B. Background 

Today's notice proposes to add test 

procedure amendments that are specific 

to a new product deSign-externally

vented refrigerator-freezers. These test 

procedure amendments will apply only 

to this product design and will not 

apply to existing product deSigns of

procedures for non-externally vented 

refrigerators and refrigerator-freezers 

will remain unchanged. The energy 

conservation standards for refrigerators

unaffected by the adoption or use of the 

proposed new test procedures. 

The Department does not believe that 

any of the proposed changes to the test 

procedures would alter the 

measurement of energy consumption of 

electric refrigerators and refrigeratorfreezers currently on the market. 

Accordingly. adoption of the proposed 

amended test procedures would not

On March 14, 1995, Edward Schulak 

Equities, Inc. ("ESE") submitted a letter 

to the Department regarding the 

inapplicability of existing test 

procedures in Appendix Al to 

externally vented refrigerators. ESE 

submitted a description of an externally 

vented refrigerator from a recently 

granted patent. ESE claimed that

explained that the existing test

information submitted, the Department 

agrees that the existing test procedures 

do not permit the measurement of

concluded that its waiver process was·

On November 13, 1995, acting upon 

the Department's suggestion, ESE 

submitted a draft of proposed 

amendments to the test procedures for 

refrigerators and refrigerator-freezers. 

The Department referred this submittal 

to the National Institute of Standards 

and Technology (NIST). NIST, the 

Department and ESE representatives 

extensively discussed the requirements 

for test procedures for externally vented 

refrigerators and refrigerator-freezers. 

NIST conducted an analysis of test 

procedures for externally vented 

refrigerators and refrigerator-freezers. 

The notice published today by the 

Department reflects these extensive 

discussions and subsequent NIST 

recommendations for test procedure 

amendments. 

Today's notice proposes revising the 

test procedures for electric refrigerators 

and electric refrigerator-freezers 

appearing in 10 CFR Part 430, Subpart 

B, Appendix Al by: (1) Adding a 

definition of externally vented 

refrigerators and refrigerator-freezers to 

which the revisions are applicable, (2) 

prescribing test conditions for externally 

vented refrigerators and refrigeratorfreezers, (3) specifying energy 

consumption measurement tests for 

externally vented refrigerators and 

refrigerator-freezers, and (4) including 

calculation methods for deriving results 

from test measurements. 

II. Discussion 

The current test procedures for 

refrigerators and refrigerator-freezers, 

found at 10 CFR Part 430, Appendix Al 

of Subpart B, does not address testing of 

externally vented refrigerators and 

refrigerator-freezers. The existing test 

procedures apply to a refrigerator 

system to which cool outside air cannot 

be conducted for purposes of heat 

transfer. Externally vented refrigerators 

would be designed to permit outside air 

to be introduced across the refrigerator's 

condenser and compressor and. in some 

cases, throughout the walls of the 

refrigerator. The introduction of outside 

air at temperatures lower than the 

ambient room air temperature permits 

more efficient heat transfer, potentially 

resulting in energy savings. 

The Department therefore proposes to 

revise the test procedures to include 

provisions tailored to measuring the 

energy consumption of externally 

vented refrigerators and refrigeratorfreezers. These provisions will add to, 

rather than replace, the existing test 

procedures, which remain fully 

applicable to both externally vented and 

non-vented refrigerators and 

refrigerator-freezers. The Department 

emphasizes that the proposed 

amendments to the test procedures do 

not affect in any way the test procedures 

applicable to existing refrigerator 

designs. The amendments provide a 

method for accurately measuring the 

energy consumption of an enclosed, 

externally vented refrigerator or 

refrigerator-freezer unit and take 

account of design features (e.g., 

enclosed condenser, outside air 

conduits. dampers) peculiar to an 

externally vented refrigerator or 

refrigerator-freezer that circulates 

outside air around its condenser. The 

amendments do not apply to 

refrigerators or refrigerator-freezers that 

use outside air through the refrigerator 

walls. With these amendments. the test 

procedures will provide a basis for 

making comparable measurements of 

energy consumption for externally 

vented and unvented refrigerators and 

refrigerator-freezers. 

