cooling your tent or van

[FIGJAM]

Finally got done with my unicooler. A friend of mine helped me make a steel top with a hole(for adding water) and plug so I don't have to constantly open the top since its pretty snug. Not the nicest looking box but it was blowing about 70 degrees in 5 minutes.

beutiful!!!!!!!!!!!

Thanks FIGJAM, this fan rocks! I am suprised at the amount of air it moves. I went with a pumpless design ... using wicking humidifier filters. I have about 90 sqinch of filter surface area. I ran a 2 hour test yesterday and it blows a good deal of cool air, and the filters stayed moist the entire time. I went through about 2 liters of water. I may post pictures later in the week.

I'm still concerned about those wicking filters glogging because of their fine nature.

Hope it works well in the dust.

Make sure to report back after the burn!

I am covering the outside of the bucket with air filter material to minimize any dust on the wet filters.

Hi FIGJAM,

Quick question: Have you tried adding a third layer of Dura-cool padding in the bucket? If so, did it help with cooling or did it create some sort of problem or was counterproductive? Almost done with the cooler and huge thanks for putting this together

Groovy --

[FIGJAM]

I've been using swamp coolers in most of the houses I've lived in.

1 layer is all we ever used.

With the bucket the 2 layers serve a dual purpose, but this isn't a case of "more is better".

[kstlfido]

I'm suprised the messurement was'nt the same, but you get the idea.

You can also staple the seam on the outside pad.

Just pull up a bit on the inside pad.

I siliconed the edges together, worked fine. Do you have the correct outside pad measurement?

[FIGJAM]

Just remeasured to make sure.

The outside dimention of my tube is 33.5"s.

Taken by running a piece of string around it and then messuring the string.

The pad is about 1/4" away from the holes in the bucket all the way around.



As long as the fan can fit in the middle of the inner layer you're fine.

[garyt]

It's

beutiful!!!!!!!!!!!

Sigh.

Thanks Figjam! It means a lot coming from you! Although there's still a couple of kinks. I've silicon the fuck out of it and water seems still to be able to leak a tiny little bit. I'm trying to add a 12v timer and switch that doesn't take up too much juice so it kicks on by itself at 6-630am. Don't know how to do that yet. Was thinking maybe using a relay and my solar panel as the trigger.

[FIGJAM]

Take all the guts out, dry it completely, and using your finger, spread a layer of silicone over all the interior joints.

I would be very surprised if THAT does'nt fix it.

[strangeloop]

Ready for action!

[FIGJAM]

As "worth it's wieght in"?

[strangeloop]

Solid Gold!

I made a similar one last year with your help. I'd love to make a bigger one, but this is about as good as it gets packing it on an air plane.

Have done that twice. I can see a really really small wet spot after like 10-15 minutes. At this point, I'm glad its working and all 9 gallons of it did not leak out after an overnight test.

Please post filter model and size.
Also, what would you say the air temperature and humidity was where you were running it, and what was the output temperature?

Hey Figjam
Any advice on connecting the fan to the battery, I have never connected anything directly to a 12v battery before and I don't want to do something stupid and fry myself! I have two gator clips that I'm going to solder to the negative and positive wires of the fan. Do I just connect them to the battery and I'm good to go? Should I connect one first and then the other or does it not matter? I think you answered this or a similar question before on this thread, I looked but I couldn't find it.

And by the way, you are the bomb

-strangeloop that cooler is a golden thing of beauty!

[strangeloop]

Thanks jeskalgh,

Last year I hooked my uglier cooler up to a Sears garden tractor battery with gator clips. It worked wonderfully all weekend, running about 2 hours a day. Just keep the wires separated and shielded from people.

This year I'm bringing a GoalZero battery and solar panel to keep it (and other things) powered. I've tested it out and works great, unless we have rain all week and I can't charge the battery.

Unfortunately this setup is expensive. I got a really good deal on mine.

