Energy Conservation Program: Test Procedures for Packaged
Terminal Air Conditioners and Packaged Terminal Heat Pumps
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Notice of proposed rulemaking.
-----------------------------------------------------------------------
SUMMARY: In this notice of proposed rulemaking (NOPR), the U.S.
Department of Energy (DOE) proposes to revise its test procedures
established under the Energy Policy and Conservation Act (EPCA) for
packaged terminal air conditioners (PTACs) and packaged terminal heat
pumps (PTHPs). The proposed amendments would specify an optional break-
in period, explicitly require that wall sleeves be sealed, allow for
the pre-filling of the condensate drain pan, require that ASHRAE
Standard 16 be the sole method of test when measuring the cooling
capacity for PTACs and PTHPs under ANSI/AHRI Standard 310/380-2004, and
require testing with 14-inch deep wall sleeves and the filter option
most representative of a typical installation. These updates fulfill
DOE's obligation under EPCA to review its test procedures for covered
equipment at least once every 7 years and either amend the applicable
test procedures or publish a determination in the Federal Register not
to amend them. DOE will hold a public meeting to discuss and receive
comments on the issues presented in this notice.
DATES: DOE will hold a public meeting on April 28, 2014, from 9 a.m. to
4 p.m., in Washington, DC. The meeting will also be broadcast as a
webinar. See section V, ``Public Participation,'' for webinar
registration information, participant instructions, and information
about the capabilities available to webinar participants.
DOE will accept comments, data, and information regarding this
notice of proposed rulemaking (NOPR) before and after the public
meeting, but no later than May 27, 2014. See section V, ``Public
Participation,'' for details.

I. Authority and Background
Title III of the Energy Policy and Conservation Act of 1975 (42
U.S.C. 6291, et seq.; ``EPCA'' or, ``the Act'') sets forth a variety of
provisions designed to improve energy efficiency. (All references to
EPCA refer to the statute as amended through the American Energy
Manufacturing Technical Corrections Act (AEMTCA), Public Law 112-210
(Dec. 18, 2012).) Part C of Title III, which for editorial reasons was
redesignated as Part A-1 upon incorporation into the U.S. Code (42
U.S.C. 6311-6317, as codified), establishes the Energy Conservation
Program for Certain Commercial and Industrial Equipment. This equipment
includes packaged terminal air conditioners (PTACs) and packaged
terminal heat pumps (PTHPs), the subjects of today's notice. (42 U.S.C.
6311(1)(I))
Under EPCA, the energy conservation program consists essentially of
four parts: (1) Testing, (2) labeling, (3) Federal energy conservation
standards, and (4) certification and enforcement procedures. The
testing requirements consist of test procedures that manufacturers of
covered equipment must use as the basis for (1) certifying to DOE that
their equipment complies with applicable energy conservation standards
adopted under EPCA, and (2) making representations about the efficiency
of the equipment. Similarly, DOE must use these test procedures to
determine whether the equipment complies with any relevant standards
promulgated under EPCA.
General Test Procedure Rulemaking Process
In 42 U.S.C. 6314, EPCA sets forth the general criteria and
procedures DOE must follow when prescribing or amending test procedures
for covered equipment. EPCA provides in relevant part that any test
procedures prescribed or amended under this section shall 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 shall
not be unduly burdensome to conduct. (42 U.S.C. 6314(a)(2)) In
addition, 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. 6314(b))
DOE is also required by EPCA to conduct an evaluation of test
procedures every seven years for each class of covered equipment
(including PTACs and PTHPs) to determine if an amended test procedure
would more accurately or fully comply with the requirement to be
reasonably designed to produce test results that reflect the energy
efficiency, energy use, and operating costs during a representative
average use cycle. DOE must either prescribe amended test procedures or
publish a notice in the Federal Register regarding its determination
not to amend test procedures. (42 U.S.C. 6314(a)(1)-(2))
Background
DOE's test procedure for PTACs and PTHPs is codified at Title 10 of
the Code of Federal Regulations (CFR) section 431.96. The test
procedure was established on December 8, 2006, in a final rule that
incorporated by reference the American National Standards Institute's
(ANSI) and Air-Conditioning, Heating, and Refrigeration Institute's
(AHRI) Standard 310/380-2004, ``Standard for Packaged Terminal Air-
Conditioners and Heat Pumps'' (ANSI/AHRI Standard 310/380). 71 FR
71340, 71371. ANSI/AHRI Standard 310/380-2004 is incorporated by
reference at 10 CFR 431.95(a)(3) and it references (1) the American
Society of Heating, Refrigerating and Air-Conditioning Engineers
(ASHRAE) Standard 16-1999 (RA2009), ``Method of Testing for Rating Room
Air Conditioners and Packaged Terminal Air Conditioners'' (ASHRAE
Standard 16); (2) ASHRAE Standard 58-1986 (RA2009), ``Method of Testing
for Rating Room Air Conditioner and Packaged Terminal Air Conditioner
Heating Capacity'' (ASHRAE Standard 58); and (3) ASHRAE Standard 37-
1988, ``Methods of Testing for Rating Electrically Driven Unitary Air-
Conditioning and Heat Pump Equipment'' (ASHRAE Standard 37).
On May 16, 2012, DOE published a final rule for commercial heating,
air-conditioning, and water-heating equipment (ASHRAE equipment), which
included amendments to the test procedure for PTACs and PTHPs. These
amendments incorporated a number of sections of ANSI/AHRI Standard 310/
380 by reference. 77 FR 28928, 28990. In today's rulemaking, DOE is
evaluating test procedures for PTACs and PTHPs as required by 42 U.S.C.
6314(a)(1).
On February 22, 2013, DOE published a notice of public meeting and
availability of framework document to consider energy conservations
standards rulemaking for PTACs and PTHPs. 78 FR 12252. In the framework
document, DOE sought comments on issues pertaining to the test
procedure for PTACs and PTHPs, including equipment break-in, wall
sleeve sealing, pre-filling the condensate drain pan, barometric
pressure correction, and differences between the test methods of ASHRAE
Standard 16 and ASHRAE Standard 37. Comments received on these topics
are discussed in section III.
On February 26, 2013, members of the Appliance Standards and
Rulemaking Federal Advisory Committee (ASRAC) unanimously decided to
form a working group to engage in a negotiated rulemaking effort on the
certification of commercial heating, ventilation, and air conditioning
(HVAC) equipment (10 CFR part 431, subparts D, E and F), water heating
(WH) equipment (10 CFR part 431, subpart G), and refrigeration
equipment (10 CFR part 431, subpart C) (Working Group). A notice of
intent to form the Commercial Certification Working Group was published
in the Federal Register on March 12, 2013, following which DOE received
35 nominations. 78 FR 15653. On April 16, 2013, the Department
published a notice of open meeting that announced the first meeting and
listed the 22 nominated individuals that were selected to serve as
members of the Working Group, in addition to two members from ASRAC,
and one DOE representative. 78 FR 22431. Following the meeting, the
Working Group published a set of recommendations, and DOE issued the
Certification of Commercial HVAC, WH, and Refrigeration Equipment NOPR
(Certification of Commercial Equipment NOPR) on February 7, 2014,
summarizing the Working Group's recommendations. 79 FR 8886. The group
proposed a number of test procedure items for PTACs and PTHPs,
including proposals for (1) a standardized wall sleeve to be used
during testing and (2) a standardized filter to be used during testing,
both of which are discussed in today's NOPR.
