It’s been than more than two years since the Department of Energy (DOE)
announced its final rule on energy conservation standards for commercial
refrigeration equipment. At the time of its 2014 announcement, many industry
stakeholders expressed their objections to this standard, claiming that it was
founded on insufficient premises and nearly impossible to meet.
The industry’s most substantial objection resulted in a formal petition submitted
to federal court—one that consolidated the opinions of the American Heating and
Refrigeration Institute, some of its member companies and the North American
Association of Food Equipment Manufacturers. In August, the Appeals Court ruled
in the DOE’s favor, effectively quashing any hopes that the ruling would be amended
or delayed. Any lingering questions about the implementation of the DOE’s new
efficiency standard have been laid to rest.
Now, the compliance deadline is just six months away. All stand-alone
commercial refrigeration equipment released after March 27, 2017, will need to
achieve up to 30–50 percent reduction in energy consumption. Some OEMs have
already cleared this hurdle. But, if you are an OEM who thought this deadline
wouldn’t come to pass and have delayed research, design, development and testing
of new products, you are no doubt feeling a new sense of urgency. The regulatory
push has come to shove.
That’s why the “Countdown to Compliance” feature story in this issue is devoted
to addressing this imminent deadline — not only what it means to OEMs, but also
evaluating its larger impacts on the industry. In our Helix Highlight article, we’re also
introducing a new simulation model for ice machines that can help OEMs with rapid
prototyping and allow them to virtually test the efficiency impacts of system design
and component changes.
It’s important to remember that the March 2017 compliance date is just the first
in a series of regulatory milestones in the journey that lies ahead. We know there will
soon be changes in acceptable refrigerants, and we’re well aware of the subsequent
energy minimums to be enforced on other classes of commercial refrigeration
equipment. The next several years will be full of challenges. Each regulation will need
to be approached with specific technologies and strategies to achieve compliance.
Our commitment to helping our partners prepare for each step along the path
to compliance is stronger than ever. To Emerson, it’s about more than seeking fresh
approaches to system designs; it’s about helping the industry confidently embrace
a new era of refrigeration. Regardless of where your company may be on its journey
toward compliance, we have the resources and the willingness to help.

For the last several years, the refrigeration
industry has been forced to come
to terms with a dynamic and often
uncertain regulatory environment. On the
one hand, the DOE is mandating significant
new energy efficiency improvements. On the
other hand, the Environmental Protection
Agency (EPA) is phasing out the use of
widely used high global warming potential
(GWP) refrigerants while sanctioning a
growing list of acceptable substitutes via its
Significant New Alternatives Policy (SNAP)
program. The convergence of these two
regulatory fronts has created the perfect
storm — a once-in-a-generation occurrence
that promises to permanently reshape the
commercial refrigeration landscape.
This tectonic shift in our industry is
creating unprecedented challenges for
every segment of the commercial refriger-
ation supply chain, from OEMs, wholesalers
and contractors to design consultants
and end users.
Foodservice equipment manufacturers
find themselves at the leading edge of this
transition. March 27, 2017, is the DOE’s
energy reductions compliance date for
stand-alone commercial refrigeration
equipment — an average of 30–50 percent
reductions, as measured in kWh per day.
Affected equipment architectures include:
remote condensing commercial refrigerators
and freezers; self-contained commercial
refrigerators and freezers with and without
doors, as well as open display cases. This
means that all new equipment manufac-
tured after this date fall within the purview
of this rule. And with the EPA’s decision to
phase out commonly used refrigerants,
like R-404A and HFC-134a in 2019, OEMs
must factor this key design consideration
into their engineering equation.
What’s at stake for OEMs?
The combination of these fast-approaching
regulatory deadlines poses significant busi-
ness risks and challenges to foodservice
OEMs. Important considerations include:
One design cycle or two? — When it
comes to achieving DOE and EPA regu-
latory compliance, OEMs face a critical
design choice: approach each regulation as
a separate engineering effort or combine
compliance into a single design cycle.
Compressed design cycle — Regardless
of the design cycle decision, OEMs will need
to allot sufficient laboratory and testing time
to make the necessary design adjustments
to achieve DOE compliance and secure
requisite UL, ASHRAE and NSF certifications.
Civil penalties — The details around
how the DOE will enforce the ruling remain
to be seen, but past performance indicates
that they will be prepared to issue civil
penalties. After March 27, 2017, equipment
manufacturers who are still offering reach-in
units that don’t comply with the DOE rule
may be subject to these penalties.
Peer scrutiny — As many OEMs will be
making significant investments in design
changes to achieve compliance, those who
are neglecting or avoiding these efforts
will likely be subject to the scrutiny of their
industry peers. In other words, the industry
will also police itself.
Registration in DOE compliance
database — It’s important to understand
that the DOE maintains a database of com-
mercial equipment for compliance called
the Compliance Certification Management
System (CCMS). Please see: https://www.
regulations.doe.gov/ccms. This data-
base is essentially a record of the baseline
energy consumption of equipment prior
to making the mandated design changes
to achieve new energy efficiency levels.