[jeskalgh]

Thanks strangeloop! I was a little worried and didn't want to do it wrong. Mines made out of a deli pickle bucket and it says DELI PICKLES in giant letters. Its to funny to cover up, I think I am going to paint giant pickles all over it actually (if I have time!). Those solar kits are sweet, I actually looked at those same ones when I was trying to decide to go solar or not. I think I will save the solar setup for next year when I upgrade. Keep your fingers crossed for sunny weather on the unpredictable playa this year!

[FIGJAM]

That unit only has 14AH!

For that price you could buy 3 115AH costco deep cycle batteries.

One of which would run the cooler all week for 6 hours a day without having to recharge.

But if you're happy with it, go for it.

Connected to Fan: http://ecx.images-amazon.com/images/I/3 ... 0,300_.jpg

Why?
1. So I can easily connect and disconnect without handling the clamps.
2. The plug connected to the fan has a 7 Amp fuse to protect from shorting out the battery.

[FIGJAM]

I put a switch on my very first bucket cooler, mounted to the lid.

Had both pump and fan hooked to it.

Did'nt bother to put them on the bucket coolers after that, but it was convenient.

[jeskalgh]

Thanks everyone! A switch would have been a convenient idea, I actually think I have a switch around here somewhere from another project. Anyway I just tried it out with just my gator clips and taadaaaa its works, and I didn't electrocute myself. I can feel the cool air blowing out already even though the humidity is pretty high outside, I cant wait to see what this baby can do on the playa!

[LadyOcelot]

Mr. Fig jam,

Long time lurker. The build on my unicooler is coming along nicely. Curiously, do you recommend keeping the deep cycle battery inside or outside a yurt? A ton of thanks for all your time and energy in this amazing thread.

[FIGJAM]

Depends on the type of deep cycle you have.

Mine are AGM (absorbed glass mat) that can't spill or leak or off gas.

So they are inside with me.

If you have any kind of flooded acid battery, they off gas fumes and should be kept outside.

So a discise may be in order. (now where did I put the fake mustache and glasses!)

[ShreddinPB]

Hey, So I did my final build and everything works! One thing that is bothering me tho..
I didnt have any 10gauge wire on hand so I used a screw. Water seems to only flow out of all the holes if the circle is totally level.

Does this mean I made the holes too big so there isnt enough back preasure?
Should I use a smaller hose or just make a new circle with smaller holes?

I am using this pump
http://www.ebay.com/itm/380461971949?ss ... 1439.l2649

Also piggybacking on the other question.. I am using SLA batteries.. does it matter if they go inside our out?
They are sealed so they dont let of fumes right?
are they more efficient if kept cool?

[FIGJAM]

I think your holes are to big.

Try a paperclip.

Look those batteries up on the internet.

Some SLAs still vent and I'm not going to give advice that might kill you.

I don't know you well enough!

[ShreddinPB]

I wish it was the first time someone said that
I will make smaller holes!

I was thinking about making them with a hot thin knife so that maybe they spray out? fan out the water? Thats probably over kill

I'll just keep the batteries outside then, maybe run a switch inside lol

[FIGJAM]

The pump don't produce enough pressure to create a spray.

Do the holes and if they are a little small you can put a single hole on top of the hose opposite where the T is to allow better flow.

If you have the right balance of size and number of holes you won't need that.

You can change the design any way you want, but don't blame me if you don't get the same results I do.

My Rubbermaid Slim Jim Cooler

[kstlfido]

Hi Figjam-

I did a little measuring tonight...

Previously I had cut a 33.5 x 13" piece of duracool pad; flat on a table. When joined into a tube it's diameter was too large for the bucket.

So I measured my tube with a piece of wire. Circumference was 37", 3.5" too much. I assume this is 'stretching' of the outside when rolled; as it is a pliable material.

Opened up the tube. re-cut to 30" in length. made into a new tube, fits perfectly!
