Good video, I see a few issues. 1st of all - no thermal paste. Heat induction to the fins will not be optimum. 2nd issue: No adequate heat dissipation. Maybe try a water cooled heat sink/exchanger. 3rd issue : your temperature probe is kept inside the box. This is wrong. The A/C needs to cool the air outside the box. By placing the temperature sensor inside the box (very close to the heat sink on the cold side) you are displaying internal temperature, and not the AC effect outside the box. Viewers need to see the cooling effect on air outside the box. But keep it up. I liked the idea.
2nd - It need to go outside, otherwise he just creating more heat. Peltier is basically moving hot to one side and cold to the other and while doing it, it also creating a little bit of heat too (energy loss).
And did you noticed that the heat goes into the same room so it acts as heater? And the power supply should be in another room so it will not heat up air in the same room.
Trew Mika Power supply is creating heat, but not as much as just throwing the hot air back into the room from the peltier. It can still cool the room if the PSU is fairly efficient and the heat from the peltier goes outside. And as you said, he is just heating the room, which is dumb.
I did too many experiments last summer and come to this conclusion that peltiers need too much energy and much more to balance the hot and cold side. Tremendous waste to time. So they r in store nowadays.
TEC-12706 cell takes about 4A and you have four, plus 0,9A fan, and you have two. I don't have any calculator with lcd display around me, but should make 17,8A, and you need some more just to be sure. Let's say 20 A power supply. And you have 10A power supply.
One tec 12706 need 12v 7 to 8a. 7×4=28a 12v 0.90a fan. Which are 0.90×2=1.8 almost 2a 4 small fans equal to almost 12 v 1a Tec=28 Two big fan 2 Four small fans 1 Answer is 31a Means you needs almost 12v 35a power supply. To run the project smoothly. 12v 10a which is 1/3 of the real need of power. This video is totally worth less. Matlab Kuch Bhi. Shame on you 😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡😡
Design is good, few changes needed to be done like use of thermal paste, air input to sink need to be improved to increase more contact of input air with heat sink fins. For those who are worried for heat exhaust in same room a pipe can be attached or some other arrangements can be made depending on your placement. Again I am very much impressed with the design. Thanks for the video upload.
This is a great idea, but personally I'd have assembled it in a different order and prepared pieces before gluing them in place. Work smarter not harder.
The problem still arises due to hot & cold issue 80%vs 20%but its nice to see such activity like this lods thanks for sharing sabi ang idea ay nagiging perfect the more we're trying.
its good toy AC, but real working AC ca be made using peltier, 100% possible but would require 56 peltier (12706) surface conduction area approximately 200 square inches , its performance will meet 2 Ton AC. 01 (12706) peltier takes 3.5 amp . 56 will take 196 Amp 56*3.5=196*12v=2352 watts and 200 Watts for blowers, total load 2552 Watts. However thermal insulation is critical point. it will obviously save energy with smart and quite design, no noise, no starting heavy current, no motor induction losses and no wear parts. it will roughly cost 250$
It is real AC ! i think 4 fan and i peltier will not work, and 1 fan and 4 peltier can cool 100sqft space in approx 1.5 hours. u can call it toy ac, but it really works, Higher CFM fan can be deployed but it will suck more, and peltier will not be able to supply more cool air, so lower cfm is good idea ! SO What it can run on solar panels of 100watt
An excellent project. However I noticed 4x 6 amp peltiers (total 24 amp) and the power supply is rated to 10 amp? No thermal paste ? How long can this run before it burns out ? The placing of the temp censor on the plate that is connected directly to the cold plate on the peltier will give an artificially low reading. The heat exhaust is venting in to the same room so room temperature will actually rise due to inefficiency of the peltiers.

