11972 Federal Register / Vol. 86, No. 38 / Monday, March 1, 2021 / Notices 

1The petition did not identify any of the 

information contained therein as confidential 

business information. 

a. First and foremost, due to the size of a 

refrigeration system designed for a wine 

cellar, WhisperKOOL uses fractionalhorsepower reciprocating compressors, 

which are fundamentally more limited in 

space and design, and are inherently less 

efficient than larger compressors. For 

example, WhisperKOOL’s most-sold cooling 

unit uses an Embraco-brand compressor 

which, at wine cellar conditions has an EER 

of about 9.85 BTU/Wh. At the same 

conditions, by comparison, a more-modern 

scroll compressor rated at 1.8 HP has an EER 

closer to 11 BTU/Wh. This is the case across 

the board with WhisperKOOL fractionalhorsepower compressors (Embraco brand). 

b. Additionally, some installs are difficult 

and require the use of a duct-able unit. This 

leads to the need for higher-wattage fans 

being used in WhisperKOOL products, 

further to the detriment of the overall energy 

efficiency. 

c. Some of the most efficient modern 

compressors which operate in the fractionalhorsepower range use R290 as the refrigerant 

(Propane). However, an R290 charging station 

retrofit would be excessively invasive to 

WhisperKOOL’s facility as well as too costly 

to redesign all products in such a manner. 

Success of the Application for Interim 

Waiver Will 

Success of the application for Interim 

Waiver will ensure that manufacturers of 

walk-in wine cellar cooling systems can 

continue to participate in the market. 

What Economic Hardship and/or 

Competitive Disadvantage is Likely To 

Result Absent a Favorable Determination on 

the Application for Interim Waiver 

Economic hardship will be loss of sales 

due to not meeting the DOE energy 

conservation standards set forth in 10 CFR 

431.306 if the existing products were altered 

in order to test per current requirements set 

forth in 10 CFR 431.304 and AHRI 1250, it 

would add significant cost and increase 

energy consumption. 

Conclusion 

WhisperKOOL seeks an Interim Waiver 

from DOE’s current test method for the 

measurement of energy consumption of walkin wine cellar Self-contained and Split 

cooling systems.

Case Number 2019–009 

Interim Waiver Order 

I. Background and Authority 

The Energy Policy and Conservation 

Act, as amended (‘‘EPCA’’),2 authorizes 

the U.S. Department of Energy (‘‘DOE’’) 

to regulate the energy efficiency of a 

number of consumer products and 

certain industrial equipment. (42 U.S.C. 

6291–6317) Title III, Part C 3 of EPCA, 

added by the National Energy 

Conservation Policy Act, Public Law 

95–619, sec. 441 (Nov. 9, 1978), 

established the Energy Conservation 

Program for Certain Industrial 

Equipment, which sets forth a variety of 

provisions designed to improve the 

energy efficiency for certain types of 

industrial equipment. Through 

amendments brought about by the 

Energy Independence and Security Act 

of 2007, Public Law 110–140, sec. 312 

(Dec. 19, 2007), this equipment includes 

walk-in coolers and walk-in freezers, the 

subject of this Interim Waiver Order. (42 

U.S.C. 6311(1)(G)) 

The energy conservation program 

under EPCA consists essentially of four 

parts: (1) Testing, (2) labeling, (3) 

Federal energy conservation standards, 

and (4) certification and enforcement 

procedures. Relevant provisions of 

EPCA include definitions (42 U.S.C. 

6311), test procedures (42 U.S.C. 6314), 

labeling provisions (42 U.S.C. 6315), 

energy conservation standards (42 

U.S.C. 6313), and the authority to 

require information and reports from 

manufacturers (42 U.S.C. 6316). 

The Federal testing requirements 

consist of test procedures that 

manufacturers of covered equipment 

must use as the basis for: (1) Certifying 

to DOE that their equipment complies 

with the applicable energy conservation 

standards adopted pursuant to EPCA (42 

U.S.C. 6316(a); 42 U.S.C. 6295(s)), and 

(2) making representations about the 

efficiency of that equipment (42 U.S.C. 

6314(d)). Similarly, DOE must use these 

test procedures to determine whether 

the equipment complies with relevant 

standards promulgated under EPCA. (42 

U.S.C. 6316(a); 42 U.S.C. 6295(s)) 

Under 42 U.S.C. 6314, EPCA sets forth 

the criteria and procedures DOE is 

required to follow when prescribing or 

amending test procedures for covered 

equipment. EPCA requires that any test 

11974 Federal Register / Vol. 86, No. 38 / Monday, March 1, 2021 / Notices 

4A notation in the form ‘‘CellarPro, No. 1’’ 

identifies a written submission: (1) Made by 

CellarPro; and (2) recorded in document number 1 

that is filed in the docket of this petition for waiver 

(Docket No. EERE–2019–BT–WAV–0028) and 

available at http://www.regulations.gov. 

