The relentless pursuit of innovation has always been a staple of Emerson’s business model. We are at our best when we’re asked to solve tough problems and balance customer requirements within the larger context of industry-wide

challenges. With the launch of The Helix Innovation Center in December, our ability to build upon this legacy just got stronger.

Located on the University of Dayton campus in Ohio, this 40,000 square foot facility blends the disciplines of technology and engineering — part academic think tank and part real-world test lab. It’s here where we’ll take a blank slate approach, utilizing a comprehensive suite of flexible resources to tackle current industry challenges and develop the solutions of tomorrow.

To accomplish this, we’ve installed five industry modules that simulate the following real-world environments:

• Residential connected home — 2,000 square foot, fully functional two-story home built to Department of Energy specifications. Capable of simulating global weather and annual performance conditions, from -20 °F to 120 °F ambient temperature and 20 percent to 90 percent humidity.

• Light commercial building — the facility itself serves as the light commercial module, with state-of-the-art HVAC and variable refrigerant flow systems. The facility is LEED certified by the U.S. Green Building Council.

• Foodservice operations — 1,500 square foot restaurant features a fully functioning, licensed commercial kitchen capable of servicing up to 150 diners. Like the residential module, allows for complete control of ambient air and humidity for desired comfort levels.

• Supermarket refrigeration — utilizes a CO2 transcritical booster system for refrigeration, HVAC and heat reclamation for hot water. Simulates a 2,500 square foot supermarket or convenience store retailer.

• Data center — 1,000 square foot module replicates a data center’s precise temperature and humidity control requirements.

Each industry module is a separate entity with isolated power sources to enable discrete measurement of energy consumption in individual modules and their respective equipment. We’ve also equipped the innovation center with three industry learning labs, where we expect to host up to 600 visitors and trainees each year.

The Helix is under the direction of Dr. Rajan Rajendran, vice president of system innovation center and sustainability, and will reflect the collaborative spirit that’s characteristic of our E360 program. Rajan will also be contributing a new column to this publication that will highlight a relevant module, system or project taking place at the center. Look for the first installment of Helix Highlight in this edition, where Rajan takes a closer look at the supermarket module’s CO2 transcritical booster system. We look forward to sharing these stories with you and invite you to make use of this new industry hub of innovation.

V.P./G.M., Refrigeration Marketing, Emerson Climate Technologies

A short 18 months have passed since

the EPA proposed its delisting rule

regarding today’s refrigerants. At

that time, members of Emerson Climate

Technologies’ senior team attended a

symposium at the White House to discuss

ways to mitigate the negative impacts of

HVACR technology on the environment.

The meeting concluded with all parties

pledging to take steps to reduce global

warming, and we laid out Emerson’s

specific plan to do just that. I am pleased

to report that we have kept our promise.As a company known for our

proactivity and planning, we were already well down the path of formalizing many sustainability initiatives, and the specific commitments we made were aligned with

those objectives. First, we committed to the construction of a global industry-accessible innovation center that would take on the biggest environmental and energy efficiency challenges affecting food retail, foodservice, commercial and residential buildings, and data centers. On December 17, 2015, the Helix Innovation Center opened on the University of Dayton campus, where we are beginning these pursuits toward a next generation of technologies.

Second, we committed to complete the development of several new products optimized for low-GWP refrigerants, as well as expand upon our efficient and sustainable CO2, propane and ammonia product lines. I am happy to report that we successfully developed new compressors, controls and flow components in 2015, utilizing natural and low-GWP synthetic refrigerants that are viable replacements for traditional HFC applications. We

also advanced our condensing units built around these class-leading core technologies, launching new products that enable significantly higher efficiencies while meeting refrigerant needs.

Our industry witnessed a whirlwind of regulatory activity in 2015, and these rulings are likely to continue throughout the near future. With the Helix Innovation Center open for business, it enhances our capability to collaborate with the entire value chain and respond to these requirements as they emerge. We’ve learned through the development of these products that as an industry of contractors, wholesalers, OEMs and consultants, we are all seeking to better understand how to apply and service new installations and manage the existing installed base of systems.

That is why we are even more committed to accelerating the E360 stewardship and exchange platform. To date, nearly 6,000 industry leaders and professionals have registered for these events. We are dedicated to hosting an objective forum — a place where ideas are presented and the challenges we face throughout the channel can be discussed and solved.

In October of 2015, the White House invited us to a follow-up meeting to report on our progress. While we were extremely pleased to present these accomplishments, we also pledged our ongoing commitment. It is our strong belief that environmental protection, global understanding of these sustainability measures and continued industry participation are all required to meet our shared challenges and objectives. Emerson Climate Technologies is dedicated to continuing its support for these efforts through our commitment to providing innovative products and ongoing industry stewardship.

