III. Application for Interim Waiver
IV. Alternate Test Procedure
V. Summary and Request for Comments
sroberts on PROD1PC70 with NOTICES
I. Background and Authority
Title III of the Energy Policy and
Conservation Act (EPCA) sets forth a
variety of provisions concerning energy
efficiency. Part C of Title III (42 U.S.C.
6311–6317) provides for an energy
efficiency program entitled ‘‘Certain
Industrial Equipment,’’ and includes
commercial air conditioning equipment,
packaged boilers, water heaters, and
other types of commercial equipment.
Today’s notice involves commercial
equipment under Part C, which
specifically provides for definitions, test
procedures, labeling provisions, energy
conservation standards, and the
authority to require information and
reports from manufacturers. With
respect to test procedures, Part C
generally authorizes the Secretary of
Energy to prescribe test procedures that
are reasonably designed to produce
results which reflect energy efficiency,
energy use and estimated operating
costs, and that are not unduly
burdensome to conduct. (42 U.S.C.
6314(a)(2)).
For commercial package air
conditioning and heating equipment,
EPCA provides that the test procedures
shall be those generally accepted
industry testing procedures or rating
procedures developed or recognized by
the Air-Conditioning and Refrigeration
Institute (ARI) or by the American
Society of Heating, Refrigerating and Air
Conditioning Engineers (ASHRAE), as
referenced in ASHRAE/IES Standard
90.1 and in effect on June 30, 1992. (42
U.S.C. 6314(a)(4)(A)) This section also
provides for the Secretary of Energy to
amend the test procedure for a product
if the industry test procedure is
amended, unless the Secretary
determines that such a modified test
procedure does not meet the statutory
criteria. (42 U.S.C. 6314(a)(4)(B)) On
October 21, 2004, DOE published a
direct final rule, effective December 20,
2004, adopting ARI Standard 210/240–
2003 for small commercial package air
conditioning and heating equipment
VerDate Aug<31>2005
18:52 Apr 19, 2007
Jkt 211001
with capacities < 65,000 Btu/h and ARI
Standard 340/360–2000 for large
commercial package air conditioning
and heating equipment with capacities
≥ 135,000 Btu/h and < 240,000 Btu/h
and small commercial package air
conditioning and heating equipment
with capacities ≥ 65,000 Btu/h and <
135,000 Btu/h. 69 FR 61962, October 21,
2004. According to Cascade, both ARI
Standard 340/360–2000 and ARI
Standard 210/240–2003 are applicable
to Cascade’s Cascade Energy Saver
(CES) products. However, Cascade only
seeks a waiver from ARI Standard 210/
240–2003.
DOE’s regulations set forth under 10
CFR 431.401 contain provisions
allowing a person to seek a waiver from
the test procedure requirements for
commercial equipment. The waiver
provisions allow the Assistant Secretary
for Energy Efficiency and Renewable
Energy (hereafter ‘‘Assistant Secretary’’)
to temporarily waive test procedures for
a particular basic model when a
petitioner shows that the basic model
contains one or more design
characteristics which either prevent
testing according to the prescribed test
procedures, or when the prescribed test
procedures may evaluate the basic
model in a manner so unrepresentative
of its true energy consumption as to
provide materially inaccurate
comparative data. 10 CFR 431.401(a)(1).
The Assistant Secretary may grant the
waiver subject to conditions, including
adherence to alternate test procedures.
10 CFR 431.401(f)(4). Petitioners are to
include in their petition any alternate
test procedures known to evaluate the
basic model in a manner representative
of its energy consumption. 10 CFR
431.401(b)(1)(iii). Waivers generally
remain in effect until final test
procedure amendments become
effective, thereby resolving the problem
that is the subject of the waiver. 10 CFR
431.401(g).
The waiver process also allows the
Assistant Secretary to grant an interim
waiver from test procedure
requirements to manufacturers who
have petitioned DOE for a waiver of
such prescribed test procedures. 10 CFR
431.401(a)(2). An interim waiver
remains in effect for a period of 180
days or until DOE issues its
determination on the petition for
waiver, whichever is sooner, and may
be extended for an additional 180 days,
if necessary. 10 CFR 431.401(e)(4).
II. Petition for Waiver
On July 22, 2005, Cascade filed the
Cascade Petition for Waiver and its
Application for an Interim Waiver from
the test procedures applicable to
PO 00000
Frm 00017
Fmt 4703
Sfmt 4703
commercial package air conditioning
and heating equipment. On May 26,
2006, Cascade filed an amended Petition
for Waiver listing all the basic models
for which Cascade seeks a waiver. In
particular, Cascade requested a waiver
from the commercial test procedures
contained in ARI Standard 210/240–
2003 for the system combinations listed
in Table 1, attached to its amended
Petition.
Cascade seeks a waiver from the test
procedures in ARI Standard 210/240–
2003 and asserts that the design
characteristics of the CES systems
prevent testing according to these
prescribed test procedures. In particular,
Cascade states that the CES indoor-coil
blower models have more than one
blower per coil and up to and as many
as eight blowers that operate
independently. Cascade claims that its
products do not conform to the test
procedures in ARI Standard 210/240–
2003, because these test procedures are
based on a system with only one indoorcoil blower.
Cascade asserts that with slight
modifications to ARI 210/240
procedures, CES units can be tested and
that such testing can provide
measurements to satisfactorily
determine the Seasonal Energy
Efficiency Ratio (SEER) and the Heating
Seasonal Performance Factor (HSPF).
