HVA 102 - Air Conditioning Theory
Covers the physical principles of air conditioning, psychometrics and air movement. Components found in today's air conditioning systems will be examined. Students will learn how to charge and evacuate systems. Other topics included are: pressure, regulating and bypass controls, diffusers, piping procedures, traps and high velocity systems. Two class hours, two laboratory hours.
Prerequisite: HVA 101.
Course Learning Outcomes
1. Describe the basic refrigeration components associated with air conditioning systems.
2. Install air conditioning systems to manufacturer Original Equipment Manufacturer (OEM) standards.
3. Explain the basic control and power circuit of air conditioning systems.
4. Evaluate operating system super-heat and sub-cooling to judge appropriate system operating conditions.
5. State common rules of thumb in air conditioning applications for good air flow in A/C systems.
6. Identify common supply system ducting configurations and practices.
7. Measure and calculate system airflow.
8. Utilize appropriately basic psychrometric terms and definitions.
9. Measure psychrometric conditions to plot points on psychrometric charts.
10. Interpret the psychrometric charts to evaluate appropriate air conditions for human comfort.
11. Apply psychometric formulas to the measurement of psychrometric conditions.
12. Perform a Manual J heating and cooling load calculation for a small residential structure to size a forced air heating and cooling system properly.