The True Costs of Refrigerant Leaks

For decades, refrigerant leaks have been

considered an inevitable yet unfortunate

consequence of operating typical

supermarket refrigeration systems. Often

thought of as a cost of doing business,

refrigerant leaks and their far-reaching

impacts are largely underestimated.

According to the EPA’s GreenChill

research,1 the average supermarket has

two to four refrigeration racks charged with

approximately 3,500 pounds of refrigerant,

of which approximately 25 percent — or

the equivalent of 875 pounds — is lost

each year to leaks.

With increased consumer, business

and regulatory focus on minimizing the

environmental impacts of hydrofluoro-

carbon (HFC) refrigerants, food retailers

are recognizing the importance of reducing

refrigerant leaks through effective leak

detection practices. But aside from the

obvious environmental concerns, these

leaks are also cutting into retailers’ profits.

Even in a more moderate scenario

with a lower leak rate of 20 percent, the

economic costs cannot be ignored. For an

individual store, the loss of 700 pounds

of R-404A (arguably the most common

refrigerant in use today) at $7 per pound

equates to an annual expense of nearly

$5,000. Note that refrigeration racks and

cases are where refrigerant leaks are most

likely to occur.

Across a chain of 100 supermarkets,

this impact becomes much more signif-

icant, costing the same retailer nearly

$500,000 annually on lost refrigerant.

This doesn’t include the associated labor

costs or the potential loss of business due

to service disruptions in response to fixing

a refrigerant leak.

This 100-store scenario also reveals

the true environmental impacts: the nearly

70,000 pounds of leaked refrigerant is

equivalent to 124,500 metric tons of CO2,

the emissions of 24,000 cars or 10,600

homes. Refrigerant leaks also affect

equipment performance, causing systems

to run harder to compensate.

While this example may not be

representative of your exact scenario,

we encourage everyone to calculate the

impacts of refrigerant leaks in their

systems. The EPA has provided financial

calculators to help with these estimations.2

Before implementing strategies to

reduce refrigerant leaks, it’s important we

fully understand the regulatory landscape

to better align our efforts with existing

and proposed regulations.

Increased Regulatory Focus on Leak Detection

Existing Section 608

The EPA introduced Section 608 as part

of the Clean Air Act (CAA) in the 1990s to

address emissions of ozone-depleting

substances (ODS) such as chlorofluorocarbon

(CFC) and hydrochlorofluorocarbon

(HCFC) refrigerants used in stationary

refrigeration and air conditioning. The

main tenets of the ruling are designed to

ensure proper use, handling and disposal

of these refrigerants, including:

• Prohibiting venting

• Requiring technician certification

• Providing for safe disposal

• Mandating accurate record keeping

• Requiring corrective actions for leak

rates greater than 35 percent

According to the EPA’s Section 608

fact sheet,3 the agency is authorized to

assess up to $37,500 in fines per day for

any violation of these regulations.

California Air Resources Board (CARB)

The California Environmental Protection

Agency is historically a forerunner in

environmental initiatives, and their CARB

refrigerant management program4

designed to reduce leaks and emissions of

high-GWP refrigerants is no exception. The

ruling builds upon the EPA’s Section 608

regulation and introduces new measures to

promote effective management of refrig-

erants and minimize leaks, including:

• Requiring periodic leak inspections

and follow-up actions

- Registration, record keeping and

reporting

• Categorizing refrigeration systems by

refrigerant charge

- Small: 50 to 200 pounds

- Medium: 200 to 2,000 pounds

- Large: > 2,000 pounds

Aside from the obvious environmental concerns, these leaks are also cutting into retailers’ profits.

• Mandating Automated Leak Detection

(ALD) equipment for large systems

- Direct or indirect methods acceptable

According to the ruling, “if the large

refrigeration system is indoors and oper-

ates, or is intended to operate year round,

an ALD device is required.” 5 I will explain

the emergence and application of ALD

technologies later in this article.

SNAP Proposal to Section 608

In October 2015, the EPA announced a

significant new alternatives policy (SNAP)

proposal to amend Section 608 of its CAA.6

It incorporates some of the key elements

of the CARB initiative and lowers the leak

rate threshold for penalties. Among the

highlights of the proposal include:

• Reducing the leak detection threshold

from 35 percent to 20 percent in

industrial process and commercial

refrigeration systems containing more

than 50 pounds of refrigerant6

• Requiring regular leak inspections or

continuous monitoring devices, including

quarterly inspections for systems contain-

ing at least 500 pounds of refrigerant

• Prohibiting the operation of systems

normally containing 50+ pounds of

refrigerant that have leaked 75 percent

or more of their full charge for two

consecutive years

• Mandating that technicians keep a

record of refrigerant recovered during

system disposal in smaller systems with

5–50 pounds of charge

• Extending the requirements of the

refrigerant management program to

cover substitute refrigerants, such as

hydrofluorocarbons7

As with all SNAP proposals, the EPA

encouraged the industry to submit public

comments to the federal register. We

don’t yet know when the final rule will be

announced, but given its alignment with

the CARB regulations, the proposal

will likely lower the leak threshold and

recommend automated monitoring or

more frequent leak inspections.

