Friend of mine recently installed a little portable AC in his "man shack" out back. I don't know the exact model and size, but similar to this generally:
Guys RUN from these, here are the particulars. These types only have ONE hose, for exhausting condenser air. That air has to come from somplace.....and that is FROM the very room you are trying to cool.
This means that, meanwhile, the unit is sucking hot outside air BACK into the conditioned space through every crack in the building "it can get it's hands on."
Condenser air should be ALL outside, SEALED from the conditioned space.
Some of these units have TWO flex ducts.........condenser intake and condenser outlet. Those work fine, all else being "hunky"
THESE THINGS ARE JUNK and with all the gob't crowing about efficiency, they should be outlawed.
The efficiency on these things has GOT to be dismal. "In effect" you are trying to cool the building with a window open.
