Emerson’s Commercial & Residential Solutions Business

June 26 is annual World Refrigeration Day: a day when the world recognizes the significant role that refrigeration plays in modern society. This year’s theme is “cooling matters”; at Emerson, we couldn’t agree more. World Refrigeration Day is a chance for us to reflect on the current state of the HVACR industry, the mega trends impacting the global refrigeration landscape, and how we’re helping to develop and advance ever more reliable and sustainable cooling technologies.

Refrigeration sits at the intersection among three environmental megatrends impacting our world today:

  • Phasing down the use of hydrofluorocarbon (HFC) refrigerants with high global warming potential (GWP)
  • Improving the energy efficiency of commercial buildings
  • Reducing food waste while increasing global food security

Supporting next-generation refrigeration technologies

In commercial refrigeration, the HFC phasedown and equipment energy consumption are two key factors in lowering greenhouse gas (GHG) emissions, through what we refer to as the total equivalent warming impact (TEWI). Refrigerant leaks are direct contributors to GHG emissions, which is why each refrigerant has a relative GWP rating; the higher the GWP rating, the worse the direct GHG impact. The energy consumed by a commercial refrigeration system is considered an indirect contributor to GHG emissions. Combined, these direct and indirect emissions make up a system’s TEWI.

Commercial refrigeration stakeholders are becoming ever more focused on lowering their carbon footprints by reducing these direct and indirect GHG emissions. Many of our customers are setting Net Zero targets and pledging to meet both near- and long-term decarbonization goals. U.S. regulatory mandates are taking shape that will help to drive our industry toward achieving these goals.

At Emerson, we’re committed to leading the transition to lower-GWP, energy-efficient refrigerant technologies. We already have an extensive portfolio of CO2 and R-290 refrigeration components and system technologies to help our customers leverage these proven natural refrigerant options. We’re also actively preparing for the emergence of synthetic A2L refrigerants, which will fill a niche in commercial refrigeration by covering a wide range of applications. Regardless of which refrigerants align best with our customers’ operational and sustainability goals, we’re supporting equipment strategies to help them phase out legacy HFC systems and phase in their next-generation refrigeration technologies.

Today, an estimated 3.6 billion cooling units are in use globally — a figure that is expected to increase to 9.5 billion by 2050. Developing more energy-efficient cooling systems with the ability to optimize energy consumption, flex demand, and enable grid interactivity will be essential for achieving a greener future. Today, Emerson monitors over 70,000 refrigerated sites annually, underscoring the critical importance of our efforts to develop more sustainable ways to ensure essential cooling while minimizing peak energy consumption.

Preserving perishable foods

According to the U.S. Department of Agriculture, up to 40 percent of the total food supply is wasted in the U.S., with more than 30 percent attributed to food loss at retail establishments and consumer homes. To combat hunger, reduce GHG emissions at landfills, and maximize resource utilization, reducing food waste is among the most critical issues facing our world.

Perishable food preservation — in storage and in-transit — is the primary objective of our refrigeration efforts and cold chain business. We’re committed to reducing food waste through:

  • Reliable Copeland™ compression technologies
  • GO real-time tracking and monitoring devices
  • Lumity™ E3 supervisory control and software platform, and connected control devices
  • Internet of things (IoT) connectivity and data analytics

Our integrated solutions deliver maximum reliability and visibility to food quality and safety from farm to fork. We’re capturing the cold chain data that empowers our customers with the insights they need to extend the life of their perishable products, meet their sustainability goals, and drive bottom-line improvements to their businesses.

So as we observe World Refrigeration Day this year, let’s remember that “cooling matters” must also be balanced with sustainability efforts. At Emerson, this is an everyday guiding principle for our cold chain business.

Earth Day Decarbonization: Three Ways We’re Helping Customers to Reduce Carbon Footprints

         Greg Polce | Vice President of Marketing – Cold Chain

          Emerson’s Commercial & Residential Solutions Business

April 22 marks the 52nd anniversary of Earth Day — a day when the world pauses to reflect on the shared responsibilities of preserving our natural environment and reversing the negative impacts of climate change. This year, the Earth Day organization is calling for global governments, businesses and citizens to form partnerships and accelerate solutions focused on building more sustainable and prosperous futures. At Emerson, we’re committed to doing our part by helping our customers to achieve their short- and long-term decarbonization goals.

According to current estimates, 51 billion tons of greenhouse gas emissions (GHG) are released annually into the Earth’s atmosphere. As the demand for energy is estimated to double over the next 30 years, climate experts are prioritizing efforts to help reduce global carbon emissions to a net-zero footprint by 2050. Hitting these decarbonization targets will require a holistic re-evaluation of everything that contributes to harmful GHG emissions.

