- Hey Guys! This is Vishal here and today in this video of mine I am going to make a Powerful Air Conditioner Using Peltier Module And CPU Fan.
This Homemade Portable AC is Very Powerful, It is easy to make. You can also call it a homemade air cooler. This homemade air conditioner works on a 12V 6A power supply, here you can also use 12V adapters and 12V batteries to make it portable. You can use this homemade powerful AC in a car, room, office.
Here I am using 12 volt Peltier module to make this Homemade Air Conditioner. I made it out of PVC Pipe And It's Looking Very Premium.

this is amazing i have make same to same thank you
lmao its dumping the heat out the back. Basically it does nothing. Actually since peltiers are inifissint, its heating the room more than its cooling.
@Yousef Cook And Tech Vlogs I... dont think you understand how thermodynamics works
Agar sunboard sheet na mile to kya kare
@Yousef Cook And Tech Vlogs ah right my bad. Well since the fan is weak, you would have to keep it close to the window, and a single peltier isnt gonna do anything to a room.
@@ameerkhan3257 hey ameer, if we plug a peltier in a 100litre desert water cooler tub...will it work ??
You cannot cool any space with it - unless you stick the hot back-end out a window. In fact, there will be a net gain in room temperature if you don't. This is because all the electrical power it uses will be converted to heat, and go into the room air. He left that out.
Yahh right 👍👍
Thank you for using your brain. People should learn basic thermodynamics
It depends upon what's the heat generated in a peltier? If we take second law of thermodynamics the heat generated cant be more than the cooling generated (primary work done). I can explain it thus if a refrigerator is left in a (small) room with its doors open, it WILL cool the room (more than a peltier)as the heat generated will be smaller visavis the cooling generated. I dont know how true its for the peltier. Will the cooling be more??? or is it the heat???
EDIT1: The refrigerator behaves as a heat pump, so the cooling will be for a short time but eventually it will end up heating the room😣
Say a Television consumes 1Kw power. The primary work done is the movie displayed. Since NO POWER IS DESTROYED 1.000KW is returned back to the nature. (Power is not created or destroyed). But how??? No one knows. There will be heat generated but its very low (losses typically will be 2% or 20W)
it could possibly work well for a small grow tent if you having temp issues which is what im lookin at it for
@@jonathanellmann4577 I reckon the power consumption will be way too high. Donot increase the voltage (current) beyond a limit.
Bruh, this is the equivalent of leaving your fridge open and expecting it to cool your house... to cool your house you must displace heat energy to OUTSIDE your house. Thats why your ac units have radiators outside the building. What youve made is essentially a 50w heater... astounding.
And even at heating its kinda inefficient, a normal wire with electricity going trough would be the best. This is just... Made to blow less hot air at you but then make more heat in the process...
What if you made it bigger and square and put it in your window?
@@tigeroswald777 if you isolated the hot side outside your house, yeah that would work. Still very inefficient though. He uses a TEC plate which is good for compactness but not efficiency. Your home AC unit is many percent more electrically efficient than one of these.
brilliantly obsurd. the 5kw version might help a little if someone else pays for it. 75.0f in -> 74.6f out it's much help over a straight fan
It’s multipurpose bro 😛
This gives me hope that this time, my Perpetual Motion Machine will work.
LOL

Ehehe
I have just now competed watching exhibit "A" and reading this observation report. After reading all contents, it has resulted in me pooping my pants. FANTASTICUL!!!!!!🗣️🙂🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️🗣️💩💯💪🤣😂🤣😂🤣😂🤣💥...............................👏👏👏👏👏👏👏. 👏. 👏. 👏. 👏.
This has to be the most savage comment 🤣😂
One of the best non-functional designs I've seen in youtube
Put a lens or a heat absorbing plate where the 🌞 shines on it, connected to that peltier convertor, then it might work, but the built up of it's freeze effect will be nullified with that fan sucking it out of the tube.
Better have the fan blowing inwards, the cooled air would get out through those drilled holes, making it effectively. Place it high enough, as cool air falls down, cooling off the warm air layers in the room gradually.
But nice watching this creativity taking shape. Keep brainstorming!
*Hi, I'm from Vietnam and I do the same job as you, I wish you good health and success, nice to meet you, look forward to learning more, Thank you*
This works great for making a mini AC for a cat/dog house. Made one for my cat house. 👍
ok to everyone commenting the obvious that this wont work your kinda right
but if your aims to keep YOU cool this would work somewhat sure its gonna slowly raise the room tempreture but not by much at all considering its like 50w of heating which aint much
but if it can drop the air its blowing on YOU by say 5 degrees its enough to be some comfort
so few issues I can see with this:
1. its only for direct use as you are venting the hot side in same area
2. its built in a way that is hard to take apart to fix anything i feel if you would have used 4 long bolts instead and put everything togather using that it would be easier to fix later.