Key Elements of Effective Leak Detection Programs

Accurate detection methods, reliable

notifications and continuous monitoring

are the key elements in an effective leak

detection program. When developing your

program, your aim should be to not only

establish proper leak detection response

protocols, but also institute proactive

measures to minimize or eliminate

leaks altogether.

Detection — an effective program

starts with detection. There are differing

technologies available depending on your

requirements, and I will address these in

the last section of this article. But installing

devices in the locations most likely to

produce refrigerant leaks — particularly

racks and cases — is as equally as important.

Notifications — ensure that the

correct individuals in the organization are

alerted when a leak has occurred. Alarms

are typically remote, local or a combination

of the two. Most remote notifications are

tied into the store’s energy management

system that will alert a technician or

monitoring center to ensure that the leak

is handled correctly.

Continuous monitoring — is one

aspect that is often overlooked. By

recording and analyzing the data around

leak events, retailers can correlate the

leaks with different types of equipment

or maintenance events. In doing so, they

can identify problem areas, develop more

effective leak detection programs and

improve their overall operations.

Finally, it’s important for retailers

to remember that there are many

operational benefits of early leak

detection. While most refrigeration

systems are designed with enough

capacity to offset the short-term impacts

of a small refrigerant leak, even a small

leak will significantly degrade performance

and capacity over time. Left undetected,

this leak could impair the refrigeration

system’s capacity to maintain proper

cooling. At that point, not only have you

lost refrigerant and compromised system

performance, you’re also faced with the

cost of potential food loss.

Leak Detection Technologies

There are several continuous monitoring

equipment technologies available to help

retailers automate the leak detection

process, meet CARB’s ALD requirements

and ensure future Section 608 regulatory

compliance. The technology falls into two

primary categories, direct and indirect,

and there are pros and cons of each leak

detection method.

Direct leak detection — directly monitors

the concentration of refrigerants in the air.

Direct technologies can be fixed or portable,

with fixed systems having a dedicated piece

of hardware installed on-site to detect

refrigerant leaks. Because fixed leak detection

systems can be connected to a facility’s

energy management system to enable

remote monitoring and notifications, they

are good candidates for meeting the CARB

ALD requirement. Fixed systems include

both active and passive technologies:

• Active — centralized system with sniffing

technology that utilizes tubing connected

to multiple zones. The central unit takes

air samples from zones to determine if

there is refrigerant present in the air.

• Passive — zone-specific hardware with

infrared technology placed in the specific

areas where sensing is desired. There are

no moving parts and generally require

less maintenance than an active (tubing)

system. If you need to sample a lot of

different areas in a single location, this

may become cost prohibitive.

Indirect leak detection — monitors and

interprets the status and operation of the

entire refrigeration system to determine if

leaks are occurring. This method typically

uses existing sensors and hardware and

does not require dedicated leak detection

hardware to be installed on-site. Indirect

technologies analyze refrigeration system

data — such as temperatures, pressures,

liquid levels and ambient conditions —

against performance algorithms and

historical data to evaluate system status.

While this method has the advantage of

not requiring location-specific sensors,

it may not be capable of pinpointing the

exact location of a leak. It is, however,

also considered a suitable method for

complying with CARB’s ALD requirement.

Each method has specific advantages

and offers retailers viable options to help

meet their leak detection objectives. Some

have even combined direct and indirect

leak detection systems to benefit from the

best of both technologies.

Conclusion: Leak Detection Makes Good Business Sense

With the renewed regulatory focus on

reducing refrigerant leaks, retailers are

taking a closer look at developing effective

leak detection strategies. Through the

help of ALD devices, retailers can achieve

continuous monitoring, satisfy reporting

requirements and reduce the need to

perform manual inspections.

But achieving compliance with current

or future regulations is only one benefit.

When you examine the cost of lost refrigerant,

the degradation of refrigerated system

performance and the potential for eventual

food loss, the business case for implementing

effective leak detection programs is as

clear as refrigerant-free air. To maximize the effectiveness of leak detection programs, retailers should

clearly communicate the importance of detecting and minimizing leaks across

their organizations. Here are a few best practices to achieve that goal:

• Establish a zero-tolerance policy for refrigerant leaks

• Focus on the potential for cost savings

• Utilize automated leak detection devices

• Correlate leaks to equipment

• Analyze data to detect trends and decide on corrective actions

• Institute proper maintenance procedures

• Inform and educate with available resources

State of the Art Sustainability

Multiplex Refrigeration System Lays Foundation for Café’s Green Mission

SU C C E SS S TO RY

If you’re a restaurant owner who decides to put the word

“green” in your name, sustainability better be a significant

part of your culinary story. After all, when patrons dine at

a green restaurant, their standards are raised. They expect

locally sourced, natural, organic and sustainably raised foods.

