You went to all that trouble to produce this, and the whole point was to show the cooling effect, but never put a thermometer in front to show how it cooled. Why?
Porque dessa forma não funciona, isso é inútil!
@@dfx9798 🤣
Porque nao funciona, por isso
If anyone is wondering, this is how they make heating and cooling seats in cars. You don't even need to turn the peltiers over. You just switch the polarity. He may have made an AC for the summer. But he also just made a heater for the winter.
this means that the heat he is releasing in the winter will just be cooled down from the other side and vice versa so no change in the room temperature
@@RaniRani-zt2tr exactly
As an Engineer to a colleague - I just love how you placed your power source cables right on top of a 70 c heat exhaust. Now, that is just a beginning of an ocean of problems for this - wrong - toxic (nitrates producing) potentially explosive assembly.
This stuff is very exciting and I'm in the project of designing an insect farm with peltier heating and cooling but I'd be very happy to get some support. Please, contact me
Exactly, maybe he could wrap em up in fibres
As an engineer I'm confused, there is no ammonia, so how can their be nitrate diffusion? It's not like he's using this as a cooler housing food... I highly doubt you are an engineer
So im trying to make one as well but where do i put the power supply? On top of the cold side? Or where?
Vc esta errado. Não tem nada haver o q vc disse. O dispositivo nao funciona, mas dai dizer q produz nitratos? Vc está louco?
i was waiting for temp. test at the end

For the 4 smaller fan are they blowing air in or out ?
What will happen to the condensed air inside ?
@@arifinsoekamto the smaller one is blowing out..on the back it cools the heat sink
@Flavio Felix Estas coisas são demasiado ineficientes. Gastam demasiada energia para apenas um ventilador que não chega aos calcanhares de um ar condicionado normal. Servem apenas para pequenos frigoríficos infelizmente
Unless your going to be hanging the back outside a window your making more heat on one side then producing cold. Plus the electric for these are high.
ifell3 yes I agreed!!!
Agreed
Took the words out of my mouth. Not to mention it's very inefficient.
took the words out of my pc keyboard :)
Who said it was efficient? It is just effective. Any air cooling system produces heat by the other side, your refrigerator, freezer, air conditioner... anything. why do you think they are installed out the window? Your refrigerator or freezer cools inside the box, but touch outside back in the pipes.. it's hot. Stupid noobs. Pd: the same way air conditioners, copper pipes get hot as my dick that's why it has giant fan outside the room to cool the presurized gas inside pipes...
Nice job man.......!Great .I like it but you can add a drain pipe for water of ice when it melts .Thanks a lot .keep going.
That is absolute genius, Kenh!!
It would be nice if you showed us the ambient temperature as well as the output temperature. We would also like to know the total energy consumption. Hard to know why you overlooked those critical items.
It's very inefficient. Likely consumes upwards of 500 watts and doesn't work
why bother to make this if you dont show us the output of the box. Temps power used etc.
with those peltiers about 200w
The original version placing in window seems to be here