Manufacturers who have not listed their
equipment in this database may be subject
to civil penalties.
Market pressures — Because design
consultants and end users are already
seeking refrigeration units that comply
with DOE and EPA regulations, OEMs who
Here are the key facts about the DOE and EPA final rules with respect to stand-alone, commercial refrigeration equipment.
DOE Energy Conservations Standards for Commercial Refrigeration Equipment
Effective date: May 27, 2014
Summary: The DOE is mandating a
30–50 percent reduction (on average)
in energy consumption on new
stand-alone commercial refrigeration
equipment, as measured in kWh per
day. Efficiency is evaluated on the
system as a whole, including: doors,
lighting, insulation, controls, fans
and the condensing unit.
Compliance date: March 27, 2017
EPA Change of Listing Status for Certain Substitutes Under the SNAP Program
Effective date: July 20, 2015
Summary: The EPA, through its SNAP
program, has changed the listing status
of many common refrigerants to
“unacceptable”. Among these “delisted”
refrigerants include R-404A, R-507A,
R-410A, R-407A/C/F and HFC-134a.
Compliance date: Jan. 1, 2019, in
medium-temperature (MT), stand-alone
equipment less than or equal to 2,200
BTU/hr. and not containing a flooded
evaporator. The same ruling states a
compliance date of Jan. 1, 2020, for MT
stand-alone equipment above 2,200
BTU/hr. with or without a flooded
evaporator, as well as low-temperature,
stand-alone units.
The EPA SNAP initiative continues to
propose additional “change of status”
notices as addendums to its 2015
ruling. This results in both the intro-
duction of acceptable, new refrigerant
substitutes and the delisting or phasing
down of other existing substances.
New, low-GWP refrigerant alternatives
will play an ever-increasing role in
commercial refrigeration.
See the chart below for an illustration
of how the timing of DOE and EPA
rulings interact.
Both DOE and EPA rulings take effect in the 2017–2020 time frame. But, the effective dates of respective rulings don’t necessarily correspond. To avoid a duplication of efforts, OEMs should attempt to satisfy both requirements in one product development cycle.

fail to bring viable products to market may
face significant business risks.
Broad impacts felt throughout the
supply chain
The impacts of this perfect regulatory storm
will be felt throughout the commercial refri-
geration supply chain. Whether you are a
wholesaler, contractor, manufacturing rep,
dealer, design consultant or end user, there are
many uncertainties and questions, including:
• Which products should I select or
recommend for specific applications?
• What servicing considerations should I
be aware of?
• Should I select DOE-compliant units now
and EPA-compliant units later, or seek
products that achieve compliance to
both regulations from the outset?
• Which compression and condensing unit
manufacturer offers the best efficiency for
commercial refrigeration equipment?
Because no two applications, business
requirements or scenarios are the same,
there is no single correct answer to these
questions. As OEMs begin to manufacture
refrigeration units that satisfy these more
stringent regulatory requirements, the
variety of options available in the market
will only increase. Selecting the best option
for you or your customers’ businesses will
require a more thorough understanding of
the technologies and refrigerants at play.
Don’t go it alone: consult an expert
Whether you’re a foodservice OEM or
another critical link in the commercial
refrigeration supply chain, there are difficult
decisions to be made, both now and in the
While foodservice OEMs of commercial
refrigeration equipment are the first segment
to feel the pressure of DOE regulations,
every segment will be impacted by conver-
gence of these regulatory actions. Here’s
what you can expect:
• OEMs: should presently be active in the
engineering design cycle to improve their
new stand-alone equipment, including
testing and certification
• Wholesalers: must be prepared for
changing inventories based on improved
condensing units and compressors
installed in new OEM systems
• Contractors: need to understand the
new technologies, refrigerants and
applications from an installation and
servicing perspective
• Design consultants: must be well-
versed in the regulatory impacts to
better advise end users in the selection
of energy-compliant and alternative
refrigerant systems
• End users: will need to reconcile these
two regulations and their timing to make
the best decisions for their future
coming years. Perhaps the most challenging
aspect of this transition is gaining the
level of understanding necessary to decide
what’s best for your business or your
customers. But this is not something to take
on single-handedly. Emerson is uniquely
qualified and prepared to answer your
questions and help you take the next steps.
If you’re an OEM who has hasn’t begun
to think about DOE compliance, we can help
guide you through this rapid transition. No
two systems are alike, and we understand
that achieving compliance is more than just
changing the engine under the hood. Rather,
it’s about evaluating the efficiency of the
whole system — from doors, lighting, fan
motors and insulation to smart controls and,
of course, the compressor and condenser coil.
Emerson can help you expedite the
testing process, limit costly lab time and save
your resources by utilizing the third party test
lab in our Design Services Network (DSN).
DSN offers the certifications and accredita-
tions to ensure your equipment is compliant,
including: UL, NSF and ASHRAE. Our DSN is
also accredited with ISO 17025 and approved
by the California Energy Commission.
