earlier because I sensed that there was a way to show extra energy savings if
we could define the baseline, but I don’t think anyone in the community
has an answer. I am thinking that unless someone gets an official ruling
otherwise, I am going to assume the DX baseline is single stage for smaller DX
units, 2 stage for larger (above 10 tons?) DX units, and 4 stage for really
large (above 40 ton) DX units. It may not be right, but if people force you to
use things and not define them, you have to guess something.<o:p></o:p></span></font></p>

to pull out the fan energy and yes I am familair with the AHRI 340/360-2007
methodology for creating an IEER value, and yes I concede that modifying the
part load curve without modyfing the other curve is going to be an
approximation. The point is - given a baseline IEER value can
we create a baseline part load DX curve without the raw data? For that
matter, given a proposed system IEER can we create a part load curve?
I think the answer is, you can't. I can probably solve the proposed part load
problem by asking a manufacturer for their IEER data, but what to do about the
baseline?</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>On our projects where we take credit for part load efficiencies we use
addendum s to 90.1-2007. This adds in IEER values for units so you’re
comparing apples to apples. The only projects we have modeled this on have had
baseline systems that were 9.5 EER with an IEER of 9.6. With such a small
difference between EER and IEER, the 25%, 50% and 75% values aren’t that
important. 9.5 EER at full load and 9.6 at the other values will get you the
9.6 required for baseline. For information on how to make curves I would look
through the archives of this user group, there have been some great
explanations.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

to fit a particular DX cooling system? If so, when you compared it to a
baseline DX cooling system, did you use the original eQuest DX-Cool-EIR-fPLR? <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:

(which shows up in ASHRAE 90.1 -2010 Section 6) how are we going to modify the
eQuest DX-Cool-EIR-fPLR to accommodate the IEER? The IEER is a single number
and we have no idea what the 25%, 50%, 75% cooling load ratios look like.<o:p></o:p></span></font></p>
