### Background

Today's notice proposes to add test procedure amendments that are specific
to a new productdeSign-externally vented refrigerators and externally vented refrigerator-freezers. These test procedure amendmentswill apply only
to this productdesign and will not applyto existing productdeSigns of refrigerators and refrigerator-freezers without this feature. Existing test procedures for non-externallyvented refrigerators and refrigerator-freezers will remain unchanged. The energy conservation standards for refrigerators and refrigerator-freezers will be unaffected by the adoption or use ofthe proposed new test procedures.

The Department does notbelieve that any ofthe proposed changes to the test procedureswould alterthe
measurement ofenergyconsumption of electric refrigerators and refrigeratorfreezers currentlyon the market. Accordingly. adoption ofthe proposed amended test procedureswould not require any change in energy conservation standards for refrigerators and refrigerator-freezers currently in place. In addition. the Department believes thatthe proposed test procedure amendments would have no effect on the pending rule making considering revised minimumenergy conservation standards for electric

On March 14, 1995, Edward Schulak Equities, Inc. ("ESE") submitted a letter
to the Department regarding the inapplicabilityofexistingtest procedures in Appendix Al to externallyvented refrigerators. ESE submitted a description ofan externally vented refrigerator from a recently granted patent. ESE claimed that allowing cooleroutside air to be passed

room temperature. Based on the information submitted, the Department agrees that the existing test procedures do not permit the measurement of
energy consumption ofan externally vented refrigerator.

While ESE's letterwas submitted as a petition for waiver, the Department concluded that itswaiverprocesswas· notappropriate because waivers apply
to "basic models," and no models are currentlybeingmanufactured incorporatingthis invention, nor isthe invention being produced for retrofitting. Therefore, the Department published ESE's letterand issued a Notice ofInquiry inviting public

### FR 37604. No public commentswere received in response to this Notice of Inquiry.

OnNovember 13, 1995, acting upon the Department's suggestion, ESE submitted a draft ofproposed amendments to the test procedures for refrigerators and refrigerator-freezers. The Department referred this submittal
to the National Institute ofStandards and Technology (NIST). NIST, the Department and ESE representatives extensively discussed the requirements for test procedures for externallyvented refrigerators and refrigerator-freezers. NIST conducted an analysis oftest procedures for externallyvented refrigerators and refrigerator-freezers. The notice published today bythe Department reflects these extensive discussions and subsequent NIST recommendations for test procedure amendments. Today's notice proposes revising the
testprocedures for electric refrigerators and electric refrigerator-freezers appearing in 10 

### CFR Part 430, Subpart B, AppendixAl by: (1) Adding a definition ofexternallyvented refrigerators and refrigerator-freezers to which the revisions are applicable, (2) prescribing test conditions for externally vented refrigerators and refrigeratorfreezers, (3) specifyingenergy consumption measurement tests for externallyvented refrigerators and refrigerator-freezers, and (4) including calculation methods for derivingresults from test measurements.


### II. Discussion

The currenttest proceduresfor refrigerators and refrigerator-freezers, found at 10 

### CFR Part 430, AppendixAl ofSubpartB, does not address testing of externallyvented refrigerators and refrigerator-freezers. The existing test procedures applyto a refrigerator system to whichcool outside air cannot be conducted for purposes ofheat transfer. Externally vented refrigerators would be designed to permitoutside air
to be introduced across the refrigerator's condenser and compressor and. in some cases, throughoutthe walls ofthe refrigerator. The introduction ofoutside air at temperatures lowerthan the ambient room airtemperature permits

more efficient heattransfer, potentially resulting inenergy savings.

The Departmenttherefore proposesto revise the testprocedures to include provisions tailored to measuringthe energyconsumption ofexternally vented refrigerators and refrigeratorfreezers. These provisionswill add to, rather than replace, the existingtest procedures, which remain fully applicable to both externallyvented and non-vented refrigerators and refrigerator-freezers. The Department emphasizes thatthe proposed amendments to the test procedures do
not affect in any waythe test procedures applicable to existingrefrigerator designs. The amendments provide a method for accurately measuringthe energyconsumption ofan enclosed, externallyvented refrigeratoror refrigerator-freezer unit and take
account ofdesign features (e.g., enclosed condenser, outside air conduits. dampers) peculiarto an externallyvented refrigerator or refrigerator-freezer that circulates outside air around its condenser. The amendments do not apply to refrigerators or refrigerator-freezers that

use outside airthrough the refrigerator walls. With these amendments. the test procedureswill provide a basis for making comparable measurements of energyconsumption for externally vented and unvented refrigerators and refrigerator-freezers.

The Department also emphasizes that recognition ofa design option of externallyvented refrigerators and refrigerator-freezers does not affect in any way the Department's consideration ofdesign options in connection with its consideration ofproposed revisionsto energyconsumption standards for refrigerators and refrigerator-freezers. This design option was not included in the standards rulemaking record and therefore cannot be considered in the
current standards rulemaking.

