That's cool(no pun intended)

u reversed the sides

I can't believe you said that. This is not efficient cooler... For this to work, It would need so much current that it would blow the Peltier and the whole system very easily!

It is not meant to cool room... it is meant to just blow cool air on you

there will be some evaporative cooling from blowing air over the water

Not if you change out the hot water with really cool water (especially if you use ice)

no worry gamers I meant if you replace the heated water with cool water. But either way, peltier is just pretty inefficient.

Where to buy heat sink

You're wrong lol The fan at the top of the container keeps the water inside cool, so the heat coming from the peltier would be dissipated through the holes Due to this, the water won't heat up enough for the cold side of the peltier to slowly become hot 🤷

Nope it will not work mahina lang magpalamig ang isang peltier module sa isang room halos wala pa ngang epekto

Me who is annoyed of seeing comments like this in every *how to make an air conditioner* videos : "It would just heat up the room instead of cooling it down"

Couldn't agree more. Unfortunately there are still some very deluded people around who refuse to be told.

"This heat sink has about 0.08s to transfer heat before the air exchange around it" Can you please explain more that sentence?

I dont have such an room , but for example around 40-48 squar metres you can cool it with an power consumption airco around 1000 Watt, so i have one room from 5x2x 2,5, so i need 25 squar meters officially i need an cooling object from 500-600 Watt/hr to cool it down. But in some messages i read you need at least 20 watt p/squar metre, so in that case i need at least 500 Watt. I now tried to build some peltier cooling units from total 375 Watt, i need for that is one Peltier from 100 watt, 150 Watt and 2x60 Watt. The cooling from this units wil be with water. It also depends what stuff you have in the room like computers, lights, and yourself an working person gives around 170 Watt/h on heat per hour, do you close ventilation on windows, do you have double glasse on your window. That sorts of stuff is important or it can cool or not, the room. So i think it gonne work for me with the units with totallary on 375 cooling consumption from the peltier cooling elements. When you buy an airco sometimes they say it has an cooling co-efficcient from 2400 Watt, so really thats an Energy language they use for the cooling effect, its NOT your power consumption, so a litlle tricky.. So over 2 weeks i know or my units wil work or not. Its auxullairy very simple, if you can warm up your room, with an heater from 500 Watt for 3-5 or 10 degrees, why you should not can cooling your room inverse with some cooling elements on the same way. So in the example here, this would not work, because the heater warming up the water and get cooled with the fan and on the other side the same story, the transformator uses or making heat, the fans also, but most important the water gets warm and also get into the room, so you need transfer the water if possible outside the room with some water cables also the transformators produce a lot of heat and the men in the room is busy using also giving also some heat, if you reduce the heating energy into the room, you probaly can cool it with around 400 Watt.. Auxullary i never try what you saying, but i am sure i can coole one toilet good and the temperature wil goes down with 1,5-2 degree per hour with the peltier from 60 Watt, but only the unit and the fan will be into tha room. And for sure i have some bathroom from 2x2x 2,5 and with 150 Watt i surrely think it can be cooled and temperature cans go down every 1,5 hour with one degree. I am not sure you can deal with it on that way you put the power consumption is the same as the free cooling energy calculation they use by selling airco"s in advertisings, you now they sell an airco with an capacy from 3500 Watt, that almost not allowed to put such high amperage into your living space, if i look than for the real consumption from an airco the powerconsumption is far lower may only or just around the 1350 Watt or something.. So what you say i gonne test it over an couple weeks, but i thinks its possible to make an real cooling unitwith some couple peltiers for an low price which can working. And what i see here on youtube i admit i see a lot of technical units people made ands looks very intresting but, making an coolbox with an peltier element? Sorry.. i onley need for that my water cooled unit to drop into some cooling box, why should i made from that an video.. You now if you buy some peltier unit on one side an big cooling fan and on the other side from the peltier element also some fan, you only get it warmer into the room, not colder, because somebody is recording and use camera and some extra light to put all of this creature for example here in an movie... LOL

Simply put, He has the hot air going know where . Making the little unit work harder .( NOT TO MENTION THE TERRIBLE HOOKUPS.😟 ) THE heat blows out directly on unit .. wiring inside box condensation build metal in water , switch should be sealed inside, or screws not sealed around chip. After awhile with the small constant heat flexing losing up just so little, DRIP DRIP DRIP ... PEOPLE WHEN EVER APLLYING PASTE MAKE SURE YOUR YOU TRY NOT USING YOUR OILY FINGERS ON CHIP n PASTE and plastering the chip instead of a even layer leaves gaps between chip and paste , wich can lead to uneven drying AKA FRY CHIP .. Start with tec 127xxx cheapest chips before you go fukup with a TEC1- 24108 or 12730 350 watt chip ..

You are too "math" dude , just said this is fake 😁

"work a lot".... Do you mean it good for carrying or for cooling efficiency ? Would you give more idea ? Please. ^_^

Waraporn Pan it helps the coolness spread from the peltier to the air

what is that?

Mihad Hossain 👍 *yes well said. This become more efficient with one more heat sinker. You are technically strong.*

I thought this also, but would it ice up and make the fan useless?