The Department also emphasizes that 

recognition of a design option of 

externally vented refrigerators and 

refrigerator-freezers does not affect in 

any way the Department's consideration 

of design options in connection with its 

consideration of proposed revisions to 

energy consumption standards for 

refrigerators and refrigerator-freezers. 

This design option was not included in 

the standards rule making record and 

therefore cannot be considered in the 

current standards rulemaking. 

The Department invites comments on 

any aspect of the proposed test 

procedure amendments for externally 

vented refrigerators and refrigeratorfreezers. 

The Department today proposes to 

amend the test procedures applicable to 

electric refrigerators and electric 

refrigerator-freezers (10 CFR Part 430, 

Subpart B, Appendix AI), as follows: 

1. Definitions and applicability of 

amended test procedures. The 

Department proposes to define 

"externally vented refrigerator or 

refrigerator-freezer" as a refrigerator or 

refrigerator-freezer with an enclosed 

condenser or an enclosed condenser! 

compressor compartment, and a set of 

air ducts for transferring exterior air 

from outside the building envelope into, 

through, and out of the refrigerator or 

refrigerator-freezer cabinet (section 

1.12). Energy consumption savings from 

an externally vented refrigerator or 

refrigerator-freezer should be achievable 

for outside air temperatures between 60 

OF and 80 OF. Above 80 OF, outside air 

may be warmer than ambient room air, 

making heat transfer in the wrong 

direction for energy savings. Below 60 

OF, outside air may be too cool for 

optimal operation of the unit. The 

proposed amendments to the test 

procedures are generally predicated 

upon a unit's design that permits the 

exclusion and/or mixing of outside air 

that is either above 80 OF or below 60 

OF. Accordingly, the amendments to the 

test procedures will apply only under 

conditions where the externally vented 

refrigerator or refrigerator-freezer design 

is capable of mixing the exterior air 

drawn in from outside the building 

envelope with the ambient room air. 

The modification includes 

thermostatically controlled dampers or 

controls that: 1) enable the proper 

mixing of outside and ambient room air 

when the outside air temperature is 

lower than 60 OF, and 2) exclude outside 

air warmer than 80 OF, or warmer than 

room air temperature (section 1.12).

temperature controls that exclude 

outside air either at a pre-set 

temperature no lower than 80 of or 

when the outside air temperature 

exceeds the ambient room air 

temperature (section 1.12). The test 

procedures require that prior to 

conducting energy consumption tests, 

the operability of thermostatic controls 

be verified (section 5.4.1). All tests must 

generally be conducted with the 

thermostatic controls operable. A 

special rule is provided for testing 

energy consumption when mixing 

controls do not operate properly 

(section 5.4.2.4). The test procedures 

will take account of the energy 

consumption of any exterior air fan that 

draws air to the refrigerator cabinet. 

2. Exterior air source. The Department 

recognizes that actual testing should 

take place under conditions of variable 

exterior air temperatures and, therefore, 

proposes to require that prescribed test 

conditions include the provision of an 

external air source that provides air at 

adjustable temperature and pressure 

capabilities (section 2.6). The test 

procedures prescribe the location of 

temperature sensors for measuring the 

air temperature at the inlet to the 

condenser/compressor compartment 

(section 2.6.2). Air temperature will also 

be measured at the exterior air source. 

Temperature measurements are to be 

made at prescribed intervals. 

3. Air ducts. Externally vented 

refrigerators and refrigerator/freezers 

depend upon air ducts to transfer 

exterior air to the refrigerator cabinet. 

Rather than specifying the length, 

diameter, shape and material of the 

duct, the Department proposes to 

specify air pressure requirements as a 

uniform test condition (section 2.6.3). 

