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.

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.

I took inspiration from your vid and made a similar system, plumbing the water container inside a small fridge. The first version was just like this, just with a smaller water container (an ice cream pot with lid) and shorter copper tubing (2 meters or 6,6 feet). It worked, but condensation started forming on the plastic hose right after it left the fridge, so it was a mess. And I felt like it was not getting as cold as it could. So the second (current) version I added insulation to the plastic hose to prevent premature condensing, and made a copper serpentine to fit inside the ice maker of the fridge and plumbed it between the pump and the external coil. Then replaced the regular water with antifreeze car liquid to make sure it doesn't clog. Now it's drawing about 120 ml per day, but the exterior of the container is condensing as well. I think there's room to add a longer coil and a stronger pump, but right now I'm out of time and money to do it. I'm thinking about replacing the coil with 10 or 15 meters of aluminum tubing. I'll update when I do it.

I understand that humid air makes the compressor work harder so this might cut your bill. I am interested in any way to alter the air going in to lower the work the compressor needs to do.

@dingzhuxi 9 ай бұрын

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.

@callmepistol Жыл бұрын

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?

@moteroargentino7944 27 күн бұрын

Late reply but unless your home is significantly more hot than the outside (or the outside more cold than the inside) there won't be enough temperature difference to condense humidity properly. As an example, when you distill liquids in a lab, you refrigerate the condenser with tape water, but what's running through it is literal steam. So unless you live in a sauna your best bet is to lower the condenser temperature as much as possible.

@korishan 6 жыл бұрын

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!

@korishan 6 жыл бұрын

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.

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.

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.

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.