3. the way its built you will build up condensation from the cool side from the air and it has nowhere to drain maybe drill a hold and put small drip tray. (I cant imagine much but enough will ruin the device.)
other then that good build friend.
That's how my tiny fridge works, nice.
For those who talk about hot air out, please have a flexible conduit run till the window exit from the hot side fan and have a air tight seal there. You cant expect a AC cooling from a device that consumes power of 20 times less that that and the heat load will always be more than this device's capacity. This can be a good cooler not a AC.
that wont work properly because of the air flow of the fan is side ways not backward, you need some air in and some air out for it to work
It's not that it consumes "20 times less power". It's the fact that are inefficient
Look, all you idiots fail to see the basics, put the Whole cooler outside, vent the cool air inside. But dont use a crappy peltier, use a compressor.
@@crf80fdarkdays can someone explain why it's inefficient,i never quite understood it
@@nopenope8364 It's inefficient because most of the electricity used just gets converted into heat and even if it were 100% efficient at converting energy into cold it would still wouldn't be that great compared to any other cooling solution because, fans by themselves are very low energy but provide a large cooling effect, even more so with the addition of adding humidity in dry environments and heat pumps like your A/C have a coefficient aka "Coefficient of Performance" which gives them an effective ~300% efficiency.
To put it as simply as possible, if you had a 100% efficient peltier using 1kW vs a typical roughly 1kW window A/C unit, the window unit would give you 3x as much cooling for the same power, since that isn't the case and a peltier can be as low as 10-20% that makes it so much worse...
Imagine trying to use a whole home central heat pump's worth of power just to cool a single room.
The thermal optical properties of the thermal materials will allow a modified structure to percolate
The navical structure of the heat distribution and therefore intensify the cooling process for which the cooling system was designed.
Just saying!
Just getting into this and it’s fascinating. I am hearing that this system is inefficient right now in comparison to AC and compressors but it’s size and quietness as well as better production/R&D/manufacturing can help reduce the major gap (not saying it will ever come close to the efficiency of cooler tech today) and be useful in very specific applications. For example I am using it now to water cool my bed and office chair. My exhaust is being routed to the next room over and I have sealed the door where the two rooms meet. Since I am only running a couple oz of water through the loop and my body isn’t the size of a room or get as hot as a CPU cooler, I think it works awesome ! My room has a higher end gaming laptop and the new Xbox as well as a 55 OLED tv and dual 32inch 4k monitors with 1000nit hdr peak brightness. So everything turned on can make the room quite warm. I have my living room connected via another door and above it a circulation vent of which I have placed 3x140mm fans to help removed the warm air. In an application where you are choosing to dissipate and redistribute heat elsewhere, it works wonders. So long as your body contact is cool and your ambient area temp does not suffer (just your room), you are getting results. Just need to improve the energy waste and we are golden.
if it ever worked......we'd be having commercial ones everywhere....peltier is a comic book.
Would have been cheaper to just get AC at this point.
wait what. sounds intttttttttttttteresting, can u exlain detail how ytto water cool bed
Perfekt! Für den Sommer eine prima Heizung 😂
i will put it to my little bag. Does it work in it?
Man, always those comments claiming fans don't cool citing fancy thermodynamics. WRONG, FANS DO COOL. Cooling doesn't have to be changing temperature. If I feel cooler, it cools, period. Fans move away the warm air contacting our skin and replace it with cooler air. Your sweat will also evaporate quicker with moving air.
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?
Me, as a professional would say that it would be too expensive to make a cooling system for peltier's hot side for the cold side to reach -20d . You better buy 1 ton air conditioner thats cheap then peltier
Peltier is for vibration free small portable fridge but those are not a good choice to cool a room unless it is very small like a 1 seater car which has limited space and has to be lightweight
This things waste a lot of power. They're too inefficient sadly
i made one like this a while ago and keep improving it .it runs on 12v 3amp it cools my 2 bed flat nicely
TECs have an CoP of only 0.5-0.6 running as coolers, so you cool your entire flat with .6*36W or ~18W? The computer you're watching this video on puts out more energy than that cooler is capable of cooling. Do you live in a flat for ants?
Brother can I use 12v, 1A supply for this
I am very much interested to build it. Can you send me a making process video of your ac. I also want to make it by my own for my room. Please reply sir 🙏 😊
With the single Peltier module, how much needed for a small room to cool, at least you should put a temp indicator to show its performance.
