- This is a new and efficient method of making peltier air conditioner by using water cooled hot side system. Here tec 12715 peltier module is used.
Water is used to cool down the hot side of peltier module. Inside bucket a heat sink is attached to the hot side of peltier module and its cools down by using water. A top mounted fan is used to cool down water inside bucket.

Is it me or is this guy just making an interesting water heater
I used one of these things to make my dogs water bowl always have cold water. I live in an RV and cold water is so nice in this Florida heat. His bowl has a steady ice cube in the center 24/7 now.
That's cool(no pun intended)
u reversed the sides
Good idea! most people do not realize the capability of evaporative cooling, which you are clearly using to keep the water at ambient temperatures, The only downside is that it creates humidity in the air and if the air is at high humidity it will heat up a bit, but the upside to a peltier is that you only need a difference in temperature from ambient in order to cool!
Thats ITS so simple..nice ide bro 👍
Thanks for your video !!!
I like it because you show all temps
This is a good idea to use water to cool down hot side. To have some results, use at least 4 peltier modules, fix a heat sinks on cold side too and let cold air be blown from the heat sink on the cold side towards to room. You must fix the whole assembly on a Window to make sure that hot side is kept outside the room.
You are so talented dude..keep up the good work...subbed👍👍👍🍻
Great idea all I have to do now is to figure out how to put exhaust and intake on hot side vents like a portable ac but must always be near a window thanks
This is pretty smart
Thanks for sharing. I like the water cooling part a lot, because it seems less cumbersome than using water cooling tubes and a pump. I gather that you are getting an evaporative cooling effect with the top fan. I would be curious how long it would take to cool a 10x10x7 room on a 100 degree Fahrenheit day. I would also be curious if you started with ice cubes in the water whether this would bring the cold out stronger and quicker and by how much. I would also be curious if you insulated the chamber and had tubes running out of the room from the chamber, whether having the water in the room would cool faster (because of the evaporative principle working for you) or whether having the heated water not transferring to the room but going outside would cool faster. I would guess that a drier room might affect the results (help the evaporative principle).
Very nice
looks sick on my pc! :)
Gracias,lo voy a poner en un Inverter casero,con esto solucionó el sobrecalentamiento de los circuitos
NICE ONE
I USE IT TO MY CUMPUTER WAS NICE
cool thanks
superb
hey bro what glue did you use to attach the heat sink into the Tupperware ?? Thanks
wow, nice video!! imagine using 4 peltier the same way in a bucket 2x bigger with 4 fans intake and exhaust. i think maybe good for a medium room cooler?
The big thing here that people are not thinking about when prototyping or building these little Air conditioners is that they need to get that heat out of the room. That is how your house AC works. It basically pumps the heat to the outside air with refrigerant as the heat conductor. To use Peltier units you would have to figure out how you would get the heat to the outside air. With this water method being used maybe he could have the water pumped to a radiator outside or possibly to a pond big enough to help keep the water in the tank cool enough. I do know that our coal fire power plant here uses a method similar with their ponds to help cool their water that is used. Another idea would be if the water was ran in pipe deep underground to help transfer the heat to that. I'm not sure how well or efficient all these ideas are but it should be considered.
Do you put the hot side facing the water or do you put the cold side to the water ? Thank you
The water will get warmer the way he installed the heat sink against the hot side of the peltier. Also you can not cool an entire room with just one peltier element.
Great idea. But on the hot side, once the water gets hot, the cold side would lose its effectiveness too.
He installed it wrong side the hotter side is inner in water while the cooling side is outward. But the idea is the best anyhow.
Pl. mujhe batao ki is prakar ke projector me 4 peltier lagane se room cool hoga ki nahi please mujhe batane ka kashta kare .
You will need at least 8-16 TEC modules in this configuration. Cold side goes to the aluminum water block with water pump going to an external radiator with fan to blow cold air off of the water radiator. Hot side gets large heatsink and air moving fan to cool heated side. With a partition to separate the cold side from the hot side. Partition goes in window frame with hot side outside and cold side and water radiator on the inside. That is how a window unit is designed.
