This blog summarizes an article from ACHR NEWS, entitled “Refrigeration Retrofits Offer ‘Cool’ Savings for Supermarkets.” Click here to read the article in its entirety.

The commercial refrigeration system is the biggest energy user in supermarkets, accounting for about 40 to 60 percent of electricity consumption, according to the Environmental Protection Agency (EPA). For food retailers, getting energy consumption under control is a top priority, and the refrigeration industry has stepped in with new, higher-efficiency equipment and technologies, such as advanced monitoring and control via the internet of things (IoT). However, for many retailers, virtually all their equipment is aging, and buying new equipment and systems across the board would be prohibitively expensive. But there is another path to saving a considerable amount of energy: targeted retrofits or upgrades to their existing systems.

Some energy-saving modifications can be simple and obvious, such as adding doors to cases. But at a recent Emerson E360 Forum, I explained how a systematic approach to retrofits and upgrades can identify savings throughout a store’s entire refrigeration infrastructure, particularly older, energy-demanding direct expansion (DX) centralized systems. It is a six-step process that reveals the primary causes of energy loss and, step by step, proposes energy-saving retrofits and upgrades to your system that can systematically reduce energy costs without breaking the bank.

  1. Conduct a baseline energy audit throughout the store by installing energy-monitoring equipment. These sensors help you analyze the existing energy signature of the entire store before you make any adjustments or retrofits, and will also be invaluable for future temperature monitoring and control to ensure food safety and quality.
  2. Recommission your existing equipment to factory specifications. This may include adjusting setpoints, superheat, suction pressure and other settings. In the process, any broken components can be repaired. This one step alone can result in energy savings of 18 percent or more.
  3. Upgrade your refrigeration technologies. One effective upgrade is changing discus compressors to digital compressors. This single retrofit can reduce compressor cycling, increase system reliability, and improve energy efficiency by 16 percent or more. Installing variable-frequency drives on condenser fan motors can save even more.
  4. Upgrade your HVAC system. Ambient store temperatures are major stressors on refrigeration systems. Consider upgrading rooftop units and adding demand-controlled ventilation and humidity controls. Integrating the rooftop units with the refrigeration system in the store is another option, creating a self-contained ecosystem that balances ambient and refrigeration temperatures for significant energy savings.
  5. Upgrade lighting and other renewables. Adding modern lighting technology lowers temperatures. Installing doors onto units lowers energy losses. Electronic case controls and expansion valves (EEVs) fine-tune equipment temperatures, while upgrading to electronically commutated (EC) motors lowers electricity consumption while improving equipment efficiency.
  6. Perform condition-based maintenance. Once you’ve migrated to these capital upgrades, it’s important to step up your regular maintenance intervals to continue your gains in efficiency and cost savings.

With these targeted retrofits and upgrades, you can systematically make your centralized DX system more effective in maintaining food quality and safety while simultaneously uncovering efficiencies that can result in significant savings.

Refrigeration Strategies for Enabling Flexible Merchandising

The practice of rotating inventory in customer-facing product displays is often referred to as “flexible merchandising”. In a recent E360 article, I explained how refrigeration equipment is becoming more mobile to help food retailers implement this strategy. Read the full article here.

In today’s competitive food retail markets, flexible merchandising strategies provide opportunities to give customers the sense that there’s always something new to discover. Whether to highlight seasonal offerings, promote flash sales or maintain a vibrant store appearance, it’s a proven method of keeping customers engaged and coming back. To implement this strategy, grocers need flexibility in their display cases with the ability to move and rotate offerings as needed. The challenge comes when these products need to be refrigerated, because many traditional refrigeration systems don’t support that desired flexibility.

Refrigeration fixtures will need at least some degree of mobility to be viable in a flexible merchandising strategy. But in many cases, refrigeration architectures are often inherently incompatible with a flexible approach. Many have fixed-case layouts where fixtures and piping are literally affixed into the store’s floorplan with pre-determined insets. Traditional centralized direct expansion (DX) refrigeration systems also don’t lend themselves to refrigerated display case flexibility.

What are your refrigeration options for flexible merchandising?

With changing retailer preferences and market trends in mind, there are several viable refrigeration architectures available today. Let’s look at a few.

Distributed — this strategy is based on installing outdoor condensing units (“OCUs”) that allow them to be strategically located outside of a facility to support the addition of spot merchandising cases. Often utilized by smaller-format stores, this approach makes it easier for operators to scale their refrigeration system to the needs of the store. Modern OCUs are quiet, energy-efficient and offer installation flexibility while leaving small physical footprints outside the store. Keep in mind that OCUs are typically installed to support refrigerated fixtures in different zones, so their flexibility is limited to a particular zone.