Looks like most people already know that this will heat up the room. I think this is better used as a fan that blows cold air. Other fans just blow the air that's at the temperature of the air around you.
You're saying it like a refrigerator bakes things instead of chilling them
The cold side absorbs heat while the heat produced at the hot side is dissipated using the aluminum heat sink + fan
can this project cool down a single person tent .
I will keep out the hotter side out.
It will make ur room hot like hell in 10 minutes
have you made any documentation for analysis of this project, like temperature relations
????
Sir 12 vol 6 amp paltiar 4 pis chalne k liye kitna amp powar supply lagaga sir.
Prevents break ins. This I needed.
Yea this definitely worked thnx so much
For all those who fascinating of this idea have a look.
In terms of COP
Peltier based ref has 100% efficiency i.e both COP (or Efficiency here) is 1. But any random AC has as average COP of 3 and goes higher in inverters AC so basically it's on an average 3times costlier.
Also here in this demo heat sink in the same space so over a time it's zero heat removal or no cooling effect just a fan.
idealy you would have an open window so you get fresh air aswell and the hot air can get outside
🤣🤣🤣 it's just a fan..
Uska part kaha milega ❤
One heck of an instrumental 🤯
Has your refrigerator cooled your room anytime?
Evaporative Cooling is different. Direct cooling as in video adding moisture to the air. Indirect cooling from industry leaders with Wet bulb temperature. Dew-point regenerative indirect evaporative cooling from Maisotsenko Cycle.
Did you Checked Temp of the hot side & Temp of the Cold Side. ?
You have to stick in a Window...to remove the heat outside..and in winter to reverse the project
Bhaiya kya ise solar panel PR chala sakte hai kya...
Nice work bro👍👍👍🤝🤝🤝
does it cool or heat more?
It looks nice, but... If we know the basic law of thermodynamics, then it is clear that as much cold energy as we create, the same amount of heat is also released. So, cold air is created in the pipe, but warm air is released on the external fan and cooler... It is for this reason that air conditioners have an external unit that releases heat outside the space we are cooling... This is only ok for directed cooling, but still in the same amount of heat is released in the same room...
How cool was the air?
it cannot cool any space with it, but it is an air cooler, im not saying its bad, its amazing, im just saying its just an air cooler.
It won't cool down a room instead it will repeat the same process like when it produce some cool air the heat air is also produced from the peltier. So if you want some good result make a tube from back side of the peltier to a cooling fan and place it outside the window.This can be a personal air cooler but not to cool down an entire room
We can fit this system in ac?
Displace the heat with two Aluminum Water Cooling blocks, a radiator with a fan and a second Peltier, a sump pump, and a water bath using a mason jar as the reservoir. If hooked up correctly you should be able to reduce the exhausting heat to or near ambient temperature but whatever you do, don't boil your water. The returning water to the jar should pass through a copper pipe and spray so it will cool a little more. You can add ice and water to the mason jar to give the second Peltierit a jump start. Similar in principle to a swamp cooler except you contain the water. In theory, the exhausting heat will be cooler through the radiator.
At that point, you might as well buy a portable or window AC.
Will the white thing make power if you put ice on it
Good job my friend 👍❤️🙏🙏
Thank You very much!
awesome! I have a 100W solar panel, 17V 6 amp that's sitting idle. This is perfect for people selling items outside (street vendors, outdoor flea markets, etc.) Thanks for the video :=)
What is that device on which hot and cool is being written?
how cool does it gets?
Admittedly this isn't very efficient and not strong at ALL, but it is surprisingly simple to make and with a small-scale solar rig, it can off-set the efficiency electrical issue and be 100% renewable. Peltiers cooled properly last 15-25 years normally, which is longer than many air conditioner units' condensors. Although small and using more power for large spaces, peltiers are very very good and very very efficient for rapidly cooling small spaces. Try making a freezer-in-a-freezer box or a matryoska freezer with them and you can get cryogenic temperatures slowly!
So you say this peltier device might be good for freezing the air in a small container? I build ice chest air conditioners. It has 3 radiators circulating ice water. Has air tubes that guide the radiator cooled intake air to the bottom where it perculates up through a bed of ice then exits the top through another radiator and fan. I'm curious if a couple of peltiers might help freeze the air flow in the cooler and keep ice from melting longer
No bakwas... Fully detailed crisp video i have seen recently. Well made project, well presented video. Well done. 10/10
whats that hot and cool written thing ?
please pin it brother.. the work is great.. thanks for the knowledge. greetings from Indonesia💝🇮🇩🇮🇩
How cold air comes? Normal air only will come.