Peppa pig
Yea he doesnt even prove it works as an air con... i wouldnt even bother trying to make this without any proof it works... so pretty wasted video
I will give it credit though after watching this and several other videos on attempts to make one of these i have come up with what i believe to be an optimal and effective design for a desktop aircon using the peltier modules....
Nice Room heater. Great for cold Days in Winter.
Exactly
suppose to be an AC for summer but it works both ways or it does not work in any ways because the heat will be cooled from the other side so no change in room temperature
@@RaniRani-zt2tr unless yo use your phantasie and good willing mindset than you understand that a tube can solve this and maybe on other ccuntries the windows are made different so you can just easy attach it at a window and close gaps with styropore...just in case you didnt find a positive mindset :))
@@LetsFixITJoe yeah you are 💯percent correct but the problem is that not everyone has the perfect windows and that not everyone knows that AN EXHAUST IS REQUIRED TO AFFECT ROOM TEMPERATURE 🙃🙂🙂
@@RaniRani-zt2tr its not about the perfect wiindow...jsut told you that there are a hughe differences in windows internationally...and its up to you to find the best solutions for that :)
any child knows about the need of a exhaust ;)
by the way, if you have a solution there was never a "problem"
A very informative practical video just requires some V/O as well. I’m not sure about how well it actually worked but you are very good at measuring & building with Aluminium. 😀
Good job on making a solid state air conditioner( no compressor) ,that is awesome!
congrats, you built a heater ;)
One of the better ones that I've seen made in youtube.
It's always good to have the correct tools. Makes projects a lot easier and cleaner!
An amazing concept, however, unfortunately the most inefficient air conditioner in the world lol
Also, he leave the fans on cooler side taking air from out of the heatsink, no sense, he will take air from out of box directly to fans, without going through the heatsink first. He had two options, or put the fans directly on the heatsink, so that the fans could only grab air from the heatsink, or the second option was to put a cap around the heatsink to force the air to go through the heatsink first before pass to the fans.
It is also very inefficient, you cannot cool a room with it, although you could make a smaller version with one or two peltiers to keep temperatures inside a computer case low if you have a very high ambient temperature. or even on an electric control board

You are A Perfect Teacher
👌👌
Nice build, there are a number of reasons why this won’t be effective though. Peltiers are 2% efficient, that’s the first. Not having said that it was for a particular size area or any specific application it would have been good to see the temp of the cold air expelled. I’d like to see this principle, or indeed this particular model adapted to a cooler box. The heat pump effect would not be an issue. Having said that it would be too “power hungry” for a mobile application. So I guess “Home made Beer Fridge” might be the go.
The other interesting point with peltiers is that they can keep a small area or amount of medium very cold but apparently cannot get the initial temperature drop to their efficient operating temperature with larger areas.
Cooling a circulating fluid was mentioned in a few of the comments , now that MAY have potential. Just Saying
They are about 2% efficient at generating power. They are much MUCH more efficient at cooling.
i made a similar project few months before....in my design i just used two peltiers (consumes only 5A each)...in order to increase efficiency you need to pulse the input current...by using an IGBT or a MOSFET. the peltiers can handle 2x more power when its input supply is pulsed at high frequncy, and also removing much heat from the hot side can improve its performance...say pressured gas loop....
PS: i made a refrigerator..not an Air Con..cause there would be a lot of work for an isolated air con.
and which temperature you achieved?
I water cooled hot side heat sink and it got down to negative 18 degrees Celsius on cold side so adding a home made water spray kit like a winscreen washer setup works great as long the radiator your using is like a transmission cooler with high power cpu fans
Hi, do you have some papers about it? I am interest in peltier cooling but I don't want to loss efficiency.
Or watercooling systems, like from CPUs.
Mosfets are bad for peltiers. The constant switching on/off allows the heat to transfer from the hot side to the cold side for the micro seconds the mosfet turns off. It's better to have a constant current.
I recommend putting the AC at a window to create temperature differences. Overall, nice work!
I love how the heat from the peltier just warms up the room more then it can get cooled down
🤣🤣The guy who made this video doesn't think things through
@@kiyoponnn what happened with the window AC installed in the room except outer window.
@@IMRANKHAN-we9un ?
It's like window ac
@@KP-tb5jo Nope, even a window AC has better efficiency than this
Smart idea, neat and well organized work but... at least you could have put a thermometer in front of it to show us how efficient is your set.
Jamal Aldeen it doesn't work.
Without the hot side being exhausted to outside you will actually heat the room. What happens to all the condensate from the cold side? You need a drain pan. Back to the drawing board.
Well, that is why he just build the equipment but did not test. Maybe it is useless, but it looks nice as decoration.
... the fans pull the opposite way? what
Unless the device is fixed to an opening on the outer wall of a room, the heat generated by peltier would be ejected to the inside of the room itself even though the other side of the device will be ejecting cooled air. So these will compensate each other and the room will not be cooled ! He has not shown us the temperature of the room after the device was switched on !
He has wrongly fitted peltier module. Hot side of peltier module must be on the heat sink.
Awesome
absolutely amazing superb
OK. Measurements? Results?Effectiveness? Tempreature? What are you doing with the moisturisation?
everyone mine isnt any better its just a nice cooler (not ac) check it out please ruclips.net/video/TtRkd-rITkU/видео.html
Cooling and heating up the room at the same time :D lol
Like a portable AC cool air out the front and hot air out the back though the hose that get hot so any actual cooling from the front is negated by the hot hose exhaust.
So heating it basically
yeah if u had a duct pumping the heat from the back out a window it might work great then u just need a dehumidifier
You dingy you put the heat part out a window, like an ac
@@Peter_Yachymczyk kokkkkkk
Wow i like it
switching in rush current on the DC side of 12v, 30A. dope idea.
Will it work
Peltier is making more heat than coolness, so if it's supposed to work the hot air must be discharged to the outside.

