This blog is a summary of the article CoreSense™ Technology Gives Contractors a Sixth Sense from our recent edition of E360 Outlook. Click here to read the article in its entirety.

Compressor failure is a worst-case scenario in commercial refrigeration applications. For supermarket operators, it can mean catastrophic product losses compounded by the expenses of system maintenance, repairs and compressor replacement. For the service technician whose responsibility is to properly diagnose and prevent system faults before they occur, system failures can blemish their reputation.

In a perfect world, retailers would keep a dedicated service technician on-site to continuously monitor refrigeration system performance. But in reality, this scenario is just not feasible. That’s why the advent of built-in compressor electronics — like Emerson’s CoreSense technology — is revolutionizing the commercial refrigeration service paradigm. CoreSense technology provides continuous system monitoring, placing protection and diagnostics at the contractor’s fingertips.

As contractors more frequently encounter these units in the field, the challenge is to not only embrace their obvious benefits, but to exploit their capabilities to their maximum potential.

Communications-enabled connectivity

Designed with advanced communication capabilities, CoreSense technology allows contractors to accurately diagnose and troubleshoot system issues — either at the customer’s site or remotely via mobile device access.

  • PC interface kit — once at the customer’s site, contractors can connect their laptop to the CoreSense module via a USB to RS485 cable. Software then gives the contractor visibility to real-time system data and historical performance to help them quickly analyze and troubleshoot system issues.
  • Remote access — for maximum contractor benefit, CoreSense technology can be paired with a facility management or site supervisory system controller to extend its data to remote technicians in the field, a monitoring service, or a service department headquarters. With remote access, historic system data can be quickly accessed to analyze and troubleshoot errors.

Failure protection

One of the most obvious benefits of CoreSense technology is its ability to protect the compressor from damage, primarily through its system trip or reset functions, including:

  • Incorrect phase rotation protection (Scroll only)
  • Discharge temperature protection (optional on Discus)
  • Oil pressure protection (Discus)

In the event of a lockout condition that warrants compressor shutdown, CoreSense technology will stop the compressor until the event has been cleared by the contractor (either remotely or on-site). Fault alarm codes tell the contractor the source of the issue so they can begin troubleshooting. This not only saves retailers the cost of replacing a compressor, it saves contractors time by providing advanced diagnostics through troubleshooting apps to determine the root cause of the problem in preparation for repairs.

Advanced diagnostics

CoreSense technology gives contractors a wealth of historical system data that they can use, both for troubleshooting current issues or preventing system failures before they happen. Following is a partial list of faults and key performance indicators available:

  • Over current protection
  • Over/under voltage protection
  • Unbalanced load detection
  • Liquid Injection
  • Anti-short cycle time delay
  • Digital fault code display/remote alarming
  • Locked rotor protection
  • Motor overheat protection (Discus)
  • Welded contactor protection (Scroll)

On-board compressor diagnostics make good sense

While the emergence of compressor electronics may present a learning curve for some contractors, there’s no questioning their benefits. Technicians can leverage the wealth of information available at the compressor to evaluate the entire refrigeration system. Not only does CoreSense technology allow contractors to analyze and perform key actions remotely, it also gives them the tools to quickly and accurately diagnose system issues and conduct more productive s

Simulation Model Breaks the Ice on Meeting Efficiency Targets

This blog is a summary of the article Simulation Model Breaks the Ice on Meeting Efficiency Targets from our recent edition of E360 Outlook. Click here to read the article in its entirety.

System simulation models have been widely used for decades to help commercial refrigeration equipment manufacturers test the impacts of various components and design options. By simulating the steady-state operation of the vapor-compression cycle, these models have served as the basis of predictive evaluation in many modern refrigeration applications. Engineers rely on these virtual models to expedite the design process and test prototypes before proceeding with physical equipment development. This has not been the case with ice machine simulation models … until now.

