2. Meeting Summary 

June 3, 2015

Exhaust fans Presentation by Henry (Skip) Ernst – Daikin 

Additional issues discussed:

- The metric needs to account for fans operating at low pressures.

- OEMs would be negatively impacted if a regulation led to having increased fan 

sizes.

Air Handlers: William Smiley – Smiley Engineering LLC 

Additional issues discussed:

- How does the WG wish to rate fans in air handlers?

o Two testing configurations were discussed: fan only (AMCA 210) and fan 

in a box (AHRI 430). The performance of the fan would be different 

depending on the testing configuration (impacts of cabinet and coils 

configurations)

o AHRI to provide a recommendation.

AHRI: Laura G. Petrillo-Groh Presentation - AHRI 

Additional issues discussed:

- Robert Whitwell expressed that if a fan in a covered equipment is already 

regulated as part of a metric for that covered equipment, he would like that fan to 

be exempted from the fan regulation. The example of condenser fans in 

commercial unitary air conditioners was provided. 
o Two situations were then discussed: (a) exemption of fans purchased by 

OEM equipment manufacturers and integrated in OEM equipment as well 

as exemption of fans integrated by the OEM manufacturer in its 

equipment; (b) exemption of fan integrated by OEM equipment 

manufacturers only. 

o The issue of being able to physically identify fans going into specific 

applications and covered/non covered equipment was also discussed. 

o DOE asked AHRI to provide a recommendation.

Cooling Towers: Larry Burdick – CTI/SPX 

Additional issues discussed:

- What are the physical features that differentiate cooling tower fans? (e.g. third 

party certification, large tip clearance)

Motors/Drives: Dan Delaney – NEMA/Regal Beloit 

Additional issues discussed:

- The WG will provide feedback on what the preferred approach for calculating 

default motor and control losses.

June 4, 2015

Definitions: Wade Smith – AMCA 

Additional issues discussed:

- AMCA recommends using a limit of 25kj/kg to differentiate between compressors 

and fans. 

- DOE will provide a summary of the edits to the definition for the equipment 

classes and will circulate to the WG 

NODA Analysis – DOE 

- Input lists for which WG members need to provide alternative input for sensitivity 

analyses: 

o MPC increase by EL for all fan equipment classes (NODA uses no 

increase for some equipment classes)

o Cost recovery period (NODA uses 30 years)

o Annual operating hours in commercial sector (NODA uses operating 

hours derived from Energy +)

o Load profile assumption for some fan selections expressed as a 

percentage of design flow and percentage of operating hours (NODA uses 

100% of annual operating hours at 100% design flow) 

o Lifetime (NODA uses a lifetime between 6 and 60 years)

Ratings and Representation – DOE 

Additional issues discussed:

- DOE will send a revised PowerPoint to the WG.
