<p class=MsoNormal>Another question related to my thermal mass passive cooling
project: Part of this project is to use ceiling fans for comfort cooling
during the day. We also are considering using the ceiling fans (under EMS
control) to run at night to improve the efficiency of the heat transfer to
walls during the precooling phase.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>It seems like the easiest way to simulate this would be to
adjust the inside film resistance downward during the times the ceiling fans
are running. To wit:<o:p></o:p></p>

style='mso-list:Ignore'>1)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Is there any way to vary the inside film resistance
e.g. on a schedule?<o:p></o:p></p>

style='mso-list:Ignore'>2)<span style='font:7.0pt "Times New Roman"'>
</span></span><![endif]>Does anyone have a sense of the relationship between
inside film resistance and air velocity, to establish a good value for the
times that the fans are running? We’re expecting air velocities of
~100-200 FPM near the walls.<o:p></o:p></p>

</span></span><![endif]>Can anyone think of a different approach to simulating
this effect, other than manipulating the inside film resistance values?<o:p></o:p></p>
