0.83 CR
In this module, the HVAC-R student will learn about the mechanical refrigeration systems normally found in retail establishments. This equipment includes reach-in and walk-in coolers and freezers, ice machines, and other appliances used in stores, restaurants, and hotels. The HVAC-R student will also learn about the refrigeration process and defrost techniques, as well as troubleshooting and maintenance procedures.

Course Learning Outcomes:
  1. Explain the phase change, and how the refrigeration cycle uses the manipulation of latent heat to create the cooling effect.
  2. Explain and demonstrate subcooling and superheat.
  3. Name and understand the function of the main refrigeration components including compressors, condensers, metering devices, evaporators, and control devices.
  4. Identify different types of components such as compressors and controls.
  5. Identify and define different refrigerants, and refrigeration oils, their regulation, and how they impact the atmosphere.
  6. Demonstrate proper refrigerant handling, including evacuation, recharging, and leak checking systems.
  7. Analyze the differences between small-scale systems, through commercial and industrial refrigeration systems, and their related equipment and controls.