5The DOE test procedure incorporates by 

reference Air-Conditioning, Heating, and 

Refrigeration Institute (‘‘AHRI’’) Test Standard 

1250–2009, ‘‘Standard for Performance Rating of 

Walk-in Coolers and Freezers’’ (including Errata 

sheet dated December 2015) (‘‘AHRI 1250–2009’’). 

Section 6 of that standard defines walk-in box 

thermal loads as a function of refrigeration system 

net capacity for both high-load and low-load 

periods. The waiver petition asserts that wine 

cellars do not have distinct high and low load 

periods, and that the box load levels in the test 

standard are not representative for wine cellar 

refrigeration systems. 

procedures prescribed or amended 

under this section must be reasonably 

designed to produce test results which 

reflect the energy efficiency, energy use 

or estimated annual operating cost of 

covered products and equipment during 

a representative average use cycle and 

requires that test procedures not be 

unduly burdensome to conduct. (42 

U.S.C. 6314(a)(2)) The test procedure 

used to determine the net capacity and 

annual walk-in energy factor (‘‘AWEF’’) 

of walk-in cooler and walk-in freezer 

refrigeration systems is contained in the 

Code of Federal Regulations (‘‘CFR’’) at 

10 CFR part 431, subpart R, appendix C, 

Uniform Test Method for the 

Measurement of Net Capacity and 

AWEF of Walk-in Cooler and Walk-in 

Freezer Refrigeration Systems 

(‘‘Appendix C’’). 

Under 10 CFR 431.401, any interested 

person may submit a petition for waiver 

from DOE’s test procedure 

requirements. DOE will grant a waiver 

from the test procedure requirements if 

DOE determines either that the basic 

model for which the waiver was 

requested contains a design 

characteristic that prevents testing of the 

basic model according to the prescribed 

test procedures, or that the prescribed 

test procedures evaluate the basic model 

in a manner so unrepresentative of its 

true energy consumption characteristics 

as to provide materially inaccurate 

comparative data. See 10 CFR 

431.401(f)(2). A petitioner must include 

in its petition any alternate test 

procedures known to the petitioner to 

evaluate the performance of the 

equipment type in a manner 

representative of its energy 

consumption characteristics of the basic 

model. See 10 CFR 431.401(b)(1)(iii). 

DOE may grant the waiver subject to 

conditions, including adherence to 

alternate test procedures. See 10 CFR 

431.401(f)(2). 

As soon as practicable after the 

granting of any waiver, DOE will 

publish in the Federal Register a notice 

of proposed rulemaking to amend its 

regulations so as to eliminate any need 

for the continuation of such waiver. See 

10 CFR 431.401(1). As soon thereafter as 

practicable, DOE will publish in the 

Federal Register a final rule to that 

effect. Id. 

The waiver process also provides that 

DOE may grant an interim waiver if it 

appears likely that the underlying 

petition for waiver will be granted and/ 

or if DOE determines that it would be 

desirable for public policy reasons to 

grant immediate relief pending a 

determination on the underlying 

petition for waiver. See 10 CFR 

431.401(e)(2). Within one year of 

issuance of an interim waiver, DOE will 

either: (i) Publish in the Federal 

Register a determination on the petition 

for waiver; or (ii) publish in the Federal 

Register a new or amended test 

procedure that addresses the issues 

presented in the waiver. See 10 CFR 

431.401(h)(1). 

When DOE amends the test procedure 

to address the issues presented in a 

waiver, the waiver will automatically 

terminate on the date on which use of 

that test procedure is required to 

demonstrate compliance. See 10 CFR 

431.401(h)(2). 

II. CellarPro’s Petition for Waiver and 

Application for Interim Waiver 

DOE received a petition from 

CellarPro dated September 13, 2019 

seeking an interim waiver from the test 

procedure for walk-in cooler and walkin freezer refrigeration systems set forth 

at Appendix C (CellarPro, No. 1 at p. 1).4

The waiver process under 10 CFR 

431.401 requires that a petitioner must 

request a waiver for there to be 

consideration of a petition for an 

interim waiver. CellarPro later 

confirmed in a May 22, 2020 email that 

its petition should also be considered as 

a petition for waiver (CellarPro, No. 4). 

The primary assertion in the petition, 

absent an interim waiver, is that the 

prescribed test procedure would 

evaluate the specified basic models in a 

manner so unrepresentative of their true 

energy consumption as to provide 

materially inaccurate comparative data. 

