To cool off our house with a fan at a door or window, do you push air out or pull air in?

Question

Assume it is cooler outside than inside. We ususally use the fan at night to cool off the house. We use the fan in two places: either in the hallway outside the bedroom ,,,, or ,,,, in the doorway where we go out to the deck. So there might be two different answers????? Hope this helps.

Answer 1

depends on your set up

if you can set the fan in a window so that there isn't a lot of extra air space around it, and if you can open a window on the other side of the room or house, then the blow out works great

if you have a big door and a small fan, the blow out method tends to take air from very near by, including the outside and blow it back ouside

if you cant open another window or door strategically go get cross flow then blowing out won't help at all

if you can get near the fan, and you can't set up for good blow-out flow, then you need to blow in from the door or window and get as close as you can to the fan

Answer 2

Always blow the fan in to the house. Unless the fan is in the roof. Cool air is heaver than hot air so it goes down an the hot air goes up. So a roof fan you needs to blow out or up so it will pull the hot air out while sucking cool air in the windows which will go down to the floor and build up till the cool air fills the room or house. Then the warmer of the cool air will start over flowing and going out. Just like water does.

Answer 3

If the whole house is hot and it's cooler outside - I'd pull the air in.

Our downstairs is cooler as the warmer air rises so, if it's "reasonable" outside, I'll place a fan upstairs pushing air out.
That seems to draw the cooler air upstairs.

Don't know if that's right but that's what I do.

Answer 4

Using an exhaust fan, in a window or at a door, you will want to draw air out of the room; therefore the fan will be blowing into the room. It circulates the air then and exhausts it as the air moves from the fan around the room and back.

Answer 5

the actual incontrovertible fact that there is in elementary terms one AC unit working in between the bedrooms, the situation of the fan dealing with the two way will maximum not fairly do lots in terms of cooling something of the domicile. it may particularly help, however the undertaking is that the AC unit can in elementary terms cool lots air at a given time, jointly as something of house is being warmed via the exterior environment. once you place a fan on the door of the mattress room with the AC unit, the fan can help redistribute the air between the cool air in the mattress room and something of the domicile. it is not significant which way it faces as a results of fact jointly because it strikes air from the interior to the exterior, there'll be air compelled to pass from the exterior to the interior. The mattress room will carry in elementary terms lots air.

Answer 6
