Default no wind




It seems to me that when one decides how and where to place exhaust outlets
for fume hoods outside the building, one makes certain assumptions about
how efficiently the waste air will be carried away, e.g. so that it doesn't
wind up in the air supply intake for the building.

Does it ever happen that a laboratory building or chemical plant has to
stop operating temporarily because there is so little wind that those
assumptions don't hold?

Apart from that, I'm interested in knowing where I can read details about
something called "wake analysis", which one apparently needs in order
to figure out where to place air supply intake and waste air outlets
so that the bad air doesn't get back inside the chem lab. Anyone know
where that is explained with lots of technical details?

Ignorantly,
Allan Adler

I have never once worked in a building where the fume hood exhausts
were not immediately upwind of the fresh air intake. It's some kind of
perversion of architects.

Right now, my lab will smell of ether one day, bacterial growth medium
the next, and something the next that smells suspiciously liike NO2.

In general the designers locate exhaust and intakes at different
levels so that mixing is avoided. There are Code mandated separations
as well.
