Internal window AC

[calumet]

I like the top cabinet installation that Craig developed for his CampInns as discussed in this thread:
http://tnttt.com/viewto ... nditioning
However, The exhaust/intake venting question was never answered.
Presently, I would have to go with john’s instalation as shown here:

Since these discussions, has anyone developed the approved solution for a top cabinet mount without a through the roof vent that addresses isolation and venting of exhaust/intake air and venting fresh to return? Or, have there been improvements on the floor mount? I read some discussions on floor mounted fresh air vents and some were going to try and incorporate them into the return air for the AC.

One of the drawbacks to the way I mounted my AC is that cold air does not rise. A pocket of hot air pooled in the top of the tear before I installed some small round vents up high to let the hot air "drain" out. A plus is that it is easier to mount the AC low than high.

2bits solved it another way in this thread: (look for the side view cut away showing the cold air routing from the AC) Takes up storage space, though.

I don't think the campinn has a problem with ventilation. A couple of 4" vents could help if there was a problem (one for intake and one for exhaust). Home Depot has them for around $30. Wire then so they come on with the AC or when the AC breaker is turned on.

Asianflava has a good high mount install that can be found here:

I don't think he has had any problems with his install.

I'm traveling right now, maybe I can post some pics later tonight. My blog is down and only shows the last entries. I haven't been updating it so the last entries are very old.

I sort of designed mine independently but after talking to Craig and Cary, it is very similar to how they do theirs.

Basically, it vents hot air up thru the top and draws cool air in from the galley.

Sorry asianflava

I guess I should have flipped through the pics before posting the link.

A great AC install, though.

Thanks, guys. Glad you both responded. Between y’all and 2bits, it looks like the solution has evolved.
The question on the CampInn I was referring to was from the link where a poster was asking about the isolation and Craig didn’t respond.
The only thing is, I definitely don’t want a duct to the top and really don’t want one on the sides if I can keep from it. I would much rather keep them on the underside if at all possible and will try to figure out how to take the great ideas you guys have developed and mod a little to vent/intake from underneath the TD.
Thanks again for the response and posting the ideas to help others.

I believe that if you vent them both down you have a chance of the "intake" portion sucking up dirt and trash.
The higher it is the cleaner it is.
Toyota forklifts have the right idea, they run the intake air from the top of the roll cage (I know, different... but yet the same)
