SUPPLEMENTARY INFORMATION:

In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 431.401(f)(4), DOE is providing notice of the issuance of the Decision and Order set forth below. In this Decision and Order, DOE grants Sanyo a waiver from the existing DOE commercial package air conditioner and heat pump test procedures for its ECO-i multi-split products. The waiver requires Sanyo use the alternate test procedure provided in this notice to test and rate the specified models from its ECO-i multi-split product line (as identified below). The cooling capacities of Sanyo's commercial heat pump products at issue in the waiver petition filed by Sanyo range from 72,000 Btu/h to 288,000 Btu/h. All of the air-source Sanyo products are covered by this waiver. The Sanyo water-source products with capacities greater than or equal to 135,000 Btu/h are not covered by this waiver because the DOE test procedure only covers water-source heat pumps with capacities less than 135,000 Btu/h.

Today's decision prohibits Sanyo from making any representations concerning the energy efficiency of these products unless the product has been tested consistent with the provisions and restrictions in the alternate test procedure set forth in the Decision and Order below, and the representations fairly disclose the test results. (42 U.S.C. 6314(d)) Distributors, retailers, and private labelers are held to the same standard when making representations regarding the energy efficiency of these products. Id.

Decision and Order; In the Matter of: Sanyo North America Corp. (Sanyo) (Case No. CAC-027)

Background

Title III of the Energy Policy and Conservation Act (EPCA) sets forth a variety of provisions concerning energy efficiency, including Part A of Title III which establishes the “Energy Conservation Program for Consumer Products Other Than Automobiles.” (42 U.S.C. 6291-6309) Part A-1 of Title III provides for a similar energy efficiency program titled “Certain Industrial Equipment,” which includes large and small commercial air conditioning equipment, package boilers, storage water heaters, and other types of commercial equipment. (42 U.S.C. 6311-6317)

Today's notice involves commercial equipment under Part A-1. The statute specifically includes definitions (42 U.S.C. 6311), test procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C. 6315), and energy conservation standards (42 U.S.C. 6313). It also provides the Secretary of Energy (the Secretary) with the authority to require information and reports from manufacturers. (42 U.S.C. 6316) The statute authorizes the Secretary of Energy (the Secretary) to prescribe test procedures that are reasonably designed to produce test results that reflect energy efficiency, energy use, and estimated annual 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 [Illuminating Engineering Society] Standard 90.1 and in effect on June 30, 1992.” (42 U.S.C. 6314(a)(4)(A)) Under 42 U.S.C. 6314(a)(4)(B), the Secretary must amend the test procedure for a covered commercial product if the applicable industry test procedure is amended, unless the Secretary determines, by rule and based on clear and convincing evidence, that such a modified test procedure does not meet the statutory criteria set forth in 42 U.S.C. 6314(a)(2) and (3).

On December 8, 2006, DOE published a final rule adopting test procedures for commercial package air-conditioning and heating equipment, effective January 8, 2007. 71 FR 71340. DOE adopted the International Organization for Standardization (ISO) Standard 13256-1-1998, “Water-source heat pumps—Testing and rating for performance—Part 1: Water-to-air and brine-to-air heat pumps,” for small commercial package water-source heat pumps with capacities less than 135,000 British thermal units per hour (Btu/h). Id. at 71371. Pursuant to this rulemaking, DOE's regulations at 10 CFR 431.95(b)(3) incorporate by reference ISO Standard 13256-1-1998. In addition, Table 1 of 10 CFR 431.96 directs manufacturers of commercial package water-source air conditioning and heating equipment to use the appropriate procedure when measuring the energy efficiency of those products. For air-source heat pumps with capacities greater than 65,000 Btu/h, DOE adopted ARI Standard 340/360-2004.

