What are good ways to increase air flow in a home with few windows and oriented unfavorably to the local wind direction (cheaply)? (lemmy.ml)

I've been racking my brain lately thinking of what are good methods to increase internal airflow in a house with few windows, all facing the wrong direction to catch wind. What are your ideas?

Edit: Breaking a wall to make more windows isn't an option.

I do this all the time, just stick 2 fans in windows on opposite sides of the house, 1 facing in, 1 facing out. Bam; cross ventilation!

Bonus tip: set them a couple feet away from the window frame so that you create a venturi effect and move a ton more air.

I would have thought putting the fans tight in the window would move the most air. Can you tell me more about this Venturi magic?

If you put the fan right in the window, it'll suck the air right back inside around the fan. If you put it farther away the air stream has distance to widen and pull in more air. That way you can get the air stream to "cover" the whole window, Not allowing any to flow back in through that window.

I stole this from someone in a different comment: https://youtu.be/1L2ef1CP-yw?si=aLTlAMKv_3p3ri2q

It doesn't answer your question, but it demonstrates his answer.

I have square fans that I sit directly on the window cill.

You'll probably still get more air moved if they're sitting back on a stool or table, unfortunately

Meh, it's good enough without being inconvenient.
