<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">I needed to use the existing district plant method for a local utility rebate recently, and by inspecting the PS-H report for my ¡°chiller,¡± which represented
the plant, I found that I was not getting constant EIRs after creating my own curves, etc. It was also not a constant error, getting worse in the cooler months and closer to my expected value in the summer.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">The fix was to remove any peripherals or vampire loads from the chiller power in the chiller properties dialog. I modeled the plant as a single, air-cooled
chiller, set my calculated EIR, applied the flat curves (as noted by others below), allowed the ¡°Min Ratio¡± to go down to 0.01, set ¡°Elec to Condenser¡± to zero (assuming that is already calculated in my overall EIR), and set ¡°Start-up Time¡± and ¡°Standby Time¡±
to zero, since in reality the water is available when the building needs it and we¡¯re not firing up a chiller just for me.<o:p></o:p></span></p>

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" style="margin-bottom:12.0pt"><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>
