HVC 250 - HVAC Refrigeration I

Credit(s): 3

Prerequisite(s): HVC 140 .
This course introduces to the mechanical compression refrigeration cycle and the necessary components. Students will be introduced to the common terms and definitions of the cycle as well as what, when, and where to measure temperatures and pressures for diagnostics. An in-depth discussion of the four major components (Compressor, Condenser, Metering Device, Evaporator) will conclude with all of them working together in a hypothetical system moving heat energy.  (Fall Semester)

Course Learning Outcomes: Upon completion of the course, students will be able to
  • Identify and explain the reference points of boiling point, freezing point, critical temperature, and absolute zero.
  • Define and apply HVAC applications to specific heat, sensible heat, latent heat of fusion, and latent heat of vaporization.
  • Explain the concepts of a refrigerant cycle diagram and label each of the basic components.
  • Calculate problems using temperature/enthalpy, and pressure/enthalpy diagrams.
  • Identify the major components of vapor compression refrigeration.
