Energy Conservation Program: Test Procedures for Certain
Commercial and Industrial Equipment; Early Assessment Review:
Refrigerated Bottled or Canned Beverage Vending Machines
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Request for information.
-----------------------------------------------------------------------
SUMMARY: The U.S. Department of Energy (``DOE'' or ``the Department'')
is undertaking an early assessment review to determine whether
amendments are warranted for the test procedure for refrigerated
bottled or canned beverage vending machines (``BVMs''). DOE has
identified certain issues associated with the currently applicable test
procedure on which DOE is interested in receiving comment. The issues
outlined in this document mainly concern updates to industry standards,
test setup and conditions, product rating temperature, energy
consumption calculations, operating modes, alternate refrigerants, and
connected functions. DOE welcomes written comments from the public on
any subject within the scope of this document, including topics not
raised in this request for information (``RFI'').
DATES: Written comments and information are requested and will be
accepted on or before June 18, 2021.
ADDRESSES: Interested persons are encouraged to submit comments using

I. Introduction
DOE established an early assessment review process to conduct a
more focused analysis that would allow DOE to determine, based on
statutory criteria, whether an amended test procedure is warranted.
Title 10 of the Code of Federal Regulations (``CFR'') part 430 subpart
C appendix A section 8(a). This RFI requests information and data
regarding whether an amended test procedure would more accurately and
fully comply with the requirement that the test procedure produce
results that measure energy use during a representative average use
cycle for the product, and not be unduly burdensome to conduct. To
inform interested parties and to facilitate this process, DOE has
identified several issues associated with the currently applicable test
procedures on which DOE is interested in receiving
[[Page 27055]]
comment. Based on the information received in response to the early
assessment RFI and DOE's own analysis, DOE will determine whether to
proceed with a rulemaking for an amended test procedure.
If DOE makes an initial determination that an amended test
procedure would more accurately or fully comply with statutory
requirements, or DOE's analysis is inconclusive, DOE would undertake a
rulemaking to issue an amended test procedure. If DOE makes an initial
determination based upon available evidence that an amended test
procedure would not meet the applicable statutory criteria, DOE would
engage in notice and comment rulemaking before issuing a final
determination that an amended test procedure is not warranted.
A. Authority
The Energy Policy and Conservation Act, as amended (``EPCA''),\1\
among other things, authorizes DOE to regulate the energy efficiency of
a number of consumer products and certain industrial equipment. (42
U.S.C. 6291-6317) Title III, Part B \2\ of EPCA established the Energy
Conservation Program for Consumer Products Other Than Automobiles.
These products include BVMs, the subject of this document. (42 U.S.C.
6295(v)) \3\
---------------------------------------------------------------------------
\1\ All references to EPCA in this document refer to the statute
as amended through the Energy Act of 2020, Public Law 116-260 (Dec.
27, 2020).
\2\ For editorial reasons, upon codification in the U.S. Code,
Part B was redesignated Part A.
\3\ Because Congress included BVMs in Part A of Title III of
EPCA, the consumer product provisions of Part A (rather than the
industrial equipment provisions of Part A-1) apply to BVMs. DOE
placed the regulatory requirements specific to BVMs in 10 CFR part
431, ``Energy Efficiency Program for Certain Commercial and
Industrial Equipment'' as a matter of administrative convenience
based on their type and will refer to BVMs as ``equipment''
throughout this document because of their placement in 10 CFR part
431. Despite the placement of BVMs in 10 CFR part 431, the relevant
provisions of Title A of EPCA and 10 CFR part 430, which are
applicable to all product types specified in Title A of EPCA, are
applicable to BVMs. See 74 FR 44914, 44917 (Aug. 31, 2009) and 80 FR
45758, 45759 (Jul. 31, 2015). The regulatory provisions of 10 CFR
430.33 and 430.34 and subparts D and E of 10 CFR part 430 are
applicable to BVMs. Because the procedures in Parts 430 and 431 for
petitioning DOE for obtaining a test procedure waiver are
substantively the same (79 FR 26591, 26601 (May 9, 2014)), the
regulations for applying for a test procedure waiver for BVMs are
those found at 10 CFR 431.401 rather than those found at 430.27.
---------------------------------------------------------------------------
Under EPCA, DOE's energy conservation program consists essentially
of four parts: (1) Testing, (2) labeling, (3) Federal energy
conservation standards, and (4) certification and enforcement
procedures. Relevant provisions of EPCA include definitions (42 U.S.C.
6291), test procedures (42 U.S.C. 6293), labeling provisions (42 U.S.C.
6294), energy conservation standards (42 U.S.C. 6295), and the
authority to require information and reports from manufacturers (42
U.S.C. 6296).
Federal energy efficiency requirements for covered products
established under EPCA generally supersede State laws and regulations
concerning energy conservation testing, labeling, and standards. (42
U.S.C. 6297(a)-(c)) DOE may, however, grant waivers of Federal
preemption in limited instances for particular State laws or
regulations, in accordance with the procedures and other provisions set
forth under 42 U.S.C. 6297(d).
Federal testing requirements consist of test procedures that
manufacturers of covered products must use as the basis for: (1)
Certifying to DOE that their equipment complies with the applicable
energy conservation standards adopted pursuant to EPCA (42 U.S.C.
