DEPARTMENT OF ENERGY
[Docket No. EERE-2007-BT-WAV-0004]
Energy Conservation Program for Consumer Products: Decision and
Order Granting a Waiver to Cascade Group, LLC From the Department of
Energy Residential Central Air Conditioner and Heat Pump Test Procedure
[Case No. CAC-013]
AGENCY: Office of Energy Efficiency and Renewable Energy, Department of
Energy.
ACTION: Decision and Order.
-----------------------------------------------------------------------
SUMMARY: This notice announces the Department of Energy's Decision and
Order in Case No. CAC-013, which grants a waiver to Cascade Group, LLC
(Cascade) from the existing Department of Energy (DOE) residential
central air conditioner and heat pump test procedure for its product
line of residential Cascade Energy Saver (CES) multi-blower air-
conditioning and heating equipment. DOE is granting a waiver because
the multi-blower feature of these products, which impacts the
calculation of energy efficiency, is not accounted for in the DOE test
procedure. As a condition of this waiver, Cascade must test and rate
the energy consumption of specified CES products (indoor units combined
with the listed outdoor units) according to the alternate test
procedure set forth in this notice.
DATES: This Decision and Order is effective August 28, 2008, and will
remain in effect until the effective date of a DOE final rule
prescribing an amended test procedure appropriate for the model series
of Cascade CES central air conditioners and heat pumps covered by this
waiver.

SUPPLEMENTARY INFORMATION: In accordance with 10 CFR 430.27(l), DOE
gives notice of the issuance of its Decision and Order as set forth
below. In the Decision and Order, DOE grants Cascade a waiver from the
existing residential central air conditioner and heat pump test
procedures under 10 CFR Part 430, Subpart B, Appendix M, for its CES
multi-indoor blower-motor products, subject to a condition requiring
Cascade to test and rate its CES products pursuant to the alternate
test procedure provided in this notice. DOE is granting the waiver
because the multi-blower feature of these products, which impacts the
calculation of energy efficiency, is not accounted for in the DOE test
procedure. Today's Decision and Order requires that Cascade may not
make any representations concerning the energy efficiency of these
products unless such product has been tested in accordance with the DOE
test procedure, consistent with the provisions and restrictions in the
alternate test procedure as set forth in the Decision and Order below,
and such representations fairly disclose the results of such
testing.\1\ (42 U.S.C. 6293(c))
---------------------------------------------------------------------------
\1\ Consistent with the statute, distributors, retailers, and
private labelers are held to the same standard when making
representations regarding the energy efficiency of these products.
(42 U.S.C. 6293(c))
Issued in Washington, DC, on August 8, 2008.
Alexander A. Karsner,
Assistant Secretary, Energy Efficiency and Renewable Energy.
Decision and Order
In the Matter of: Cascade Group, LLC (Cascade) (Case No. CAC-013).
Background
Title III of the Energy Policy and Conservation Act (EPCA) sets
forth a variety of provisions concerning energy efficiency, including
Part A \2\ of Title III which establishes the ``Energy Conservation
Program for Consumer Products Other Than Automobiles.'' (42 U.S.C.
6291-6309) Part A includes definitions, test procedures, labeling
provisions, energy conservation standards, and the authority to require
information and reports from manufacturers. Further, Part A authorizes
the Secretary of Energy (the Secretary) to prescribe test procedures
that are reasonably designed to produce results which measure energy
efficiency, energy use, or estimated annual operating cost, and that
are not unduly burdensome to conduct. (42 U.S.C. 6293(b)(3))
---------------------------------------------------------------------------
\2\ This part was originally titled Part B; however, it was
redesignated Part A, after Part B of Title III was repealed by
Public Law 109-58.
