The Energy Conservation Program for ConsumerProducts (other than automobiles) was establishedpursuant to the Energy Policy and Conservation Act (EPCA), (Pub. L. 94-163), 89 Stat. 917, as amended by the National Energy Conservation Policy Act (NECPA), (Pub. L. 

### 95-619), 92 Stat. 3266, the National Appliance Energy Conservation Act of 1987 (NAECA), (pub. L. 10!H2). and the National Appliance Energy Conservation AJnemlments of 1988 (NAECA 1988), (Pub. L. 100-357}.1. 

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

consumerproducts, including central air conditioners and central air conditioning heatpumps. The intent ofthe test procedures is to provide a comparable

measure ofenergy consumption that will assist consumers in making purchasing decisions. These test procedures appear at 10 CFR part430, subpart B.

DOE has amended the prescribed test procedures on September 26. lSBO, 

### by adding 10 CFR 430.27 creating the waiverprocess. 45 FR 64103. DOE further amended the Department's appliance test procedure waiverprocess to allow the Assistant Secretaryfor Conservation and Renewable Energy to grant an interim waiver from test procedure requirements to manufacturers thathave petitioned DOE for a waiver ofsuch prescribed test

### procedures. 51 FR 42823, November 26, 1986. The waiverprocess allows the Assistant Secretaryfor Conservation and Renewable Energy to waive temporarily test procedures for a particularbasicmodel 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 ofits 

### true energy consumption as to provide materially inaccurate comparative data. Waivers generally remain in effect until final test procedure amend.'l1ents become effective, resolving the problem thatis the subject ofa waiver.

The interim waiverprmrisions, added by 

### the 1986 amendment. allow the Assistant Secretary to grant an interim waiverwhen it

### is determined that the applicant will experience economic hardship ifthe Application for Interim Waiveris denied. ifit appears likely that the petition for waiver

### vvill be granted and/or the Assistant Secretary determines that it

### would be desirable for public policy reasons to grantimmediate reliefpending a determination on the petition for waiver.

Carrier seeks a waiverfrom the DOE
test provisions for central air conditioners and central air conditioning heatpumps for its HydroTech 2000 model heat pump. Carrier requests this reliefbecause. in addition to providing space heating and cooling, the HydroTech 2000 also provides domestic water heating. Carrier claims that while the HydroTech 2000 is capable ofbeing tested in accordance with the DOE central air conditioner test procedure for Seasonal Energy Efficiency Ratio (SEER) and Heating SeasonalPerformance Factor (HSPF), the test procedure does
not give a true representation ofthe enrgy consumption ofthe HydroTech 2000 heat pump. The HydroTech 2000 heatpump provides domestic water heating during the space cooling mode with the heatrejected from the house. The excess heating capacity ofthe heat PU.'IlP provides supplementary water heating during the space heating mode. When space conditioning is not required, the unit 

### operates in a water heating only mode. This results in reduced energy consumption for water heating, as compared to a standard twoelement electric resistance waterheater. Carrierrequests that the waterheating energy savings, compared to a conventional waterheater. should be applied to the HydroTech 2000's space cooling and heating performance. Carrierrequests the allowance to test and rate the HydroTech 2000 with an FE ""'f"" TT_


### equivalent SEER and an equivalent HSPF. The test procedure proposed by Carrieris based on the Department's
test procedure for central air conditioning heatpumps and would credit the unit's SEER 

### and HSPF with the reduced energy use for water heating.

Carrier also request an Interim Waiver from the central air conditioner
test procedure for the HydroTech 2000 

### heat pump, Carrier. in 

### the Application for Interim Waiver. states thatits Petition for Waiver will likely be granted since it

### includes a feature, water heating, that is not included in the existing central air conditioner and central air conditioning heatpump test procedure. Furthermore, Carrier claims that it

### is in the national interest for Ii 

### waiverto be granted, since without a waiver, Carrier will not

### be able to claim the electric energy savings capabilities ofthe HydroTech 2000, 

### and as a result, will lose sales which, in turn, 

### will result in increasednational energy consumption and the corresponding release ofgreenhouse gases. Finally; Carrier claims that it

