Curved Duct For Heater/AC Unit

Post by apk » Wed Jul 27, 2016 11:23 pm

I have three "through wall" heater/AC units in my apartment... I've always thought that they'd be more efficient if the top-facing output duct was redirected towards the middle of the controlled space instead of venting straight up. So I thought I'd try to design and print a deflector that fit on top of the units. In the interest of saving time and material, the curved duct matches every other lateral grate divider, and the total deflection is 30 degrees. It's the largest piece I've printed so far (in terms of material and print time: 254 grams / 11 hours 54 minutes).

The ducts are symmetric except for the locating tabs... which are printed on top but are installed facing downward.

Saw something similar on Amazon the other day...

Might be worth sticking a fan on if you want to go the whole hog, seems to be make a lot of difference.

Ah, interesting solution for an old-school radiator. My Heater/AC has a built-in fan; it just didn't have any way to direct the flow of air.