The Department invites commentson any aspect ofthe proposed test procedure amendmentsfor externally vented refrigerators and refrigeratorfreezers.

The Departmenttodayproposes to amend the testprocedures applicable to electric refrigerators and electric refrigerator-freezers (10 

### CFR Part 430, Subpart B, Appendix AI), as follows:

test procedureswill apply onlyunder conditions where the externallyvented refrigeratoror refrigerator-freezer design is capable ofmixing the exterior air drawn in from outside the building envelopewith the ambient room air.

Airtemperature will also be measured atthe exterior air source. Temperature measurements are to be made at prescribed intervals.



### 3. Airducts. Externallyvented refrigerators and refrigerator/freezers depend upon air ducts to transfer exterior airto the refrigerator cabinet. Rather than specifyingthe length, diameter, shape and material ofthe duct, the Department proposes to specify airpressure requirements as a uniform test condition (section 2.6.3). Specifically, the proposed test procedures require exterior airpressure at the inlet to the refrigerator unit to be maintained at a negative pressure of 0.20"

### ±0.05"water column (62 Pa 

### ± 12.5 Pal. The testprocedures also specify location distances for the
pressure sensors, relative to the exterior air source (Le., the inlet to the building envelope) and to the condenser inlet.



### 4. Applicabilityof

### general testmethod conditions. The proposed amendments
to the test procedures are not intended
to supplantexisting test methods applicable to all otherrefrigerators and refrigerator-freezers. Accordingly, the proposed amendments provide that, except as expressly modified, the test conditions and specifications included in the existing test procedures shall also apply to externallyvented refrigerators and refrigerator-freezers (section 5.4).



### 5. Energy consumption correction factorfor testmeasurements. The Departmentproposes a seriesof formulas for determiningenergy consumption from test measurements. First, the Department recognizes that energyconsumption ofany refrigerator will be different with and without door openings. Under the existing test procedure, refrigerators are tested at 90 OF without door openingsto simulate the energyconsumption they would have at normal room temperature with door openings. Normal room temperature for the refrigerator test procedure is considered to be 80 OF, the typical temperature ofthe ambient air surroundingthe refrigerator's condenser. An externallyvented refrigerator will show an artificially low energyconsumption compared to an unvented refrigeratorwhen tested at 90 OF room airtemperature, because 90 OF is warmerthan normal room temperature. The Department proposes to require calculation ofa correction factor for each basic model ofexternally vented refrigerator. The correction factor is the ratio ofthe energyconsumption ofan externallyvented refrigerator (with external venting disabled) at 90 OF inlet air temperature to the energy consumption ofthe unit at 80 OF inlet airtemperature (sections 5.4.2.1 and 6.3.1).



### 6. Energyconsumption test measurementsandcalculations. Based

on analysis by NIST and itsderivation ofan algebraic equation for determining
energyconsumption over·a range of outside airtemperatures, the Department has determined that test measurements ofenergyconsumption need be taken at only two outside air temperatures, 90 OF and 60 OF (sections 5.4.2.2 and 5.4.2.3). Ifthe outside air temperature is not in this range, mixing controls and dampers will keep the condenser inlettemperature within the range. Accordingly, the Department proposes an energyprofileequation that will allow for the interpolation of energyconsumption at outside air temperatures within this range (section 6.3.4). The parametersofthe energy profile equation are determined for each basic model ofexternallyvented refrigerator that is tested, based on the measured energyconsumption during testingat 90 OF and 60 of.

Once the parametersofthe energy profile equation are determined, the test procedures provide a basis for calculatingenergyconsumption at varioustemperatures. Because temperatures vary across the country, throughout a day, and throughout the year, the proposed test procedures specify an energyconsumption formula that determines a unit's total energy consumption based on weighted averaging ofthe unit's energy consumption at different exterior air temperatures. Thetest procedures provideweighting factors for a national average energyconsumption (section 6.3.6) and weighting factors for four differentregions ofthe country, which

are identified on a map. This procedure

wasbased on the test procedure for heat pumps, for whichenergy savings are also a function ofclimate. The regional map is the same as that used in the heat pump test procedure, except Regions I and II from the heat pump test procedure are combined and called Region I. Externallyvented refrigerators need onlybe tested at 90 OF and 60 OF, and from such measurements, application ofthe correction factor, and application ofthe energy profile equation, the unit's average percycle
energy consumption can be determined for the nation as a whole and for each ofthe four regions ofthe country. The Departmentrecognizes the Federal Trade Commission (FTC) has authority
to prescribe labelingrequirements for all types ofrefrigerators and othercovered products and may require fact sheets containingregional performance information. The proposed energy consumption measurementformulas would satisfy the FTC's requirements.



