Forgive me for my poor paint skill:
I have this small room, one door, no windows, one skylight. I'm planning to buy a portable air conditioner and put the hot air pipe near the lower area of the skylight, pressed against the mosquito net. Note that air will still be able to pass through all the net, not only the part near the pipe.
Room is about 3x3m width, 2.5m height. Skylight is about 1x1m width, 2m height.
The plan is that hot air should be able to get outside because it leaves the pipe with a certain speed and also hot air should go up because that's what hot air does.
During the day, when the air conditioner will be on, all windows in the rest of the house will be closed, so air should have no reasons to enter from the skylight. But even if they were open, 90% of the time air flows from windows to the skylight.
My doubts are:
- Will hot air really go out?
- In the "all windows are closed" case, if air goes out, it must also get in somewhere... the rest of the house is like six times the size of the room and in the kitchen (the furthest room) there are two small holes in the wall (10cm radius) for security reason (in case of gas leaks).
EDIT: The air conditioner that I'm looking at doesn't have a second input pipe, so I guess it will pull air directly from the room, and the room will pull it from the skylight. Now... It might create an air flow like the one in the updated picture where most of the hot air still get's out, or just suck back the hot air inside... What's the most probable outcome? Even if I find one with the input pipe, it will be useless if I can't put them both outside AND far from each other right? If so, I guess I'm out of luck...
