Here how to build a ghetto mini split.
Get a box-to-hose reducer from Lowes/home depot.
Tape it on top of a square unit,yes the half in gap is needed...use HVAC tape.its aluminum and made for this application.
Run hose from reducer to room,and add a booster inline fan half way..
Now,you need a remote switch cord.this is a cord that plugs into a circuit,but has a switch and ANOTHER cord attached to the switch,and its run to whatever activates the power(your cap controller) this isn't completely necessary,but is if you're running more than 1200w on the same circuit with ONE switch on the circuit..too much,you'll fry your controller.
Plug your a.c. and booster fan into the remote switch cord,plug switch into controller..
Run hose from a.c. into your room..and your done.
Leave your controller in the area it should reign over,and set it to what you want,the a.c. should be on max cool and fan always,its no longer controlled by anything but its temp sensor,so it needs to stay on low. outside that area the a.c. unit sets,cooling that(unscented) air and blowing out that unsc
ented exhaust,while pumping cool air into another room.
