Tiny air conditioners

As summer rears it's hot and humid head here in the deep south, once again, my thoughts turn toward some sort of air conditioning for my Lite*House. I've thought of a few ideas including replacing the front "emergency escape" window with plywood and a small window unit or cutting a hole in the wall below that window and hanging one there.

I don't like the idea of losing that light and the smallest window AC I can find is about 5000 btu; overkill for my tiny trailer.

Some folks have suggested "swamp" coolers but I don't think they would work too well in the humid south.

I've found units as small as 1000 btu that are made for telecommunication equipment racks but they are designed for indoor use and mount opposite of what I'm looking for.

Recently, I came across this little unit in a big box catalog: Shop for American Comfort Worldwide 1,000 BTU Personal Air Conditioner - ACW100 at The Home Depot. I'm thinking that it might be possible to mount one of these in the space where my icebox currently sits. Of course, I'd have to add an exterior vent and perhaps a fan, but it looks like it might work.

Any thoughts, suggestions or reality checks?

I had one of these and it worked nice when it was too hot for a fan.

Wolf and Martha have a small regular AC mounted in the front of their Little Joe where your spare tire is. They say it works great. It has a vinyl cover on it for traveling and they report no problems with leaks.

This should be a fun project and I could see it working to keep things cooler. Maybe not in the desert, but other places.

That's where the Lite*House factory put it, and that's where the Little Joe factory puts it... below the front window but above the mattress/seat cushions. Don't put it on the floor UNDER the bed, you won't get good air flow down there.

Here's an idea if you only need A/C occasionally. Over on the teardrop forum, some folks carry a window unit separately from the trailer. In use, the unit sits on the ground with a special-built plenum on the front to adapt the cold air outlet to a dryer hose. The hose carries the cold air into the trailer. A window unit with a remote control would be perfect.

Davie, I think 1000 BTU would be too small for a trailer, unless you just need to drop the temp a couple of degrees and then you'd want it blowing on you, not just into the trailer.

It could work but it's not terribly efficient because you have to leave another window open some to let hot air in the trailer out. So you are going to get a smaller temp drop than if you could recirculate the trailer air back to the AC inlet. In a teardrop it's probably no big deal but just a lot of air exchange and wind going through. The AC probably never gets a chance to cycle down because the compressor is working doubletime.

Regards,

Matt

Yes, I remember someone was modifying the plenum to accept another hose for a return from the trailer. Great theory but that would be getting pretty complex for me at least. How badly do I really want to go camping in the heat?

If you don't want it mounted full time you can hang it in a window like Frederick did in his Fiber Stream or like I did in my Boler. It works great!

We traveled in a Casita 16 this winter. The Casita 16 uses a traditional home air conditioner mounted below the front closet. We used it about a dozen times and it easily cooled our Casita 16. I believe a 5000 BTU unit would have been adequate though slower to cool.

We just bought a Scamp 16 without air and are considering mounting a 5000 btu with remote control in the bottom of the closet ala the Casita. One can't beat the price, around $150, a remote control, a low current draw of 4.5 amps and 24 hour on/off timer.

Our EggCamper came with a 5000 BTU home-type AC and I wish it was a little larger. As long as the sun isn't shining on the camper the AC is fine, but if it's in the sun, the AC helps, but it's still too hot inside. My advise is to stick with at least the 5000 BTU unit and avoid anything smaller.

We are wanting to add a window AC unit to our lower closet area and I had seen the one Norm wrote about at Walmart. It's a Frigidaire 5,000 BTU with a digital display and even comes with a remote. I think it looks great and Frigidaire has been rated as a good brand. Does anyone think the digital model vs the manual model with the knobs/dials may be more risky with all the bouncing and motions from being used in a trailer?
