Background

• Energy Policy and Conservation Act (SPCA) of 1975

established an energy conservation program for major

household appliances (P . L. 94-163) 1

• Amendments to EPCA in the National Appliance Energy

Conservation Act of 1987 (NAECA) (P.L. 100-12)2

- Established:

• Prescriptive energy conservation standards for residential clothes

dryers; and

• Performance energy conservation standards for room air

conditioners

- Directed DOE to conduct two cycles of rulemakings for both

products to determine if more stringent standards are justified.

effective May 14, 1994. (56 FR 22250)

Second standards rulemaking initiated by publication of ANOPR

on November 14, 1994. (59 FR 56423)

Rulemaking activities suspended in FY 1998 due to the prioritysetting process outlined in Procedures, Interpretations and

Policies for Consideration of New or Revised Energy

Conservation Standards for Consumer Products ("Process

Rule"). (61 FR 36974)

• Room Air Conditioners

Procedures

Test Procedure - Residential Clothes Dryers

• DOE published a Final Rule for the dryer test procedure on May

19, 1981. (46 FR 27324)

• Manufacturers have informed DOE that the test procedure is

unable to test vent-less dryers due to the requirement of an

exhaust simulator.

• DOE proposed an alternate test procedure in 2006 for vent-less

dryers. (71 FR 49437, 49439)

• A final determination on the alternate test procedure has not yet

been made.

• DOE also seeks comment on amending the clothes dryer test

procedure to adequately measure effects of:

- Remaining moisture content (RMC);

- Average number of use cycles; and

- Automatic cycle termination

14

 EERE-2007-BT-STD-0010 COMMENT 04.5
Test Procedure - Room Air Conditioners

• DOE redesignated and amended its test procedure for room air

conditioners on June 29, 1979. (44 FR 37938)

• The test procedure cites two test standards that are each at least 25

years old:

- American National Standards (since renamed American National

Standards Institute (ANSI)) Z234.1-1972, "Room Air Conditioners"; and

- American Society of Heating, Refrigerating and Air-Conditioning Engineers

(ASHRAE) Standard 16-69, "Method of Testing for Rating Room Air

Conditioners".

• Both test standards have been updated to more recent versions, which

could be incorporated into the DOE test procedure by reference.

• DOE also seeks comment on amending the room air conditioner test

procedure to adequately measure effects of:

- Technologies that improve part-load performance; and

- Annual operational hours

15

 EERE-2007-BT-STD-0010 COMMENT 04.5
Request for Comment

Item 1 -1 DOE welcomes input from stakeholders on the merits of

revising its test procedures for residential clothes dryers to account

for lower-RMC clothes loads and fewer use cycles, add the

capability to test vent-less clothes dryers, and measure the benefits

of enhanced automatic termination systems.

Item 1 -2 DOE welcomes input from stakeholders on the merits of

revising its test procedures for room air conditioners to incorporate

by reference the most recent ANSI and ASHRAE test standards,

account for fewer annual operating hours, and add the capability of

measuring the impact of technologies that improve part-load

performance.

Request for Comment

Item 3-1 DOE welcomes input on information that would contribute to the

market assessment for residential clothes dryers and room air conditioners

covered in this rulemaking (e.g., current product features and efficiencies,

product-feature and efficiency trends, historical shipments, and prices).

32

 EERE-2007-BT-STD-0010 COMMENT 04.5
Definitions

Under EPCA, DOE provides definitions of clothes dryers and

room air conditioners (10 CFR 430.2):

"Electric clothes dryer means a cabinet-like appliance designed to dry

fabrics in a tumble-type drum with forced air circulation. The heat

source is electricity and the drum and blower(s) are driven by an electric

motor(s) ".

Gas clothes dryers are similarly defined, with gas as the heat source.

"Room air conditioner means a consumer product, other than a

"packaged terminal air conditioner", which is powered by a single phase

electric current and which is an encased assembly designed as a unit

for mounting in a window or through the wall for the purpose of providing

delivery of conditioned air to an enclosed space. It includes a prime

source of refrigeration and may include a means for ventilating and

heating. "

Equipment Product Classes

• DOE will formulate a separate energy conservation standard for

each product class.

• Separate efficiency levels will be considered for each equipment

class.

• DOE divides covered equipment into classes by:

The type of energy used

- Capacity of the equipment

Other performance-related features such as those that

provide utility to the consumer, or others deemed appropriate

by the Secretary that justify different standard levels, (42

USC 6295(q) and 6316(a))

Room Air Conditioner Product Classes

• NAECA initially specified 12 product classes applicable to units

designed for single- or double-hung window installation, based

on the following criteria (42 U.S.C. (c)(1)):

1. Cooling capacity

2. Presence of louvered sides (LS)

3. Capability of reverse cycle, in which the unit functions as a

heat pump

• The Final Rule, effective October 1, 2000, includes 4 additional

product classes.

Item 3-2 For both residential clothes dryers and room air

conditioners, DOE welcomes input from stakeholders on the proposed

product classes and the criteria used for creating these product

classes. Are there other considerations of which DOE should be

aware beyond those identified above as a basis for developing product

classes? If so, please explain (citing specific examples to the extent

possible).

Item 3-3 Specific to clothes dryers, DOE welcomes input from

stakeholders on its proposal to add vent-less clothes dryer product

classes, including combination washer/dryers.

Item 3-4 Specific to room air conditioners, DOE welcomes input from

stakeholders on its planned approach to analyze the three

representative product classes (i.e., without reverse cycle and with LS

with cooling capacity of less than 6,000 Btu/h, 8,000-13,999 Btu/h, and

20,000 Btu/h or more) and to subsequently numerically extend the