And they want a dining experience in an environment that exudes

green and supports sustainable principles. The Green Sage Café

in Asheville, N.C., embraces this challenge with a green vision that

permeates every facet of their operation.

Owned and operated by Randy Talley and Roger Derrough,

the Green Sage Café has three locations across Asheville. While

their first café incorporated many green elements, its refrigerated

fixtures each operated on independent compressors — a refrigera-

tion architecture that Talley identified as an area for improvement

in their second restaurant.

“With 10 compressors running on everything from under-

counter sandwich stands to reach-in refrigerators, there was a lot

of heat being generated and energy wasted, not to mention a

lot of noise rattling around the restaurant,” he said.

Talley leaned on his background in the natural foods grocery

industry to find a better solution. There he had utilized rack refrigeration

systems with minimal compressors to provide cooling for multiple

fixtures. He wanted to implement a similar architecture — now

commonly referred to as multiplexing — but wasn’t sure if this tech-

nology would translate into his foodservice applications. That’s when

Talley tapped Refrigeration Design Technologies (RDT), experts in

eco-friendly refrigerated system design, to implement a system that

would take his second location to the next level of energy efficiency.

“Our goal was to create the greenest restaurant possible.

We wanted to cut energy consumption in half without compro-

mising the quality of the food we’re serving,” Talley said.

Keeping (Eco)-Cool Under Pressure

Brent Dyess, RDT’s president, knew that Talley’s lofty goals were

within reach. Dyess selected RDT’s proven Eco-Cool refrigeration

system based on the Copeland Scroll Digital™ compressor for

the second Green Sage Café location. Eco-Cool was specifically

designed to meet the demands of environmentally responsible

foodservice outlets, relying on lean multiplex refrigeration

architecture to deliver the highest degree of energy efficiency.

The Green Sage Café’s unique energy and environmental

requirements made it an ideal candidate for the Eco-Cool

system. The system minimizes the compressors needed to

provide refrigeration, servicing eight fixtures in the café’s

medium-temperature suction group with one 4 HP Copeland

Scroll Digital compressor. With their ability to digitally modulate

capacity from 10 to 100 percent, the Copeland Scroll Digital

enables precise matching of refrigeration requirements to the

variable operating loads typical of a foodservice application.

Dyess ensured Talley that the benefits of this multiplex

architecture would be immediately apparent.

“Instead of eight compressors kicking on and off, pulling

full run-load amps each time, you have a single compressor

running at only the capacity needed to meet the load. And if

all fixtures call for refrigerant, that compressor is capable of

handling everything at the same time,” Dyess explained.

The medium-temp fixtures covered by the 4 HP Copeland

Scroll Digital compressor included:

• Walk-in cooler • Griddle stand

• Sandwich stands (2) • Product merchandiser

• Reach-in refrigerators (2) • Beer cooler

Dyess explained that the digital application also substantially

reduces the piping required in conventional systems. “Considering

we have eliminated numerous one-to-one piping scenarios, we can

run piping in a more efficient trunk line configuration,” he said.

Surprising Energy Savings

Dyess originally estimated that the system would provide the

restaurant up to 30 percent in annual energy savings. But when

“Our goal was to create the greenest restaurant

possible. We wanted to cut energy consumption in half without compromising the

quality of the food we’re serving.”

the Green Restaurant Association (GRA) evaluated the Green

Sage Café’s environmental profile for certification purposes, they

commissioned RDT to perform an independent, third-party study

on the Eco-Cool system. The results were surprising.

The UL energy study simulated a foodservice application,

comparing a multiplex system (with one Copeland Scroll Digital

compressor servicing six fixtures) to a conventional system. The

study replicated actual foodservice conditions, such as varying

demands and frequent refrigerator door openings and closings. The

data revealed that in 90 °F ambient conditions, the Copeland Scroll

Digital-based Eco-Cool system delivered 48 percent energy savings.

The study demonstrates that as the ambient temperature

rises above 90 °F, the energy savings will decrease slightly. But as

Dyess explained, at temperatures below 90 °F, the potential for

energy savings will continue to rise above the 48 percent mark.

Keeping Cool and Getting Into Hot Water

The multiplex refrigeration system also helped Green Sage Café

owners check other significant items off their sustainability list.

By placing the Eco-Cool unit outside the restaurant and removing

condenser surface areas that are present on each fixture in

conventional systems, they eliminated 53,856 BTUH of heat, or

the equivalent of 4.5 tons of air conditioning. Not only does this

contribute to the café’s eco-friendly footprint, it helps create

a better dining experience for patrons and improved working

conditions for the staff.

Another advantage of the Eco-Cool refrigeration system was

its ability to capture waste heat and divert it into a heat exchanger

that provided heating for the restaurant’s hot water tank.