Cascade included in its petition sample
SEER calculations, sample test
procedures used to derive the SEER
calculations, and sample test data. The
testing, contracted by Cascade to Texas
A&M University Energy Services
Laboratory (hereafter ‘‘TAMU–ESL’’),
provides data on a system with two 2.5ton Amana RHF 030 heat pump units of
SEER 12 connected to a dual-circuit
evaporator coil, followed by a plenum
housing 8 blowers operated by a control
system. Using a test procedure based on
ARI 210/240, TAMU–ESL calculated a
SEER value of 18.1 and an HSPF of 9.5.
Details of the testing are provided in the
Cascade Petition, published in full,
below.
III. Application for Interim Waiver
Cascade also requested immediate
relief through its Application for Interim
Waiver to avert undue economic
hardship. According to DOE regulations,
an interim waiver may be granted if it
is determined that the applicant will
experience economic hardship if the
application for interim waiver is denied,
if it appears likely that the petition for
waiver will be granted, and/or the
Assistant Secretary determines that it
would be desirable for public policy
reasons to grant immediate relief
E:\FR\FM\20APN1.SGM
20APN1
Federal Register / Vol. 72, No. 76 / Friday, April 20, 2007 / Notices
sroberts on PROD1PC70 with NOTICES
pending a determination of the petition
for waiver. 10 CFR 431.401(e)(3).
Cascade’s Application for Interim
Waiver does not provide sufficient
information to evaluate what, if any,
economic impact or competitive
disadvantage Cascade will likely
experience absent a favorable
determination on its application. It also
does not provide sufficient information
to determine if there are public policy
reasons to grant immediate relief.
Furthermore, DOE has never granted a
previous waiver for a similar product
design. Thus, the likelihood of granting
the waiver is unclear until further
information and comment is provided.
Therefore, Cascade’s Application for
an Interim Waiver from the DOE test
procedure for its CES products is
denied. Hence, it is ordered that: The
Application for Interim Waiver filed by
Cascade is hereby denied for Cascade’s
CES air conditioners and central air
conditioning heat pumps.
This denial of Cascade’s Application
for Interim Waiver is based upon the
presumed validity of statements and
allegations submitted by the company.
This denial of Interim Waiver may be
modified if DOE receives information
that justifies granting an Interim Waiver.
IV. Alternate Test Procedure
DOE will make its judgment on the
Cascade Petition after the period for
public comment ends. However, should
DOE grant Cascade a waiver from the
applicable test procedures, DOE would
likely prescribe an alternate test
procedure. Manufacturers face
restrictions with respect to making
representations about the energy
consumption and energy consumption
costs of products covered by EPCA. (42
U.S.C. 6314(d)) Consistent
representations are important for
manufacturers to make claims about the
energy efficiency of their products. For
example, they are necessary to
determine compliance with state and
local energy codes and regulatory
requirements, and can provide valuable
consumer purchasing information.
Therefore, DOE is considering an
alternate test procedure for Cascade.
DOE is publishing the proposed
alternate test procedure in this notice to
account for the potential need for an
alternate test procedure and to allow the
public to comment on a proposed
alternate test procedure.
Cascade included a description of an
alternate test procedure and test data for
a sample system in its Petition. DOE is
considering prescribing an alternate test
procedure that takes into account the
information Cascade provided in the
petition. In particular, the proposed
VerDate Aug<31>2005
18:52 Apr 19, 2007
Jkt 211001
alternate test procedure would require
Cascade to test units according to ARI
Standard 210/240–2003, but permit
Cascade to use alternate requirements
when testing systems that have multiple
fans per indoor coil.1 Cascade may test
systems with multiple indoor fans that
jointly provide the total indoor-coil
airflow rate required for the capacity
being tested, however, Cascade would
be required to adhere to the airflow
requirement of section 6.1.3.3 of ARI
Standard 210/240–2003, which sets an
upper limit on indoor-coil airflow
according to system capacity.2 During
testing, the individual indoor fans
would each deliver an equal portion of
the total required airflow.
DOE generally agrees with TAMU–
ESL’s testing and analysis of a system
with a CES 5-ton, 8-zone unit connected
to an Amana RHF030 heat pump with
a SEER of 12–14. As each Amana
RHF030 heat pump uses a single-speed
compressor, DOE agrees with TAMU–
ESL’s choice to treat the system as a
two-speed blower with a two-stage
compressor and test the system
according to A2.2.2 and A2.1.3.
Furthermore, DOE agrees with TAMU–
ESL’s decision to ensure a total indoorcoil airflow rate of around 2,000 cfm
with eight blowers providing 250 cfm
each, when operating the system at a
full capacity. For low-speed conditions,
TAMU–ESL operated the system at a
2.5-ton capacity and ensured a total
indoor-coil airflow rate of around 1,000
cfm, with four blowers providing 250
cfm each.
However, it is not clear why TAMU–
ESL conducted Test C for full load
operation only, though section A3.1.3
indicates that if one chooses to perform
Test C, the system must be tested at lowspeed. Furthermore, for certification,
testing conditions must fall within the
applicable tolerances provided in ARI
210/240–2003. Finally, while DOE
generally approves of the TAMU–ESL
method to test a CES multi-blower unit
paired with two Amana RHF030 heat
pumps, DOE would expect Cascade to
test its units according to those
appropriate tests, procedures and
conditions generally stated in ARI 210/
240–2003. For example, testing of a CES
1 For example, according to a 450 cfm/ton
requirement, a 5 ton unit would be permitted to
have an airflow rate of 2,250 cfm or lower. If that
system were to operate at 2,000 cfm and have 8
fans, each fan would blow 250 cfm. In addition, if
that same system were to operate at partial load
with 2.5 tons of capacity, the tester could operate
4 fans with each fan blowing 250 cfm.
2 For example, section 6.1.3.3 requires equipment
with indoor fans intended for use with field
installed duct systems to be rated at the indoor-coil
airflow rate of equal to or less than 37.5 SCFM per
1,000 Btu/h of rated capacity.