I like it... good demonstration of the principle.
me parece bueno, solo te falta agregarle algun conector tipo manguera para que saques el calor hacia otro lado y no elimine el efecto
El sistema está echo para sacar una parte fuera del ambiente esta muy bien echo
I think you should have placed a thermometer nearby to measure the temperature generated by the box.
It's good ideas PUT us need Experience
Many thank to you Great work only i wanna to ask you is there Difference between 12706 and 19906 from more Effect .
really thank you great work
Use glasswool insulation to insulate the inside part from the outside part. Also use a closed-loop cooling system using a mixture of car antifreeze and water (1:1).
Appreciate your efforts , nice video . Hey can you tell me what is the temperature at the cooler and what is at the hotter part
Hahaha.. same doubt
ñn
Nice little rig though!👍
Also add some details of products,
After u have done the project, show us output like temp, electric used etc.
faltou mostrar com um termómetro a temperatura que essa jóia da!
To reduce the wattage, put seabeck devices on hotter side and submerge another side of seabeck devices to generate little electricity and heat the water to be used for other kitchen purposes.
Was thinking the same.....😋😋
I like this
Excellent
Good idea, good building skills BUT DUDE you didn't provide any Infrared Temps? Input/Output TEMPS or Watts or RPM, or CFM flow??
REUPLOAD WITH THIS!
everyone mine isnt any better its just a nice cooler (not ac) check it out please ruclips.net/video/TtRkd-rITkU/видео.html
there was no temperature checking before after?
Right
The idea is nice. Would maybe use heatsinks like the cold-side one for both sides and then have the fans blow in one direction over it making it possible to exhaust the hot air out of the room.
It is perfect !
1- the fans on the front are not close enough to the cold sink, causing a not very optimal air flow.
2- The cold sink side is probably going to build up condensation.
3- Hot air in the back will just go around to the cold side, and leave the room hotter than it was before. Peltier elements (same system like this), generate heat, they do not cool.
4- Might work ok as a dehumidifier, or a space cooler, but that's it.
To make it work effectively, the hot side of the peltier should be outside the room...else there's no use of this cooler..
Fact bro
@@bijukurian7 we could stick it halfway out the window like the old coolers. Me and my friends are looking to build this for the summer.
Correct. The fans need to be virtually in contact with the heatsink fins (CPU coolers are OK,) to force as much air as possible thru the fins, and in contact with the grill so there's no recirculation of air for either heating or cooling spaces. Also, bolts etc passing from the hot space to the cold should ideally have thermal insulating washers between them and at least one of the heatsinks (a washer with a hollow collar, like transistors use) or should be non-metallic bolts. This especially applies to the 2 bolts fixing the heatsinks to each other! They are a direct thermally conductive path from the hottest point of the hot side to the coldest point on the cold side, and form a perfect heat shunt in this design!
Two thoughts on this. First, this would be really useful while camping provided you had a solar panel and a battery to hook it up to. Second, 5 ads on an 11 minute video?? Holy crap that's excessive.
Looks Great Brother ❤️ thansk
The peltirr device will eventually stop producing a cold side just one side that is significantly cooler than the other but the if the hot side jumps up to a crazy temp you will have a warm box
This is actually an electric heater....
That would depend upon the polarity of the TEC's.
@@Omastian It would depend upon whether or not you exhausted the waste heat to the outside of the room being cooled.
One side heating, another side cooling
What is the material the box is made from??
@@wishdrftr it appears to be what's sometimes referred to as alupanel which is an aluminum clad (alu) plastic sheet (usually LDPE). It's quite handy stuff.
Nice project 🎉
It’s cool...!!!
Congratulations! Your system is less than 1/3rd the efficiency of a compressor/condenser evaporative system...
Except it vents into the same room...