---------------------------------------------------------------------------
Relevant to the current Petition for Waiver, the test procedures
for residential central air conditioners and heat pumps are codified in
10 CFR part 430, Subpart B, Appendix M. On October 22, 2007, DOE
amended the test procedures for residential central air conditioners
and central air conditioning heat pumps to implement test procedure
changes for small-duct, high-velocity systems, two-capacity units, and
to update references to the current American Society of Heating,
Refrigerating, and Air-Conditioning Engineers (ASHRAE) standards. 72 FR
59906. The October 22, 2007 final rule became effective on April 21,
2008. However, these amendments did not solve the problem raised by
Cascade in its petition.
DOE regulations for covered products contain provisions allowing
any interested person to seek a waiver from the test procedure
requirements for covered consumer products when the petitioner's basic
model contains one or more design characteristics that 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 430.27(a)(1).
Petitioners must include in their petition any alternate test
procedures known to evaluate the basic model in a manner representative
of its energy consumption. (10 CFR 430.27(b)(1)(iii))
The Assistant Secretary for Energy Efficiency and Renewable Energy
(the Assistant Secretary) may grant a waiver subject to conditions,
including adherence to alternate test procedures. 10 CFR 430.27(l).
Waivers generally terminate on the effective date of a final rule which
prescribes amended test procedures appropriate to the model series
manufactured by the petitioner, thereby eliminating any need for the
continuation of the waiver. 10 CFR 430.27(m).
The waiver process contained in DOE's regulations also allows any
interested person who has submitted a Petition for Waiver to file an
Application for Interim Waiver of the applicable test procedure
requirements. 10 CFR 430.27(a)(2). The Assistant Secretary will grant
an Interim Waiver request if it is determined that the applicant will
experience economic hardship if the 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 pending a determination on the
Petition for Waiver. 10 CFR 430.27(g). An Interim Waiver remains in
effect for a period of 180 days or until DOE issues a determination on
the Petition for
[[Page 50788]]
Waiver, whichever occurs first, and may be extended by DOE for 180
days, if necessary. 10 CFR 430.27(h).
On July 22, 2005, Cascade filed a Petition for Waiver and an
Application for Interim Waiver from the test procedures applicable to
its CES line of residential multi-blower air-conditioning and heating
equipment. The DOE test procedures have provisions for central air
conditioners with one blower and one indoor coil (the most common
type), and for multi-splits, which have multiple refrigerant lines
running to multiple indoor fan-coil units. The Cascade product line has
one indoor coil with multiple blowers distributing air to a number of
outlets. The DOE test procedure does not cover this situation, which,
so far, is unique to Cascade's products.
Cascade's petition requested a waiver from ARI 210/240, but this is
not the applicable test procedure; instead, as explained below, the
applicable test procedures are those residential test procedures
contained in 10 CFR part 430, Subpart B, Appendix M. For the CES multi-
blower product line at issue here, all of the outdoor units involve
single-phase equipment both for residential and commercial use. There
is no prescribed test procedure in 10 CFR part 431, Energy Efficiency
Program for Certain Commercial and Industrial Equipment, for single-
phase, small commercial package air-conditioning and heating equipment.
A waiver is nonetheless required for this single-phase equipment
because Cascade's multi-blower products are properly classified as
``consumer products'' under 42 U.S.C. 6291(1). ``Consumer products''
are ones which, to a significant extent, are for personal use. Small
commercial single-phase package air-conditioning and heating equipment
meet this definition, given their frequent residential applications.
(42 U.S.C. 6291(1)(B)) Thus, the Cascade CES products in question here
require a waiver from DOE's test procedure for residential central air
conditioners and heat pumps, under 10 CFR part 430, Subpart B, Appendix
M.
Cascade seeks a waiver from the applicable test procedures because
the multi-blower feature of Cascade's equipment prevents testing
according to the currently prescribed test procedures under 10 CFR part
430. Consequently, Cascade has submitted an alternate test procedure to
DOE for approval that can be used to determine the performance of its
CES products. The alternate test procedure provides rules and
algorithms so that, regardless of the actual number of blowers and heat
pumps, the test procedure will model the CES system as a one-blower
evaporator with a two-speed fan and one heat pump with one or more
speeds.