Not only do we understand the real
challenges before you, we have also devel-
oped the strategies, expertise and breadth
of products to help you successfully make
this transition. For two years, we’ve been
developing a new lineup of compressors and
condensing units that address the challenges
posed by the DOE and EPA. Our next
generation product portfolio will introduce:
• Copeland Scroll™ line expansion to include
smaller displacements, horsepower and
capacities for both medium- and
low-temp applications
• Higher-efficiency fractional horsepower
reciprocating hermetic compressors
• Higher-efficiency condensing units
designed to deliver double-digit
efficiency gains
We’re prepared to help you achieve com-
pliance and determine the most viable path
forward for your business.
The first steps in a larger journey
While many consider the March 27, 2017,
DOE deadline on commercial refrigeration
equipment the first significant regulatory
milestone, it’s important to remember
that it’s one of the first steps the industry
must take on this journey for compliance.
Among the challenges that still lie on the
path ahead include:
• Jan. 1, 2018: DOE new efficiency targets
on automatic commercial ice makers
• Jan. 1, 2018: EPA delisting R-404A for
remote condensing unit architectures
• Jan. 1. 2019: EPA begins phasing out
R-404A, R-507A, R-410A, R-407A/C/F and
HFC-134a in stand-alone units
• Jan. 1. 2020: DOE new efficiency targets
for walk-in coolers and freezers
There are many miles ahead of us in
this journey, and for many in the industry
this is uncharted territory. Emerson is com-
mitted to effectively navigating this shifting
regulatory landscape and helping guide
the industry toward the next generation of
refrigeration technologies and equipment
architectures. Through continued collabora-
tion and innovation, we’ll work with you to
create systems that are both economically
and environmentally viable.
We understand that achieving compliance is more than just changing the engine under the hood. Rather, it’s about evaluating the efficiency of the whole system — from doors, lighting, fan motors and insulation to smart controls and, of course, the compressor and condenser coil.
How will this transition impact you?

8 E360 Outlook Volume 3 Number 1
Food Bank Pays It Forward and Nets
Refrigeration PaybackDigital refrigeration upgrade leads to utility rebate
and increased reliability
SU C C E SS S TO RY
As an affiliate of Feeding America, the West Ohio Food
Bank serves 170 food pantries, soup kitchens and
shelters throughout 11 counties in western Ohio. The
non-profit organization stores both purchased and donated
items in its 35,000 square-foot facility, including a wide vari-
ety of nutritious frozen and refrigerated offerings in its 5,000
square-foot freezer and 2,500 square-foot refrigerator. In
recent years, the refrigeration equipment supporting these cold
storage units was becoming failure-prone, resulting in excessive
maintenance costs and unwanted headaches to the West Ohio
Food Bank’s operators.
So, when representatives from Emerson approached the
non-profit about donating all-new equipment and components
for a digital refrigeration system, operators were intrigued. When
they found out that the system could significantly reduce their
energy footprint, greatly improve refrigeration reliability and
significantly lower maintenance costs, they were all ears. And, when
Emerson secured a $2,500 rebate from the utility, AEP Energy,
based on analysis of projected efficiency gains, operators officially
gave Emerson the green light to begin the project in late 2014.
In with the new, low-condensing operation
The West Ohio Food Bank had inherited their refrigeration system
from the facility’s previous tenant, a supermarket warehouse.
Like many traditional, fixed-capacity compressor and mechanical
component systems, theirs was characterized by a high rate of
compressor cycling (on/off) to match the required refrigeration
capacity. The legacy system had become a source of excessive
downtime and repair costs for food bank operators, requiring
the purchase of replacement fixed-capacity compressors to
keep the system running and resulting in as much as $20,000
in operating expenses.
For Emerson, the project presented an opportunity to
demonstrate a proof-of-concept that utilized their Copeland
Discus™ Digital compressor for precise capacity modulation
and the components needed to enable low-condensing
operation. Although low condensing is not necessarily a new
concept, improvements in controls technology and a reduction
in costs are making it a more valid option for many operators
seeking to reduce energy consumption while improving
refrigeration reliability.
Low-condensing systems allow the head pressure to float
from 10–20 °F above the ambient temperature down to 60 °F,
as opposed to fixed-capacity systems that are designed for
105 °F conditions, regardless of the actual ambient temperatures.
Floating the head pressure allows compressor capacity and
energy efficiency to increase as the ambient temperature
drops, delivering up to 15–20 percent energy efficiency ratio
improvements for every 10 °F decrease in head pressure.
Emerson approached
West Ohio Food Bank about donating
all-new equipment and components
for a digital refrigeration system.
The system would significantly reduce their
energy footprint, greatly improve
refrigeration reliability and significantly
lower maintenance costs.
Meeting the food bank’s cold storage requirements had become increasingly difficult for the facility’s legacy, fixed-capacity
refrigeration system.

Like money in the “food” bank
Once the installation was complete, AEP Energy monitored the
facility’s power output to verify that the actual system perfor-
mance met the efficiency criteria on which the rebate was given.