Good effort. If you add a diode bridge to the fan's you can simply swap the polarity to the peltier's to reverse the heat flow, therefore a switch could be used to make it reverse cycle. It's also better to use liquid heat exchangers with peltier's as it stops the airconditioner from becoming a heat exchanger itself when it's not powered on, especially good if you plan to fit it in a wall. I did one using liquid CPU coolers with a little radiator in each side. Works from a 250 watt solar panel and keeps the temp down a few degrees with zero running cost.
@@irtzashahanpk My office room is well insulated (R-10), and it takes a few days of heat to start getting hot inside, but with that system always on when the sun shines it keeps it at about 22C, where without it it used to creep up to 30C. The effect is small, but over a long period it makes a fair difference. I get a similar benefit in winter, it adds a few degrees on cold sunny days, not sure how much as I still run extra heating, but it's never freezing when I come in at evenings.
Nice video👍 It is an Air Cooler The temperature is inside to show the temperature that comes out.. It would not make the whole room cold like air conditioner but it keeps you cool when you are hit by it.. respect and understand the project before over reacting😊 Tnx
I am trying to make a version where the hot heat sinks are in a big container of cold water with ice in it... Then if I change out the water regularly it will make the whole room cooler
Good concept but execution could be improved. I also understand building with limited resources but this was a lot of work for 2C delta T. Stacking the modules would improve cold side temp exponentially. Recirculating some cool air across the hot side will also help. Mounting a pulling fan directly over heat sink would also improve cold side discharge temp.
You haven't shown that how much down temp fall. But your work is very nice.. if you help me, I will make it. I hv some question sir.. plz help me by responding. How much total cost of your created ac? What is white board you were using? Is it thermocole? What adhesive you used ? Will this portable AC cool a room of 1000 sqft?? A 10 x 10 feet room?? You used a heatsink with peltier. What I should tell to shopkeeper about the exact heatsinks..? Thanks and regards
I'm new to this Peltier stuff. I have bought an assembled Peltier with one heatsink on each side of the chip and one water block each side and fan. I see a lot of heating and cooling functions. how is this determained if it cools or heats? I need mine to cool the water flowing trough for a Laser Engraver.
I think he used 4 x 6A Peltier with 10A Power supply, If each of these peltier draws less current (divided current) both chill and hot side will be very less, try using 30A power supply, may that will provide enough current and Real AC effect + use Thermal compound for efficient heat and freeze transfer, but then again it will freeze fast, you may need to use high Rotation fan (16000rpm) for efficiency, Just my thought.
Yes it can. Use peltier module in conjunction with a swamp cool/water cooler. Use it to cool the recirculating water with probably 3 or 4 modules and the air you would get to almost freezing in no time.
Large Space cooling ? yeah can be achieved. Fans come in CFM cubic feet per minute size. So if your LArge room is about 20ft x 20ft , and you're fan has max 60cfm capacity, then you will need 20x20 = 400 sq.ft / Divd by 60 cfm = 6 Fans of such cfm value. But you will need 12 fans of such cfm value, 6 fans of 60cfm value and 6 fans(heat throwing) of higher than 60cfm value. Peltier : you will need peltier qty as per above video multiplication. 1 Fan with 4 peltiers so 6 Fans peltier qty will be will be ??? 6 x 4 = 24 peltiers Total System Cost will be yeah much highe 24 pelts x 200INR = 4800 INR (USD approx $70) 12 Fans x 250INR = 3000 INR (USD approx $60) 24 Heat Sinks x 200 INR = 4800 INR (USD approx $70) Insulation, wires, smps = 8000 INR ( USD approx $150) acrylic fom sheet etc. Total System Cost = 20,600 INR (USD approx $300)

If you like the suggestion, then reply.
Nice model. But only 2 to 3 degree C fall in temperature is not expected while watching. Keep rocking. Bdw which material is that which looks like dense thermacole? I think it will consume too much Power (wattage).
you really need to find a more effective design and use better materials such as thermal paste and better bonding. . What you built is ineffective (only 3°C interior temperature difference) and wont last very long, since a glue gun creates just a temporary bond, especially on the hot side of the module. but i don’t want to discourage you. there is always something that can be improved in everything. everybody is constantly learning. even the best... especially the best.