PO 00000
Frm 00018
Fmt 4703
Sfmt 4703
19893
unit paired to a variable-speed
compressor should follow the
procedures and requirements described
for a system with a variable-speed
compressor in A2.1.6.
Given consideration of the
information provided to DOE in the
Cascade Petition, DOE is considering
the following alternate test procedure:
Alternate test procedure. Cascade
shall be required to test the products
covered under this Waiver according to
the prescribed tests, conditions, and
procedures referenced in ARI Standard
210/240–2003, except that Cascade shall
be permitted to test systems with indoor
units that have multiple fans. As such,
Cascade shall be required to meet the
usual indoor-coil airflow rate
requirements of ARI Standard 210/240–
2003, section 6.1.3.3. However, tested
units may run multiple indoor-coil fans
which collectively meet the required
indoor-coil airflow rates per capacity.
To determine the level at which to
operate the indoor fans during testing,
Cascade may divide the total indoor-coil
airflow rate at full load, by the number
of indoor fans in the tested system.
During testing, Cascade shall run the
indoor fans at this level, and may decide
how many indoor fans to operate by
dividing the total indoor-coil airflow
required at the capacity being tested by
the indoor fan level, as determined
above. Cascade may make
representations of the CES products
covered in this Waiver, consistent with
the provisions outlined in this alternate
test procedure.
V. Summary and Request for Comments
Today’s notice announces the Cascade
Petition for Waiver and denies
Cascade’s Application for Interim
Waiver from the test procedures
applicable to Cascade’s CES air
conditioner and heat pump units. DOE
is publishing the Cascade Petition for
Waiver in its entirety. The Cascade
Petition contains no confidential
information. Furthermore, today’s
notice includes an alternate test
procedure that the DOE is considering
including in the subsequent Decision
and Order, should DOE decide to grant
Cascade a Waiver.
DOE is interested in receiving
comments on all aspects of this notice.
DOE is particularly interested in
receiving comments and views of
interested parties concerning whether to
grant the Cascade Petition and regarding
the proposed alternate test procedure.
Specifically, DOE would like to receive
comment on the following questions:
• Does this alternate test procedure
adequately specify how to handle
E:\FR\FM\20APN1.SGM
20APN1
19894
Federal Register / Vol. 72, No. 76 / Friday, April 20, 2007 / Notices
airflows when testing a system with
multiple blowers?
• In the proposed alternate test
procedure, fans are to run at a set cfm
per fan throughout a test. Is this
appropriate or should DOE allow fans to
run at different cfm’s throughout a test
while still meeting the required overall
indoor-coil airflow rate according to
capacity?
• Cascade states that the current test
procedure is not specific about the
method of configuring a dual-circuited
evaporator coil to blowers. However,
Cascade does not propose specific
language. Does the alternate test
procedure proposed in this notice need
to specifically address configurations of
dual-evaporator coils and coil-blowers?
• DOE is interested in receiving
general comments on possible
modifications to any test procedures or
alternative rating methods that DOE
could use to fairly represent the energy
efficiency of Cascade’s CES products.
Any person submitting written
comments must also send a copy of
such comments to the Petitioner, whose
contact information is cited above. 10
CFR 431.201(d)(2).

that are applicable to the CES are the
ARI 210/240 and ARI 340/360.
ARI 210/240 is the standard that
certifies the performance of units that
are 65,000 Btu/hr or less. Currently, this
standard requires that a split system
heat pump meet a minimum SEER of 10.
The standard also stipulates that it meet
the maximum standard airflow rate of
37.5 CFM/1000Btu/hr. This CFM is
assumed to be applicable to the indoor
unit that has only one blower-motor.
The CES unit does not fit this model in

Davis under the supervision of Dr.
Dennis O’Neal, Dean of Mechanical
Engineering, Texas A&M University.
The following results show that under
ARI 210/240 conditions, connecting the
CES 5ton-8 zone unit to an Amana
RHF030 heat pump with an SEER of 12–
14 (dependant on the indoor blower-coil
for the rating) produced an SEER value
based on the calculations of 18.1 and an
HSPF of 9.5. This is a 29% savings on
cooling Seasonal energy efficiency Ratio
and a 19% increase over the heating
seasonal efficiency ratio.

Specific Requirements Sought To Be
Waived
Cascade requests a waiver by this
petition from the procedures of ARI210/
240 for models that are 65000Btu/h and
smaller because the Cascade
Manufacturing indoor blower coil
models have more than one blower per
coil and up to and as many as eight
blowers. Thus, it does not conform to
the test procedures of ARI 210/240,
which are based solely on one single
indoor-coil blower. We have proven
with laboratory tests that an enhanced
multi-blower fan coil is efficient and
that by slight modifications to the
current ARI 210/240 procedures,
Cascade Energy Saver units can be
tested and the results will show that the
SEER and HSPF are easily measurable.
Pursuant to the purchase of the CES,
Cascade seeks to be a viable and
profitable business concern and therefor
desires to implement its business plan
for manufacturing and distribution of
mass quantities of the CES units in the
various models and sizes to the general
public within the United States. To
effectuate the manufacturing and
distribution, Cascade has entered into
certain agreements with United Chester
Industries, Inc. dba United Mechanical,
Inc., an existing mechanical contractor
with manufacturing and distribution
capabilities.
Cascade seeks immediate relief
through this waiver to avert undo
economic hardship.
Discussion in Details for the Requested
Waiver
Concerning ARI 210/240
1. The ARI 210/240 test procedure
does not take into account indoor
blower coils with more than one indoor
blower and motor. The Cascade Energy
Saver indoor coil-blower is thus a
deviation from the ARI 210/240 model.
This design is what Cascade believes

will be product to fill a market niche
and that the consumer with find huge
energy saving benefits.
