Where to find: casement window fans, air pump

[Gary Fritz]

We've got casement windows in our house. I'd really like to be able to put
a fan into one or more of them, but it seems all fans are designed to fit
into standard "slider" windows. Any suggestions for ways to put a fan into
a casement window? The main one I'd like (it's a clerestory at the peak of
our roofline, would be great for exhausting hot summer air) has a screen
size of 25.5x55".

Also, a bit more oddball: I'd like to find an inexpensive and preferably
fairly quiet air pump capable of continuous-duty use, 50-100psi. Our
bedroom is on the 2nd floor and a long way from the AC. I'm toying with
the idea of a putting a vortex tube in there, and sending the hot air out
the window. And of course you could reverse it in the winter. A couple
thousand BTU/hr could help the bedroom temperature situation a lot. See
e.g. http://www.airtxinternational.com/catalog/vortex_tubes.php or
http://www.newmantools.com/vortex.htm. Kinda crazy, but I'm sure it would
work... *if* I can find an affordable air pump.

I suspect you'll find that this will be a very expensive to operate
A/C system. A couple thou. BYU/Hr seems to require in excess of 25 CFM
at 100 PSI. That takes a big compressor, which draws big power. A huge
amount more power than a 5000 BTU/Hr A/C.

I was afraid of that. I wasn't sure what size of compressor it would take.
I knew this wasn't a real efficient way to get A/C, but I thought a "spot
cooling" application like this might make sense.

Ohwell. Thanks anyway! Anybody got any ideas on the casement fans?

You could make a box out of plywood. Casement windows suck for this
sort of thing (I have them too) but your is big enough that it
shouldn't be too hard to fit a fan into it. Is it protected from the
weather when open? Mine aren't. :-(

As already pointed out; won't work. I put a 7.5kBTU "window" AC unit
through the wall below a casement window in our bedroom. The 25kBTU
AC in the living room takes care of the rest of the house, at least
as little as we need AC.

Ick. That would be ugly, and would block light from that window. Doubt I
could sell it with the wife. Yes, it's protected from the weather -- there
is a roof eave over the clerestories.

I'd like to have an option for spot AC up in the bedroom, but I don't plan
to blow a hole in the wall to do it. I guess there are AC units that are
designed for casement windows (but why not fans !?), but that's not a great
option either. Hm.

Make the box out of Plexiglass. ;-)

The fan isn't going to do much for the light either. T'ain't nothing
free.

Blowing a hole in the wall isn't all that difficult. Under the
window is a perfect place since there is no load; makes it a piece of
cake. The only small issue I had was rerouting a wire using that
space.

Yeah yeah, we had one in a house I used to live in, years ago.

I think it looks ugly what with the open window sticking out. And you
still have to close off that part of the window opening above the
unit, as the whole window is open, and the unit will be smaller in
height than the window. It looks better if you remove the operable
part of the window, but you still need to block off the opening.

A new wall sleeve just for the A/C is a much neater solution.

If you have screens on your casement windows and it depends on the casement window, but we put a window fan in with screen in place and hooked a bungee across latches on Windows. It works but not pretty.
