SUPPLEMENTARY INFORMATION: The

Energy Conservation Program for

Consumer Products (other than

automobiles) was established pursuant

to the Energy Policy and Conservation

Act (EPCA), Public Law 94–163, 89 Stat.

917, as amended by the National Energy

Conservation Policy Act (NECPA),

Public Law 95–619, 92 Stat. 3266, the

National Appliance Energy

Conservation Act of 1987 (NAECA),

Public Law 100–12, the National

Appliance Energy Conservation

Amendments of 1988 (NAECA 1988),

Public Law 100–357, and the Energy

Policy Act of 1992 (EPACT), Public Law

102–486, 106 Stat. 2776, which requires

the Department to prescribe

standardized test procedures to measure

the energy consumption of certain

consumer products, including heat

pumps. The intent of the test procedures

is to provide a comparable measure of

energy consumption that will assist

consumers in making purchasing

decisions. The test procedures for

central air conditioners and central air

conditioning heat pumps appear at 10

CFR Part 430, Subpart B, Appendix M.

The Department amended the

prescribed test procedures by adding 10

CFR 430.27 on September 26, 1980,

creating the waiver process. 45 FR

64108. The Department further

amended the appliance test procedure

waiver process to allow the Assistant

Secretary for Energy Efficiency and

Renewable Energy (Assistant Secretary)

to grant an Interim Waiver from test

procedure requirements to

manufacturers that have petitioned the

Department for a waiver of such

prescribed test procedures. 51 FR 42823,

November 26, 1986.

The waiver process allows the

Assistant Secretary to temporarily waive

test procedures for a particular basic

model when a petitioner shows that the

basic model contains one or more

design characteristics which prevent

testing according to the prescribed test

procedures, or when the prescribed test

procedures may evaluate the basic

model in a manner so unrepresentative

of its true energy consumption as to

provide materially inaccurate

comparative data. Waivers generally

remain in effect until final test

procedure amendments become

effective, resolving the problem that is

the subject of the waiver.

The Interim Waiver provisions added

by the 1986 amendment allow the

Secretary to grant an Interim Waiver

when it is determined that the applicant

will experience economic hardship if

the Application for Interim Waiver is

denied, if it appears likely that the

Petition for Waiver will be granted, and/

or the Assistant Secretary determines

that it would be desirable for public

policy reasons to grant immediate relief

pending a determination on the Petition

for Waiver. An Interim Waiver remains

in effect for a period of 180 days, or

until the Department issues its

determination on the Petition for

Waiver, whichever is sooner, and may

be extended for an additional 180 days,

if necessary.

On January 24, 1995, NORDYNE filed

a Petition for Waiver and an Application

for Interim Waiver regarding the heat

pump tests. NORDYNE’s Petition seeks

a Waiver from the Department’s test

procedure because, using the test

procedure, the company cannot account

for the energy savings associated with

integrated water heating. NORDYNE has

submitted a modified test procedure to

be used for rating its Powermiser heat

pumps. NORDYNE proposes to

calculate, in addition to the standard

SEER and HSPF, a Combined Cooling

Performance Factor (CCPF) and a

Combined Heating Performance Factor

(CHPF). These performance factors

reflect the energy efficiency of the heat

pump when providing both space

conditioning and domestic water

heating. The heating and cooling mode

test procedures are essentially the same

as the current Department central air

conditioner test procedures found in 10

CFR Part 430, Subpart B, Appendix M.

The NORDYNE test procedures for the

heating and cooling modes differ from

the Department’s in their use of a bin

analysis for SEER, and the use of

seasonal hours rather than fractional

hours for HSPF. NORDYNE states in its

Petition that the modified test procedure

for SEER and HSPF ‘‘yields a nearly

identical result and provides a directly

comparable base for use in determining

CAS-RM-79-102 COMMENT 18
Federal Register / Vol. 60, No. 152 / Tuesday, August 8, 1995 / Notices 40359

energy savings associated with water

heating.’’ In addition, NORDYNE

submitted tests and a rating procedure

to determine the performance of the

heat pump when it heats domestic water

(whether or not space heating or cooling

is also being provided).

