Marina,

Get a mini split like Turtle said. I have seen the portable units like
MovinCool. They will cool one part of a room at the expense of another
part. All the electricity that goes into them comes out as heat. they
make a better dehumidifier than air conditioner. If you put the
exhaust hose in a window like the instructions say, you make up the
exhause air with outside air and the net effect is zero effect, except
your electric bill goes up.
