Emphasizes fundamentals of electricity and electronics with application to heating, ventilating, air conditioning and refrigeration equipment. Provides hands-on instruction in electrical-mechanical applications. Electrical theory is studied to include the laws of Ohm's and Watt's, magnetic principles, inductance, and capacitance in circuits. Identification and construction of series, parallel and combination circuits are explored through lab experiments.
Develops skills in reading wiring diagrams, ladder diagrams, block diagrams, electrical and HVAC/R symbols. Focuses on interpreting electrical/electronics and HVAC/R components in a typical circuit. (Prerequisite: Completion of or concurrent enrollment in 601-107 Electricity and Electronics HVAC)
Focuses on preparing the student to sit for certification tests required by federal and state governments and the Heating, Ventilation, Air Conditioning and Refrigeration (HVAC/R) industry. Students focus on EPA refrigerant-handling 608 exam. Other certification exams are also examined. The student defines goals for this class based on exam needs.
Focuses on the fundamental principles of refrigeration, refrigerants, the refrigeration system and control devices. Develops skills and knowledge in the diagnosis and repair of air conditioning and refrigeration systems.
Develops basic skills in the use of refrigeration test instruments, tools and the application of refrigeration theory and practices to refrigeration systems. Skills applied are brazing techniques, evacuation, dehydration and charging of refrigeration systems. The effect of various metering devices is analyzed. Covers wiring of a refrigeration trainer and ways to recover refrigerant from a system using recovery machines as outlined in EPA Section 608 of the Clean Air Act. (Prerequisite: Completion of or concurrent enrollment in 601-120 Fundamentals of Refrigeration)
Develops skills and knowledge in the diagnosis, repair and installation of air conditioning systems. Focuses on service and installation techniques for residential systems. Simulation software and actual equipment provide troubleshooting experience. (Prerequisites: 601-108 HVAC Schematics; 601-121 Refrigeration Service Techniques; 890-101 College 101. Completion of or concurrent enrollment in 103-159 Computer Literacy – Microsoft Office)
Develops advanced skills and knowledge of installation, maintenance and servicing of residential heating systems. Covers control devices, service tools, human comfort and add-on purchases. Simulation software and actual equipment provides troubleshooting experience. (Prerequisite: 601-108 HVAC Schematics)
Develops advanced skills in the preventative maintenance and repair of commercial heating and air conditioning systems. Focuses on systems, start-up, preventative maintenance, service, troubleshooting and installation. Applications center on light commercial, packaged, split and central systems. (Prerequisite: Completion of or concurrent enrollment in 601-123 Residential Heating Systems)