Not only was the system performing as expected, it rectified
the problems that the West Ohio Food Bank operators had been
grappling with since taking ownership of the facility. Following
is a brief summary of the new system benefits:
• Maintenance — the system has not required maintenance
since being installed. The low rate of compressor cycling
increases system reliability and compressor/system longevity,
and provides much improved energy efficiencies.
• Efficiency — low-condensing operation and precise digital
modulation result in significant improvements to energy
efficiency, as the system now is capable of adjusting to the
changes in the seasons and ambient temperatures.
• Performance — in addition to eliminating downtime, the new
digital upgrade delivers improved temperature control within
1 °F. Suction pressure control is also significantly tighter —
as much as 89 percent improvement in some cases.
Emerson donated the following system components
to West Ohio Food Bank for a significant upgrade
to the facility’s refrigeration equipment. All but the
VFD fan were Emerson components.
• One Copeland Discus Digital compressor replaced the
previous fixed-capacity compressors. Not only does
this allow the system to modulate and precisely adjust
its capacity, it also eliminates the problem of
compressor cycling.
• Two EX Series electronic expansion valves (EEV) enable tight
control of the floating head pressure process, making it
possible to lower the system’s condensing temperatures
with the ambient temperatures.
• Two electronic controllers serve as the drivers for the
EX Series valve.
• Variable frequency drive (VFD) fan provides the method
through which the system reduces condensing temperatures
without cycling.
Emerson secured a $2,500 rebate
from the utility, AEP Energy, based on
analysis of projected efficiency gains.
Once the installation was complete,
AEP Energy monitored the facility’s
power output, verifying that
the actual system performance
met the efficiency criteria on which
the rebate was given.

Refrigerant leaks are a persistent concern in the commercial
refrigeration industry, and forward-thinking grocers
are seeking ways to limit leaks, reduce their negative
environmental impacts, and avoid the potential for significant
Environmental Protection Agency (EPA) fines. For one prominent
U.S. supermarket chain, these efforts have even become formalized
in a leak detection program that serves as a key component in
their corporate sustainability objectives.
With all the attention that’s been brought to the leak
detection issue in recent years — via the EPA’s proposed update
to Section 608 and the handful of high-profile cases where fines
have been handed down for violations — this particular retailer
was ahead of the curve. Having already reduced refrigerant leaks
to well below industry averages, they also participated in an
Emerson Retail Solutions remote leak detection pilot program
that promised to identify small leaks early. The program not only
enabled the grocer to fix problems faster, it often prevented the
occurrence of catastrophic failures from major leaks.
Because fluctuations in refrigerant levels are a normal part
of the refrigeration cycle, detecting refrigerant leaks across the
complete system is notoriously difficult. Low refrigerant levels
have many damaging consequences on refrigeration system
performance, including:
• Excess compressor wear and tear
• Reduced compressor and system capacities
• Premature system failures
• Double-digit efficiency losses
Left undetected, a slow refrigerant leak can turn into a
catastrophic failure that has far-reaching operational and business
implications, including: food loss, food quality, reputation damage
and equipment replacement costs — and the cost of the lost
refrigerant, which can be quite substantial on its own. These are
all scenarios the retailer wanted to avoid.
Detecting deviations in refrigerant levels
Emerson’s remote slow leak detection program is based on
harnessing the power of machine learning technologies to
continuously monitor system refrigerant levels and notifying
stakeholders when there is a deviation in these levels compared to
established models. Unlike “sniffing” leak detection systems,
which can only monitor parts of the refrigeration systems typically

It’s no surprise that many of the trends driving
the HVAC industry are geared toward providing
solutions that deliver the most energy-efficient
components, systems and buildings. During our
recent E360 Webinar, we explored the key aspects
shaping the commercial HVAC industry due to the
Department of Energy’s (DOE) new energy efficiency
minimums and the Environmental Protection
Agency’s (EPA) phase-down initiative:
• DOE adoption of the IEER portion of ASHRAE
90.1-2013 energy efficiency standard for
commercial AC packaged and split systems,
effective nationally on 1/1/2018
• Technology options available to optimize
integrated energy efficiency ratios for part load
system efficiency
• Changing refrigerant landscape for AC and heat
pump applications, including: EPA delisting
and phase-down of HFCs, the introduction of
low-global warming refrigerant alternatives and
the implications to system designs

Meeting Future Refrigeration Energy Regulations With Today’s Technology Alternatives March 17, 2015
located in closed areas, remote leak detection monitors the complete refrigeration system by analyzing key refrigeration operating indicators to provide actionable intelligence.
To capture key performance data in the retailer’s network of 100 retail stores, Emerson utilized an existing refrigeration management controller at each location. Key data points measured to evaluate refrigerant levels included:
• Ambient temperatures
• Discharge pressures
Using this time-based data to analyze equipment performance, smart fault detection algorithms in Emerson’s remote leak detection system established models that depicted normal liquid refrigerant levels in various operating conditions. Data and refrig-erant level models were then consolidated and processed through Emerson’s ProAct™ Services using cloud-based data analysis.