### will experience economic hardship ifthe Application is denied since, Carrier estimates, it 

### will lose approximately $7 million in gross margin in the next three years.

DOE has reviewed Carrier's Petition for Waiver and agrees that the extant test procedures for central air conditioners and central air conditioning heatpumps evalutes the Carrier HydoTech 2000 heatpump in a manner unrepresentative ofita true energy consumption since it 

### does not consider the energy usage due to waterheating. However. the Departmentbelieves that the remedy proposed by Carrier. adjusted SEER and HSPF, are also not representative ofthe unit's true energy efficiency. SEER, HSPF, andEnergy Factor (EF) are measures ofefficiency that result from ratios ofenergy outputs and inputs for well-defined and separate space cooling, space heating and domestic waterheating processes. Ifit



### were possible to allocate the input energy separately to the space heating, space cooling and domestic water heating functions,**t.~en** 

### EF, SEER and HSPF could be calculated for L1.is unit 

### However, DOE believes this is not possible when two processes occur simultaneously. Therefore, DOE believes that to subtract an energy savings quantity for waterheating from the denominator ofan output/input ratio that applies to space heating or cooling artificially inflates SEER and AFUE and would notrepresent 

### hi-a efficiency ofthe HydroTech 2000 in either mode.

If, based on the evidence included in Carrier's Appliance for Interim Waiver, DOE

### wereto grant Camerrelieffrom the central air conditioner test procedure, it

### would be to waive the test procedure entirely. Doe believes that this is contrary to Carrier's intent since Carrier requested the waiver in order to make SEER andHSPF representations. Carrier claims thatnotbeing able to make representations ofequivalent SEER 

### and equivalent HSPF makes it difficult for consumers to "have a clear understanding ofthis product's energysaving 

### capability." Similarly, DOE 

### believes thatgranting outright relief from the test procedure would cause further hardships for Carrier since it 

### would be 

### unable to make either SEER or HSPF representations.

Therefore. based on the above. Carrier's Application for an Interim Waiveris denied. This is not 

### a determination, however, on Carrier's Petition for Waiver, which is being· published today for comment.

Carrierproposes 

### a test method

### based
on, to a signiflcant extent, the existing centralair conditioning and central air 

### conditioningheatpump test procedures. Forwaterheating. Camel'proposes two simulated use tests with an outdoor temperature of 17°F and 67°F with four water draws to simulate household
waterusage. For combined space cooling/domestic waterheating. Carrier proposes two tests, 67°F atlow compressor speed and 95°F at high compressor speed. For combined space heating/domestic water heating. Carrier iJfOpOSes that one cyclic test and one :steady-state test be performed at 17"F. These tests are presented in detail in Carner's Petition for Waiver andits proposed alternate testprocedure.

Pursuant to paragraph (b) of 10 CPR 430.27, DOE 

### is hereby publishing the "Petition for Waiver." Due to its length. Carrier's proposed alternate test procedure (of23 pages) (Attachment A), is not being publishedin 

### the Federal Register. It

In addition, pursuant to paragraph (e} of §

### AveJ'lue Sw., Washington. DC29585 Gentlemen: Re: Petition for Waiver orD.O.E. Test Procedures for Central Air Conditioners (Including Heat Pumps) as They Apply to the Carrier HydroTech 2000Series Heat Pumps Carner's newHydroTech 2000 heat pump is an innovative unit thathas a unique ability
to enhanceresidential

### ene..-gy conservation. The unit is the product of six years of research and developmentby Carrier and the ElectricPowerResearch Institute (EPRI). The unit was developed

### anddesigl1ed withone principal objective: significant energy conservation.

Our objective in this petition for waiveris
to 

### seek a modification to the procedurefor testing central ail' conditioners (including heatpumps). Because this productis 

### a heat
pump

### thatprovides domesticwaterheatingin addition to spaceheating and cooling, 

### a new and different procedureisrequired to rate this product accurately andin terms the

consumer canunderstand. We recognize that

we can test for the SeasonalEnergy EfficiencyRatio (SEER} and Heating Seasonal Performance Factor (HSPF) of this unitunder existingtest procedures, and the unit canbe ratedaccordingly.

