<p class="MsoNormal">Good day everyone,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-CA">I’ve been looking at the new VRF capacities of DOE 2.3 and tried coming up with custom VRF curves to match the specifications of my VRF units but I’m having some problems.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">DOE 2.3 curves are function of saturated suction temp (SST) and saturated discharge temp (SDT) – However the specifications I have are functions of Outdoor DB and Indoor WB, and I’m not exactly sure how to translate these
DB / WB temps into SST / SDT. Seems to me I’m missing something here.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">I’ve looked at the guide made by </span><span lang="EN-US">Florida Solar Energy Center – it seems fine for EnergyPlus since its curves uses
</span><span lang="EN-CA">Outdoor DB and Indoor WB. But it doesn’t gives any insight on DOE 2.3 (or at least I didn’t catch any).<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><a href="http://publications.energyresearch.ucf.edu/wp-content/uploads/2018/06/FSEC-CR-1910-12.pdf">http://publications.energyresearch.ucf.edu/wp-content/uploads/2018/06/FSEC-CR-1910-12.pdf</a><o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I’ve also looked at Maddox’s presentation on VRF – There’s a slide that says that E+ and DOE 2.3 curves uses the same parameters and are interchangeable but I don’t really understand the “how” of it.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">So general question goes as follows:<o:p></o:p></span></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><![if !supportLists]><span lang="EN-US"><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]><span lang="EN-US">Did anyone have success in creating custom VRF curves for DOE 2.3? If so, would you be so kind as to share the method?<o:p></o:p></span></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo2"><![if !supportLists]><span lang="EN-US"><span style="mso-list:Ignore">-<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]><span lang="EN-US">If not, does everyone simply uses the library curves, whatever the VRF model may be?<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-CA">Thanks in advance for the insights,<o:p></o:p></span></p>
