### Delermination of Enersy 

### Consumptjon Basedon Fresh Food Compartment Temperature. Since the temperature in the freezer compartment 

### ofan 21!-refri"erator

### is no! a critical operating par;meter. the 

### July 14. 1980 proposal called for the determination of energy consumption to be based on the lemperuture in the fresh food compartment.The "standardized" 

### fresh food**r~mparlmen!** temperature. proposed <'0 July 14. 1980. was 38'F (J.3·C). The July 14 notice also proposed that no temperature measurements be made in the freezer compartlTlenl. No
comments were received regarding

### the proposed changes.Today's final rule incorporates these changes.

### The provisions for testing ell.refrigerators

are the SGme as those for testing single control device refrigerators (described in Section 2. 

### infra) with the exception that only 

### fresh food compartment tcmperaturr. is used in determining per cycle energy consumption.

(c) 

### Calculation 

### of Adjusted Tolal 

### Volume. \\'hile the July 14. 1980. proposal broke oul all-refrigerators as a type ofrefrigerator. 

### it did not provide for calculutlng 

### the adjusled tolal volume 

### of

an ull.refrige:alor differently from that ofa refrigerator. Adjusted total volume is 

### a mensu:e ofuseful output of services for refrigerators and refrigerator. freezers. and,freezers and 

### is necessary fcr compu!!ng Energy Factor

meosure of Ihe ovcTnll efficiency of the product. The adjusted total volume III divided by the per cycle energy consumption of the unit 10 determine the 

### F.F. (Per cycle energy consumption 

### is a calculnted Villus e'lulvuirnt to the
amount olenergy thol would be consumed by 8 unit over 8 24 hour period.) Af:cr actual freezer compartment Bnd fresh food comportment volume have been determined. the adjusted total volume 

### of the unit is culcuiated by mul!iplying the freezer compartment volurr.e by an adjustment factur und adding the result
to the fresh rood compartment volume.

Included in the July 14 comments rela!lng 10 all·refrigerators were recommendations to change the ndjuslmenl factor from 1.44 (as yrovided for rcfrige"alors] to either 1.12 or 1.0. The 1.12 factor Wll9 based on the assumption trw! all·rd,igerelor freezer compartments would be at a temperature of3Z'F [O'C) when the fresh food comparlment temperature was 38'F (3.3'C). The adjustment f;;eler of 1.0 wus recornmend("d on the basis lhal the volume of the freezer compartme::1 or un all.refrigerator. being small and of limited 

### \,tiIily. should not he "adjusted," In other words.

use of a 

### 1.12 adjustment factor instead of

The 1.12 factor Wll9 based on the assumption trw! all·rd,igerelor freezer compartments would be at a temperature of3Z'F [O'C) when the fresh food comparlment temperature was 38'F (3.3'C).

when tests are in progress. DOEand NIlS agree this reguirement is advisable.

The vertical ambient air temperature conditions during the testing process can acrect the measured energy use during the test. The existing DOE test procedt're requires that the operational conditions ofthe AHAM standard apply. This standard in turn refers to ANSI 838.1-1970 which. in section 6.2.1., specifil:'s the maximum allowed vertical ambient temperature gradient to be OSF per fool (0.ge

### CpermeIer). The standard docs not specifically stale Ihal this limit prevails during the test.The commenters poinled this out amI requested that this he stated in the final rule. Thus. in today"s rule a requirement that the ,'erlir:al gradient be maintained during Ihe lest is included and the temperature measurement sensorlocations are explicitly defined.



### 9, fi'eezer

### Two-point Test. One commenlercontended that the two-point freezer lesl procedure proposed onJuly 14.1980. would cause a decrease in intraiaboralory repealabilityoflest resulls. which due 10 

### Ihe statistical sampling plnn. would increase the

numver oflesls required to maintain the

same Iltatistical confidence le\·el. Dala from a single lesl ofa single product

was provided by the commenter and

was reviewed by NilS and DOE. The dula wus found 10 

### be in(lufficientto supporl thn commenter's contention. For exumple. the commenter supplied an energy consumplion versus freezer compartment lempetuluregraph displaying the test resulls for the lest he conducted hut did not identify the lempl!rllture control knob settings corre!lponding to the duta points displrlyed. Also. it 

### appeared that the "cold" test point was made with the lemperature control device shorlcircuited to clluse the compressor to run continuously.Testing in such a manner docs not conform to the DOE lesl procedures. Finully. any attempl 10 draw conc:lusions from a single test ofa single product is unwise since no !llalislical confidence can be assigned to Ihe**te~1** 

### resulls. Thus. no change was made 10 the DOE test procedure.



### 10. FreezerPerformance. Storage \'olume and eslimated annual operating cost are the only measures of perfurmance for freezers if' 

### the existing lesl procedures. One manufacturer requested Ihat DOE include anolher

measure ofperformance in Ihe freezer
test procedure.That mO::dsure would be the rale offreezing. It 

