1 Appliance Standards and Rulemaking Federal Advisory Committee

Commercial Package Air Conditioners and Commercial Warm Air Furnaces Working Group

Term Sheet

June 15 , 2015

Background

On April 1, 2015 , DOE issued a Notice of Intent t o Establish the Commercial Package Air

Conditioners and Commercial Warm Air Furnaces Working Group To Negotiate either a Notice of Proposed Rulemaking (NOPR) or Final Rule for Energy Conservation Standards for Commercial Package Air Conditioners and Commercial Warm Air Fu rnaces

. 80 FR 17363 . This working group is established under the Appliance Standards and Rulemaking Federal Advisory Committee (ASRAC) in accordance with the Federal Advisory Committee Act and the Negotiated Rulemaking Act. The purpose of the working group was to discuss and, if possible, reach consensus on a proposed or final rule for the energy efficiency of c ommercial p ackage a ir

c onditioners and heat pumps ( specifically, air

- cooled with rated cooling capacities greater than or equal to 65,000 Btu per ho ur and less than 760,000 Btu per hour split and package AC and HP) and c ommercial w arm a ir f urnaces , as authorized by the Energy Policy and Conservation Act (EPCA) of 1975, as amended. The scope of this term sheet does not include package

terminal air conditioners and heat pumps (PTAC/PTHP) , single package vertical units (SPVU)

, computer room air conditioners (CRAC) , or variable refrigerant flow (VRF) systems. The working group was to consist of representatives of parties having a defined stake in the o utcome of the proposed standards, and will consult as appropriate with a range of experts on technical

issues.

DOE received 1 7 nominations for membership. Ultimately, the working group consisted of 1 7 members, including one member from ASRAC and one DOE representative (see Appendix A). The working group met six times (five times in

- person and once by teleconference). The meetings were held on April 28, May 11

- 12

, May 20

- 21

, June 1

- 2

, June 9

- 10 , and June 15, 2015

. The working group successfully reached consensus on energy conservation standards for

c ommercial p ackage a ir c onditioners and c ommercial w arm a ir f urnaces . This document includes the working group’s recommendations to ASRAC on the energy conservation standards. The group also chose to provide test procedure and metric

- related recommendations to the

committee

.

manufactured on and after January 1, 2023 must have a thermal efficiency at the maximum rated capacity (rated maximum input) not less than 81 percent.2

 Oil

- fired Commercial Warm Air Furn aces. O il

Test Procedure

Recommendation #2

.

 A rulemaking to amend the test procedure for air

- cooled, commercial package air conditioners and heat pumps with rated cooling capacities greater than or equal to 65,000

Btu/h and less than 76 0,000 Btu/h

, shall be initiated no later than January 1, 2016. DOE shall issue a final rule for the amended test procedure no later than Ja nuary 1, 2019. The primary focus of the rulemaking will be to better represent the total fan energy use, including considering a) alternative external static pressures and b) operation for other than mechanical cooling and heating. The energy consumption from the supply air fan during hours of operation when it is used to provide ventilation air and the energy use with the supply fan operation when the unit is in heating mode shall be included in an energy efficiency metric as a result of this test proced ure modification. Working group members will support the use of this new test procedure and any resulting revised metric(s) in the ASHRAE 90.1 building

standards. However, the new test procedure and any resulting revised metric will not be used

for assess ing representations or compliance with the standards described in this term sheet.

Recommendation #3

.



###  The Commercial Package Air Conditioners and Commercial Warm Air Furnaces Working Group recommend s to the Fans and Blowers Working Group that s upply air fans and outdoor

coil fans (used for heat rejection from the unit’s refrigeration system during cooling mode)

which are embedded in air

- cooled, commercial air conditioners and heat pumps with rated cooling capacities greater than and equal to 65,000 Btu/h and less than 760,000 Btu/h not be

considered for test procedures

, certifications, or standards in the fans and blowers rulemaking. This recommendation is conditional on findi ng a way to implement the fans and

blowers regulation so that it does not create loopholes for fans or blowers that may be used as

stand

- alone equipment or embedded in other non

- covered equipment. A fan standard may

cover fans sold as stand

- alone products that are also embedded in equipment covered in this

term sheet.
