Cooling question

I have a tent with an air cooled hood. I just bought a portable A/C with the duct work that comes out the back to vent through the window. Could I hook up my tent exhaust to the A/C's exhaust via a splitter and vent them both out the same window to make it look less suspicious.

Here is an example of what I would do, let me know if you see any flaws with it.

The 4 inch duct is kind of necessary as I only have like 4.5 in of clearance between tent and roof of room.

Can you put a splitter in the tent and run 2 seperate - 4 inch exhaust?

yes it will work.. the a/c alone will push its own air thru the duct..only one issue is when the a/c is off will the air from the tent push thru the a/c instead of going out the window?? might want to look into a flap to stop back flow..

I'm think about doing something along the same lines and I found this, looks to me like it should do the trick http://www.amazon.com/Fantech-RSK-Backdraft-Damper-Duct/dp/B000VMHYH4 . You can probably find one at your local hardware store.
