<p class="MsoNormal"><span style="color:#1F497D">Julien,<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">You need to look at the rest of Table 6.5.3.1.1.A to do the calculation.<o:p></o:p></span></p>
<p class="MsoNormal"><i><span style="color:#1F497D">A </span></i><span style="color:#1F497D">= sum of (<i>PD x CFM<sub>D</sub></i>/4131)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">You do the calculation for each applicable device listed in Table 6.5.3.1.1.B. (As Cory mentioned, you only include the ERV adjustment if the baseline is required to have an ERV.)<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">For your ERV only, you have ((2.2 x 0.6) – 0.5) x (10,000 x 0.2)/4131 = 0.397 for each airstream, or 0.794 total.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">With no other pressure drop adjustments, A = 0.794.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">You then calculate total baseline fan power individually for each system, = CFM<sub>S</sub> x 0.00094 + A (for constant volume), using the baseline system supply CFM.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">If, for example, the baseline system with energy recovery has 12,000 cfm supply airflow rate, bhp = (12,000 x 0.00094) + 0.794 = 12.074 bhp.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Then <i>P<sub>fan</sub> </i>= bhp x 746 / Fan Motor Efficiency, using Table 10.8 for motor efficiency.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">You have to split the value for
<i>P<sub>fan</sub> </i>between the supply, return, exhaust and relief fans in the baseline in the same proportion as the proposed design.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">Hopefully I did that right and didn’t forget anything too important.<o:p></o:p></span></p>
