HV005H: Motors and Electric Control Systems

The student will learn the function of various electrical components and functions such as transformers, single-phase and three-phase power distribution, capacitors, the theory and operation of induction motors and the instruments and techniques used in testing AC circuits and components. This class also reviews electrical safety and explains the theory of solid-state electronics, as well as the operation, use and testing of electronic components used in HVACR equipment. This class will familiarize the students with the operation, testing and adjustment of conventional and electronic thermostats, as well as the operation of common electrical, electronic, and pneumatic circuits used to control HVACR systems. This class also explains how to analyze circuit diagrams for electronic and microprocessor-based controls used in comfort heating and cooling equipment and how to troubleshoot systems that use these controls. The students will be exposed to the tools, instruments and techniques used in troubleshooting gas heating appliances, including how to isolate and correct faults. Also covered are the techniques and equipment used in troubleshooting cooling equipment, focusing on analyzing system temperatures and pressures to isolate faults.