In addition, DOE's regulations allow a person to seek a waiver for a particular basic model from the test procedure requirements for covered commercial equipment if: (1) That basic model contains one or more design characteristics which prevent testing according to the prescribed test procedures; or (2) the prescribed test procedures may evaluate the basic model in a manner so unrepresentative of its true energy consumption characteristics as to provide materially inaccurate comparative data. 10 CFR 431.401(a)(1). A waiver petition must include any alternate test procedures known to the petitioner to evaluate characteristics of the basic model in a manner representative of its energy consumption. 10 CFR 431.401(b)(1)(iii). The Assistant Secretary for Energy Efficiency and Renewable Energy (Assistant Secretary) may grant a waiver subject to conditions, including adherence to alternate test procedures. 10 CFR 431.401(f)(4). Waivers remain in effect pursuant to the provisions of 10 CFR 431.401(g).

The waiver process also allows any interested person who has submitted a petition for waiver to file an application for interim waiver from the applicable test procedure requirements. 10 CFR 431.401(a)(2). An interim waiver may be granted if the Assistant Secretary determines 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 if 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 431.401(e)(3). An interim waiver remains in effect for 180 days or until DOE issues its determination on the petition for waiver, whichever occurs first. The interim waiver may be extended by DOE for an additional 180 days. 10 CFR 431.401(e)(4).

On January 4, 2010, Sanyo filed a petition for waiver from the test procedures at 10 CFR 431.96 applicable to commercial package air and water-source central air conditioners and heat pumps, as well as an application for interim waiver. The cooling capacities of Sanyo's commercial ECO-i multi-split heat pump products at issue in the waiver petition range from 72,000 Btu/h to 288,000 Btu/h. The Sanyo products with capacities ≥ 135,000 Btu/h are not covered by this waiver because there is Start Printed Page 41847no DOE test procedure for water-source heat pumps with capacities ≥ 135,000 Btu/hr. The cooling capacities of Sanyo's commercial ECO-i air-source multi-split heat pump products also range from 72,000 Btu/h to 288,000 Btu/h. All of these products are covered by this waiver, as ARI Standard 340/360-2004 covers products with capacities greater than 65,000 Btu/h.

Sanyo seeks a waiver from the applicable test procedures under 10 CFR 431.96 on the grounds that its ECO-i multi-split heat pumps contain design characteristics that prevent testing according to the current DOE test procedures. Specifically, Sanyo asserts that the two primary factors that prevent testing of its multi-split variable speed products are the same factors stated in the waivers that DOE granted to Mitsubishi Electric & Electronics USA, Inc. (Mitsubishi) and other manufacturers for similar lines of commercial multi-split air-conditioning systems:

  • Testing laboratories cannot test products with so many indoor units; and
  • There are too many possible combinations of indoor and outdoor units to test. 69 FR 52660 (August 27, 2004) (Mitsubishi waiver); 72 FR 17528 (April 9, 2007) (Mitsubishi waiver); 72 FR 71387 (Dec. 17, 2007) (Samsung waiver); 72 FR 71383 (Dec. 17, 2007) (Fujitsu waiver); 73 FR 39680 (July 10, 2008) (Daikin waiver); 74 FR 15955 (April 8, 2009) (Daikin waiver); 74 FR 16193 (April 9, 2009) (Sanyo waiver); 74 FR 16373 (April 10, 2009) (Daikin waiver).

On March 18, 2010, DOE published Sanyo's petition for waiver in the Federal Register, seeking public comment pursuant to 10 CFR 431.401(b)(1)(iv), and granted the application for interim waiver. 75 FR 13114. DOE received no comments on the Sanyo petition.

In a similar case, DOE published a petition for waiver from Mitsubishi for products very similar to Sanyo's multi-split products. 71 FR 14858 (March 24, 2006). In the March 24, 2006, Federal Register notice, DOE also published and requested comment on an alternate test procedure for the MEUS products at issue. DOE stated that if it specified an alternate test procedure for MEUS in the subsequent Decision and Order, DOE would consider applying the same procedure to similar waivers for residential and commercial central air conditioners and heat pumps, including such products for which waivers had previously been granted. Id. at 14861. Comments were published along with the Mitsubishi Decision and Order in the Federal Register on April 9, 2007. 72 FR 17528. Most of the comments were favorable. One commenter indicated that a waiver was unnecessary. However, the commenter did not present a satisfactory method of testing the products. Id. at 72 FR 17529. Generally, commenters agreed that an alternate test procedure is necessary while a final test procedure for these types of products is being developed. Id. The Mitsubishi Decision and Order included the alternate test procedure adopted by DOE. Id. at 72 FR 17530.

