All right...we have a problem here. I work in an old catholic school bldg. There's no AC in my room and the wiring in here won't tolerate adding one in this room bc there are already 15 computers running all day and it would trip breakers on the regular. We are leaving the bldg on June 18, so there's no plan to re-wire.
Students have work to do and I'm in this furnace all day long...trying to think of workable solutions.
My classroom faces East/South East. We have 6 windows...all on the same wall. The ceilings are high. There's one exit door and the hall outside has some windows in it. I usually open the windows early and turn 2 double window fans on exhaust for the first half hour, trying to suck in some cool air from the hall and blow out the hot, stale air from the night before.
The room is a square. There are computers along the north wall (6) and along that east wall (4). The door is in the west wall, in a corner. I'm on the top floor, directly under evil flat roof (black tar).
I have 2 double window fans (they have intake/exhaust setting). I also have a very powerful fan that is like the ones you use to dry wet floors quickly. There's a small table fan also.
Where would you position the fans for maximum effect? Would you open any of the 4 unoccupied windows if it were cool outside? What about if it were really hot outside? Keeping the door open helps bc it creates cross ventilation. The small table top fan and the powerful floor drying fan are aimed upward and positioned well within the room, not near the windows. i want to keep the air moving and the students awake. Buying more fans isn't much of an option, if I do, then I need to keep it to a minimum. I can't position a fan near the door for safety reasons (drat) and there's no way to hang any safely.
Right now, at 7:20am, it's cool outside, so I've moved the non-window fans to draw a little more air from outside, but I know it's going to heat up in a bit. Any suggestions for workable solutions?