.

However, these procedures do not describe
to consumers this heat pump'strue measure ofefficiency orgive credit for the water heating feature. Ourrecommended procedure, which is compatible withcurrent Department 

### ofEnergy test procedures for heatpumps and water heaters, is included in the attached documents "''ith supporting technical information. The procedure we are proposing can be used to test any central air conditioner or heat pump 

### that also heats domestic hot water, such as units which include desuperheaters.

The procedurebeing proposed is similar but not identical to one drafted by NIST at the request of

### DOE and EPRI. This similarity is in the data gaL':lering sections ofeach procedure, not in the way that data are applied to estabiishing systems efficiency**ratings~**

Specificaliy. the Carrierprocedures take less time, and mus are les3 cosily, yet an! felt
to provide sufficient data to develop 

### realistic system efficiency ratings. The detailed differences between L'lese two procedures

are pro\cided as Attachment A,l

Specifically. we request a waiver of test pn)ce'UUre3 to allow the HydroTech 2000 system to be tested and rated with an equkalent SeasonalEnergy Efficiency Ratio (SEER) 

### and an equivalent Heating Seasonal Performance Factor lHSPF) 30 that

consumers 

### will have a clear understanding 

### of this product'senergy-saving capability.

The Energy Policy and Conservation Act

was passed to conserve energy. This product is a quantum leap toward the goals set forth in thaa legislation. Energy conservation is

now even more important as the issue of

1 Attachment A is available upon request from DOE. global warming becomes a matter ofnational and international concern.

The recent history ofheat pump development in the United States reflects a steady progression towardmore energyefficient equipmentThe year 1974 brought widespread acknowledgement and acceptance of the single-speed heat pump's energy-conserving abilities.

Two-speed heat pumps in 1975 and variable-speed units in 1986increased energy conservationfurther.

Carner's new unit, the HydroTech 2000 system. now providesthe stepbeyond the energy-saving capability 

### ofvariable speed. By integrating domestic water heating, which
accounts for as much as one-thirdof th.e
energy used in 

### a home,energy-savings can be extendedasmuch as 20% beyond today's variable speedheatpumps.

Consumers will be able to recoup their hIgher initial investment in HydroTech 2000 quickly ilirough reduced energy bills. But again, they mustbe able to evaluate this new unit's energy-saving abilities in terms they understand.

The HydroTech 2000heat pump is a natural progression in the trend toward more energyefficient equipment. However, we must be able to present this new system's energy efficiency in II. way that is familiar and understoodby consumers so they can make rational comparisons. Therefore, we are requesting II. waiverand the ability to present this unit's efficiency in terms of equivalent SEER and HSPF, which are measurements and comparisons that consumers understand.

Ourrecommended approach to rating this

new system is as ioflows. Because the HydroTecn 2000 unit provides virtually free
waterheating during the cooling mode, and reduced energy consumption for water heating during the space heating mode and
water heating only modes, the resulting
energy-use reduction from that of conventional electric resistance heat water heaters shouldbe applied to the unit's space cooling and heating performance.

This is iIlustrated in Attachment B. In (1) the energy consumption of the HydroTech 2000 and its HSPF and SEER are shown when tesled as II. heat pump only without its water heating function included. Tne energy-use values shown for 

### DHW are based on the consumption ofa typical household electric resistance water heater. In {2} is shown total annual energy consumption for comfort heating and cooling 

### and water heating when tested as an integrated appliance. Here the reduction in ihe system's energy consumption (in kWh) is applied to water heating. Therefore, the HSPF and SEER remain the

same (9.0 and 14.0 respectively).

