would that principle still apply in the scenario of a window and wall being in the equation? I would imagine if that were true than more efficiency could be produced with a smaller fan inside ductwork vs a large unit which covers the entire cylinder size.
The fan sucks the air from all directions, except for the exhaust direction. If you place the fan next to the window, the sides will suck the air from the outside. And since this is where the outside air tries to get into the room, you’ll be exhausting fresh air non-stop. But if you move your fan a bit inside the room, the outside air will be able to get in and the fan will only suck the inside air.
