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?

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

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.