In [3J. however. the reduction in total
energy consu'{nption is applied to heating and cooling and not to waterheating. (Noie that the KWH of energy consuInption for domestic hot water is identical in scenarios 1 and 3.) Ther€fore,the unit's HSPF becomes 11.0 and its SEER becomes 20.4. These are the numbers that Carrier Corporation believes represent the system's true efficiencies and

are appropriate to present to the consumer.

Ithas been suggested that doliars (annual operating cost) be used as a comparative. No

### and electric operating costs ofgas-fired furnaces. AFUE is the generic comparative used to make gas furnace purchase decisions Just as SEER and HSPF are the descriptors used to judge comparative efficiency ofheat pumps.

As a nation. the United States is becoming increasL'1g1y concerned with energy conservation. the burning offossil fuels, and the greenhouse effect. The nation has also been concerned that A."i1erican corporations

are taking the short-term approach to the future and are not investing for the long term.

Carrier Corporation, through its new HydroTech 2000 unit.

A waiver

Attachment A-ComparisonWith NIST Draft Report

The testi!1g and rating procedure ff1commended by Carrier Corporation are similar to those recommended in a recent 

### MSTproject which addresses the same type of equipment.



### The results ofthe NIST study have been compiled into a draft report by Brian Dougherty entitled "A Proposed Methodology for Rating Air-Source, integrated Heat Pump! \'V;:;\er Heating Appliances having Combined aIld Dedicated Water Heating". which 

### wiil be publ.lshed in the near future as a NISTIR report. Although t·aST project was d'Jne in.oepend:::ntly. the results 

### are similar to those in the Carrier proposaL

mfferences between the hvo proposals 

### exist in two areas: (1J The type and number oftests, and {2) the merhod01ogy for deriving 

### L'1e.rating descriptors. The**principc:~** , 

### C'lflct€nCescan be 

### SU.1--:nmal'12ed as lodows:

1. TestP')ints, NIST. like Carrier. proposes two simulated 

### ,lse tests (dynamic drew testsj. N!ST proposes tests at ourdoo, temperatures of'17F and 82F; Carrie!' proposes 17F and 67F bac:al1se we feel that these better cover the wide runge of water heating capacities. NIST
proposes a slngle draw. Carrierpropos€1i!a

more comulex 4-draw schedule which is more representative oftypical households, For the combined space cooling/DBINmode. Carrier
proposes .2 tests which cover the range of operation in this mode. 67F with low
compressor speed and 95F with high
compressor speed. with a simple H rmErms

interpolation between these two points. NIST added two more intermediate points at 82F in order to cover the shiftbetween desuperheating and 

### full condensing water heating. Although these extra points would better describe the system performance, we do not believe that the net effects would justify the added testing and analysis burden. For the combined space heat!DHW mode. Carrierproposes that one cyclic test and one steady 

### state test

### be performed at 17F representing systemperformance at a lower DHW capacity is low (It is higher in all other tests). NISThadproposed these tests at 47F only.



### 2. Methodology. 

### Both proposals use temperature bin type procedures. NIST
averages the daily DHW load (converted to BTUs) evenly over a 24 hour period. resulting in a low lORd {IllS!! than 2000 BTU/hour). We feel that this 

### will over-estimate the capabilities of

### an integrated Dffi'V unit, especially low-capacity. desuperheating-oruy types. since DHW loads are normally discrete and require quick responses with capacities comparable to 4.5 kW (15358 BTU/ hr) tank heater elements. 

### Ifheatpump equipment has lower capacities, the auxiliary elements will be used 

### Ifthe load is always low. the use ofauxiliary elements will be under-estimated. Carrierproposes splitting the typical day intQ two parts-an active draw period (all draws. high BTU/hrloads) and 

### a standbyperiod (no draws. low 

### BW/hr loads).

Concerningrating and reporting descriptors, Carderproposes the use of equivalent SEER and HSPF factors, which combine the system energy savings eccrued in all operating modes, into factors (SEER and f ISPFl which are universally accepted and understood by both manufacturers and purchasers 

### ofheat pump equipment.
