SUPPLEMENTARY INFORMATION: 

I. Background and Authority 

II. Petition for Waiver 

III. Application for Interim Waiver 

IV. Alternate Test Procedure 

V. Summary and Request for Comments 

I. Background and Authority 

Title III of the Energy Policy and 

Conservation Act (EPCA) sets forth a 

variety of provisions concerning energy 

efficiency. Part C of Title III (42 U.S.C. 

6311–6317) provides for an energy 

efficiency program entitled ‘‘Certain 

Industrial Equipment,’’ and includes 

commercial air conditioning equipment, 

packaged boilers, water heaters, and 

other types of commercial equipment. 

Today’s notice involves commercial 

equipment under Part C, which 

specifically provides for definitions, test 

procedures, labeling provisions, energy 

conservation standards, and the 

authority to require information and 

reports from manufacturers. With 

respect to test procedures, Part C 

generally authorizes the Secretary of 

Energy to prescribe test procedures that 

are reasonably designed to produce 

results which reflect energy efficiency, 

energy use and estimated operating 

costs, and that are not unduly 

burdensome to conduct. (42 U.S.C. 

6314(a)(2)). 

For commercial package air 

conditioning and heating equipment, 

EPCA provides that the test procedures 

shall be those generally accepted 

industry testing procedures or rating 

procedures developed or recognized by 

the Air-Conditioning and Refrigeration 

Institute (ARI) or by the American 

Society of Heating, Refrigerating and Air 

Conditioning Engineers (ASHRAE), as 

referenced in ASHRAE/IES Standard 

90.1 and in effect on June 30, 1992. (42 

U.S.C. 6314(a)(4)(A)) This section also 

provides for the Secretary of Energy to 

amend the test procedure for a product 

if the industry test procedure is 

amended, unless the Secretary 

determines that such a modified test 

procedure does not meet the statutory 

criteria. (42 U.S.C. 6314(a)(4)(B)) On 

October 21, 2004, DOE published a 

direct final rule, effective December 20, 

2004, adopting ARI Standard 210/240–

2003 for small commercial package air 

conditioning and heating equipment 

with capacities < 65,000 Btu/h and ARI 

Standard 340/360–2000 for large 

commercial package air conditioning 

and heating equipment with capacities 

≥ 135,000 Btu/h and < 240,000 Btu/h 

and small commercial package air 

conditioning and heating equipment 

with capacities ≥ 65,000 Btu/h and < 

135,000 Btu/h. 69 FR 61962, October 21, 

2004. According to Cascade, both ARI 

Standard 340/360–2000 and ARI 

Standard 210/240–2003 are applicable 

to Cascade’s Cascade Energy Saver 

(CES) products. However, Cascade only 

seeks a waiver from ARI Standard 210/ 

240–2003. 

DOE’s regulations set forth under 10 

CFR 431.401 contain provisions 

allowing a person to seek a waiver from 

the test procedure requirements for 

commercial equipment. The waiver 

provisions allow the Assistant Secretary 

for Energy Efficiency and Renewable 

Energy (hereafter ‘‘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 either 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. 10 CFR 431.401(a)(1). 

The Assistant Secretary may grant the 

waiver subject to conditions, including 

adherence to alternate test procedures. 

10 CFR 431.401(f)(4). Petitioners are to 

include in their petition any alternate 

test procedures known to evaluate the 

basic model in a manner representative 

of its energy consumption. 10 CFR 

431.401(b)(1)(iii). Waivers generally 

remain in effect until final test 

procedure amendments become 

effective, thereby resolving the problem 

that is the subject of the waiver. 10 CFR 

431.401(g). 

The waiver process also allows the 

Assistant Secretary to grant an interim 

waiver from test procedure 

requirements to manufacturers who 

have petitioned DOE for a waiver of 

such prescribed test procedures. 10 CFR 

431.401(a)(2). An interim waiver 

remains in effect for a period of 180 

days or until DOE issues its 

determination on the petition for 

waiver, whichever is sooner, and may 

be extended for an additional 180 days, 

if necessary. 10 CFR 431.401(e)(4). 

II. Petition for Waiver 

On July 22, 2005, Cascade filed the 

Cascade Petition for Waiver and its 

Application for an Interim Waiver from 

the test procedures applicable to 

commercial package air conditioning 

and heating equipment. On May 26, 

2006, Cascade filed an amended Petition 

for Waiver listing all the basic models 

for which Cascade seeks a waiver. In 

particular, Cascade requested a waiver 

from the commercial test procedures 

contained in ARI Standard 210/240–

2003 for the system combinations listed 

in Table 1, attached to its amended 

Petition. 