DOE considers the activity initiated by this proposed rule
sufficient to satisfy the statutory requirement that
[[Page 14188]]
DOE must review its test procedures for all covered equipment,
including PTACs and PTHPs, at least once every 7 years and either amend
the applicable test procedures or publish a determination in the
Federal Register not to amend them. (42 U.S.C. 6314(a)(1))
II. Summary of the Notice of Proposed Rulemaking
In this NOPR, DOE proposes to amend the test procedures for PTACs
and PTHPs in 10 CFR 431, Subpart F, to specify an optional break-in
period, explicitly require that wall sleeves be sealed, allow for the
pre-filling of the condensate drain pan, require that the cooling
capacity for PTACs and PTHPs be determined by testing pursuant to
ASHRAE Standard 16, and require testing with 14-inch deep wall sleeves
and the filter option most representative of a typical installation.
The proposed amendments would explicitly allow PTAC and PTHP
manufacturers the option of using a break-in period (up to 20 hours)
before conducting the test procedure. In this regard, DOE proposes
adding ANSI/AHRI Standard 310/380-2004 to the list of commercial air-
conditioner standards at 10 CFR 431.96(c), which currently provides an
optional break-in period of up to 20 hours for other commercial air-
conditioner equipment types. The proposal would also require any PTAC
or PTHP manufacturer that elects to use a break-in period to certify
the duration of the break-in period it used for each basic model. DOE
proposes that, as part of the set-up for testing, testers seal gaps
between wall sleeves and the test facility dividing wall. This would
require the PTAC or PTHP wall sleeve to be sealed per manufacturer
specifications or a standard sealing method.
DOE proposes to allow the pre-filling of the condensate drain pan
with water before running the DOE test procedure. This proposed
amendment would allow the unit to reach steady state more quickly,
which would decrease the burden and cost of testing.
DOE proposes to modify the test procedure to require ASHRAE
Standard 16 as the test method for measuring the cooling capacity of
PTACs and PTHPs. DOE would remove all references to ASHRAE Standard 37
as an allowable method of test.
DOE proposes to require testing using a 14-inch deep wall sleeve
and only one filter option, which would be the most typical filter
option that is shipped with the tested unit. These proposed amendments
would remove testing variability resulting from the use of non-standard
equipment.
DOE does not believe that these proposed changes to the PTAC and
PTHP test procedure would result in any additional burden to
manufacturers or result in any changes to the energy efficiency of
current equipment. Rather, the proposed changes would provide
additional clarification regarding how the DOE test procedure should be
conducted.
III. Discussion
A. Break-In Duration
Break-in, also called run-in, refers to the operation of equipment
prior to testing to cause preliminary wear, which may improve measured
performance. DOE understands that many labs commonly incorporate a
break-in period before the start of efficiency tests for air
conditioning equipment. DOE's May 16, 2012 final rule for Small, Large,
and Very Large Commercial Package Air Conditioners and Heat Pumps
(ASHRAE equipment), 77 FR 28928, 28991, added a specification in the
test procedure that allows an optional break-in period of up to 20
hours for many types of commercial air conditioning and heating
equipment and requires that manufacturers record the duration of the
break-in period. However, these amendments do not apply to PTACs or
PTHPs.
DOE is aware that the time required to achieve sufficient break-in
(for stabilizing equipment performance) may depend on ambient
temperature. Generally, the break-in process is conducted outside the
test chamber at room temperature conditions (i.e., 65-85 [deg]F).
However, conducting break-in in the test chamber at elevated ambient
temperatures (i.e., 95 [deg]F outdoor/80 [deg]F indoor) may reduce the
time required to achieve break-in. Using the test chamber for break-in
would likely increase the expense of testing significantly because it
would increase the amount of time that a test unit is in the test
chamber. DOE asked for comment on this issue in the framework document
published on February 22, 2013. 78 FR 12252.
In response, AHRI and Goodman stated that DOE should allow for an
optional break-in period at non-specified ambient conditions for PTAC
and PTHP testing, but did not specify a maximum duration. (AHRI, No. 11
at p. 2; Goodman, No. 13 at p. 1) \1\ The California Investor-Owned
Utilities (CA IOUs, which consists of the Pacific Gas and Electric
Company (PG&E), the Southern California Gas Company (SCGC), the San
Diego Gas and Electric (SDG&E), and Southern California Edison (SCE))
stated that DOE should allow an optional break-in period with a maximum
duration of 20 hours, as allowed in the ASHRAE equipment final rule.
(CA IOUs, No. 12 at pp. 1-2) AHRI and Goodman stated that they do not
have any data to show how the length of break-in time specifically
affects PTAC or PTHP performance; however, Goodman did state that it
has test data for residential air conditioning systems that indicate
that system performance can improve by ``several percentage points over
a 72 hour period.'' AHRI and Goodman further stated that any
manufacturer that elects to use the optional break-in period for AHRI's
certification testing must cover the cost of the break-in period.
(AHRI, No. 11 at p. 2; Goodman, No. 13 at p. 1) AHRI also stated that
breaking-in the equipment in the testing lab may cost around $1500 per
8-hr shift, whereas the only cost of break-in outside the test lab is
the labor required for set-up and the electricity needed to operate the
equipment. (AHRI, No. 11 at p. 2)

that is in the docket of DOE's ``Energy Conservation Program for
Certain Commercial and Industrial Packaged Terminal Air Conditioners
and Packaged Terminal Heat Pumps'' (Docket No. EERE-2012-BT-STD-
0029), which is maintained at www.regulations.gov. This notation
(AHRI, No. 11 at p. 2) indicates that the statement preceding the
reference is found in document number 11 in the docket for the
packaged terminal air conditioner and packaged terminal heat pump
test procedure rulemaking, and appears at page 2 of that document.
---------------------------------------------------------------------------
DOE has concluded that allowing for an optional break-in period
will provide manufacturers more flexibility to produce test results
that more accurately reflect energy efficiency of basic models in a
manner that is representative of their performance without adding
significant testing costs and burdens on the manufacturers. DOE
understands that using a break-in period will generally improve the
measured efficiency of a product by allowing moving parts (such as
compressor mating surfaces) to wear-in to improve efficiency. DOE also
concludes that the use of a break-in period should be at the
manufacturer's discretion. Therefore, DOE proposes adding ANSI/AHRI
Standard 310/380 to the list of commercial air-conditioner standards at
10 CFR 431.96(c), which would provide an optional break-in period of up
to 20 hours. DOE already allows manufacturers of other commercial air-
conditioner equipment the option of a break-in period not to exceed 20
hours, and this change would extend this allowance to manufacturers of
PTACs
[[Page 14189]]
and PTHPs. DOE has not found evidence that break-in periods exceeding
20 hours provide additional efficiency improvements for a PTAC or PTHP.
In addition, DOE is proposing a reporting requirement so that
manufacturers would certify the duration of the break-in period used
during that testing conducted to support the development of the
certified ratings. As such, DOE is proposing to modify the
certification requirements for PTACs and PTHPs that were proposed on
February 14, 2014, 79 FR 8886, 8900, to require the manufacturer to
include the break-in period in the certification report. DOE seeks
comment on this proposal. Please note that a manufacturer must maintain
records underlying its certified rating, which would reflect this
optional break-in period duration pursuant to 10 CFR 429.71. DOE also
notes that ratings derived from an alternative efficiency determination
method (AEDM) would include a break-in period only if the test data
underlying the AEDM also included a run-in period. As background. AEDMs
are computer modeling or mathematical tools that predict the
performance of non-tested basic models. They are derived from
mathematical models and engineering principles that govern the energy
efficiency and energy consumption characteristics of a type of covered
equipment.
