Hiya folks,
I know that this is a bit off topic, but are there any ventilation
experts out there?

If I explain why I ask:
My employers stopped smoking on the premises a while ago, but knocked up
a partitioned room in the canteen
for the die hard smokers to use (rather that than lose them).
However the canteen quickly fills with smoke, making it unbearable to
non smokers.

The canteen is approx. 70' long X 20' wide X 10' high, ate each end is a
16" (approx.) fan.
The partitioned smoker room is an enclosed room with a small 9" fan in
it
(its all that would fit in the roofspace available as its next to some
windows).

What happens is that "the smokers" come and have a smoke, filling the
room and the smoke just happens to
leach out as the fan in there is inadequate to extract it.
The fans at either end keep getting messed with as everyone seems to
have their own opinion as to how best to operate them.
So when it comes time for me to go and eat my dinner, the air is stale &
bad to breath, I then have to open the windows & everyone complains of
getting cold etc.

If there is an expert out there could I beg a suggestion as to the best
way to operate the fans?
(I know the "best" thing is to get rid of the smoke room, but that's not
going to happen for a long while).


Here is a rough ASCII drawing of the room.
