*Needed a cooler for a work cubicle **Fastly.Cool** . It did just what I needed, so easy to used and really cooled the space. I am glad that I got it and would buy it again.*
Nice looking product. I especially like the temp display and the massive heat sink. Earlier today I couldn't find the tall square ss pipe i was looking for but found an aluminum one shaped very much like yours.
I am in the coffee business for 20 years, and we use Peltier cooling for the syrup instant coffee dispensed in our machines. What Cyprian Guerra says is absolutely correct. There are several problems here: 1) In such a cabinet, it will not cool a room, because Peltier cooling generates heat on the back side, and it is the heat that needs to be vented away, or else the Peltier element will burn out quickly. It would require a bigger (6 times larger) heat-sink than the one he uses, and a fan 2 to 4 times larger than the fan he uses on the back. It would need to be mounted in a window or other specially-made opening, with a heat-sink and fan on the backside to vent the heat away from the element. 2) He lies when he uses the words "surrounding " or "ambient" temperature. No room, would heat up that fast, and if it had gone so quickly from 30+ degrees to 10 degrees, he'd have put a coat on very quickly. The thermometer must have been mounted somewhere on the front, probably behind the display itself, so he was not measuring the temperature of the surrounding air , but the temperature of the face of the Peltier element itself. A very small chamber on our coffee machines where the liquid instant coffee is held, takes 4 to six hours to reach 5 degrees, and that is only sufficient for 3 litres of syrup, in a closed, insulated box. To cool a room of 30+ degrees down to 10 degrees would likely take 24 hours or more, and only if the room was lined with cork or some other insulating material, or the coolness would dissipate through the walls before the room could cool. 3) Finally, a Peltier element uses quite a bit of electricity, and would not be economical for such a use, or else you would see mass-marketing of Peltier air-co units world-wide. Peltier elements are also not cheap. The device as he shows here, would burn up in a matter of days (or hours) from improper dispersal of heat, the most common cause of breakdown in the field is either from dusty fans that become blocked, or if the machine is placed against the wall, so that the fan can't get rid of the generated heat. It's simple thermodynamics that you can't cool without generating heat, as actually you are not creating cold air, you are venting hot air to cool the desired area. I have used them with picnic cooling boxes in my car, plugged into the cigarette lighter with an adaptor, to keep my lunch cold while in the field doing repairs all day long in the summer.
Agree. The approach in the video in the isoluted room will increased the average tempersture. The only assumption - theoritically the excess of the heat could be regenereted back into electricity and accumulated by another set of Peltier modules. To reduce the temperature means to relocate thevenergy to another place or regenerate. My goal is to use the thermoelectric effect in the air heat exchanger - ventilation system as a heat pump.
"he lies" might be a rather big statement. Some part of this is due to translation issues, English is probably his second or third language. (And there's differences/MTI/NTI when you use English coming from a different native language vastly different from it) What you point out re cooling efficiency etc., is true, and to some extent he mentions the same wrt saying "packing" is required. Which contextually/colloquially is taken to assume that venting + some insulation is required. It's a great medium to exchange information, let's not assume everyone speaks a foreign (English) language the same way.
#1. You should have used a heatsink on the cooling side too. #2. The thermostat sensor should be placed on the Air-Outlet to get the actual temperature of air flowing out of the Air-condition. Thanks👍
This is a great idea thanks ! I need to cool down a 5x10' darkroom. This just might work or maybe 2 of them. Don't pay attention to the Monday morning quaterbacks.
great AC and the best looking I've seen so far. For better efficiency, you should add a heat sink to the cold side so the air can flow over it inside the Box.
I am trying to set up a peltier 12706, supplying power from a 12 Volt, 6 Amp transformer rectifying & filtering it into 12 V DC. At first the heat sinks on the hot side is heating up and cold side is cooling respectively. A few minutes later the cold side is also heating up. How to rectify this?
the temperature indicator is merely showing the Peltier temperature, not the ambient temperature。 it does not make sense to use Peltier to cool the surrounding, this is the very inefficient device anyway, you have a done a nice job of creating this cooling device。
Actually I ran my peltier module on 12v 2amp adapter and it works and makes the peltier cool and hot but after 2 to 3 minutes the 12v 2amp adapter starts it's indicator light to turn off and then on after some time. So, is there any solution for this problem or should I have to use a bigger ampere power source or something else?
I have a question. I also made a water cooling Perrier air conditioner, but asap dc fan in to draw the cold air is turned on the peltier temp start to go back up on the cold side . What ami doing wrong?
