For large retailers with multi-site store networks, there are significant advantages to using alarm management services and enterprise software — from reducing operational costs and preserving food quality and safety to lowering maintenance costs and improving energy efficiency. In a recent E360 Webinar, Best Practices in Enterprise and Facility Optimization, I talked with Scott Fritz, Emerson’s director of enterprise services & IT operations, about the keys to maximizing performance in these critical areas. View the webinar in its entirety and continue reading to learn more.

The process of managing assets, food inventories, service requirements and energy efficiency at an enterprise level involves a variety of stakeholders, including store managers, service technicians, alarm technicians, facility managers, energy managers and food safety managers. Companies need both the proper tools and strategies to effectively coordinate these resources and manage their collective efforts.

The following four best practices are designed to leverage enterprise software and services to help your company achieve its critical business objectives.

  1. Gain a centralized view of operations. Today, multi-site retailers are tasked with managing large asset and equipment portfolios — such as aging HVAC, lighting and refrigeration systems — and an ever-increasing number of “smart” assets connected via the internet of things (IoT). Enterprise software offers a centralized view and management of these critical assets, enabling remote support, user access controls and network-wide broadcast of changes (such as refrigeration and HVAC setpoints and lighting schedules).

By optimizing facilities management and controlling setpoint data, large enterprises — such as a supermarket with 250 sites — can achieve up to $1M annually in operational labor savings.

  1. Establish effective alarm management. Keeping a network of sites and their assets performing optimally requires the abilities to mitigate costly failures, save energy, and ensure food safety. But with virtually thousands of issues to sort through at any given time, this is no small task. Alarm management services allow companies to filter out the noise of countless non-essential alarms and prioritize critical issues. These timely and pertinent notifications accelerate issue resolution and prevent their potentially negative consequences.

For example, by avoiding food loss and delaying the “shrink” of perishable items, companies can save more than $2M annually.

  1. Enable remote access. Service technicians and maintenance teams are running increasingly lean, with a scarcity of available new talent to replace an aging workforce. Enterprise software enables remote field connectivity to service issues via intuitive software that can be accessed on handheld computers and mobile devices. Having access to this data helps technicians evaluate and troubleshoot issues remotely — often eliminating the need for service calls (i.e., truck rolls) — while serving as a real-time training tool for new technicians.

The reduction of unnecessary truck rolls and service calls across an enterprise can save up to $1.5M annually.

  1. Automate setpoint and energy management. Facilities managers are under increasing pressure to meet myriad day-to-day commitments — all while trying to achieve their profitability targets and reduce their liabilities and risks. Enterprise software with predictive analytics capabilities can help automate the compliance of critical operating parameters — such as refrigeration and HVAC setpoints — and deliver insights that facilities managers can leverage to make informed decisions.

By deploying setpoint management tools that ensure continuous commissioning of equipment and establishing processes to maintain optimal energy levels, companies can achieve up to a $2.7M reduction in annual energy spend.

By following these four best practices, companies can transform the productivity, energy efficiency and overall optimization of their enterprise operations. Emerson has the enterprise software, alarm management services and domain expertise to help large supermarket and restaurant chains optimize their multi-site store networks.

[Webinar Recap] Preparing for the DOE’s New WICF Energy-Efficiency Standards

Julie Havenar | Product Manager – Condensing Units
Emerson Commercial & Residential Solutions

I recently conducted an E360 Webinar about the Department of Energy’s (DOE) new energy-efficiency standards on walk-in coolers and freezers (WICF). The webinar was presented to help industry stakeholders prepare for compliance by reviewing the ruling’s scope, definitions and potential industry impacts. View an archive of the webinar here and/or read a summary of its key takeaways below.

Ruling overview

On June 3, 2014, the DOE published its final rule on prescribed performance-based standards for WICFs, which specifically apply to the condensing units and unit coolers used in these systems. Then, on July 10, 2017, the DOE issued an update to the ruling and released its minimum efficiency test procedures, which they termed the annual walk-in efficiency factor (AWEF).

AWEF is a metric created by the Air-Conditioning, Heating, and Refrigeration Institute (AHRI) designed to help manufacturers validate compliance. As defined by the AHRI 1250-2009 standard, AWEF minimum efficiency requirements for dedicated condensing units vary per capacity and application (e.g., indoor, outdoor).

Although the compliance date for medium-temperature, dedicated condensing system applications has been in place since 2017, the DOE has established the following enforcement dates for 2020:

  • 1: for medium-temperature WICF applications
  • July 10: for low-temperature WICF applications

Scope and definitions

The scope of the ruling pertains to enclosed WICFs that can be walked into and have a total chilled storage area of less than 3,000 square feet. In addition, the ruling applies only to those condensing units and unit coolers designed to provide one refrigerated load. Products designed and marketed exclusively for medical, scientific or research purposes are excluded from this ruling.

According to the DOE ruling, 32 °F is the point of differentiation between walk-in coolers and freezers. A walk-in cooler is defined as an enclosed storage space refrigerated to temperatures above 32 °F. A walk-in freezer is defined as an enclosed storage space refrigerated to temperatures at or below 32 °F.

The DOE WICF ruling applies to both new and retrofit refrigeration systems, including:

  • Condensing units that are assembled to construct a new WICF
  • Condensing units that are used to replace an existing, previously installed WICF component (retrofit)
  • Condensing units used within packaged systems

Important note: While this does mean that condensing units manufactured after the ruling’s enforcement dates must comply, it does not exclude wholesalers and contractors from using and stocking condensing units that were manufactured before the DOE enforcement dates.

