SUPPUMINTARY INFORMATION:
A. Background

On October 1. 1917. the Department of Energy (DOE) aaawziecJ 

### Ibe authority of the Federal EnergyAdiii1nistration (FEA) for the Energy eonvservaUon Program for Consumer Products under Section 301.ofthe 

### Department ofEn4!.rgy Orgnlzatlon Act (Pub. L. 95-01). The Energy Conservation Program for Consumer Product. was establishedby FEA purnant to ntle 

### Ill. rart B ofthe Energy Poliey and Conservation Act [EPCA). Subsequently, EPCA was amended by the NatiolU'J Energy Conservation Policy Act (NECPA). Rererences in this notice to "the Act" or 10 section of the Act. refer to the Energy Policy and Conservation 

### Act. as amended by NECPA.

The Act requires DOE to prescribe standardized test procedures to measure the energy consumption ofcertain

consumer products. Including refrigerators 

### and refrigerator-freezers. and freezers. Testprocudurea were proposed for refrigerators and refrigsrator-freezera. and freezers by notice issued April 12, 1977 (42 FR 21516, April 21.1911). A public bearing on the proposed test procedures was beld on June 14. 1977. Final test procedures were prescribed on September 6, 1977 (42 FR 46140. September 14. 19'17).

Subsequently. a Petition for Rulema\dng was submitted by the • Association 

### oJ Home Appliance Manufacturers (AHAM). This petition requested that DOE examine shortened test procedures for refrigerators and refrigerator-freezers. 

### md freezers. AHAM stated that Ita alternate test procedures were much less burdensome and would give results that would differ by less than four percent from those obtained under the exi.ting DOE test procedures. Upon the request ofDOE. the National Bureau ofStandards (NBS) experimentally evaluated the alternate test procedures sup,gested by 

### AHAM. After study. NBS recommended to DOE revised test procedures which incorporated many ofthe AHAM suggestions. On July 14.1980. DOE Federal**~** Vol 46. No. 198

Wednesda,. October 14. 1981

proposed thelle revised test procedures

as an amendment to the existing procedures (45 FR 41396).

Information received by DOE during the pubUc bearing on September 9. 1980. and In written comments in response to the July 14. proposal ravealed certain inadequacletl 

### with the definition of IIteady state conditions and with 

### the requirements

# sracUenL lnsufficleat 

### IDformation wu available in the rulemaldns record to addreu these

areas satisfactorily.Today. DOE Is proposing certaln additional chanaes to the refrigerator and**"frigerator-~r.** and freezer proposed teat procedures of July 14. to satisfy concerns raisedby commenters.
B. Disellsllon

(1) Temperature Contrals. For products with a single temperature control knob. 

### the existing test procedures require that energy consumption be measured at three control settinga (warm. mid. and cold). The July 14proposal required only two settin3S. one at 

### the midpoint and the

,. 'ber at either the warm or cold setting

&0 that the temperatures ofthe 

### two settings bncketthe standardized temperature; Standardized temperatures

are 15· F in the freezing compartmant for refrigerators. 5- F in the 

### freaing compartment for refrigerator-freezers. f1" F for 

### freezers.. and 33" F in the fresh food compartment for**~-refrigerators.**

On product. with two temperature controls. the present 

### test procedures require thatproducts 

### be tested·at eo"':'" of the extreme posiHonl ofthe controls (warm/warm. warm/cold. cold/warm. and cold/cold}. The July 14 proposal reduced the number oftest points from four to two. The finst test Is made with '\ both controls set at their midpoints. and the second test is mede at either the warm/warm (lr cold/cold setting as required 10 that the compartment temperaturel bracket the standardized temperature.

(2) Three-yearPeriod. The July 14 proposal wo.uld have eliminated the existing test procedures for refrigerators and refrigerator-freezers. and freezers. Since the proposed snd existing test procedures give almost identical results. several commenters requested that a three-year period be allowed during which the use ofeither test procedure would be allowed. The commenters

staled that manufacturers should have the option to teat their producb under either tesl procedure durinlthis three·

. yearperiod 10 they would not have to releallmmediate}y aU models which are currently labeled.Slnce the differences in resulb obtained betweeD the two teat procedures ahould be small and would not mislead consumers. DOB Is propoalng uae of eitherprocedure during

a three-year period.