As presented in CellarPro’s petition, the 

specified basic models of walk-in cooler 

refrigeration systems operate at a 

temperature range of 45–65 °F; higher 

than that of a typical walk-in cooler 

refrigeration system. Thus, the 35 °F 

temperature specified in the DOE test 

procedure for medium-temperature 

walk-in refrigeration systems would 

result in the prescribed test procedures 

evaluating the specified basic models in 

a manner so unrepresentative of their 

true energy consumption characteristics 

as to provide materially inaccurate 

comparative data. CellarPro also states 

that the specified basic models are 

‘‘wine cellar cooling systems’’ that 

operate at temperature and relative 

humidity ranges optimized for the longterm storage of wine and are usually 

located in air-conditioned spaces. 

CellarPro contends that because of these 

characteristics, wine cellar walk-in 

refrigeration systems differ in their 

walk-in box temperature setpoint, walkin box relative humidity, low/high load 

split,5 and compressor efficiency from 

other walk-in cooler refrigeration 

systems. 

CellarPro states that the specified 

basic models are designed to provide a 

cold environment at a temperature range 

between 45–65 °F with 50–70 percent 

relative humidity (‘‘RH’’), and typically 

are kept at 55 °F rather than the 35 °F 

and <50 percent RH test condition 

prescribed by the DOE test procedure. 

CellarPro states that the refrigeration 

systems are designed solely for the 

purpose of long-term cooling and 

storage of wine. CellarPro also asserts 

that operating a wine cellar at the 35 °F 

condition would adversely 

mechanically alter the intended 

performance of the system, which 

would include icing of the evaporator 

coil that could potentially damage the 

compressor, and would not result in an 

accurate representation of the 

performance of the cooling unit. 

Additionally, a number of the basic 

models of walk-in refrigeration systems 

identified in CellarPro’s waiver petition 

are ‘‘self-contained’’ or single-package 

systems. In its request for waiver, 

CellarPro states that these systems have 

a small footprint and that testing these 

systems using the refrigerant enthalpy 

method in AHRI 1250–2009 is complex 

since mass flow meters would need to 

be installed in parts of the system with 

minimal space. DOE recognizes that 

because of their single-package design, 

these basic models have insufficient 

space within the units and insufficient 

lengths of liquid line and evaporator 

outlet line for the dual mass flow meters 

and the dual temperature and pressure 

measurements required by the test 

procedure’s refrigerant enthalpy 

method. As noted by CellarPro, AHRI 

1250–2009 does not include specific 

provisions for testing single-package 

systems and testing these basic models 

using the refrigerant enthalpy method as 

required by Appendix C would require 

extensive additional piping to route the 

pipes out of the system where the 

components can be installed, and then 

to route them back in to enable the 

Federal Register / Vol. 86, No. 38 / Monday, March 1, 2021 / Notices 11975 

6 In a waiver granted to Store It Cold for certain 

models of single-package units, DOE acknowledged 

a similar issue in which the additional piping 

necessary to install the required testing components 

would affect performance of the units, rendering the 

results unrepresentative. See 84 FR 39286 (Aug. 9, 

2019). In the case of the waiver granted to Store It 

Cold, the refrigerant enthalpy method yielded 

inaccurate data for the specified basic models 

compared to the basic models’ true performance 

characteristics because of the additional piping 

required to attach the testing components required 

by the refrigerant enthalpy test. The same issues are 

present for the specified single package system 

basic models included in CellarPro’s waiver 

petition. 

7 DOE’s meetings with CellarPro and other wine 

cellar refrigeration systems were conducted 

consistent with the Department’s ex parte meeting 

guidance (74 FR 52795; October 14, 2009). The 

AHRI August 2020 letter memorializes this 

communication and is provided in Docket No. 

EERE–2019–BT–WAV–0028–0005. 

8External static pressure is the sum of all the 

pressure resisting the fans. Here, this is chiefly the 

resistance generated by the air moving through 

ductwork. 

9A cooler is a cabinet, used with one or more 

doors, that has a source of refrigeration capable of 

operating on single-phase, alternating current and is 

capable of maintaining compartment temperatures 

either: (1) No lower than 39 °F (3.9 °C); or (2) In a 

range that extends no lower than 37 °F (2.8 °C) but 

at least as high as 60 °F (15.6 °C). 10 CFR 430.2. 

