[CQ-Contest] shack air flow?

[K1TTT]

Normally in m/m contests we end up with windows open and a big box fan
running to keep the temperature down in the shack.  I am looking for
something maybe a bit more elegant.  Has anyone used those small high
velocity ducts to either blow in air or as exhaust ducts?  I am thinking
that one in each corner sucking out the hot air may be best, then I could
blow it down into the crawl space or upstairs to reducing heating need
during cold weather contests.  This would have to go above a drop ceiling
and preferably not be very noisy.
