1-door room air-circulation

can you put holes in the walls? can it be permanent? do you pay for utilities?

it's a rental so no holes or anything permanent. I pay for electricity and gas

anyone know how many fans would be necessary to have the air circulate the room like this?

>>1001992
Only one door?

Fan blows cold air through the top of the door, the higher pressure cold air descends and pressure displaces the hotair either upward or out the bottom of the same door.

It's a bit like blowing a fan out one side of a window so you get fresh in through the other side

You could also blow the air out from the room and create slightly lower pressure in the room so new air cycles in. This is exactly how fan blowing out a window words. But I think that might be less efficient for cooling than just pumping cold air into the room.

wouldn't blowing cold air in through the bottom and blowing hot air out through the top make more sense? cold air wants to stay down and hot air wants to stay up - once the cold air in the room warms up it raises and gets blown out

You're going to want to use the fans to blow air out of the room. Cooler air will be sucked in. Perhaps another fan to mix the air inside the room but since you only have one big opening you want to get the hot air out and pushing it out is not as good and sucking it out.

If you can actively push cold air and pull hot air then that'd be fine.

But cold air is higher pressure, so you'll create high pressure along the floor of the room relative to the outside room, so it might seep back out (cold air won't go up). If you pump cold air into the top of the room cold air will want to fall while hot air will rise (or go out the door).