Assertions and Determinations

Sanyo's Petition for Waiver

Sanyo seeks a waiver from the DOE test procedures for this product class on the grounds that its ECO-i multi-split heat pumps contain design characteristics that prevent them from being tested using the current DOE test procedures. As stated above, Sanyo asserts that the two primary factors that prevent testing of multi-split variable speed products, regardless of manufacturer, are the same factors stated in the waivers that DOE granted to Mitsubishi, Fujitsu General Ltd. (Fujitsu), Samsung Air Conditioning (Samsung), Daikin, and LG for similar lines of commercial multi-split air-conditioning systems: (1) Testing laboratories cannot test products with so many indoor units; and (2) there are too many possible combinations of indoor and outdoor unit to test.

The Sanyo ECO-i systems have operational characteristics similar to the commercial multi-split products manufactured by Mitsubishi, Samsung, Fujitsu, LG, and Daikin. As indicated above, DOE has granted waivers for these products. The ECO-i system includes 90 unique outdoor models and 54 unique indoor models, and can connect up to 40 indoor units to a single outdoor unit. There are over one million combinations possible with the Sanyo ECO-i system. Consequently, Sanyo requested that DOE grant a waiver from the applicable test procedures for its ECO-i product designs until a suitable test method can be prescribed. DOE believes that the Sanyo ECO-i equipment and equipment for which waivers have previously been granted are alike with respect to the factors that make them eligible for test procedure waivers. Therefore, DOE has decided to grant Sanyo a waiver for its ECO-i multi-split products, similar to the multi-split product waivers already issued to the other manufacturers mentioned above.

Previously, in addressing Mitsubishi's R410A CITY MULTI VRFZ products, which are similar to the Sanyo products at issue here, DOE stated:

To provide a test procedure from which manufacturers can make valid representations, the Department [DOE] is considering setting an alternate test procedure for MEUS [Mitsubishi] in the subsequent Decision and Order. Furthermore, if DOE specifies an alternate test procedure for MEUS, DOE is considering applying the alternate test procedure to similar waivers for residential and commercial central air conditioners and heat pumps. Such cases include Samsung's petition for its DVM products (70 FR 9629, February 28, 2005), Fujitsu's petition for its Airstage variable refrigerant flow (VRF) products (70 FR 5980, February 4, 2005), and MEUS's petition for its R22 CITY MULTI VRFZ products. (69 FR 52660, August 27, 2004).

(71 FR 14861, March 24, 2006).

Sanyo did not include an alternate test procedure in its petition for waiver. However, in response to two recent petitions for waiver from Mitsubishi, DOE specified an alternate test procedure that Mitsubishi could use to test and make valid energy efficiency representations for its R410A CITY MULTI products and its R22 multi-split products. Alternate test procedures related to the Mitsubishi petitions were published in the Federal Register on April 9, 2007 and December 15, 2009. 72 FR 17528; 74 FR 66311. DOE believes that the same alternate test procedure specified in the Mitsubishi decision could be used to test the Sanyo products at issue here.

DOE understands that existing testing facilities have a limited ability to test multiple indoor units simultaneously. It also understands that it is impractical to test some variable refrigerant flow zoned systems because of the number of possible combinations of indoor and outdoor units. DOE further notes that after the waiver granted for Mitsubishi's R22 multi-split products, AHRI formed a committee to develop a testing protocol for variable refrigerant flow systems. The committee developed AHRI Standard 1230-2009: “Performance Rating of Variable Refrigerant Flow (VRF) Multi-Split Air-Conditioning and Heat Pump Equipment.” AHRI adopted the standard in June 2009. AHRI 1230-2009 is substantially the same as DOE's alternate test procedure with respect to the testing of these Sanyo products. It has recently been adopted as an addendum to ASHRAE 90.1, and DOE plans to consider this industry standard in a subsequent test procedure rulemaking.