If commenters support longer break-in times, DOE requests data
demonstrating that break-in periods longer than 20 hours make a
significant impact on efficiency measurements for this equipment type.
This is identified as issue 1 in section V.E, ``Issues on Which DOE
Seeks Comment.''
B. Wall Sleeve Sealing
PTACs and PTHPs are tested in a testing facility incorporating
rooms, simulating indoor and outdoor ambient test conditions, that are
separated by a dividing wall with an opening in which the test sample
is mounted. In most cases, the test sample is placed in the opening,
and any remaining gaps between the dividing wall and the wall sleeve
around the unit are filled with insulating material. The gap between
the test sample and the insulating material may also be sealed with
duct tape.
ASHRAE Standard 16 states, ``The air conditioner shall be installed
in a manner similar to its normal installation'' (Section 4.2.2). In
normal practice, PTACs and PTHPs are installed within wall sleeves that
are permanently installed and sealed to the external wall of a
building. However, the set-up of the DOE test procedure does not allow
for the permanent installation of the wall sleeves in the partition
cavity. Thus, during testing, the wall sleeve is not necessarily air-
sealed to the wall as it would be in a normal installation in the
field. Air leakage between the outdoor and indoor rooms through gaps
between the wall sleeve and the dividing wall can reduce the measured
capacity and efficiency, which would contribute to test results
unrepresentative of field operation. DOE asked for comment on this
issue in the framework document. 78 FR 12252 (Feb. 22, 2013).
Goodman responded that it will always be a proponent of anything
that is done to the test procedure to minimize the variability of
testing among laboratories, including sealing the wall sleeve.
(Goodman, Framework Public Meeting Transcript at p. 24) \2\ Goodman
noted that adding wall sleeve sealing requirements to the test
procedure would reduce the variability of measured performance from one
lab to another. (Goodman, No. 13 at p. 2) Goodman added that sealing
the wall sleeve leaks would not add a significant amount of time to the
total testing to be done. (Goodman, Framework Public Meeting Transcript
at p. 24) The CA IOUs pointed to section 4.2.2 of ASHRAE Standard 16
(mentioned above), which they believe can be interpreted as a
requirement for wall sleeves to be sealed with the test facility
dividing wall. They also pointed out that guidance as to the level of
sealing necessary for the wall sleeve can be found in section 7.7.4 of
ANSI/AHRI Standard 310/380, which states, ``During the entire test, the
measured air flow rate, L/s (ft3/min), leaking into the indoor portion
shall be considered to be the infiltration rate through the equipment
and shall not exceed 3.1 L/(sm) (2 ft3/(minft)) at the
perimeter of the wall sleeve where it normally projects through the
wall.'' (CA IOUs, No. 12 at p. 2)
---------------------------------------------------------------------------
\2\ A notation in the form ``Scotsman, Public Meeting Transcript
at p. 26'' identifies a comment that DOE has received during a
public meeting and has included in the docket of this rulemaking.
This particular notation refers to a comment: (1) Submitted by
Scotsman; (2) transcribed from the public meeting; and (3) appearing
on page 26 of that document.
---------------------------------------------------------------------------
DOE agrees with Goodman's comments that sealing the wall sleeve
would reduce the variability of testing among laboratories and would
help produce test results that more accurately reflect the energy
efficiency of PTACs and PTHPs. DOE notes that section 4.2.2 of ASHRAE
Standard 16 does not specifically require the wall sleeve to be sealed
to the wall. Section 7.7.4 of ANSI/AHRI Standard 310/380, as the CA
IOUs pointed out, deals with air infiltration testing, both through the
unit and around the unit (i.e., between the wall sleeve and the
opening). Although this air flow is generally measured during tests,
the DOE test procedure for PTACs and PTHPs does not require its
measurement and reporting. Furthermore, this air flow includes
infiltration both through the unit and between the wall sleeve and the
test facility dividing wall opening, so it is not necessarily a good
indicator of whether the wall sleeve seal is tight.
To improve the repeatability of PTAC and PTHP testing, DOE proposes
to require that test facilities, when installing PTACs and PTHPs in the
test chamber, seal all potential leakage gaps between the wall sleeve
and the dividing wall. DOE seeks comments on the sealing of PTAC and
PTHP wall sleeves to the test facility dividing wall, including whether
the type or method of sealing (e.g., duct tape) should be specified,
and whether a test could be developed that, with reasonably low test
burden, could be performed to verify an adequate seal. This is
identified as issue 2 in section V.E, ``Issues on Which DOE Seeks
Comment.''
C. Pre-Filling Condensate Drain Pan
Most PTACs and PTHPs transfer the condensate that forms on the
evaporator to a condensate pan in the unit's outdoor-side where the
outdoor fan distributes the water over the air-inlet side of the
condenser. This process results in evaporative cooling that enhances
the cooling of the outdoor coil in air-conditioning mode. At the
beginning of a test, there may be no water in the condensate pan. As
the test progresses and the unit approaches an equilibrium state of
operation, the condensate level in the drip pan will fill and stabilize
at a constant level. It can take several hours to reach this steady
state.
To accelerate the testing process, test facilities typically add
water to the condensate pan at the beginning of the test rather than
waiting for the unit to generate sufficient condensate to stabilize.
The current test procedure does not indicate whether this practice is
allowed during efficiency testing. DOE sought comment on this issue in
the framework document. 78 FR 12252 (Feb. 22, 2013).
AHRI and Goodman recommended that the condensate pan be pre-filled
with water prior to testing, and stated that any type of water would be
acceptable for pre-filling. (AHRI, No. 11
[[Page 14190]]
at p. 3; Goodman, No. 13 at p. 2) AHRI stated that achieving steady
state conditions with a pre-filled pan takes 2-4 hours, with actual
testing taking an additional 2 hours. If the pan is not prefilled, then
the set-up and stabilization period will take approximately twice as
long. (AHRI, No. 11 at p. 3) Goodman estimated that roughly 1 to 2
hours would be saved from pre-filling the condensate pan. Goodman added
that the lab should document how much water was added to the pan, the
water-source, and its temperature. Goodman also suggested that the
water added be approximately 50 [deg]F to optimize the time to reach
equilibrium. (Goodman, No. 13 at p. 2)
The CA IOUs stated that distilled water should be used (as opposed
to city water) because distilled water is similar in mineral content to
the condensate that would normally fill the drain pan. (CA IOUs, No. 12
at p.3) They also indicated that section 7.6.3 of ANSI/AHRI Standard
310/380 (condensate disposal test section) provides guidance for pre-
filling the condensate drain pan: ``After establishment of the
specified temperature conditions, the equipment shall be started with
its condensate collection pan filled to the overflowing point and shall
be operated continuously for 4 h after the condensate level has reached
equilibrium.'' (CA IOUs, No. 12 at p. 2)
DOE agrees that pre-filling the condensate pan would not alter the
measured results as compared with not pre-filling the condensate pan.