Cascade contracted with TAMU–ESL
to perform the ARI 210/240 testing
comprised of two operating conditions,
namely with 2 variations/combinations
of indoor blowers and outdoor heat
pumps, in order to demonstrate that the
efficiencies are within the acceptable
values of the NAECA, namely, SEER,
COP, HSPF.
2. In addition to the data, the
assumptions, the test conditions, the
procedures followed by TAMU–ESL are
all included in the report from TAMU–
ESL.
3. These procedures are the means by
which the Cascade CES units will meet
the standards as set forth by the NEACA
of 1987. Once reviewed by DOE or its
assigns, we assert that the test
procedures presented herein can be
incorporated into the ARI 210/240 as an
approved manner to test multi-blower
coil assemblies like the Cascade Energy
Saver.
4. It is Cascade’s intention to
cooperate with DOE or its assigns, in
rigorously supporting the data presented
herein, the procedure as detailed by
TAMU–ESL, our laboratory, the
efficiencies reported and the
conclusions.
5. Cascade Manufacturing believes
that the benefits to the consumer in the
future usage of this CES unit will be
dramatic in terms of reducing energy
consumption which is the intent of the
NAECA.
Identification of Manufacturers With
Similar Design Characteristics
There are no other known
manufacturers or products that are like
the CES. This is the patented feature of
the CES. The fact that the CES using
multiple blowers is what creates the
problem with the standards as noted
previously in this Petition.
Alternative Test Procedures To
Evaluate Energy Consumption
Characteristics
• Cascade Manufacturing entered into
a testing contract with Texas A&M
University’s Energy Services Laboratory.
The procedure that TAMU–ESL
followed was the ARI 210/240
procedure. TAMU–ESL ‘‘modeled’’ the
Cascade system as a 2 speed blower and
the compressors with 2 stages.
• Thus, TAMU–ESL’s procedure was
to collect data under the Tests A,B,C
and D with all 8 blowers running
(modeled as a single blower) and both
compressors running (modeled as a
single 2 speed compressor) and this is
a full load case. Then, part load
PO 00000

Fmt 4703
Sfmt 4703
conditions were 4 blowers operating
(modeled as a low speed single fan) and
one compressor operating (modeled as a
single compressor in low speed).
• The CES unit had a 5 ton evaporator
coil, split 50%/50% in the sense that it
has a 4 row slab coil with 2 of the rows
being connected to one 2.5 ton heat
pump and the other two rows connected
to the other 2.5 ton heat pump. The slab
coil is patented in its design. It is a face
split. Rows 1 and 3 are connected to one
heat pump and rows 2 and 4 are
connected to the other heat pump. The
coil surface stays wet with one or both
of the heat pumps operating.
• When the full load test was
conducted, all 8 fans were on. The 8
fans are powered by individual 1⁄3hp GE
ECM motors which use 50 watts of
power each, thus 400 watts total for all
8 fans. Each fan was set to blow only
250 cfm at 0.5″ ESP, for a total of 2000
cfm (i.e., 5 tons of air). The outlet from
each of the 8 zones was ducted with flex
into a single 16″ header. The 16″ header
was then ducted into the wind tunnel.
• During the part load test, only four
zone blowers were operating. Each of
these four blowers was delivering 250
cfm at 0.5″; ESP, for a total of 1000 cfm
which is the 400 cfm per ton for 2.5
tons. The ducting was the same as in
full load.
• Tests A,B and C were run in
accordance with the ARI210/240
procedure and pursuant to the notes
summarized above. Test D was not run
since we chose to use the default
coefficient of degradation of 0.25.
• Finally, it is evident to me from
these results that the ARI 210/240
procedures worked for the Cascade unit.
Further, the procedure can and should
be evaluated by the industry bodies that
are responsible for code enforcement to
implement changes accordingly to allow
for testing of Cascade units.

Executive Summary
Cascade Manufacturing, LP (CM)
contracted with the Energy Systems
Laboratory (ESL) to conduct heating and
cooling rating and performance tests on their
multizoned coil blower unit called, ‘‘Cascade
Energy Saver’’ (CES) in accordance with the
ARI Standard for Air Source Split system
heat pumps. The equipment tested consisted
of one CES unit with 8 blowers, one Aspen
5 ton Coil model # BHA40 60+x3 50/50SP (a
two circuit slab coil with TXVs, 2.5 tons per
circuit), and two Amana 2.5 ton Heat pump
model RHF 030—12 SEER.
At the time that this report was written and
the tests were conducted, the ARI 210/240
(Standard) was not clear with a procedure for
the proper rating and performance tests for
an HRCU–A–CB with multiple-zone blowers
as manufactured by CM. In order to obtain
laboratory data that would support an SEER,
HSPF, COP and EER determination, ESL
determined to follow and apply the
Standard’s HRCU–A–CB as closely as
possible (exceptions, deviations and
assumptions to follow in this document). It
appeared to ESL engineers that the Standard
could be applied to the performance ratings
of a CES unit when fixed indoor blower fan
speeds were used in combination with (1.)
traditional 400 cfm per ton and (2.) various
compressor combinations. Before describing
the application of the Standard, a description
of the CES unit will be given in order for the
reader to understand the logic behind the
application of the Standard.
The CES unit consists of two heat pump
units connected to an evaporator that has two
refrigerant circuits. The evaporator is
followed by a plenum which houses multiple
blowers that are independently operated by
a control system developed specifically for
the blower/evaporator/heat pump system.
When in normal operation, the control
system manages the operation of the
compressors and fans in order to meet the
system load as dictated by the multiple
thermostats connected to the controller. The
blower motors are variable speed motors
manufactured by GE, model 2.3 ECM that can
be operated at full capacity during peak
operation or scaled back to lower rotational
speeds at part load conditions. With the
lower rotational speeds, lower cfm rates can
be delivered independently to each zone
connected to the system.
