AC 103B - Introduction to HVAC Mechanical Theory and Application


Credits: 5
Description
This course covers mechanical and electrical safety, basic mechanical math and physics, the refrigeration cycle, system components, enthalpy, and psychrometrics. Labs cover: recovery, evacuation, leak testing, charging, and system measurements.

Student Learning Outcomes
  1. List the safety hazards of associated with handling refrigerant.
  2. Draw the basic mechanical refrigeration cycle with the 4 major components and identify the pressures, temperatures, states of matter in and out of each component.
  3. Measure and calculate superheat, sub-cooling and compression ratio.
  4. List the different types of metering devices and explain their operations.
  5. Calculate Airfllow - CFM from velocity and area. (Math Component)