DOE also recognizes that pre-filling the condensate pan may reduce the
time for the unit to achieve steady-state by approximately 1-4 hours,
which would reduce test lab expenses because the PTAC or PTHP would
spend less time in the test chamber. While DOE understands that regular
tap water may have minerals and dissolved solids that could affect the
thermodynamic properties of the condensate, which could then affect the
steady-state behavior of the PTAC or PTHP, DOE does not have
information to indicate whether use of non-distilled water will have a
measurable impact on the performance of the PTAC or PTHP during
testing. Therefore, DOE's proposal does not include requirements that a
specific water type be used to fill the pan.
Additionally, DOE does not have information to indicate whether the
temperature of the water used to prefill the pan will impact the test
result, but acknowledges that the condensate water temperature of the
test will stabilize due to the equilibrium tolerance requirements in
section 6.1.5 of ASHRAE Standard 16. Therefore, DOE's proposal does not
include requirements that water at a specific temperature be used to
fill the pan.
Section 7.6.3 of ANSI/AHRI Standard 310/380, which the CA IOUs
cited as providing guidance for pre-filling the condensate pan, is part
of the procedure for the condensate disposal test designed to ensure
that condensate does not overflow the drain pan. This section is not
part of the general cooling capacity test for PTACs and PTHPs, and does
not contain guidance for condensate temperatures or water types.
DOE proposes to add a provision in its test procedures at 10 CFR
431.96 to allow manufacturers the option of pre-filling the condensate
drain pan before starting the efficiency test. As indicated above, the
provision would not set requirements regarding the water purity or the
water temperature that is to be used. DOE seeks comments on pre-filling
the condensate drain pan, including whether the type and/or temperature
of the water used should be specified in the test procedure and/or
recorded in the test data underlying the results. This is identified as
issue 3 in section V.E, ``Issues on Which DOE Seeks Comment.''
D. ASHRAE Standard 16 vs. ASHRAE Standard 37
ANSI/AHRI Standard 310/380 indicates that either ASHRAE Standard
16-1999 (a calorimeter-based method) or ASHRAE Standard 37-1988 (a
psychrometric-based method) may be used to determine cooling
efficiency. The two test methods have significant differences that may
influence test results, including whether outgoing evaporator air is
allowed to recirculate back into the evaporator. Testing consistency of
PTACs and PTHPs may be improved by requiring all efficiency tests to be
conducted using only one of the two ASHRAE standards. On the other
hand, such an approach may increase test burden, particularly for those
manufacturers that currently use one particular test method (e.g.,
manufacturers who do not have access to a calorimeter test chamber
needed to conduct testing according to ASHRAE Standard 16). DOE asked
for comment on this issue in the framework document. 78 FR 12252 (Feb.
22, 2013).
Goodman and AHRI both stated that there is an ongoing process to
revise ASHRAE Standard 16 that will incorporate aspects of ASHRAE
Standard 37. (AHRI, No. 11 at p. 2; Goodman, Framework Public Meeting
Transcript at p. 29) Goodman stated that it uses both psychrometric and
calorimeter methods for its performance testing. (Goodman, No. 13 at p.
2) AHRI stated that it conducts its cooling verification testing for
PTACs and PTHPs only in calorimeter rooms in accordance with ASHRAE
Standard 16. AHRI also stated that, despite the differences between the
two test methods, the test results between the two methods correlate.
(AHRI, No. 11 at p. 2) AHRI noted that ASHRAE Standard 16 is currently
being revised, and the upcoming release of the standards would likely
include both psychrometric and calorimeter testing methods. AHRI stated
that, upon release of updated ASHRAE Standard 16, ANSI/AHRI Standard
310/380 will likely use ASHRAE Standard 16 as the sole test standard
for cooling capacity. (AHRI, No. 11 at p. 2; AHRI, Framework Public
Meeting Transcript at p. 28) Goodman also encouraged DOE to adopt the
future revised version of ASHRAE Standard 16 as soon as it is
completed, and when this occurs, remove references to ASHRAE Standard
37 from the DOE test procedure. (Goodman, No. 13 at p. 2) AHRI
recommended that DOE specify either ASHRAE Standard 16 or ASHRAE 37 as
the sole method for conducting cooling capacity tests. (AHRI, No. 11 at
p. 2)
To investigate potential differences in results between the ASHRAE
Standard 16 and ASHRAE Standard 37 test methods, DOE conducted some
experimental testing on this issue using three PTAC units, one each
from three distinct manufacturers. DOE tested all three units at a
third-party testing lab under both ASHRAE Standard 16 and ASHRAE
Standard 37, and the results can be directly compared since both
standards allow for testing of the energy efficiency ratio (EER) at
peak-load conditions. The test results showed that differences in the
calculated EER between ASHRAE Standard 16 and ASHRAE Standard 37 ranged
from 0.4 to1.0 Btu/h-W, depending on the unit. These results do not
support a conclusion that the two methods of test generate consistent
results.
DOE understands that there is an ongoing process to revise ASHRAE
Standard 16 to incorporate psychrometric testing currently detailed in
ASHRAE Standard 37. Upon release of the updated standard, DOE may
consider updates to the DOE test procedure to reference the new
standard, as recommended by AHRI and Goodman.
To standardize the testing of PTACs and PTHPs, DOE is proposing to
require that only ASHRAE Standard 16 be used when conducting a cooling
mode test for PTACs and PTHPs. DOE seeks comment on its proposal to
designate
[[Page 14191]]
ASHRAE Standard 16 as the sole test method for determining cooling
efficiency. Specifically, DOE is interested in the test burden on
manufacturers of this designation, particularly given that all AHRI
certification program testing is conducted using ASHRAE Standard 16.
DOE also seeks information on whether there are PTAC or PTHP
manufacturers that conduct a significant number of tests using ASHRAE
Standard 37. This is identified as issue 5 in section V.E, ``Issues on
Which DOE Seeks Comment.''
E. Wall Sleeve Size and Filter Requirements for Testing
Wall Sleeve Size
The DOE test procedure provides limited guidance on the type of
wall sleeve that should be used during testing. Wall sleeves are used
in PTAC and PTHP testing to provide an outer case for the main
refrigeration components. In the field, the wall sleeves are often
installed in the building, and the cooling/heating assembly slides into
and out of this case. For standard size PTACs and PTHPs, the wall
sleeve measures 42 inches wide and 16 inches high; however, there is no
standardized depth.
Some manufacturers offer extended wall sleeves in a variety of
depths (up to 31 inches) that can be used with any of their standard
size PTACs or PTHPs. DOE believes that the use of varying test sleeve
depths can affect measured test results, due to the differences in
airflow and fan performance. DOE's test procedure, in section 4.3 of
ANSI/AHRI Standard 310/380, provides some limited guidance about the
wall sleeve that should be used during testing; it states that
``standard equipment shall be in place during all tests, unless
otherwise specified in the manufacturer's instructions to the user.''
However, there currently is no guidance for units where multiple test
sleeves might be acceptable.
DOE's survey of wall sleeve sizes on the market showed that the
most common wall sleeve depth is 14 inches. While DOE has no data
indicating the impact of testing with a maximum-depth sleeve as opposed
to a standard-depth sleeve, DOE expects that there may be an
incremental reduction in efficiency associated with use of a sleeve as
deep as 31 inches. The Working Group discussed the issue of varying
wall sleeve sizes and voted to adopt the position that units should be
tested using a standard 14 inch sleeve (Docket No. EERE-2013-BT-NOC-
0023, No. 53, pg. 17). Based on this information, DOE proposes to add a
provision to 10 CFR 431.96 to require testing using a wall sleeve with
a depth of 14 inches (or the wall sleeve option that is closest to 14
inches in depth that is available for the basic model being tested).
