Window AC in transom window

del, I explained how to secure the panel to the frame in my previous post. If using Plexiglass, it can be done, but you need to know how to work with plexi to make it work (expensive option, compared to using wood). Using Plexi/Lexan, means more heat can enter the structure, compared to glass & wood.

Window AC in transom window

I mentioned already that the windows are all blacked out with reflective attic insulation material, it is like a cave:

The plexiglass broke recently and I currently have the unit venting out a peice of 1/2" plywood covering the entire transome window, and then all other windows are covered with reflective bubble insulation (like the kind for car windshields) Still sweaty hot after 3 days of non-stop full blast A/C running.

Window AC in transom window

To all the doubters, I am now enjoying 73 degrees in my apartment where it was 85 just about 1 hour ago. I've got an insulated plywood enclosure that seals the back half of the AC to the transom window. The 140lb 28,500 BTU AC unit and plywood enclosure are held up to the window which is 10 feet off the floor by scaffolding. A 10 gauge 50ft extension cord allows me to plug the unit into the 220v range outlet. The only part I'm not sure on yet is the drain. The AC unit is designed to blow the condensate water through the condenser coils and outside by scooping it up with the exhaust fan. I can't have it doing that so instead I drilled a hole and mounted a fitting to drain the unit into a floor drain in my apt. It hasn't been humid enough to really test out yet so I'm not sure how that is going to work. It ain't pretty, but at least the place is habitable now, and it falls within the rules of not having AC's hanging outside the windows.