Specifically, the proposed test 

procedures require exterior air pressure 

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 test procedures 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. Applicability of general test method 

conditions. The proposed amendments 

to the test procedures are not intended 

to supplant existing test methods 

applicable to all other refrigerators 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 externally vented refrigerators 

and refrigerator-freezers (section 5.4). 

5. Energy consumption correction 

factor for test measurements. The 

Department proposes a series of 

formulas for determining energy 

consumption from test measurements. 

First, the Department recognizes that 

energy consumption of any refrigerator 

will be different with and without door 

openings. Under the existing test 

procedure, refrigerators are tested at 90 

OF without door openings to simulate 

the energy consumption 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 of the ambient air 

surrounding the refrigerator's 

condenser. An externally vented 

refrigerator will show an artificially low 

energy consumption compared to an 

unvented refrigerator when tested at 90 

OF room air temperature, because 90 OF 

is warmer than normal room 

temperature. The Department proposes 

to require calculation of a correction 

factor for each basic model of externally 

vented refrigerator. The correction factor 

is the ratio of the energy consumption 

of an externally vented refrigerator (with 

external venting disabled) at 90 OF inlet 

air temperature to the energy 

consumption of the unit at 80 OF inlet 

air temperature (sections 5.4.2.1 and 

6.3.1). 

6. Energy consumption test 

measurements and calculations. Based 

on analysis by NIST and its derivation 

of an algebraic equation for determining 

energy consumption over· a range of 

outside air temperatures, the 

Department has determined that test 

measurements of energy consumption 

need be taken at only two outside air 

temperatures, 90 OF and 60 OF (sections 

5.4.2.2 and 5.4.2.3). If the outside air 

temperature is not in this range, mixing 

controls and dampers will keep the 

condenser inlet temperature within the 

range. Accordingly, the Department 

proposes an energy profile equation that 

will allow for the interpolation of 

energy consumption at outside air 

temperatures within this range (section 

6.3.4). The parameters of the energy 

profile equation are determined for each 

basic model of externally vented 

refrigerator that is tested, based on the 

measured energy consumption during 

testing at 90 OF and 60 of. 

Once the parameters of the energy 

profile equation are determined, the test 

procedures provide a basis for 

calculating energy consumption at 

various temperatures. Because 

temperatures vary across the country, 

throughout a day, and throughout the 

year, the proposed test procedures 

specify an energy consumption formula 

that determines a unit's total energy 

consumption based on weighted 

averaging of the unit's energy 

consumption at different exterior air 

temperatures. The test procedures 

provide weighting factors for a national 

average energy consumption (section 

6.3.6) and weighting factors for four 

different regions of the country, which 

are identified on a map. This procedure 

was based on the test procedure for heat 

pumps, for which energy savings are 

also a function of climate. 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. Externally vented refrigerators 

need only be tested at 90 OF and 60 OF, 

and from such measurements, 

application of the correction factor, and 

application of the energy profile 

equation, the unit's average per cycle 

energy consumption can be determined 

for the nation as a whole and for each 

of the four regions of the country. The 

Department recognizes the Federal 

Trade Commission (FTC) has authority 

to prescribe labeling requirements for all 

types of refrigerators and other covered 

products and may require fact sheets 

containing regional performance 

information. The proposed energy 

consumption measurement formulas 

would satisfy the FTC's requirements. 

7. Reporting requirements. The 

Department is proposing to add a 

reporting requirement for externally 

vented refrigerators and refrigeratorfreezers. The energy savings due to 

externally venting a refrigerator or 

refrigerator-freezer is a function of the 

outdoor air temperature, therefore, 

externally vented refrigerators and 

refrigerator-freezer's energy use will 

depend on climate. The Department 

proposes to require that a 

manufacturer's certification report 

include the national average annual 

energy use for externally vented 

refrigerators and refrigerator-freezers. 

Separate reporting of regional per cycle 

energy consumption would not be 

required. 