This is consistent with the recommendation by the Working Group.
Filter Requirements
The DOE test procedure provides limited guidance on the type of
filter that should be used during testing, and DOE has investigated the
issue of testing with standard filters versus high-efficiency filters.
PTACs or PTHPs generally ship with a filter to remove particulates from
the indoor airstream. There is currently no description in the DOE test
procedure of the type of filter to be used during testing. While some
PTACs and PTHPs only have one filter option, some PTACs and PTHPs are
shipped with either a standard filter or a high efficiency filter. A
high efficiency filter will impose more air flow restriction, which can
incrementally decrease air flow and the capacity or efficiency of the
unit.
DOE considered whether to specify a particular MERV filter
efficiency for use with the test, such as MERV-2 or MERV-3 levels of
filtration. However, DOE noted that the filter efficiencies offered in
PTACs and PTHPs are generally not specified using a standard metric.
Furthermore, some PTACs are sold with higher-efficiency ``standard-
option'' filters than others. Moreover, verification that the filter
used in the test complies with any such requirement would not be
possible without implementation of standardized requirements for
labeling of filters and reporting of filter efficiencies and/or
adopting a filter efficiency test as part of the test procedure, all of
which would impose additional burden. The Working Group was also aware
of this issue, and also discussed the issue of varying air filter
efficiency. The Working Group voted to adopt the position that units
should be tested ``as shipped'' with respect to selecting a filter
option (Docket No. EERE-2013-BT-NOC-0023, No. 53, pg. 16).
Consistent with the Working Group's recommendations, DOE proposes
to add a provision to 10 CFR 431.96 to require testing using the
standard or default filter option that is shipped with most units. For
those models that are not shipped with a filter, DOE proposes to
require the use of an off-the-shelf MERV-3 (minimum efficiency
reporting value) filter for testing.
DOE seeks comment on these proposals and whether there are any
PTACs or PTHPs that cannot be tested using a 14 inch deep wall sleeve.
DOE also seeks comment on whether a MERV-3 filter is appropriate for
testing PTACs and PTHPs that do not ship with filters. These have are
identified as issues 7 and 8 in section V.E, ``Issues on Which DOE
Seeks Comment.''
F. Barometric Pressure Correction
The DOE test procedure, in Section 6.1.3 of referenced ASHRAE
Standard 16, allows for adjustment of the capacity measurement based on
the tested barometric pressure: ``The capacity may be increased 0.8%
for each in. Hg below 29.92 in. Hg.'' Theoretically, air is less dense
at higher altitudes where the barometric pressure is lower. As a
result, air mass flow generated by fans and blowers is less at higher
altitudes, which may decrease the measured cooling capacity due to
reduced air flow over the coils. However, there are other competing
effects that may negate this decrease. DOE requested detailed test data
showing the relationship of capacity to barometric pressure in the
framework document. 78 FR 12252 (Feb. 22, 2013).
Goodman stated that it did not have data showing the relationship
between barometric pressure and cooling capacity but mentioned that
AHRI Standard 550-2011 (``Performance Rating of Water-Chilling and Heat
Pump Water-Heating Packages Using the Vapor Compression Cycle'') has a
normative appendix (Appendix F) that uses a barometric pressure
adjustment and that the ASHRAE Standard Project Committee is
considering adopting the AHRI 550 calculation in the revised ASHRAE
Standard 16. Goodman also commented that barometric pressure should be
used in performing capacity calculations for PTACs and PTHPs. (Goodman,
No. 13 at p. 2)
Because DOE has not received any data to support the removal of the
barometric pressure correction from the DOE test procedure, DOE is not
proposing to amend or remove this provision. DOE seeks comments or data
on the barometric pressure correction specifically used for PTACs and
PTHPs. This is identified as issue 4 in section V.E, ``Issues on Which
DOE Seeks Comment.''
G. Part-Load Efficiency Metric and Varying Ambient Conditions
The current DOE test procedure for PTACs and PTHPs measures cooling
and heating efficiency in terms of EER and coefficient of performance
(COP), respectively. Both of these metrics measure the efficiency of
the unit
[[Page 14192]]
running steadily at the maximum cooling or heating output settings.
The Appliance Standards Awareness Project (ASAP) raised the issue
that current efficiency metrics do not capture part load performance
and, for that reason, do not properly reflect the benefits of
technologies such as variable speed compressors that could save
significant energy in the field due to improvement in part load
efficiency. (ASAP, Framework Public Meeting Transcript at p. 35) ASAP
and the American Council for an Energy-Efficient Economy (ACEEE)
jointly encouraged DOE to develop a test procedure that captures part-
load efficiency in order to better represent the energy efficiency in
the field. They suggested that DOE adopt a metric similar to integrated
energy efficiency ratio (IEER), which measures efficiency at different
compressor load points (100%, 75%, 50%, and 25% of full capacity).\3\
(ASAP and ACEEE, No. 14 at p. 1) AHRI commented that PTACs and PTHPs
are generally operated at full load most of the time and that it is not
common practice in the field to operate the units at part load. (AHRI,
Framework Public Meeting Transcript at p. 36)
---------------------------------------------------------------------------
\3\ The IEER metric was developed by the American Society of
Heating, Refrigerating, and Air Conditioning Engineers (ASHRAE) for
Standard 90.1-2007. In Addenda from the 2008 Supplement to Standard
90.1-2007, ASHRAE replaced the integrated part load value (IPLV)
metric for commercial unitary air conditioners and commercial
unitary heat pumps with the IEER metric, effective January 1, 2010.
---------------------------------------------------------------------------
The CA IOUs stated that the DOE test procedure should require the
measurement and reporting of the performance of PTACs and PTHPs in a
variety of ambient conditions to represent varying climate zones. (CA
IOUs, No. 12 at p. 3) Southern Company Services (SCS) commented that if
DOE starts looking into part-load efficiency metrics for PTACs and
PTHPs, then DOE would need to consider climate issues in the metric,
which would be a complex issue. (SCS, Framework Public Meeting
Transcript at p. 37)
DOE is unaware of any data showing the time PTACs and PTHPs spend
operating in part-load conditions versus full-load conditions.
Likewise, DOE is unaware of any information that shows the amount of
time that PTACs and/or PTHPs spend cycling their compressors when
operating in conditions not requiring their full load. Likewise, DOE is
not aware of any data showing the amount of time that PTHPs with
defrost capabilities spend at different outdoor temperatures,
specifically at 17 [deg]F compared with that at 47 [deg]F. These data
would be needed to incorporate the lower temperatures into a part-load
metric, as noted by the CA IOUs. Such data would be necessary as inputs
to a part-load metric for PTACs and/or PTHPs.
DOE believes that the existing EER (full load) metric accurately
reflects equipment efficiency during the year. However, DOE recognizes
the importance of conducting the data collection outlined above to
establish whether a part load metric is needed and to provide the
necessary basis for developing such a metric. DOE will consider
gathering relevant data to assist in a future test procedure
rulemaking. However, DOE does not have sufficient information regarding
part-load operation to establish such a test procedure at this time.
The CA IOUs also stated that the heating mode test method should
include defrost mode operation and testing at both 47 [deg]F and 17
[deg]F to capture the effects of electric resistance heat. (CA IOUs,
No. 12 at p. 3)
DOE notes that ASHRAE Standard 58 includes a test of the defrost
operation for units that experience defrost during the standard rating
test at the specified test conditions. This test is not currently
included as part of the DOE test procedure. As stated above regarding
part-load metrics, DOE will consider such testing to assist in a future
test procedure rulemaking.