DOE issues today's Decision and Order granting Sanyo a test procedure waiver for its commercial ECO-i air-Start Printed Page 41848source and water-source multi-split heat pumps. As a condition of this waiver, Sanyo must use the alternate test procedure described below. This alternate test procedure is the same in all relevant particulars as the one that DOE applied to the Mitsubishi waiver.

Alternate Test Procedure

The alternate test procedure permits Sanyo to designate a “tested combination” for each model of outdoor unit. The indoor units designated as part of the tested combination must meet specific requirements. For example, the tested combination must have from two to five (for systems with nominal cooling capacities greater than 150,000 Btu/h, the number of indoor units may be as high as eight to be able to test non-ducted indoor unit combinations) indoor units so that it can be tested in available test facilities. The tested combination must be tested according to the applicable DOE test procedure, as modified by the provisions of the alternate test procedure as set forth below.

The alternate DOE test procedure also allows Sanyo to represent the products' energy efficiency. These representations must fairly disclose the test results. The DOE test procedure, as modified by the alternate test procedure set forth in this Decision and Order, provides for efficiency rating of a non-tested combination in one of two ways: (1) At an energy efficiency level determined using a DOE-approved alternative rating method; or (2) at the efficiency level of the tested combination utilizing the same outdoor unit.

As in the Mitsubishi waiver, DOE believes that allowing Sanyo to make energy efficiency representations for non-tested combinations by adopting the alternative test procedure is reasonable because the outdoor unit is the principal efficiency driver. The current DOE test procedure for commercial products tends to rate these products conservatively because it does not account for their multi-zoning feature. The multi-zoning feature of these products enables them to cool only those portions of the building that require cooling. Products with a multi-zoning feature are expected to use less energy than units controlled by a single thermostat, which cool the entire home or commercial building regardless of whether only portions need cooling. The multi-zoning feature would not be properly evaluated by the current test procedure, which requires full-load testing. Full-load testing requires the entire building to be cooled. Products using a multi-zoning feature and subjected to full-load testing would be at a disadvantage because they are optimized for highest efficiency when operating with less than full loads. The alternate test procedure will provide a conservative basis for assessing the energy efficiency of such products.

With regard to the laboratory testing of commercial products, some of the difficulties associated with the existing test procedure are avoided by the alternate test procedure's requirements for choosing the indoor units to be used in the manufacturer-specified tested combination. For example, in addition to limiting the number of indoor units, another requirement is that all the indoor units must be subjected the same minimum external static pressure. This requirement enables the test lab to manifold the outlets from each indoor unit into a common plenum that supplies air to a single airflow measuring apparatus. This eliminates situations in which some of the indoor units are ducted and some are non-ducted. Without this requirement, the laboratory must evaluate the capacity of a subgroup of indoor coils separately and then sum the separate capacities to obtain the overall system capacity. Measuring capacity in this way would require that the test laboratory be equipped with multiple airflow measuring apparatuses. It is unlikely that any test laboratory would be equipped with the necessary number of such apparatuses. Alternatively, the test laboratory could connect its one airflow measuring apparatus to one or more common indoor units until the contribution of each indoor unit had been measured. However, that approach would be so time-consuming as to be impractical.

Furthermore, DOE stated in the March 24, 2006 notice publishing the Mitsubishi petition for waiver that if it decided to specify an alternate test procedure for Mitsubishi, it would consider applying the procedure to waivers for similar residential and commercial central air conditioners and heat pumps produced by other manufacturers. 71 FR 14861. As noted above, most of the comments received by DOE in response to the March 2006 notice supported the proposed alternate test procedure. 72 FR 17528, 17529 (April 9, 2007). Commenters responding to that prior notice generally agreed that an alternate test procedure is appropriate for an interim period while a final test procedure for these products is being developed. Id.

For the reasons discussed above, DOE believes Sanyo's ECO-i multi-split products cannot be tested using the procedures prescribed in 10 CFR 431.96 (ISO Standard 13256-1 (1998) and ARI Standard 340/360-2004) and incorporated by reference in DOE's regulations at 10 CFR 431.95(b)(2)-(3). After careful consideration, DOE has decided to prescribe the alternate test procedure first developed for the Mitsubishi waiver for Sanyo's commercial multi-split products. The alternate test procedure for the Sanyo products must include the modifications described above.