Cascade seeks a waiver from the test 

procedures in ARI Standard 210/240–

2003 and asserts that the design 

characteristics of the CES systems 

prevent testing according to these 

prescribed test procedures. In particular, 

Cascade states that the CES indoor-coil 

blower models have more than one 

blower per coil and up to and as many 

as eight blowers that operate 

independently. Cascade claims that its 

products do not conform to the test 

procedures in ARI Standard 210/240–

2003, because these test procedures are 

based on a system with only one indoorcoil blower. 

Cascade asserts that with slight 

modifications to ARI 210/240 

procedures, CES units can be tested and 

that such testing can provide 

measurements to satisfactorily 

determine the Seasonal Energy 

Efficiency Ratio (SEER) and the Heating 

Seasonal Performance Factor (HSPF). 

Cascade included in its petition sample 

SEER calculations, sample test 

procedures used to derive the SEER 

calculations, and sample test data. The 

testing, contracted by Cascade to Texas 

A&M University Energy Services 

Laboratory (hereafter ‘‘TAMU–ESL’’), 

provides data on a system with two 2.5- 

ton Amana RHF 030 heat pump units of 

SEER 12 connected to a dual-circuit 

evaporator coil, followed by a plenum 

housing 8 blowers operated by a control 

system. Using a test procedure based on 

ARI 210/240, TAMU–ESL calculated a 

SEER value of 18.1 and an HSPF of 9.5. 

Details of the testing are provided in the 

Cascade Petition, published in full, 

below. 

III. Application for Interim Waiver 

Cascade also requested immediate 

relief through its Application for Interim 

Waiver to avert undue economic 

hardship. According to DOE regulations, 

an interim waiver may be granted if 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 


sroberts on PROD1PC70 with NOTICES
Federal Register / Vol. 72, No. 76 / Friday, April 20, 2007 / Notices 19893 

1For example, according to a 450 cfm/ton 

requirement, a 5 ton unit would be permitted to 

have an airflow rate of 2,250 cfm or lower. If that 

system were to operate at 2,000 cfm and have 8 

fans, each fan would blow 250 cfm. In addition, if 

that same system were to operate at partial load 

with 2.5 tons of capacity, the tester could operate 

4 fans with each fan blowing 250 cfm. 

2For example, section 6.1.3.3 requires equipment 

with indoor fans intended for use with field 

installed duct systems to be rated at the indoor-coil 

airflow rate of equal to or less than 37.5 SCFM per 

1,000 Btu/h of rated capacity. 

pending a determination of the petition 

for waiver. 10 CFR 431.401(e)(3). 

Cascade’s Application for Interim 

Waiver does not provide sufficient 

information to evaluate what, if any, 

economic impact or competitive 

disadvantage Cascade will likely 

experience absent a favorable 

determination on its application. It also 

does not provide sufficient information 

to determine if there are public policy 

reasons to grant immediate relief. 

Furthermore, DOE has never granted a 

previous waiver for a similar product 

design. Thus, the likelihood of granting 

the waiver is unclear until further 

information and comment is provided. 

Therefore, Cascade’s Application for 

an Interim Waiver from the DOE test 

procedure for its CES products is 

denied. Hence, it is ordered that: The 

Application for Interim Waiver filed by 

Cascade is hereby denied for Cascade’s 

CES air conditioners and central air 

conditioning heat pumps. 

This denial of Cascade’s Application 

for Interim Waiver is based upon the 

presumed validity of statements and 

allegations submitted by the company. 

This denial of Interim Waiver may be 

modified if DOE receives information 

that justifies granting an Interim Waiver. 

IV. Alternate Test Procedure 

DOE will make its judgment on the 

Cascade Petition after the period for 

public comment ends. However, should 

DOE grant Cascade a waiver from the 

applicable test procedures, DOE would 

likely prescribe an alternate test 

procedure. Manufacturers face 

restrictions with respect to making 

representations about the energy 

consumption and energy consumption 

costs of products covered by EPCA. (42 

U.S.C. 6314(d)) Consistent 

representations are important for 

manufacturers to make claims about the 

energy efficiency of their products. For 

example, they are necessary to 

determine compliance with state and 

local energy codes and regulatory 

requirements, and can provide valuable 

consumer purchasing information. 