Ice Air, LLC (Ice Air) commented that DOE's current energy
conservation standards fail to account for the economic, environmental,
and energy impact of using electric heat in PTACs and PTHPs. It also
stated that there should be a standardized methodology for measuring
the impact of alternate heat sources (e.g., hydronic or gas heat), and
that the energy-efficiency impact of such heat sources should be
accounted for in the DOE test procedure. (Ice Air, No. 9 at p. 1)
DOE notes that the heating coefficient of performance calculated
using ANSI/AHRI Standard 310/380 does not include any energy consumed
by supplementary heating sources at times when low outdoor temperatures
require its use. It also does not include energy consumed by
supplementary hydronic or gas heating. To incorporate the energy
consumed by supplementary resistance heat would require changing the
metric to a seasonal metric, which would require knowledge of national
average heating load patterns for PTHPs as a function of ambient
temperature-information which DOE does not have at this time.
DOE is not proposing to adopt either a part-load or seasonal
efficiency metric for the cooling mode that considers part-load
performance, or a seasonal efficiency metric for the heating mode that
considers electric resistance heating for PTACs or PTHPs. DOE seeks
comments regarding this conclusion, including any information regarding
seasonal load patterns for PTACs and PTHPs in both cooling and heating
modes. This is identified as issue 6 in section V.E, ``Issues on Which
DOE Seeks Comment.''
H. Compliance Date of the Test Procedure Amendments
In amending a test procedure, EPCA directs DOE to determine to what
extent, if any, the test procedure would alter the measured energy
efficiency or measured energy use of a covered product. (42 U.S.C.
6314(a)(6)) If the amended test procedure alters the measured energy
efficiency or measured energy use, the Secretary must amend the
applicable energy conservation standard accordingly. (42 U.S.C.
6314(a)(6))
The proposed test procedure amendments for PTACs and PTHPS do not
contain changes that would materially alter the measured energy
efficiency of equipment. Rather, most of the proposed changes represent
clarifications that would improve the uniform application of the test
procedures for this equipment. Any change in the rated efficiency that
might be associated with these clarifications is expected to be de
minimis.
DOE's test procedure proposals being considered in this notice
would be effective 30 days after publication of the final rule in the
Federal Register. Consistent with 42 U.S.C. 6314(d), any
representations of energy consumption of PTACs and PTHPs must be based
on any final amended test procedures 360 days after the publication of
the test procedure final rule.
IV. Procedural Issues and Regulatory Review
A. Review Under Executive Order 12866
The Office of Management and Budget (OMB) has determined that test
procedure rulemakings do not constitute ``significant regulatory
actions'' under section 3(f) of Executive Order 12866, Regulatory
Planning and Review, 58 FR 51735 (Oct. 4, 1993). Accordingly, this
action was not subject to review under the Executive Order by the
Office of Information and Regulatory Affairs (OIRA) in the Office of
Management and Budget.
[[Page 14193]]
B. Review Under the Regulatory Flexibility Act
The Regulatory Flexibility Act (5 U.S.C. 601 et seq.) requires
preparation of an initial regulatory flexibility analysis (IFRA) for
any rule that by law must be proposed for public comment, unless the
agency certifies that the rule, if promulgated, will not have a
significant economic impact on a substantial number of small entities.
As required by Executive Order 13272, ``Proper Consideration of Small
Entities in Agency Rulemaking,'' 67 FR 53461 (August 16, 2002), DOE
published procedures and policies on February 19, 2003, to ensure that
the potential impacts of its rules on small entities are properly
considered during the DOE rulemaking process. 68 FR 7990. DOE has made
its procedures and policies available on the Office of the General
Counsel's Web site: http://energy.gov/gc/office-general-counsel.
DOE reviewed today's proposed rule under the provisions of the
Regulatory Flexibility Act and the procedures and policies published on
February 19, 2003. This proposed rule prescribes test procedures that
will be used to test compliance with energy conservation standards for
the products that are the subject of this rulemaking. DOE has
tentatively concluded that the proposed rule would not have a
significant impact on a substantial number of small entities.
The Small Business Administration (SBA) considers an entity to be a
small business if, together with its affiliates, it employs less than a
threshold number of workers specified in 13 CFR part 121, which relies
on size standards and codes established by the North American Industry
Classification System (NAICS). The threshold number for NAICS
classification for 333415, which applies to air conditioning and warm
air heating equipment and commercial and industrial refrigeration
equipment, is 750. Searches of the SBA Web site \4\ to identify
manufacturers within these NAICS codes that manufacture PTACs and/or
PTHPs did not identify any small entities that could be affected by
this test procedure modification.
---------------------------------------------------------------------------
\4\ A searchable database of certified small businesses is
available online at: http://dsbs.sba.gov/dsbs/search/dsp_dsbs.cfm.
---------------------------------------------------------------------------
DOE expects the impact of the proposed rule to be minimal. The
proposed rule would amend DOE's test procedures to specify an optional
break-in period, explicitly require that wall sleeves be sealed to
prevent air leakage, allow for the pre-filling of the condensate drain
pan, require that the cooling mode be tested using only ASHRAE Standard
16, and require testing with 14-inch deep wall sleeves and the filter
option most representative of a typical installation. These tests can
be conducted in the same facilities used for the current energy testing
of these products and do not require testing in addition to what is
currently required. The break-in period is optional and may result in
improved energy efficiency of the unit; the break-in is also generally
conducted outside of the balanced-ambient calorimeter facility. DOE
expects that manufacturers will require minimal time to plug in and run
the PTACs and PTHPs, and will only incur the additional time for the
break-in step if it is beneficial to testing. In this case, the cost
will be minimal due to the nature of the testing and the fact that it
is not conducted within the facility.
Material costs are expected to be negligible, as air sealing the
wall sleeves can be accomplished with typically available lab
materials, and there are no additional costs from specifying a
particular wall sleeve and/or filter that typically comes with the
unit. In addition, pre-filling of the condensate pan is expected to
reduce test time by 2-4 hours, which would reduce testing costs by
approximately $375-750 per test. DOE also believes that most
manufacturers are already using ASHRAE Standard 16 because all AHRI
testing is conducted using this method. Thus, such requirements for
equipment and time to conduct tests (if necessary to recertify using
ASHRAE Standard 16) would not be expected to impose a significant
economic impact.
For these reasons, DOE certifies that the proposed rule would not
have a significant economic impact on a substantial number of small
entities. Accordingly, DOE has not prepared a regulatory flexibility
analysis for this rulemaking. DOE will transmit the certification and
supporting statement of factual basis to the Chief Counsel for Advocacy
of the SBA for review under 5 U.S.C. 605(b).
C. Review Under the Paperwork Reduction Act of 1995
Manufacturers of packaged terminal air conditioners and packaged
terminal heat pumps must certify to DOE that their equipment complies
with any applicable energy conservation standards. In certifying
compliance, manufacturers must test their equipment according to the
DOE test procedures for packaged terminal air conditioners and packaged
terminal heat pumps, including any amendments adopted for those test
procedures. DOE has established regulations for the certification and
recordkeeping requirements for all covered consumer products and
commercial equipment, including packaged terminal air conditioners and
packaged terminal heat pumps. 76 FR 12422 (Mar. 7, 2011). The
collection-of-information requirement for the certification and
recordkeeping is subject to review and approval by OMB under the
Paperwork Reduction Act (PRA).
