watercooling idea

[SteenkyBastage]

ok, brainfart time...er, brainstorm

i've been thinking this over for a while and wanted to know if anyone thinks this will work or if it's just plain not possible.

i read that a dehumidifyer will cool the air down, thus causing condensation, which collects at the bottom of the device. then after the air has been dehumidified, it warms the air back up and exits the device.

ok, provided the above statement is correct...

could one use this in conjunction with a bong, for a twofold purpose.

1) modify the dehumidifyer to recycle the cool condensation (water) back into the system.

2) modify the dehumidifyer to NOT warm the air back up, thus enableing the SAME air to be used in a closed loop (the air would be cooler, too).

heh, my guess is that it's not gonna work for some reason or another, or else someone would have already "invented" this method. but hey, you never know.

I have no idea if it'd work, i'm still looking for a good starter H2O sys (be cooling looks nice...) but i got a question:

When you say bong, do you mean a computer-related part, or a drug-related part...? I'm kinda confused on that...:confused:

That is an interesting idea.
I do not know for sure, but the dehumidifiers I have seen cooled a metal coil. Water condensed on this coil, just like on a glass of a nice cold beverage(cider please), and then drips into a tank. I do not think it does anything directly to the air temperature. Of course you do have the effect of the cold coil and the heat coming from the compressor.
You might be onto something by adapting the refridgerant unit to PC cooling. Instead of the coil you could have a heat exchanger/water block apparatus for the processor.

There is a tip on the front page under watercooling that explains "bongs" I think it might be titled "atomic tower". If you are thinking of water cooling you should read the article.

They are a small evaporation cooling tower that looks like a large drug related apparatus.

You have the right idea as evaporative cooling is dependent on humidity. The drier the air the more effective the technique. I have been doing a lot of research on this and the results for my system was that on an average day I could achieve 3C below ambient but on wet days (100% humidity) it was only 1C. The change was sufficient to affect the oc I am using. De-himidifiers are very expensive so gave that a pass.
Have just installed a refrigerated system for less than $20 (£15) and it is working great as you can see from my sig. May write an article later. Now looking at sub zero cooling from the same setup.

I have been working on this concept and will give some ideas.
The system I used was 2 10l stackable plastic containers. In the lower chamber I housed the pump and the pipe went to the w/b and the return pipe to a 'T' junction in the upper chamber. The pipe was fed through the upper chamber and then looped back through the chamber back to the 'T' junction. I made small holes in the tubes inside the chamber and hung cloths over the pipes so that the water soaked into the cloths. I mounted two 80mm fans in the lid that blew air over the cloths. The air was vented outwards via slits cut into the end walls of the chamber.
The idea I had for a dehumidifying circuit was to use the same concept but not cut the slits but instead make a perspex tunnel above the chamber with a 80mm fan sucking air out and over a heatsink cooled by a pelt. A second fan would then push the air back into the chamber. A drip tray below the heatsink would return the water back to the lower chamber.
I never got to try it as I went direct to refridgerated cooling as per post above

ahhh, this would explain why it may not work. or not work well if it does.

i guess, tho, that the dehumidifyer could still return water as a "self filling" system, maybe.

the overall idea i was hoping for was to have a closed loop bong setup. as in, all the air stays in the bong, just gets recycled; as well as all the water staying in the system and getting recycled too.

the heat would be exchanged via dehumidifyer OUTSIDE the loop. thus cooling the water and air, but still warming up your room.

if they work off cooled coils, then i guess the air wouldn't get nearly enough cooling to be used in a closed air loop.

oh well, thanks for the input, was worth a shot.

i have one in my basement
they heat up the room belive me


its a good idea

but in theory it wont do anything

the lack of humity caused by the dehumity will cause the watter to evaporate quciker getting rid of more of the heat but the over all raise in temps of your room will just add it back on

your best bet would be to modd the dehumidafyer so the condening radatior was sitting in your resoviwer

and the hot air blew into another room or outside or something

but you have to keep in mind that these things will freeze up in a second if the air gets to dry.

yeah, that was why i was looking at making a "closed loop" for the air. as in, only the same air was used, just circulating thru the tubeing to enter the bong again after it's been dehumidified.

if that could be accomplished (in theory) the higher room temp wouldn't make much of a difference (except to your case temps, i guess).

when i get some free time i'll see about drawing up a visualization. i guess it's kinda hard to understand just by reading, not seeing.

what if u had an old humidifier, tore out it's cooling coil, and used that to cool the water, kind of like a peltier... except in the tank instead of right on it...

I think you'd need a very high-capacity dehumidifier to pull this off. A cooling tower can put moisture into the air much faster than most consumer-grade dehumidifiers can take it out.

I've considered something similar. Instead of using a dehumidifier and a closed system, I was going to blow my intake air through a dessecant box. It would result in a little better cooling, but the dessecant would have to be changed pretty frequently, so I decided against it (for the moment, anyway :) )