Therefore, DOE is considering an 

alternate test procedure for Cascade. 

DOE is publishing the proposed 

alternate test procedure in this notice to 

account for the potential need for an 

alternate test procedure and to allow the 

public to comment on a proposed 

alternate test procedure. 

Cascade included a description of an 

alternate test procedure and test data for 

a sample system in its Petition. DOE is 

considering prescribing an alternate test 

procedure that takes into account the 

information Cascade provided in the 

petition. In particular, the proposed 

alternate test procedure would require 

Cascade to test units according to ARI 

Standard 210/240–2003, but permit 

Cascade to use alternate requirements 

when testing systems that have multiple 

fans per indoor coil.1 Cascade may test 

systems with multiple indoor fans that 

jointly provide the total indoor-coil 

airflow rate required for the capacity 

being tested, however, Cascade would 

be required to adhere to the airflow 

requirement of section 6.1.3.3 of ARI 

Standard 210/240–2003, which sets an 

upper limit on indoor-coil airflow 

according to system capacity.2 During 

testing, the individual indoor fans 

would each deliver an equal portion of 

the total required airflow. 

DOE generally agrees with TAMU–

ESL’s testing and analysis of a system 

with a CES 5-ton, 8-zone unit connected 

to an Amana RHF030 heat pump with 

a SEER of 12–14. As each Amana 

RHF030 heat pump uses a single-speed 

compressor, DOE agrees with TAMU–

ESL’s choice to treat the system as a 

two-speed blower with a two-stage 

compressor and test the system 

according to A2.2.2 and A2.1.3. 

Furthermore, DOE agrees with TAMU–

ESL’s decision to ensure a total indoorcoil airflow rate of around 2,000 cfm 

with eight blowers providing 250 cfm 

each, when operating the system at a 

full capacity. For low-speed conditions, 

TAMU–ESL operated the system at a 

2.5-ton capacity and ensured a total 

indoor-coil airflow rate of around 1,000 

cfm, with four blowers providing 250 

cfm each. 

However, it is not clear why TAMU–

ESL conducted Test C for full load 

operation only, though section A3.1.3 

indicates that if one chooses to perform 

Test C, the system must be tested at lowspeed. Furthermore, for certification, 

testing conditions must fall within the 

applicable tolerances provided in ARI 

210/240–2003. Finally, while DOE 

generally approves of the TAMU–ESL 

method to test a CES multi-blower unit 

paired with two Amana RHF030 heat 

pumps, DOE would expect Cascade to 

test its units according to those 

appropriate tests, procedures and 

conditions generally stated in ARI 210/ 

240–2003. For example, testing of a CES 

unit paired to a variable-speed 

compressor should follow the 

procedures and requirements described 

for a system with a variable-speed 

compressor in A2.1.6. 

Given consideration of the 

information provided to DOE in the 

Cascade Petition, DOE is considering 

the following alternate test procedure: 

Alternate test procedure. Cascade 

shall be required to test the products 

covered under this Waiver according to 

the prescribed tests, conditions, and 

procedures referenced in ARI Standard 

210/240–2003, except that Cascade shall 

be permitted to test systems with indoor 

units that have multiple fans. As such, 

Cascade shall be required to meet the 

usual indoor-coil airflow rate 

requirements of ARI Standard 210/240–

2003, section 6.1.3.3. However, tested 

units may run multiple indoor-coil fans 

which collectively meet the required 

indoor-coil airflow rates per capacity. 

To determine the level at which to 

operate the indoor fans during testing, 

Cascade may divide the total indoor-coil 

airflow rate at full load, by the number 

of indoor fans in the tested system. 

During testing, Cascade shall run the 

indoor fans at this level, and may decide 

how many indoor fans to operate by 

dividing the total indoor-coil airflow 

required at the capacity being tested by 

the indoor fan level, as determined 

above. Cascade may make 

representations of the CES products 

covered in this Waiver, consistent with 

the provisions outlined in this alternate 

test procedure. 

V. Summary and Request for Comments 

Today’s notice announces the Cascade 

Petition for Waiver and denies 

Cascade’s Application for Interim 

Waiver from the test procedures 

applicable to Cascade’s CES air 

conditioner and heat pump units. DOE 

is publishing the Cascade Petition for 

Waiver in its entirety. The Cascade 

Petition contains no confidential 

information. Furthermore, today’s 

notice includes an alternate test 

procedure that the DOE is considering 

including in the subsequent Decision 

and Order, should DOE decide to grant 

Cascade a Waiver. 

