I think v2 would have a fan on the cold side to increase air flow
@garyl603111 ай бұрын
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.

I'm still in the part about choosing the right amount of aluminum in the cold side, since I'm using a 12715 that's a bit more powerful and I have to fight against the average of 80% yearly rate since I'm close to the shore... the cold fan to the cold side will also prevent it to freeze if you can put this to work in the max power...
@JustBarran2 жыл бұрын
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
@CptSweetCheeksJr Жыл бұрын
One thing I've noticed with my peltier dehumidifier is it's really sensitive to air flow. Not enough and it gets too warm, too much and water evaporates off the cooling fins before it can drip off. I think the reason you only got 25ml is a) you're pushing too much air with that fan ramped up all the way, and b) your fan is essentially preheating the air before it reaches the cold side making even more water evaporate off the cold plate.
@JustBarran Жыл бұрын
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
@dentonator2010 Жыл бұрын
You should be getting a much higher temperature drop across the peltier unit than at best an 11°C change at the beginning. Considering you weren't using forced convection on the cold side. I might have missed it but did you use thermal compound for the connections? With that large of a hot side heat sink, a small cold side sink and running nearly 40W you should be able to get below 0°C. When I've used them, you either need a good sized heat sink or else a fan to keep it from freezing up.
@JustBarran Жыл бұрын
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

Great video: nice work. Maybe I missed it but I didn't hear/see anything in terms of relative humidity drop after running the device overnight? All the other mentions of Peltier devices that I've seen say this approach is best suited to small spaces, as in quite a bit smaller than the room you are in? So I'm very curious what results you are getting. Maybe an array of 10 of those Peltiers could make a dent in your relative humidity? Anyway, I'm with you on those chemical moisture absorbers: really not a great solution. Just as a point of comparison, when I run our split system on dry mode in a roughly 15 square meter room with normal ceiling height (sorry, too lazy to measure the volume), I get about 1 drop of water exiting from the drain pipe every 12 seconds or so, and the result is the relative humidity drops by about 10% over the course of about 40 minutes, from 63% to 53%. This might give you a rough indication of how many Peltier devices you might need to use to achieve something similar?
@JustBarran Жыл бұрын
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!

@JustBarran2 жыл бұрын
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