Micro-distributed — featuring display cases that have the compressors integrated within the case, this emerging system type is becoming more common, especially in smaller-format stores. To remove the exhaust heat, cases are connected to a shared water-cooled loop that’s directed to the roof of the facility. These systems utilize a variety of low-GWP refrigerants at low charges, including hydrofluorocarbons (HFCs), hydrofluoroolefins (HFOs) and hydrocarbons such as R-290. The integrated case with water loop design enables a greater degree of merchandising flexibility, but does not quite achieve true mobility.

Self-contained — for maximum merchandising flexibility, these display cases incorporate the entire refrigeration system within the case — essentially serving as plug-and-play refrigerated units on wheels. These smaller refrigeration systems typically do not require large refrigerant charges, and are designed to use a variety of low-GWP HFC, HFO and R-290 refrigerant options. For a large-format store with a centralized DX system, incorporating self-contained display cases is a logical means of achieving refrigerated case flexibility.

As refrigeration technologies evolve to address changing industry dynamics, look for emerging system architectures that will help retailers meet the needs for flexible merchandising and smaller store footprints.

Ensuring Freshness in Click-and-Collect Fulfillment

Click-and-collect fulfillment requires new or improved refrigeration strategies to ensure food quality and safety. I recently discussed these approaches for Progressive Grocer magazine. Read the full article here.

To meet consumer demand for convenience, many food retailers are entering the omnichannel arena with a click-and-collect, curbside pickup option. This new model comes with high consumer expectations, especially for maintaining maximum freshness of perishable items. As we know, even the slightest deviations in holding temperatures can quickly impact perishable freshness and negatively affect a grocer’s reputation. One bad experience can quickly erode consumer confidence, spread through word of mouth, and even inflict long-term damage on a brand.

But when executed properly, a positive click-and-collect fulfillment process can result in significant business expansion and a thriving new revenue stream. It’s important to realize that this popular fulfillment model can place unique stains on a refrigeration system, such as maintaining ideal temperatures and humidity conditions in the face of frequent cooler door openings. Ensuring success will mean implementing an optimum refrigeration strategy. Here are a few things to consider when selecting a refrigeration system for click-and-collect fulfillment.

Implement smart controls

Modern control systems are ideal for click-and-collect applications to help retailers manage food quality from the time it enters the store to when it’s delivered to a customer. Best-available solutions combine facility management and supervisory controls with user-friendly software and mobile apps to deliver always-on, remote temperature monitoring and comprehensive management of store systems and refrigeration.

These controls help operators keep temperatures low during active fulfillment periods and adjust setpoints back up during non-peak hours to save energy during low-use hours — maintaining optimal conditions for perishable freshness. Monitoring services can detect system performance issues early and notify designated store managers via mobile alerts, enabling them to make informed decisions and quickly take corrective actions.

Consider outdoor condensing unit flexibility

Click-and-collect refrigeration may require facility operators to update their current systems to support reliable cold-storage and staging areas. These systems must be robust enough to meet low- and medium-temperature requirements, but also flexible enough to address the unique demands of click-and-collect fulfillment.

Self-contained outdoor condensing units (OCUs) are ideal for adding refrigeration capacity to new cold-storage areas without affecting a facility’s existing centralized refrigeration architecture. Modern OCUs are also equipped to address difficult setpoint and humidity challenges.

OCUs have compact footprints that allow for greater installation flexibility while combining advanced components with onboard controls to help maintain precise temperatures in difficult operating conditions. Proven scroll-compression technology helps these units deliver consistent reliability across a wide range of capacities (from 0.75 to 17 HP) to meet a variety of operational requirements. Electronic expansion valves, digital compression technology and specialized load-matching algorithms enable precise capacity modulation to match compressor capacity to fluctuating refrigeration loads during peak delivery periods.

Condensing-unit controls provide demand-driven defrost cycles and humidity management to help combat repeated door openings of cold-storage rooms and refrigerated lockers. Seamless integration with facility management controllers enables remote monitoring, power management and predictive diagnostics to help operators quickly respond to, and even potentially preempt, refrigeration faults or disruptions in performance.

Click-and-collect represents a tremendous growth opportunity for food retailers as consumers continue to embrace online grocery shopping. To succeed in this competitive arena, earn customer loyalty and capture market share, retailers will likely need to delight their customers with every transaction. These refrigeration strategies can help retailers deliver a seamless click-and-collect experience by ensuring consistency, freshness and quality with every order.

  1. Natural Refrigerant R-290 Stages a Comeback in Refrigeration

Natural refrigerants such as propane (R-290) are not new to the scene. In fact, in the early 1900s, early refrigeration systems were based on naturally occurring hydrocarbons, which combined excellent performance with one noteworthy caveat: flammability. When non-flammable CFC refrigerants arrived in the 1930s, natural refrigerants took a back seat until the environmental consequences of CFCs became apparent. In the early 2000s, researchers took a new look at R-290 as a completely GWP-free, high-performance refrigerant for low-charge commercial refrigeration equipment.