The heat pump condenser units are off-theshelf units and are not manufactured by
Cascade Manufacturing, rather their design
permits the use of any manufactured unit
from companies such as Amana Trane,
Carrier, Lennox, or others. For our tests, we
were supplied with Amana Heat Pumps. The
heat pumps were operated in either an on or
off mode and each one had single speed
compressors and single speed fans. The fact
that there are two heat pumps of equal size
providing the two stages of cooling and
heating with up to 8 indoor fans in a draw
thru configuration to the dual circuit
evaporator coil was the primary reason for
selecting the specific guidelines from the
Standard. The Standard gives detailed
instructions for a variety of compressor
operation combinations but it does not
adequately describe various combinations of
indoor fan(s) and two evaporator/compressor
combinations possible with this unit. It was
decided that the standard descriptions where
the title included ‘‘units with two-speed
compressors, two compressors, or cylinder
unloading’’ most closely matched the
operation of the CES unit. Typically units
with two compressors also have separate
refrigerant circuits on both the indoor and
outdoor coils which match the configuration
of the CES unit.
The two major differences with this system
in light of the Standard was how to apply the
Standard to (1.) a coil blower unit with a 4
row, dual circuited evaporator coil which is
circuited with full face of the 1st and 3rd
rows on one heat pump and rows 2 and 4 on
the second heat pump, (2.) more than one
evaporator blower. The coil blower unit
tested had 8 blowers. The Standard does not
describe how to handle the various air flows
19903
that can be produced with eight blowers. It
was determined that the best way to test the
unit was to apply full-load air flows as
determined by nominal 400 cfm per ton
(compressor) operation. For example, if both
2.5 ton heat pumps were operating, the rated
air flow that was tested was 2,000 cfm. With
one heat pump running, the coil blower unit
would have half the heating/cooling capacity
therefore the full load air flow would be
1,000 cfm which is half of the two heat pump
supply side air flow. This interpretation of
the Standard was used for both heating and
cooling tests.
For cooling, testing was done following the
guidelines in ARI 210/240 section A2.1.3.
Tests A, B, and C were conducted for both
single heat pump and two heat pump
operation. Test D was not done and the
default CD of 0.25 was used for SEER
calculations. The indoor air-enthalpy method
was used during the tests. A description of
the test facilities and the energy balance
method is included below. Proper energy
balances were achieved for all tests as were
within the specifications of the standard. The
results of the cooling tests are included in the
table below.
For heating, testing was done following the
guidelines in ARI 210/240 section A2.2.2.
Tests were conducted at 62F (one heat
pump), 47F (one and two heat pumps), 35F
(one and two heat pumps), and 17F (two heat
pumps). The indoor air-enthalpy method was
used during the tests. Proper energy balances
were achieved on all test except the 17F test.
Due to the cycling of the heat pumps between
heating and defrost, two phase transients in
the refrigerant circuit prevented a good
measurement of the refrigerant flow until the
unit reached steady state. The period of time
where the refrigerant was in two phases was
sufficient to prevent a proper energy balance
from being achieved. The air-side
measurements were taken with the same
instrumentation during the 17F tests as were
used during all other testing. It is reasonable
to assume the air side measurements were
accurate during the 17F tests since proper
energy balances were achieved during all
other tests. The results of the heating tests are
included in the table below.

The outdoor room section is the
condensing sections for the heat pump units
(compressors and outdoor coils) plus the
outdoor airflow chamber. Conditioned
outdoor air enters the outdoor coil and is
exhausted to the outdoor room. Outdoor
airflow rates were not measured for these
units. Air is drawn in through all sides of the
outdoor unit and discharged through the top
of the unit. A sampler mounted around the
outdoor coils measured dry-bulb temperature
and relative humidity as it entered the
condensers.
The instrumentation for all tests is divided
into air-side and refrigerant-side
measurements. The air-side temperature
measurements for both the inlet and outlet of
the indoor coil unit are made using type-T
thermocouple grids. A combination of dew
point and relative humidity sensors were
used for the inlet and outlet of indoor coil
unit. For the outdoor unit, both temperature
and humidity were measured on the inlet
side of the condenser. Because the indoor
enthalpy method was used for all tests,
condenser outlet RH was not measured. Both
inlet and outlet temperatures were be
measured with type-T thermocouples.
temperature. Reheat in each room is provided
by four banks of 9.9 kW electrical strip
heaters in the conditioning ductwork. The
cooling coil is supplied with a water ethylene
glycol solution from the chiller. A 1000
gallon water storage tank is mounted in the
system to stabilize the chilled water
temperature and reduce the cycling of the
chiller. Steam from an electric-fired boiler
and dehumidification coils control the
humidity in the rooms. The dehumidification
coils are fed from the same cool storage tank
as the cooling coils. The boiler supplies
steam directly into the supply air duct. Room
temperature is maintained by adjusting the
chilled water flow to coils with VSD driven
pumps in combination with the operation of
the reheat coils.
The indoor test section includes the indoor
air flow chamber and the indoor fan coil
section. The air flow chamber fan draws
conditioned air from the indoor room
through the indoor test section. An adjustable
damper is used to maintain the amount of air
flow specified for each unit. After leaving the
air flow chamber, conditioned air is routed
back into the indoor room. Figure 1 shows a
sketch of the indoor and outdoor rooms as
used for these tests.
BILLING CODE 6450–01–P
Refrigerant-side temperatures and
pressures were measured throughout the
system. Refrigerant-side test points are
shown on Figure 2. With the exception of the
refrigerant flow rate, the outdoor unit power,
and the air flow differential pressure, the rest
of the measurements are temperatures (drybulb, wet-bulb, dew point) and pressures.
