Decision and Order

In the Matter of: Fujitsu General Limited (Fujitsu) (Case No. CAC-039).

I. Background and Authority

Title III, Part C of the Energy Policy and Conservation Act of 1975 (EPCA), Pub. L. 94-163 (42 U.S.C. 6311-6317), established the Energy Conservation Program for certain industrial equipment, which includes commercial air conditioning equipment, the focus of this decision and order. (1) Part C specifically includes definitions (42 U.S.C. 6311), test procedures (42 U.S.C. 6314), labeling provisions (42 U.S.C. 6315), energy conservation standards (42 U.S.C. 6313), and the authority to require information and reports from manufacturers (42 U.S.C. 6316). With respect to test procedures, Part C authorizes the Secretary of Energy (the Secretary) to prescribe test procedures that are reasonably designed to produce results that measure 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 Standard 90.1 and in effect on June 30, 1992.” (42 U.S.C. 6314(a)(4)(A)) If the industry test procedure for commercial package air-conditioning and heating equipment is amended, EPCA directs the Secretary to amend the corresponding DOE test procedure 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). (42 U.S.C. 6314(a)(4)(B))

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. Table 1 to Title 10 of the Code of Federal Regulations (10 CFR) 431.96 directs manufacturers of commercial package air conditioning and heating equipment to use the appropriate procedure when measuring energy efficiency of this equipment. For commercial package air-source equipment with capacities between 65,000 and 760,000 Btu/h, ARI Standard 340/360-2004 is the applicable test procedure.

DOE's regulations for covered products and equipment permit a person to seek a waiver from the test procedure requirements for covered commercial equipment if at least one of the following conditions is met: (1) The petitioner's basic model contains one or more design characteristics that 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 as to provide materially inaccurate comparative data. 10 CFR 431.401(a)(1). Petitioners must include in their petition any alternate test procedures known to the petitioner to evaluate 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 according to the provisions of 10 CFR 431.401(g).

On December 16, 2011, Fujitsu submitted a petition for waiver from the DOE test procedure applicable to commercial package air-source and water-source central air conditioners and heat pumps set forth in 10 CFR 431.96. Fujitsu requested the waiver for specified basic model of Fujitsu AIRSTAGE V-II multi-split heat pump with a capacity of 264,000 Btu/h, and specified compatible indoor units. The applicable test procedure for these heat pumps is ARI 340/360-2004. Manufacturers are directed to use these test procedures pursuant to Table 1 of 10 CFR 431.96. Fujitsu seeks a waiver from the applicable test procedures under 10 CFR 431.96 on the grounds that its AIRSTAGE V-II multi-split heat pumps contain design characteristics that prevent testing according to the current DOE test procedures. Fujitsu requested that DOE allow it to test and rate its Airstage V-II multi-split heat pump with a capacity of 264,000 Btu/h, and specified compatible indoor units according to the American National Standards Institute (ANSI)/Air-conditioning, Heating and Refrigeration Institute (AHRI) Standard 1230-2010: Performance Rating of Variable Refrigerant Flow (VRF) Multi-Split Air-Conditioning and Heat Pump Equipment (AHRI 1230).

On May 16, 2012, DOE published a final rule (77 FR 28928) adopting American Society of Heating, Refrigerating, and Air-Conditioning Engineers (ASHRAE) Standard 90.1-2010 (ASHRAE final rule). The ASHRAE final rule incorporated by reference ANSI/AHRI 1230-2010 but omits sections 5.1.2 and 6.6 for the products addressed in this waiver request. The rule was effective on July 16, 2012 and requires use of the test procedure on or after May 13, 2013. This decision and order (D&O) requires Fujitsu to use ANSI/AHRI 1230-2010 as addressed in the DOE's May 16, 2012 final rule (77 FR 28928) to test and rate specified models in order to be consistent with future test procedure requirements.

II. Fujitsu's Petition for Waiver: Assertions and Determinations

In its December 16, 2011 petition, Fujitsu seeks a waiver from the applicable test procedures under 10 CFR 431.96 on the grounds that its AIRSTAGE V-II multi-split heat pumps contain design characteristics that prevent testing according to the current DOE test procedures. Specifically, Fujitsu asserts that the two primary factors that prevent testing of its AIRSTAGE V-II multi-split variable speed products are the same factors stated in the waivers that DOE granted to Mitsubishi Electric & Electronics America 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. See, e.g., 72 FR 17528 (April 9, 2007) (Mitsubishi); 76 FR 19069 (April 6, 2011) (Daikin); 76 FR 19078 (April 6, 2011) (Mitsubishi); 76 FR 31951 (June 2, 2011) (Carrier); 76 FR 50204 (August 12, 2011) (Fujitsu General Limited); 76 FR 65710 (October 24, 2011) (Mitsubishi).

The AIRSTAGE V-II systems have operational characteristics similar to the commercial multi-split products manufactured by other manufacturers. As indicated above, DOE has already granted waivers for these products. The AIRSTAGE V-II system consists of multiple indoor units connected to an air-cooled outdoor unit. These multi-splits are used in zoned systems where an outdoor or water-source unit can be connected with up to 45 separate indoor units, which need not be the same models. According to Fujitsu, the various indoor and outdoor models can be connected in a multitude of configurations, with many thousands of possible combinations. Consequently, Fujitsu requested that DOE grant a waiver from the applicable test procedures for its AIRSTAGE V-II product designs until a suitable test method is prescribed.

For the reasons discussed above, and because DOE prescribed ANSI/AHRI 1230 as the alternate test procedure in waivers granted to other manufacturers (including the grant of Fujitsu's interim waiver request (77 FR 13107, Mar. 5, 2012)), DOE determined that the equipment specified in Fujitsu's December 16, 2011 petition contains design characteristics that prevent testing according to the DOE test procedure, and that allowing Fujitsu to use as an alternate test procedure ANSI/AHRI 1230, as adopted in DOE's final rule dated May 16, 2012 (77 FR 28928), addresses these testing difficulties.

Consultations With Other Agencies

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