Air Supply A/C

[Tombstonebilly]

I am thinking about putting a 5000 btu A/C on the front wall and redirect the air flow with ducts, should I put the cold air ducts near the roof or down near the floor ? I plan on having warm air ducts(intake) about half way up the front wall on each side.I plan to use the switches and controls off a/c in a different place so you cant see the ac unit

I would say, put the cold air ducts up high to cool the hot air in the cabin. It will also keep it from blowing on you.
Here is how I did mine. I haven't used it on a 100+ day yet, but if I don't like it there, I will add ducts to bring it out farther and blow upward.

For now mine is on the floor blowing up. Bought it specifically because it blew up. As for ducting, " air return" should probably be on a separate side. Td's aren't very big and cool/heat easily with enough ventilation

Edited cause I thought about it some more. There really isn't a lot of room for up and down in front with a regular tear.

Hi,

Air conditioning vents/outlets should always go up high if possible, since cold air falls.
Cold air return should be down low, though in the small space of a tear, you can easily let the return air cycle through the front of the unit as designed, and just duct the cold air.

Here is a shot of my ducted 5000 Btu a/c, the round vent is the cold air, which blows through the adjustable angle vent over the bed.
The return air simply is pulled in through the unit which is near the floor.

Hey Rob. I saw the pic of your unit . I mean your AC unit. But I did not see any ducts attached to it. What's the deal? It looks like a nice install. I just could figure out how you got the cold air to the vents.

Hi Dooner,

I'm not sure I understand the question, but here goes...

The picture you saw was probably before I added the ducting.

The unit sits very low, and didn't cool the trailer very well.
It was great for cooling your feet...
I built a metal box that fits over the front of the unit and used flexible insulated duct hose from there to the vents.

The return portion of the unit was left uncovered.

Finding a place to run the duct up the wall was a challenge...
But it finally came to me! Build another wall!
The duct runs through a chase under the bed, then up the wall.
I used a piece of 1/2" ply in the corner of the room, at a 45 degree angle.
There is just enough room for the duct in the corner.

Thanks Rob.
When I looked through your album, I saw the AC without ducts attached to it. I thought I might have missed something.
That is a very cool (no pun) install. What or where are the vents from? If I get to use mine in 100+ heat and don't think it works as is, I want to add ducts to mine to blow up higher. Those vents look cool. I'd like to get some if I need them.
