<p class="MsoNormal">I am running a model for an operating room. My goal is to show the system savings for a night set back. I am using a VAV system that is currently running 24/7 at 100% flow. My goal is to show the benefit of running this system at different
maximum airflow levels while maintaining constant flow during unoccupied times.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If my OR schedule is 5am to 5pm, I would like the fan to run at 20 ACH during occupied time, 10 ACH during the first 3 hours of unoccupied time, and 6 ACH for the remaining unoccupied time.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Can I achieve this by adjusting fan schedules, or fan parameters for different occupancy settings? Any advice that may point me in the right direction would be helpful.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">If three different levels of fan speed are too much to ask, I would be happy with being able to run at 20 ACH during occ. And 6 ACH during unocc.<o:p></o:p></p>