In the Certification of Commercial Equipment NOPR issued on
February 7, 2014, DOE proposed to revise and expand its existing
regulations governing compliance certification for commercial HVAC, WH,
and CRE equipment covered by EPCA. 79 FR 8886. Requirements for PTAC
and PTHP manufacturers were included in the Certification of Commercial
Equipment NOPR, and DOE sought comment on this proposed expansion of
the existing information collection. 79 FR 8886. In today's NOPR, DOE
is proposing to include the break-in period and the wall sleeve
dimensions under the current certification requirements listed in 10
CFR 429.43. DOE does not believe that these additions to the
certification requirements constitute a significant additional burden
upon respondents, as they require the addition of two additional pieces
of information on the existing certification report. DOE believes that
the Certification of Commercial Equipment NOPR provides an accurate
estimate of the existing burden on respondents. 79 FR 8886.
Notwithstanding any other provision of the law, no person is
required to respond to, nor shall any person be subject to a penalty
for failure to comply with, a collection of information subject to the
requirements of the PRA, unless that collection of information displays
a currently valid OMB Control Number.
D. Review Under the National Environmental Policy Act of 1969
In this proposed rule, DOE proposes test procedure amendments that
it expects will be used to develop and implement future energy
conservation standards for packaged terminal air conditioners and
packaged terminal heat pumps. DOE has determined that this rule falls
into a class of actions that are categorically excluded from review
under the National Environmental Policy Act of 1969 (42 U.S.C. 4321 et
seq.) and DOE's implementing regulations at 10 CFR part 1021.
Specifically, this proposed rule would amend the existing test
procedures without affecting the amount, quality or distribution of
energy usage, and, therefore, would not result in any environmental
impacts. Thus, this
[[Page 14194]]
rulemaking is covered by Categorical Exclusion A5 under 10 CFR part
1021, subpart D, which applies to any rulemaking that interprets or
amends an existing rule without changing the environmental effect of
that rule. Accordingly, neither an environmental assessment nor an
environmental impact statement is required.
E. Review Under Executive Order 13132
Executive Order 13132, ``Federalism,'' 64 FR 43255 (August 4, 1999)
imposes certain requirements on agencies formulating and implementing
policies or regulations that preempt State law or that have Federalism
implications. The Executive Order requires agencies to examine the
constitutional and statutory authority supporting any action that would
limit the policymaking discretion of the States and to carefully assess
the necessity for such actions. The Executive Order also requires
agencies to have an accountable process to ensure meaningful and timely
input by State and local officials in the development of regulatory
policies that have Federalism implications. On March 14, 2000, DOE
published a statement of policy describing the intergovernmental
consultation process it will follow in the development of such
regulations. 65 FR 13735. DOE has examined this proposed rule and has
determined that it would not have a substantial direct effect on the
States, on the relationship between the national government and the
States, or on the distribution of power and responsibilities among the
various levels of government. EPCA governs and prescribes Federal
preemption of State regulations as to energy conservation for the
equipment that is the subject of today's proposed rule. States can
petition DOE for exemption from such preemption to the extent, and
based on criteria, set forth in EPCA. (42 U.S.C. 6297(d)) No further
action is required by Executive Order 13132.
F. Review Under Executive Order 12988
Regarding the review of existing regulations and the promulgation
of new regulations, section 3(a) of Executive Order 12988, ``Civil
Justice Reform,'' 61 FR 4729 (Feb. 7, 1996), imposes on Federal
agencies the general duty to adhere to the following requirements: (1)
Eliminate drafting errors and ambiguity; (2) write regulations to
minimize litigation; (3) provide a clear legal standard for affected
conduct rather than a general standard; and (4) promote simplification
and burden reduction. Section 3(b) of Executive Order 12988
specifically requires that Executive agencies make every reasonable
effort to ensure that the regulation: (1) Clearly specifies the
preemptive effect, if any; (2) clearly specifies any effect on existing
Federal law or regulation; (3) provides a clear legal standard for
affected conduct while promoting simplification and burden reduction;
(4) specifies the retroactive effect, if any; (5) adequately defines
key terms; and (6) addresses other important issues affecting clarity
and general draftsmanship under any guidelines issued by the Attorney
General. Section 3(c) of Executive Order 12988 requires Executive
agencies to review regulations in light of applicable standards in
sections 3(a) and 3(b) to determine whether they are met or it is
unreasonable to meet one or more of them. DOE has completed the
required review and determined that, to the extent permitted by law,
the proposed rule meets the relevant standards of Executive Order
12988.
G. Review Under the Unfunded Mandates Reform Act of 1995
Title II of the Unfunded Mandates Reform Act of 1995 (UMRA)
requires each Federal agency to assess the effects of Federal
regulatory actions on State, local, and Tribal governments and the
private sector. Public Law 104-4, sec. 201 (codified at 2 U.S.C. 1531).
For a proposed regulatory action likely to result in a rule that may
cause the expenditure by State, local, and Tribal governments, in the
aggregate, or by the private sector of $100 million or more in any one
year (adjusted annually for inflation), section 202 of UMRA requires a
Federal agency to publish a written statement that estimates the
resulting costs, benefits, and other effects on the national economy.
(2 U.S.C. 1532(a), (b)) The UMRA also requires a Federal agency to
develop an effective process to permit timely input by elected officers
of State, local, and Tribal governments on a proposed ``significant
intergovernmental mandate,'' and requires an agency plan for giving
notice and opportunity for timely input to potentially affected small
governments before establishing any requirements that might
significantly or uniquely affect small governments. On March 18, 1997,
DOE published a statement of policy on its process for
intergovernmental consultation under UMRA. 62 FR 12820; also available
at http://energy.gov/gc/office-general-counsel. DOE examined today's
proposed rule according to UMRA and its statement of policy and
determined that the rule contains neither an intergovernmental mandate,
nor a mandate that may result in the expenditure of $100 million or
more in any year, so these requirements do not apply.
H. Review Under the Treasury and General Government Appropriations Act,
1999
Section 654 of the Treasury and General Government Appropriations
Act, 1999 (Pub. L. 105-277) requires Federal agencies to issue a Family
Policymaking Assessment for any rule that may affect family well-being.
This rule would not have any impact on the autonomy or integrity of the
family as an institution. Accordingly, DOE has concluded that it is not
necessary to prepare a Family Policymaking Assessment.
I. Review Under Executive Order 12630
DOE has determined, under Executive Order 12630, ``Governmental
Actions and Interference with Constitutionally Protected Property
Rights'' 53 FR 8859 (March 18, 1988), that this regulation would not
result in any takings that might require compensation under the Fifth
Amendment to the U.S. Constitution.
J. Review Under Treasury and General Government Appropriations Act,
2001
Section 515 of the Treasury and General Government Appropriations
Act, 2001 (44 U.S.C. 3516 note) provides for agencies to review most
disseminations of information to the public under guidelines
established by each agency pursuant to general guidelines issued by
OMB. OMB's guidelines were published at 67 FR 8452 (Feb. 22, 2002), and
DOE's guidelines were published at 67 FR 62446 (Oct. 7, 2002). DOE has
reviewed today's proposed rule under the OMB and DOE guidelines and has
concluded that it is consistent with applicable policies in those
guidelines.
