Three Making Sense Webinars Down; More To Come

Over the past three months, our team at Emerson Climate Technologies has been working hard to help you MAKE SENSE of recent transitions in the refrigeration industry. This first set of three webinars addressed critical issues associated with the promising role of new refrigerants, advancements in energy reduction technologies, and opportunities to improve operation visibility.

Back in July, Dr. Rajan Rajendran and Autumn Nicholson presented the Mid-Point vs. Dew Point webinar which focused on the basics of refrigerant blends and “glide”. They also covered how refrigerant glide affects system components and the proper maintenance of systems using refrigerants with glide.

Last month, Mike Saunders, Mitch Knapke, and Andre Patenaude discussed the Implementation of Low Condensing Refrigeration. They discussed the beneficial aspects of low condensing as well as challenges associated with its implementation. This webinar finished off with a look into several interesting case studies, like the application of low condensing in the apple storage project.

Kurt Knapke rounded out the finale of our first set with his discussion on Using Compressor Electronics Data. He covered ideas on how to effectively use compressor electronics data to analyze system operations. We learned that simple data analytics can help identify opportunities to enhance your HVACR equipment performance.

If you missed the chance to watch these webinars live, they are available on demand at  Stay tuned for the next set of our Making Sense Webinar Series.

Are You Up for the Challenge?

We have discussed Emerson Climate Technologies’ transition from mechanical pressure switches for system control and protection in refrigeration equipment to electronic controllers onto Copeland™ condensing units with its Electronic Unit Controller in recent blog posts. This advanced device replaces all mechanical pressure controls, simplifying set-up and provides better performance with reduced call-backs.

In an effort to generate awareness, increase comfort, and educate HVACR professionals, Emerson has developed a platform to support the transition called the “One Minute Challenge.” This campaign was designed to help contractors overcome the “black box” syndrome of using new technology and to create awareness that this game-changing piece of technology simplifies commercial refrigeration system operation while increasing system accuracy, protection, and capabilities. The One Minute Challenge is an online simulator that shows users how they can now complete a standard, 25-minute job in 1 minute.

Here’s how it works:

  • The online simulator allows the user to set-up the electronic unit controller as if they were on the actual jobsite. It times how long it takes each user to complete, and it establishes a leader board showing the top 20 contractors and wholesalers. The tool can be used on iPads and other tablets, as well as a computer.

The top five leading wholesalers and contractors include:


  1. John Tillack, Poleward Refrigeration – 7.90 seconds
  2. Bob Smith, Bob’s A/C – 9.54 seconds
  3. John Jones, Jones HVAC – 13.92 seconds
  4. Lee Page, Equipment Service Company – 14.03 seconds
  5. AJ Milbes, Rio Ranch Market – 15.17 seconds

7.90 seconds is the top time to beat in the One Minute Challenge! Do you think you have what it takes to dominate the top? See for yourself just how easy the Electronic Unit Controller is.

Take the one-minute challenge.

The FMI’s Energy & Store Development 2013 Experience

This year’s Energy & Store Development Conference was held at the Hilton Baltimore and was attended by more than 600 food industry professionals. 

Part of this event included concurrent breakout sessions that were divided into three major categories—Energy, Refrigeration and Store Development.   Among the topics discussed were store formats, energy-efficiency, refrigeration system types, refrigerants, the latest trends in building codes, regulations, and store designs and merchandising.

One of my Emerson Climate colleagues and I were privileged to be able to present during these breakouts.  I presented Refrigerants Update and John Wallace, director, Product Management, Retail Solutions, discussed The Evolution of Energy Management Systems.  Both John and I felt the sessions were well received and were very relevant topics to the industry. 

Overall it was a great event with plenty of ideas and fresh information to go around.  It was a good opportunity to see familiar and new faces and meet with the rest of the food retail industry. 

How about you?  Were you there at the meeting?  What did you find useful about the conference?

Exploring the Real-World Value of Compressor Electronics Data

Nothing demonstrates the value of new technologies better than real-world examples. While preparing for our recent Making Sense webinar on improving operational visibility, I was struck by countless customer testimonies that demonstrate where they saved thousands of dollars through the analysis of data available from CoreSense™ technology. I was excited to include a few examples in the webinar that moved the discussion from theoretical concepts to tangible applications.

First, there was the supermarket that responded to a high case temperature alarm and through troubleshooting was able to identify the root cause as a bad contactor. The data identified the problem early and through remote troubleshooting focused the efforts on the failing contactor. Without compressor electronics the issue would have resulted in a compressor failure. Therefore, the customer simply replaced the faulty contactor, avoided compressor failure and saved approximately $6,000.

Next, a contractor for a convenience store with a walk-in cooler received an alarm that a compressor had overheated. On further analysis of the data, they discovered that a low-pressure, cut-off fault had caused a harmful system loop of cooling, overheating, protector tripping and resetting. With CoreSense technology, the contractor was notified of the problem and arrived on-site to finish troubleshooting. By preventing compressor failure, the store saved $6,000 in replacement costs.

And when a compressor stopped running in a butcher’s walk-in cooler because the defrost timer had frozen, CoreSense warned the contractor of the system trip and then sent an alarm four hours later when the control circuit had not reset. The notifications prompted the contractor to fix the issue before $10,000 of the butcher’s product had spoiled.

These examples demonstrate how a compressor can be effectively used as a sensor. Facilities managers and contractors can use compressor electronics to not only receive notifications of failures before they happen, but also rely on the built-in diagnostics to initiate shut-down sequences when needed. They’re also able to perform proactive maintenance and enhance overall performance reliability. On an enterprise level, compressor data can be used to monitor store-level data to identify top issues, evaluate best- and worst-performing stores, and prioritize equipment and maintenance efforts.

If you were unable to attend the webinar and would like to learn more about compressor electronics data, you may view our archived webinars on our website. And, keep an eye out for our next webinar where we’re Making Sense of the latest trends that are shaping the refrigeration industry at