Industry impacts

With the DOE enforcement dates quickly approaching, stakeholders throughout the commercial refrigeration industry need to understand the ruling’s potential impacts on their businesses. Of course, this starts with equipment manufacturers that must not only manufacture compliant products, but also demonstrate certification and compliance through the following: registration with the DOE’s Compliance Certification Management System (CCMS) database; proper disclosure in marketing materials; and permanent nameplate marking.

Impacts to other key stakeholders include:

  • Wholesalers — must be prepared for changing inventories and begin carrying only AWEF-compliant products if they are manufactured after the 2020 enforcement date
  • Contractors — must understand that if they replace a condensing unit with one manufactured after the DOE enforcement date, it must be an AWEF-compliant unit
  • Design consultantsmust be well-versed in the regulatory impacts to advise end users in the selection of energy-compliant, sustainable systems
  • End usersneed to consider selecting future-proof equipment that aligns with their long-term refrigeration strategies

Regardless of your specific role, Emerson offers additional training, resources and expertise to help you prepare for compliance and understand the impacts of the DOE’s WICF ruling. For more information, please view the webinar archive or download our DOE WICF ruling FAQ document.

GreenChill Hosts Emerson-led Webinar on Natural Refrigerant Architectures

AndrePatenaude_Blog_Image Andre Patenaude | Director, Food Retail Marketing & Growth Strategy, Cold Chain

Emerson Commercial & Residential Solutions

My colleague John Wallace, director of innovation, retail solutions, and I recently partnered with the Environmental Protection Agency’s (EPA) GreenChill program to present a webinar about making the transition to an effective refrigerant architecture. In it, we discussed leading natural refrigerant systems, centralized and distributed options, and the controls schemes that support them. What follows are the key takeaways from that discussion, which you can view here in its entirety — last bullet under ‘Webinar Archives’.

Over the past decade, the transition toward natural refrigerants has been driven by a combination of dynamic market trends, which include: global refrigerant and food safety regulations, rapidly changing consumer expectations and corporate sustainability goals. This historic transition has helped accelerate the adoption and investigation of “future-proof” natural refrigerant architectures.

Regulatory drivers of transition to naturals

In the U.S., the California Air Resources Board (CARB) has not only fully implemented the now defunct EPA rules designed to limit the use of hydrofluorocarbon (HFC) refrigerants with high global warming potential (GWP), it is also actively working to enact more aggressive measures that would greatly impact future refrigeration system architectures. One current proposal under review would take effect in 2022 and mandate the following:

  • Systems charged with more than 50 pounds of refrigerant must use an option that is less than 150 GWP
  • New refrigerant sales with less than 50 pounds of refrigerant must use an option that is less than 1,500 GWP

But California is not alone in these initiatives; there are currently 25 states in the U.S. Climate Alliance which have vowed to follow its lead.

Since natural refrigerants are among a very small list of viable options capable of meeting the above criteria, the commercial refrigeration industry is likely to see an increase in system architectures designed to utilize natural options. These include centralized architectures for larger-charge systems and distributed (or micro-distributed) options for smaller-charged system types.

Leading natural refrigerants

When we think of natural refrigerants in commercial refrigeration, we are typically referring to R-744 (CO2 aka carbon dioxide), R-290 (refrigerant-grade propane) and R-744 (ammonia). Let’s look at their unique characteristics and how they can be effectively utilized.

CO2 has proved very effective in both low- and medium-temperature applications and is typically found in centralized systems such as secondary, cascade and transcritical booster. Having been successfully deployed in commercial and industrial applications in Europe for nearly two decades, it has made significant inroads in North America in recent years.

CO2 is not a retrofit refrigerant and is intended for use only in new systems. System designers, operators and technicians need to be aware of CO2’s unique characteristics, particularly its low critical point, high operating pressures and standing pressure (power outage) considerations. It has a GWP of 1, which puts it in an elite class of environmentally friendly options.

Propane continues to experience a global resurgence as a viable, efficient and very low-GWP refrigerant choice. Its high flammability has traditionally limited system charges to 150g, which is why today it’s found primarily in stand-alone systems that operate efficiently with a low refrigerant charge — such as integrated display cases often utilized in micro-distributed applications. In Europe and abroad, the International Electrotechnical Commission (IEC) recently raised its charge limit to 500g; the U.S. conservatively remains at 150g. Also, propane is not a retrofit option and is intended for new systems designed specifically for its use.

With its superior thermodynamic properties, ammonia was a logical first choice for early refrigeration systems. However, its toxicity requires careful adherence to safe application procedures to ensure operator safety and customer well-being. Traditionally, it has been used in industrial, process cooling, cold storage and ice rink applications. Most recently, ammonia has been introduced into commercial applications via cascade systems that utilize lower refrigerant charges and isolate the ammonia circuit away from occupied spaces.

System controls to support natural refrigerant architectures

Because of the unique properties in these emerging natural refrigerant architectures, system controls are even more essential to ensuring efficient operation, troubleshooting and servicing. Generally, the controls are loosely coupled to the refrigeration architecture, often following either a centralized or distributed approach.

However, the expanding variety of natural refrigeration systems can also pose new challenges for operators trying to maintain controls consistency or access a unified view across different systems. Here, a supervisory system — with its ability to integrate different devices into a common user interface — ensures that all stakeholders can quickly and easily evaluate each refrigeration system. 

As regulations continue to evolve and natural refrigerant systems gain more acceptance, Emerson is prepared to help equipment manufacturers, system designers and end users utilize these very low-GWP alternatives in the development of efficient, user-friendly and economically viable refrigeration systems.