DOE is interested in receiving 

comments on all aspects of this notice. 

DOE is particularly interested in 

receiving comments and views of 

interested parties concerning whether to 

grant the Cascade Petition and regarding 

the proposed alternate test procedure. 

Specifically, DOE would like to receive 

comment on the following questions: 

• Does this alternate test procedure 

adequately specify how to handle 


sroberts on PROD1PC70 with NOTICES
19894 Federal Register / Vol. 72, No. 76 / Friday, April 20, 2007 / Notices 

airflows when testing a system with 

multiple blowers? 

• In the proposed alternate test 

procedure, fans are to run at a set cfm 

per fan throughout a test. Is this 

appropriate or should DOE allow fans to 

run at different cfm’s throughout a test 

while still meeting the required overall 

indoor-coil airflow rate according to 

capacity? 

• Cascade states that the current test 

procedure is not specific about the 

method of configuring a dual-circuited 

evaporator coil to blowers. However, 

Cascade does not propose specific 

language. Does the alternate test 

procedure proposed in this notice need 

to specifically address configurations of 

dual-evaporator coils and coil-blowers? 

• DOE is interested in receiving 

general comments on possible 

modifications to any test procedures or 

alternative rating methods that DOE 

could use to fairly represent the energy 

efficiency of Cascade’s CES products. 

Any person submitting written 

comments must also send a copy of 

such comments to the Petitioner, whose 

contact information is cited above. 10 

CFR 431.201(d)(2).

Design Characteristics Constituting the 

Grounds for Petition 

The United States Department of 

Energy has designated the American 

Refrigeration Institute (ARI) as the body 

of air conditioning industry partners to 

develop and maintain standards for 

compliance to the National Appliance 

Energy Conservation Act of 1987 

(NAECA). (10 CFR 430). The two 

standards that were developed by ARI 

that are applicable to the CES are the 

ARI 210/240 and ARI 340/360. 

ARI 210/240 is the standard that 

certifies the performance of units that 

are 65,000 Btu/hr or less. Currently, this 

standard requires that a split system 

heat pump meet a minimum SEER of 10. 

The standard also stipulates that it meet 

the maximum standard airflow rate of 

37.5 CFM/1000Btu/hr. This CFM is 

assumed to be applicable to the indoor 

unit that has only one blower-motor. 

The CES unit does not fit this model in 

that the indoor blower-motor 

combinations can range from 2 to 8 

indoor blower-motors that are 

independently operating. Thus a waiver 

is sought since the current procedures 

for testing do not apply. 

This request for a waiver will include 

SEER calculations that are the result of 

live data for a multi-indoor blowermotor configuration, those specific 

procedures followed during the test, the 

data in the test were conducted by the 

Texas A&M University Energy Services

Laboratory (TAMU–ESL) by Michael 

Davis under the supervision of Dr. 

Dennis O’Neal, Dean of Mechanical 

Engineering, Texas A&M University. 

The following results show that under 

ARI 210/240 conditions, connecting the 

CES 5ton-8 zone unit to an Amana 

RHF030 heat pump with an SEER of 12–

14 (dependant on the indoor blower-coil 

for the rating) produced an SEER value 

based on the calculations of 18.1 and an 

HSPF of 9.5. This is a 29% savings on 

cooling Seasonal energy efficiency Ratio 

and a 19% increase over the heating 

seasonal efficiency ratio. 

The ‘‘Results of Heating and Cooling 

Performance Testing of Cascade Energy 

SaverTM’’ report from Texas A&M is 

attached in the Appendix A. 

Specific Requirements Sought To Be 

Waived 

Cascade requests a waiver by this 

petition from the procedures of ARI210/ 

240 for models that are 65000Btu/h and 

smaller because the Cascade 

Manufacturing indoor blower coil 

models have more than one blower per 

coil and up to and as many as eight 

blowers. Thus, it does not conform to 

the test procedures of ARI 210/240, 

which are based solely on one single 

indoor-coil blower. We have proven 

with laboratory tests that an enhanced 

multi-blower fan coil is efficient and 

that by slight modifications to the 

current ARI 210/240 procedures, 

Cascade Energy Saver units can be 

tested and the results will show that the 

SEER and HSPF are easily measurable. 