“We had used solar panels for hot water heating in our

first location, but this heat reclamation system was even more

effective,” Talley explained. “This system takes care of all of our

hot water requirements,” he added.

For the RDT team, the concept of heat reclamation just

makes good environmental sense.

“If our customers see the value in reusing a natural by-product of

the refrigeration system, then we recommend it,” Dyess said. “Green

Sage Café had the vision and commitment to utilize every available

natural resource,” he added.

10

Designed with a Copeland Scroll Digital compressor, the Eco-Cool system from RDT serves as a cornerstone of

the Green Sage Café’s sustainability strategy.

Certifiably Green

With the Eco-Cool refrigeration system as a green foundation, the

Green Sage Café incorporated additional sustainable elements,

including: solar panels, energy-efficient dishwashers and LED

lighting. In recognition of its sustainable, state-of-the-art vision,

the Green Sage Café earned the distinction of being the GRA’s

first four-star certified Green Restaurant in the South.

As a result of their success, many other restaurants in the

Asheville area have taken on the green mantel. And with the help of

grants from the state of North Carolina, 17 restaurants (including the

first two of the Green Sage Café’s three locations) are now offering

sustainable, natural food-based fare in Asheville. The city has become

such a bastion of green culinary principles that it was recently named

the country’s first Green Dining Destination by the GRA.

For more than a year, we’ve discussed

the Environmental Protection Agency’s

(EPA) actions to prohibit the use of

hydrofluorocarbon (HFC) refrigerants

in certain commercial refrigeration and

air conditioning applications, as well as

expand the list of low-global warming

potential (GWP) alternatives. But while

these actions have focused on U.S. and

North American initiatives, the move to

limit HFCs is also picking up steam on a

global level.

Last November at the 27th international

meeting of the Parties to the Montreal

Protocol in Dubai, United Arab Emirates,

Article 5 (developing) and non-Article 5

(developed) nations alike came together

and committed to reduce worldwide

greenhouse gas emissions from HFCs.1

The meeting concluded with an agreement

to phase down HFC consumption by

completing an amendment to the Montreal

Protocol in 2016.

It’s an important reminder that a

global commitment to responsible envi-

ronmental stewardship is nothing new.

First signed on September 16, 1987, the

Montreal Protocol treaty has served as

an example of decades-long cooperation

among world governments, industry and

the environmental community. With every

country within the United Nations charter a

signatory to the agreement, it is considered

one of the most effective multi-lateral

Montreal Protocol Commits to HFC Management Amendment

environmental treaties ever negotiated.

The original treaty’s first order of

business was to achieve a rapid phase-out of

ozone-depleting substances — particularly

chlorofluorocarbons (CFCs) — by replacing

them with HFC-based alternatives. While

scientists are projecting a full restoration of

the ozone by 2050,2 they are also cautioning

against the continued widespread global

use of HFC refrigerants due to their

environmental dangers.

As we know, HFCs are used in every-

thing from air conditioners and refrigera-

tors to foam insulation and fire protection

systems. And while the U.S. and the

European Union (EU) are well down the

path of phasing out HFC use in specific

applications, the demand for these

technologies continues to grow in

developing countries where they

provide added health, safety, comfort

and productivity benefits.

Because of this, the Parties of the

Protocol have considered the issues of HFC

usage and emissions for more than five

years. During this time, the EPA’s SNAP

rulings and the European Union’s F-Gas

regulations provided viable examples of

official policies to limit the use of HFCs.

This is important because it set a precedent

for responding to the global HFC challenge.

Private companies and industry

coalitions have already answered the call

to develop low-GWP technologies and

HFC replacement alternatives — and will

continue to do so in support of future

amendments to the Montreal Protocol.

The Alliance for Responsible Atmospheric

Policy is one such example.

Lennox International’s John Hurst, who

serves as the Alliance chairman, expressed

their commitment in a press release

immediately following the 27th meeting.

“We are working rapidly to set the

stage for an amendment to the Montreal

Protocol which we believe can most

effectively promote the availability of

low-GWP replacement compounds and

technologies,” Hurst said.3

The Montreal Protocol’s success was

founded on its reliance on sound scientific

reviews, ongoing technology assessments

and a funding mechanism to assist

developing countries. The Parties of the

Protocol’s decision to address the HFC

issue with an amendment in 2016 is

largely focused on helping developing

countries make the transition to low-GWP

technologies, while accelerating HFC phase-

down schedules in developed countries.

The amendment will likely contain the

following components:

• Technology conversion and HFC phase-

down schedules

• Financing for developing countries

• Possible exemptions for those in high

ambient temperature conditions

• Interim reviews to assess technologies

and progress

The history of the Montreal Protocol

demonstrates that once a reduction

schedule is set, industry responds with

rapid development and deployment of

alternatives.4 The Parties to the Protocol

agree on reduction schedules based

upon the knowledge available at the

time, and are asked to be open to

schedule modifications due to scientific

discoveries and/or technological

advances.