Consultations With Other Agencies

DOE consulted with the Federal Trade Commission (FTC) staff concerning the Sanyo petition for waiver. The FTC staff did not have any objections to issuing a waiver to Sanyo.

Conclusion

After careful consideration of all the materials submitted by Sanyo, the absence of any comments, and consultation with the FTC staff, it is ordered that:

(1) The petition for waiver filed by Sanyo (Case No. CAC-027) is hereby granted as set forth in the paragraphs below.

(2) Sanyo shall not be required to test or rate its ECO-i multi-split air conditioner and heat pump models listed below on the basis of the test procedures cited in 10 CFR 431.96, specifically, ISO Standard 13256-1 (1998) and ARI Standard 340/360-2004 (incorporated by reference in 10 CFR 431.95(b)(2-3)). Instead, it shall be required to test and rate such products according to the alternate test procedure as set forth in paragraph (3).

(3) Alternate test procedure.

(A) Sanyo is required to test the products listed in paragraph (2) above according to the test procedure for commercial package air conditioners and heat pumps prescribed by DOE at 10 CFR 431.96 (ISO Standard 13256-1 (1998) and ARI Standard 340/360-2004 (incorporated by reference in 10 CFR 431.95(b)(2)-(3)), except that Sanyo shall test a tested combination selected in accordance with the provisions of subparagraph (3)(B) below. For every other system combination using the same outdoor unit as the tested combination, Sanyo shall make representations concerning the ECO-i products covered in this waiver according to the provisions of subparagraph (C) below.

(B) Tested combination. The term “tested combination” means a sample basic model comprised of units that are production units, or are representative of production units, of the basic model being tested. For the purposes of this waiver, the tested combination shall have the following features:

(i) The basic model of a variable refrigerant flow system used as a tested combination shall consist of one outdoor unit, with one or more compressors, that is matched with between two and five indoor units. (For systems with nominal cooling capacities greater than 150,000 Btu/h, as many as eight indoor units may be used, so as to be able to test non-ducted indoor unit combinations). For multi-split systems, each of these indoor units shall be designed for individual operation.

(ii) The indoor units shall:

(a) Represent the highest sales model family, or another indoor model family if the highest sales model family does not provide sufficient capacity (see (b) below);

(b) Together, have a nominal cooling capacity that is between 95 percent and 105 percent of the nominal cooling capacity of the outdoor unit;

(c) Not, individually, have a nominal cooling capacity greater than 50 percent of the nominal cooling capacity of the outdoor unit;

(d) Operate at fan speeds that are consistent with the manufacturer's specifications; and

(e) Be subject to the same minimum external static pressure requirement while being configurable to produce the same static pressure at the exit of each outlet plenum when manifolded as per section 2.4.1 of 10 CFR Part 430, Subpart B, Appendix M.

(C) Representations. In making representations about the energy efficiency of its ECO-i multi-split products, for compliance, marketing, or other purposes, Sanyo must fairly disclose the results of testing under the DOE test procedure in a manner consistent with the provisions outlined below:

(i) For ECO-i multi-split combinations tested in accordance with this alternate test procedure, Sanyo may make representations based on those test results.

(ii) For ECO-i multi-split combinations that are not tested, Sanyo may make representations based on the testing results for the tested combination and that are consistent with either of the two following methods:

(a) Representation of non-tested combinations according to an alternative rating method approved by DOE; or

(b) Representation of non-tested combinations at the same energy efficiency level as the tested combination with the same outdoor unit.

(4) This waiver shall remain in effect from the date this Decision and Order is issued, consistent with the provisions of 10 CFR 431.401(g).

(5) This waiver is issued on the condition that the statements, representations, and documentary materials provided by the petitioner are valid. DOE may revoke or modify the waiver at any time if it determines that the factual basis underlying the petition for waiver is incorrect, or the results from the alternate test procedure are unrepresentative of the basic models' true energy consumption characteristics.