Does this comply and in the event it causes a fire will insurance companies pay for total loss of eg house.
The hot side isn’t very well isolated from the cold side. If ambient temperature is high it’s going to be difficult to achieve the temperature delta to be effective especially with 5a
How much area it can cool?
Can I use 12v ,1A supply
2.4mil viewers of this channel are hot. GreAt video. Really helps break the steriotype than Indians(dot, not feather) are good at engineering.
To answer your product for everybody here I have a question:
Where is going the hot air flowing out from the peltier hot side?
success for "Pro Know"
Heat sink is of 4mm or 6mm please tell
I can use this in an indoor garden tent!!:)
Will it actually work
@@prantikdevil9186Yea, it would prevent their plants from getting so hot due to sunlight
Simple as that ;)
how this could be efficient if the hot air will come out on the other side ?
This was supposed to be a school project and i don't know how but when i saw this video i immediately clicked on it and i got an A+ thanks dude
👍 😂 🤣 🤭 😆
I think the radiator on the cooling side should be bigger and you should force the airflow thru it with a hood for maximum cooling
It's a 75w peltier. The cooling is going to be minimal. That heatsink likely is already overkill. At best the heatsink would need to transfer 7.5W of heat on the cold side.
how much does it Cool the air? I mean what's the Air Temperature?
That will destroy your Peltier unit as you will have hot spots it must be fixed to a perfectly flat surface, not ridges
Bro how much time we use it continues
Unfortunately no. If you understood basic thermodynamics you would know that this type of setup (in this configuration at least) cant do anything apart from increase your energy bill. The reason this doesn’t work comes in with the way the heat exchange is set up. As we know, Peltier modules or Thermo electric devices, produce a cooling and heating effect on both sides. Which side gets hot and which side gets cool depends on the direction of the current AKA electron flow. Taking this into consideration, the whole reason AC works is because of the way temperature works. Temperature in itself is defined by the average of kinetic energies across all particles in a given amount of matter. So when we cool a room using AC what we are really doing is removing that kinetic energy from the matter present in the room (i.e. molecules in the air) and 'placing' it elsewhere, we do this using methods of thermal exchange. In this case heatsinks and rotating fans. So for AC (in simple terms) we need two main things. Something that provides a thermal flux, that is a flow in thermal energy. AND something to make the heat exchanges efficient so that we may move this heat elsewhere i.e. OUTSIDE of the room we are trying to cool. With a system like this, our component producing the thermal 'flux' is the Peltier module but in a more common device might be a compressor system. In a compressor system we use a closed loop refrigeration system (this is important) and we alter the pressure that a refrigerant is under. Because of the way the ideal gas law works, when we keep volume fixed (closed system), and pressure is increased (with a compressor for example) temperature must also increase in a fashion that is proportional to the increase in pressure. So, by lowering the pressure in one side of a closed loop, temp of the refrigerant drops and therefore absorbs heat from the surrounding air (via heat exchange methods - heatsinks and fans) and increasing the pressure on the other side, there will be a natural thermal flux between the two sides. The hot side of the AC will warm up as the cool side cools the room, as you may know energy can not be destroyed or created, it can only be moved and change in physical form. Due to this law your set up will not work in this layout. While you don’t use a compressor in your build the same logic applies. Our intention is to move the heat or kinetic energy out of the room but with your design the heat has nowhere to go. On both sides of your Peltier modules you have fans and heatsinks this is correct, but to truly cool the room we must move the heat elsewhere i.e. outdoors so it is not radiated back into the room (which is what happens with your setup). Now, another thing to consider is that no device in this world is 100% efficient so your Peltier modules may be 90% efficient at best and also resistance in wires results in further heat radiation. This means you aren’t even breaking even on your heating vs cooling power. This means as a NET total you will actually heat the room up as you are feeding electricity into a system with nowhere for the heat to go apart from back into the room you are trying to cool.
ps.
Ideal gas law:
Pressure and volume of a given mass of gas at a constant temperature can be given by: P 1 × V 1 = P 2 × V 2
AND If you want to make this design in a way that actually cools the room then simply add a heat removal system. Basically the heatsink for the hot side should have a coolant flowing over it and then the now heated coolant should run to a radiator (with fans for higher efficiency) to a place you don’t mind heating up. This could be another room indoors but any sane person would put this outdoors, it just makes sense. I think a more accessible way to do this would to be to use a AIO liquid cpu cooler. By simply cutting the tubes that run from the radiator to the cpu block and adding a few more meters of tubing (and topping up the coolant after resealing the tubes) this i think would work pretty well as a heat exchange method. Another thing to note is that for this to be truly efficient, you should be using much finer heatsinks. Basically you want as much surface area to volume ratio to maximise heat transfer from the air to the cold side of the Peltier. I mean you could also probably use a cpu AIO cooler for this aswell.
pps.
