air conditiong rear of ac unit in galley or that pet cool

[dms2871]

hey every one been putting a lot of thought in this build comes down to this I want to build the Wyoming Woodie with air conditioning.
I have been looking on here and seen people put it in the galley holes cut in floor to vent. fronts and sides of trailers with these 2 round holes cut next to each other for the pet cool type air conditioner. and also a split system that the condenser sits on the front. and a window shaker with a box made to it that just goes to a window or side door window. what works best if in galley the lid has to stay open to vent anyway does everybody leave theirs open at night or close them. im not shure being people live and camp in different enviornments ie Bears what are some of
your inputs to this, im kinda pointing to the window shaker out side with a make shift boot to window with like dryer vent material

Well just watched a video on a guy who did this with no return and the window shaker isn't going to work on outside ducted to window

Mark came up with a good way to permanently mount a window a/c unit mounted in the galley area that works without having to open the hatch. Here's a link to that part of his build: http://www.littleswissteardrop.com/air.html

Keep in mind that the a/c does take up room. For this reason, and perhaps others, I believe that Mark's teardrop is 11 feet long (by 5 feet wide by 5 feet tall.)

There are several posters here who keep the AC unit on the outside and run tubing (in and out) to the trailer. I believe that is what you are referring to with the "dryer duct" reference. I am one, I believe Shadow Catcher is another and I remember photos of others doing it, but cannot recall their names. It does work as I have proved for my CT. And it takes no permanent space in the trailer other then hauling it around to remove once at the campsite.

I've done it too. I one mounted in the galley for a long time, then I discovered that I rarely camp where I really needed AC. Once every 10 trips or so. With the tubing system, I only bring it when the weather says I need it, and I can carry it in the TV. It only takes a few minutes to set up, and I think it works better with the tubing ( its definetly quieter)

The current plenum is cardboard with metal flanges from Home Depot. Originally I was going to have a sheetmetal one made, but now I'm leaning towards a canvas/Titebond 2 covering.

I mounted mine on a slide in the front and slide it 'out' when in use and back into the unit when traveling.

Tom, I also did a cardboard one, but mine was a test to see if it worked. Then I made one out of plywood as a more sturdy setup with the intention of having a sheet metal one made up. But I would like to first see how your make yours out of canvas. Are you still going with cardboard or maybe a plywood?

This location was only to test concept. It worked and I added the permanent tubes thru the bottom of the CT galley area up to the false wall. This mockup is too big and the final one will be slimmer.

My cardboard box was also to test the concept, but I ended up using it on a coupole of trips and its held up pretty well. I'm considering remaking part or all of the plenum with luan. I"m in the middle of a project to replace the luan roof, and skinning it with fabric/TB2/Exterior paint. Once I finish that I will apply what I've learned to this project.
FYI, I made my vents come out the side of the unit instead of the face. This was based on pictures I saw of the petcool setup. My theory is that the system would be less likely to ice up in high humidty under a cross flow setup.

Interesting. Hopefully you will make your new unit before my gives out so I can see if your ideas will apply to mine.
Since the AC unit has the outgoing vents on top going across the unit and the incoming vents (heated air) across the bottom, I wonder how complicated it would be to make the internal separators for side mounts.

BTW, my corrugated box board gave out at the end of the test. I think it was because of all the moisture that was in it.

Ours works well and I wrote up the learning process http://tnttt.com/viewtopic.php?f=30&t=44561

yeah I came across his build I just didn't know how well it performed, I do like your build though I was planning on building the Wyoming Woodie
I like your design but cant figure out how to draw it I have that scketch up thing but im used to reading hvac prints. im thinking of going to a split system since I work for an hvac company not shure how it would work.

is there anywhere I can find or get your type of profile? im getting a 5x8 trailer the one that northern tool sells

I just don't see how it works efficient enough that way. you would need at least 2 runs 1 for supply and 1 for return I don't see how it would work being that close together seems it would pull the air right back out being that close

what about rain on it I know the back is ok like if were to stick out of a window it would have to be water tight

thought about that too I didn't want to cut a hole in there

yeah I see that you said it had sweated I think both lines need to be wrapped in insulation cause where its at it isn't in a conditioned space
as far as it keeping up I think it needs more return air and its going to run hard and heat up. if there was a way to build a small economizer on these it be great. almost like a roof top unit but dinky

I still think this idea chokes the ac down on return and supply 4" -5" isn't big enough 4"=40cfm and 5"=60 cfm
im thinking more like 6"=100 cfm and an 7"=150 cfm not shure how much cfm these little units blow but it has to be atleast more than 40cfm and 50cfm and return the bigger the better but not that close together