NORDYNE also applied for an Interim

Waiver, stating:

• The current test procedure does not

account for the total energy savings of

the Powermiser;

• Carrier Corporation has been

granted a similar waiver for its

Hydrotech product;

• For public policy reasons, the

widespread use of this type of integrated

appliance would be in direct support of

the President’s Climate Change Action

Plan, which lists heating and cooling

and home appliances as key targets for

improvement; and

• Absent a favorable determination

on the Application for Interim Waiver,

NORDYNE would experience an

economic hardship, as discussed in the

confidential statement filed

simultaneously.

The Department agrees that the

current test procedure does not account

for the total energy savings of the

Powermiser. A previous waiver for this

type of equipment was granted by the

Department to Carrier Corporation for

its HydroTech 2000, 55 FR 13607, April

11, 1990. Thus, it appears likely that the

Petition for Waiver will be granted.

In those instances where the likely

success of the Petition for Waiver has

been demonstrated based upon the

Department having granted a waiver for

a similar product design, it is in the

public interest to have similar products

tested and rated for energy consumption

on a comparable basis.

Further, NORDYNE has supplied

evidence of economic hardship if the

Interim Waiver is not granted.

NORDYNE’s confidential statement

claims a substantial investment in the

Powermiser for research and

development, tooling, production, sales

and marketing. The Powermiser

investment represents a large fraction of

NORDYNE’s annual income. Until the

Interim Waiver is granted, NORDYNE is

not able to realize any return on its

investment.

Based on the statements above, the

Department is granting an Interim

Waiver to NORDYNE for its Powermiser

series integrated heat pumps. Pursuant

to paragraph (e) of Section 430.27 of the

Code of Federal Regulations part 430,

the following letter granting the

Application for Interim Waiver to

NORDYNE was issued.

Pursuant to paragraph (b) of 10 CFR

Part 430.27, the Department is hereby

publishing the ‘‘Petition for Waiver.’’

The Petition contains confidential

company information; thus, the

confidential attachment submitted by

NORDYNE is not being published. Due

to its length (39 pages), NORDYNE’s

proposed alternate test procedure is not

being published in the Federal Register.

It is, however, available upon request at

the address provided at the beginning of

today’s notice. NORDYNE has sent a

copy of the Petition for Waiver and a

copy of the Application for Interim

Waiver to all known manufacturers of

domestically marketed units of the same

product type . A summary of the

NORDYNE alternate test procedure is

included in the letter to NORDYNE

granting the Application for Interim

Waiver, which is published with this

Federal Register Notice.

The Department solicits comments,

data, and information respecting the

Petition.

Issued in Washington, DC., July 10, 1995.

Christine A. Ervin,

Assistant Secretary, Energy Efficiency and

Renewable Energy.

July 10, 1995.

Mr. Wayne R. Reedy, Vice President—

Engineering

NORDYNE, 1801 Park 270 Drive, P.O. Box

46911, St. Louis, MO 63146–6911.

Dear Mr. Reedy: This is in response to your

letter of January 24, 1995, submitting an

Application for Interim Waiver and Petition

for Waiver from the Department of Energy’s

central air conditioner and central air

conditioning heat pump test procedure for

NORDYNE’s Powermiser line of heat pumps,

which include special design characteristics

to incorporate domestic water heating.

The current test procedure does not

account for the energy savings associated

with integrated water heating. A previous

waiver for this type of equipment has been

granted to Carrier Corporation, 55 FR 13607,

April 11, 1990. Thus, it appears likely that

the Petition for Waiver will be granted.

In those instances where the likely success

of the Petition for Waiver has been

demonstrated based upon the Department

having granted a waiver for a similar product

design, it is in the public interest to have

similar products tested and rated for energy

consumption on a comparable basis.

Further, NORDYNE’s Application for

Interim Waiver provides sufficient

information to determine that NORDYNE has

and will continue to experience a severe

negative economic impact absent a favorable

determination on its Application.

NORDYNE’s confidential statement claims a

substantial investment in the Powermiser for

research and development, tooling,

production, sales and marketing. The

Powermiser investment represents a large

fraction of NORDYNE’s annual income, and

NORDYNE is not able to realize any return

on this investment until the Interim Waiver

is granted.