While the details of the amendment

are still unclear, it is certain that efforts to

phase down HFCs will soon have a global

driver. Many of us in the U.S. are already

in the process of reducing HFCs and

therefore have a head start in making this

transition. As negotiations continue to

take place throughout the year and an

amendment to the Montreal Protocol

is drafted, we will keep you updated on

its progress and the implications to

our industry.

Welcome to the first installment

of a new column that will

focus on the technologies,

emerging products and research projects

taking place at our recently opened Helix

Innovation Center. In this edition, we will

place the spotlight on the CO2 transcritical

booster system that, among many other

things, is providing refrigeration to our

supermarket industry module.

We installed a CO2 transcritical

booster system to anchor our supermarket

module for several reasons. It has the

potential to provide an efficient, eco-friendly

refrigeration source for medium- and

low-temp display cases, walk-ins and

freezers. But that’s only the beginning.

We designed our CO2 transcritical booster

system to not only meet the entire air

conditioning and heating needs of the

supermarket module, we’re also reclaiming

its exhaust heat for the facility’s hot water

and snow melt system beneath the sidewalks.

We also chose CO2 because we feel it

has the potential for much broader appli-

cations than what is commonly thought in

the industry today. Our system is designed

with the flexibility to demonstrate and

exploit these possibilities.

Real-World Simulation Evaluates the Viability of CO2 in Warmer Climates

CO2 transcritical booster systems have

gained wide acceptance in northern

climates throughout the world. As a

natural refrigerant with near zero global

warming potential, CO2 is becoming a

preferred option for retailers seeking to meet

sustainability goals and take regulatory

compliance out of the equation. But with a

critical point of 87.8 °F, special measures are

required to keep CO2 systems operating at

high efficiencies above this temperature.

This is the reason very few retailers

have attempted to deploy CO2 systems in

warmer regions. It’s also one of the limitations

with CO2 transcritical booster systems that

we are determined to eliminate.

One unique aspect of The Helix is its

environmental control chamber, located

just outside the facility. This chamber

serves each of the five industrial modules

on-site and is capable of simulating

operating temperatures between -20 °F

and 120 °F. So, if we want to measure how a

Exploring the Potential of CO2 Transcritical Booster Systems

The Helix Innovation Center utilizes a CO2 transcritical booster system that’s designed to accommodate medium-

and low-temperature requirements in the supermarket. The medium-temperature suction group is based on three

Copeland™ CO2 semi-hermetic compressors (Copeland 4MTLS), supplying cooling to the store’s refrigerated cases,

walk-in cooler and air conditioning.

For the low-temperature group, three Copeland Scroll™ CO2 compressors (Copeland Scroll ZO) — including one

Copeland Scroll Digital™ compressor (Copeland Scroll ZOD) to enable varying capacity modulation for the group —

supply cooling to the store’s frozen food cases and walk-in freezer.

CO2 Transcritical Booster System Profile for the Supermarket Module

CO2 transcritical booster system performs

in the middle of summer in a supermarket in

Miami, we can do that.

The great thing about our facility is

that we have the flexibility to control every

variable that contributes to refrigerated

system performance. This allows us to

simulate a year’s worth of performance in

one week from any location in the world.

And, we can use this space to solve problems

with rapid prototyping and evaluation of

new ideas.

For example, if we want to test one of

the available methods for increasing CO2

transcritical booster system performance

in hot weather, we have several options.

First, we have ample space left in our

medium-temperature suction group to

add a compressor and test it in a parallel

compression configuration. We could

install an ejector device to evaluate its

effectiveness in the CO2 refrigeration cycle

in real-world conditions. Or, we could

retrofit our gas coolers with adiabatic pads

to measure their ability to keep the CO2

system below its critical point.

Like every industry module in The

Helix, the supermarket is an entity unto

itself, meaning that the power coming

into the module is completely isolated.

This allows us to measure the power

consumed by the store on its own, while

further isolating the energy consumption

of any one piece of equipment. Because

everything is within this controlled

environment, we’re able to evaluate the

performance of the CO2 transcritical

booster system in the supermarket and

the larger building envelope.

What all this means to our customers

is that you now have a real-world test lab

for designing the ideal refrigeration system

for your supermarkets, simulating the

conditions and environments that are most

challenging without risking product loss

or potential damage to your brand. While

today the system is CO2 based, we have the

ability to change the refrigerant as well as

the system architecture. We hope that this

opportunity will only spawn new ideas and

open the doors to further innovation.

incorrect phase, high pressure, high

discharge temperature and compressor

overheating — but also before they occur.

X-Line 2.0 is always on alert for things

in the system that could cause problems —

liquid floodback, compressor short cycling

and low voltage conditions, for example.

The proactive diagnostics even protect

bearings from wear caused by flooded

starts. This level of protection and

diagnostics allows system issues to

be identified before case temperatures

rise and product is lost.

