Make the Upgrade to Digital

The use of a digital compressor as the lead compressor in a fixed capacity refrigeration rack is becoming a preferred method for supermarkets seeking to meet varying refrigeration loads. With the ability to modulate capacity from 10 to 100 percent, digital compressors are now being written into the design specifications of many big-box retailers.


Digital Upgrade Kit for Traditional Rack Systems

This option is also available as an upgrade to existing refrigeration systems that are based on traditional parallel rack architectures. Many technicians are being called upon to retrofit these systems with a digital compressor upgrade kit. Although there are some newer technologies and electronic controls involved with the transition, the upgrade process is relatively straightforward:

  • Identify the compressor
  • Verify the system controller
  • Choose the correct upgrade model
  • Select the digital controller
  • Install upgrade kit

Digital Technology Yields Indisputable Results

A single digital compressor with 10 to 100 percent capacity modulation enables continuous variable unloading that delivers immediate and significant benefits. While results vary per application, operators can expect improvements in three major categories:

  • Reduced compressor cycling — the average compressor cycling is reduced up to 50 percent, but some scenarios have seen cycle counts go from 900 starts per day to 12 starts across a four-day span
  • Improved temperature control — digital modulation is capable of temperature control within +/- 1 °F
  • Tighter suction pressure control — operating suction pressure ranges are significantly reduced, moving from double-digit suction pressures (psig) to single-digit levels

These results make an open and shut case for a digital compressor upgrade. As awareness of this option becomes more well-known, many supermarket operators will opt for capacity modulation using this relatively simple upgrade to their existing rack systems.

Other Methods of Capacity Modulation

The challenge of modulating capacity in centralized rack refrigeration systems is not a new one, and system designers have made several attempts to solve the problem. Though none are as effective as digital capacity modulation, technicians still frequently encounter uneven rack and variable speed drives.

One digital compressor per suction group can provide precise capacity modulation from 10 to 100 percent. The results are up to 50 percent reduction in compressor cycling, improved equipment reliability and precise temperature control.

Considerations for Cutting the Wire in Convenience Stores

This recent bylined article for Convenience Store News shares key benefits of implementing wireless solutions for convenience store facilities. Below is a brief summary.

Seventy percent of facility management system wiring is used for networking and sensors. Wireless network solutions can be a powerful tool to help convenience stores reduce operating costs, easily accommodate store layout changes and provide secure facility data transmission.

Wireless solutions can range from a simple in-store temperature monitoring solution to a complex, self-healing wireless mesh network, or even a cellular connection outside of the store.

Why should you consider wireless solutions for your convenience store operation? The full article takes a deeper look at three different applications:

Eliminate Wires and Reduce Costs: Single Point Sensing

The Helix Innovation Center Is Open for Business

The relentless pursuit of innovation has always been a staple of Emerson’s business model. We are at our best when we’re asked to solve tough problems and balance customer requirements within the larger context of industry-wide challenges. With the launch of The Helix Innovation Center in December, our ability to build upon this legacy just got stronger.

Located on the University of Dayton campus in Ohio, this 40,000 square foot facility blends the disciplines of technology and engineering — part academic think tank and part real-world test lab. It’s here where we’ll take a blank slate approach, utilizing a comprehensive suite of flexible resources to tackle current industry challenges and develop the solutions of tomorrow.

To accomplish this, we’ve installed five industry modules that simulate the following real-world environments:

  • Residential connected home — 2,000 square foot, fully functional two-story home built to Department of Energy specifications. Capable of simulating global weather and annual performance conditions, from -20 °F to 120 °F ambient temperature and 20 percent to 90 percent humidity.
  • Light commercial building — the facility itself serves as the light commercial module, with state-of-the-art HVAC and variable refrigerant flow systems. The facility is LEED certified by the U.S. Green Building Council.
  • Foodservice operations — 1,500 square foot restaurant features a fully functioning, licensed commercial kitchen capable of servicing up to 150 diners. Like the residential module, allows for complete control of ambient air and humidity for desired comfort levels.
  • Supermarket refrigeration — utilizes a CO2 transcritical booster system for refrigeration, HVAC and heat reclamation for hot water. Simulates a 2,500 square foot supermarket or convenience store retailer.
  • Data center — 1,000 square foot module replicates a data center’s precise temperature and humidity control requirements.

Each industry module is a separate entity with isolated power sources to enable discrete measurement of energy consumption in individual modules and their respective equipment. We’ve also equipped the innovation center with three industry learning labs, where we expect to host up to 600 visitors and trainees each year.

The Helix is under the direction of Dr. Rajan Rajendran, vice president of system innovation center and sustainability, and will reflect the collaborative spirit that’s characteristic of our E360 program. Rajan will also be contributing a new column to the E360 Outlook publication that will highlight a relevant module, system or project taking place at the center. Look for the first installment of Helix Highlight in the current edition, where Rajan takes a closer look at the supermarket module’s CO2 transcritical booster system. We look forward to sharing these stories with you and invite you to make use of this new industry hub of innovation.

Best Practices for Convenience Store Energy Management [Webinar]

More than 80 percent of energy usage in an average convenience store is the result of refrigeration systems, lighting and foodservice equipment. We recently presented a webinar on energy management solutions for convenience store operators, highlighting the benefits of facility management and the evolution of these systems, which have become more advanced to meet the needs of today’s operators.

A video summary of this webinar is included below:
