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).

Design Characteristics Constituting the Grounds for Petition
The United States Department of Energy has designated the American
Refrigeration Institute (ARI) as the body of air conditioning industry
partners to develop and maintain standards for compliance to the
National Appliance Energy Conservation Act of 1987 (NAECA). (10 CFR
430). The two standards that were developed by ARI 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
that the indoor blower-motor combinations can range from 2 to 8 indoor
blower-motors that are independently operating. Thus a waiver is sought
since the current procedures for testing do not apply.
This request for a waiver will include SEER calculations that are
the result of live data for a multi-indoor blower-motor configuration,
those specific procedures followed during the test, the data in the
test were conducted by the Texas A&M University Energy Services
[[Page 19902]]
Laboratory (TAMU-ESL) by Michael 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.
The ``Results of Heating and Cooling Performance Testing of Cascade
Energy SaverTM'' report from Texas A&M is attached in the
Appendix A.
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 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 \1/3\hp 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-the-shelf 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 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.

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 [deg]C (0.5
[deg]F) during steady state operations. Temperatures from 17 [deg]F
to 120 [deg]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.
Electric resistance heaters and chilled water coils are used to
maintain room 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.
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.
BILLING CODE 6450-01-P
[GRAPHIC] [TIFF OMITTED] TN20AP07.004
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 (dry-bulb, 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.

BILLING CODE 6450-01-C
The test procedure consisted of setting up the CES unit as per
manufacturer's recommendations, charging the system(s), installing
the appropriate instrumentation,
[[Page 19906]]
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.
