<br />M1508.3 Intermittently Operating Ventilation Systems.
<br />The delivered ventilation rate for intermittently operating
<br />ventilation systems shall be the combination of its delivered
<br />capacity from Table M1508.2, and its ventilation effectiveness
<br />and daily fractional operation time from Table M1508.3.
<br />Qf = Qr / W)
<br />Where:
<br />Qf = Outdoor air flow rate
<br />Qy = Ventilation air requirement (from Table Id 1508.2)
<br />c = Ventilation effectiveness (from Table M1508.3)
<br />f = Fractional operation time (from Table M1508.3)