III. Review Under the National 

Environmental Policy Act of 1969 

In this rule, the Department proposes 

amendments to the test procedures for 

refrigerators and refrigerator-freezers to 

include externally vented refrigerators 

and refrigerator-freezers. The 

Department has determined that this 

. rule is covered under the Categorical 

Exclusion found at paragraph A.6 of 

appendix A to Subpart D, 10 CFR Part 

1021, which applies to the 

establishment of procedural 

rulemakings. This Proposed Rule is also

VI. "Takings" Assessment Review 

It has been determined pursuant to 

Executive Order 12630 (52 FR 8859.

substantial direct effects on States. on 

the relationship between the Federal 

Government and the States. or on the 

distribution of power and 

responsibilities among various levels of 

Government. If there are sufficient 

substantial direct effects. the Executive 

Order 12612 requires the preparation of 

a Federalism assessment to be used in 

decisions by senior policy makers in 

promulgating or implementing the 

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 of refrigerators and 

refrigerator-freezers. Accordingly. DOE 

has determined that preparation of a 

federalism assessment is unnecessary. 

VIII. Paperwork Reduction Act Review

The Department has determined that 

the action proposed today does not 

include a Federal mandate that may 

result in estimated costs of $100 million 

or more to state. local or to tribal 

governments in the aggregate or to the 

private sector. Therefore. the 

requirements of Sections 203 and 204 of

apply to this action. 

X. Review Under Executive Order 

12988, "Civil Justice Reform" 

With respect to the review of existing 

regulations and the promulgation of 

new regulations. Section 3(a) of 

Executive Order 12988. "Civil Justice 

Reform." 61 FR 4729 (February 7. 1996). 

imposes on 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 conduct rather than a general 

standard and promote Simplification 

and burden reduction. With regard to 

the review required by Section 3(a). 

Section 3(b) of the Executive Order 

specifically requires that Executive 

agencies make every reasonable effort to 

ensure that the regulation: (1) Clearly 

specifies the preemptive effect. if any; 

(2) clearly specifies any effect on 

existing Federal law or regulation; (3) 

provide a clear legal standard for 

affected conduct while promoting 

simplification and burden reduction; (4) 

specifies the retroactive effect. if any; (5) 

adequately defines key terms; and (6) 

addresses other important issues 

affecting clarity and general 

draftsmanship under any guidelines 

issued by the Attorney General. Section 

3(c) of the Executive Order requires 

Executive agenCies to review regulations 

in light of applicable 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 

rulemaking under the standards of 

Section 3 of the Executive Order and 

determined that. to the extent permitted 

by law. they meet the requirements of 

those standards.

B. Issues for Public Comment 

The Department of Energy is 

interested in receiving comments and 

data concerning the suitability and 

workability of these test procedures. 

Also, the Department welcomes 

comment on improvements or 

alternatives to these approaches. In 

particular, DOE is interested in 

gathering comments on the following: 

• The appropriateness of providing 

test procedures for externally vented 

refrigerators and refrigerator-freezers. 

• The definition of externally vented 

refrigerators and refrigerator-freezers 

and the applicability of the proposed 

revisions of the test procedures. 

• The interaction of the externally 

vented refrigerator and refrigerator/ 

freezer and its associated air conduits 

and building envelope penetration with 

the building heating and cooling loads. 

• The effects on energy conservation 

if externally vented refrigerators and 

refrigerator-freezers are installed 

without the outside air connection, and 

methods for adjusting the test results to 

account for the likely failure of some 

consumers to make use of this feature. 

• The appropriate test conditions fof 

externally vented refrigerators and 

refrigerator-freezers. including the 

selection of outside air temperatures at 

which testing should occur. 

• The appropriateness of the 

correction factor to account for the 

externally vented refrigerator and 

refrigerator-freezer's testing advantage 

resulting from the gO°F test temperature. 

• The appropriateness of the energy 

profile equations and the derivation of 

formulas for computing energy 

consumption from test results. 