When a system issue is identified, the

on-board diagnostics and time-stamped

data log provide refrigeration contractors

an unparalleled level of information to help

quickly and accurately correct the system.

The advanced knowledge provided by

CoreSense has been shown to improve

service technician accuracy and reduce

call-backs.

As we have studied the effectiveness

of units with CoreSense technology compared

to units without CoreSense, we found a

75 percent difference (92–17) in accuracy

among entry-level technicians, and a 37

percent difference (100–63) in accuracy

among experienced technicians. Warranty

costs are also significantly reduced.

Increase Efficiencies

X-Line units utilize Copeland Scroll com-

pressors and contain variable speed PSC

fan motors, both of which are highly

efficient with industry-leading low noise

levels. The compressors are compatible

with the emerging class of newly approved,

low-GWP refrigerants — including R-450A,

R-513A, R-448A and R-449A — making

them compliant with new EPA standards

and eco-friendly. The fan motors optimize

air flow for maximum heat transfer and are

compliant with CEC and national standards.

The condenser’s sizing has been

optimized as well, with large coils and

integrated electronic controls, which,

when combined with the variable speed

fans, enable the unit to operate at

maximum efficiency. This design not

only meets the DOE’s annual walk-in

efficiency factor (AWEF) standards, it

also supports low-condensing operation,

which provides 15–20 percent energy

efficiency ratio improvements for every

10 °F drop in head pressure.

At test sites, users are saving 20

percent on average in energy costs with

X-Line 2.0 units compared to other units,

making it ideal for walk-in coolers and

freezers, reach-in display merchandisers,

and even new, outside-the box-applications.

See our energy savings calculator here: http://xjenergycalc.emersonclimate.com/

xjenergycalc/.

Maximize Uptime

X-Line’s electronic controls provide the

advanced diagnostics and complete

system protection to prevent catastrophic

compressor failures and accelerate the

repair process. By preventing damage that

would otherwise require a compressor

replacement, costly downtime is avoided

and repairs are unnecessary. The system’s

on-board diagnostics codes and data log

allow refrigeration contractors to quickly

and accurately diagnose system issues,

reducing downtime due to troubleshooting

and misdiagnosis.

X-Line’s communication capabilities

further enable advanced warnings and

improved uptime. By connecting the unit

to a site supervisory control — such as an

E2 controller or ecoSYS Site Supervisor

available from Emerson, or other controls

available from third parties — system

issues can be identified and scheduled for

repairs before leading to a system failure

or product loss. Some issues can even be

diagnosed and repaired remotely.

X-Line has many attributes that make it the most versatile and

flexible refrigeration unit available today:

• Lightweight — 30 percent lighter than other units, X-Line can

often be used when other units may require new roof

support structures.

• Quiet — at the low sound level of 55 decibels, X-Line units

are ideal in noise-restricted residential areas; they have been

installed only feet away from hotel windows, and even inside

big-box stores on top of refrigeration cases.

• Small footprint — allows the X-Line units to also be installed on

a wall, or reduces required space when mounting on a roof or on

the ground.

• Corrosion resistant — with galvannealed and powder-coated

steel construction, and a hydrophilic condenser fin coating, the

X-Line is resistant to the corrosive salt air of coastal regions.

• Extreme ambient conditions — large condensers and demand

cooling allow operation in up to 120 °F ambient, while a heated

and insulated receiver, condenser check valve, variable speed

fan, and low pressure control time delay allow operation

down to -40 °F.

• Operates with multiple refrigerants — compatible with

R-404A as well as many of the new EPA-approved refrigerants,

including: R-407C/A, R-448A, R-449A, R-513A, R-450A; makes

X-Line units suitable for both new equipment and service

replacement applications.

For years, the outdoor refrigeration

condensing unit has been the work-

horse of small- and large-format

food retailers. It’s called upon to endure

extreme climates and continuously

support walk-in refrigerator and freezer

operations.

With energy costs rising, corporate

sustainability goals increasing, and

embedded electronics and equipment

technologies emerging, many food

retailers are looking to add efficiency

and eco-friendliness to their refrigeration

checklist. The Copeland Scroll Outdoor

Refrigeration Unit (X-Line) is Emerson

Climate Technologies’ answer to those

questioning the long-term practicality and

viability of their refrigeration technology.

Addressing this need in the market is

not new to Emerson — X-Line units were

introduced to North America back in

2008. The new, second generation X-Line

(X-Line 2.0) builds upon the technology of

the original models to offer best-in-class

energy efficiency, uptime and flexibility,

all while providing advanced diagnostics

and protection from an integrated suite of

electronic controls.

Unique Proactive Diagnostics

What is most unique about X-Line 2.0

compared to others in the industry is the

comprehensive range of system protection

it offers. Based on a fully integrated

electronic control system that combines

pressure, defrost, electronic valve, fan

speed, diagnostics and communications

controls into one modular control,

X-Line 2.0 offers comprehensive control,

protection and smart store technology

that meets the demands of modern food

retail requirements.