6295(s)), and (2) making representations about the efficiency of that
equipment (42 U.S.C. 6293(c)). Similarly, DOE must use these test
procedures to determine whether the product complies with relevant
standards promulgated under EPCA. (42 U.S.C. 6295(s))
Under 42 U.S.C. 6293, EPCA sets forth the criteria and procedures
DOE must follow when prescribing or amending test procedures for
covered products. EPCA requires that any test procedures prescribed or
amended under this section be reasonably designed to produce test
results which measure energy efficiency, energy use or estimated annual
operating cost of a covered product during a representative average use
cycle or period of use and not be unduly burdensome to conduct. (42
U.S.C. 6293(b)(3))
If DOE determines that a test procedure amendment is warranted, it
must publish proposed test procedures and offer the public an
opportunity to present oral and written comments on them. (42 U.S.C.
6293(b)(2))
In addition, EPCA requires that DOE amend its test procedures for
all covered products to integrate measures of standby mode and off mode
energy consumption into the overall energy efficiency, energy
consumption, or other energy descriptor, taking into consideration the
most current versions of Standards 62301 and 62087 of the International
Electrotechnical Commission (``IEC''), unless the current test
procedure already incorporates the standby mode and off mode energy
consumption, or if such integration is technically infeasible. (42
U.S.C. 6295(gg)(2)(A)) If an integrated test procedure is technically
infeasible, DOE must prescribe separate standby mode and off mode
energy use test procedures for the covered product, if a separate test
is technically feasible. (Id.)
EPCA also requires that, at least once every 7 years, DOE evaluate
test procedures for each type of covered product, including BVMs, to
determine whether amended test procedures would more accurately or
fully comply with the requirements for the test procedures to not be
unduly burdensome to conduct and be reasonably designed to produce test
results that reflect energy efficiency, energy use, and estimated
operating costs during a representative average use cycle. (42 U.S.C.
6293(b)(1)(A)) If DOE determines, on its own behalf or in response to a
petition by any interested person, that a test procedure should be
prescribed or amended, DOE shall promptly publish in the Federal
Register proposed test procedures and afford interested persons an
opportunity to present oral and written data, views, and arguments with
respect to such procedures. The comment period on a proposed rule to
amend a test procedure shall be at least 60 days and may not exceed 270
days. In prescribing or amending a test procedure, DOE shall take into
account such information as DOE determines relevant to such procedure,
including technological developments relating to energy use or energy
efficiency of the type (or class) of covered product involved. (42
U.S.C. 6293(b)(2)) If DOE determines that test procedure revisions are
not appropriate, DOE must publish its determination not to amend the
test procedures. DOE is publishing this RFI to collect data and
information to inform its decision to satisfy the 7-year-lookback
review requirement.
B. Rulemaking History
On July 31, 2015, DOE published a test procedure final rule (the
``July 2015 Final Rule'') that referenced updated industry test
methods, improved clarity of the procedure, accounted for new equipment
features, and reorganized the test procedure in 10 CFR part 431,
subpart Q, appendix A (``Appendix A'') and 10 CFR part 431, subpart Q,
Appendix B (``Appendix B''). The test procedure at Appendix B accounts
for additional BVM operating modes and is mandatory for demonstrating
compliance with the energy conservation standards in 10 CFR 431.296(b),
which are required for BVMs manufactured on or after January 8, 2019.
80 FR 45758; See also 81 FR 1028 (January 8, 2016). The specific
amendments in the July 2015 Final Rule included, for both Appendix A
and
[[Page 27056]]
Appendix B: (1) Updating the referenced test method to ANSI/ASHRAE
Standard 32.1-2010,''Methods of Testing for Rating Vending Machines for
Sealed Beverages,'' (``ANSI/ASHRAE Standard 32.1-2010''), (2)
incorporating amendments to clarify several ambiguities in ANSI/ASHRAE
Standard 32.1-2010, (3) eliminating the requirement to test at the 90-
degree Fahrenheit (``[deg]F'') ambient test condition, (4) clarifying
the test procedure for combination vending machines, (5) clarifying the
requirements for loading of BVMs under the DOE test procedure, (6)
specifying the characteristics of a standard test package, (7)
clarifying the average next-to-vend beverage temperature test
condition, (8) specifying placement of thermocouples during the DOE
test procedure, (9) establishing provisions for testing at the lowest
application product temperature, (10) clarifying the treatment of
certain accessories during the DOE test procedure, and (11) clarifying
the certification and reporting requirements for covered BVMs. 80 FR
45758, 45760. The July 2015 Final Rule also incorporated amendments in
Appendix B to account for the impact of low-power modes on the measured
daily energy consumption (``DEC'') of BVMs. Id.
II. Request for Information
DOE is publishing this RFI to collect data and information during
the early assessment review to inform its decision, consistent with its
obligations under EPCA, as to whether the Department should proceed
with an amended test procedure rulemaking, and if so, to assist in the
development of proposed amendments. Accordingly, in the following
sections, DOE has identified specific issues on which it seeks input to
aid in its analysis of whether an amended test procedure for BVMs would
more accurately or fully comply with the requirement that the test
procedure produces results that measure energy use during a
representative average use cycle for the product, and not be unduly
burdensome to conduct. (42 U.S.C. 6293(b)(3)) DOE also welcomes
comments on other issues relevant to its early assessment that may not
specifically be identified in this document.
A. Scope and Definitions
BVMs are commercial refrigerators (as defined at 10 CFR 431.62)
that cool bottled or canned beverages and dispense the bottled or
canned beverages on payment. 10 CFR 431.292. The defined equipment
classes for BVMs include Class A, Class B, Combination A, and
Combination B.
Class A means a BVM that is not a combination vending machine and
in which 25 percent or more of the surface area on the front side of
the beverage vending machine is transparent.
Class B means a BVM that is not considered to be Class A and is not
a combination vending machine.