Therefore, based on the above,

NORDYNE’s Application for an Interim

Waiver to modify the Department’s test

procedure for its Powermiser line of heat

pumps with integrated domestic water

heating is granted.

NORDYNE shall be required to test its

Powermiser line of heat pumps on the basis

of the test procedures specified in 10 CFR

Part 430, Subpart B, Appendix M, as

modified by additional tests and ratings

described in its proposed alternate test

procedure, to determine the performance of

the heat pump when it operates for the

heating of domestic water, either

concurrently with or separate from the space

heating and cooling modes.

The alternate test procedure is summarized

in Attachment A, attached hereto.

This Interim Waiver is based upon the

presumed validity of statements and all

allegations submitted by the company. This

Interim Waiver may be removed or modified

at any time upon a determination that the

factual basis underlying the application is

incorrect.

The Interim Waiver shall remain in effect

for a period of 180 days, or until the

Department acts on the Petition for Waiver,

whichever is sooner, and may be extended

for an additional 180-day period, if

necessary.

Best regards,

Christine A. Ervin,

Assistant Secretary, Energy Efficiency and

Renewable Energy.

Attachment A

Type of Equipment To Be Covered

The test procedure described herein

applies to electrically-driven, singlespeed compressor air-to-air heat pumps

having a nominal cooling capacity of

65,000 BTU/Hr or less that include an

integral heat exchanger and water pump

for the heating of domestic water, either

concurrent with or separate from the

space heating and cooling modes.

Test Points and Procedures

Standard ratings shall be established

in accordance with 10 CFR Part 430,

Subpart B, Appendix M, ‘‘Uniform Test

Method for Measuring the Energy

Consumption of Central Air

Conditioners.’’ Procedures will also be

compatible with ‘‘Methods of Testing

for Efficiency of Space-Conditioning

Water Heating Appliances that include

a Desuperheater Water Heater’’

ASHRAE Standards Project Committee

137P (under development).

In addition to the standard ratings,

tests and a rating procedure are

described to determine the performance

of the heat pump when it operates for

the heating of domestic water, either

concurrently with or separate from the

space heating and cooling modes.

Table 1 specifies the operating

conditions for all of the tests covered by

CAS-RM-79-102 COMMENT 18
40360 Federal Register / Vol. 60, No. 152 / Tuesday, August 8, 1995 / Notices

the present test plan, along with their

operating and water draw schedules as

Tables 2, 3 and 4. These tests are

summarized as follows:

Space Cooling Mode, Tests 1, 5, 6 and

7

Test 1 (required) is identical to the

Department Test A, Test 5 (required) is

identical to Department Test B, Test 6

(optional) is identical to Department

Test C, and Test 7 (optional) is identical

to Department Test D, except for the

following: The refrigerant-to-water heat

exchanger is filled with water. In order

to not have the water pump cycle on

during tests 1 and 5, it may be necessary

to disable the water pump. If natural

convection within the water system

proves significant, it will be necessary

to close an isolation valve between the

heat pump and the water heater tank.

Space Heating Mode, Tests 11, 12, 13

and 15

Test 11 (required) is identical to the

Department High Temperature Test,

Test 12 (optional) is identical to the

Department Cyclic Test, Test 13

(required) is identical to Department

Frost Accumulation Test, and Test 15

(required) is identical to the Department

Low Temperature Test, except for the

following: the refrigerant-to-water heat

exchanger is filled with water. In order

to not have the water pump cycle on

during tests 11, 13 and 15, it may be

necessary to disable the water pump. If

natural convection within the water

system proves significant, it will be

necessary to close an isolation valve

between the heat pump and the water

heater tank.

Space Cooling/Domestic Water Heating

Mode, Tests 2 and 4

Test 2 is the Department Test A,

combined with water heating. Air side

conditions are held constant and the

system runs continuously, while a series

of water draws are imposed as outlined

in Table 2.

Test 4 is the Department Test D,

which involves cyclic operation of the

heat pump, with a series of water draws

imposed as outlined in Table 3.