The transient nature of ice machine operation — continually cycling between ice formation and harvest modes — presents challenges in simulating the effects on the system during these transitions. That’s why developing a usable simulation model for the evaluation of ice machines has been historically problematic. It’s also why our engineering team at the Helix Innovation Center decided it was time to tackle this challenge head-on.

The release of this simulation model has timely implications for automatic commercial ice maker (ACIM) manufacturers. In 2015, the Department of Energy (DOE) revised its efficiency standards for machines that produce 50–4,000 pounds of ice per day. The ruling will take effect on Jan. 1, 2018, requiring ACIMs manufactured after that date in the United States to reduce energy consumption by 10–15 percent1.

Since ACIMs are produced in a wide range of capacities and used in restaurants, hotels, convenience stores and hospitals, compliance to the new standard has broad industry implications. The ruling affects the two primary classes of ACIMs: batch ice machines (aka “cubers”); and continuous ice machines (aka “flakers” and “nuggets”).

With the new DOE standard taking effect in a little more than a year, many ACIM manufacturers have either already begun or are planning to kick off the engineering design cycle. Our new ACIM simulation model is available to help our customers meet this fast-approaching deadline.

Rapid prototyping

The ACIM simulation model will enable engineers to perform rapid “what if” analyses, allowing them to quickly evaluate the impact of a variety of system design options, including:

–    The size of the air-cooled condenser and finned surfaces
–    Changes in air/water flow rates, as well as ambient air and inlet water temperature
–    Compressor capacity and/or efficiency during freeze and harvest cycles
–    Evaluation of alternative refrigerants
–    Suction/liquid line heat exchanger
–    Thermal expansion valve properties

To verify the validity of simulation data, results from the model were compared with the experimental data of a standard 500-pound capacity ice machine, operating under various ambient air and water inlet temperatures. Key measures of the ice machine’s performance include: cycle time (duration of freeze and harvest cycles); energy input per 100 lb of ice; and energy usage during a 24-hour period. Against these measures and in a variety of operating conditions, the model achieved accuracy levels within 5 percent.

Now that it’s established, the ACIM simulation model enables the prediction of component performance, evaluation of loads under different operating conditions and assessment of system design changes — all within a virtual environment. We’re looking forward to working with our ACIM OEM partners to help them achieve the efficiency levels set forth by the DOE.

The food retail industry is constantly evolving. Retailers are faced with shifting consumer demands, intense competition, razor-thin profit margins and changes to store formats.  Many retailers are seeking flexible infrastructures to meet these needs without sacrificing sales or increasing costs.

Integrated facility controls and remote monitoring services provide the best visibility into system performance across an enterprise of stores. In addition, remote monitoring allows precise tracking of store conditions and issues alerts when equipment is not operating properly.

With a centralized facility management platform and actionable insights through monitoring services, HVACR contractors can assist retailers with attaining operational improvements through proper equipment maintenance, efficient service and actionable insights.

Here are some of the benefits you can offer to your retail partners:

Quicker more efficient installations
For contractors, implementing installations correctly the first time is the best way to secure and maintain a relationship with food retail clients. Integrating all store equipment into the existing management systems through the latest connected technology is a great solution for retailers.

Remotely update equipment
HVACR contractors have the ability to access facility systems to remotely manage settings, software and firmware updates through IoT, rather than manually onsite. Connected facility management systems can be updated remotely ensuring consistency and accuracy across an enterprise of stores.

Decrease unnecessary service calls
HVACR personnel can log into the software to view the status of various connected equipment and work to solve problems in real-time. In some cases, they can fix the issue remotely, reducing trips to the store.

Effective dispatch of experienced technicians
In the event of a service issue that requires an HVACR contractor visit, clients can be sure that knowledgeable, experienced technicians will fix their equipment issues. Because of alarms, the technicians will know the proper equipment to bring to resolve the issue and can work on multiple system issues at one time.

Food retailers with multiple sites are usually stretched pretty thin. Working with qualified HVACR partners to implement the latest integrated facility management systems will help retailers make better informed decisions for operational improvement.
