Let me take a crack at this. If by design capacity you mean the chiller running at 100% load, you would create the curve(s) by normalizing around your ARI design conditions i.e. the PLR curve would be 1.0 at this point, call it ARI Cap and the other points would be 90% Cap/ARI Cap, 80% Cap/ARI Cap, etc. The same would go for your temp curves. If, however, your chiller is operating at 120%, or some such other level, I would normalize the curve around the ARI design conditions of the chiller at 120%. I had to do this for a VRV hp that was selected at the 120% design condition.<br>
<br>I find this from the DOE2 manual the most helpful:<br><br>

evaporator/condenser dT</span></u><span style="font-size: 12pt; font-family: "Times New Roman","serif";"> - The temperature differential between the
condenser and leaving chilled-water. The meaning of the condenser
temperature varies according to condenser type. </span></p>
<p class="MsoNormal" style="margin-left: 2.7pt;"><span style="font-size: 12pt; font-family: "Times New Roman","serif";">For
most chillers, the dT has a relatively small effect on part-load performance. However,
for variable-speed centrifugal chillers, the effect of dT is as important as
the PLR. This is because the pressure rise across the impeller is
proportional to the square of the impeller’s speed. Unless some form on
condenser temperature relief is employed to reduce the temperature (and
pressure) differential across the chiller at part load, the performance of a
variable-speed chiller may not be significantly different than that of a
constant-speed chiller.</span></p>
<p class="MsoNormal"><span style="font-size: 12pt; font-family: "Times New Roman","serif";">To model power
consumption as a function of the PLR only, use a CURVE-FIT of TYPE = QUADRATIC
or CUBIC. To model as a function of both PLR and dT, use a
BI-QUADRATIC-RATIO&DT curve. The curve must be normalized to 1.0 at full
load and the rated temperature differential. </span></p>
<p class="MsoNormal"><b><span style="font-size: 12pt; font-family: "Times New Roman","serif"; color: red;">Note that,
for centrifugal chillers, ‘full load’ is defined as the ‘maximum capacity’, not
the ‘design capacity’.</span></b><span style="font-size: 12pt; font-family: "Times New Roman","serif";"> Refer to the DESIGN-PLR keyword for more
information.</span></p>