LOOOOLL.... 4 peltier useing power supply 10A.....hahahahahaha so funny 1 peltier 6A make parallel 6A x 4 = 24A and that doesn't include fans.....it is not enough to cool the room
4 Peltier x 6 A is not equal to 24 A. hahahah If you connect all +pos. to one 2mm wire and 2mm wire to SMPS +pos then it's just 4/5 A likewise all grounds need to be joint/soldred to one 2mm good wire --- > SMPS -neg. it's just simple Yes you need a Resistor for cpu fan it needs only 1A and 12v, so add 7812 regulator IC for max. 1 A Output Total Wattage of System = 1A Fan x 12v x 2 pcs = 24 W 6A Peltier x 12v = 72 W Total system watt = 96 Watts DC THE AIR CONDITIONER MADE BY THE PERSON IS CALLED WINDOW AIR CONDITIONER And not Split one. So You need a Hollow Window in room facing gallery / backside lawn , so it will cool by throwing hotness of peltier. ACs work similarly. In new age of Split AC, The Box is cut into 2 pieces, but working remains the same ! It doesn't throw out hot air of room, it just cools room air and throw away AC System Heat outside
Buen vídeo compañero...pero otra vez me deja de poner la pasta térmica, con lo cual, el rendimiento de sus células Peltier no es el idóneo....gracias por compartir...
This is really good brother. Now try to discover a way to drop the temperature even further. The thermal compound grease as already suggested will improve things. Personally I would have the fans directly bolted to the sinks. There are obviously many ways to skin a cat. 5☆ for good honor and effort...
Air needs to sweep over maximum possible length over the heatsink fins for better conduction. Design and placement of components is perfect. I liked it 👌
Ok but what about the hot air exhaust. You need to let the hot air go outside the room otherwise I am afraid that the overall effect could be increasing the temperature rather than cooling.
Nice that at one end cool air comes out, now, if you blow the hot air out of the back you did not gain much.... You need that hot air out of the room.... that is the idea of an air conditioner.
It can drop if you put it in a closed area and eliminate the hot part.. then the cold air from the fan can circulate back so that it can get cooler and cooler.
What I am about to say, although the video is impressive, has nothing to do with the work being carried out by you. I would like to inform you, or whoever reads my comments, and you will hopefully spread the word around that, instead of using the very expensive thermo-paste, you may want to use: Copper slip, its results are just as good at a fraction of a price. The thermo-paste syringe of 10 milligrams probably costs about 5 pounds sterlings, whereas a 500 gram tin or tube will set you back: 10 pounds sterling. Please pass the news around, thank you!

The hot side of the TEC needs around 4 times the heatsink surface area than the cold side does.

you're welcome
From where you had bought the assembled peltier?
I think he used 4 x 6A Peltier with 10A Power supply, If each of these peltier draws less current (divided current) both chill and hot side will be very less, try using 30A power supply, may that will provide enough current and Real AC effect + use Thermal compound for efficient heat and freeze transfer, but then again it will freeze fast, you may need to use high Rotation fan (16000rpm) for efficiency, Just my thought.
"freeze transfer" is not a thing. Only heat transfer exists. Cold is just lack of heat. Because it has been transferred elsewhere.
Thermometer tail should sense room temperature, not the module cold side temperature.
This method cannot be used to cool a large space economically.
Yes it can. Use peltier module in conjunction with a swamp cool/water cooler. Use it to cool the recirculating water with probably 3 or 4 modules and the air you would get to almost freezing in no time.
Large Space cooling ? yeah can be achieved. Fans come in CFM cubic feet per minute size.
So if your LArge room is about 20ft x 20ft , and you're fan has max 60cfm capacity, then you will need
20x20 = 400 sq.ft / Divd by 60 cfm = 6 Fans of such cfm value.
But you will need 12 fans of such cfm value, 6 fans of 60cfm value and 6 fans(heat throwing) of higher
than 60cfm value.
Peltier : you will need peltier qty as per above video multiplication. 1 Fan with 4 peltiers
so 6 Fans peltier qty will be will be ???
6 x 4 = 24 peltiers
Total System Cost will be yeah much highe
24 pelts x 200INR = 4800 INR (USD approx $70)
12 Fans x 250INR = 3000 INR (USD approx $60)
24 Heat Sinks x 200 INR = 4800 INR (USD approx $70)
Insulation, wires, smps = 8000 INR ( USD approx $150)