Combination A means a combination vending machine where 25 percent
or more of the surface area on the front side of the beverage vending
machine is transparent.\4\
---------------------------------------------------------------------------
\4\ As provided in 10 CFR 429.134(j)(2), the determination of
percent transparent surface does not include the surface area
surrounding any compartments that are not designed to be
refrigerated (as demonstrated by the presence of temperature
controls), whether or not it is transparent.
---------------------------------------------------------------------------
Combination B means a combination vending machine that is not
considered to be Combination A.
Combination vending machine means a BVM containing two or more
compartments separated by a solid partition, that may or may not share
a product delivery chute, in which at least one compartment is designed
to be refrigerated, as demonstrated by the presence of temperature
controls, and at least one compartment is not. 10 CFR 431.292.
Issue 1: DOE requests comment on whether the existing BVM and
equipment class definitions require any further clarification. For
example, DOE does not include a definition for the term ``dispense''
within the BVM definition. DOE requests information on whether it
should define ``dispense'' to better differentiate between BVMs and
other commercial refrigerators as defined in 10 CFR 431.62, and if so,
DOE requests comment on what definition would be appropriate.
Issue 2: DOE requests comment on whether the current definition for
combination vending machine adequately differentiates between fully
refrigerated BVMs and BVMs designed to have both refrigerated and non-
refrigerated compartments. For example, DOE seeks feedback on whether
the presence of additional features (e.g., refrigerated airflow as
indicated by the presence of air ducts or air deflectors) should be
included in the definition of combination vending machine to determine
whether a compartment is refrigerated. DOE also requests comment on
whether the term ``solid partition'' in the definition of combination
vending machine needs further specificity, and if so, what should be
stated to further specify the term.
Issue 3: DOE requests comment on whether any additional changes or
clarifications are needed to the existing BVM equipment class
definitions.
Issue 4: DOE requests information on whether any additional BVM
categories exist within the current equipment classes that would
require separate or additional test provisions. If such equipment is
identified, DOE requests comment on how the scope of the existing test
procedure should be expanded to include these machines and whether
additional test procedures would be needed to provide representative
test results of such equipment.
B. Test Procedure
DOE's current test procedure in Appendix B incorporates by
reference ANSI/ASHRAE Standard 32.1-2010 and provides additional
instructions and methods to address test setup, conduct, and
calculations. The test procedure generally requires measuring BVM
performance under stable conditions over a 24-hour test period,
allowing the BVM to be in accessory low power mode for the final 6
hours of the test period,\5\ if applicable. Section 2.2.3 and 2.2.4 of
Appendix B. A default payment mechanism energy consumption value is
added to the primary rated energy consumption per day.\6\ Section
2.2.5.1 of Appendix B. If the BVM has refrigeration low power mode,\7\
the measured energy consumption is reduced by a fixed percentage.\8\
Section 2.3.2 of Appendix B. The test procedure also includes
provisions for determining
[[Page 27057]]
refrigerated volume and vendible capacity. Section 3 of Appendix B.
---------------------------------------------------------------------------
\5\ ``Accessory low power mode'' means a state in which a
beverage vending machine's lighting and/or other energy-using
systems are in low power mode, but that is not a refrigeration low
power mode. Functions that may constitute an accessory low power
mode may include, for example, dimming or turning off lights, but
does not include adjustment of the refrigeration system to elevate
the temperature of the refrigerated compartment(s). Section 1.2,
Appendix B.
\6\ Section 2.2.5.1 of Appendix B defines a default payment
mechanism energy consumption of 0.20 kWh/day.
\7\ ``Refrigeration low power mode'' means a state in which a
beverage vending machine's refrigeration system is in low power mode
because of elevation of the temperature of the refrigerated
compartment(s). To qualify as low power mode, the unit must satisfy
the requirements described in section 2.3.2.1 of Appendix B. Section
1.2, Appendix B.
\8\ Section 2.3.2 of Appendix B specifies that for BVMs with a
refrigeration low power mode, multiply the value determined in
section 2.3.1 of Appendix B (which represents the sum of the default
payment mechanism energy consumption value and the primary rated
energy consumption per day) by 0.97 to determine the daily energy
consumption of the unit tested. Section 2.3.2.1 of Appendix B
provides a validation test method to verify the existence of a
refrigeration low power mode.
---------------------------------------------------------------------------
1. Updates to Industry Standards
As discussed, DOE's BVM test procedure in Appendix B incorporates
by reference ANSI/ASHRAE Standard 32.1-2010, which was the most current
version of the industry standard available at the time of the July 2015
Final Rule. DOE specifically references section 3, ``Definitions'';
section 4, ``Instruments''; section 5, ``Vendible Capacity''; section
6, ``Test Conditions''; section 7.1, ``Test Procedures--General
Requirements''; and section 7.2, ``Energy Consumption Test'' of ANSI/
ASHRAE Standard 32.1-2010. Appendix B includes some exceptions to these
references, and in cases of conflict between Appendix B language and
the requirements of ANSI/ASHRAE Standard 32.1-2010, the language in
Appendix B takes precedence. See section 1 of Appendix B.
At the time of the July 2015 Final Rule analysis, DOE was aware of
ongoing industry meetings to consider updates to ASHRAE Standard 32.1.
DOE participated in those industry meetings and, to the extent
possible, sought to align its test procedure with the expected updates
to ASHRAE Standard 32.1. 80 FR 45758, 45762.
On February 2, 2017, ANSI and ASHRAE approved the latest version of
Standard 32.1, ANSI/ASHRAE Standard 32.1-2017, ``Methods of Testing for
Rating Vending Machines for Sealed Beverages,'' (``ANSI/ASHRAE Standard
32.1-2017'').
