CoreSense™ Compressor Diagnostics Save Merchandise and Reputations

Imagine: you close your market at the end of the day, and the next morning you return to find your merchandise spoiled because your refrigeration system failed overnight. Though it doesn’t happen often, it takes just one failure to cause catastrophic losses for large and small businesses alike.

For one small-town meat market, this nightmare nearly happened due to a faulty defrost timer on the walk-in cooler. On an ordinary system, a series of events would occur, eventually ending with spoiled meat and possibly ruined equipment. But because the market’s cooler had a Copeland Scroll™ K5 compressor with CoreSense technology, quick action from staff saved both the meat and the refrigeration equipment.

While the timer is not part of the compressor itself, the CoreSense diagnostics technology was still able to save the cooler from failing. It sent an alert to the facility manager, who brought in a qualified contractor to identify the issue with the timer, repair it and reset the compressor. More than $10,000 in food was saved, and the compressor and cooler weren’t damaged. And since store managers became aware of the issue as it occurred, they were able to closely monitor product integrity and ensure they maintained the quality their customers expect.

Ideally, like in the meat market situation, personnel would respond quickly to the notification and address the cause of the failure. If no one responds, however, CoreSense directs the refrigeration system to reset itself for up to four hours. At the end of this four-hour time period, it shuts down the compressor and waits for a manual reset. Although the food would begin to spoil at this point of the scenario, the refrigeration equipment would be saved.

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 www.emersonclimate.com/makingsensewebinars.  Stay tuned for the next set of our Making Sense Webinar Series.

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.

Making Sense of Low Condensing Refrigeration — Webinar Wrap-Up

We recently hosted the second installment of our educational Making Sense webinar series. Judging from the large number of attendees (146 during the live event), the subject of low condensing refrigeration is one that is top of mind for many professionals in our industry today.

Overall, we’ve been extremely pleased with the level of participation we’ve seen since launching the webinar series earlier this summer, and are excited to bring other relevant industry topics to the forefront. So far, more than 250 attendees have participated in our first two webinars, and there are more than 120 who have viewed the archives online.

If you’re new to our Making Sense webinars series, our objective is to help refrigeration professionals stay informed of the latest trends that are shaping the industry. In our first webinar, we helped you make sense of the promising role of new refrigerants through our discussion of mid-point vs. dew-point. Most recently, we explored innovations in energy-reduction technologies by taking a closer look at the potential of low condensing refrigeration.

Our next webinar will show retailers how to improve operational visibility using compressor electronics data. Join us on September 17 at 2 p.m. EDT for an introduction of the fundamentals of Emerson’s CoreSense™ technology and a discussion of how to leverage this valuable data. This free webinar will demonstrate how simple data analytics can uncover opportunities to enhance the performance of your HVAC and refrigeration systems.

We know that many of you have registered for one of our webinars, but for whatever reason have been unable to participate in a live event. That’s why we’ve also made our webinars available online via our website, so you can view them on-demand at your convenience.
