<p class="MsoNormal">So… funny story?<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I’ve <i><u>approximated </u></i>radiant cooling and radiant heating slabs with a variety of approaches (EDR being one such helpful resource – more advice is contained in the archives for these mailing lists)… but I more recently stumbled
into a very simple, not-so-well documented system type that has been around for a while but never caught my eye during a project in development. I would give this a try next time I’m in your situation involving radiant heating only:<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal" style="text-indent:.5in"><u>Volume 3: Topics<span class="d2hbreadcrumbslinkseparator"> >
</span>Air-side System Types<span class="d2hbreadcrumbslinkseparator"> > </span>SYSTEM Type = FPH<o:p></o:p></u></p>
<p class="MsoNormal"><img border="0" width="741" height="701" style="width:7.7187in;height:7.302in" id="Picture_x0020_4" src="cid:image003.png@01D244AA.AEECCF90"><o:p></o:p></p>
<p class="MsoNormal">See also: <u>Volume 2: Dictionary<span class="d2hbreadcrumbslinkseparator"> >
</span>HVAC Components<span class="d2hbreadcrumbslinkseparator"> > </span>ZONE<span class="d2hbreadcrumbslinkseparator"> >
</span>Heating Equipment / Sizing<span class="d2hbreadcrumbslinkseparator"> > </span>
Floor Panel Systems</u> for a zonal input of interest.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">This is accessible in the detailed interface at the airside dropdown as System Type: “Radiant Slab.”<o:p></o:p></p>
<p class="MsoNormal" style="text-indent:.5in"><img border="0" width="337" height="520" style="width:3.5104in;height:5.4166in" id="_x0000_i1026" src="cid:image004.png@01D244AA.AEECCF90"><o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Not to get anyone’s hopes *<b>too</b>* high up: this appears specifically designed to tackle radiant
<u>heating only</u>, but this option could certainly have saved me some efforts in the past where I was unnecessarily “dummying down” more complex system types to match reality.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Highlighting: FPH has zero capacity to deal with mechanically driven outside-air ventilation (or general air circulation)… No fan system power inputs anywhere. If ventilation is driven in via the likes of zonal restroom exhaust however,
this might be the perfect system for your explicit modeling needs!<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Also for a multi-zonal system as illustrated (primary/secondary pumping), I’d want to further explore whether it’s necessary to define a ton of secondary pumps/loops on the hydronic side (assigning unique loop/pump pairs to individual zones),
or else to what extent those secondary zonal pumping energies are automatically modeled without further system/zonal inputs (I’m not aware if they exist)... the doe2 reference manual entry is a little vague on this front.<o:p></o:p></p>
