[sdiy] soldering with air conditioner?

[Amos]

seems like a ducted solder fan in conjunction with the AC might be the
most efficient.
you could make a little hood for your bench (it could be anything,
even cardboard taped together) or simply a length of flexible dryer
tubing to your workbench where you solder... put a nice little fan or
blower at the far end of the tube, which exhausts through an
otherwise-sealed gap in your window next to the AC.  That way the seal
for the AC is preserved, except for a conduit which draws air from
your soldering station and exhausts it outside.  There are many
squirrel-cage blowers which would do well for this, or look into the
kind of fan which is used for architecturally-installed bathroom
exhaust (sometime known as a "fart-sucker" fan).  You can pay a lot
for these new, but they come up constantly as surplus & salvage.

Cheers,

Amos
