I think v2 would have a fan on the cold side to increase air flow

Larger heat sinks on both the hot and cold sides and a fan to pass the air first over the hot side then onto the cooling side. This will increase the extraction efficiency by creating a wringing action when the air cools.

I don't think having a fan running full on the cold side would work in this case. The cold side doesn't get THAT cold. Having a fan on full would draw too much warm air raising the overall temperature of the heat sink preventing the air from reaching dew point and atomizing the water on the cold side. My suggestion: You would need to drive the cold side as cold as you can by isolating the cold side into a smaller volume than "the entire room." Pass warm air into this volume slowly keeping the heatsink fin temperature below the dew point. (temp sensor on the cold side heat sink and a PWM controlled fan circulating the air maybe?) The fan should not be strong enough to create a breeze to atomize the water droplets. A second peltier device stacked may decrease the overall temperature a bit more, but doubling the power requirements. Peltier devices are not very efficient with thermally speaking. They are convenient and space efficient. Another thing you might try is to pass the COLD exit air over the hot side. Peltiers create a temp drop between the hot side and cold side. The colder the hot side is, the colder the cold side is. Since the purpose is not to create AC, the cold exit air would help in some small amount to make the device slightly more efficient. Just be careful to not create too much of a vacuum of the cold side with the hot side fan, and in result raising the cold side too high for condensation. Maybe instead of a cold side fan, have the hot side fan draw the air with vacuum. Rate can be controlled with a louver attached to a servo.

@@JustBarran energy consumption values would be great!!

Thanks, I have been so busy lately haven’t been able to do much editing and posting but hopefully soon life would ease up. I really appreciate this comment.

Hahah thanks, you get me ❤️🥹

Hahahaga thanks a lot bro, this means so much. I'll give you back that time don't worry 🙌🔥

😭😭😭 don't remind me

Thanks, it is still a work in progress

Hhahaha happy to make them for you 🙃😂

Hahahshahagaga I know right, wettting after wetting, iwer george would be proud

Thanks mate

I know right 🙌

Thanks bro, hope all is well with you

@@JustBarran Things cool bro. Good job on the channel!

That's actually pretty cool, I mean I still expect some losses but you are right once both sides are Utilize correctly

I would prob put it to the test first, and see how cold it gets, generally you wouldn’t need a fan on the cold side if you are doing Dehumidifying, and the bigger the aluminum as in my video the higher the lowerest temperature would be. The important side is the hot side because that needs to be cooled as best as possible

That’s a really good point come to think about it. I actually though the more airflow the better but you have me thinking now. I think one of these days I’ll prob have to revisit the experiment and see if different speeds give more or less water. On the other hand I need the fan to run as fast a a possible to cool the hot side so that’s something to note also

Yea I used a thermal compound, but I was a bit surprised also I wasn’t able to get below 0, could also be a limitation of the powersupply or these peltiers I have. One of these days I would do a second try at this and use some lipo batteries instead

@@JustBarran with mine they're rated to go to 60W I believe. They say 12V but I've gone to a lot higher to get to 60W.

Yeah, I feel I would try and push mines a bit more next time around, thanks

yesssssssssssssssssssssssssssss thanks

Yea but it's not the best for storage rooms

Oooooooooo this actually is from my old computer but It has an intel mount 😢

@@JustBarran Out there on the market there is adapters to convert from intel to amd. anyway the cpu will come with his own heatsink cooler but I may think to buy a water cooler for the cpu

Pun intended

Sorry for this late reply. This specific unit didn't make a dent in the relative humidity. You are correct that it would work best in a small closet. Also this isn't optimized much also (cooling on the heated side and surface area/cooling on the cooling side). I would add that after this project I both a off the shelf Peltier dehumidifier, inside has two high power peltiers and a really nice fin array that I have running 24/7 and thus brings the humidity in my lab (about 86sqft) from 70% to about 50%. But this is really optimize for the job. If I took some more time and get a better fin maybe cut down on the surface area of that heatsink so it gets colder as in smaller heat sink it would work better. Also there is the fact of the due point/temperature of the room. With regards to your AC, I think the airflow plays a big part in that as AC units move a lot of air and by lowing the temperature in the room it also affects the humidity. I don't think peltiers can complete with a refrigeration cycle system. As in the case of my lab ( the pelitier dehumidifier that has two pelitiers) it takes about 2 days to full the tank 70oz, I find it works really good. amzn.to/43ovl4w this is just for comparison. Hope this helps. I am do a follow-up video sometime in the future where I revisit the design but right now I just don't have time. 😢

@@JustBarran Hey, that's great to know! Would you be able to share a link to the high powered Peltier system you used? It sounds like it is accomplishing something comparable to what my AC unit is doing, humidity wise so I'd love to compare the power consumption and price. My guess is the Peltier device would need less maintenance considering there are fewer moving parts and no refrigerant involved. So yeah: I'm really interested if you have a link! Thanks again for the video!

Sorry for the site response but you can find the links in the description of the video

@@JustBarran Hey, actually I was asking about the off-the-shelf Peltier dehumidifier with high power Peltiers: I don't think you linked to that in the description?

Yeah, you are correct. I could also use some nylon standoff/screws to help reduce the heat transfer. Things to add in the V2 😭

That’s a really good point, Ill see if I can plan out a test, but think a Compressor base AC would produce more water in a shorter period, could program a microcontroller to put it on in small periods but it also would be activly be using energy to cool the room also even in dry mode, while this operates more passively (35w) on the due point effect, and I thinking I could even run this off a small solar system.

Yep something so, well humidity is water dissolved in dissolves air, higher temperatures means that the air can hold more water but this causes the humidity to drop also because as the hot air raise it would move the moisture up

Just like my life 🤣

Also did it actually help , like did you notice whether measured or felt different ?

@@usmanmohammed8949 Well seeing as it only produced 25ml in 8hrs I don't think it would make that big of a difference, It is presently in the lab on and working, No noticeable differences, but it clearly is doing something, I think there is a lot more to improve on also so version two would be in the pipeline.

Hi

@@JustBarran interested in helping me setup a hydroponic greenhouse setup? building them- selling them - create a brand- expand worldwide eventually creating the materials ourselves/ mining

I never said it was a good one 🤣

ey some people dont even have that much to drink
