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
- List the safety hazards associated with handling refrigerant.
- 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.
- Measure and calculate superheat, sub-cooling and compression ratio.
- List the different types of metering devices and explain their operations.
- Calculate Airflow utilizing CFM from velocity and area, total static pressure (TSP), and the fan performance method. (Math Component)
- Explain the refrigerant recovery, evacuation and charging processes on an air conditioning system in cooling mode.