no If you connect several of this device in cascade and put them on the maximum coe state. In theory you could get a COE over 2
@@oscarservices8035 Hey are you an engineer? I'm a product designer working on some cool things for some cool clients, let me know if we can work together?
Yet it uses no refrigerant.
🐸 very disappointing vid! Not even one temperature mesurement at the of the vid 🤣very well made box for birds though✔️
Not very efficient design either. I'm pretty sure temperature of the air stream blowing out is also disappointing with only minimal drop in temperature. 🙄
Funneling all the air into the sink before blowing out would be more effective than just having it in a big box with a lot of the moving air not in contact with the fins.
Inspired by many such videos I experimented with 2 peltiers on two sides of 80x80 mm piece of car radiator weighing about 78 gms.
It could lower temperature of piece by 20 °C from ambient temperature without cpu cooling fan (80 mm rated 21cfm).
But when fan was switched on, the piece quickly returned to ambient temperature despite peltiers were working.
Thus very small objects can be cooled with peltiers with direct contact without fan.
For AC for cooling room in the air perfaps 1000 peltiers together can't work and imagine the power that it will consume.
At least he's trying do you know how Manny times it took to make the lightbulb or the airplane? You don't know how old or what resources he may or may not have, that's so narcissistic; tbh it's you that sounds like a disappointment (and this is coming from a furry lol) by downing someone like this just kuz you can and probably don't feel enough validation in your life.
everyone mine isnt any better its just a nice cooler (not ac) check it out please ruclips.net/video/TtRkd-rITkU/видео.html
i like it, you did a very nice job
the room just got hotter with this heater
peltier = 400w, (100 btus + -) 24h/D = 9.6kw
air conditioner 7500 btus 900w 10h/D = 9 kw
Very inefficent
xD
Why is that inefficient? In 10hrs per day of using AC you would consume 9kW while in 10hrs of using this diy peltier AC you could only consume 4kW..
cooling capacity is low compare to ac
10h of peltier cools way less than 10h of AC, look at the btus
This is a neat idea although it would never be super efficient or a high output cooling device but it's definitely a fun project, some ideas that would improve the design would be: first you need to vent the hot side out of the room for two reason one is you don't want that heat circulating back into the room but mostly because as that heat circulates it continues to heat those peltier chips and that lowers the cooling efficiency, remember as the hot side heats you lose cooling so circulation away from this side is key. Now another design flaw I seen is on the cooling side, you should of directed the flow of air pass the the heat sink along the aluminum fins. Put the intake on one side and the exhaust on the other and drop the top lower so it is close to the fins and forcing the air to run through the fins and not around it then the air will cool before it exits the exhaust vent. These are just a couple thought for what it's worth. This is a neat project and looks like fun thank you for sharing.
What kind of board they used to put peltier? Any body knows exact name or term for that board. Tnx
SunBoard
What you really should do with this is submerse the heat(cold) sink in water. Water can freeze around the fins offering longer cooling. You can even shut the peltiers off after a certain amount of time to save on electricity. These put off alot of heat it's a good idea to figure out a way to vent the heat to the outside just like a traditional ac. Or just put a few up into your ceiling and vent the heat into the attic.
👏 amazing 👏 It's a good video
Eficiencia muito baixa para o uso "domestico:...
peltier = 400w, (100 btus + -) 24h/D = 9.6kw
A/C = 7500 btus 900w 10h/D = 9 kw
75 vezes menos eficiente, ou seja: "custa" 75 vezes mais em energia.
Mas achei interessante o processo de montagem! Deu pra aprender algumas "tecnicas". Obrigado por compartilhar conosco!
I was looking at this to cool a van conversion until your reply. Your reply was very good and I was wondering what you might suggest to use to cool a van conversion with 12 or 24 volt? There are many 110 volt units but very few 12 volt that I could find. There are 12 volt Marine units with water cooled condensers but not 5k to 10k btu units that use air to cool condenser. With 12 volt you don’t have the losses of the inverter. Clearly you know your electrical engineering!
Needs a secondary switch to turn on the cold side fans since you may want cold air blowing, not room temp air.
Needs an exhaust vent to a window at a minimum. However, if you stored heat in water and could sewer the water so the heat is lost, that would be more effective standing alone.
Very expensive cooling with required upgrades, only adds heat to a room without the fixes.
Nice Room Heating Unit =)
😀😀😀
nice / but you should fix a tempreature display also
Id love to see the video end with a thermometer in front of the unit to show its actual temp of the output air. And one in the back to see if the cold output is higher or lower than the heat generated to provide the cold.
You could use a split adaption to vent heat side out and cold side in separate
Looked like way to much thermal compound. Thermal paste still has resistance. You should only use a thin layer.

