European Retailer Selects A2L as the Basis of Its Refrigerant Transition

As the transition from hydrofluorocarbon (HFC) refrigerants with high global warming potential (GWP) continues in the U.S., commercial refrigeration stakeholders are actively pursuing emerging low-GWP alternatives. Among these include a variety of synthetic and natural options, from A1s with a familiar footprint to mildly flammable A2Ls to the naturals A3 (R-290) and CO2 — all of which can meet very-low GWP thresholds but have varying characteristics which dictate system design architectures. In our most recent E360 Webinar, a leading European retailer provided details about how they chose an A2L refrigerant as the basis for their organization’s refrigerant transition.

Although A2L safety standards have yet to be finalized in the U.S., the case study presented by Brian Churchyard, senior manager of engineering and energy of UK-based ASDA stores, provided a useful framework for how U.S. retailers could follow a similar path to regulatory compliance and sustainable refrigeration. He detailed ASDA’s journey toward lower-GWP refrigeration, which ultimately concluded in the selection of A2L refrigerant R-454A with a GWP of 238.

Creating a new refrigeration design standard

Churchyard explained how ASDA formed a collective working group comprised of numerous agencies, private businesses and industry experts to conduct a detailed assessment of A2Ls. The group developed a design standard for the safe application of their chosen refrigerant, which was based on existing data from the use of R-290 (even though A2L flammability levels were well below those of R-290).

After comparing the performance of A2L refrigerants to other alternatives through numerous trials, the ASDA team concluded that their new design standard achieved their objectives of lowering capital investment, energy consumption, lifecycle costs and carbon emissions. It’s important to note that while R-454A does not have the lowest GWP of the available A2L alternatives, it offered performance improvements that helped to meet these sustainability goals while adhering to the EU’s F-Gas regulatory requirements.

Moving to an A2L also required a reduction in refrigerant charge, which dictated that ASDA would also need to transition from large, centralized rack systems to smaller distributed remote systems. Churchyard said that other benefits of a decentralized approach included limiting the potential for leaks while eliminating risk by having a single point of failure.

Focus on safety and leak mitigation

Of course, safety is a primary concern when using a flammable or mildly flammable refrigerant, and minimizing leaks was an essential part of ASDA’s design strategy. Churchyard stressed that leak prevention was a top priority in all their refrigeration system trials — whether it was an A1 HFC, CO2, hydrofluoroolefin (HFO) or A3 refrigerant. Preventing leaks not only minimizes the potential for emissions, but also ensures that the system is operating at full capacity and efficiency.

Churchyard said that in the event of a leak, display cases are equipped with a modular alarm system integrated into the case controller. If leakage is detected within a case, the system will activate an alarm that effectively triggers a shut-off valve that stops refrigerant flow to a particular display case. In addition, leakage thresholds are set at such a low level as to prevent the potential for A2L ignition. Quality inherent among system joints, connections and proper installation was a major collective focus of the new design standard, which included remote distributed refrigeration plants and their associated display cases.

Churchyard said case upgrades were often the first part of their refrigerant transition strategy. When store operators identified existing HFC cases that needed to be replaced, the first step was to upgrade to cases that were compatible for A2L use — even though they were still using an A1. Then, when the distributed A2L refrigeration plants were installed, these stores could safely transition over to the use of the R-454A A2L refrigerant.

ASDA has been leveraging this strategy since 2019, when it was recognized as the first retailer to adopt an all-A2L refrigerant strategy. To learn more details about ASDA’s successful refrigerant transition, please view this webinar.

The Helix: Bold Collaboration & Disruptive Innovation

Emerson’s Commercial & Residential Solutions Business

When Emerson first opened The Helix Innovation Center, we envisioned it as a catalyst to advance research and drive innovation for the global heating, ventilation, air conditioning and refrigeration (HVACR) industry.

In only a few short years, it has surpassed our best expectations, quickly becoming a place where industry experts can come together and work collaboratively to confront and solve some of the biggest challenges facing not just our industry, but our communities and the entire planet.

