### The Federal Energy Administration <FEA> hereby amends Part 430, Chapter II of Title 10, Code ofFederal Regu- lations, in order 

### to prescribe test proce- dures for electric refrigerators, electric refrigerator-freezers, and freezers, 'pursuant to section 323 (42 

### u.s.c. 6293) of the Energy Policy and Conservation Act <Act> <Pub. L. 94-163). These test procedures were proposed by notice issued April 21, 1977 (42 FR21584, April 17, 1977)

, and a public hearing on the pro- posed test procedures was held on June 14, 1977. The definitions of "refrig- erator," "refrigerator-freezer," and "freezer" were proposed at 41 FR 19980, May 14, 1976, but these definitions have been revised in response 

### to public comments, as discussed below.

By notice issued May 24, 1977 <42 FR 27896, June 1, 1977>, FEA established Subparts A and B of Part 430, Chapter II of Title 10, Code of Federal Regula- tions. Certain definitions and general provisions applicable 

### to theEnergy Conservation Program For Appliances have been promulgated in Subpart A. Final 

### testprocedures forroom airconditioners and dishwashers have beenprescribed in Subpart B. In 

### addition 

### to the test pro- cedures for electricrefrigerators, electric refrigerator-freezers, and freezers pre- scribed today, the final test procedures for clothes dryers and television sets are also being prescribed byseparatenotices. Several other test procedures have been RULES AND REGULATIONS

B. DISCUSSION OF COMMEN'.l'S 

### Comments were received from industry
a trade association, and a state government. The major issues raised by the comments are illscussed below.

1, TYPE OF ENERGY INPUT 

### Commentswerereceived which pointed outthattheproposed definition of "basic model" for refrigerators and refrigera- tor-freezers referred 

### to "electrical characteristics" of covered products. These comments questioned whether units using a non-electrical energy input were intended to be

. covered by the proposed test procedures.

At the time of publication of the pro- posed test procedures, FEA believed that refrigerators and refrigerators-freezers using an energy source other than elee-- tricity were notto.any significant extent distributed in commerce. Subsequently FEA has learned thata significant number of gas refrigeration products are manufactured, primarily for use in 

### mobile homes and recreational vehicles, andtherefore itls asldng NBS to develop test procedures for these covered prod· ucts. ·

The test procedures prescribed today for electric refrigerators and electric refrigerator-freezers reflectminor edlt-0rlal and definitfonal changes which were necessary to clarify that these proce- dures apply only to electric refrigerators and electric refrigerator-freezers. This entailed redefining "refrigerator" and "refrigerator-freezer" and modifying the proposed definitions to apply only 

### to the class ofelectric refrigerators and electric refrigerator-freezers. Section 323 of the Act authorizes the development of test procedures for classes of a covered prod· ucttype. Test procedures for the class of gas refrigerators and gas refrigerator• freezers will be proposed 

### as soon 

### as practicable, in keeping with the notice issued July 22, 1976 (41 FR 31237, July 27, 1976) which delayed the proposal of test procedures for refrigerators and re• frigerator-freezers beyond the date con• templated by the Act.

Because FEA is 

### unaware of any 

### freezers intended for personal use or consumption which use an energy source other than electricity, it has not asked NBS to develop any additional test pro- cedures for freezers. 'Ilhe test proce- dures prescribed today for freezers, however, do reflect a minor definitional change to indicate that only electric freezers arepresentlyintended tobe covered by these test pr.ocedures.

2. ANNUAL OPERATING 

### cosr Severalcomments suggested that a 50- percentuse credit for an antisweatheater switch, such as the credit allowed in the energy factor calculations, also bc allowed in the estimated annual operat- ing cost calculations. FEA agrees that such an adjustment of the estimated annual operating cost calculations is· necessary if 

### the estimated annual op- erating cost figure is 

### to be logically consistent with the energy factor. Without the adjustment, two products which aro identical except for an antisweat heater switch on one would have the same annual operating cost figure, but the unit with the antisweat heater switch would have a lower energy factor. This would be confusing to consumers. Therefore, the estimated annual operating cost for electric refrigerators, electric refrigera- tor-freezers, and freezers has been amended in §§ 

### 430.22(a) CU and 430.22 Cb) (1) to**r~ect** 

### these changes.

One- comment stated that no credit should be applied either to the energy factor or to the cost of operation, because such a credit would be a disin· centive for manufacturers 

### to remove the**ne~.d** 

### for antisweat heaters (e.g., by improving the insulation of their products>. However, NBS has verified that the antisweat heater switch is indeed used when available in refrigeration

FEDERAL REGISTER, VOL. 42, NO. 178-WEDNESDAY, SEPTEMBER**1~,** 1977**~**

### pr6ducts, and that such products therefore use 

### less energy than similar 

### units without the switch. For these reasons, FEA 

### has determined that a. use credit for an antisweat heater switch is 

### ap- propriate both for the annual operating cost and for the energy faetor calcUlations. '

Several comments suggested that the

use credit should be a. :figure other than 50 percent, but no supporting information was supplied which :was not pre- viously considered in arriving at the 50 percentcreditrecommended by NBS and adopted by F.EA as 

### best reflecting actual

consumer use of antisweat }leaters.