my room is present in the center of my house.... i have to keep in to table close to my bed.... there is no window present there for dumping heat outside.... it will work???
Hi.. wen I tried to connect all the 3 products. 1 peltier, 2 fans.. but the speed of the fan has decreased can some 1 describe how is that possible. Do I need to buy the higher voltage adaptor for this do the power is supplied exactly?
Use 12 volt supply only but carefully calculate the ampere of total, by applying less ampere will slow down the system. It will be better to use 12 volt 10 ampere supply.
temperature sensore at air outflow and further into the room would be good. For me i would add some insulation in the box or under the box (outside) to reduce the fan noise. I don't think my neighbors would like that sound. I wonder if a duct reducer is on the outside, and using a bigger fan would also work. i think i would prefer using a larger quieter fan, like 120mm or 140mm.
Yeah, nice heater you've got there. One side of the Peltier module gets hot while the other one gets cold, overall heating the environment due to low efficiency.
Cyprian Guerra works just like a regular window ac which also works on the peltier effect. Which is why he put the hot end pointing outside when he did his demonstration on window mounting. He knows what he is doing. Edit: in essence both this unit and a window mounted ac are performing in the same way. Hot air outside, cool air inside. Window mounted ACs operate under a different effect than peltier modules do.
Panic The Scholar Knight. Real window AC works due to gas compression (Carnot's effect) and has nothing to do with Peltier's module, it's tens of times more efficient and process can be reversed to heating easily, e.g. in winter. Entirely different device and you either don't know what you're talking about or we seriously misunderstood each other.
Cyprian Guerra no, you're right. Window mount air conditioners work on carnots effect. Thank you for proving me wrong. However, the technical machinations of both of these units are the same. Heat is pulled out one end and cool air out of the other. In his example partway through the video, he had it mounted in the window like a standard window mounted AC. The hot air was vented out and the cool air was vented inside the room. The heatsinks are adequate for the unit. All in all he did a good job with what he had.
Though its kind of hard to hear due to the noise and sound quality he does mention this is designed for cooling at maximum a 6 foot by 6 foot enclosed area assumedly with the hot side venting to an external environment - though in my experience you'd need more like a dozen of these devices to produce a significant change in an area of that volume using regular TEC1 12V Peltier modules.
When I say significant change I mean - you can run it a few hours and see any temperature drop in the scale of whole degree Celsius at all - you'd need far more to come remotely close to what you can do with a proper AC unit.
Simple and easy, like that! How long you can power this? Eeach peltier takes about 10A plus fan its maybe about 25A total. The accu look like close 20Ah which means it runs for less an hour or maybe 30min?
8:36 the fan will suck air into the unit not blow out the front... plus this doesn`t make sense.... cooling equals hot side vs cold side, it `s like saying leaving the freezer door open will cool the room
You need to use your imagination and put the hot side outside of the area you are trying to cool just like a window air conditioner or put the hot side inside if you're trying to heat a space. I want to cool my bunny Hutch
you also need a small heat sink on the cold side along with a little fan to actually pump some of that could air out of your box. also you should setup the peltiers in a cascade. supply the bottom with 12 volts then put the hot side of the second onto the cold side of the first one and supply the top one with 5 volts. It will work waaay better. for best results, you should liquid cool the hot side and pump that hot air outside.
The Peltier system is pretty interesting oh, I'd like to hear more of what you have to say. Your video reminds me of a silent movie. What kind of glue are you using is that some kind of dielectric something or other? Great idea good video needs sound and words. Thanks Guy Good Luck Good Health to you
Bhiya temperature sensor ke pin ko apne peltier ke upar kyu laga Diya hai, iss terah to wo peltier ka temperature show karega but hame to room temp kam hote hue dekhna hai.
excellent concept but a bit noisy. Also you appear to be reading the temperature inside the box while a reading at the outlet of the box would be more appropriate. How much power do you use. I hear peltier are only around 5% efficient.
very good demo. Thanks for sharing. Can you please share where you have sourced copper heat sink and powerfull fan?. I wish to do the same to cool helmet.
It seems you used metal box not plastic box. However I find here few technical issues: (1) What's the max. temperature to be safe for this Peltier unit? (2) How long we can continue the unit at a stretch? (3) There is no heat sensor circuit to cut off the power supply after getting desired temp. or any delay circuit to protect the fan and other parts.
It can reduce temperature of small spaces like mini camping tents. Or it can be used as desk cooling fan by adding a flexible hose pipe on back side and leave pipe outside room.

