Refrigeration Technology Diploma

This is a comprehensive training program in Refrigeration Equipment Repair and Maintenance. It covers the basic principles of low, medium, and high temperature refrigeration systems. It emphasizes the differences that refrigeration and comfort cooling systems have. It covers major system components, troubleshooting procedures, and types of refrigerants. It covers the operation and maintenance of ice machines, walk-in freezers, refrigerators, and other types of commercial refrigerator “reach-ins”.

Program Description

  • Ref 100 Intro to Refrigeration (12 Hrs)                                                                                                This course includes the basic refrigeration cycle, application of low, medium, and high-temperature systems, and the typical equipment associated with those systems and basic wiring of controls, such as thermostatic expansion valves, capillary tubes, and defrost clocks and defrost systems.
  • Ref 101 Low-Temperature Refrigeration (12 Hrs)                                                                                 This course introduces specific pump-down controls. Students will complete piping and wiring a real walk-in freezer, pressurizing, leak checking, vacuuming, as well as refrigerant charging.
  • Ref 102 Walk-In Freezers (12 Hrs)                                                                                                         This is a continuation of Ref 101 and includes adjusting TXV valves for superheat, calculating sub-cooling, troubleshooting flow controls, and testing compressor efficiency.
  • Ref 103 Commercial Refrigeration (12 Hrs)                                                                                         This course includes an introduction to “reach-ins”.  Students will work on a variety of reach-in refrigeration units.  Students may also finish work on the walk-in, removing the charge, disassembling units, and removing wiring.
  • Ref 104 Ice Machines (12 Hrs)                                                                                                               This course covers the different types of ice machines and their components. The also deals with the cleaning of the equipment, different types of controls to ensure the equipment’s proper operation, and troubleshooting and repair of the equipment.  Water-cooled condensers and remote condensers will also be covered.