Many of the revisions included in ANSI/ASHRAE Standard 32.1-2017
harmonize the industry standard with the existing DOE test procedure.
However, some substantive differences between DOE's test procedure at
Appendix B and ANSI/ASHRAE Standard 32.1-2017 remain, notably the
following:
(1) Section 2.2.4 of Appendix B contains provisions for testing
accessory low power mode, and section 2.3.2 of Appendix B accounts for
refrigeration low power mode; whereas ANSI/ASHRAE Standard 32.1-2017
contains no such provisions (and specifically prohibits operation in
low-power mode during testing, per section 7.2.2.6.2).
(2) Section 2.1.3 of Appendix B provides instructions for testing
BVMs that are not capable of maintaining an integrated average
temperature of 36 [deg]F 1 [deg]F during the 24-hour test
period; whereas ANSI/ASHRAE Standard 32.1-2017 contains no such
provisions. See section II.B.5 for additional discussion of lowest
application product temperatures.
(3) Section 2.2.1.4 of Appendix B specifies a ``standard product''
consisting of standard 12-ounce aluminum beverage cans filled with a
liquid with a density of 1.0 grams per milliliter (``g/mL'') 0.1 g/mL at 36 [deg]F; whereas ANSI/ASHRAE Standard 32.1-2017
specifies using a 33 percent propylene glycol/67 percent water
solution. See section II.B.4 for additional discussion of standard
product characteristics.
(4) Section 2.2.5.1 of Appendix B provides instructions for payment
mechanisms that cannot be disconnected during testing (if the payment
mechanism is not removed, Appendix B requires it to be in place but de-
energized, or set to the lowest energy consuming state if it cannot be
de-energized) and specifies a default payment mechanism energy
consumption of 0.20 kWh/day; whereas ANSI/ASHRAE Standard 32.1-2017
contains no such provisions. See section II.B.6 for additional
discussion of payment mechanisms.
(5) Section 2.2.3 of Appendix B requires energy management systems
to be disabled and energy-saving features that cannot be disabled to be
set to their most energy-consuming settings; whereas ANSI/ASHRAE
Standard 32.1-2017 also requires that energy management systems be
disabled, but does not address other energy-saving features that cannot
be disabled.
(6) Sections 2.2.5.2 through 2.2.5.10 of Appendix B provide
additional setup instructions regarding certain equipment accessories
(i.e., internal lighting; external customer display signs, lights, and
digital screens; anti-sweat or other electric resistance heaters;
condensate pan heaters and pumps; illuminated temperature displays;
condensate filters; security covers; general purpose outlets; and
crankcase heaters and other electric resistance heaters for cold
weather); whereas ANSI/ASHRAE Standard 32.1-2017 provides instructions
for only a subset of these accessories (i.e., video screens and
lighting).
(7) Section 2.2.2 of Appendix B prohibits routing thermocouple
wires and other measuring equipment through the dispensing door;
whereas ANSI/ASHRAE Standard 32.1-2017 contains no such prohibition
(only that they be installed in a manner that does not affect energy
performance).
(8) Section 2.3.3 of Appendix B provides rounding instructions on
energy consumption results; whereas ANSI/ASHRAE Standard 32.1-2017
contains no such rounding instructions.
(9) ANSI/ASHRAE Standard 32.1-2017 provides an additional recovery
test (to determine the product temperature recovery time of the BVM
when loaded with product at a certain temperature) and a vend test (to
determine how much cold product a BVM will deliver when bottles, cans,
or other sealed packages are vended at a rate of two per minute, 3
hours after a half-full machine is refilled with product at a specified
beverage temperature); whereas Appendix B contains no such tests. These
tests assess product temperature recovery and vending performance but
do not factor into the energy use measurement.
Issue 5: DOE requests comment on whether it should update its test
procedure to incorporate by reference ANSI/ASHRAE Standard 32.1-2017.
Issue 6: DOE requests comment on whether any of the updates
included in ANSI/ASHRAE Standard 32.1-2017 would affect measured energy
consumption of BVMs, and if so, how. Specifically, DOE requests comment
on the impact of any such changes to the representativeness of the
measurements and the associated impact to test burden.
Issue 7: DOE also requests comment on the identified differences
between the current DOE test procedure and ANSI/ASHRAE Standard 32.1-
2017, including comment on which approach is more appropriate for
testing BVMs, and why.
Issue 8: DOE requests comment on any known deficiencies in ANSI/
ASHRAE Standard 32.1-2017 that DOE may consider addressing in any
future amendments to the BVM test procedure.
2. Ambient Test Conditions
Section 2.1.2 of Appendix B requires testing and rating BVM
performance in a 75 [deg]F ambient temperature with a 45 percent
relative humidity. Prior to the July 2015 Final Rule, the DOE test
procedure incorporated by reference ANSI/ASHRAE Standard 32.1-2004,
which included two ambient test conditions: 75 [deg]F with a 45 percent
relative humidity and 90 [deg]F with a 65 percent relative humidity.
However, compliance with DOE's energy conservation standard was
determined based on performance at only the 75 [deg]F with a 45 percent
relative humidity test condition. In the July 2015 Final Rule, DOE
removed the requirement to conduct testing at the 90 [deg]F with a 65
percent relative humidity test condition. 80 FR 45758, 45764-45765.