When the system detected a deviation in refrigerant level from an expected level for the given operating conditions, it generated an advisory notification reporting on the anomaly. Depending on the degree of deviation, the system issued a warning or alarm to Emerson’s ProAct Service center. There, a team of experienced refrigeration experts remotely performed triage to prioritize the advisory. Then, the system notified the appropriate parties in the retailer’s stores, providing additional information on the equip-ment, its operating condition, location and potential resolution steps. Critical situations that required immediate attention were routed directly to the chain’s contractor crews to perform on-site validation and necessary repairs.
Pilot program results
After one year of participating in the Emerson remote leak detection program, the supermarket chain had reduced its refrigerant leaks by 25 percent, dropping its overall refrigeration leak rate to less than half of the industry average.
With each store’s refrigeration system averaging approximately 2,000 pounds of refrigerant charge, this 25 percent reduction in leaks equated to $560 savings annually in reclaimed refrigerant per store, totaling $56,000 annually for the 100-store network included in the pilot. Overall, the chain calculated it would achieve payback on its investment in significantly less than 24 months — the financial benchmark established for the program’s success.
An unexpected benefit of Emerson’s leak detection program was the discovery that the chain’s existing refrigerant levels were marginally low, causing refrigeration units to work harder and longer, creating unnecessary wear and tear and consuming more energy. By adjusting refrigerants to optimum levels, the retailer was able to improve overall refrigeration performance, better manage safe food temperatures, and likely achieve marginal reductions in energy consumption.
Upon completion of Emerson’s remote leak detection pilot,
the supermarket chain was convinced of the program’s operational, financial and sustainability benefits. The retailer elected to expand the service beyond its network of 100 stores.
Remote leak detection can identify small leaks much earlier than other methods, sometimes as much as 30 days sooner than “sniffing” technologies. That’s important because every additional day of refrigerant leakage contributes to negative environmental impacts, higher risk of large repair costs, potential food safety issues and food loss, and shopper dissatisfaction. Consider the following scenario based on the EPA’s GreenChill1 research of industry averages:
• The average supermarket loses 25 percent of its annual refrigerant charge to leaks.
• With an average refrigerant charge of 3,500 pounds, this leakage equates to 875 pounds of lost refrigerant per year.
• At the cost of approximately $7 per pound of refrigerant, one supermarket stands to lose $6,125 annually to refrigerant leaks.
• If this supermarket is one of 100 stores in a larger network, the chain could potentially lose more than $600,000 annually.
• Using R-404A as the refrigerant, the carbon dioxide equivalent (CO2eq) of this leak level is 3,431,400 pounds annually per store.

While we’ve all been justifiably
focused on understanding
system design changes to
reduce energy consumption and new
refrigerants to lower our carbon footprint,
no one in our industry has stepped forward
to lead the charge on solving the technician
shortage in a holistic manner.
In an era of widely varying system
architectures, changing technologies, and
reliance on emerging and natural refrig-
erants, the need for qualified technicians
is greater than ever. At Emerson’s annual
contractor roundtable, the lack of qualified
technicians was cited as the number one
challenge facing contracting business
owners. I would argue that it is perhaps our
industry’s most pressing issue.
We wrote about the severity of the
technician shortage in a recent E360
Outlook article entitled, “Bridging the
Refrigeration Gap,” where we began to
outline steps the industry can take to start
addressing the challenge. This process will
require not only the participation of industry
stakeholders — including contractors,
manufacturers, end users, wholesalers and
trade associations — but also the perspec-
tives of educators, outside industries and
government agencies.
There is no quick fix to this situation.
Finding a solution will take months, if not
years, and require the commitment of
a dedicated organization to drive this
effort forward. Through our E360 platform,
Emerson is committing to lead this
important initiative.
First steps at E360 Forum
At our E360 Forum in Tucson, Ariz., we
took our first steps toward defining the
framework of this effort. The event
assembled industry stakeholders and
vocational school educators for a half-day,
E360 Industry Challenge session to examine
the current state of the HVACR technician
profession. Areas of focus included:
• Awareness — Do we understand what’s
at stake and agree on the problem?
• Recruitment — How can we attract
individuals with aptitude?
• Training — How can these individuals
receive training, and what should those
programs look like?
• Certification — Which types of certification
should be made available?
• Retention — How can we keep individuals
engaged throughout their careers?
The group then broke into teams
for ideation sessions, and each team was
tasked with focusing on a specific objective.
Results were then reported back to the
group and documented as a baseline to
help set the stage for the next step.
The next step — Forming a larger coalition in 2017
In 2017, E360 will host a larger Forum
focused solely on addressing the technician
shortage. This multi-day event will feature
an interdisciplinary team dedicated to un-
derstanding the problem, defining a working
road map for meeting the challenge, and
assigning specific actions to solve it.
In addition to industry stakeholders, we
will seek insights from previously untapped
resources. Other industries have already
solved similar problems; learning from those
lessons will be extremely valuable.