Good job bro
You made it easy
I like your idea
#cyberlink
If we use as air conditioner, since after some times temperature gets down. Upto what hours we should run this?
In your project which is the hot side of peltier nice tutorial gud day from philippines
you can use the two peltiar of 706 which can more efficiant then one 715
Not too bad of an idea for more direct cooling of the hot side heat sink.
How do you think a mixture of ethylene glycol (automotive coolant) and water would perform versus just water?
you should give the product buying link in description
Konsa paste use kiye ho
You should give water circulation for the peltier module heat side. You will need aluminium waterblock cooler to control the heat and a summarising pump for water circulation.
did you get your power through a battery?
Will work a LOT better if you put a heatsink on the outside as well.
"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
Can you suggest required volts and Ampere to run peltier module
Use what glue stick metal to plastic?
What was the temp of air coming on cold side fan
tec 12715 what glue is used to bond?
wow. cool wind from one side and hour later = warm wind from the hot water *lol*
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 🤷
radiator with fan cooling for the hot side of the peltier will be a compact solution.
My god, I was tired watching videos of people just joining 2 heatsinks per module.
This for sure, will work. And also requires another heatsink to cool air, thermocouples to avoid heated water above 50C.
This should be more of air cooler than water cooler.
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"
U put peltier heat side in to the water. How it exit cool air.
Does the plastic gets melt by the heat of the heat sink ?!?!
Just the different temperatures of top and bottom of river or ocean you and imagine how much power it can generate with just 3 degree different and that much current man I would be rich
How cold does it get?
Bro hot side to cool Karne ke liye watar hi use kar lete watar me fan lgane see to room heat hoga
Try reverse cool the water with cool side attach a heat sink replace with a bigger fan to blow cool air out and try to put the hot side with heat sink and fan outside the room maybe a window see what happens also try to avoid installing the wiring inside where the water is and I think it’s better to use an insulated box for better cooling
Vai glue kon sa dia?
You should use a heat sink on the cool side
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.
If you flip the module, would it freeze the water?
If I use an evaporator and fan behind it ... like the one used in air conditioners ... and pass water chilleded by pletiers inside the evaporator ... where the temperature of this water reaches -20 degrees Celsius after adding an antifreeze to the water ... Will I get enough coolness to cool a room and how many pletiers do I need to do that?
Somebody reply this question?
i think you can also make distilled water from your 3 vent holes too
pp0ppoö
Great idea
Heat should be sent out of the room by tubes. Otherwise, room heats up instead of cooling. .
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
What work for upper fan
Why u didn't use a heatsink on the cool side? It would've prevented formation of water and thus increased the performance of this build
I don't know much about modules, but -6*c is not as cold as previous clips I have watched averaging between -16*c to -17*c. Mostly from TEC1 modules. It can reach that temperature in just seconds. Not 20 or so minutes.
Kya yha room ko cool kar sakta h
Or we have to stopped it after some time?
Somebody correct me if I'm wrong. Assume a 2x2x2 metres room (bit less than 6x6x6 foot), that's 8m^3 or about 9.8kg of air. Assume fans that push 3 m^3 of air / minute (around 100 cubic feet / minute). That's 0.05 m^3/s. Assume we use a *huge* 20x20x10 cm heat sink on the cool side and ignore the hot one. That's 0.004 m^3. This heat sink has about 0.08s to transfer heat before the air exchange around it (simplified). Let's assume a 100W Peltier module and half of it is used for cooling. For one volume of that heat sink with this fans the module can transfer 50W * 0.08s = 4 J = 0.04 kJ of heat. If we were to cool the air by 20 degrees we'd need: air mass * air capacity * temperature delta = 9.8 * 0.7 * 20 = that's 137.20 kJ. Our hypothetical Peltier AC would lower the whole room temperature by 0.005 degrees each 2m40s in conditions of perfect isolation. So about 0.11 degree each hour. It would take it a bit over 9 hours to lower the temperature by one degree. The air blown out of this thing would still be hot as in: no difference to touch. And this guy's unit is way less capable than what we're talking, his isolation is non existent and the temperature measurements he ever shows are of the Peltier module itself, not of the air. It would be actually more effective to cool that room with a bucket of ice.