Pursuant to the purchase of the CES, 

Cascade seeks to be a viable and 

profitable business concern and therefor 

desires to implement its business plan 

for manufacturing and distribution of 

mass quantities of the CES units in the 

various models and sizes to the general 

public within the United States. To 

effectuate the manufacturing and 

distribution, Cascade has entered into 

certain agreements with United Chester 

Industries, Inc. dba United Mechanical, 

Inc., an existing mechanical contractor 

with manufacturing and distribution 

capabilities. 

Cascade seeks immediate relief 

through this waiver to avert undo 

economic hardship. 

Discussion in Details for the Requested 

Waiver 

Concerning ARI 210/240 

1. The ARI 210/240 test procedure 

does not take into account indoor 

blower coils with more than one indoor 

blower and motor. The Cascade Energy 

Saver indoor coil-blower is thus a 

deviation from the ARI 210/240 model. 

This design is what Cascade believes 

will be product to fill a market niche 

and that the consumer with find huge 

energy saving benefits. 

Cascade contracted with TAMU–ESL 

to perform the ARI 210/240 testing 

comprised of two operating conditions, 

namely with 2 variations/combinations 

of indoor blowers and outdoor heat 

pumps, in order to demonstrate that the 

efficiencies are within the acceptable 

values of the NAECA, namely, SEER, 

COP, HSPF. 

2. In addition to the data, the 

assumptions, the test conditions, the 

procedures followed by TAMU–ESL are 

all included in the report from TAMU–

ESL. 

3. These procedures are the means by 

which the Cascade CES units will meet 

the standards as set forth by the NEACA 

of 1987. Once reviewed by DOE or its 

assigns, we assert that the test 

procedures presented herein can be 

incorporated into the ARI 210/240 as an 

approved manner to test multi-blower 

coil assemblies like the Cascade Energy 

Saver. 

4. It is Cascade’s intention to 

cooperate with DOE or its assigns, in 

rigorously supporting the data presented 

herein, the procedure as detailed by 

TAMU–ESL, our laboratory, the 

efficiencies reported and the 

conclusions. 

5. Cascade Manufacturing believes 

that the benefits to the consumer in the 

future usage of this CES unit will be 

dramatic in terms of reducing energy 

consumption which is the intent of the 

NAECA. 

Identification of Manufacturers With 

Similar Design Characteristics 

There are no other known 

manufacturers or products that are like 

the CES. This is the patented feature of 

the CES. The fact that the CES using 

multiple blowers is what creates the 

problem with the standards as noted 

previously in this Petition. 

Alternative Test Procedures To 

Evaluate Energy Consumption 

Characteristics 

• Cascade Manufacturing entered into 

a testing contract with Texas A&M 

University’s Energy Services Laboratory. 

The procedure that TAMU–ESL 

followed was the ARI 210/240 

procedure. TAMU–ESL ‘‘modeled’’ the 

Cascade system as a 2 speed blower and 

the compressors with 2 stages. 

• Thus, TAMU–ESL’s procedure was 

to collect data under the Tests A,B,C 

and D with all 8 blowers running 

(modeled as a single blower) and both 

compressors running (modeled as a 

single 2 speed compressor) and this is 

a full load case. Then, part load 

conditions were 4 blowers operating 

(modeled as a low speed single fan) and 

one compressor operating (modeled as a 

single compressor in low speed). 

• The CES unit had a 5 ton evaporator 

coil, split 50%/50% in the sense that it 

has a 4 row slab coil with 2 of the rows 

being connected to one 2.5 ton heat 

pump and the other two rows connected 

to the other 2.5 ton heat pump. The slab 

coil is patented in its design. It is a face 

split. Rows 1 and 3 are connected to one 

heat pump and rows 2 and 4 are 

connected to the other heat pump. The 

coil surface stays wet with one or both 

of the heat pumps operating. 

• When the full load test was 

conducted, all 8 fans were on. The 8 

fans are powered by individual 1⁄3hp GE 

ECM motors which use 50 watts of 

power each, thus 400 watts total for all 

8 fans. Each fan was set to blow only 

250 cfm at 0.5′′ ESP, for a total of 2000 

cfm (i.e., 5 tons of air). The outlet from 

each of the 8 zones was ducted with flex 

into a single 16′′ header. The 16′′ header 

was then ducted into the wind tunnel. 

• During the part load test, only four 

zone blowers were operating. Each of 

these four blowers was delivering 250 

cfm at 0.5′′; ESP, for a total of 1000 cfm 

which is the 400 cfm per ton for 2.5 

tons. The ducting was the same as in 

full load. 

