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.

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:

1) Is there any way to vary the inside film resistance e.g. on a schedule?

2) 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.

3) Can anyone think of a different approach to simulating this effect, other than manipulating the inside film resistance values?

Thanks, once again.