On April 20, 2007, DOE published in the Federal Register Cascade's
Petition for Waiver and solicited public comments. 72 FR 19891.
Cascade's Application for Interim Waiver was denied because it did not
provide sufficient information to evaluate economic impact or
competitive disadvantage or to determine public policy reasons to grant
immediate relief. Also, DOE has never granted a waiver for a similar
product design, so the likelihood of granting the waiver was unclear.
DOE received one comment from Joseph A. Pietsch, P. E., which
supported granting the waiver and Cascade's alternate test procedure
``as an acceptable approach for rating the performance of the subject
heat pump.''
Assertions and Determinations
Cascade's Petition for Waiver
On July 22, 2005, Cascade submitted a Petition for Waiver and an
Application for Interim Waiver from the test procedures applicable to
residential and commercial air-conditioning and heating equipment, for
its new line of CES models of central air conditioners and heat pumps.
As explained above, only a waiver from the residential test procedure
in 10 CFR part 430, Subpart B, Appendix M is needed.
Cascade claims that the energy consumption of its CES systems
cannot be accurately measured using the existing test procedures for
the following reasons: (1) the DOE test procedure stipulates that the
unit meet the maximum standard airflow rate of 37.5 cubic feet per
minute (CFM)/1000 British thermal units/hour (Btu/hr); \3\ and (2) this
CFM is applicable to an indoor unit that has only one blower-motor. The
CES unit has from two to eight indoor blower-motors that are
independently operating. The DOE test procedure has no guidance
concerning the number of blowers that should be operating, the
apportionment of the air flow among the multiple blowers, or the test
set-up for a multi-blower system. Cascade seeks a waiver because, it
asserts, the current procedures for testing do not apply. Therefore,
the Cascade Petition requested that DOE grant a waiver from the
existing test procedures until such time as a representative test
procedure is developed and adopted for this class of products.
---------------------------------------------------------------------------
\3\ 10 CFR part 430, Subpart B, Appendix M, section 3.1.4.1.1.
---------------------------------------------------------------------------
In support of its petition, Cascade also submitted an alternate
test procedure that would be applicable to all of its configurations of
CES models of air conditioners and heat pumps. Cascade modified its
petition on May 26, 2006, and again on April 16, 2007, after
consultation with the National Institute of Standards and Technology
(NIST). NIST found that there had been limitations in the original
modeling rules, and supplied more comprehensive rules for modeling the
CES systems. On August 15, 2007, Cascade submitted to DOE a set of
general rules and set-up procedures to be used when testing its CES
models, but with slight variations in testing tailored to each
different system.
Specifically, Cascade asserted that its alternate test procedure
may be used for rating its CES multiple blower-coils in combination
with specified condensing units from other manufacturers. In large
part, the alternate test procedure is essentially the same as the
current test procedure for central air conditioners and heat pumps in
10 CFR part 430, Subpart B, Appendix M. However, Cascade's alternate
test procedure differs from the prescribed test procedure because it
covers indoor blower coils that have more than one indoor blower and
motor. Cascade's Petition for Waiver described Cascade's alternate test
procedure for a particular configuration with two heat pumps and eight
blowers, and Cascade subsequently supplied methodological rules and
set-up procedures to describe how its alternate test procedure would be
used to test other configurations.
DOE understands that, using the current central air conditioning
and heat pump test procedure, the company cannot calculate the seasonal
energy efficiency ratio (SEER) and the heating seasonal performance
factor (HSPF) for its CES products. Based on the above, DOE believes
that the identified problems would prevent testing of Cascade's CES
basic models according to the existing test procedure. However, the
alternate test procedures described in Cascade's Petition for Waiver
will enable Cascade to calculate these energy efficiency measures.