10The specified operating temperatures are 55 °F 

cold-side air entering and 85 °F warm-side air 

entering. Capacities at specified operating 

conditions are included in the ‘‘2020 CellarPro 

Continued 

system to operate during testing.6 This 

additional piping would impact unit 

performance, likely be inconsistent 

between test labs, and result in 

unrepresentative test values for the unit 

under test. AHRI has published a 

revised version of the test standard that 

provides provisions for single-package 

systems without requiring extensive 

additional piping (AHRI 1250–2020, 

2020 Standard for Performance Rating 

of Walk-in Coolers and Freezers). As 

discussed below, the interim waiver 

alternative test procedure presented for 

comment in this notification adopts the 

new test methods included in AHRI 

1250–2020 for single-package units. 

DOE has received multiple waiver 

and interim waiver requests from wine 

cellar manufacturers regarding the 

limitations of Appendix C. In light of 

these requests, DOE met with the AHRI 

and wine cellar walk-in refrigeration 

system manufacturers to develop a 

consistent and representative alternate 

test procedure that would be relevant to 

each waiver request. Ultimately, AHRI 

sent a letter to DOE on August 18, 2020, 

summarizing the industry’s position on 

several issues (‘‘AHRI August 2020 

Letter’’).7 This letter documents 

industry support for specific wine cellar 

walk-in refrigeration system test 

procedure requirements, allowing the 

provisions to apply only to refrigeration 

systems with a minimum operating 

temperature of 45 °F, since wine cellar 

system controls and unit design 

specifications prevent these walk-ins 

from reaching a temperature below 

45 °F. A provision for testing walk-in 

wine cellar refrigeration systems at an 

external static pressure (‘‘ESP’’) 8 of 50 

percent of the maximum ESP to be 

specified by manufacturers for each 

basic model (AHRI August 2020 Letter) 

is also included. 

Accordingly, CellarPro submitted an 

updated petition for waiver and interim 

waiver on October 2, 2020 (CellarPro, 

No. 6). The updated petition states that 

all basic models listed in the petition for 

waiver and interim waiver have a 

minimum operating temperature of 

45 °F and provides maximum ESP 

values for specified ducted selfcontained and ducted split system basic 

models. 

CellarPro requests an interim waiver 

from the existing DOE test procedure. 

DOE will grant an interim waiver if it 

appears likely that the petition for 

waiver will be granted, and/or if DOE 

determines that it would be desirable for 

public policy reasons to grant 

immediate relief pending a 

determination of the petition for waiver. 

See 10 CFR 431.401(e)(2). 

III. Requested Alternate Test Procedure 

EPCA requires that manufacturers use 

the applicable DOE test procedures 

when making representations about the 

energy consumption and energy 

consumption costs of covered 

equipment. (42 U.S.C. 6314(d)). 

Consistency is important when making 

representations about the energy 

efficiency of products and equipment, 

including when demonstrating 

compliance with applicable DOE energy 

conservation standards. Pursuant to its 

regulations at 10 CFR 431.401, and after 

consideration of public comments on 

the petition, DOE may establish in a 

subsequent Decision and Order an 

alternate test procedure for the basic 

models addressed by the Interim Waiver 

Order. 

CellarPro seeks to use an approach 

that would test and rate specific wine 

cellar walk-in refrigeration system basic 

models. The company’s suggested 

approach specifies using an air-return 

temperature of 55 °F, as opposed to the 

35 °F requirement prescribed in the 

current DOE test procedure. CellarPro 

does not specify air return relative 

humidity in their petition, though they 

do state that the subject basic models 

are designed to maintain relative 

humidity between 50 and 70 percent. 

Additionally, CellarPro requests that a 

correction factor of 0.55 be applied to 

the final AWEF calculation to account 

for the different use and load patterns of 

the specified basic models as compared 

to walk-in cooler refrigeration systems 

generally. CellarPro cited the use of 

such a correction factor for coolers 9 and 

combination cooler refrigeration 

products under DOE’s test procedure for 

miscellaneous refrigeration products at 

10 CFR part 430, subpart B, appendix A. 

IV. Interim Waiver Order 

DOE has reviewed CellarPro’s 

application, its suggested testing 

approach, representations of the 

specified basic models on the website 

for the CellarPro brand, related product 

catalogs, and information provided by 

CellarPro and other wine cellar walk-in 

refrigeration system manufacturers in 

meetings with DOE. Based on this 

review, DOE is granting an interim 

waiver that requires testing with a 

modified version of the testing approach 

suggested by CellarPro. 

The modified testing approach would 

apply to the models specified in 

CellarPro’s waiver petition that include 

two categories of WICF refrigeration 

systems, i.e., single package and split 

(matched) systems. The first 17 basic 

models listed in CellarPro’s table 

(1800QTL through 8200VS) are singlepackage systems. All of the single 

package basic models can be installed 

either through the wall of a wine cellar 

or on top of a wine cellar, and the VS 

series basic models can additionally be 

ducted to the wine cellar. The ducted 

configuration is designed to be installed 

remotely from the wine cellar and 

provide cooling by circulating air 

through ducts from the wine cellar to 

the unit and back. The remaining basic 

models (3000S through AH24Sx) are 

split (matched) systems, in which 

refrigerant circulates between the 

‘‘evaporator unit’’ (unit cooler) portion 

of the unit and the ‘‘condensing unit.’’ 