K. Review Under Executive Order 13211
Executive Order 13211, ``Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use,'' 66 FR 28355
(May 22, 2001), requires Federal agencies to prepare and submit to OMB,
a Statement of Energy Effects for any proposed significant energy
action. A ``significant energy action'' is defined as any action by an
agency that promulgated or is expected to lead to promulgation of a
final rule, and that: (1) Is a significant regulatory action under
Executive Order 12866, or any successor order; and (2) is likely to
have a significant adverse effect on the supply, distribution, or use
of energy; or (3) is designated by the Administrator of OIRA as a
significant energy action. For
[[Page 14195]]
any proposed significant energy action, the agency must give a detailed
statement of any adverse effects on energy supply, distribution, or use
should the proposal be implemented, and of reasonable alternatives to
the action and their expected benefits on energy supply, distribution,
and use.
Today's regulatory action to amend the test procedure for measuring
the energy efficiency of packaged terminal air conditioners and
packaged terminal heat pumps is not a significant regulatory action
under Executive Order 12866. Moreover, it would not have a significant
adverse effect on the supply, distribution, or use of energy, nor has
it been designated as a significant energy action by the Administrator
of OIRA. Therefore, it is not a significant energy action, and,
accordingly, DOE has not prepared a Statement of Energy Effects.
L. Review Under Section 32 of the Federal Energy Administration Act of
1974
Under section 301 of the Department of Energy Organization Act
(Pub. L. 95-91; 42 U.S.C. 7101), DOE must comply with section 32 of the
Federal Energy Administration Act of 1974, as amended by the Federal
Energy Administration Authorization Act of 1977. (15 U.S.C. 788; FEAA)
Section 32 essentially provides in relevant part that, where a proposed
rule authorizes or requires use of commercial standards, the notice of
proposed rulemaking must inform the public of the use and background of
such standards. In addition, section 32(c) requires DOE to consult with
the Attorney General and the Chairman of the Federal Trade Commission
(FTC) concerning the impact of the commercial or industry standards on
competition.
The proposed rule incorporates testing methods contained in the
following commercial standards: ANSI/AHRI Standard 310/380-2004 and
ASHRAE Standard 16-1983 (RA 2009). The Department has evaluated these
standards and is unable to conclude whether they fully comply with the
requirements of section 32(b) of the FEAA, (i.e., that they were
developed in a manner that fully provides for public participation,
comment, and review). DOE will consult with the Attorney General and
the Chairman of the FTC concerning the impact of these test procedures
on competition, prior to prescribing a final rule.

DOE will conduct it in accordance with section 336 of EPCA (42 U.S.C.
6306). A court reporter will be present to record the proceedings and
prepare a transcript. DOE reserves the right to schedule the order of
presentations and to establish the procedures governing the conduct of
the public meeting. After the public meeting and until the end of the
comment period, interested parties may submit further comments on the
proceedings and any aspect of the rulemaking.
The public meeting will be conducted in an informal, conference
style. DOE will present summaries of comments received before the
public meeting, allow time for prepared general statements by
participants, and encourage all interested parties to share their views
on issues affecting this rulemaking. Each participant will be allowed
to make a general statement (within time limits determined by DOE),
before the discussion of specific topics. DOE will permit, as time
permits, other participants to comment briefly on any general
statements.
At the end of all prepared statements on a topic, DOE will permit
participants to clarify their statements briefly and comment on
statements made by others. Participants should be prepared to answer
questions by DOE and by other participants concerning these issues. DOE
representatives may also ask questions of participants concerning other
matters relevant to this rulemaking. The official conducting the public
meeting will accept additional comments or questions from those
attending, as time permits. The presiding official will announce any
further procedural rules or modification of the above procedures that
may be needed for the proper conduct of the public meeting.
A transcript of the public meeting will be included in the docket,
which can be viewed as described in the Docket section at the beginning
of this notice. In addition, any person may buy a copy of the
transcript from the transcribing reporter.
D. Submission of Comments
DOE will accept comments, data, and information regarding this
proposed rule before or after the public meeting, but no later than the

E. Issues on Which DOE Seeks Comment
Although DOE welcomes comments on any aspect of this proposal, DOE
is particularly interested in receiving comments and views of
interested parties concerning the following issues:
1. DOE seeks comment on its proposal to add an optional break-in
period to the test procedure (up to 20 hours) for PTACs and PTHPs, and
whether the duration of the proposed break-in period is appropriate. If
commenters support longer break-in times, DOE also requests data
showing that break-in periods longer than 20 hours make a significant
impact on efficiency measurements for this equipment type.
2. DOE seeks comments on the sealing of PTAC and PTHP wall sleeves
to the test facility dividing wall, including whether the type or
method of sealing should be specified in the test procedure, and
whether a test has been developed that could be performed to verify
that adequate elimination of air leakage has been achieved.
3. DOE seeks comments on its proposal to permit the pre-filling of
the condensate drain pan, including whether the mineral content of the
water or temperature of the water used would affect the measurement
and/or whether these data should be recorded and documented as part of
the test records underlying certification.
4. DOE seeks comments on its proposal to require testing using 14-
inch deep wall sleeves and standard filters. DOE is also interested in
whether there are any PTACs or PTHPs that cannot be tested with a 14-
inch deep wall sleeve.
5. DOE also seeks comment on its proposal to require the use of
MERV-3 filter for testing PTACs and PTHPs that do not ship with
filters.
6. DOE seeks comments or data on the need for a barometric pressure
correction for PTACs and PTHPs.
7. DOE seeks comments on its proposal to designate ASHRAE Standard
16 as the sole test method for measuring cooling efficiency for PTACs
and PTHPs. Specifically, DOE is interested in the test burden on
manufacturers resulting from this proposed requirement, and whether
there are PTAC or PTHP manufacturers that currently conduct a
significant number of tests using ASHRAE Standard 37.
8. DOE seeks comments on its proposal not to develop seasonal
efficiency metrics that would evaluate part-load operation of PTACs and
PTHPs or the impact of electric resistance heating in low ambient
temperatures for PTHPs. DOE also seeks any information regarding
seasonal load patterns for PTACs and PTHPs in both cooling and heating
modes.

(3) Wall sleeves. For packaged terminal air conditioners and
packaged terminal heat pumps, the unit must be installed in a wall
sleeve with a 14 inch depth if available. If a 14 inch deep wall sleeve
is not available, use the available wall sleeve option closest to 14
inches in depth. The area(s) between the wall sleeve and the insulated
partition between the indoor and outdoor rooms must be sealed to
eliminate all air leakage through this area.
(4) Optional pre-filling of the condensate drain pan. For packaged
terminal air conditioners and packaged terminal heat pumps, test
facilities may add water to the condensate drain pan of the equipment
under test (until the water drains out due to overflow devices or until
the pan is full) prior to conducting the test method specified by AHRI
310/380-2004 (incorporated by reference, see Sec. 431.95). No specific
level of water mineral content or water temperature is required for the
water added to the condensate drain pan.
(5) Test Method for Standard Cooling Ratings. For packaged terminal
air conditioners and packaged terminal heat pumps, the ANSI/ASHRAE test
[[Page 14199]]
method used in tests shall be ANSI/ASHRAE 16 (incorporated by
reference, see Sec. 431.95).
(6) Filter selection. For packaged terminal air conditioners and
packaged terminal heat pumps, the indoor filter used during testing
shall be the standard or default filter option shipped with the model
with the model. If a particular model is shipped without a filter, the
unit must be tested with a level MERV-3 filter.
