INHR 15051 - Leak Detection, Evacuation, Recovery, and Charging

0.83 CR
In this module, the HVAC-R student will learn about leak detection, evacuation, recovery, and the charging service procedure used to troubleshoot, repair and/or maintain the proper operation of mechanical refrigeration systems.

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.