(3) T ••

, 

### CiuJmberAmbient Temperatun Gradient. Commentera noted that the DOE revised procedure

. did**~** cootaiD a requirement that the test chamber¥ertical ambient air**tempera~** gradient be maiDtained when testa are iD progrea

.. DOB and NBS agree lhls requirement Is advisable. Therefore. both the requirement and it method for measuring ambient gradient

are included in today'. proposed amendmenl

(4) Definition of"Steady·stote" Conditians. The July 14 proposal required that a tesl period could nat start until the.unil being tested reached "steady-state" (non.varying) temperature conditions. However. a precise definition of "steady-elale" conditions was not iDcluded. Commenters rec;ueated that DOE incorporate the definition used in AHAM Standard HRF-1-1979. NBS and DOE evaluated this suggestion but found that the AHAM definition would not completely define steady staie conditions for all products under all circumstances. Consflquently, 

### today', proposed rule includes a new defmitioll of "steady-state" conditioIl8 that i. designed to be compatible with the July 14 teat methods under 

### aU circumstances.

(5)Accuracy ofTe.mperalurtt Measurements. While analyzing public coruments. NBS discovered that the AHAM standard (AHAM-HRF-1-1979), referenced by the July 14 prop05al, did not clearly define the required accuracy of temperature measUrements. Consequently, today's proposed rule Specifies the ",me accuracy requirement contained in the existing DOE test procedure.

(6) Non-time Initiated (Demand) Defrost. Many commenters objected to the inclusion in the July 14 proposed rule of a procedure for measuring the energy consumption ofrefrigeration products with non-time initiated (demand) defrost. They stated that this type of system. although technologically feasible. is n'''' currently marketed In the United States. After publication of the proposed rule, the "Provisions for the Waiver of Consumer Product Test Procedures:' which allow the Assistant

- Secretary for Conservation and Renewable Energy temporarily to waive test procedures for a particularcovered product. became effective (45 

### FR 64108, September 26. 1980}. Consequently, DOE has concluded that test fd'Ocedures for non·time lnltl.ted defroet products are not currently needed. 

### Ifsuch products

are prot'uced in the 

### future and the then existing test 

### proc:edurea do not accurately measure the true energy consumption of the machine

.. the manufacturer may petition for a waiver froM the te.t proceduree (10 CFR 430.21). Accordingly, today's proposed 

### ru.la doe. not include telt procedure. for non-time Initiated defrost producta.

{7} Lor.a-time InitiatedDefrost. One commenter. when reviewing the nontime irJtiated defrost procedures. noted that these procedures could be adapted very easUy to newly-designed automatic d!!frost products which operate for unusuaUy long time periods.**I.e~** greater than 24 hours. between defrosting. NBS investi&ated this method and found that such a procedure could greatly reduce test iline, since a test point that currently required four days oftesting might be obtained in lesa than Z4 hours with almost with no loss ofaccuracy. Today'. proposal Incorporates an alternate procedure for testing of automatic defrost refrigerator-freezers and freeurs which require more than 14 hours ofcompresaor-operating time between defrost periods. NBS andDOE chose the fourteen hour period because

a product whose compressor 1'UIl8 6O'Jri of the time would require a test period of greater than 24 hours. A longer test period could be burdensome arid does not resullin significantly increased

. accuracy since units which operate for

more than 14 hours between defrost cycles use only about 1.5" of their electri.cal energy consumption to perfonn the defrost function.