We will also seek the expertise of
educators who have experience in developing
curriculum and recruiting candidates. Our
technical colleges, vocational schools and
trade associations will all play key roles in
shaping this piece of the puzzle. We may also
benefit from government representatives
and/or agencies who may be able to affect
policy changes that can further our cause.
This larger event will pick up where we
left off in Tucson, and assign small group
breakout sessions to focus on specific
objectives. As team results are shared with
the large group, attendees will take on specific
action items which can then be used as metrics
for progress in future follow-up meetings.
Certainly, the current regulatory climate
is a dynamic situation that will continue to
impact us for years to come, and our E360
platform will remain dedicated to helping you
navigate this changing landscape. But with-
out qualified technicians to service the next
generation of refrigeration equipment, our
industry will have an even bigger challenge.
I believe that together we can solve the
technician shortage. If you want to contribute
to this effort or have ideas that may help,
please reach out to us at E360. Stay tuned
for updates on this topic.

System simulation models have been
widely used for decades to help
commercial refrigeration equipment
manufacturers test the impacts of various
components and design options. By
simulating the steady-state operation of
the vapor-compression cycle, these models
have served as the basis of predictive
evaluation in many modern refrigeration
applications. Engineers rely on these virtual
models to expedite the design process
and test prototypes before proceeding
with physical equipment development.
This has not been the case with ice
machine simulation models … until now.
The transient nature of ice machine
operation — continually cycling between
ice formation and harvest modes — presents
challenges in simulating the effects on
the system during these transitions.
That’s why developing a usable simulation
model for the evaluation of ice machines
has been historically problematic. It’s also
why our engineering team at The Helix
Innovation Center decided it was time to
tackle this challenge head-on.
At the International Refrigeration and
Air Conditioning Conference, held in July
at Purdue University, a team of Emerson
engineers presented a concept for the
“Simulation of an Automatic Commercial
Ice Maker.” This transient simulation model
will enable the prediction of component
conditions and loads under different
operating environments, thus allowing
engineers to assess the effects of system
design and component changes.
The DOE’s new standard of efficiency
The release of this simulation model has
timely implications for automatic commercial
ice maker (ACIM) manufacturers. In 2015,
the Department of Energy (DOE) revised
its efficiency standards for machines that
produce 50–4,000 pounds of ice per day.
The ruling will take effect on Jan. 1, 2018,
requiring ACIMs manufactured after that
date in the United States to reduce energy
consumption by 10–15 percent.
Since ACIMs are produced in a wide
range of capacities and used in restaurants,
hotels, convenience stores and hospitals,
compliance to the new standard has
broad industry implications. The ruling
affects the two primary classes of ACIMs:
batch ice machines (aka “cubers”); and
continuous ice machines (aka “flakers”
and “nuggets”).
With the new DOE standard taking
effect in a little more than a year, many ACIM
manufacturers have either already begun
or are planning to kick off the engineering
design cycle. Our new ACIM simulation
model is available to help our customers
meet this fast-approaching deadline.
ACIM simulation model details
A typical ACIM “cuber” consists of two
major subsystems: the vapor compression
Simulation Model Breaks the Ice on Meeting Efficiency Targets
H E L I X H I G H L I G H T refrigeration system; and the water
supply, circulation and purge system.
Refrigeration system components include:
compressor, air-cooled condenser, thermo-
static expansion device, liquid line/suction
line interchanger, and an evaporator that
consists of copper tubing attached to a
copper or stainless steel grid that serves as
the ice-making surface. Once a sufficient
amount of ice is formed on this grid, a
hot-gas solenoid valve switches to direct
the refrigerant from the compressor to the
evaporator, thereby releasing the ice into
a storage bin.
The water side of the system consists
of a water sump, circulation pump, plastic
tubing and an evaporator water distributor.
A water supply connection control valve
and a purge drain control the flow of water
in and out of the ice maker. Please see the
illustration for a schematic of a batch cuber
type of ice machine.
In the ACIM model, the transient
ice machine operation incorporates a
combination of algebraic and time-based
differential equations for the main system
components. Its specific operating
parameters are the ambient air temperature
and the incoming water temperature.
The model is designed to simulate the
transient operation of an ACIM cuber
based on fundamental principles and
generalized correlations — calculating
time-varying changes in system properties
and aggregating performance results
as a function of machine capacity and
environmental conditions.
Rapid prototyping
The ACIM simulation model will enable
engineers to perform rapid “what if”
analyses, allowing them to quickly evaluate
the impact of a variety of system design
options, including:
• The size of the air-cooled condenser and
finned surfaces
• Changes in air/water flow rates, as well as
ambient air and inlet water temperature
• Compressor capacity and/or efficiency
during freeze and harvest cycles
• Evaluation of alternative refrigerants
• Suction/liquid line heat exchanger
• Thermal expansion valve properties
To verify the validity of simulation data,
results from the model were compared
with the experimental data of a standard
500-pound capacity ice machine, operating
under various ambient air and water inlet
temperatures. Key measures of the ice
machine’s performance include: cycle time
(duration of freeze and harvest cycles);
energy input per 100 pounds of ice; and
energy usage during a 24-hour period.
