by constructing a very basic circuit diagram.
Module 3 discusses safety practices and introduces additional electrical components. A step-by-step construction of a simplified wiring diagram,covering power, control, and load circuits for a typical packaged air conditioner with electric heat, is developed.
The fourth module covers step-by-step construction of a wiring diagram for a heat pump to teach more advanced diagram-reading skills and control circuit concepts.
Module 5 discusses the construction of various types of meters and explains their applications. Sample problems illustrate the use of meters in electrical troubleshooting and testing.
The sixth module expands on basic AC concepts covered in Modules 1 and 2 as the basis for understanding AC motors and AC power. Also covered are the basic concepts of motors and generators, capacitors, phase shift, and power distribution systems.
Module 7 covers basic theory and operation of common single-phase and three-phase AC induction motors, including motor starting circuits. The module also describes the various types of protective devices used with motors.
Module 8 discusses basic concepts, packaging, and troubleshooting of electronic circuits used in comfort air conditioning. The module covers semiconductors, timing and sensing devices, and the use of microprocessor controls in comfort applications.
Module 9 describes and illustrates techniques for troubleshooting electrical and electronic circuits with a focus on control circuits and motors.
