- Homemade Dehumidifier! video shows how to make a simple Dehumidifier. very low power consumption. (about 10 watts). *works by pumping ice water through a series of copper coils *and collecting the resulting "condensate" in a drip pan. note: if you keep the copper coils clean, the water that is produced is essentially 'distilled water'. as a preview to my next video, i've included a short segment in this video showing how i converted the unit to a fully usable AWG (atmospheric water generator). *an AWG is just a "food safe" dehumidifier. I'll be posting a full video on that in a few days. a few details: copper coil is 1/4". pump is standard aquarium water pump (AC powered). for off-grid operation just use 12VDC water pump and hook to battery or solar panel. *use the longest section of copper you can get. the more coils you have, the more water you can extract out of the air. i'm thinking of trying a 100 foot piece... with a more compacted coil. also consider adding a fan to help increase water production

If you make some kind of angled tray underneath the coils, with two gullies running parallel to them, you will minimize evaporation of the water back into the air. The majority of the pooled water will be covered, except for maybe 1/4” at one of the ends to allow the water to drip down from the two gullies.
One could even plumb to a water container inside your refrigerator and forget the ice. Add a hydrostat switch in the pump power and you are MacGyver. Awesome and simple proof of concept - thank you!
That was what I was thinking myself. I was thinking chest freezer.They are very low on energy consumption. Should work. I might try it just for fun! :)
Good Idea. The coils outside the fridge could be behing the frige where all the heat from it is put off. Even more effective!
living in an old house basement I have problem with high humidity. Your idea saved me from humidity. I bore 2 holes in the back of my freezer and keep the coolant container in the freezer. It runs Auto coolant that can stay liquid at low temperatures. From there i run the main pipes in my whole house. Each module have a fish tank pomp that sucks coolant from the main pipes and runs it in the coil in each room. Best idea man, thank you.
Your whole house I thought you just live in the basement
yeaa i thought you lived in the basement???
Brilliant idea using auto coolant!
This just put into perspective how a dehumidifier worked! Thanks
Genius! You’re so generous for sharing your work. Thanks!
@Tere O -
Are you mechanically inclined?
Going to make one?
@@RobertECheck and are you nothing more than a internet troll keyboard gang banger who just goes on comments under the comment section and puts his two cents in, like it even matters 🤣🤣🤣🤦 joins 12 years ago and yet still has no subscribers 🤣🤣🤣🤣 more like your social media inclined 🤣🤣🤣🤣🤦
Very cool, I'm trying to build one of these (AWG) to try and pitch to someone to fight the drought out west
Great example! So what would be wrong with using a chest freezer to cool it down and cycle the water.
Just a thought
Relevantly Essential & Nice :-)
How efficient is it?
For example, liters per hour or per day?
Brilliant DIY !
Hope police don't think your making moonshine : )
Aren't US folks allowed (now) to make stuff at home for personal use? I seem to remember that from an article.
I think I would add some type of cover to your drip tray, so the water that you have collected doesn't re-evaporate. Thank you for the video.
That would stop the colection unless you changed the contained air every now and then
Ivan Adriazola He means underneath the coils. The cover could be at a slight angle so the water would creep toward one end and then drip down into the tank.
@@GodsMan500 oh, i was imagining a fully closed cover
Or he could just add an exhaust pump to redurect the water outside
Trying this at home!
What if you connected your coils to the cold water pipeline from the house and the other end of the coil drips the water outside. So instead of a closed condenser system with ice water use the water pipeline would that be cold enough?
Correct me if I’m wrong but AWG design needs electrolysis buffer.
Dehue design is good proof of concept.
Data collection and subsequent report would be helpful.
I know this video is pretty old, but this seems like a good place to pose a question regarding dehumidifier efficiency. My unit produces 45 pints a day but exhausts 600 Watts of heat when it's running - a bad thing. Suppose the condensate pump delivered the water to a radiator mounted above the exhaust? The heat, or at least some of it, could be used to heat the condensate, which was then dumped into a floor drain. No energy cost except for having to enable the pump. I can envision a free-standing unit that would straddle a standard unit and have a sliding mount for the radiator height. I'd buy it. This came to me when trying to figure out how to evacuate the heat from an oven after finishing baking.
cool idea(no pun intended), but why not use a couple peltier moduals in stead of a cooler full of ice? would make your design smaller.
In one day how much water will get from that
Now run hot air over the coils from your solar air heaters and you'll probably get 10x the water as a atmospheric generator.
That's how
do you know how make?
Can you explain this in more detail?
Thats utterly fasle.
Hot air can keep more water, but just heating air does not change the water content "x". Hence more energy is required to cool down the air again to a over saturated state below "φ=1" to form condensate. Therefore your statement is false, if you dont somehow add more water to the hot air.
