So I live in a rented house, it's old, like 1860s. It's been retrofit with central air so in the summer it mostly stays cool, but my bedroom on the second floor accumulates heat like crazy. It has 2 big, South facing casement windows, so a normal window AC unit doesn't work. Is there anything I could do to help keep it cool? Everything I've seen online basically says get a freestanding AC unit and an adapter for casement windows, but the AC units are insanely expensive. Is there a good way to rig a box fan or something to cool it off? I'm considering a plywood sheet the size of the window with a cutout for a fan, but not sure if that would really work. The room has cold air output, it no return vents to pull the hot air

In the summer, all bottom-floor vents are supposed to be closed off (or just close off the entire trunk that feeds the downstairs vents directly.) This will send the cold air to the upper floors first.

A fan will simply pull the hot air out of your room, pulling cooler air from the rest of the house into it. It will work, but perhaps not that fast or that well.
