The interior of your house is hot, the exterior cool. What would the most efficient orientation be for a box fan? Pushing hot air out of a window or pulling cool air in through it? (Solved)* - eviltoast

Secondarily, should the fan be outside or inside the window?

Asking for a friend. (Me, help. I can’t remember physics, it’s too goddamn hot)

Edit: I’ve opened all the windows and set up a fan a short distance from the window pointing out and it’s reduced the temperature to near-tolerable levels. Unfortunately, venting through the attic was a no-go but moving things aside might make it an option next time. Thank you all, I appreciate the help!

    Can you explain that? With one fan pushing air in, and one fan pushing air out, you should be achieving higher airflow than you would with a single fan pushing air either in or out. Especially if you only have the one window open. I know that when I open windows on both sides of my house, I get better airflow than if I have windows on only one side open.