Yeah you can see that he is dumb

The idea to use heat sink on the cool side is not wrong. I don't know why people are blasting him for it. A heat sink can sink the cold temperature from the cool side of the thermoelectric cooler into the heat sink. And since a heat sink has more surface area it can dissipate the colder temperature to the air more efficiently than 1 fan with the surface area of a single thermoelectric cooler. So a single same or half the size heat sink from the hot side would put the temperature differential to be moved up so the hot side would heat up a lot more than what was shown here and the cool side will also rise above the 10 degree celcius easily but it can cool a larger volume of space and you can actually feel the difference in temperature much more easily and at a faster rate. As a mini AC this design has many flaws and requires abit more tuning but the main idea is great. Because water can absorb a lot of heat for a longer period of time so you could have a cooling loop for the water to increase the efficiency. The power consumption is proportional the the fans added to the system to make it more efficient and each fans do no consume that much power.... The cooling loop for the water could be powered by a pump or use a simple physics trick, it all depends on how you want to do the water cooling loop. And the pump you should use also draws about the same amount of energy as 1 or 2 fans depending on the specifications.

Nah, you're saying it wrong. The fan at the top of the container keeps the water inside the container cool, so the heat coming from the peltier module would be dissipated through the holes, hence the water won't heat up as much as you think 🤷

@@jhebertdelacruz5437 😂😂

​@@narendra848 sir how do i attact petlier to a table fan

@@coolmonkey5269 peltier module can only be effective when you able to isolate hot and cold side with their respective surrounding..... With table fan is is very difficult.... Instead of table fan you can go for small blower

@@narendra848 shud i add 2water radiators. 1 for hot side. for cooling side i use copper pipes that will be placed near blower air intake. cold water will run inside soft copper pipes. air blowing through it will come as cool air like AC. i will keep it on table and sit close to it.

Good comment. I was thinking of having this unit placed on the water tank of a boat. Then you have warm water which is preferable for showering and cooking. The heat would stay in the water and in that compartment.

Peltier devices are far from 100% efficient. He is creating far more heat energy on the "exhaust" side than he's expelling on the "output" side. Thus, there will be a net heating of the room once you step a couple of feet away from it.

Your genious

Or dont try to cool the bucket water. Let it get warm, empty it and put cool water in in it. This way the heat will never enter back into the room.

Coolant does not displace heat as fast as water. The only reason you would want to use it is if you wanted to keep the fluid from freezing. Then you would not need this AC unit, right?

pp0ppoö

Great idea

Yes! Great for using in tiny house off grid shower!!!....or wash dishes or clothes.....thank you for mentioning. Literally....you could probably insulate the hot water and use it like a hot water heater! Love this!

What if you are outside and you want fresh air directly to your face? Yeah its ineficient...but who cares anyway?

@Vilas Tamhane exactly

@Vilas Tamhane this wont work becoz he is just pumping heat from one side of the room to another ..... its in the same room so the water bucket will radiate heat back into the room !!! what he should've done is insolate the bucket so the heat will be trapped in the water and cant go back to the room !! instead he is moving the heat back from the water to the room with that fan on the bucket lid !!

Some folks just don't understand physics. Heat is heat and all this does is transfers the heat from one fan to another. If the unit was mounted outside the room you want to cool in the great outdoors and the cool air piped in then it would work.

i think its meant to sit on a desk not cool a whole room down

Somebody reply this question?

You mean to say that the HOT portion should be inside the inner heatsink and the COLD side of the peltier is with heatsink with fan? You think it is much better than the cold on the ist heatsink and the HOT side on the heatsink with fan? Pls confirm. Also, can you put insulation materials ,like thermal insulating materials ,the one with foam and foil inside the cooler for heat dissipation? Many thanks in advance

@@Bloodstorm777 Extremely sorry for late reply. Actually you don't need any heat sink at cooler side to further cooling it down except attaching a high power or larger cooling fan. The only strategy you should take to cool down the hot side with a good heat sink or for better result heat sink + cold water. Remember if you can cool more hot side of the module you will get better output from the cold side. The another important thing is the distance between cold and hot side of the peltier module, which is so close that you must properly separated and sealed with a thermal pad or you can use any good thermal material like Styrofoam so that heat cannot exchange from either side. For quicker result you may add some ice cubes in water or use bigger container because the water temperature will rise shortly after you start up the module. Thanks.

@@asmziauddinahmed1764 good day. Thank you for taking ur time to answer. I have just put an aluminum block in between the cold and hot side of the peltier ,the cold side at the bottom while the hot side at the top with heatsink and server fan attach. I have tested it and it works great. By th way, i attached my diy peltier module on my old aircooler and as everyone knows, it cannot fully cool the whole room compared with airconditioner but it can make the air coming from it much cooler directed at you unlike using an electric fan. Tested it and was able to get a registration from my digital thrrmometer of from room temp of 31 C, it goes down to 12 C in ten minutes interval. Really like it and will try to make a much larger one using old or discarded one tub washer or old cooler.... thanks for your info cos it helps me with my project...kudos

@@Bloodstorm777 I am very much glad to hear that you have successfully completed the module and it works great. Hope you will satisfy with it's performance. Enjoy!!!

Thermal paste Easily available on amazon

nice question.......

haa re kyu ki cooling side to bahar hai na to cooler kaise ho sakta hai ye to heater hi huana...

USING 10 amp power supply

Peltier module will work at its max efficiency but it's still Resource wasting