• Tests A,B and C were run in 

accordance with the ARI210/240 

procedure and pursuant to the notes 

summarized above. Test D was not run 

since we chose to use the default 

coefficient of degradation of 0.25. 

• Finally, it is evident to me from 

these results that the ARI 210/240 

procedures worked for the Cascade unit. 

Further, the procedure can and should 

be evaluated by the industry bodies that 

are responsible for code enforcement to 

implement changes accordingly to allow 

for testing of Cascade units.

Executive Summary 

Cascade Manufacturing, LP (CM) 

contracted with the Energy Systems 

Laboratory (ESL) to conduct heating and 

cooling rating and performance tests on their 

multizoned coil blower unit called, ‘‘Cascade 

Energy Saver’’ (CES) in accordance with the 

ARI Standard for Air Source Split system 

heat pumps. The equipment tested consisted 

of one CES unit with 8 blowers, one Aspen 

5 ton Coil model # BHA40 60+x3 50/50SP (a 

two circuit slab coil with TXVs, 2.5 tons per 

circuit), and two Amana 2.5 ton Heat pump 

model RHF 030—12 SEER. 

At the time that this report was written and 

the tests were conducted, the ARI 210/240 

(Standard) was not clear with a procedure for 

the proper rating and performance tests for 

an HRCU–A–CB with multiple-zone blowers 

as manufactured by CM. In order to obtain 

laboratory data that would support an SEER, 

HSPF, COP and EER determination, ESL 

determined to follow and apply the 

Standard’s HRCU–A–CB as closely as 

possible (exceptions, deviations and 

assumptions to follow in this document). It 

appeared to ESL engineers that the Standard 

could be applied to the performance ratings 

of a CES unit when fixed indoor blower fan 

speeds were used in combination with (1.) 

traditional 400 cfm per ton and (2.) various 

compressor combinations. Before describing 

the application of the Standard, a description 

of the CES unit will be given in order for the 

reader to understand the logic behind the 

application of the Standard. 

The CES unit consists of two heat pump 

units connected to an evaporator that has two 

refrigerant circuits. The evaporator is 

followed by a plenum which houses multiple 

blowers that are independently operated by 

a control system developed specifically for 

the blower/evaporator/heat pump system. 

When in normal operation, the control 

system manages the operation of the 

compressors and fans in order to meet the 

system load as dictated by the multiple 

thermostats connected to the controller. The 

blower motors are variable speed motors 

manufactured by GE, model 2.3 ECM that can 

be operated at full capacity during peak 

operation or scaled back to lower rotational 

speeds at part load conditions. With the 

lower rotational speeds, lower cfm rates can 

be delivered independently to each zone 

connected to the system. 

The heat pump condenser units are off-theshelf units and are not manufactured by 

Cascade Manufacturing, rather their design 

permits the use of any manufactured unit 

from companies such as Amana Trane, 

Carrier, Lennox, or others. For our tests, we 

were supplied with Amana Heat Pumps. The 

heat pumps were operated in either an on or 

off mode and each one had single speed 

compressors and single speed fans. The fact 

that there are two heat pumps of equal size 

providing the two stages of cooling and 

heating with up to 8 indoor fans in a draw 

thru configuration to the dual circuit 

evaporator coil was the primary reason for 

selecting the specific guidelines from the 

Standard. The Standard gives detailed 

instructions for a variety of compressor 

operation combinations but it does not 

adequately describe various combinations of 

indoor fan(s) and two evaporator/compressor 

combinations possible with this unit. It was 

decided that the standard descriptions where 

the title included ‘‘units with two-speed 

compressors, two compressors, or cylinder 

unloading’’ most closely matched the 

operation of the CES unit. Typically units 

with two compressors also have separate 

refrigerant circuits on both the indoor and 

outdoor coils which match the configuration 

of the CES unit. 

The two major differences with this system 

in light of the Standard was how to apply the 

Standard to (1.) a coil blower unit with a 4 

row, dual circuited evaporator coil which is 

circuited with full face of the 1st and 3rd 

rows on one heat pump and rows 2 and 4 on 

the second heat pump, (2.) more than one 

evaporator blower. The coil blower unit 

tested had 8 blowers. The Standard does not 

describe how to handle the various air flows 

that can be produced with eight blowers. It 

was determined that the best way to test the 

unit was to apply full-load air flows as 

determined by nominal 400 cfm per ton 

(compressor) operation. For example, if both 

2.5 ton heat pumps were operating, the rated 

air flow that was tested was 2,000 cfm. With 

one heat pump running, the coil blower unit 

would have half the heating/cooling capacity 

therefore the full load air flow would be 

1,000 cfm which is half of the two heat pump 

supply side air flow. This interpretation of 

the Standard was used for both heating and 

cooling tests. 

