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.

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

Compressor Electronics Provide Protection for Adverse Operating Conditions

Many of us are familiar with the metaphor that the compressor is like the heart of an HVAC system.  The “heart” behaves inefficiently with irregular patterns when particular conditions exist within the system that drives the compressor outside of its normal operating parameters.   CoreSense™ technology for Copeland Scroll™ compressors is designed to detect this irregular heart beat much like an EKG monitor does during a visit to the doctor.  Many of the common excursions outside of the operating envelope, like loss of charge, low suction pressure, high discharge pressure, and overcharge, can be detected and ultimately prevented with the proper application of CoreSense technology.  Protecting the compressor and shutting it down before a catastrophic incident saves valuable time and money throughout the service channel.

The following graphic depicts a typical compressor operating envelope for a residential air conditioning application.  The area highlighted in green is where the compressor is designed to operates in the most efficient and optimal way.  Prolonged operation outside this region can lead to significant compressor and system damage.  Four typical operating excursions, the possible causes, and the end of life compressor scenario are denoted around the perimeter of the envelope.  The application of CoreSense technology will proactively detect these excursions and prevent them from causing unwanted damage and costly repairs.

Airplanes, U-Boats & Data Signals: Data Analysis Lessons For Operational Improvement

At this month’s Technology in Action Conference, our Director of ProAct engagements, Jeff Zazzara, and I will be giving a presentation that is at least partially inspired by an article we found on LinkedIn, “The Story of the Way Big Data Shaped World War II” by Michael Moritz, the Chairman of Sequoia Capital. Not only does the article combine two of my favorite topics, history and data, but it also reveals an important data analysis lesson: the importance of data signals.

In the world of data analysis, rows in a spreadsheet are termed “cases” and columns are “signals.” Adding cases to a dataset, such as recording kWh consumption over time, reduces the likelihood of outliers and random variance. However, the most powerful way to find valuable insights from a dataset is to add signals. Adding signals creates context for the data; it can reveal new relationships (correlations) and enable key inferences which drive action.

German WW2, U Boat 534 at Birkenhead Docks, Merseyside, England

In the military context of The Battle of the Atlantic in WWII, the Allies’ dataset had many cases of attempts to sink German U-boats with air-to-sea depth charges, but each case had only one resulting signal: whether the U-boat was sunk, damaged, or unharmed.  Identifying specific actions to improve the success rate of these attacks was very difficult without additional supporting data signals. By adding a variety of signals to their dataset – trigger depth of the depth charge, time elapsed from enemy sighting to engagement, and even color of the aircraft – British Intelligence was able to build context into their data and identify potential tactical improvements. As a result, they painted black airplanes white, changed the trigger depth to 25 feet, and improved the success-rate of attacks on submerged U-boats from one percent to seven percent.

In the HVAC/R context today, I see maintenance managers and energy specialists realizing the value of data signals and taking steps to harness their power. One successful Emerson partner improved their preventative HVAC maintenance scheduling by using the E2 management system to create signals from the number of high space temperature alarms and the percentage of units at a store not meeting temperature differential targets. Armed with new data, they targeted stores and units most likely to fail during the peak summer months.

Emerson’s technologies and solutions, such as CoreSense™ technology and the E2 management system, are creating, and will continue to create, new data signals and new opportunities for operational improvements. The key to creating savings through Smart Data is maximizing the number of data signals available to you and then identifying which ones best drive specific key performance indicators.

Emerson Climate Technologies customers who will attend TAC in a couple weeks will hear Jeff and I further explore the use of data analysis in WWII (ask to hear the bullet-hole story), how maintenance teams are using data signals today, and how Emerson can help you develop a signal-rich improvement plan.

But, I am also interested in hearing from experts outside of the retail market. How are you using signals to find meaning in data and improve your business? What are some of the difficulties you have encountered in your endeavors?
