Natural refrigerant adoption is on the rise in the U.S., and forward-thinking supermarket retailers are leading the charge. Driven by corporate sustainability objectives and the desire to achieve EPA and DOE regulatory compliance, some operators are turning to eco-friendly options like CO2 to reduce their carbon footprint. Such is the case with New Seasons Market, a northwestern U.S. grocer that was recently awarded the EPA’s GreenChill Platinum Certification in its newest store for installing a transcritical CO2 booster system.

In many ways, sustainability is in New Seasons’ DNA. They partner with local farmers, ranchers and producers to offer the best of the region, and sell homegrown, organic favorites along with traditional grocery store staples. With 20 locations in the states of Washington, Oregon and California, the chain’s recently launched 37,000-square-foot store in Mercer Island, Wash., was the first to earn this distinction from the EPA.

New Seasons partnered with its engineering firm to develop a natural refrigeration system that would meet the sustainability objectives for the new location. The system, which is based on the Hussmann Purity platform, features Emerson’s compression and system controls technology, including:

  • Transcritical CO2 rack — consists of six compressors — three of which are low-temperature Copeland Scroll Digital™ CO2 compressors — with digital capacity modulation to provide energy-efficient refrigeration for the entire store. The system is charged with 1,100 pounds of CO2 (R-744).
  • Roof-mounted gas cooler — a gas cooler utilizes energy-efficient, low-velocity, variable-frequency drive (VFD) fans to reduce overall energy usage.
  • Controls — An E2 RX refrigeration controller manages the system in conjunction with Emerson case controls in the store fixtures. These tools enable the ease of system setup while ensuring ongoing performance optimization, maintaining consistent temperatures throughout the store, minimizing product shrink and preserving food quality.

The EPA GreenChill Platinum Certification recognizes New Seasons’ efforts in revamping the store’s refrigeration system — an HFC system installed by the previous retailer at this location — to a CO2 architecture that reduced refrigerant emissions by at least 95 percent.

The success of the Mercer Island store has opened the door for additional CO2 systems. Their leadership is currently planning the construction of two new stores in 2018 that will also rely on transcritical CO2 booster system architectures.

JOIN US in Chicago, Ill., for our next free E360 Forum on Thursday, October 5 from 8 a.m. to 4 p.m. at the Chicago Marriott O’Hare hotel.

We’re excited to bring our next E360 Forum to the hub of the Midwest, Chicago, Ill. This is already shaping up to be another dynamic year for the HVACR industry, and we need your perspectives at this daylong event to make sense of the latest trends and developments. From the growing technician shortage and the introduction of new refrigerants to the dynamic regulatory climate and subsequent system design changes, we’ll explore the complex landscape that lies before us.

The day will be comprised of informative keynote sessions in the morning, leaving the afternoon open for you to choose from four content tracks of interactive breakout sessions. These are designed to give you a chance to get your questions answered and join in a dialogue with experts and peers.

Chicago’s breakout session tracks will focus on applications, regulations, air conditioning and industrial.


With your participation, the goal of this E360 Forum is to evaluate 2017’s trends and tackle the biggest challenges in commercial refrigeration and air conditioning.

What you’ll experience:

  1. Hear how the HVACR industry is addressing the growing technician shortage
  2. See the latest applications of natural refrigerants
  3. Review timely updates to energy and refrigerant regulations
  4. Learn about what’s on the horizon in the retail and foodservice sectors

E360 Forums have proved to be invaluable events, and we’re providing ample opportunities for you to have one-on-one discussions with experts and peers. Immediately following the breakout sessions, attendees and presenters can mingle at a networking reception from 4–6 p.m. And for those able to join us the evening before the event, we will host a welcome dinner on October 4 from 6–8 p.m. in the Chicago Marriott O’Hare hotel.

We hope you’ll be making plans today to add Chicago’s E360 Forum to your list of must-attend industry events in 2017.

Manufacturer Takes “Combined Design Cycle” Approach to Regulatory Compliance

The Department of Energy’s (DOE) 2014 ruling mandated 30–50 percent reductions in energy consumption on stand-alone commercial refrigeration equipment by March 27, 2017. For OEMs of stand-alone commercial refrigeration equipment, this placed them among the first to meet the task of compliance. But when you’re an OEM whose core principles are based on environmental sustainability — e.g., JSI Store Fixtures of Bangor, Maine — clearing these regulatory hurdles is just the cost of doing business. In fact, leadership at JSI seized this as an opportunity to revamp its refrigeration platform.

Eager to get out in front of the regulatory deadline, the OEM began working with its component suppliers in 2014 to begin the design, testing and DOE certification processes. At the same time, the Environmental Protection Agency (EPA) proposed the phase-out of commonly used hydrofluorocarbons (HFCs) in stand-alone commercial refrigeration equipment — a ruling that would become final in the summer of 2015 with a compliance date of 2019. Like OEMs, this presented a design dilemma for JSI: comply with each regulation separately or combine compliance efforts into a single design cycle.

By tapping Emerson’s regulatory stewardship and its expertise in compressor and electronic controls technology, JSI decided to tackle both DOE and EPA compliance requirements in the same design cycle. First, they worked with Emerson’s Refrigeration and Integrated Products group to develop an optimized, high-efficiency condensing unit that would serve as the basis of its wooden refrigeration fixture platforms.

The condensing unit features Emerson components, including: compressor, flow control and unit controller to facilitate tighter refrigeration control and an efficient assembly process into JSI’s refrigeration equipment. To make sure the new units met required energy objectives, JSI also utilized the DOE test validation and certification services of Emerson’s Design Services Network (DSN).

Completion of design, testing and certification

By the end of Q4 2016, JSI had completed the DOE certification process on 46 of its standard products, well ahead of the 2017 deadline. The effort required the commitment and dedication of the OEM’s strategic suppliers and partners, including an electronically commutated evaporator fan motor manufacturer, a third-party testing provider and Emerson’s DSN resources. In addition, JSI invested in an in-house testing facility where its units were ultimately rated for final certification.

To get out in front of the EPA’s HFC refrigerant ban in 2019, JSI opted to design its new stand-alone units to be “R-448A ready” — as the industry waits for the EPA to list new refrigerants R-448A/449A as acceptable for use through its Significant New Alternatives Policy (SNAP) program. JSI leadership made this decision based on a desire to align with the general direction the industry was heading and not impose difficult operating and servicing requirements on their customers.