For cooling, testing was done following the 

guidelines in ARI 210/240 section A2.1.3. 

Tests A, B, and C were conducted for both 

single heat pump and two heat pump 

operation. Test D was not done and the 

default CD of 0.25 was used for SEER 

calculations. The indoor air-enthalpy method 

was used during the tests. A description of 

the test facilities and the energy balance 

method is included below. Proper energy 

balances were achieved for all tests as were 

within the specifications of the standard. The 

results of the cooling tests are included in the 

table below. 

For heating, testing was done following the 

guidelines in ARI 210/240 section A2.2.2. 

Tests were conducted at 62F (one heat 

pump), 47F (one and two heat pumps), 35F 

(one and two heat pumps), and 17F (two heat 

pumps). The indoor air-enthalpy method was 

used during the tests. Proper energy balances 

were achieved on all test except the 17F test. 

Due to the cycling of the heat pumps between 

heating and defrost, two phase transients in 

the refrigerant circuit prevented a good 

measurement of the refrigerant flow until the 

unit reached steady state. The period of time 

where the refrigerant was in two phases was 

sufficient to prevent a proper energy balance 

from being achieved. The air-side 

measurements were taken with the same 

instrumentation during the 17F tests as were 

used during all other testing. It is reasonable 

to assume the air side measurements were 

accurate during the 17F tests since proper 

energy balances were achieved during all 

other tests. The results of the heating tests are 

included in the table below.

Facilities and Procedure 

All of the tests were conducted in the 

psychrometric rooms at the Energy Systems 

Laboratory which is part of the Texas 

Engineering Experiment Station a division 

within the Texas A&M University System. 

These rooms were completed in 1986 and 

have been used for research projects and 

industry testing. The rooms were designed 

for testing of systems with cooling capacities 

up to 10 tons. Chilled water is provided to 

the rooms by a 75 ton Trane screw chiller. 

Reheat is provided by 40 kW of electrical 

strip heaters in the conditioning ductwork. In 

addition, a desiccant system is used to 

provide low humidity conditions in either 

room. The psychrometric rooms allow indoor 

and outdoor dry-bulb and wet-bulb 

temperatures to be maintained within 

approximately ± 0.3 °C (0.5 °F) during steady 

state operations. Temperatures from 17 °F to 

120 °F have been maintained for tests in the 

rooms for previous tests. The rooms are 

capable of running all standard ARI 210/240 

(ARI 2003) and ASHRAE 37/116 (ASHRAE 

1988 and 1983) unitary heat pump and air 

conditioners tests, which include both 

heating and cooling mode. 

Electric resistance heaters and chilled 

water coils are used to maintain room 

temperature. Reheat in each room is provided 

by four banks of 9.9 kW electrical strip 

heaters in the conditioning ductwork. The 

cooling coil is supplied with a water ethylene 

glycol solution from the chiller. A 1000 

gallon water storage tank is mounted in the 

system to stabilize the chilled water 

temperature and reduce the cycling of the 

chiller. Steam from an electric-fired boiler 

and dehumidification coils control the 

humidity in the rooms. The dehumidification 

coils are fed from the same cool storage tank 

as the cooling coils. The boiler supplies 

steam directly into the supply air duct. Room 

temperature is maintained by adjusting the 

chilled water flow to coils with VSD driven 

pumps in combination with the operation of 

the reheat coils. 

The indoor test section includes the indoor 

air flow chamber and the indoor fan coil 

section. The air flow chamber fan draws 

conditioned air from the indoor room 

through the indoor test section. An adjustable 

damper is used to maintain the amount of air 

flow specified for each unit. After leaving the 

air flow chamber, conditioned air is routed 

back into the indoor room. Figure 1 shows a 

sketch of the indoor and outdoor rooms as 

used for these tests. 