During the rulemaking leading to the July 2015 Final Rule, DOE
estimated that 18 percent of Class B and Combination B BVMs are
installed outdoors. 80 FR 45758, 45765. DOE determined that, although
these BVMs
[[Page 27058]]
would experience different ambient conditions than in the test
procedure, it would not be feasible to test at all the conditions BVMs
may experience in the field. Id. DOE determined that the 75 [deg]F with
a 45 percent relative humidity test condition provides a reasonable and
comparable representation of energy performance for all BVMs. Id. In
ANSI/ASHRAE Standard 32.1-2017, the 90 [deg]F with a 65 percent
relative humidity test condition for the energy consumption test was
removed, and the standard designated the 75 [deg]F with a 45 percent
relative humidity test condition as the singular test condition.
If certain BVMs are specifically designed to operate in unique
ambient conditions (i.e., are intended for use only in the unique
condition and are not optionally installed indoors, as are most BVMs),
testing at a different ambient condition may better represent actual
average energy use in the field.
Issue 9: DOE requests comment regarding specification of a single
test condition of 75 [deg]F with a 45 percent relative humidity.
Specifically, DOE requests data on the number of BVMs that operate
outdoors or in other unique environments, and the associated ambient
conditions for those environments.
Issue 10: Additionally, DOE seeks information on how to identify
and define outdoor BVMs that could be considered for additional or
different test conditions. For example, DOE requests comment on whether
BVMs that operate outdoors or in other unique environments have design
characteristics that impact the measured energy consumption at a test
condition of 75 [deg]F with a 45 percent relative humidity. DOE
requests comment on and data for the appropriate test methods to
represent their energy consumption during average use (or if the
existing test at 75 [deg]F with a 45 percent relative humidity is
representative), as well as the costs associated with those methods.
3. Test Procedure for Combination BVMs
As described in section II.A, DOE defines ``combination vending
machine'' as a BVM containing two or more compartments separated by a
solid partition, that may or may not share a product delivery chute, in
which at least one compartment is designed to be refrigerated, as
demonstrated by the presence of temperature controls, and at least one
compartment is not. 10 CFR 431.292. Section 2.2.1.3 of Appendix B
specifies that the non-refrigerated compartments of combination BVMs
must not be loaded with any standard products or other vendible
merchandise during testing. Sections 7.2.2.2 and 7.2.2.7 of ANSI/ASHRAE
Standard 32.1-2017 require combination BVMs not to be loaded with any
standard products, test packages, or other vendible merchandise in the
non-refrigerated compartments, but that the non-refrigerated
compartments be lighted as in normal operation.
The thermal mass of any items loaded into the non-refrigerated
compartments (or lack of thermal mass for an unloaded compartment) of
combination BVMs may affect the measured DEC. Additionally, the thermal
mass of any merchandise stored in the non-refrigerated compartments can
vary significantly depending on the type of merchandise loaded into the
combination BVM. The current approach of requiring no load in the non-
refrigerated compartments addresses the potential variability
associated with this thermal load; however, DOE seeks feedback on
whether requiring some load in the non-refrigerated compartments may
better represent the average energy use of combination BVMs.
Issue 11: DOE requests comment on the typical thermal mass of
merchandise loaded into the non-refrigerated compartments of
combination BVMs and the potential impact of such a load on tested
energy consumption.
4. Characteristics of the Standard Product
Section 2.2.1.4 of Appendix B specifies the standard products to be
used for testing, which include the following: 12-ounce aluminum
beverage cans filled with a liquid with a density of 1.0 grams per
milliliter (``g/mL'') 0.1 g/mL at 36 [deg]F; or, for
product storage racks that are not capable of vending 12-ounce cans,
but are capable of vending 20-ounce bottles, 20-ounce plastic bottles
filled with a liquid with a density of 1.0 g/mL 0.1 g/mL at
36 [deg]F; or, for product storage racks that are not capable of
vending 12-ounce cans or 20-ounce bottles, the packaging and contents
specified by the manufacturer in product literature as the standard
product (i.e., the specific merchandise the refrigerated bottled or
canned beverage vending machine is designed to vend). In the July 2015
Final Rule, DOE discussed the possibility of considering other standard
products, including slimline cans, milk cartons, aseptic packs,
pouches, and energy drinks. 80 FR 45758, 45768. However, DOE determined
that the standard product for BVMs not capable of vending 12-ounce cans
or 20-ounce bottles is the product specified by the manufacturer in
product literature. Id.
Vendible product types other than 12-ounce cans or 20-ounce bottles
may now be used more frequently than at the time of the analysis
leading to the July 2015 Final Rule. DOE may consider adding
descriptions of such refrigerated beverage containers and contents if
they are commonly used and have characteristics that can be defined for
use across BVM manufacturers (i.e., the standard product as described
would not be applicable to only one BVM manufacturer).
Additionally, DOE is aware of certain BVMs that are marketed to
vend both beverages and food, but do not contain a solid partition that
separates the shelves or compartments intended for refrigerated bottled
or canned beverages from those intended for other merchandise. Without
a solid partition, these BVM models would not meet the definition of
combination vending machine and would instead be classified as either
Class A or Class B BVMs. If the non-beverage shelves of these BVMs are
not capable of vending 12-ounce cans or 20-ounce bottles, the standard
product for testing must be the packaging and contents specified by the
manufacturer in product literature as the standard product per section
2.2.1.4 or Appendix B. DOE seeks information on whether to specify
additional instructions for loading and measuring temperatures of such
non-beverage packages to reduce test variability.
Issue 12: DOE requests comment on whether the currently defined
standard products (i.e., the products comprising the BVM test load) are
representative of average BVM use.