One comment suggested that monthly operating cost be included as another

measure of energy consumption. FEA 

### does not believe that 

### a measure of monthly operating cost would signtlicantly add to the information conveyedbythe estiniated annual operating cost. the inclusion ofwhich is 

### mandated bytheAct.

3.ENERGY FAC'IOR FORFREEZERS 

### Some comments suggested that calculation of an unadjusted energy factor for freezers would lead consumers to believe that freezers are less efficient than 

### electric refrigerators and electric refrigerator-freezers. These comments noted that the energy factor for electric refrigeratorshaving a 15° F. freezer compartment is adjusted by a factor of 1.44, 

### and thatthe energy factor for electric refrigerator-freezers having a. 5° F.


### • freezer compartment is 

### adjusted by a. ·factor of 1.63 FEA 

### has determined that consistency requires that the calculation of the energy factor for freezers include an adjustment factor of 1.73, in order to compensate for thelower working 

### temperature of freezers. The energy factor for .freezers has been amended in § 

### 430.22<b> <4> toreflect this 

### change.

Because neither the energy factor nor the adjusted volume is 

### used in the de-

.terminationof the estimated annual operating 

### cost, this 

### adjustment factor will not affect those calculations. The 1972 baseline emciency onwhich theproposed energy**~iency** 

### improvement target for freezers <42 FR

### 36648, July 15, 1977> was based, 

### Will be affected, however. AB 

### a result, appropriate changes will 

### be made in the energy factors associated with the target for freezers.

4. ADJUSTING THE ENERGY FACTOR· One 

### commenter suggested that the concepts ofanadjustedrefrigerated volume and an energy factor·be abandoned
on the grounds that they compromise manufacturers' incentive to add extia insulation to freezer compartments and
so discourage the use of optimal insulation thicknesses. While the concept of the energy factor as proposed is imper- fect, FEA

### believes thatthe"alternative of allowing 

### no compensation for the lower oPerating temperatures offreezing compartments places at an unreasonable dl,,advantage thoseunits with

### higherratios af

### freezervolume to refrigeratorvolume. · 

### RULES AND REGULATIONS

In 

### theory, 

### a. 63-percent increase in freezer compartment insulation would obviate theneed !or an adjustment !actor. In 

### practice, however, the conductance ofthe freezer compartment insulation of most currently a.\-allable refrig- erator-freezers is 

### within 25 percent of 

### theconductance ofthere!rlgerotorcompartment insulation. For this 

### reason, FEA

### believes thatthe concept; of an adjusted energy factor 1s 

### appropriate 

### as a measure of energy consumption which will nssist consumers in making purchasing

### decisions, 

### asrequiredby theAct. AB

### notedabove, FEAhas

### decidednotonJy to retain 

### en adjusted energy !actor !or electric refrigerators nnd electric refrig- erator-freezers, but also 

### to extend this 

### concept 

### to freezers.

The same commenter also suggested thattheenergy !actorfavors larger

### units because the mo.,!or heat transfer mechanisms 

### are more dependent upon area 

### thanvolume. However,theut!lltyof

### a.refrigeration product is 

### a. refiectlon of its volume and not

### its sur!ace 

### nrea, and the measure of emciency would reflect this utlllty. Forexample, the energy !actor correctly indicates that one large unit is pre!erable to two smaller units withthesametotal

### volume.

5, CREDIT FOROTHER ENERGY SAVING DEVICES

FEA 

### and NBS 

### are currently studying the advisablllty of a. 

### credit !or 

### a. switch to interrupt operation of 

### a unit/s evaporatorfan when the unit's door is 

### open. Special credit may be 

### appropriate because the 

### test procedures prescribed 

### today involve 

### a cycle type 

### with doors remaining closed, so that nny 

### advantages of such a. 

### device would not be reflected.

FEA is 

### prepared to amend these test procedures 1! 

### further developments indicate that 

### energy saving devices 

### a.re given inappropriate qredit due 

### to dlfierences between the test procedures and actual consumer 

### use.

CS. TEST VOLTAGE 

### several comments were directed 

### to proposed §430.23 <a.><3> and Cb>C3>, which required basic 

### moqels having 

### a dual voltage rating 

### to be 

### tested at each -design

7. NUJ.tBER OFUNITS TO BE 7'ES'lll> 

### Some comments expressed objections to the samplingprovision !orelectric retrlgerators, electricrefrigerator-freezers, and freezers. Proposed §

### provision was intendedboth

### to provide 

### an acceptable level of

### beling under section 324, !or monitoring the progress of 

### manufacturers toward accomplJshing the energy efficiency 

### improvement targets under section 325, and !or enforcement testing under section 326. These aspects of the appliance program have not, however. been

### quite JXJssilJle that the objectives o!appliance testingunder each or these parts of the program, as 

### well

In 

### order to ellmlnate the problems discussed

### identical. The final te$t procedures for room air conditioners and dishwashers used l::oth these terms in a manner that could be confusing, and the language prescribed today is intended to eliminate this pos- · sibillty ofconfusion.