### would quantify thn time it takes a freezer to lower the temperalure ofa load.The commenter noted thul Ihe p'oposed tesl procedure**II~millto** 

### direct manufacturers towards smaller. lower cost refrigeration compressors to achieve favornble test results (high efficiencyratings and low estimated annual operatingcost figures). Suchunits wouldbe characterizedby low freezing rates. Thecommenterwas concerned that such units would not perform satisfactorily and maypose a health hazard since a largeroom temperatureload placed in the unit might result in the thawing ofthe existingfrozen load during the extended time period that a freezer with a low freezing rate would take to stabilize the entire load at a subfreezing temperature. By including a measure offreezing rate p(;rformance in the testprocedure. the
commenterhopes to discourage manufacturers from pursuing such a design option. DOEacknowledges that such freezer designs are technically possible buthas noknowledge that such freezer designs currently exist. ' Therefore, DOE has not opted to include

a measure offreezing performance in the freezer test procedure prescribed today.



### 11.AccuracyofTes!Measurements. While analyzing public comments to the July 14, 1980, proposal.NBS discovered that the new AHAM standard (AHAMHRF-1-1979) referenced did not clearly define the required accuracy of temperature measurements. Section 7.3.1 ofthis stllndard states. "Temperature readings are to he accurate within 1"F (O.S'C)." 

### II is uncleur whether this requirement means that the accuracy of temperature measurements should be ±O.S'F (0.Z8'C) 01' 

### ±1.0·F (O.S'C). Consequently. for the October 14. 1981. proposed rule. DOE added a temperllture measurement ar:curacy requirement (sections S.l. Appendices Al and (31) to specify the same accuracy
liS 

### thut specified in the e)<.\sling test procedure. i.e

.. ±O.S'F (0.28'C).

In response to this proposed rule. one commenter requested that this accuracy specification ue changed to ± 1.0·F (OSC).The commenter interpreted the tl'mperllture accuracy requirement of AIIAMIIRF-1-1979 to be ± 1.0'F (O.S'C). lie aS8P.rted thut even "Special Type 

### "T' thermo-couple wire has a limit oferrorof ± O.7S'F (0.42'C) and that recorders with a scale fange of1SO'P (83'C) have a limit oferrorof ± 0.37S'F (0.2l'C). 

### It WilS 

### c1uimed thllt these factors combine to limit the accuracy of temperature measurement to ± 1.13'F (0,63'C) which makes the proposed accuracy requirement of ± O.S'F (0.28'C) unduly burdensome. 

### It is true that the conditions staled will not pro\'ide the acr:uracy specified by the proposed test procedure, However. there are steps which can ve tilken to overcome this problem.The first step is to qualify, i.e.
to determine the limit oferror associated with. the thermocouple wire used for the test. This canbe done to

. greateraccuracy than a thermocouple' wire manufacturer canguarantee for large quantities ofthermocouple wire. The next step is to usc recorders with scale ranges ofless than lS0'P (83·C).

### 12. Three- rearPeriod. TheJuly 14. 1980. proposal wouldhave eliminated the existing test procedures for refrigerators and refrigerator-freezers. and freezers. Since the proposed and existing test procedures give almost identical results. several commenters requested that a three-yearperiod be allowed during which the use ofeither test procedure would be allowed.The commenters stated that manufacturers should have the option to test their products under eithertest procedure during this three-yearperiod so they will not have to retest immediately all models which are currentlylabeled. Since there will be little difference in testresultsbetween the two test procedures. DOE has provided for the

use ofeitherprocedure during a threeyearperiod In today's final rule. After the three-yearperiod. only the alternative uniform test methods for measureing the energy consumption of refrigerators and refrigerator-freezers. and freezers (Appendices A1 and B1) may be used.

as proposed is the method for clliculatingthe adjusted total volume of

an all-refrigerator. However. an allrefrigeratoris a special case ofa refrigerator and the methods for determining the adjusted total volumes ofthese products differonlyby the adjustment factors used in the calculations.Therefore. section 6.1.3 has been deleted and section 6.1.1. the method for calculating the adjusted total volume ofa refrigeratorhas been modified to include the adjustment factor for an all-refrigerator and to specify that this particular adjustment factor be used when calculating the adjusted total volume ofa refrigerator

when tests are in progress. DOEand NIlS agree this reguirement is advisable.

The vertical ambient air temperature conditions during the testing process can acrect the measured energy use during the test. The existing DOE test procedt're requires that the operational conditions ofthe AHAM standard apply. This standard in turn refers to ANSI 838.1-1970 which. in section 6.2.1., specifil:'s the maximum allowed vertical ambient temperature gradient to be OSF per fool (0.ge

### CpermeIer). The standard docs not specifically stale Ihal this limit prevails during the test.The commenters poinled this out amI requested that this he stated in the final rule. Thus. in today"s rule a requirement that the ,'erlir:al gradient be maintained during Ihe lest is included and the temperature measurement sensorlocations are explicitly defined.