(8) SpeciaJCase1Ifor Refrigerators andRefrigerotor-freezers. NBS review of the July 14 proposal bas indicated that there era two cases. though occurring infrequently, where the calculation procedures need to be defined more precisely.TIle first case
occurs when the &eezer compartment (or in the case ofan all-refrlgerator, the fresh food compartment] temperatures

are always below the standardized temperatures for reporting energy consumption. In this case. the energy consumption to be reported Is that which oa.-urs at the warmest control settings; hence there is no need to perform a test at the colder settings. The second case occurs when the compartment temperatures are always above the standardize temperatures. These conditions usually characterize a product whose refrigeration system is uoderdcaigned.. For these products. tha medium end cold temperature control settings 

### will likely result in compartment temperat'.lJ'8' very close together since the compressor 

### will probably be running almost constantly at both control settings. Since energy use is determined by extrapolating the resulta of these two test points. imaU errors In each point could result in large errors in the extrapolated result. Conaequently. a test witb tbe temperature controls set iD the

warm positions ,bould 

### be performed so the energy D88 may be determined ;nuch

mora precUely by an extrapolation from the warm teat point to the cold test pOint. Todaysproposed teat procedures Include the aboveprovisions for treating these two lpedal cases.

(9)AlJ-re/rigemlors. The July 14 propo.al defined an all-refrigerator U B l'i!frlgerator whose freeezing**!;~,mpartt~.mt** volume was leas than 0.25 cubic feet. 

### Dull to the smallrlze of this compartment. no load of frozen 

### food packages was required in the freezer. A manufacturerrequested that this definition 

### be '.:hanged to include models whose freezer volume was less than 0.30 cubic feel The company makes a product with a freezer volume greater than 0.25 cubic feet butles8 than0.30 cubic feel The commenter Itated that the freezer unit 

### fa still too 

### tma1l to have the frozen fond packnges properly arranged. NBS analyzed these comments and concluded that refrigl"rBtors whose freezer volumes are smaller than 0.50 cubic feet .would probably not offer enough space to arrange properly a test load in the**freuer~In** todaya proposed rule. DOE hal changed the definition of

an all-refrigerator to include units with freezer volumes less than 0.50 cubic feet. These units 

### will be tested without a load in the freezer. DOE invites comment and data from interestedparties concerning the definition ofan all-refrigerator.

Commenters 

### also requested that DOE provide a method 

### to calculate 

### t.b. adjusted volumll ofan all-refrigerator. Adjusted volvme is 

### used to compensate for the fact that oftwo similar products with equal**~tal** volumes. the unit with the larger ratio offreezing compartment volume to total volume 

### will consume
more energy. For refrigerators. refrigerator-freezers. 

### and freezers. the adjusted volume is calculatedby the freezer volume multiplying by aD ad1ustment factor, and the resulting product Is added to the fresh food volume. This adjusted volume. which is

a measure ofuaeful output ofservices. is divided by the electrical consumption to determine the energy factor of the producL For the all.refrigerators. adjustment factor values of 1.12 and 1.0

were suggested by eommenters. The i.12 factor II based on an auumed freezing compartment temperature of32° F. which cannot be confirmed Ilnca no freezer compartment temperature' mealurements are required. Even 

### Itthe temperature were known to 

### be kept at 32° F, the 1.12 adjultmeflt factor would only be appropriate 

### Itthe freezing

. compartment In all-refriseratora was confIgUred In the same geometrical fashion al In refrigeratora and • refrigerator-freezers. Typically. this Is not the cale Iince aD-refrigerator freezing compartments do not usuaDy occupy the entire upper portion ofthe Itorage volume. Consequently, today's propoled rule includes an adjustment factor of 1.0. 

### and the adjusted volume 

### 01

an aD-refriserator would be equal to the lum ofthe volumes ofthe frelh food and freezer compartments.

### Freezer Two-point

### and DOE. These data

were found to 

### be insufficient to IUpport the commenter's polition.

Consequently, today'l proposed freezer test procedure contains the twopoint test procedure 

### as proposed on July**1~**

### FreezerPerformance. Storage volume, in addition to eltlmated annual operating cost. II the only measure 

### 01 performance for freezera in the ex1stina test procedurel; One manufacturer requested that DOE Include another

measure offreezing performance In the freezer test procedure. Freezing performance would quantify the rate at which the freezer could lower the interior termperature.
