HVA 101 - Basic Refrigeration Theory
Covers the physical principles of refrigeration and the refrigeration cycle. Students will be introduced to the components of the refrigeration system including compressors, condensers, expansion devices, evaporators, coolers, freezers, and refrigerants. Two class hours, two laboratory hours.
Course Learning Outcomes
1. Identify the four major components and three refrigerant lines within a basic refrigeration system.
2. Describe each major component's specific function within the basic refrigeration cycle.
3. Describe the three general refrigerant applications for refrigerant systems.
4. Describe basic heat transfer theory.
5. Define basic refrigeration cycle terminology.
6. Evaluate system super-heat and sub-cooling to judge appropriate system operating conditions.
7. Diagnose the six most common refrigeration cycle malfunctions, stating the symptoms.
8. Observe common safety practices in the use of various refrigeration equipment service tools (which could include refrigeration manifolds, vacuum pumps, or recovery machines).
9. Identify various common refrigeration system accessory components.
10. Describe various common refrigeration system accessory components.
11. Assemble refrigerant piping projects with traditional field joining techniques, where the piping projects hold a nitrogen pressure test of 100 psi without leaking.
12. Identify federal EPA 608 regulations related to refrigerant chemistry and management.
13. Describe federal EPA 608 regulations related to refrigerant chemistry and management.