Against these measures and in a variety of
operating conditions, the model achieved
accuracy levels within 5 percent.
Now that it’s established, the ACIM
simulation model enables the prediction of
component performance, evaluation of loads
under different operating conditions and
assessment of system design changes — all
within a virtual environment. We’re looking
forward to working with our ACIM OEM
partners to help them achieve the efficiency
levels set forth by the DOE.

Compressor failure is a worst-case scenario in commercial refrigeration applications. For supermarket operators, it can mean catastrophic product losses compounded by
the expenses of system maintenance, repairs and compressor replacement. For the service technician whose responsibility is to properly diagnose and prevent system faults before they occur, system failures can blemish their reputation.
In a perfect world, retailers would keep a dedicated service technician on-site to continuously monitor refrigeration system performance. But in reality, this scenario is just not feasible. That’s why the advent of built-in compressor electronics — like Emerson’s CoreSense technology — is revolutionizing the commercial refrigeration service paradigm. CoreSense technology provides continuous system monitoring, placing protection and diagnostics at the contractor’s fingertips.
In the span of a few short years, the prevalence of on-board compressor electronics has grown dramatically. CoreSense technology, for example, is available on both Copeland Scroll™ and Copeland Discus™ compressor lines, in part to enable more advanced energy-efficient refrigeration techniques such as digital capacity modulation and liquid injection control. As contractors more frequently encounter these units in the field, the challenge is to not only embrace their obvious benefits, but to exploit their capabilities to their maximum potential.
Communications-enabled connectivity
Designed with advanced communication capabilities, CoreSense technology allows contractors to accurately diagnose and troubleshoot system issues — either at the customer’s site or remotely via mobile device access.
• PC interface kit — once at the customer’s site, contractors can connect their laptop to the CoreSense module via a USB to RS485 cable. Software then gives the contractor visibility to real-time system data and historical performance to help them quickly analyze and troubleshoot system issues. Contractors also have the option to leave a laptop connected to the controller to generate and capture data logs based on user-defined system performance criteria.
• Remote access — for maximum contractor benefit, CoreSense technology can be paired with a facility management or site supervisory system controller to extend its data to remote technicians in the field, a monitoring
service, or a service department headquarters. This gives contractors access to complete system performance data from their mobile device or laptop, allowing them to monitor all stores in their service area and receive alerts when there is a system fault at any of their connected locations. With remote access, historic system data can be quickly accessed to analyze and troubleshoot errors.
CO N T R AC TO R CO N N EC T I O N
CoreSense™ Technology Gives Contractors a Sixth Sense
Failure protection
One of the most obvious benefits of CoreSense technology is its ability to protect the compressor from damage, primarily through its system trip or reset functions, including:
• Incorrect phase rotation protection (Copeland Scroll only)
• Discharge temperature protection (optional on Copeland Discus)
• Oil pressure protection (Copeland Discus)
In the event of a lockout condition that warrants compressor shutdown, CoreSense technology will stop the compressor until the event has been cleared by the contractor (either remotely or on-site). Fault alarm codes tell the contractor the source of the issue so they can begin trouble-shooting. This not only saves retailers the cost of replacing a compressor, it saves contractors time by providing advanced diagnostics through troubleshooting “apps” to determine the root cause of the problem in preparation for repairs.
Advanced diagnostics
CoreSense technology gives contractors a wealth of historical system data that they can use, both for troubleshooting current issues or preventing system failures before they happen. Following is a partial list of faults and key performance indicators available:
• Over current protection
• Over/under voltage protection
• Unbalanced load detection
• Liquid injection
• Anti-short cycle time delay
• Digital fault code display/remote alarming
• Locked rotor protection
• Motor overheat protection (Copeland Discus)
• Welded contactor protection (Copeland Scroll)
On-board compressor diagnostics make good sense
While the emergence of compressor electronics may present a learning curve for some contractors, there’s no ques-tioning their benefits. Technicians can leverage the wealth of information available at the compressor to evaluate the entire refrigeration system. Not only does CoreSense technology allow contractors to analyze and perform key actions remotely, it also gives them the tools to quickly and accurately diagnose system issues and conduct more productive service calls. As the technology continues to evolve, contractors can expect the expanding integration of compressor electronics with even more diagnosis and protection capabilities, along with continued improve-ment to apps and the ability to access information.
By using the compressor as a sensor for refrigeration system failure, CoreSense technology has proved invaluable in the field. In addition to giving contractors access to data that allows them to limit nuisance service calls, CoreSense technology also helps them detect system faults before they lead to bigger problems, often preventing expensive food loss and compressor failure. Here are a few real-world examples that demonstrate its advantages.