### 7. Reportingrequirements. The Department is proposingto add a reportingrequirement for externally vented refrigerators and refrigeratorfreezers. Theenergy savings due to externallyventinga refrigerator or refrigerator-freezer is a function ofthe outdoor airtemperature, therefore, externallyvented refrigerators and refrigerator-freezer's energy use will depend on climate. The Department proposes to require that a manufacturer'scertification report include the national average annual energy use for externallyvented refrigerators and refrigerator-freezers. Separate reporting ofregional per cycle energyconsumption would not be required.
III. Review

### IV. Regulatory Review

Today's regulatory proposal has been determined not to be a "significant regulatory action" under Executive Order 12866, "RegulatoryPlanning and Review," (58 FR 51735, October4. 1993). Accordingly. today's action was not subject to review under the Executive Orderbythe Office of Information and Regulatory Affairs.



### V. Regulatory Flexibility Review

The proposed rule has been reviewed underthe Regulatory FlexibilityAct. Pub. L. 96-354 (42 U.s.C. 601-612) which requires preparation ofa regulatory flexibility analysis for any regulation that will have a Significant economic impact on a substantial number ofsmall entities. i.e

. jurisdictions. The proposed rule would
not have Significant economic impacton manufacturers ofexternallyvented refrigerators and refrigerator-freezers. The rule. ifpromulgated. would modify the testing methods that currently apply. DOE accordinglycertifies that the proposed rule would not. if promulgated. have a Significant economic impacton a substantial number ofsmall entities and that preparation ofa regulatory flexibility analysis is not warranted.



### VI. "Takings"Assessment Review

It has been determined pursuant to Executive Order 12630 (52 FR 8859. March 18. 1988) that this proposed regulation. ifadopted, would notresult in anytakings which might require compensation underthe Fifth Amendment to the United States Constitution.



### VII. Federalism Review

Executive Order 12612 (52 FR 41685. October 30. 1987) requires that regulations or rules be reviewed for any substantial direct effects on States. on the relationship between the Federal Government and the States. oron the distribution ofpower and responsibilities among various levels of Government. Ifthere are sufficient substantial direct effects. the Executive Order 12612 requires the preparation of

a Federalism assessmentto be used in decisions by seniorpolicy makers in promulgating or implementingthe regulation. The proposed rule published today would not alter the distribution of authority and responsibility to regulate in this area. The proposed rule would only revise a currently applicable DOE
test procedure to accommodate a technological development in the manufacture ofrefrigerators and refrigerator-freezers. Accordingly. DOE has determined that preparation ofa federalism assessment is unnecessary.

IX. Review UnderUnfunded Mandates Reform Act of 1995

Section 202 ofthe Unfunded Mandates Reform Act of 1995 ("Unfunded Mandates Act") requires that the Department prepare a budgetary impact statementbefore promulgatinga rule that includes a Federal mandate that may result in expenditure by state. local. and tribal governments. in the aggregate. orby the private sector. of $100 million or more in anyoneyear. The budgetary impact statement must include: (i) Identification ofthe Federal law under which the rule is promulgated; (ii) a qualitative and quantitative assessment ofanticipated
costs and benefits ofthe Federal mandate and an analYSis ofthe extent to which such costs to state. local. and tribal governments may be paid with Federal financial assistance; (iii) if feasible. estimates ofthe future compliance costs and ofany disproportionate budgetaryeffects the mandate has on particularregions. communities. non-Federal units of government. or sectors ofthe economy; (iv) iffeasible. estimatesofthe effect on the national economy; and (v) a description ofthe Department's prior consultation with elected representatives ofstate. local, and tribal governments and a summary and evaluation ofthe comments and

concerns presented.

The Departmenthas determined that the action proposed today does not include a Federal mandate that may result in estimated costsof$100 million

ormore to state. local or to tribal governments in the aggregate orto the private sector. Therefore. the requirements ofSections 203 and 204 of the Unfunded MandatesAct do not applyto this action.



### X. Review UnderExecutive Order 12988, "CivilJustice Reform"

With respect to the review ofexisting regulations and the promulgation of new regulations. Section 3(a) of Executive Order 12988. "CivilJustice Reform." 61 FR 4729 (February 7. 1996). imposeson executive agencies the general duty to adhere to the follOWing requirements: (1) Eliminate drafting

errors and ambiguity; (2) write regulations to minimize litigation; and (3) provide a clear legal standard for affected conductrather than a general standard and promote Simplification and burden reduction. With regard to the review required by Section 3(a). Section 3(b) ofthe Executive Order specificallyrequires that Executive agencies make every reasonable effort to

ensure that the regulation: (1) Clearly specifies the preemptive effect. ifany; (2) clearly specifies any effect on existing Federal law or regulation; (3) provide a clear legal standard for affected conductwhile promoting simplification and burden reduction; (4) specifies the retroactive effect. ifany; (5) adequately defines key terms; and (6) addresses other important issues affecting clarity and general draftsmanship under anyguidelines issued bythe Attorney General. Section 3(c) ofthe Executive Orderrequires Executive agenCies to review regulations in light ofapplicable standards Section 3(a) and Section 3(b) to determine whether they are met or it is unreasonable to meet one or more of them. DOE reviewed today's proposed rulemakingunderthe standards of Section 3 ofthe Executive Order and determined that. to the extent permitted by law. they meet the requirements of those standards.