The outdoor room section is the 

condensing sections for the heat pump units 

(compressors and outdoor coils) plus the 

outdoor airflow chamber. Conditioned 

outdoor air enters the outdoor coil and is 

exhausted to the outdoor room. Outdoor 

airflow rates were not measured for these 

units. Air is drawn in through all sides of the 

outdoor unit and discharged through the top 

of the unit. A sampler mounted around the 

outdoor coils measured dry-bulb temperature 

and relative humidity as it entered the 

condensers. 

The instrumentation for all tests is divided 

into air-side and refrigerant-side 

measurements. The air-side temperature 

measurements for both the inlet and outlet of 

the indoor coil unit are made using type-T 

thermocouple grids. A combination of dew 

point and relative humidity sensors were 

used for the inlet and outlet of indoor coil 

unit. For the outdoor unit, both temperature 

and humidity were measured on the inlet 

side of the condenser. Because the indoor 

enthalpy method was used for all tests, 

condenser outlet RH was not measured. Both 

inlet and outlet temperatures were be 

measured with type-T thermocouples. 

BILLING CODE 6450–01–P 

Refrigerant-side temperatures and 

pressures were measured throughout the 

system. Refrigerant-side test points are 

shown on Figure 2. With the exception of the 

refrigerant flow rate, the outdoor unit power, 

and the air flow differential pressure, the rest 

of the measurements are temperatures (drybulb, wet-bulb, dew point) and pressures. 

Refrigerant mass flow was measured with a 

Coriolis-type flow meter placed on the liquid 

line after the condensing section of the heat 

pump unit (Figure A.2) for both heat pumps 

units. Separate mass flow meters were used 

for each heat pump unit. 

The data acquisition system converted 

signals coming from all the sensors in the 

indoor and outdoor rooms into temperatures, 

pressures, flow rates, or power. A data logger 

was used to collect data from the testing 

apparatus. The logger is linked to a computer 

where the data was visually displayed during 

testing. Once a test was complete, the data 

was transferred to another computer for 

processing. Each channel was scanned by the 

logger at regular intervals and the data was 

stored every thirty seconds. A minimum of 

one hour of steady state data was collected 

as per the standard’s specifications for 

cooling and 30 minutes for heating. For 

cooling tests A and B, steady state was 

maintained for one hour before the start of 

data collection in order to ensure that steady 

state dehumidification had been achieved. A 

description of the data acquisition test points 

is listed in Table 1.

BILLING CODE 6450–01–C The test procedure consisted of setting up 

the CES unit as per manufacturer’s 

recommendations, charging the system(s), 

installing the appropriate instrumentation,

and running the selected tests. The tests 

conducted were selected by following the 

Standard, HRCU–A–CB. The Standard did 

not describe how to test a unit with eight 

indoor blowers, dual circuited evaporator 

coil and two heat pump units. Since the 

Standard did describe how to test a unit with 

two compressors which closely models the 

heat pumps, it was decided to follow the two 

compressor model of the Standard for all 

tests. Because of the way the CES proprietary 

control system operated the eight indoor 

blowers, it was decided to use 400 cfm per 

ton air flow for each compressor (2.5 ton heat 

pump). 

When test points were selected from the 

guidelines, tests were conducted at the 

appropriate indoor and outdoor temperatures 

for single heat pump operation and when 

both heat pump units were operating. There 

were three exceptions. When in cooling 

mode, Test C was conducted for full load 

operation only. When in heating mode the 

62F test was conducted with only single heat 

pump in operation while the 17F test was 

conducted for dual condenser operation only. 

The test point room conditions were as 

specified by the Standard 210/240 

guidelines. 

When cooling tests were conducted the 

moisture measurements were made using 

chilled mirror hygrometers in combination 

with relative humidity sensors as a backup. 

In addition to the two sensors, condensate 

was collected during all A and B tests. The 

energy balances were based on the amount of 

condensate collected. During the last few 

cooling tests, the hygrometer used to measure 

moisture at the evaporator exit failed. For 

these tests, the sensible capacity was 

calculated using the formula btuh = 

1.1*cfm*(Tair_entering¥Tair_exiting). The latent 

capacity was calculated from the measured 

condensate for all A and B tests. For heating 

tests, the chilled mirror hygrometers were 

replaced with relative humidity sensors. 

Results 

A summary of the results of the tests for 

the full load operation of the Cascade Energy 

Saver (two heat pumps and eight indoor 

blowers at a total of 2000 cfm) (hereinafter 

referred to as ‘‘Full Capacity’’) are included 

in Table 3 below. A detailed summary of 

each test is included in the pages that follow.