Contactor failure — when CoreSense technology detected a voltage imbalance in the compressor of a supermarket refrigeration system, it triggered the shutdown of the compressor. Weeks later, it shut down the compressor and reset it again after sensing a missing phase and no three-phase faults. On closer inspection of the three recent errors, the technician identified and replaced a faulty contactor. Without CoreSense technology, the compressor would have continued cycling and led to a single-phase motor burn. The supermarket avoided a compressor failure and saved approximately $6,000.
Low pressure cut out failure — the compressor used in a conve-nience store’s walk-in cooler was experiencing low refrigerant pressure, and the low pressure cut-off switch had failed. This caused the system to continue to run in a vacuum with the suction pressure below its setpoint. As the compressor began to overheat, the internal motor protection system prevented compressor failure. CoreSense technology sent system trip alarms to the contractor, who then responded to quickly diagnose and repair the pressure switch issue. The store avoided having to replace the compressor while maintaining a cooler temperature.
Frozen defrost timer — the freezing over of a defrost timer at a butcher shop had prevented the compressor from running, even while the thermostat called for cooling. This triggered CoreSense technology to send a system trip warning to the store owner. Four hours later when the situation persisted, the system generated and sent an open circuit alarm to the store owner, indicating no power at the compressor. The store’s technician arrived shortly thereafter to remedy the issue with the timer and reset the scroll compressor. While the defrost timer was not part of the compressor itself, the diagnostics technology prevented product loss, estimated to be approximately $10,000.

The factors driving the selection of commercial
refrigeration equipment in convenience stores and
restaurants have changed drastically in recent years.
While reliable refrigeration is still a top priority, the days of
“just keep it cold” have given way to a much broader range of
operator challenges and concerns, including:
• Offsetting rising energy costs with new energy
efficiency targets
• Reducing energy consumption to meet minimum
efficiency levels
• Creating optimal in- and outside-store environments
for customers and neighbors
• Identifying the potential for equipment failure in advance
to prevent costly product loss
• Evaluating the critical role of refrigeration system architecture
in total store energy usage
Enter the Copeland Scroll ™ Outdoor Refrigeration Unit,
X-Line Series, purpose-built for medium- and low-temperature,
walk-in coolers, freezers and display cases commonly found in
c-stores and restaurants. Utilizing scroll compressor technology,
variable speed fan motor control, large capacity condenser
coils, enhanced vapor injection (in low-temperature models
only) and advanced electronic controls, the X-Line meets
today’s challenging small-format refrigeration requirements.
Redefining Refrigeration
P RO D U C T SP OT L I G H T : O U T D O O R R E F R I G E R AT I O N U N I T
Built for maximum convenience, performance and protection
Much-improved Energy Efficiencies
With proven Copeland Scroll compressor technology, large condenser coils and smart
controls, X-Line units typically provide annual efficiency improvements of 20 percent or
more compared to legacy equipment and technology. Additional efficiencies are gained
when the outdoor units are used in place of traditional self-contained or other indoor
systems by removing the additional heat load from the building’s air conditioning system.
Superior Reliability and Protection Through Advanced Diagnostics
Built-in CoreSense™ diagnostics and protection allow operators to stop worrying about
product loss from equipment downtime. Errors can be quickly communicated to ser-
vice technicians and the system can take action to protect against many system faults
that could otherwise cause a compressor failure. The end results are improved reliability,
extended compressor lifespan and greatly reduced lifecycle costs.
Installation Flexibility From Slim Chassis
The X-Line’s slim profile, lightweight design and wall-mount option give operators
the flexibility to install the unit in the most space-constrained locations. In fact,
the X-Line is so unobtrusive it’s often mistaken for an AC split unit. This flexibility
lowers installation costs and helps avoid expensive system design workarounds or
relocation issues.
Ultra-quiet Operation From Strategic Noise Abatement Design
Operators located near residential areas or noise-restricted zones can take heart in having
the quietest standard unit available on the market today. At only 55 to 59 decibels,
the units produce less sound than a normal conversation. In most applications, unit
noise is virtually undetectable. The units are unobtrusive and allow more mounting
options where the sound produced by traditional units would prevent their use, such
as customer-facing locations near entryways, patios or even indoors.
Corrosion-resistant and Designed for Extreme Conditions
The X-Line is designed to withstand harsh and extreme environments, from arctic
blasts to desert heats. Protective enclosure and condenser coil fin coatings resist
corrosion in coastal zones. A heated and insulated receiver allows the unit to
operate in ambient temperatures as low as -40 °F. CoreSense electronic controls
constantly tune and adapt the system for optimum performance and efficiencies
in any condition.
Compliance With Regulatory Requirements
X-line models are tested to exceed the Department of Energy’s new requirements
for Annual Walk-In Energy Efficiency Factor (AWEF) ratings for walk-in refrigerators.
With a horsepower range from 1.5 to 6, the X-Line is also designed for compatibility
with R-404A and many of the refrigerants the EPA has named as acceptable substitutes,
including: R-407 C/A, R-448A and R-449A. As acceptable refrigerants such as R-513A
and R-450A continue to be introduced as substitutes, the X-Line will incorporate this
growing list of alternatives. This makes X-Line units ideal for new equipment and
service replacement applications.
