I have a shed with extremely small windows that I use mostly for
storage, but I do have a small area with a work-bench, etc. I also
have a window-mount air-conditioner that I received from a friend
basically free (on a trade). The unit is probably old, but my friend
said it hadn't been used much. This is not an evaporative cooler, by
the way. It's a regular, 220-Volt air conditioner.

Why not just cut a window for the unit?
