HVAC Installation/Operations - HVAC 2
This one-credit course introduces students to different components of refrigeration systems and the
function of each component. Emphasis is placed on physical science concepts involved in the
operation of a refrigeration system.
Students enrolled in this course exhibit a mechanical aptitude as well as the ability to comprehend
both verbal and hands-on instruction. They are able to understand informational reading text and
transfer that information to a drawing to illustrate refrigerant flow throughout the refrigeration
system. Students apply mathematics skills for converting from one scale to another and perform
basic functions used in formulas.
Instruction consists of individual and group classroom instruction and laboratory activities. Students
gain knowledge of the theory of thermodynamics and physical science used in the heating,
ventilation, air-conditioning, cooling, and refrigeration (HVACR) industry. Upon completion of this
course, students draw and label parts of a refrigeration system and explain the operation of each
component. The prerequisite for this course is Introduction to HVACR.
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 for HVACR.
2. Draw a basic refrigeration system, including refrigerant flow, components, and lines.
3. Demonstrate the procedure for installing filter dryers.
Examples: liquid-line filter dryer, suction-line filter dryer
4. Demonstrate the procedure for installing and removing a gauge set.
5. Demonstrate pressure temperature conversion procedures.
6. Determine pressures and temperatures on domestic and commercial refrigeration systems.
7. Demonstrate industry-recognized evacuation procedures for a refrigeration system.
Example: triple evacuation
8. Demonstrate the detection and repair of a refrigerant leak.
9. Demonstrate the process of charging a refrigeration system.
Examples: weigh-in, superheat, subcooling
10. Demonstrate the removal and replacement of a major refrigeration component.
Examples: compressor, metering device, condenser, evaporator
11. Describe the operation of basic components of a refrigeration system.
