What will I learn?
You will learn how commercial refrigeration systems work from the ground up, starting with thermodynamic principles and refrigeration cycles. The course covers electrical schematics, control circuits, and motor systems so you can diagnose faults accurately. You will study every major component, from compressors and condensers to expansion valves and evaporators. Refrigerant recovery, charging, leak detection, and SA regulatory requirements are covered in full. Installation procedures, system commissioning, and preventive maintenance programmes are included to prepare you for real job-site demands. Advanced topics such as CO2 transcritical systems, multiplex rack configurations, and IoT-connected monitoring round out your training.