Refrigerant mass flow was measured with a
Coriolis-type flow meter placed on the liquid
line after the condensing section of the heat
pump unit (Figure A.2) for both heat pumps
units. Separate mass flow meters were used
for each heat pump unit.
The data acquisition system converted
signals coming from all the sensors in the
indoor and outdoor rooms into temperatures,
pressures, flow rates, or power. A data logger
was used to collect data from the testing
apparatus. The logger is linked to a computer
where the data was visually displayed during
testing. Once a test was complete, the data
was transferred to another computer for
processing. Each channel was scanned by the
logger at regular intervals and the data was
stored every thirty seconds. A minimum of
one hour of steady state data was collected
as per the standard’s specifications for
cooling and 30 minutes for heating. For
cooling tests A and B, steady state was
maintained for one hour before the start of
data collection in order to ensure that steady
state dehumidification had been achieved. A
description of the data acquisition test points
is listed in Table 1.

Facilities and Procedure
All of the tests were conducted in the
psychrometric rooms at the Energy Systems
Laboratory which is part of the Texas
Engineering Experiment Station a division
within the Texas A&M University System.
These rooms were completed in 1986 and
have been used for research projects and
industry testing. The rooms were designed
for testing of systems with cooling capacities
up to 10 tons. Chilled water is provided to
the rooms by a 75 ton Trane screw chiller.
Reheat is provided by 40 kW of electrical
strip heaters in the conditioning ductwork. In
addition, a desiccant system is used to
provide low humidity conditions in either
room. The psychrometric rooms allow indoor
and outdoor dry-bulb and wet-bulb
temperatures to be maintained within
approximately ± 0.3 °C (0.5 °F) during steady
state operations. Temperatures from 17 °F to
120 °F have been maintained for tests in the
rooms for previous tests. The rooms are
capable of running all standard ARI 210/240
(ARI 2003) and ASHRAE 37/116 (ASHRAE
1988 and 1983) unitary heat pump and air
conditioners tests, which include both
heating and cooling mode.

and running the selected tests. The tests
conducted were selected by following the
Standard, HRCU–A–CB. The Standard did
not describe how to test a unit with eight
indoor blowers, dual circuited evaporator
coil and two heat pump units. Since the
Standard did describe how to test a unit with
two compressors which closely models the
heat pumps, it was decided to follow the two
compressor model of the Standard for all
tests. Because of the way the CES proprietary
control system operated the eight indoor
blowers, it was decided to use 400 cfm per
ton air flow for each compressor (2.5 ton heat
pump).
When test points were selected from the
guidelines, tests were conducted at the
appropriate indoor and outdoor temperatures
for single heat pump operation and when
both heat pump units were operating. There
were three exceptions. When in cooling
mode, Test C was conducted for full load
operation only. When in heating mode the
62F test was conducted with only single heat
pump in operation while the 17F test was
conducted for dual condenser operation only.
The test point room conditions were as
specified by the Standard 210/240
guidelines.
When cooling tests were conducted the
moisture measurements were made using
chilled mirror hygrometers in combination
with relative humidity sensors as a backup.
In addition to the two sensors, condensate
was collected during all A and B tests. The
energy balances were based on the amount of
condensate collected. During the last few
cooling tests, the hygrometer used to measure
moisture at the evaporator exit failed. For
these tests, the sensible capacity was
calculated using the formula btuh =
1.1*cfm*(Tair_entering¥Tair_exiting). The latent
capacity was calculated from the measured
condensate for all A and B tests. For heating
tests, the chilled mirror hygrometers were
replaced with relative humidity sensors.

SUPPLEMENTARY INFORMATION:
I. Background and Authority
II. Petition for Waiver
III. Application for Interim Waiver
IV. Alternate Test Procedure
V. Summary and Request for Comments
I. Background and Authority
Title III of the Energy Policy and Conservation Act (EPCA) sets
forth a variety of provisions concerning energy efficiency. Part C of
Title III (42 U.S.C. 6311-6317) provides for an energy efficiency
program entitled ``Certain Industrial Equipment,'' and includes
commercial air conditioning equipment, packaged boilers, water heaters,
and other types of commercial equipment.
Today's notice involves commercial equipment under Part C, which
specifically provides for definitions, test procedures, labeling
provisions, energy conservation standards, and the authority to require
information and reports from manufacturers. With respect to test
procedures, Part C generally authorizes the Secretary of Energy to
prescribe test procedures that are reasonably designed to produce
results which reflect energy efficiency, energy use and estimated
operating costs, and that are not unduly burdensome to conduct. (42
U.S.C. 6314(a)(2)).
For commercial package air conditioning and heating equipment, EPCA
provides that the test procedures shall be those generally accepted
industry testing procedures or rating procedures developed or
recognized by the Air-Conditioning and Refrigeration Institute (ARI) or
by the American Society of Heating, Refrigerating and Air Conditioning
Engineers (ASHRAE), as referenced in ASHRAE/IES Standard 90.1 and in
effect on June 30, 1992. (42 U.S.C. 6314(a)(4)(A)) This section also
provides for the Secretary of Energy to amend the test procedure for a
product if the industry test procedure is amended, unless the Secretary
determines that such a modified test procedure does not meet the
statutory criteria. (42 U.S.C. 6314(a)(4)(B)) On October 21, 2004, DOE
published a direct final rule, effective December 20, 2004, adopting
ARI Standard 210/240-2003 for small commercial package air conditioning
and heating equipment with capacities < 65,000 Btu/h and ARI Standard
340/360-2000 for large commercial package air conditioning and heating
equipment with capacities >= 135,000 Btu/h and < 240,000 Btu/h and
small commercial package air conditioning and heating equipment with
capacities >= 65,000 Btu/h and < 135,000 Btu/h. 69 FR 61962, October
21, 2004. According to Cascade, both ARI Standard 340/360-2000 and ARI
Standard 210/240-2003 are applicable to Cascade's Cascade Energy Saver
(CES) products. However, Cascade only seeks a waiver from ARI Standard
210/240-2003.