Emerson’s commercial and residential solutions play key roles in this monumental effort. Consider that 19 percent of total carbon emissions can be attributed to feeding the world, yet roughly one-third of the global food supply is wasted. Generating, delivering and consuming electricity (by plugging things in and turning them on) accounts for 27 percent of total GHG emissions.

Three paths to net-zero

When we look at our cold chain business, we’re embarking on numerous strategies to help our customers affect positive change and provide much-needed GHG reductions. It’s important to think of these strategies as interrelated efforts that work together toward winning the race to net zero.

  1. Reducing food waste (in storage and on the move)

Reducing food waste is a core value of our cold chain business, and we help our customers to achieve this through a combination of compression technologies, tracking/monitoring devices and software, and control devices. Energy-efficient Copeland™ compressors set the industry standard in reliability and are preferred in commercial refrigeration, transport and marine applications. They serve as the cooling foundation for supermarkets, restaurants and shipping companies seeking to preserve food quality and safety and extend perishable shelf lives.

We’re also helping our customers to achieve “farm to fork” visibility to their perishable cold chains. Our GO real-time tracking and logging devices, combined with Oversight software, allow stakeholders to monitor the temperatures and locations of in-transit perishable shipments in real-time. In addition, our customers can leverage a variety of control devices to monitor coolers, freezers and cold storage facilities. The data we’re gathering from each step is delivering the deep insights our customers need to continually refine and improve their cold chain management capabilities. Once food waste reaches landfills, our Vilter™ compressors are helping operators to convert methane gas to energy.

  1. Lowering carbon emissions (from equipment and systems)

Refrigeration is among the most important technological advancements contributing to human health and well-being. Because the compressors and components that power commercial refrigeration systems consume significant amounts of electricity, Emerson has always prioritized efforts to improve equipment efficiency and reliability. From energy-efficient compression technologies with variable-capacity modulation to dedicated smart controls for low-GWP refrigerant systems, we’re innovating the tools our customers need to minimize indirect GHG emissions (from systems being powered up).

Of course, direct emissions from refrigerant leaks are also a critically important sustainability consideration. Emerson has helped lead the industry’s transition to lower-global warming potential (GWP) refrigerant technologies, supporting the global phasedown of high-GWP hydrofluorocarbon (HFC)-based systems. By embracing the next generation of low-GWP natural and synthetic refrigerants — and supporting advanced leak detection programs —we’re providing the guidance our customers need to help align refrigerant decisions with their sustainability objectives.

By combining low-GWP refrigerants with energy-efficient refrigerant technologies, we’re helping our customers to reduce both their direct and indirect emissions, which lowers the total equivalent warming impact (TEWI) of their refrigeration footprints.

  1. Enabling grid interactivity (leveraging our install base to reduce consumption)

We anticipate that the trend toward electrification will impact the ways in which we live and conduct business over the coming decades. At Emerson, we see this as a tremendous opportunity to move the needle toward net-zero by empowering our commercial refrigeration customers with grid-interactive facilities. As demand increases over the next 30 years, the infrastructure supporting our shared grid will need to be upgraded to integrate more renewable, alternative and distributed sources of energy. Although this strategy is essential to achieving net-zero by 2050, experts expect intermittent supply challenges, especially during peak consumption periods.

Today, our customers represent approximately 30,000 MW of electrical load. With grid-interactive building management controls — such as our new Lumity™ E3 supervisory control system — we’re helping them to manage their electrical footprints in coordination with utilities to offset grid demand constraints and reduce energy consumption. This will allow companies to leverage their facilities’ refrigeration, HVAC and lighting systems as distributed energy resources (DERs) — a connected technology that responds to grid signals and/or requirements to generate or conserve energy.

Not only is this strategy good for decarbonization, but we see it as an opportunity to grow our customers’ bottom lines. By connecting to the grid and reducing consumption upon request — or temporarily flexing their loads to other sources — companies can monetize their DER contributions. And while this may seem like the next frontier of energy management, many of our customers are already receiving incentives from utilities for making energy-efficient equipment choices or acting as a DER.

At Emerson, we know that the transition to net-zero will not be easy and can present new challenges to our customers and served industries. But we’re committed to achieving Earth Day goals every day of the year and look forward to helping our customers make the shift to more sustainable refrigeration and flexible energy management strategies. We’ll continue to explore ways to reduce energy consumption, lower GHG emissions, and enable grid interactivity — without impacting critical refrigeration, heating or lighting requirements.