After careful consideration, DOE has decided to adopt the alternate
test procedure suggested by Cascade to test its CES line of air
conditioners and heat pumps, including the relevant rules and set-up
requirements.
Consultations With Other Agencies
DOE consulted with Federal Trade Commission (FTC) staff and NIST
concerning the Cascade Petition for Waiver. The FTC staff did not have
any
[[Page 50789]]
objections to granting a waiver to Cascade. NIST provided a technical
review of the alternate test procedure.
Conclusion
After careful consideration of all the materials submitted by
Cascade, the comment received, the review by National Institute of
Standards and Technology, and consultation with FTC staff, it is
ordered that:
(1) The ``Petition for Waiver'' filed by Cascade Group, LLC
(Cascade) (Case No. CAC-013) is hereby granted, subject to the
provisions of paragraphs (2), (3), (4), and (5) of this Order.
(2) Cascade shall not be required to test or rate its Cascade
Energy Saver (CES) line of central air conditioners and heat pumps, as
listed below, on the basis of the test procedures specified in 10 CFR
part 430, Subpart B, Appendix M, but shall be required to test and rate
such products according to the alternate test procedure set forth in
Appendix A (see Cascade's Petition for Waiver, which published in the
Federal Register on April 20, 2007, 72 FR 19891), as well as the table
of system configurations in paragraph (3)(B); the rules for
generalizing the test procedure modifications in paragraph (3)(B); and
the test procedure set-up requirements in paragraph (4).

(3) Alternate Test Procedure
(A) Cascade shall be required to test the products listed in
paragraph (2) according to those test procedures for residential
central air conditioners and heat pumps prescribed by DOE at 10 CFR
part 430, Subpart B, Appendix M, except that Cascade shall test such
products in accordance with the provisions of subparagraph (B) of this
paragraph. Furthermore, Cascade shall make representations concerning
its CES multi-blower products covered by this waiver according to the
provisions of subparagraph (C) below.
(B) Cascade shall test the CES products covered by this waiver
under 10 CFR Part 430, Subpart B, Appendix M, as supplemented by the
following:
(1) Appendix A
Cascade shall test according to the modifications to the test
procedure for residential central air conditioners and heat pumps
contained in Appendix A (which is consistent with the appendix
submitted as part of Cascade's Petition for Waiver), as supplemented by
the rules set forth in subparagraph (B)(3) and the set-up requirements
in subparagraph (B)(4).
(2) Table of System Configurations
Cascade shall test according to the CES system configurations in
the following table:
BILLING CODE 6450-01-P
[[Page 50797]]
[GRAPHIC] [TIFF OMITTED] TN28AU08.000
BILLING CODE 6450-01-C
[[Page 50798]]
(3) Rules for Generalizing the Specific Test Procedure Modifications
Cascade shall test its CES products according to the following
rules:
Rule One: These rules apply to testing of residential CES systems
ranging from two-ton/single-speed/two-blower models up to and including
dual-2.5-ton heat pump/eight-zone models. It also applies to all CES
model configurations in between for cooling and heating with single-
phase units that are less than 65,000 btu/hr.
Rule Two: A 400 cubic feet/minute (cfm) per ton nominal evaporator
air flow rate will be used, not to exceed 450 cfm per ton on the high
end (same as 37.5 cfm per 1000 BTU/hr capacity).
Rule Three: The CES configurations should be tested so that
regardless of the number of blowers and heat pumps, the resultant test
procedure will model the CES system as a one-blower evaporator with a
two-speed fan and one heat pump with one or more speeds. The test
procedure will follow the procedure found in 10 CFR part 430, Subpart
B, Appendix M. For example, two heat pumps are to be modeled as a
single heat pump with two speeds. Also, dual two-speed heat pumps are
to be modeled as a single heat pump with four speeds. Further, given
that the number of indoor blowers may range from two to eight per unit,
these will be modeled as a single blower with two speeds such that half
the fans will be used to blow air at low speed; when operated at high
speed, all fans will operate such that the air flow delivered per fan
equals in total the air flow needed for the total heat pump capacity
(i.e., 800 cfm for a two-ton heat pump).