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 😁
peltier ko kis paste se joda h???
Hi bro , 12v 5amph ki adapter mein peltier ka cooling side thora der bad hot ho jata hain. Iska solution kiya hain. Pls comments
USING 10 amp power supply
what glue did you use in peltier to heatsink???
Thermal paste
Easily available on amazon
you have to add small heat sink to cold side for convection and use a larget water bucket for hoter side, in this way it will work better and you will required to change water in few hours. this small water container will get heated up in few minutes and heats up your room, also increases humidity.
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.
Sir where from you by the heatsink and how much Rs
Some of the videos i watch related to this uses car coolant
You can also place a heatsink on the cold side of the module and place a bigger fan to produce that cool air on your room.
Nope it will not work mahina lang magpalamig ang isang peltier module sa isang room halos wala pa ngang epekto
I want to ask a question ...
If the cooling capacity of one pletier is about 50 watts ( Qmax = 50 watts), which is equivalent to 170 BTU
We need about 70 pletier to get 12000 BTU, (12000 BTU = 1 Ton refrigeration) which is the capacity of the air conditioner required to cool a normal room ...so , How efficient is this device in order to cool a room
Is it wrong side?
Why dont take the cool side to inside the box?
And u will get cool air from exhaust
What is rating of power supply required. Like 12 volt DC, what Amperes it should be
If u are using 12706 peltier, a 12v 6A smps is enough .. for 12715 peltier, 12V 15A/12v 30A .
A normal 12 volt battery will last for how much time
Can it cool 100sqft place
and a 24 hour chageing time haha
What is the size of the seatsink?
Hello, super great job bro, but one thing, i know that you're showing us the sides of the fans, but plz and of course no offence to you, yeah plz say and make sure about this thing, (that where to put which side of the fans on it's place) cause many people don't know which side blow the air and which side suck the air, and plz don't take it offensively to your magnificent work, and thank you for sharing this video with us, bye for now.
Your genious
How longs it works continuously
Bhai tum cooler bna rhe ho ya water heater
nice question.......
haa re kyu ki cooling side to bahar hai na to cooler kaise ho sakta hai ye to heater hi huana...
What do you think would happen if I put car radiator coolant in the bucket instead?
Peltier module will work at its max efficiency but it's still Resource wasting
Arey bhai Peltier Heat Sink kaa size kyaa hai? Ye batana chaye thaaa.
So dear the hot side of peltier must be cooled down in everytime when we need to bring down the temperature of the peltier cool side?
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
Can we cooled the water ....
That would work better if you put a smaller heatsink on the cold side also
if you're going to absorb heat from the room only to reject it back into the same room. average delta temp of the room is still going to be 0.
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.
👍👍👍👍❤❤❤
If you make water cold and make air vent on top of the cover will get cool air if u make water hot will not get cool air from out. And oneside of peltier that's hot should put another heatsink with fan and on cooler side also heatsink too touching water.
Bhaijan ap ne silicon use Kia ha pasting k leye?
But you are missing the most important data. How much more efficient is this method vs non-water method (with the same device). We want to see the temperatures of each method.
What is the cold side
What size is the heat
Room thanda karna tha, room se jyada to paani thanda hai.
Also you should use a heat sink on the cool side
good idea but make it more practical which can be use in real life
btw you can use coolant also in place of water
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?
Add a thermostat to cut of the cooler ........ so that there will be no frost at the cold side
How is it working good? This is a very inefficient way to cool a room.
From which country are you ?
Hey..
I have some queries, how can I contact you?
The three exhaust holes from the bucket should be one hole connecting to a hose to exhaust the heat outside. Theoretically this won't be able to cool anything if you're not removing the heat from the room completely.
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.
Tell me the components needed
n where to get ...
Sir you didn't tell us About that all of a tools names
like where can we Find
Regular AC put heatsink outside the room, but this one is just put together in side the room.
Are peltier lasting long day??Anyone have idea??
Heatsink will rusty in water?
I think most heatsinks are made of aluminum or stainless steel, so nah