Emerson Highlights Commitment to CO2 at ATMO World Summit 2022

Andre Patenaude | Director – Solutions Strategy

Emerson’s Commercial and Residential Solution’s Business

Emerson recently participated in the ATMO World Summit 2022, a 24-hour event focused on exploring developments in the uses and applications of natural refrigerants. Emily Vilardi, Emerson product marketing manager and I presented a webinar highlighting Emerson’s commitment to CO2 refrigeration via the launch of new products and our expanded research and development (R & R&D) efforts. For those unable to attend the event or our session, ATMO has made it available for free on-demand.

Corporate sustainability objectives and environmental regulations are driving the adoption of refrigerants with lower global warming potential (GWP). As food retailers evaluate emerging solutions and transition to the next generation of refrigeration technologies, CO2 transcritical booster systems offer a proven, natural alternative. Although this innovative system architecture uses CO2 (refrigerant name R-744) for both medium- (MT) and low-temperature (LT) refrigeration loads, it introduces a whole new approach to refrigeration for many end-users and technicians.

Emily and I discussed how Emerson is committed to helping facilitate this transition by simplifying the application of CO2 refrigeration through the seamless integration of system components. We focused on three primary areas: compression and variable frequency drives (VFDs), controls and software, and R&D lab investments.

CO2 compression and VFD technology

For the MT transcritical portion of a CO2 transcritical booster system, Emerson offers the Copeland™ 4MTLS transcritical CO2 semi-hermetic compressor in nine displacements from 40,000 to 300,000 BTUs at 60 Hz. These four-cylinder compressors feature onboard diagnostics and have a capacity range from 17.5 to 354 MBH at 20 °F evaporating, 95 °F gas cooler outlet at 60 Hz. In addition, they can be paired with Copeland VFDs, EVM/EVH Series to enable variable-capacity modulation. EVM/EVH drives offer the security of providing 200 percent maximum overload protection for two seconds.

On the LT side, Emerson offers the Copeland ZO(D) subcritical CO2 scroll compressors: ZO for fixed capacity and ZOD (digital) for variable-capacity modulation or their ability to unload capacity down to 10 percent. For example, the ZOD34 is rated for a 34,000 BTU displacement that can modulate (or unload) its capacity to 3,000 BTUs. These subcritical digital scrolls offer a smaller, lighter-weight footprint and don’t require VFDs for capacity modulation. In addition, Copeland MSLS subcritical semi-hermetic compressors are available in displacements from 60,000 to 180,000 BTUs, have a range of 25 to 70 Hz, and are rated for very high standstill pressures.

Integrated CO2 controls

CO2 transcritical booster systems rely heavily on electronic controls to optimize system installation, integrate with cases and high-pressure valves (HPVs), and manage system pressures. Emily explained Emerson’s integrated approach to CO2 controls that enables seamless communication and enhanced visibility to all aspects of system operation.

The soon-to-be-released Lumity™ supervisory control for CO2 applications will expand upon the legacy E2e control to offer enhanced CO2 capabilities, reduce programming complexities, and simplify system management via:

  • Centralized CO2 suction group control for transcritical booster and parallel compression
  • Advanced compressor superheat management for liquid or hot gas injection
  • Precise load management and automatic recovery from out-of-range conditions
  • Enhanced CO2 system monitoring for system insights
  • Oil management for long compressor life

The Lumity E3-CO2 will also leverage the many benefits of the new E3 platform, including a built-in touchscreen, remote mobile access, and a greatly improved user interface (UI) that brings all critical CO2 system monitoring into one unified view. The control will integrate seamlessly with Emerson’s high-pressure controller and valve driver (XEV20), the soon-to-be-released Lumity CC200 case controller, the XM600 series case controllers, and leak detection devices (RLDS and MRLDS).

Investing in the future of CO2

In the ATMO webinar, I also elaborated on how Emerson is helping our customers to prepare for the future of CO2 refrigeration through continued lab investments and R&D efforts. In addition to the CO2 transcritical booster system that has been installed at The Helix Innovation Center since 2016, we’ve recently dedicated more than 100,000 square feet to a CO2-specific supermarket test lab in our facility in Sidney, Ohio. This new lab will be launched this summer and feature:

  • 18 display cases from five different manufacturers
  • Walk-in cooler and walk-in freezer
  • Dry gas and adiabatic gas coolers on the roof
  • Wide range of high-ambient system strategies
  • Ability to create a 100 percent false load to enable testing at any capacity

These advanced testing capabilities will give Emerson’s application engineers ample opportunities to measure and validate system performance across a full spectrum of application scenarios.
