Electronic Controls for Commercial Refrigeration Made Simple

This presentation will start from basic refrigeration fundamentals to modern conventional control and operation of coolers and freezers for commercial refrigeration applications. Next, the presentation will show how the conventional components are no longer effective/efficient in keeping up with today's more demanding requirements for efficiency and accessibility for monitoring and controlling from multiple locations; this also includes access from remote locations using the WEB. This is where the electronic components are introduced and explained how they work in each part of the system and what it takes to maintain these parts compared to their conventional counter-parts. Lastly, the presentation will show how the electronic system can perform "Self-Diagnostics", show system Errors, and can trigger Alarms if needed, to help prevent unnecessary product loss and serious revenue loss as well. The system can call to send an automated message to a service company for service.


  1. Be able to identify the difference between electro/mechanical systems and electronic systems as it pertains to commercial refrigeration.
  2. Describe how an electronic control works compared to the current electro/mechanical control standard.
  3. Be able to investigate the many possibilities of where these electronic type commercial refrigeration control systems can be used effectively.
  4. Analyze the prospect of better climate control and energy savings from using electronic controls in commercial refrigeration.