### 9, fi'eezer

### Two-point Test. One commenlercontended that the two-point freezer lesl procedure proposed onJuly 14.1980. would cause a decrease in intraiaboralory repealabilityoflest resulls. which due 10 

### Ihe statistical sampling plnn. would increase the

numver oflesls required to maintain the

same Iltatistical confidence le\·el. Dala from a single lesl ofa single product

was provided by the commenter and

was reviewed by NilS and DOE. The dula wus found 10 

### be in(lufficientto supporl thn commenter's contention. For exumple. the commenter supplied an energy consumplion versus freezer compartment lempetuluregraph displaying the test resulls for the lest he conducted hut did not identify the lempl!rllture control knob settings corre!lponding to the duta points displrlyed. Also. it 

### appeared that the "cold" test point was made with the lemperature control device shorlcircuited to clluse the compressor to run continuously.Testing in such a manner docs not conform to the DOE lesl procedures. Finully. any attempl 10 draw conc:lusions from a single test ofa single product is unwise since no !llalislical confidence can be assigned to Ihe**te~1** 

### resulls. Thus. no change was made 10 the DOE test procedure.



### 10. FreezerPerformance. Storage \'olume and eslimated annual operating cost are the only measures of perfurmance for freezers if' 

### the existing lesl procedures. One manufacturer requested Ihat DOE include anolher

measure ofperformance in Ihe freezer
test procedure.That mO::dsure would be the rale offreezing. It 

### would quantify thn time it takes a freezer to lower the temperalure ofa load.The commenter noted thul Ihe p'oposed tesl procedure**II~millto** 

### direct manufacturers towards smaller. lower cost refrigeration compressors to achieve favornble test results (high efficiencyratings and low estimated annual operatingcost figures). Suchunits wouldbe characterizedby low freezing rates. Thecommenterwas concerned that such units would not perform satisfactorily and maypose a health hazard since a largeroom temperatureload placed in the unit might result in the thawing ofthe existingfrozen load during the extended time period that a freezer with a low freezing rate would take to stabilize the entire load at a subfreezing temperature. By including a measure offreezing rate p(;rformance in the testprocedure. the
commenterhopes to discourage manufacturers from pursuing such a design option. DOEacknowledges that such freezer designs are technically possible buthas noknowledge that such freezer designs currently exist. ' Therefore, DOE has not opted to include

a measure offreezing performance in the freezer test procedure prescribed today.



### 11.AccuracyofTes!Measurements. While analyzing public comments to the July 14, 1980, proposal.NBS discovered that the new AHAM standard (AHAMHRF-1-1979) referenced did not clearly define the required accuracy of temperature measurements. Section 7.3.1 ofthis stllndard states. "Temperature readings are to he accurate within 1"F (O.S'C)." 

### II is uncleur whether this requirement means that the accuracy of temperature measurements should be ±O.S'F (0.Z8'C) 01' 

### ±1.0·F (O.S'C). Consequently. for the October 14. 1981. proposed rule. DOE added a temperllture measurement ar:curacy requirement (sections S.l. Appendices Al and (31) to specify the same accuracy
liS 

### thut specified in the e)<.\sling test procedure. i.e

.. ±O.S'F (0.28'C).

In response to this proposed rule. one commenter requested that this accuracy specification ue changed to ± 1.0·F (OSC).The commenter interpreted the tl'mperllture accuracy requirement of AIIAMIIRF-1-1979 to be ± 1.0'F (O.S'C). lie aS8P.rted thut even "Special Type 

### "T' thermo-couple wire has a limit oferrorof ± O.7S'F (0.42'C) and that recorders with a scale fange of1SO'P (83'C) have a limit oferrorof ± 0.37S'F (0.2l'C). 

### It WilS 

### c1uimed thllt these factors combine to limit the accuracy of temperature measurement to ± 1.13'F (0,63'C) which makes the proposed accuracy requirement of ± O.S'F (0.28'C) unduly burdensome. 

### It is true that the conditions staled will not pro\'ide the acr:uracy specified by the proposed test procedure, However. there are steps which can ve tilken to overcome this problem.The first step is to qualify, i.e.
to determine the limit oferror associated with. the thermocouple wire used for the test. This canbe done to

. greateraccuracy than a thermocouple' wire manufacturer canguarantee for large quantities ofthermocouple wire. The next step is to usc recorders with scale ranges ofless than lS0'P (83·C). The limit oferror associated with recorders with scale ranges less than lS0'P (83'F) is less than for those with scale ranges of 1SO'

### I-' (83'C) ormore. Following these two steps. DOE and NBS find that temperature measurements can be made with an accuracy of ± OSF (0.28·C).