A perfect example of this is the work we’ve done at The Helix in regard to sustainable supermarket refrigeration. We recently introduced a new distributed scroll booster refrigeration architecture for retail operators that will help them meet their sustainability goals without introducing unnecessary serviceability complexities.

The Copeland™ scroll booster architecture helps reduce emissions from refrigeration systems by utilizing reduced charges of lower global warming potential (GWP) refrigerants and system design strategies that maximize energy efficiencies. It is designed for maximum application flexibility and optimized for use with a low-pressure refrigerant, R-513A.

This flexible architecture fills an urgent need within the food retail market, which is looking for commercially viable technology and equipment that not only delivers efficiency and simplicity, but also provides a positive impact on the environment. Until now, there has not been a single system architecture that addressed the wide range of sustainability objectives, as well as system cost and long-term serviceability considerations.

The combination of high performance, sustainability and serviceability made the distributed scroll booster an ideal choice for the Gem City Market, a new small-format supermarket that opened this April in a food desert in Dayton, Ohio.

The work being done at The Helix became a focal point for the project as Dayton community members, city officials and commercial refrigeration industry leaders came together to identify a solution that met the market’s configuration of the distributed scroll booster system that met the store’s unique footprint, floorplan and refrigeration requirements.

Special thanks to business partners Chemours and Hussmann, and my own company, Emerson, for donating expertise, resources and equipment for this important installation

This is a great example of why we built The Helix. There is no shortage of great ideas, innovative technology and dedicated commitment in the industry. Our innovation center provides an ideal place where are these elements can come together to achieve great things for our industry and our communities.

 

 

 

[New E360 Webinar] Preparing for the Safe Use of A2L Refrigerants in Commercial Refrigeration

RajanRajendran2 Rajan Rajendran | V.P., System Innovation Center and Sustainability

Emerson’s Commercial & Residential Solutions Business

The recent passing of the American Innovation and Manufacturing (AIM) Act is accelerating the phasedown of hydrofluorocarbon (HFC) refrigerants and renewing the search for viable refrigerant alternatives, including those classified as A2L (mildly flammable) and A3 (highly flammable). But while A2Ls are among the leading alternatives capable of achieving regulatory requirements, the safety standards governing their use in the U.S. have yet to be finalized. Our next E360 Webinar — which will take place on Thursday, May 27 at 10 a.m. ET/7 a.m. PT — will feature a panel discussion about how A2Ls have been successfully deployed in regions where they have already been approved.

Around the globe, the phasedown of HFC refrigerants is prompting a transition toward alternatives with lower global warming potential (GWP). While A2Ls and A3 have been approved for use in Europe and are now widely adopted in commercial refrigeration applications there, the development of safety standards is ongoing within the U.S.

Currently, several industry working groups are evaluating A2Ls and A3s in equipment and field applications, including UL 60335-2-89 (the equipment standard based on IEC 60335-2-89) and ASHRAE-15 (the application standard updated for commercial refrigeration based on ISO 5149) — both of which are approaching the final phases of approval.

Our upcoming E360 Webinar will explore one European retailer’s sustainability journey from HFCs to low-GWP A2L refrigerants. As part two of the Air-Conditioning, Heating, and Refrigeration Institute’s (AHRI) webinar series, How to Not Only Survive, but “Win” the Refrigeration Industry HFC Phasedown, this webinar will provide an opportunity for the U.S. to learn from their experience and prepare for a future with A2L refrigerants.

The webinar will include the following experts and practitioners:

  • Helen Walter-Terrinoni of AHRI
  • Lauren MacGowens of AHRI
  • Tim Anderson of Hussmann Corporation
  • Stephen Spletzer of The Chemours Company
  • Brian Churchyard of ASDA (a European retailer)

Attendees will learn about the key points of the European retailer’s journey:

  • Defining sustainability goals and objectives — and meeting them
  • Transitioning from A1s (HFCs) to A2Ls
  • Applying A2L systems in a safe and effective way
  • Understanding the impacts on store and equipment design, training and maintenance
  • Imparting lessons learned along the way
