I am looking to take a portable AC unit and hopefully run a tube through a wall in another room while still cooling the room the unit is located. I have searched to attachments that could help but have come up empty. Any help would be appreciated.

    In my experience with a portable A/C unit, the cooling power was so anemic that it couldn't even cool one room, let alone two. – Johnny Jun 1 '16 at 4:12

Any way of circulating the air between the rooms will help, although I doubt you will be able to achieve uniform temperatures. Put the AC in the room that is hotter (e.g. has more windows) and then do the best you can with a fan or two.

Also, make sure the AC is properly sized for the area you want to cool.