Issue 13: DOE seeks feedback on whether any additional products
should be defined as standard products for BVMs that are not capable of
vending 12-ounce cans or 20-ounce bottles to limit variability in
testing. If so, DOE requests data and information on the extent to
which BVMs currently vend such products and the extent to which BVMs
are stocked exclusively with such products (and no other non-standard
products).
Issue 14: DOE also requests detailed descriptions of such products,
including typical dimensions, materials, and contents, and any data
showing whether different standard products affect measured energy use.
Issue 15: DOE requests feedback on the appropriate loading
requirements for refrigerated shelves of BVMs that are designed to
dispense merchandise other than bottled or canned beverages, including
non-beverage merchandise. If these shelves should be loaded, DOE
[[Page 27059]]
requests feedback on the applicability of the standard product
instructions specified in section 2.2.1.4 of Appendix B for these
shelves and on the sensor placement instructions specified in section
2.2.2 of Appendix B.
As discussed in section II.B.1, section 7.1.5.1 of ANSI/ASHRAE
Standard 32.1-2017 requires the beverage temperature test packages to
be filled with a 33 percent propylene glycol/67 percent water solution.
ANSI/ASHRAE Standard 32.1-2017 does not specify whether these glycol/
water percentages are based on weight or volume. Section 5.1 of ANSI/
ASHRAE Standard 32.1-2017 also specifies that standard sealed beverages
are 12-ounce cans, 20-ounce bottles, or the sealed beverage specified
by the manufacturer. Section 5.1 does not provide any other reference
to the liquid in the containers.
Issue 16: DOE requests comment on whether the standard products or
standard test packages as defined in Appendix B sections 2.2.1.4 and
2.2.1.5, respectively, require any further specifications. For example,
in lieu of the existing density specifications, DOE seeks feedback on
whether it should specify the contents of the test containers (e.g.,
the 33 percent propylene glycol/67 percent water solution (and whether
these percentages are based on weight or volume) as specified in
section 7.1.5.1 of ANSI/ASHRAE Standard 32.1-2017).
5. Lowest Application Product Temperature
Section 2.1.1 of Appendix B requires that the integrated average
temperature (``IAT'') of the BVM be 36 [deg]F 1 [deg]F
over the test period. For BVMs that are designed to operate at
temperatures higher than 36 [deg]F and are not capable of maintaining
an IAT at 36 [deg]F 1 [deg]F for testing, section 2.1.3 of
Appendix B requires testing such equipment at its lowest application
product temperature, defined as the lowest IAT the BVM is capable of
maintaining at stable conditions.
In the July 2015 Final Rule, DOE stated that it would monitor its
certification data and would take any necessary corrective actions if a
significant portion of models are certified under the lowest
application product temperature provisions. 80 FR 45758, 45773-45774.
For any BVM tested and rated using the lowest application product
temperature provisions in Appendix B, DOE requires that manufacturers
include the temperature in their certification reports. 10 CFR
429.52(b)(2)(ii). DOE's compliance certification database \9\ lists all
BVM models certified to DOE, including the lowest application product
temperature used for rating each model, if applicable. Of the 137
individual models included in the compliance certification database, 12
individual models (4 basic models) from one manufacturer are rated at
lowest application product temperatures between 37.9 [deg]F and 41.3
[deg]F.\10\ Models had previously been certified to DOE (and are not
included in the current DOE compliance certification database) as being
rated at a lowest application product temperature below the 36 1 [deg]F IAT range required in the DOE test procedure. For
example, models from one manufacturer were previously rated at an IAT
of 32 [deg]F (indicating that those BVMs could not operate as warm as
36 1 [deg]F).

---------------------------------------------------------------------------
Issue 17: DOE requests comment on whether the lowest application
product temperature provisions are appropriate for testing BVMs not
capable of maintaining IAT of 36 [deg]F 1 [deg]F. If not,
DOE requests comment on what test procedures would better represent
energy consumption during average use for such equipment, including,
for example, whether Appendix B should include additional IATs for
rating BVMs.
Issue 18: DOE further requests comment on whether Appendix B should
include additional instructions for testing those BVMs capable of
maintaining temperatures only below the 36 [deg]F 1 [deg]F
range (e.g., testing such BVMs at the highest thermostat setting).
6. Payment Mechanisms
Section 2.2.5.1 of Appendix B requires testing BVMs with no payment
mechanism in place, the payment mechanism in-place but de-energized, or
the payment mechanism in place but set to the lowest energy consuming
state, if it cannot be de-energized. A default payment mechanism energy
consumption value of 0.20 kilowatt-hours per day (``kWh/day'') is added
to the primary rated energy consumption per day, according to section
2.3 of Appendix B. In section 7.1.2.2. of ANSI/ASHRAE Standard 32.1-
2017, payment mechanisms are required to be disconnected during
testing.
DOE established the 0.20 kWh/day value based on a weighted average
energy consumption of 25 different payment mechanisms available at the
time of the July 2015 Final Rule. These included 11 coin mechanisms, 11
bill validators, and 3 credit card readers. 80 FR 45758, 45777.
Since the publication of the July 2015 Final Rule, the prevalence
of different payment mechanisms for BVMs may have shifted. For example,
credit card readers may be more common in the field compared to coin
mechanisms or bill validators, or BVMs may incorporate all types of
payment mechanisms. Based on the July 2015 Final Rule data, credit card
readers had the highest daily energy consumption. If such a shift has
occurred in the market, an amended payment mechanism energy adder may
provide results that are more representative of average energy use.