The system cyclic schedule is for

energizing of the compressor and indoor

blower control terminal. Actual system

operation will be controlled by the

system internal controls. Depending on

internal controls, the compressor and

one of the system fans may start or

continue to run irrespective of the

compressor terminal being energized.

There shall be no air flow through the

coil with the idle fan. When the indoor

blower is off, the duct shall be blocked.

Space Heating/Domestic Water Heating

Mode, Tests 10 and 14

Test 10 is the Department Cyclic Test

with a series of water draws imposed, as

outlined in Table 3.

Test 14 is the Department Low

Temperature Test combined with water

heating. Air side conditions are held

constant and the system runs

continuously, while a series of water

draws are imposed, as outlined in Table

2.

The system cyclic schedule is for

energizing of the compressor and indoor

blower control terminal. Actual system

operation will be controlled by the

system internal controls. Depending on

internal controls, the compressor and

one of the system fans may start or

continue to run irrespective of the

compressor terminal being energized.

There shall be no air flow through the

coil with the idle fan. When the indoor

blower is off, the duct shall be blocked.

Domestic Water Heating Modes, Tests 3,

8 and 9

Tests 3, 8 and 9 involve cyclic

operation of the heat pump in selfcontrolled response to a series of water

draws, as outlined in Table 4.

Test 3 (required) uses the same

conditions as the Department Test D,

and will result in a cooling effect on the

indoor room.

The conditions of Tests 8 and 9 (both

required) are specified in Table 1. Their

temperatures do not correspond to any

Department tests, but, with the

exception of the temperatures specified

in Table 1, they shall follow the

requirements of Department Test D.

Tests 8 and 9 will result in a cooling

effect on the outdoor room (‘‘O’’

terminal de-energized). When the

indoor blower is off, the ductwork shall

be blocked.

In addition to the normal components

required for indoor space heating and

cooling, the unit shall be connected, as

specified by the heat pump

manufacturer, to a conventional electric

domestic hot water storage tank. The hot

water storage tank shall have a nominal

rated volume of 52 gallons, with an

actual internal volume of 47±1 gallons.

The hot water storage tank shall have an

Energy Factor (EF) rating that is within

±.02 of the EF specified as the Federal

Energy Conservation Standard for 52

gallon electric water heaters, (presently

0.87), as determined by the Department

test and rating standards, contain two

electric heater elements each rated at

nominal 4500 Watts and be connected

to a source of supply water having a

temperature of 58±2 °F. The electrical

voltage supplied to the water heater

shall be adjusted such that the measured

electrical power input is 4275±75W

when the lower resistive element is

heating water. The water heater

instrumentation: six internal

thermocouples plus entering and

leaving water temperature

measurements and energy use, is to be

installed according to the standard

Department test and rating procedure.

The water heater thermostats are to be

replaced with manual controls operated

to turn off the upper element at 135 °F

and on at 115 °F based on the internal

thermocouple located closest to the

upper thermostat location. The lower

element shall be operated, as specified

by the heat pump manufacturer, but to

turn off and on at not lower than 110 °F

and 100 °F respectively (unless a new

thermostat is supplied specifically for

the purpose) based on the internal

thermocouple located closest to the

lower thermostat. The lower element

shall also be controlled to not operate

coincident with the upper element. The

purpose of the manual controls is to

simulate the normal thermostats, but

with improved repeatability. The heat

pump system shall be installed per the

manufacturers installation instructions.

Unless otherwise specified by the

manufacturer, the water heater is to be

installed in the indoor room, as is the

compressor section, if it is separate from

the outdoor unit. The water heater is to

be connected to the compressor section

with 15 feet of interconnecting tubing

(30 feet total for two lines), insulated

(both) with R4 insulation. The

refrigerant sections are to be connected

with a total of 25 feet of 3⁄4′′ insulated

vapor line and 25 feet of 3⁄8′′

uninsulated liquid line. The line lengths

between the compressor section and the

indoor coil shall be between 5 and 10

feet, with the balance of the 25 feet

connected between the compressor

section and the outdoor unit, with 10

feet located in the outdoor room.