The refrigerant cools the wine cellar air 

in the evaporator unit, while the 

condensing unit rejects heat from the 

refrigeration system in a remote 

location, often outside. The evaporator 

coil of the ducted split (matched) 

system circulates air through ducts from 

the wine cellar to the evaporator coil 

and back to provide cooling, while the 

evaporator coil of the ductless split 

(matched) systems is installed either 

partially or entirely in the wine cellar, 

allowing direct cooling. The capacity 

range of the specified basic models is 

from 1,065 Btu/h to 17,500 Btu/h for the 

specified operating conditions for each 

of the models (CellarPro, No.8).10

EERE–2019–BT–WAV–0028. 

11 Inches of water column (‘‘in. wc’’) is a unit of 

pressure conventionally used for measurement of 

pressure differentials. 

12The duct material, length, diameter, shape, and 

configuration are used to calculate the ESP 

generated in the duct, along with the temperature 

and flow rate of the air passing through the duct. 

The conditions during normal operation that result 

in a maximum ESP are used to calculate the 

reported maximum ESP values, which are 

dependent on individual unit design and represent 

manufacturer-recommended installation and use. 

13Calculations were conducted over an absolute 

roughness range of 1.0–4.6 mm for flexible duct as 

defined in pages 1–2 of an OSTI Journal Article on 

pressure loss in flexible HVAC ducts at https://

www.osti.gov/servlets/purl/836654 (Docket No. 

EERE–2019–BT–WAV–0028–0013) and available at 

http://www.regulations.gov. 

14This approach is used for testing of furnace 

fans, as described in Section 8.6.1.1 of 10 CFR part 

430, appendix AA to subpart B. 

DOE considers the operating 

temperature range of the specified basic 

models to be integral to its analysis of 

whether such models require a test 

procedure waiver. Grant of the interim 

waiver and its alternative test procedure 

to CellarPro for the specified basic 

models listed in the petition is based 

upon CellarPro’s representation that the 

operating range for the basic models 

listed in the interim waiver does not 

extend below 45 °F. 

The alternate test procedure specified 

in the Interim Waiver Order requires 

testing the specified basic models 

according to Appendix C with the 

following changes. The required 

alternate test procedure specifies an air 

entering dry-bulb temperature of 55 °F 

and a relative humidity of 55 percent. 

The alternate test procedure also 

specifies that the capacity measurement 

for the specified basic models that are 

single-package systems (17 basic models 

1800QTL through 8200VS) be 

conducted using a primary and a 

secondary capacity measurement 

method as specified in AHRI 1250– 

2020, using two of the following: The 

indoor air enthalpy method; the outdoor 

air enthalpy method; the compressor 

calibration method; the indoor room 

calorimeter method; the outdoor room 

calorimeter method; or the balanced 

ambient room calorimeter method. 

The required alternate test procedure 

also includes the following additional 

modifications to CellarPro’s suggested 

approach: For systems that can be 

installed with (1) ducted evaporator air, 

(2) with or without ducted evaporator 

air, (3) ducted condenser air, or (4) with 

or without ducted condenser air, testing 

would be conducted at 50 percent of the 

maximum ESP, consistent with the 

AHRI August 2020 Letter 

recommendations, subject to a tolerance 

of ¥0.00/+0.05 in. wc.11 DOE 

understands that maximum ESP is 

generally not published in available 

literature such as installation 

instructions, but manufacturers do 

generally specify the size and maximum 

length of ductwork that is acceptable for 

any given unit in such literature. The 

duct specifications determine what ESP 

would be imposed on the unit in field 

operation.12 The provision of allowable 

duct dimensions is more convenient for 

installers than maximum ESP, since it 

relieves the installer from having to 

perform duct pressure drop calculations 

to determine ESP. DOE independently 

calculated the maximum pressure drop 

over a range of common duct roughness 

values 13 using duct lengths and 

diameters published in CellarPro’s 

installation manuals (CellarPro, No. 11). 

DOE’s calculations show reasonable 

agreement with the maximum ESP 

values provided by CellarPro for the 

specified basic models. Given that the 

number and degree of duct bends and 

duct type will vary by installation, DOE 

found the maximum ESP values 

provided by CellarPro to be sufficiently 

representative. 

