What are you going to do about condensation in the atic?

You can't just exhaust house air into an attic in the winter. It will wreck you insulation, and eventually the roof.

The attic is poorly insulated, I doubt it would matter. frown.gif

Though I am interested, what ideas would you have? The data closet has zero airflow whatsoever, and we're going to be putting about 500w of equipment in there. It's a space smaller than the size of an average walk-in closet.

Our original idea was to drop an HVAC vent in there, but that's a problem in the Winter because there's no thermostat in there and another can not be easily run there. Therefore, that equipment would be getting hot air dumped on it in the Winter... frown.gif

With this idea, two of the fans would be controlled by a Ubiquiti Networks mFi temperature sensor. When it gets above 80 deg, two of the fans will kick on, pushing hot air into the attic and drawing in cool air from the hallway. During the winter, the process is reversed but with the other two fans pushing the opposite way, therefore drawing cold air out of the attic and into the data closet.

I should add, this is Florida. It's almost ALWAYS extremely humid in the attics. And everywhere. redface.gif

LOL! Florida!

I'm in Chicago and the weatherman is turning off all the outdoor temperature tonight - It's going to be zero degrees!

What you propose sounds great.