Calculation of Seasonal Performance

Factors

The overall performance of the

integrated heat pump system shall be

expressed in terms of seasonal

performances. In addition to the

Seasonal Energy Efficiency Ratio (SEER)

and Heating Seasonal Performance

Factor (HSPF) currently required by the

Department, a Combined Cooling

Performance Factor (CCPF) shall be

calculated for the cooling season and a

Combined Heating Performance Factor

(CHPF) shall be calculated for the

heating season. These two combined

performance factors reflect the energy

efficiency of the heat pump when

providing both space conditioning and

CAS-RM-79-102 COMMENT 18
Federal Register / Vol. 60, No. 152 / Tuesday, August 8, 1995 / Notices 40361

domestic water heating. The CCPF

reflects the system’s performance during

the portion of the year that the outdoor

air temperature is above 65 °F and the

system will be providing space cooling

and/or water heating. CHPF deals with

the other portion of the year when the

outdoor air temperature is below 65 °F

and the system will be providing space

heating and/or water heating. Both

combined performance factors shall be

calculated by means of a bin analysis as

used for calculating the Heating

Seasonal Performance Factor as

described in 10 CFR Part 430, Subpart

B, Appendix M, ¶ 5.2. The only changes

to the actual referenced bin analysis are

to extend it to account for the water

heating functions, and to have it reflect

calendar hours in addition to cooling

and heating load hours, so that the

water heating load can be fully

accounted for.

The Seasonal Energy Efficiency Ratio

(SEER) shall also be calculated by

means of the bin analysis used for the

Heating Seasonal Performance Factor,

the CCPF and the CHPF. This is a slight

departure from the referenced

procedures method for calculating a

SEER for units with single-speed

compressors, but yields a nearly

identical result and provides a directly

comparable base for use in determining

energy savings associated with water

heating.

The Heating Seasonal Performance

Factor (HSPF) shall also be calculated in

the manner referenced above, with the

exception that it is based on seasonal

hours as opposed to fractional hours.

The Combined Cooling Performance

Factor (CCPF) shall be calculated using

the same general approach as presented

in the Department/ARI/ASHRAE

standards for non-water-heating

equipment. The procedure relates the

space cooling and water heating loads

and the performance of the heat pump

to outdoor air temperature. The output

of the heat pump is balanced against the

building and water heating load at each

outdoor temperature bin above 65 °F to

determine: (a) The fractional heat pump

operating time spent in each

temperature bin performing space

cooling only; (b) the fractional heat

pump operating time spent in each

temperature bin performing combined

space cooling and water heating; (c) the

fractional heat pump operating time

spent in each temperature bin

performing dedicated water heating; and

(d) the heat pump energy consumption

rate for each mode of operation for each

temperature bin.

The energy input to the domestic

water is assumed to be distributed by

temperature bin in proportion to the

total hours of occurrence per bin. The

performance of the heat pump by bin,

and by mode of operation, is based on

interpolation of test data taken at

representative operating conditions. The

total energy consumption of the heat

pump will be increased as a result of the

domestic water heating load. There will,

however, be a net energy savings, which

is expressed in terms of a Combined

Cooling Performance Factor for space

cooling and water heating, designated

CCPF. CCPF is the sum of the total

space cooling load and the total

domestic water heating load during the

cooling season, divided by the sum of

the total energy consumption used for

space cooling and water heating over

the same period, expressed in Btu/Wh.

The Combined Cooling Performance

Factor for space cooling and water

heating shall be calculated similarly to

the SEER:

LF(Test 4) = 0.5 = the load factor during

the 82 °F combined cooling/water

heating cyclic test.

The electrical power input to the heat

pump at the 82°F cyclic test point is

corrected (decreased) by the actual test

part load factor (PLF) in order to make

it consistent with the 95°F test point

which is steady-state. Later bin analysis

of energy use will interpolate between

the 82°F and 95°F points and have the

energy use for each bin increased by

that bins’ calculated PLF. This approach

of the 95°F test being continuous

compressor operation and the 82°F test

being cyclic is most representative of

actual field operation and provides the

most representative water side

conditions.

