I read last night that somebody who lives in a country where it can be as high as 40 degrees, if their air con breaks they freeze a towel in the freezer, and then hang it in an open window where a through draft will help towards cooling the room.
I can remember an experiment with a fan and blocks of ice during the Victorian era being talked about on TV, and they did something similar where they cooled down the temperature of a certain part of a room by blowing the fan at the blocks of ice.
