i actually own this....
and it would work to cool yourself in a bed, in a chair, or like personal space in a tent.
it does have a 2 hose duct system for venting hot air.
it does work very well to dehumidify, and my plan was to wire this up to 400+ watts of bed mounted solar to run a fridge and this AC. I work out of my truck in the hot florida sun. i hate idling the PW so i use this to take the edge off.
it runs at 250 watts and i could keep this running anytime the sun is up.
if i could create a curtain for the front half of my truck cab(or contain your sleeping space/lounge area, and use window shades) it will keep you comfortable.
not cold. just comfortable.
i would probably look at Rigid Mini DC system, or DIY 5kBTU window shaker with ductwork.