DOE's regulations set forth under 10 CFR 431.401 contain provisions
allowing a person to seek a waiver from the test procedure requirements
for commercial equipment. The waiver provisions allow the Assistant
Secretary for Energy Efficiency and Renewable Energy (hereafter
``Assistant Secretary'') to temporarily waive test procedures for a
particular basic model when a petitioner shows that the basic model
contains one or more design characteristics which either prevent
testing according to the prescribed test procedures, or when the
prescribed test procedures may evaluate the basic model in a manner so
unrepresentative of its true energy consumption as to provide
materially inaccurate comparative data. 10 CFR 431.401(a)(1). The
Assistant Secretary may grant the waiver subject to conditions,
including adherence to alternate test procedures. 10 CFR 431.401(f)(4).
Petitioners are to include in their petition any alternate test
procedures known to evaluate the basic model in a manner representative
of its energy consumption. 10 CFR 431.401(b)(1)(iii). Waivers generally
remain in effect until final test procedure amendments become
effective, thereby resolving the problem that is the subject of the
waiver. 10 CFR 431.401(g).
The waiver process also allows the Assistant Secretary to grant an
interim waiver from test procedure requirements to manufacturers who
have petitioned DOE for a waiver of such prescribed test procedures. 10
CFR 431.401(a)(2). An interim waiver remains in effect for a period of
180 days or until DOE issues its determination on the petition for
waiver, whichever is sooner, and may be extended for an additional 180
days, if necessary. 10 CFR 431.401(e)(4).
II. Petition for Waiver
On July 22, 2005, Cascade filed the Cascade Petition for Waiver and
its Application for an Interim Waiver from the test procedures
applicable to commercial package air conditioning and heating
equipment. On May 26, 2006, Cascade filed an amended Petition for
Waiver listing all the basic models for which Cascade seeks a waiver.
In particular, Cascade requested a waiver from the commercial test
procedures contained in ARI Standard 210/240-2003 for the system
combinations listed in Table 1, attached to its amended Petition.
Cascade seeks a waiver from the test procedures in ARI Standard
210/240-2003 and asserts that the design characteristics of the CES
systems prevent testing according to these prescribed test procedures.
In particular, Cascade states that the CES indoor-coil blower models
have more than one blower per coil and up to and as many as eight
blowers that operate independently. Cascade claims that its products do
not conform to the test procedures in ARI Standard 210/240-2003,
because these test procedures are based on a system with only one
indoor-coil blower.
Cascade asserts that with slight modifications to ARI 210/240
procedures, CES units can be tested and that such testing can provide
measurements to satisfactorily determine the Seasonal Energy Efficiency
Ratio (SEER) and the Heating Seasonal Performance Factor (HSPF).
Cascade included in its petition sample SEER calculations, sample test
procedures used to derive the SEER calculations, and sample test data.
The testing, contracted by Cascade to Texas A&M University Energy
Services Laboratory (hereafter ``TAMU-ESL''), provides data on a system
with two 2.5-ton Amana RHF 030 heat pump units of SEER 12 connected to
a dual-circuit evaporator coil, followed by a plenum housing 8 blowers
operated by a control system. Using a test procedure based on ARI 210/
240, TAMU-ESL calculated a SEER value of 18.1 and an HSPF of 9.5.
Details of the testing are provided in the Cascade Petition, published
in full, below.
III. Application for Interim Waiver
Cascade also requested immediate relief through its Application for
Interim Waiver to avert undue economic hardship. According to DOE
regulations, an interim waiver may be granted if it is determined that
the applicant will experience economic hardship if the application for
interim waiver is denied, if it appears likely that the petition for
waiver will be granted, and/or the Assistant Secretary determines that
it would be desirable for public policy reasons to grant immediate
relief
[[Page 19893]]
pending a determination of the petition for waiver. 10 CFR
431.401(e)(3).
Cascade's Application for Interim Waiver does not provide
sufficient information to evaluate what, if any, economic impact or
competitive disadvantage Cascade will likely experience absent a
favorable determination on its application. It also does not provide
sufficient information to determine if there are public policy reasons
to grant immediate relief. Furthermore, DOE has never granted a
previous waiver for a similar product design. Thus, the likelihood of
granting the waiver is unclear until further information and comment is
provided.
Therefore, Cascade's Application for an Interim Waiver from the DOE
test procedure for its CES products is denied. Hence, it is ordered
that: The Application for Interim Waiver filed by Cascade is hereby
denied for Cascade's CES air conditioners and central air conditioning
heat pumps.
This denial of Cascade's Application for Interim Waiver is based
upon the presumed validity of statements and allegations submitted by
the company. This denial of Interim Waiver may be modified if DOE
receives information that justifies granting an Interim Waiver.
IV. Alternate Test Procedure
DOE will make its judgment on the Cascade Petition after the period
for public comment ends. However, should DOE grant Cascade a waiver
from the applicable test procedures, DOE would likely prescribe an
alternate test procedure. Manufacturers face restrictions with respect
to making representations about the energy consumption and energy
consumption costs of products covered by EPCA. (42 U.S.C. 6314(d))
Consistent representations are important for manufacturers to make
claims about the energy efficiency of their products. For example, they
are necessary to determine compliance with state and local energy codes
and regulatory requirements, and can provide valuable consumer
purchasing information. Therefore, DOE is considering an alternate test
procedure for Cascade. DOE is publishing the proposed alternate test
procedure in this notice to account for the potential need for an
alternate test procedure and to allow the public to comment on a
proposed alternate test procedure.