### a. PRODUCTS COVERED BY THE FINAL TEST PROCEDURES 

### Some comments suggested that a few products cannot be tested satisfactorily using the proposed test procedures. FEA ls 

### prepared to amend the testprocedures

as new products or new design features may require. No specific details have been provided, however, 

### to justify any such amendments of the proposed test procedures at this time.

One commenter specifically statedthat compactrefrigerators couldnotbetested accurately using the proposed test pro- cedures. No**parti~ular** 

### feature of compact refrigerators was cited, however, which would render the test procedures inappropriate for testing these units.

9. AMBIENT TEMPERATURES 

### It was suggested that the test proce- dures be amended to specify that tests be conducted at an ambient temperature of 104° F. Although such a test would provide a. useful performance criterion, the change from the currently specified ambient temperature of 90° F. would not more accurately reflect energy emciency. Therefore, this suggestion 'was not adopted.

10. NORMAL CYCLE 

### Several comments suggested that the
use of the word "normal" in the 

### term "normal cycle" implied that that cycle
was the usual cycle or the cycle expected to be used most often. CQIDmenters therefore took exception to the definition of "normalcycle" which stated that any anti-sweat heater switchwould be 

### 1n thehighest energy consuming posi- tion during this cycle. The term "standard cycle" was offered as a substitute. FEAhasadopted this change.

Suggestions were also made to specify

a. "standard cycle-maximwn" and a. "standard cycle-mlnimwn." FEA wishes to encourage maximwn use of energy- saving devices such as anti-sweat heaters. Evidence was elicited during the public comment period which indicated that anti-sweat heater switches tend 

### to remain in the position set at the factory. In 

### order 

### to encourage manufacturers to shiprefrigerationproductswith the anti-sweat heater switch in the lowest energy**co~uming** 

### position, FEA has determined that a. cycle 

### ill which the .11. CORRELA'rIVE TEST PROCEDURES



### . Several comments indicated that correlative methods havebeen developed by manufacturers of refrigeration products which yield virtually the same results as those obtained through the test proce- dures prescribed today. At this time FEA has notmade a decision onthe feasibility of allowing correlative testing. If

### additionaldata are submittedby individual manufacturers, FEA will examine the possibility of using correlative testing and will determine whether the Act would permit such methods to be used in lieu of the prescribed test procedures.

12. MISCELLANEOUS 

### After careful consideration of all 

### the comments and further consultation with NBS and FTC, FEA has incorporated in the final rule some minor changes that
were notdiscussed above.
C. REGULATIONS PRESCRIBEil

1. TEST PROCEDURES 

### The test procedtires for electric refrigerators, electric refrigerator-freezers, and freezers prescribed today are included in Subpart B and are substantially the same as those proposed, with the exception of the changes discussed above. As 

### with t,he proposal procedures, the test methodology incorporates the a!)proach contained in the Association of Home Appliance ManUfacturers (AHAM) Standard HRF-2-ECFT-1975 for measuring average energy conswnp- tion per cycle type, and the American National Standard <ANS> B38.l-1970 for measuring net refrigerated volwne. For purposes' of FEA's program, the incorporated standards remain applicable
as presently written regerdless of any subsequent amendment of the ANS or AHAM Standard, until further amendmentbyFEA.

Under the requirements of section 32(c) ofthe Federal EnergyAdministration Act of 1974 <15'

### u.s.c. 761 et. seq.)

2. GENERAL :PROVISIONS 

### Also prescribed today are defin1t.1ons of "electric refrigerator," "electric refrigerator-freezer," "freezer," "refriger- ator," and "refrigerator-freezer." Tho definition of the term "basic model" for refrigerators and refrigerator-freezers, and for freezers, has been added. Somo of these definitions were previously pro• posed in 

### Subpart A (41 FR 19980, May 14, 1976; 42 FR 21588, April 27, 1977), Comments which were received regard

.. ing these definitions, and the issues which they raised, have been discussed earlieriI1this

### notice.

3. APPLICATION OF TEST PROCEDURES 

### As discussed previously, the final**t~st** 

### procedures prescribed today must be ap- plied before representations regarding a measure of energy conswnption can b€l made. Because the purposes and needs ofthedifferent elements ofthe appliance program <e.g., labeling, targets> vary, application of the standard test methodology prescribed today may difier 

### 1n
some respects for eachprogramelement. It is expected that instructions on how to apply the standard test methodology to these other elements of the appliance program will be proposed for comment inthenearfuture.

The requirements of §

### 430.24 (a) and <b> of the final regulations apply until such time as final labeling requirements for a particular measure of energy conswnption and the associated test pro- cedure application provision are pre- scribed. After that time, all representa- tions regarding a measure of energy conswnption covered by a labeling rule must be the same as represented on the label.

D. UNIT COSTS OF ENERGY



### Under section 323(b> (2) of the Act, FEA is to provide manufacturers in

### formation as to therepresentative average unit costs of energy. ThJs 

### informa· tion was provided by notice issued July 11, 1977 C42 FR 36549, July 15, 1977),
