<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">More recent versions (2016) of the ACM include some updated curves for chiller performance, DX performance and VSD fan part load performance. Sometimes with
sources for the new items. The coefficients are even helpfully listed in a companion spreadsheet, available at
<a href="http://www.energy.ca.gov/title24/2016standards/ACM_Supporting_Content/">
http://www.energy.ca.gov/title24/2016standards/ACM_Supporting_Content/</a>. Where applicable, coefficients are provided for both eQ and E+ correlations.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">For water-cooled chillers, there are path A and path B chiller curve sets by capacity/type. Path B is for chillers with better part load performance, that is
with lower IPLV/ARI-design kW/ton ratios. The target ratings are listed in the tab Chiller Curves – Ref Only. I think one can get reasonably close to actual performance by picking curve sets where that ratio is as close as possible to that ratio for the chiller
(real or baseline requirement), you want to represent. Note you can take any set of chiller curves, and evaluate them in a spreadsheet at the IPLV conditions, and weight the resulting ratios to get the simulated IPLV. There is no definitive or “recognized,”
way to go the other way, though there really should be some spreadsheet from some authority that takes chiller type, # of compressors, IPLV (or performance at the 4 points), ARI rating, and spits out
<i>reasonable</i> curves. <o:p></o:p></span></p>

<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">For air-cooled chillers, the ACM has just a few very similar sets of curves. None appear to represent current advanced A-C chillers with much better low temp/low
load performance now available. Also note that the eQ chiller “Min Cond Temp” should be adjusted down to 50F or so to represent modern A-C chillers. But AC chillers are never in a PRM “baseline” model anyway, if that is the issue.<o:p></o:p></span></p>

ASHRAE standard or a manufacturer publishes those part load factors, you still are going to have conditions in reality (and your simulations) where it isn’t always 65 degrees outside while you’re 50% loaded (for example)… the major message/takeaway here is
that IPLV was made to marry manufacturers and laboratory conditions, to the general benefit of specifiers and prescriptive standards, not for us in the simulation world.

chiller. Custom hourly reports alongside a weather file coving the full range of AHRI conditions to “backtrack” the effective IPLV of a simulated chiller to see how closely the selected library or your own custom curves come to replicating the IPLV prescribed/tested.
If I had such a “test bed” model on-hand I’d share it with the community here, but I haven’t invested time to pursue that concept to completion yet.<o:p></o:p></span></p>

came with v3.65 b7163 anyway)… they might match exactly elsewhere… has anyone done the legwork to assess what equipment/research was used to develop those curves in relation to the eQUEST curve library? They might be generally preferable as a default if they’re
built from trustable and better/more current sources, and if so I’d be inclined to transpose into a custom library file (and possibly share with the community thereafter)…<o:p></o:p></span></p>