If you like the suggestion, then reply.
How much power consumption?
Nice model. But only 2 to 3 degree C fall in temperature is not expected while watching. Keep rocking. Bdw which material is that which looks like dense thermacole? I think it will consume too much Power (wattage).
Nice concept.. but if you place the waterblock+aquarium pump will result to reduce the hot side...
Can it be used directly on 220V AC
you really need to find a more effective design and use better materials such as thermal paste and better bonding. . What you built is ineffective (only 3°C interior temperature difference) and wont last very long, since a glue gun creates just a temporary bond, especially on the hot side of the module.
but i don’t want to discourage you. there is always something that can be improved in everything.
everybody is constantly learning. even the best... especially the best.
U r using 4* pelteir module each 6amps and u are giving only 10amps u have to use minimum 12v 30amps for this 4 pelteir module 👍
Can I get room temperature about 17 degree celsius?
Which bord u used for body
1 धागे वाला काम कच्चा है
2 Fen ko Air kahi se bhi nahi mil rahi
3 Fen ko cold wale or hot wale jagh ke samne lagana tha.
4 itni mehnat ki sab bekar cahli gye.
LOOOOLL.... 4 peltier useing power supply 10A.....hahahahahaha so funny 1 peltier 6A make parallel 6A x 4 = 24A and that doesn't include fans.....it is not enough to cool the room
4 Peltier x 6 A is not equal to 24 A. hahahah
If you connect all +pos. to one 2mm wire and 2mm wire to SMPS +pos then it's just 4/5 A
likewise all grounds need to be joint/soldred to one 2mm good wire --- > SMPS -neg. it's just simple
Yes you need a Resistor for cpu fan it needs only 1A and 12v, so add 7812 regulator IC for max. 1 A Output
Total Wattage of System =
1A Fan x 12v x 2 pcs = 24 W
6A Peltier x 12v = 72 W
Total system watt = 96 Watts DC
THE AIR CONDITIONER MADE BY THE PERSON IS CALLED WINDOW AIR CONDITIONER
And not Split one. So You need a Hollow Window in room facing gallery / backside lawn , so it will cool by throwing hotness of peltier. ACs work similarly.
In new age of Split AC, The Box is cut into 2 pieces, but working remains the same ! It doesn't throw out hot air
of room, it just cools room air and throw away AC System Heat outside
The idea is good, but I want you to help me with this question: to run 3 or 4 12v fans is it necessary to use those peltiers?
Any one can answer this question? Because we are the same question
what material did you use to build the fairing of this portable air conditioner?
don't know
Hey bro I liked the song Lol😆 Relaxing Who's the writer of the tune Please get back thank you😉
Which board do you use? What is the name Of that board?
Bhai hot side m thermal paste lsgane se jaida cooling milta
Best pure country music,many thanks for the explanation,thanks also patietly.
Writing the HOT and COLD on both sides. Why just only HOT and the other side must be COLD.
IS there any other phase?
Buen vídeo compañero...pero otra vez me deja de poner la pasta térmica, con lo cual, el rendimiento de sus células Peltier no es el idóneo....gracias por compartir...
Sir peiltier module ko 11v 6 ampere se chala sakte hai kya
Bhai ye jo pura outer box ya case jisse pura cover kuya white colour ka thick cardboard jesa kya he?
Will this ac cool an area of 10 feets
This is really good brother. Now try to discover a way to drop the temperature even further. The thermal compound grease as already suggested will improve things. Personally I would have the fans directly bolted to the sinks. There are obviously many ways to skin a cat.
5☆ for good honor and effort...
Good job!😊
Bhai aisa mere liye bhi bana dega kya, rajasthan border par bohot garmi h
Good job 👍👍👍👍👍
How long is the active period for peltier, or how many hours is the active peeiod.. thnk
Itu heatsink yang bagian hot apa tidak terlalu panas mbah,,soalnya tidak di kipas langsung,,
In my country, now, the temperature about 48 degree, if i use the peltier , it is go down to 46 only 2 degree🤔 so i still 😥
Well i believe peltier is not meant for countries like ours. We get 55 degrees some time
Air needs to sweep over maximum possible length over the heatsink fins for better conduction. Design and placement of components is perfect. I liked it 👌
Gobble goblin to the show is a bit more about our products
That was more width than length, should have put them side by side elongated not on top of each other in my opinion
Where did you got your heatsink? Is it from a computer?

Ok but what about the hot air exhaust. You need to let the hot air go outside the room otherwise I am afraid that the overall effect could be increasing the temperature rather than cooling.
81f is not bad, some improvements could be made, would love to see 33f out of this but must settle for 81f.
Nice that at one end cool air comes out, now, if you blow the hot air out of the back you did not gain much.... You need that hot air out of the room.... that is the idea of an air conditioner.
The glue will melt on the hot side.
Can u control the temperature?
yes can

Each 12706 peltier draws upto 6amps, you are joining 4 in parallel with a 1sqmm wire, you are making a recipie for a fire!
Very nice and good vedio.
Bhai ki mehnat ko slam
can use it for whole night?
temp must be more drop from 27c this is not reasonable
It can drop if you put it in a closed area and eliminate the hot part.. then the cold air from the fan can circulate back so that it can get cooler and cooler.
Well done 😊
Bhai ye kitna time tak chal sakta hai?
Excellent work!
What is the white strip? Is this tharmocol
Bro I appreciate your intelligence & must say it's a brilliant idea. Good luck for future projects.
What I am about to say, although the video is impressive, has nothing to do with the work being carried out by you. I would like to inform you, or whoever reads my comments, and you will hopefully spread the word around that, instead of using the very expensive thermo-paste, you may want to use: Copper slip, its results are just as good at a fraction of a price. The thermo-paste syringe of 10 milligrams probably costs about 5 pounds sterlings, whereas a 500 gram tin or tube will set you back: 10 pounds sterling. Please pass the news around, thank you!