Good information. Needs a solar powered pump, maybe. Best
hi there and thanks. if interested, here's a link to a short video i just made showing the AC water pump (used in this project) alongside a 12VDC "solar panel powered" water pump. th-cam.com/video/DU6QyYj_CuQ/w-d-xo.html
Is this verry effective.
I wonder if the coolant has to be ice cold or just colder than the ambient..real interesting build
The temperature difference needs to be about 20F. So it doesn't need to be "ice cold", but that does make it last longer. The ice can be made in your freezer with ease by freezing water bottles. I was thinking of using dry ice as it's really cheap and I would think would last a long time, as well. Experiment time!
Dry Ice is made up of the same stuff we exhale. As long as the room is not enclosed, the CO2, being heavier than air, will flow to the floor and out any doors that might be open. Also, if the container holding the CO2/DryIce is closed, the CO2 will stay inside the container. It doesn't build up that high of pressure to blow the container open.
And, if the dehumidifier/cooler is built right, it could be made where the container is outside and air is cycled through it using fans.
So, yes, if you are in an enclosed room (relatively small at that; bathroom/closet perhaps?), then the sublimating DryIce, turning into CO2 gas, could suffocate you. But that would be an awful lot of CO2 to replace all the air with.
@@chelseat1420 not true
Theoretically it just has to be under the dew point that you are aiming for, though I assume that, to a point, the rate of condensation would increase as temperature decreases.
That works for outside, but I would like to use one inside which makes your not an enclosed room a problem
Nice, if you have ice.
Hi how long is the copper coil? You mentioned the diameter is 1/4", but not sure what the length is.
Would guess 50 feet because he mentioned wanting to try 100foot (he said use as long of piece as possible to extract the most water at one time)
@@PersonalStash420 you did everything but answer the question, lol
How is it powered? How much wattage...? Etc.
12V Dc 5Amps - he said in description about 10 watts
how cold do the coilds need to be (just a rough estimate)?
I know this is a bit old, but you need it to be around or below the dew point. Essentially dew point is when water starts forming on objective. The colder it gets, the more efficient this unit will become (hence why retail dehumidifiers use freon instead of water. And dew point will change depending on the level of humidity and temperatures. So if your house is hot and humid, your dew point is significantly higher.
Started making one of these but can't for the life of me get the water cold enough. Any tips?
are you using refrigerated water with the ice &/or gelpacks? You can get your water to near freezing- as long as it's still a liquid, probably all that counts.
If we add some fans will it increase dehumidification rate ?
Yep!
Thats how commercial dehumidifiers work too. It would also increase the rate at which the ice would melt which would lower the overall effective working time of the humidifier.
@@stephencarlsbad but wouldn't it have to be an enclosed system? I mean pushing air around is going to make water evaporize quicker and if the whole assembly isn't contained, some of the water would de-condense and go back into the air again, wouldn't it?
@@lenajackson5448 The rate that water evaporates back into your room is miniscule especially when first starting your evaporator since high air/water density would prevent water evaporation. The solution would be running the water back into a container that has a relatively small opening to prevent water from evaporating out of the top of the container.
I would get some 2” pvc and some copper sheets and line the inside of the pvc pipe with the copper sheet and slide these coils into the pvc. All your trying to do here is take the air around u and bring it down to a dew point, if u can get it colder even better lol put a small pc fan on top of the pvc pipe to stream ambient air into the pvc pipe continuously and let the pipe fill up
Hi, nice video please also add written instructions on building the dehumidifier in the description to make it easier to understand. Thank you.
To remove water, add water to the system.
yea the main part which he forgot to mention
Would salt water condense more because its denser?
Saltwater does not form a vapor. The water evaporates, the salt is left behind.
I think salt water tends to "push out the cold" faster (transfer the cold faster).
So if you want to condense more water quicker, it just might speed the process up. But once the cold is gone, it's gone.
The reason you never want to use ice water to keep food cold in a cooler- it'll get things in there cold FAST but then melts quickly and won't sustain.
salt water, I meant. if you freeze salt water for ice instead of regular water
Oh you already made one.
Now to next video and see how much water it collects and if it works without using ice.
If you would have one pipe from the bottom of the cooler and one from the top of the cooler, you don't need an electric pump ;)
That is a good idea because heated water will rise and cool water would fall right? It's just how do you get a gapless system without having air bubbles?
But How Ice water healps to extract water from air???
hi. the ice water cools the tubing down to below the dew point temperature. when that occurs the water will form on the tube 👍🙂
@@desertsun02 thanks.