Selection of a representative ESP 

equal to half the maximum ESP is based 

on the expectation that most 

installations will require less than the 

maximum allowable duct length. In the 

absence of field data, DOE expects that 

a range of duct lengths from the 

minimal length to the maximum 

allowable length would be used; thus, 

DOE believes that half of the maximum 

ESP would be representative of most 

installations. For basic models with 

condensing or evaporator units that are 

not designed for the ducting of air, this 

design characteristic must be clearly 

stated. 

Additionally, if there are multiple 

condenser or evaporator unit fan speed 

settings, the speed setting used would 

be as instructed in the unit’s installation 

instructions. However, if the installation 

instructions do not specify a fan speed 

setting for ducted installation, systems 

that can be installed with ducts would 

be tested with the highest available fan 

speed. The ESP would be set for testing 

either by symmetrically restricting the 

outlet duct 14 or, if using the indoor air 

enthalpy method, by adjusting the 

airflow measurement apparatus blower. 

The alternate test procedure also 

describes the requirements for 

measurement of ESP consistent with 

provisions provided in AHRI 1250–2020 

when using the indoor air enthalpy 

method with unit coolers. 

Additionally, the alternate test 

procedure indicates that specified basic 

models that are split systems must be 

tested as matched pairs. According to 

CellarPro’s petition, the walk-in 

refrigeration system basic models that 

are split-systems are sold as full systems 

(i.e., matched pairs) rather than as 

individual unit cooler and condensing 

unit components. This Interim Waiver 

Order provides no direction regarding 

refrigerant line connection operating 

conditions, and as such is inapplicable 

to testing the basic models as individual 

components. Consequently, the Interim 

Waiver Order addresses only matchedpair testing of the specified basic 

models that are split-systems. 

DOE notes that, despite the request 

from CellarPro, it is not including a 0.55 

correction factor in the alternate test 

procedure required by the Interim 

Waiver Order. The company claimed 

that such a factor would correct for 

differences in wine cellar refrigeration 

system fan power, compressor 

efficiency, and run time and load 

conditions. CellarPro also observed that 

the test procedure in appendix A to 

subpart B of 10 CFR part 430 

(‘‘Appendix A’’), includes such a factor 

to account for the difference in use and 

loading patterns of coolers (e.g., selfcontained wine chiller cabinets) as 

compared to other residential 

refrigeration products and sought to 

include a factor as part of its petition. 

Coolers, like other residential 

refrigeration products, are tested in a 

90 °F room without door openings 

(section 2.1.1 of Appendix A). The 

intent of the energy test procedure for 

residential refrigeration products is to 

simulate operation in typical room 

conditions (72 °F) with door openings 

by testing at 90 °F ambient temperature 

without door openings. 10 CFR 

430.23(ff)(7). In section 5.2.1.1 of 

Appendix A, a correction factor of 0.55 

is applied to the measured energy 

consumption of coolers so that 

measuring energy consumption at 90 °F 

ambient temperature without door 

openings provides test results that are 

representative of consumer usage at 

72 °F ambient temperature with door 

openings. Specifically, the 0.55 

correction factor reflects that (1) closeddoor operation of self-contained coolers 

in typical 72 °F room conditions results 

in an average energy consumption 0.46 

times the value measured at the 90 °F 

ambient temperature specified by the 

test procedure; and (2) expected door 

openings of a self-contained wine 

chiller would add an additional 20% 

thermal load. Multiplying 0.46 by 1.2 

results in the overall correction factor of 

0.55. See 81 FR 46768, 46782 (July 18, 

2016) (final rule for miscellaneous 

refrigeration products). 

Federal Register / Vol. 86, No. 38 / Monday, March 1, 2021 / Notices 11977 

15Basic model 2000VS was initially included 

twice in CellarPro’s petition, prior to a clarifying 

email on October 26, 2020 from CellarPro stating that this repeated model was intended to be basic 

model 2000VS 220V (CellarPro, No. 7). 

In contrast, these same closed-door 

conditions on which the miscellaneous 

refrigeration correction factor is based 

are not present in the test procedure for 

walk-in cooler refrigeration systems. 

The WICF test procedure does not 

provide for closed-door testing at 

elevated ambient temperatures as the 

test procedure for residential 

refrigeration products does because 

walk-ins are tested and rated by 

component, with a walk-in refrigeration 

system tested and rated separately from 

a walk-in enclosure (panels and doors). 

See 76 FR 21580. Walk-in refrigeration 

load is set by using a representative 

ratio of box load to capacity (see 

discussion below). As a result, applying 

the 0.55 correction factor as suggested 

by CellarPro is not appropriate for the 

specified basic models. 