Additionally, if BVMs as sold or shipped now typically include payment
mechanisms, a direct test of energy consumption rather than a fixed
energy use adder may be more representative of average energy use.
Issue 19: DOE requests comment on whether BVMs are typically sold
and shipped with payment mechanisms in place. If not, DOE requests
information on the types of payment mechanisms typically installed on
BVMs and their associated energy use.
Issue 20: DOE seeks feedback on whether the current 0.20 kWh/day
energy use assigned to payment mechanisms is representative of the
current BVM market.
7. Low Power Modes
Appendix B incorporates definitions and test requirements for two
types of low power modes \11\ (i.e., accessory low power mode and
refrigeration low power mode). Section 7.2.2.6.2 of ANSI/ASHRAE
Standard 32.1-2017 requires that low power modes not be allowed to
operate during testing.
---------------------------------------------------------------------------
\11\ ``Low power mode'' means a state in which a beverage
vending machine's lighting, refrigeration, and/or other energy-using
systems are automatically adjusted (without user intervention) such
that they consume less energy than they consume in an active vending
environment. Section 1.2, Appendix B.
---------------------------------------------------------------------------
In the July 2015 Final Rule, DOE acknowledged that the two types of
low power modes incorporated into the test procedure (accessory low
power mode and refrigeration low power mode) may not address all forms
of low power modes available in the BVM market. DOE identified
``learning-based'' energy management controls that use historic sales
and traffic data to predict times of high and low traffic; however, DOE
did not propose a test procedure for such controls, as it would be
difficult to develop a repeatable test procedure to evaluate the energy
savings of such
[[Page 27060]]
controls during a 24-hour test in a laboratory. 80 FR 45758, 45786.
Issue 21: DOE requests comment on the availability of additional
low power modes for BVMs, including any ``learning-based'' energy
management controls. If such modes are available, DOE seeks data and
information on the typical operating times and associated energy
consumptions of BVMs in these modes.
Issue 22: DOE also seeks feedback on whether a test procedure to
account for operation in these low power modes would better reflect the
representative average energy use of BVMs, and if so, what would be the
appropriate test methods as well as the associated test burden and
costs.
a. Accessory Low Power Mode
Section 1.2 of Appendix B defines accessory low power mode as a
state in which a BVM's lighting and/or other energy-using systems are
in low power mode, but that is not a refrigeration low power mode.
Functions that may constitute an accessory low power mode may include,
for example, dimming or turning off lights, but does not include
adjustment of the refrigeration system to elevate the temperature of
the refrigerated compartment(s). Section 2.2.4 of Appendix B states
that accessory low power mode may be engaged for the final 6 hours of
the 24-hour test period and requires that the BVM be operated in the
lowest energy-consuming lighting and control settings for testing this
mode. Section 2.2.4 also requires that any automatic activation of
refrigeration low power modes be prevented during the accessory low
power mode test period.
The 24-hour test procedure starts after a BVM achieves
stabilization as determined in vending mode. Because the test period
ends with 6 hours of operation in accessory low power mode, when the
mode is engaged for testing, the BVM would end the test in a different
operating state than at the start of the test. Although the
refrigeration system and cabinet temperatures would likely not change
with operation in an accessory low power mode (because accessory low
power mode does not include adjustment of the refrigeration system to
elevate the temperature of the refrigerated compartment), some
transient recovery period may be required for a BVM to return to stable
operation in vending mode after operating in accessory low power mode
for 6 hours. If such a recovery period exists, testing the accessory
low power mode during the middle of the 24-hour test period may be more
representative by capturing any transition periods between operating
modes.
Issue 23: DOE requests comment on whether BVMs require any recovery
period following operation in accessory low power mode to return to
stable operation in vending mode. If so, DOE requests test data
indicating the effect of such operating periods and seeks feedback on
whether the accessory low power mode test period should occur at some
other point during the 24-hour test period.
Issue 24: Additionally, DOE requests information regarding testing
the accessory low power mode during a period other than at the end of
the 24-hour test period, specifically on any potential drawbacks or
test burdens that may result.
In the July 2015 Final Rule, DOE stated that BVMs may employ a
variety of control strategies and control a variety of different
components in accessory low power mode. 80 FR 45758, 45785. DOE
established testing under the settings representing the maximum energy
savings to avoid potential repeatability issues associated with
identifying appropriate test control settings for BVMs with various
types of accessory low power modes. Id.
Issue 25: DOE requests comment on the typical average duration a
BVM operates in accessory low power mode per day, if applicable.
Issue 26: DOE also seeks information on the control settings users
apply for accessory low power mode in the field (i.e., whether the
lowest energy consumption settings for lighting and controls are
representative of average use in accessory low power mode).
Issue 27: DOE also requests comment on whether multiple accessory
low power mode test settings may be appropriate for BVMs offering
various control settings.
b. Refrigeration Low Power Mode
Section 1.2 of Appendix B defines refrigeration low power mode as a
state in which a BVM's refrigeration system is in low power mode
because of elevation of the temperature of the refrigerated
compartment(s). Section 2.3.2.1 of Appendix B includes provisions for
confirming the presence of a refrigeration low power mode, either
through an increase in average next-to-vend beverage temperature or
lack of compressor operation. Unlike accessory low power mode, Appendix
B does not include a direct test of refrigeration low power mode.
Instead, BVMs with refrigeration low power mode receive a 3-percent
reduction in DEC as measured. Section 2.3.2 of Appendix B.