Cascade included a description of an alternate test procedure and
test data for a sample system in its Petition. DOE is considering
prescribing an alternate test procedure that takes into account the
information Cascade provided in the petition. In particular, the
proposed alternate test procedure would require Cascade to test units
according to ARI Standard 210/240-2003, but permit Cascade to use
alternate requirements when testing systems that have multiple fans per
indoor coil.\1\ Cascade may test systems with multiple indoor fans that
jointly provide the total indoor-coil airflow rate required for the
capacity being tested, however, Cascade would be required to adhere to
the airflow requirement of section 6.1.3.3 of ARI Standard 210/240-
2003, which sets an upper limit on indoor-coil airflow according to
system capacity.\2\ During testing, the individual indoor fans would
each deliver an equal portion of the total required airflow.
---------------------------------------------------------------------------
\1\ For example, according to a 450 cfm/ton requirement, a 5 ton
unit would be permitted to have an airflow rate of 2,250 cfm or
lower. If that system were to operate at 2,000 cfm and have 8 fans,
each fan would blow 250 cfm. In addition, if that same system were
to operate at partial load with 2.5 tons of capacity, the tester
could operate 4 fans with each fan blowing 250 cfm.
\2\ For example, section 6.1.3.3 requires equipment with indoor
fans intended for use with field installed duct systems to be rated
at the indoor-coil airflow rate of equal to or less than 37.5 SCFM
per 1,000 Btu/h of rated capacity.
---------------------------------------------------------------------------
DOE generally agrees with TAMU-ESL's testing and analysis of a
system with a CES 5-ton, 8-zone unit connected to an Amana RHF030 heat
pump with a SEER of 12-14. As each Amana RHF030 heat pump uses a
single-speed compressor, DOE agrees with TAMU-ESL's choice to treat the
system as a two-speed blower with a two-stage compressor and test the
system according to A2.2.2 and A2.1.3. Furthermore, DOE agrees with
TAMU-ESL's decision to ensure a total indoor-coil airflow rate of
around 2,000 cfm with eight blowers providing 250 cfm each, when
operating the system at a full capacity. For low-speed conditions,
TAMU-ESL operated the system at a 2.5-ton capacity and ensured a total
indoor-coil airflow rate of around 1,000 cfm, with four blowers
providing 250 cfm each.
However, it is not clear why TAMU-ESL conducted Test C for full
load operation only, though section A3.1.3 indicates that if one
chooses to perform Test C, the system must be tested at low-speed.
Furthermore, for certification, testing conditions must fall within the
applicable tolerances provided in ARI 210/240-2003. Finally, while DOE
generally approves of the TAMU-ESL method to test a CES multi-blower
unit paired with two Amana RHF030 heat pumps, DOE would expect Cascade
to test its units according to those appropriate tests, procedures and
conditions generally stated in ARI 210/240-2003. For example, testing
of a CES unit paired to a variable-speed compressor should follow the
procedures and requirements described for a system with a variable-
speed compressor in A2.1.6.
Given consideration of the information provided to DOE in the
Cascade Petition, DOE is considering the following alternate test
procedure:
Alternate test procedure. Cascade shall be required to test the
products covered under this Waiver according to the prescribed tests,
conditions, and procedures referenced in ARI Standard 210/240-2003,
except that Cascade shall be permitted to test systems with indoor
units that have multiple fans. As such, Cascade shall be required to
meet the usual indoor-coil airflow rate requirements of ARI Standard
210/240-2003, section 6.1.3.3. However, tested units may run multiple
indoor-coil fans which collectively meet the required indoor-coil
airflow rates per capacity. To determine the level at which to operate
the indoor fans during testing, Cascade may divide the total indoor-
coil airflow rate at full load, by the number of indoor fans in the
tested system. During testing, Cascade shall run the indoor fans at
this level, and may decide how many indoor fans to operate by dividing
the total indoor-coil airflow required at the capacity being tested by
the indoor fan level, as determined above. Cascade may make
representations of the CES products covered in this Waiver, consistent
with the provisions outlined in this alternate test procedure.
V. Summary and Request for Comments
Today's notice announces the Cascade Petition for Waiver and denies
Cascade's Application for Interim Waiver from the test procedures
applicable to Cascade's CES air conditioner and heat pump units. DOE is
publishing the Cascade Petition for Waiver in its entirety. The Cascade
Petition contains no confidential information. Furthermore, today's
notice includes an alternate test procedure that the DOE is considering
including in the subsequent Decision and Order, should DOE decide to
grant Cascade a Waiver.
DOE is interested in receiving comments on all aspects of this
notice. DOE is particularly interested in receiving comments and views
of interested parties concerning whether to grant the Cascade Petition
and regarding the proposed alternate test procedure. Specifically, DOE
would like to receive comment on the following questions:
Does this alternate test procedure adequately specify how
to handle
[[Page 19894]]
airflows when testing a system with multiple blowers?
In the proposed alternate test procedure, fans are to run
at a set cfm per fan throughout a test. Is this appropriate or should
DOE allow fans to run at different cfm's throughout a test while still
meeting the required overall indoor-coil airflow rate according to
capacity?
Cascade states that the current test procedure is not
specific about the method of configuring a dual-circuited evaporator
coil to blowers. However, Cascade does not propose specific language.
Does the alternate test procedure proposed in this notice need to
specifically address configurations of dual-evaporator coils and coil-
blowers?
DOE is interested in receiving general comments on
possible modifications to any test procedures or alternative rating
methods that DOE could use to fairly represent the energy efficiency of
Cascade's CES products.
Any person submitting written comments must also send a copy of
such comments to the Petitioner, whose contact information is cited
above. 10 CFR 431.201(d)(2).
