<p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1F497D">If your HRV is 80% efficient, and handles, say 100m3/h, then set your ventilation rate at 20m3/h (as this is all that you require to heat, the balance being
recovered by the HRV). You may have infiltration as well, as in your base case, to include. This avoids all that pesky plant simulation.<o:p></o:p></span></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">Hi,<o:p></o:p></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I'm looking for information on how to simulate HRVs in ESP-r.
<br>
<br>
I've got a house modelled, and I've run simulations to see what the loads are. I'd like to see how adding an HRV affects the loads on the house.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I can't find any specific information about how to go about doing this though. Can I add in an HRV somehow to a model with an idealized plant, similar to the hybrid mechanical/natural ventilation example in
ESP-r? That example has the plants to provide mechanical ventilation to the zones set up as separate zones and then I believe there's an airflow network set up between the different zones, but I think I'm missing some files.<o:p></o:p></p>
