442 Commercial Refrigeration II (18 hours / 60 days)                                                    Advanced

Written by Dick Wirz

 This course is a continuation of 441 HVACR Commercial Refrigeration I.  Again, we will compare things you’re already familiar with like basic AC systems to those of commercial refrigeration systems.  We will examine compressor motor controls, retrofitting, recovery, evacuation, and charging; various supermarket refrigeration systems, walk-in refrigerators and freezers, and commercial ice machines so you can identify the components, their functions, and the refrigerants belonging with each application.  After you’ve got a good understanding of the equipment, we’ll explore appropriate temperatures for products kept in that equipment.  And finally, you will understand when to apply TROT in the absence of a manufacturer’s recommendation.  This course is divided into these learning modules: 

  • Compressor Motor Controls
  • Retrofitting, Recovery, Evacuation, and Charging
  • Supermarket Refrigeration
  • Walk-in Refrigerators and Freezers
  • Ice Machines
  • Product Temperatures for Preservation and Health – Refrigeration Business Tips
