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 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).

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 blowermotor configuration, those specific procedures followed during the test, the data in the test were conducted by the Texas A&M University Energy Services E:\FR\FM\20APN1.SGM 20APN1 19902 Federal Register / Vol. 72, No. 76 / Friday, April 20, 2007 / Notices 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. sroberts on PROD1PC70 with NOTICES 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 VerDate Aug<31>2005 18:52 Apr 19, 2007 Jkt 211001 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 Frm 00027 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.

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.

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.

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

Identification of Basic Sizes and Models of CES

    The CES is sold in the following sizes and models:

    Example 1: Model CES 1-2-2-H-5kw is a size 2 Ton evaporative coil 
matched with a single 2 ton heat pump, with 2 blowers, horizontal 
configuration with 5 kW auxiliary heat.
    Example 2: Model CES 2-2.5-8-V-10kw is a size 6 ton 50/50 split 
evaporative coil matched with two 2.5 ton heat pumps, with 8 blowers, 
vertical upflow configuration with 10 kW auxiliary heat.

    Note: Table 1 below only shows horizontal configurations. There 
is not a difference in performance. A vertical unit could have been 
easily represented.