Further, CellarPro asserted that the 

suggested 0.55 correction factor was to 

address the differences in run time and 

compressor inefficiency of the specified 

basic models as compared to walk-in 

cooler refrigeration systems more 

generally. It suggested that the run time 

for wine cellar walk-in refrigeration 

systems ranges from 50 to 75 percent. 

AHRI 1250–2009 accounts for percent 

run time in the AWEF calculation by 

setting walk-in box load equal to 

specific fractions of refrigeration system 

net capacity—the fractions are defined 

based on whether the refrigeration 

system is for cooler or freezer 

applications, and whether it is designed 

for indoor or outdoor installation (see 

sections 6.2 (applicable to coolers) and 

6.3 (applicable to freezers) of AHRI 

1250–2009). The alternate test 

procedure provided by this interim 

waiver requires calculating AWEF based 

on setting the walk-in box load equal to 

half of the refrigeration system net 

capacity, without variation according to 

high and low load periods and without 

variation with outdoor air temperature 

for outdoor refrigeration systems. 

Setting the walk-in box load equal to 

half the refrigeration system net 

capacity results in a refrigeration system 

run time fraction slightly above 50 

percent, which is in the range suggested 

by CellarPro as being representative for 

the specified basic models. As 

previously discussed, walk-in energy 

consumption is determined by 

component, with separate test 

procedures for walk-in refrigeration 

systems, doors, and panels. Section 6 of 

AHRI 1250–2009 provides equations for 

determining refrigeration box load as a 

function of refrigeration system 

capacity. Using these equations with an 

assumed load factor of 50 percent 

maintains consistency with Appendix C 

while providing an appropriate load 

fraction for wine cellar refrigeration 

systems. Accordingly, DOE has declined 

to adopt a correction factor for the 

equipment at issue. 

Based on DOE’s review of CellarPro’s 

petition, the required alternate test 

procedure laid out in the Interim Waiver 

Order appears to allow for the accurate 

measurement of energy efficiency of the 

specified basic models, while alleviating 

the testing issues associated with 

CellarPro’s implementation of wine 

cellar walk-in refrigeration system 

testing for these basic models. 

Consequently, DOE has determined that 

CellarPro’s petition for waiver will 

likely be granted. Furthermore, DOE has 

determined that it is desirable for public 

policy reasons to grant CellarPro 

immediate relief pending a 

determination of the petition for waiver. 

For the reasons stated, it is ordered 

that: 

(1) CellarPro must test and rate the 

following CellarPro-branded wine cellar 

walk-in refrigeration system basic 

models 15 with the alternate test 

procedure set forth in paragraph (2).

sentences of Section C9.1.1.1 of AHRI 

1250–2020 (‘‘Entering air is to be 

sufficiently dry as to not produce frost 

on the Unit Cooler coil. Therefore, only 

sensible capacity measured by dry bulb 

change shall be used to calculate 

capacity.’’) shall not apply. 

3.3.9. For systems with ducted 

evaporator air, or that can be installed 

with or without ducted evaporator air: 

Connect ductwork on both the inlet and 

outlet connections and determine 

external static pressure as described in 

ASHRAE 37–2009, sections 6.4 and 6.5. 

Use pressure measurement 

instrumentation as described in 

ASHRAE 37–2009, section 5.3.2. Test at 

the fan speed specified in manufacturer 

installation instructions—if there is 

more than one fan speed setting and the 

installation instructions do not specify 

which speed to use, test at the highest 

speed. Conduct tests with the external 

static pressure equal to 50 percent of the 

maximum external static pressure 

allowed by the manufacturer for system 

installation within a tolerance of ¥0.00/ 

+0.05 in. wc. If testing with the indoor 

air enthalpy method, adjust the airflow 

measurement apparatus fan to set the 

external static pressure—otherwise, set 

the external static pressure by 

symmetrically restricting the outlet of 

the test duct. In case of conflict, these 

requirements for setting evaporator 

airflow take precedence over airflow 

values specified in manufacturer 

installation instructions or product 

literature. 

3.3.10. For systems with ducted 

condenser air, or that can be installed 

with or without ducted condenser air: 

Connect ductwork on both the inlet and 

outlet connections and determine 

external static pressure as described in 

ASHRAE 37–2009, sections 6.4 and 6.5. 