Hope this makes sense! Don’t be fooled by these awfully seductive physics scams!
How much cooling does this device offer and what is the power consumption?
Also wht is the cost of the unit.? Can this be used as a roofing material for buildings ?
My old san ace fan will be so usefull
able to work how long?
Can do a temperature measurement of the air entering and exiting the aircond?
Why not use 6 peltier modules only sandwiched between three cooling blocks, the middle block which is cooled is pumped to a radiator. Use Coolant instead of water. Run the peltier 12706 at lower voltage.
Veer 12076 model nhi mil rehya.... 12706 hai.... wo theek hai na pls suggest
I think you are behind the fan that you say the fan is cold... in fact the one that comes out is hot because there is a heatsink... and the side of the fan that is the new unit is cold
Good job uncle
anyone did it ? what is the temperature of the cold air ?
Any alternative power supply cheaper
Alibaba, why you keep inside heat sink? What you get cooled, that much heat must be disipated
good to see you video video is very good
Where will the hot air goes?
Blowing cold air on the front, hot air on the back?
I am not sure if it is a conditioner in the summer.
If you want hot air, turn the heat sinks to other side?
12 v 2 amp adaptor can I use
No, You have use 12v, 5amp adaptor
@@proknow can u suggest cheaper adaptor
@@proknowcan you tell me the specifics of the pvc pipe?
I made tabletop ac recently with separate heat dissipation unit
what is a sunboard?
Power consumption .... How much... In watts?
too much, i've burned out a computer power supply running one before. they range in wattage depending on size. this device is a waste of energy anyway, the working principle of an air conditioner is it functions like a pump by sucking up thermal energy and transferring it elsewhere, which is always OUTSIDE the area you are trying to cool. this thing will only succeed in heating the room MORE and wasting a bunch of energy in the process.
small holes near peltier will suck room air in and move through cold heat sink and gets cool... good... but warm room air also sucks in through large holes near the fan... that's bad... what is the purpose of those large holes near fan ?
This project design is good at 50% and it has 50% odds... This 50% idea can be converted into 100% sucess... Perfectly divide hot area and cold area... Thermal insulation... Avoid all holes... Position the device's half area.. (Cold area) inside the room and the other half (hot area) to the outside of wall. Seal perfectly the surrounding area... Like an ac compatible room. And to the end add a thermosatic cutoff to the peltier... So it can add life to the peltier module...i think 2 or 4 pipe units maybe needed to cool a 12x12x12 room...properly..
Is it possible that you can make 1 for me I am bad in electronics 😀ready to bear the cost👍
if I had to connect it to the 12v of my car via a cigarette lighter, does the peltier cell cool?
Very cool - would like to see temp differences? I have one with a big heat sink and fans on it and it dissipates any hot air quite well - just wondering how much cool air it's putting out =
Read the second comment, wont work as it is, but if you was to try cool a box or something that would
Will it work in a one man tent
How long strong
All over design is good, but you make holes near the outlet fan it's totally wrost. Only you have to make holes to the cold side of heatsink soo simply air can pass through heatsink and air get colder...
The wrench 👍
So what temperature... I understand the wind blow but....... Temperature test? Who know what level of cold right...
The dude putting thermal paste on both sides. What an inefficient sandwich 😂
a great thing for my gaming pc
this would work great for a lot smaller things, like cooling insuline during transport, or precooling the air that goes into a computer, too small for a room though
use dry ice or ice packs for the insulin and precooling pc air? why though? unless you live in some insanley hot arid country normal room temp ambient air is fine we dont care if the pc is "cold" we only care if its below 2 tempreture zones 1 the tempreture at which the solder and cpu and components break down at and 2 the thermal throttling tempreture of the pc
for most things as long as your pc is below 70c thats fine below 40 and your golden but as long as your not thermal throttling at load it doesent matter that much
although in fairness the insulin thing kinda exists car DC cooler boxes and bags use peltiers inside them to stay cool they have the peltier sandwiched between 2 heatsinks with a barrier seperating them the hot side fan blows ambient air over to remove heat from the hot side and vent it to atmosphere and the cool sode takes internal air and cools it down further and re circulates it inside the bag