In the July 2015 Final Rule, DOE determined that a 3-percent energy
reduction was more appropriate than a physical test of refrigeration
low power mode because refrigeration low power modes are extremely
variable in their control strategies and operation and may require
instructions from the manufacturer to accommodate specific provisions
of a physical test. DOE stated that a physical test would reduce
consistency and repeatability and would make the method impractical to
implement. 80 FR 45758, 45785.
DOE established the 3-percent credit for refrigeration low power
mode by testing several BVMs with this mode.\12\ DOE noted in the July
2015 Final Rule that this value is an average that is representative of
the common types of refrigeration low power modes available in the
marketplace. 80 FR 45758, 45786.
---------------------------------------------------------------------------
\12\ DOE described the method for determining the 3-percent
credit in detail in the notice of proposed rulemaking that preceded
the July 2015 Final Rule. 79 FR 46908, 46925-46926 (Aug. 11, 2014).
---------------------------------------------------------------------------
Issue 28: DOE requests comment on whether any amendments are needed
to either the definition of refrigeration low power mode or the
corresponding refrigeration low power mode validation test method.
Issue 29: DOE seeks feedback on whether any BVM operating modes
exist that should be considered a refrigeration low power mode but
cannot meet the current definition or validation test method (e.g.,
operating modes with little or no increase in refrigerated compartment
temperature with some amount of compressor operation).
Issue 30: DOE requests comment on the current approach of applying
a 3-percent energy reduction for any BVMs determined to have a
refrigeration low power mode. Specifically, DOE requests comment on
whether a physical test to account for actual unit energy reduction
associated with refrigeration low power mode is feasible, or whether
any test method for such an approach currently exists, and on the
burden associated with running such a test.
Issue 31: DOE requests comment on whether the 3-percent energy
reduction is appropriate for BVMs with refrigeration low power mode.
DOE seeks data on BVM operation in refrigeration low power mode,
including the amount of time spent in such a mode and the associated
energy consumption.
8. Reloading and Recovery Period
As stated in Section II.B.1, ANSI/ASHRAE Standard 32.1-2017
provides an additional recovery test (to determine the product
temperature recovery time
[[Page 27061]]
of the BVM when loaded with product at a certain temperature), whereas
Appendix B contains no such test. This recovery test assesses product
temperature recovery performance of the BVM but does not include a
measurement of the corresponding energy consumption. Table 2 in ANSI/
ASHRAE Standard 32.1-2017 lists the reloaded sealed-beverage
temperature, 90 [deg]F, and the final instantaneous average next-to-
vend beverage temperature, 40 [deg]F, for the recovery test.
Additionally, Table 4 in ANSI/ASHRAE Standard 32.1-2017 lists the door
open durations, between 10 and 20 minutes, required during the recovery
test while reloading the BVM.
The existing DOE test procedure considers BVM performance only
during stable operation (including any operation in accessory low power
mode). During typical use, BVMs are regularly opened and restocked with
warmer beverages. Accounting for BVM energy use during restocking
periods and the subsequent product temperature recovery periods may
better represent the actual energy use of BVMs during normal operation.
Issue 32: DOE requests comment and supporting data on whether BVM
restocking and the subsequent product temperature recovery represent a
significant energy consumption for BVMs relative to the existing test
procedure.
Issue 33: DOE requests comment and supporting data regarding the
applicability of the recovery test described in ANSI/ASHRAE Standard
32.1-2017 for measuring the energy consumption associated with
restocking and product temperature recovery.
Issue 34: DOE requests comment and supporting data on the frequency
and duration of door openings required to reload BVMs.
9. Alternate Refrigerants
In an April 10, 2015 final rule, the Environmental Protection
Agency listed propane (R-290), isobutane (R-600a), and the hydrocarbon
blend R-441A as acceptable refrigerants for use in BVMs, subject to a
150-gram charge limit per refrigeration circuit and other safety
measures to address flammability. 80 FR 19454, 19491. Due to the
flammability of these refrigerants, BVMs using hydrocarbon refrigerants
may need to implement additional controls and components to mitigate
the risk of ignition from any potential refrigerant leaks. The need for
such controls also may vary depending on the intended installation
location for BVMs.
DOE is interested in understanding what additional components and
controls manufacturers may need to add to their equipment to transition
to alternative refrigerants, including propane, and whether the test
procedure requires any updates to account for any corresponding energy
use. DOE's expectation is that such controls would always be active and
would not require specific test procedure instructions; however, DOE
requests information on whether multiple control settings are available
for these components, and if so, what would be the representative test
settings.
Issue 35: DOE requests comment on what additional components and
controls manufacturers may need to add to their equipment when
designing BVMs with alternative refrigerants and on the typical
settings used for such components and controls, if multiple settings
are available. DOE requests comment on whether any test procedure
modifications are necessary to account for the energy consumption
associated with these components and controls and any corresponding
impact on testing burden.
10. Connected Functions
The current DOE test procedure for BVMs does not include test
requirements specifically for connected or smart features. Section
2.2.5 of Appendix B generally requires all components necessary to
provide sufficient functionality for cooling and vending products in
field installations (i.e., product inventory, temperature management,
product merchandising (including, e.g., lighting or signage), product
selection, and product transport and delivery) to be in place during
testing and set to the maximum energy-consuming setting if manually
adjustable. Other components not necessary for such functionality are
de-energized or set to their lowest energy consuming state.
Issue 36: DOE requests comment on the prevalence of connected
functions in BVMs. DOE seeks information on what BVM functions are
associated with these connected modes, how often they are used, and
their corresponding impacts on energy use.
Issue 37: DOE also requests comment on whether the existing DOE
test procedure instructions for accessories in section 2.2.5 of
Appendix B adequately address test settings for connected functions in
BVMs.