Can you use something else cheaper than copper?
maybe aluminum tubing but that's not easy to find where i live
When Mark Wahlberg teaches you how to beat the heat. Kidding aside, attaching the copper in the front of a fan basically makes it an air cooler, right? Like what you did in your older video? Will that make it more effective as a dehumidifier?
hi. i've heard that using a fan can help but i haven't tried it yet
how do you know it's not water condensating from the ice water inside the tubing, like how an glass of ice water gets condensate on the outside of the glass?
well,actually...that´s the whole point
What else would it be?
Good question. I think he would know if the water he started with began to decrease as he harvests then atmospheric distilled water.
@Zack Moritz well the water inside the system does not soak through the coil or tubing, so the water that collects on it is solely from the atmosphere outside of the coils
I 🤔 what the Doctor is meaning is that when you have a nice cold beverage in a solid glass cup, etc it magically seeps through the cup 😆
I'm making plans to build an atmospheric water generator in Africa. I believe I can make enough water to grow crops and livestock
That’s sweet use the water for hydroponics you’ll save a lot more
@@nickquint1499 aquaponics
Even better
Did you make one in the meanwhile?
So I live on Hawaii. I need a way to put a small unit in a box with weed drying.. cannot afford a dehydrator and live off grid where power is is high demand.. any ideas for a small unit like this.. connected to a small solar array.. ? Shoota
Dry ice solar pump
Now follow my tip and get more moisture, use one more bucket or frame to place 2 12v fans, and some holes that air comes out, and u will get more moisture.
How?
@@terrellmoodi735 more air over the coils means more moisture comes into contact with the copper lines.
@@5avagetac037 but moving air has a tendency to evaporate water or send it elsewhere, doesn't it? You'd have to tightly enclose the whole system I'd think
@@lenajackson5448 not really, if you tilt the pipe to a 10 - 15 degree angle, water will collect before it gets the chance to evaporate. Underneath, you just built a close-off water collection system, and it will prevent evaporation even more. Also the direction of air matters. Instead of blowing the air AT the pipe, you pull air through the pipe.
but isn't the condensated water just the water from the bucket?
hi there. no, the condensate is actually water that is pulled out of the air. the water in the bucket is just used to cool the pipe, so water will condense. 🙂
You may not need the pvc's and just add bamboo or phragmites canes.
keep in mind that the dehumidifier collects dust too, so how can that be clean water?
hi. as long as you keep the cooper clean, the only thing that will condense out of the air is pure water (the dust will not condense). it may be in the air, but it won't condense ✔
@@desertsun02 then how do air conditioners get bacteria in their water?
@Graphene Pixel air conditioners along with dehumidifiers and things like that have all kinds of components and parts in them (like gaskets, sealants, rubber parts, solder joints, plastics etc.) all the extras can leach stuff into the water (plus the pipes in those get dirty pretty quick). with my setup it's just the pipes, so if you keep them clean it works great.
Youre pumping water thru a copper coil......wouldnt it just condensate thru the coil and add humidity?
hi. that's basically it. it cools the pipe and water condenses. (not through the coil though, but on the coil). it pulls water out of the air.
@@desertsun02 pulls water out of the air and redistribute it. Pretty redundant 🤷♂️
I wouldn't call this distilled water. That is done by heating water and catching the steam. This process catches water at room temperature. So bacteria and whatnot isn't cooked off the droplets. That said, it's still most likely safe to drink.
hi. this type of water purification is sometimes referred to as 'natures way of distilling water'. only pure water will condense on the pipes (the condensing naturally rids the water of all bacteria and pathogens) so it's essentially the same thing as regular distilled water. (you just have to be sure to keep the copper pipe very very clean so the water doesn't get re-contaminated) ✔
Hi u need your help to make this project for school kids pls describe the material list it's very urgent I have to submit this project in 3days
Trying to understand how this would work as a dehumidifier, the water being collected is just condensation from the cold water. How does this remove water from the air?
hi there. the water that condenses on the pipe (and is collected) comes straight out of the air. the cold water in the pipe is a closed loop so none of that escapes. (think of the water that condenses on the pipe as like the water that condenses on the outside of a drinking glass when you have ice water in a drinking glass on a humid day. i hope that helps 👍😎
@@desertsun02 Oh I see that’s awesome! What I thought was wrong. I understand now thanks man!
@@desertsun02 Very simple and straight forward answer. Thanks.
@@dr.feelgood2656 yeah, it's the cold attracting (condensing) water from the air to the pipe. Humidity collects on cold rocks the same way.
Helllo, I watced and wathced and watched again, I get the system but still I did not get exactly how it works. Actually I need this system I am really interested with it becasue of that but I guess you "have to'" spare more time to explain how its works(scientifically)
The cold copper surface condenses the water vapor in the air and it drips down
I don't believe in God but God bless you. Thank you so much.
This is the First time iv seen this lol. Godbless you Dave. The High Power is real.
its ok, some people don't believe the internet is real probably