True, he should of put the same amount as you would on a cpu.
good idea ....... for air conditioning.but peltier suits to refrigeration of both hot food items and cold food items as we fix peltier modules with an insulating material at centre..chilled side is used for cold food like ice creams and drinks.,,,and hot side is used for bakery items like puffs,rolls,etc....so that its heat is also be utilised with mini refrigeration
Cool, What about measurements like temperature reduction and power consumption?

Nice sir
Bro it will produce more heat then cool air in same room . Let thet heat output side be out the room
nice but dude, you must encapsulate and add a tube to the exterior, this way the heat of the peltier is moved out and inside is just kept the cool air,

p.s. just in case any haven't understood, you mount this inside your house to an external vent or to an open window and use board to block up the rest of the space. If you just plonk it on the coffee table and turn it on you wont find any difference unless your house has stopped obeying the laws of thermodynamics.

@@AnimMouse the "ac" still has no way to vent the air. It should have a ventilation tube or something.
The problem with this air conditioner is it's efficiency ,because peltier is producing heat and it produces cold and it also consumes 240w of power.
240 watt for the 4 peltiers alone, let alone the power to run the fans, .... might as well using 300 watt real Air Conditioning
Anyways but a real ac consumes more than a thousand watts ....
Yes but a real air conditioner consume 1000w or 2000w sooo
Its very inefficient but its probably only for demo purposes
A normal air conditioner 12 btu consumes about 300w. Why should do this?

Excellent!!!! but just one question, what is the energy expenditure that it consumes in operation?
It's an interesting idea, especially as a diy teaching tool.not sure what use it could be considered efficient in; since I am not well versed in the "Peltier Thermoelectric Effect". It is interesting.
Ola Hello, this is brazil. I really liked your channel friend.
Looks interesting but that’s it. This thing is completely useless because it’ll output more heat in the same room instead of cooling it down. Because the one side of the Peltier gets cold an the other gets hot. And as the other side gets hotter the cold side will begin to heat up as well. Plus the hot air from the hot side is being blown into the same room you’re trying to cool down. It just doesn’t make sense.
Use it like aircon window type. Are you satisfide wih that?
archer anthony canete great then I need to make a 1.40x1.40 Meter (55x55 inch) big Peltier Module... that wastes so much power.
after all .....hearts up.....nice bro
With this, you might be able to cool a small closet if it were heavily insulated.
By one side produce hot air, by the opposite side cold air......
Sum is equal zero......
Sum is not zero but 100's of watts of heat generated.
actually is zero plus the heat used to do the work, wich adds up to more heat