The performance of the heat pump in

dedicated water heating during the

cooling season is assumed constant

because the heat source is the constant

temperature indoor air. Because the test

is cyclic, the actual test results are again

corrected from the PLF of the test to the

PLF of each temperature bin in the

Data Reduction Notes for Table 1

1. Data recorded per ASHRAE

Standard 116–83.

2. Water heating capacity is calculated

as the net water energy withdrawn plus

the tank standby loss during the test

duration, divided by the length of time

that the water pump and/or auxiliary

water heater elements operate and

expressed as BTU/hr. Test duration is

defined as starting at t=0 and ending at

the conclusion of water heating from all

sources. Makeup and supply water

temperatures are to be recorded every 5

seconds during water draws.

3. The steady-state cooling or heating

capacity coincident with water heating

is calculated as the total air side

capacity delivered during the period of

time that the water pump and/or

auxiliary water heater elements operate,

divided by the length of time that the

water pump and/or auxiliary water

heater elements operate and expressed

as BTU/hr.

4. The cyclic cooling or heating

capacity coincident with water heating

is calculated as the air side capacity

delivered during the period of time that

both the water pump and indoor blower

and/or both the auxiliary water heater

elements and indoor blower operate,

divided by the length of time that both

the water pump and indoor blower and/

or both the auxiliary water heater

elements and indoor blower operate and

expressed as Btu/hr.

5. The cyclic cooling capacity

associated with dedicated water heating

is calculated as the air side capacity

delivered during the period of time that

the indoor blower operates, divided by

the length of time that the indoor blower

operates, and expressed as Btu/hr.

6. The power used with the cooling or

heating capacity associated with water

heating is calculated as the total energy

consumed by all components, including

the heat pump, water pump, and

auxiliary water heater elements, etc.,

during the length of time that the air

side capacity is integrated, divided by

the same length of time, and expressed

as Watts.

7. The power used with the dedicated

water heating capacity is calculated as

the total energy consumed by all

components, including the heat pump,

water pump, and auxiliary water heater

elements, etc., during the duration of

the test, divided by the period of time

used in determining the associated

water heating capacity determination.

The Assistant Secretary for Conservation and

Renewable Energy,

United States Department of Energy, 1000

Independence Avenue, S.W.,

Washington, DC 20585.

Subject: Petition For Waiver and Application

for Interim Waiver.

Gentlemen: This is a Petition for Waiver

and Application for Interim Waiver

submitted pursuant to Title 10 CFR 430.27,

as amended November 14, 1986. Waiver is

requested from the existing Test Method for

Measuring the Energy Consumption of

Central Air Conditioners, including heat

pumps as found in Appendix M to Subpart

B of Part 430.

Under the existing Test Procedure, heat

pump energy consumption is measured

relative only to space heating and cooling.

NORDYNE requests a waiver to the existing

test procedure as detailed in the attached

‘‘Requested Test and Rating Procedure

Modifications for Electrically Driven, SingleSpeed Compressor, Air-to-Air Heat Pumps

With Integrated Water Heating’’, for use in

the testing and rating of its Powermiser line

of heat pumps which include special design

characteristics to incorporate domestic water

heating.

The current test procedure clearly cannot

account for the energy savings associated

with integrated water heating.

NORDYNE is confident that a waiver will

be granted and requests that an interim

waiver be granted. NORDYNE’s confidence is

based on:

(1) The current test procedure does not

account for the total energy savings of the

Powermiser.

(2) Carrier Corporation has been granted a

similar waiver for its Hydrotech product.

(3) For public policy, the widespread use

of this type of integrated appliance would be

in direct support of the President’s Climate

Change Action Plan, which lists heating and

cooling and home appliances as key targets

for improvement.

(4) Absent a favorable determination on the

Application for Interim Waiver, NORDYNE

would experience an economic hardship, as

discussed in the confidential attachment.

Known manufacturers of domestically

marketed units of the same product type are

being notified in writing of this Petition for

Waiver and Application for Interim Waiver.

A list of the names and addresses of each

person to whom a notice is being sent is

attached.
