<p class="MsoNormal"><span style="mso-fareast-language:JA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:JA">So… a solar-powered refrigerant compressor?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:JA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:JA">I suppose you could model a small PV array to generate an appropriate kW output profile within eQuest, then just dump that into the building meter with a normal DX-system. You’ll want that airside
system to have some deliberately-assigned availability scheduling so that it cannot actively cool when there is insufficient daylight… but otherwise I think you’d define that system normally. The biggest potential hurdle with that approach might be extrapolating
the actual efficiency/performance of the equipment (sans solar contributions) from the manufacturer.
<o:p></o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:JA"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="mso-fareast-language:JA">I might sooner use a 3<sup>rd</sup> party software, purpose built for estimating PV system performance, over eQuest though... eQuest is capable but frankly a bit unwieldy for average joes like me, lacking
specialized and deep knowledge of PV technology. I would avoid it through post-processing if possible, but if you do go a 3<sup>rd</sup> party PV analysis route and you MUST get that generation into your eQuest model, you can use the library entries for a
PV generator alongside an electric sale meter to “back in” a generation profile aligning with your outside analysis.<o:p></o:p></span></p>
