HVAC Refrigeration Processes - HVAC 3
This is a one-credit course that introduces students to electrical components and controls for the
heating, ventilation, air-conditioning, and refrigeration (HVACR) system. Emphasis is placed on
advanced problem-solving techniques in respect to electrical components and circuitry. Students
enrolled in this course possess good problem-solving skills as well as an ability to follow flow charts
and diagrams. They also exhibit good reading and writing skills as well as basic mathematics skills.
Instruction in this course consists of both individual and group classroom and laboratory activities.
Students learn to systematically troubleshoot electrical problems in the HVACR system. Upon
completion of this course, students demonstrate skills necessary to identify problems and replace
defective electrical components in an HVACR system. Skills learned in this course may also be used
in other trades.
Career and technical student organizations are integral, cocurricular components of each career and
technical education course. These organizations serve as a means to enhance classroom instruction
while helping students develop leadership abilities, expand workplace-readiness skills, and broaden
opportunities for personal and professional growth.
Students will:
1. Demonstrate safety rules, regulations, and procedures when working with electrical circuits
used in HVACR systems.
2. Demonstrate techniques involved with assembly and disassembly of a single-phase motor.
3. Determine resistance of windings in a split-phase motor to identify start-run windings.
4. Determine common start-and-run terminals of a single-phase compressor motor.
5. Demonstrate preventive maintenance procedures for a window air conditioner.
6. Demonstrate the procedure for replacing a double-shaft fan motor.
7. Demonstrate troubleshooting techniques to solve electrical problems encountered in HVACR
electrical systems.
8. Demonstrate procedures used for replacing electrical components in an HCACR system.
9. Interpret schematic wiring diagrams for HVACR systems and system controls.