Use pressure measurement 

instrumentation as described in 

ASHRAE 37–2009, section 5.3.2. Test at 

the fan speed specified in manufacturer 

installation instructions—if there is 

more than one fan speed setting and the 

installation instructions do not specify 

which speed to use, test at the highest 

speed. Conduct tests with the external 

static pressure equal to 50 percent of the 

maximum external static pressure 

allowed by the manufacturer for system 

installation within a tolerance of ¥0.00/ 

+0.05 in. wc. If testing with the outdoor

enthalpy method, adjust the airflow 

measurement apparatus fan to set the 

external static pressure—otherwise, set 

the external static pressure by 

symmetrically restricting the outlet of 

the test duct. In case of conflict, these 

requirements for setting condenser 

airflow take precedence over airflow 

values specified in manufacturer 

installation instructions or product 

literature. If testing using the outdoor air 

enthalpy method, the requirements of 

section 8.6 of ASHRAE 37–2009 are not 

applicable. 

In Appendix C to Subpart R, revise 

section 3.3.6 (which specifies 

modifications to AHRI 1250–2009) to 

read: 

3.3.6. AWEF is calculated on the basis 

that walk-in box load is equal to half of 

the system net capacity, without 

variation according to high and low load 

periods and without variation with 

outdoor air temperature for outdoor 

refrigeration systems, and the test must 

be done as a matched or single-package 

refrigeration system, as follows: 

For Indoor Condensing Units: 

(3) Representations. CellarPro may not 

make representations about the 

efficiency of a basic model listed in 

paragraph (1) of this Interim Waiver 

Order for compliance, marketing, or 

other purposes unless that basic model 

has been tested in accordance with the 

provisions set forth above and such 

representations fairly disclose the 

results of such testing. 

(4) This interim waiver shall remain 

in effect according to the provisions of 

10 CFR 431.401. 

(5) This Interim Waiver Order is 

issued on the condition that the 

statements and representations provided 

by CellarPro are valid. If CellarPro 

makes any modifications to the controls 

or configurations of a basic model 

subject to this Interim Waiver Order, 

such modifications will render the 

waiver invalid with respect to that basic 

model, and CellarPro will either be 

required to use the current Federal test 

method or submit a new application for 

a test procedure waiver. DOE may 

rescind or modify this waiver at any 

time if it determines the factual basis 

underlying the petition for the Interim 

Waiver Order is incorrect, or the results 

from the alternate test procedure are 

unrepresentative of a basic model’s true 

energy consumption characteristics. 10 

CFR 431.401(k)(1). Likewise, CellarPro 

may request that DOE rescind or modify 

the Interim Waiver Order if CellarPro 

discovers an error in the information 

provided to DOE as part of its petition, 

determines that the interim waiver is no 

longer needed, or for other appropriate 

reasons. 10 CFR 431.401(k)(2).

Federal Register / Vol. 86, No. 38 / Monday, March 1, 2021 / Notices 11981 

(6) Issuance of this Interim Waiver 

Order does not release CellarPro from 

the certification requirements set forth 

at 10 CFR part 429. 

DOE makes decisions on waivers and 

interim waivers for only those basic 

models specifically set out in the 

petition, not future models that may be 

manufactured by the petitioner. 

CellarPro may submit a new or amended 

petition for waiver and request for grant 

of interim waiver, as appropriate, for 

additional basic models of Walk-in 

Cooler Refrigeration Systems. 

Alternatively, if appropriate, CellarPro 

may request that DOE extend the scope 

of a waiver or an interim waiver to 

include additional basic models 

employing the same technology as the 

basic model(s) set forth in the original 

petition consistent with 10 CFR 

431.401(g).

uranium industry on uranium milling 

and processing, uranium feed sources, 

uranium mining, employment, drilling, 

expenditures, and uranium reserves. 

Form EIA–851Q Domestic Uranium 

Production Report (Quarterly) collects 

monthly data on uranium production 

that is reported on a quarterly basis. 

Form EIA–858 Uranium Marketing 

Annual Survey collects annual data 

from the U.S. uranium market on 

uranium contracts and deliveries, 

inventories, enrichment services 

purchased, uranium in fuel assemblies, 

feed deliveries to enrichers, and unfilled 

market requirements for the current year 

and the following ten years. 

DATES: Comments on this information 

collection must be received no later 

than March 31, 2021. Written comments 

and recommendations for the proposed 

information collection should be sent

will continue to be protected under 

CIPSEA. 

EIA proposes to apply exemptions 

under the Freedom of Information Act 

(FOIA) to protect information reported 

on Forms EIA–851A and EIA–851Q 

except for production data. Production 

data will be considered public and may 

be publicly released in an identifiable 

form. For the past six years, the items 

‘‘Respondent and Contact 

Identification’’, ‘‘Company Name’’, and 

all of ‘‘Item 1: Facility Information’’ on 

Forms EIA–851Q and EIA–851A are 

considered public information and are 

publicly released in company or 

individually identifiable form on EIA’s 

website. Data protection methods will 

continue to be applied to the statistical 

information reported on Forms EIA– 

851A and EIA–851Q, except for 

production data.