Rule Four: For an even number of blowers, the air flow per blower
is the same, and the sum of the air flow per blower equals the total
air flow. For odd number of blowers, see Rule Five.
Rule Five: If the number of fans is an odd number, divide the
number of fans by two. Round the quotient up to a whole number, and
define this whole number as the quantity of ``low-speed fans.'' In the
case of three blowers, low-speed mode will have two blowers and the
remaining blower will be used only in high-speed mode. These are
electrically commutated motors \4\ (ECMs), so adjust the speed of the
fans that are part of ``low-speed'' mode so that each blower produces
an equal share of the low-speed air quantity. Likewise, the third
blower, which operates during high-speed mode, blows an air flow equal
to half of the total air flow for the tonnage of the heat pump(s). This
is accomplished by adjustment of the ECM for the single fan, which runs
in high-speed mode to produce half the total air flow needed for the
total tonnage.
---------------------------------------------------------------------------
\4\ An ``electronically commutated motor'' is a high-efficiency,
programmable, brushless, direct-current (DC) motor utilizing a
permanent magnet motor and a built-in inverter. DC motors are
significantly more energy efficient than alternating current (AC)
motors and much easier to control.
---------------------------------------------------------------------------
Rule Six: Once the CES system is modeled as required under Rules
One through Five, perform Tests A, B, C and D (or if the default is
accepted, then Test D is not required) as found in the procedure of 10
CFR 430, Subpart B, Appendix M for cooling and heating for the
variations in speeds and settings found therein.
(4) Test Procedure Set-Up Requirements
When testing its CES products, Cascade shall adhere to the
following test procedure set-up requirements:
(a) Piping: Determine the number of heat pumps. Connect the heat
pump to the evaporator coil circuit, whether single- or dual-circuit.
Thus, if there are two heat pumps, there is a heat pump piped into one
of the circuits of the evaporator coil, while the second heat pump is
piped into the second circuit of the evaporator coil.
(b) Unit sizing: If two heat pumps are used, they shall be equal in
tonnage. Thus, a four-ton Cascade unit will have dual two-ton heat
pumps attached.
(c) Fans' cfm sizing: As set forth in Rules Two through Five,
blowers shall be driven by ECM motors, and the cfm for each blower
shall be as calculated under Rules Four and Five.
(d) Ducting the blowers: The discharge of each blower will be
connected so that the total cfm from all blowers is collected into a
single duct, sized consistent with appropriate industry pressure-drop
standards and ducted to the wind tunnel.
(e) Pressures, delta Ps, temperatures, and other metric points:
These values are measured by installing devices appropriately
calibrated to National Institute of Standards and Technology-traceable
standards for refrigerant and condensate pipes, circuits and air flows
in the evaporator coil, and condenser coils to measure quantities to be
used for the calculation of capacities in heating and cooling modes in
tests A, B, C, and D.
(C) Representations. In making representations about the energy
efficiency of its CES multi-blower products, for compliance, marketing,
or other purposes, Cascade must fairly disclose the results of testing
under the DOE test procedure, as modified by the alternate test
procedure in this waiver.
(4) This waiver shall remain in effect from the date of issuance of
this Decision and Order until the effective date of a DOE final rule
prescribing amended test procedures appropriate to the above model
series manufactured by Cascade.
(5) This waiver is conditioned upon the presumed validity of
statements, representations, and documentary materials provided by the
petitioner. This waiver may be revoked or modified at any time upon a
determination that the factual basis underlying the Petition for Waiver
is incorrect, or DOE determines that the results from the alternate
test procedure are unrepresentative of the basic model's true energy
consumption characteristics.
Issued in Washington, DC, on August 8, 2008.
