I filled up a bucket with bottles of frozen water, maybe 15 pounds of ice total, then put a 6" computer fan at half power, that blow inside the bucket.

Does it work? Well, it is working a little bit. The air comming out of the bucket is colder than the one entering in it. If you put your hand or your face near, you will feel a refreshing dry wind. But that's it. Not enough to cool the trailer, or maybe for just one or 2 degrees.

It took 2 1/2 hours to melt almost all the ice. My fan was using 0.25 amp. It was 80 degree F. outside this morning when I made the test.

To bad!

I would have loved this idea.

Alain

It was in Sportsmansguide.com Camping and Outdoor living catalog. $15 US. page 50. wouldn't have even noticed if it wasn't for this dicussion. :lol.

Al,

I suggest you put a pan or something under the pet cage, if it is not waterproof. The frozen bottles will also act as a dehumidifier. The moisture from the air will condense on the bottles and will drop on the floor if you don't take care.

here are the results

pet cage has a solid floor lol
52 lbs of ice in 20 liter plastic bottles small 110 ac fan on trillium 1300 in the shade of a maple tree.
time--------inside temp----outside temp
610 pm-------88.3------------84.0
625-----------87.3
640-----------85.3
655-----------83.8
710-----------82.8------------84.0
725-----------82.3
740-----------81.7
755-----------81.3
810-----------81.1------------83.5
825-----------80.8------------82.4
840-----------80.4------------81.1
855-----------80.1------------80.1
910-----------80.4------------74.0 sunset and ice completly melted

opened trill up and was greated to nice dry air even if it was 80 .
it took a regular gym bath towel to soak up the water in the bottom of the cage . Nice experiment but where are you going to get 50 lbs of ice every 3 hours?

i tryed the experiment with 10 bottles this morning . it could not keep up with the sun load and temp kept climbing untill i i opened the windows and let the breeze do its work so 26 pounds of ice is not enough .

Window air

Hello,

Our 1982 Scamp 16' we just bought came with a window air installed in the door side rear window. It's a smaller GE Carry Cool that doesn't look too bad. It sticks out the side of the camper about 4 inches and likewise on the inside. I've seen some mounted so the entire unit is sticking out the side of the unit about a foot. Looks tacky in my opinion. While I would prefer a nice roof top unit, this is what our trailer came with. Heck, I'd like a brand new trailer. Our window unit makes it like a fridge in there! No pics right now...sorry.

The "fan blowing over a pile of ice" is how they used to cool movie theaters and is the reason A/C is sometimes measured in tons, with a ton of a/c being equivalent to a ton of ice melting over a specific period of time.

Tacky vs cool

My '89 came with it installed in the back window. That was the way they use to do it.

At first, I thought ''eeeeuuuuwwww.'' But, it's amazing. It really cools during the hot Texas summers. Now, it doesn't bother me so much. The more it cools me down, the less I notice it.

We have a lot of innovative owners on here that have come up with some really great installations. You have many options, not just the back window. I'm thinking of putting mine in the bottom of my closet. Problem is, I'm not sure I want to give up any of my storage space just to get it out of the window.

window works for me

take it out when you dont need it . no new holes to be filled in later when the permently installed one goes south ( breaks down)
Does not take up storage space inside . And best yet you dont have to get up in middle of the night to adjust temperture lol.
