<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I believe the first 4 volumes are the “core” DOE2.2 volumes, and the other volumes have been appended over time as eQuest/DOE2 have developed in more recent
years. <i><u>I’m not clear on</u></i> whether these in sum are any more or less “complete” than past or present manuals for the underlying DOE2 simulation engine itself. I am pretty sure some parts of this are compiled by & for eQuest specifically (Volume
5: Compliance Analysis in particular jumps to mind).<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Arial","sans-serif"">Do you not have a copy of a DOE-2.2 or DOE-2.1E manual? That would make it hard to understand how DOE-2 works.<br>
DOE-2 has many performance curves, depending on the type of equipment. The EIR-FT curves are either bi-linear or bi-quadratic functions of the entering wetbulb and outdoor drybulb temperature. The EIR-FPLR curves can be linear, quadratic, or cubic functions
of the Part Load Ratio (PLR). <br>
<br>
By the way,what I said yesterday was in reference to packaged SYSTEMS. If your model contains a PLANT model with a Chiller, then<br>
the keywords for the chiller performance curves change somewhat.<br>

<p class="MsoNormal"><span style="font-size:10.5pt;font-family:"Arial","sans-serif"">DOE-2 modifies the COOL-EIR using several curves COOL-EIR-FT as a function of outdoor conditions and COOL-EIR-FPLR as a function of the Part Load Ratio. I suppose you could
set those to be constant. Another way would be to just take the Cooling Load from the SS-D report and divide that by your constant COP. But my question would be, why do you want to do that ?<br>