Using our proven CoreSense™ technol-

ogy for Copeland compressors, the unit’s

controls and sensors are designed to provide

both proactive and reactive protection.

Issues are not only detected as they occur —

including problems such as lost phase,

The use of a digital compressor as the lead compressor in a fixed capacity refrigeration rack is becoming a preferred method for supermarkets seeking to meet varying refriger-

ation loads. With the ability to modulate capacity from 10 to 100 percent, a digital compressor gives operators many benefits:

• Precise matching of capacity to changing refrigeration loads

• Tight control over suction pressures

• Improved case temperature precision

• Reduced compressor cycling (on/off)

Digital compressors have proven so effective in providing capacity modulation that this strategy is being written into the design specifications of many big-box retailers.

Digital Upgrade Kit for Traditional Rack Systems

This option is also available as an upgrade to existing refrigeration systems that are based on traditional parallel rack architectures. Many technicians are being called upon to retrofit these systems with a digital compressor upgrade kit. Although there are some newer technologies and electronic controls involved with the transition, the upgrade process is relatively straightforward.

The typical scenario for a digital compressor upgrade is fairly predictable:

a) The supermarket operator has likely made several attempts to

improve control of product temperature or reduce compressor cycling. It’s common in these scenarios to see cycling rates in the hundreds per day with as much as 15 °F fluctuations in case temperatures.

b) Modifications to the equipment (typically via the rack controller) were unsuccessful: adjustments to narrow suction pressure resulted in excessive compressor cycling; adjustments to reduce compressor cycling produced a wide range of suction pressures and unacceptable fluctuations in temperatures.

These operating conditions present an ideal opportunity for a digital compressor upgrade:

a) Identify the compressor — the technician’s first order of business is to identify the fixed capacity, semi-hermetic or scroll compressor in the rack that is the best candidate for replacement. Ideally, the fixed compressor capacity needs to be equal to or larger than the next compressor in the stage sequence to prevent capacity gaps between compressor cycling.

b) Verify the system controller — the system controller must be capable of providing an analog signal to the digital controller. Most modern rack controllers are capable of providing analog output.

c) Choose the correct upgrade model — once the replacement compressor has been identified, Emerson Climate Technologies

CO N T R AC TO R CO N N EC T I O N by T I M U D E R M A N

Make the Upgrade to Digital

offers an upgrade kit per specific model (Copeland Discus Digital™ or Copeland Scroll™). Note: for semi-hermetic compressors that are less than four years old, technicians can perform a head modification to convert the compressor to digital.

d) Select the digital controller — the new digital compressor necessitates an additional interface controller to tie into the rack system’s master controller. Emerson offers controllers for these specific applications.

e) Install upgrade kit — often the greatest apprehension about the upgrade process is the wiring required to tie into the interface controller, even though the process is fairly straightforward. The length of time required to install depends on the technician’s experience and electrical familiarity.

Digital Technology Yields Indisputable Results

A single digital compressor with 10 to 100 percent capacity mod-ulation enables continuous variable unloading that delivers imme-diate and significant benefits. While results vary per application, operators can expect improvements in three major categories:

• Reduced compressor cycling — the average compressor cycling is reduced up to 50 percent, but some scenarios have seen cycle counts go from 900 starts per day to 12 starts across a four-day span. This increases equipment reliability by reducing contactor wear and tear due to the infrequent cycling. It also saves energy from reduced in-rush, start-up currents and persistent consumption from running at full capacity.

• Improved temperature control — digital modulation is capable of temperature control within +/- 1 °F, giving operators the assurance that they are minimizing food loss while maintaining the highest quality of perishable items.

• Tighter suction pressure control — operating suction pressure ranges are significantly reduced, moving from double-digit suction pressures (psig) to single-digit levels. In some systems, operators have experienced as much as 89 percent improve-ment in suction pressure.

These results make an open and shut case for a digital compressor upgrade. As awareness of this option becomes more well-known, many supermarket operators will opt for capacity modulation using this relatively simple upgrade to their existing rack systems.

Other Methods of Capacity Modulation

The challenge of modulating capacity in centralized rack refrigeration systems is not a new one, and system designers have made several attempts to solve the problem. Though none are as effective as digital capacity modulation, technicians still frequently encounter these systems:

• Uneven rack — one potential solution is to design an uneven rack made up of compressors of varying capacities. But

this still results in high cycling (on/off) rates and provides insufficient temperature control.

• Variable speed drives — known to provide effective capacity modulation, but is often considered cost-prohibitive technology.

One digital compressor per suction group can provide precise capacity modulation from 10 to 100 percent. The results are up to 50 percent reduction in compressor cycling, improved equipment reliability and precise temperature control.