• The appropriateness and means of 

measuring national and regional average 

per cycle energy consumption.

5.4.2.1 Correction factor test. To enable 

calculation of a correction factor, K. two full 

cycle tests shall be conducted to measure 

energy consumption of the unit with air 

mixing controls disabled and the condenser 

inlet air temperatures set at 90 of (32.2 °e) 

and 80 of (26.7 °e). Both tests shall be 

conducted with all compartment temperature 

controls set at the position midway between 

their warmest and coldest settings and the 

anti-sweat heater switch off. Record the 

energy consumptions eC9(' and eCHO, in kWh/ 

day. 

5.4.2.2 Energy consumption at 90 ° F. The 

unit shall be tested at 90 OF (32.2 0c) exterior 

air temperature to record the energy 

consumptions (e9(')' in kWh/day. For a given 

setting of the anti-sweat heater, i corresponds 

to each of the two states of the compartment 

temperature control positions. 

5.4.2.3 Energy consumption at 60 oF. The 

unit shall be tested at 60 OF (26.7 °e) exterior 

air temperature to record the energy 

consumptions (e60); in kWh/day. For a given 

setting of the anti-sweat heater, i corresponds 

to each of the two states of the compartment 

temperature control positions. 

5.4.2.4 Energy consumption if mixing 

controls do not operate properly. If the 

operability of temperature and mixing 

controls has not been verified as required 

under section 5.4.1. the unit shall be tested 

at 50 OF (10.0 0c) and 30 OF ( - l.l 0c) exterior 

air temperatures to record the energy 

consumptions (eso), and (eoo);. For a given 

setting of the anti -sweat heater. i corresponds 

to each of the two states of the compartment 

temperature control positions.

setrings of compartment temperature 

controls. For a given setting of the anti-sweat 

heater, follow the calculation procedures of 

section 6.2 to combine the test results for 

energy consumption of the unit at different 

temperature control settings for each 

condenser inlet air temperature tested under 

sections 5.4.2.2. 5.4.2.3. and 5.4.2.4, where 

applicable, (e90)', (e60)', (eso)., and (e30);. The 

combined values are E90, E6Q. E,(). and E30, 

where applicable. in kWh/day. 

6.3.3 Energy consumption corrections. 

For a given setting of the anti-sweat heater. 

the energy consumptions E90. E6Q. Eso, and E30 

calculated in section 6.3.2 shall be adjusted 

by multiplying the correction factor K to 

obtain the corrected energy consumptions 

per day. in kWh/day: 

E90 = K X E90, 

E60 = K x E6Q, 

Eso = K X E50, and 

E30 = K X E30 

Where. 

K is determined under section 6.3.1. and EgO, 

E6Q, E,o. and E30 are determined under section 

6.3.2.

AGENCY: U.S. Environmental Protection 

Agency (USEP A). 

ACTION: Proposed rule. 

SUMMARY: The USEP A is proposing to 

approve the State Implementation Plan 

(SIP) revision request submitted by the 

Illinois Environmental Protection 

Agency (IEPA) on August 15. 1996. In 

the August 15 request, IEPA requested 

that the Marathon Oil Company in 

Robinson, Illinois be granted a carbon 

monoxide variance with specified 

conditions beginning]anuary 19.1996, 

and ending August 4, 1997. In the Final 

Rules section of this Federal Register, 

USEPA is approving the State's SIP 

revision as a direct final rule without 

prior proposal because the agency views 

this as a noncontroversial SIP revision 

and anticipates no adverse comments. A 

detailed rationale for the approval is set 

forth in the direct final rule. If no 

adverse comments are received in 

response to this proposed rule, no 

further activity is contemplated in 

relation to this rule. If USEPA receives 

adverse comments, the direct final rule 

will be withdrawn and all public 

comments received will be addressed in 

a subsequent final rule based on this 

proposed rule. USEP A will not institute