You turn the device upside down when winter comes :D

The sound reminds me of two things.. a vacuum cleaner and a jet airliner.
it does do its job though XD

good idea! you must find a way to install the switch outside the box so it will not cause moisture inside the switch, just to be careful.
Very good, thanks for you ( from Indonesia )

Man that thing screams. Awesome job.
Bro temperature sensor is reading temperature inside of box... Connect sensor outside so u can measure surrounding temperature
Yeah..i just consider about it bro.. The same question with you..
he mean home for ants
The room temperature should increase. The front cooling should equal to the heat generate at the back.
I have a question. I also made a water cooling Perrier air conditioner, but asap dc fan in to draw the cold air is turned on the peltier temp start to go back up on the cold side . What ami doing wrong?
Instead of using heatsink for peltier, inside, couldn't you use a radiator with closed freon circuit or cooler liquid for car? PLease reply, thx!
yes thatsi think better but what the result we got after then, coz this small project only can cool a doll house room
Why you have not used heat sink on cooled side bro?
my room is present in the center of my house.... i have to keep in to table close to my bed.... there is no window present there for dumping heat outside.... it will work???
peltier need exit to extract hot air
Good work brother
This is probably the best one
Does the plastic body get melt by the heat of the heat sink ??!!
Car me battery par chal sa kata hai kya usb through
Great video, Thank You!
creative!!...👏👏👏
so much more detailed from other videos i have watched. Thank you so much for this :)
Can we use Peltair Module to cool down the cooler water tank water temperature. Is this possible
Hey bro can't I reverse the polarity of peltier to make it a blower in winters??
Please reply
yes u can, just reverse this process
i neef one for my car, please furnish and oblidge
Hi.. wen I tried to connect all the 3 products. 1 peltier, 2 fans.. but the speed of the fan has decreased can some 1 describe how is that possible. Do I need to buy the higher voltage adaptor for this do the power is supplied exactly?
Use 12 volt supply only but carefully calculate the ampere of total, by applying less ampere will slow down the system.
It will be better to use 12 volt 10 ampere supply.

Nice project thanks dude!
whether without water circulation from a mini water pump using waterblock with peltier would not be possible to cool the air to the maximum
Where did you get that sever fan from.
can i make the samller one for bike riding that can be mounted on my helmet
Can it be use in Old cars which come without AC???
Can you tell me how to use it because i am making the same one but it is not cooling that much
Also power consumption ?
Hi bro , 12v 5amph adapter main peltier ka cooling side thora der bad hot ho jata hain. Iska solution kiya hain . pls comments
Very good bahiya thanks
dude can u please give link to buy heat sink and 2.5A Fan. I tried but i cant get it
You will find both in your computer's CPU
Can you achieve the same cooling effect without copper heat sink or what is the difference in temperature gradient
temperature sensore at air outflow and further into the room would be good. For me i would add some insulation in the box or under the box (outside) to reduce the fan noise. I don't think my neighbors would like that sound. I wonder if a duct reducer is on the outside, and using a bigger fan would also work. i think i would prefer using a larger quieter fan, like 120mm or 140mm.
Where did you get that cooling fan from the hot side?
From old server power supply.
Good job Bro I like it
Nice project bro, but you could install another heatsink on the cooling side of the plate, this will help distribute the cold air inside the box.
Nice projects.....
ye cooling module 12v ki bettery pe kam kar degi kya please reply request
Good video.perfect understending.
I like your design...
Muy bueno tu aire acondicionada te felicito lo voy a poner en practica gracias por compartir tu video PULGAR ARRIBA por eso saludos desde ARGENTINA
Will you pease provide the links of cooling fan and the copper heat sink ? Thanks in advance.
Will all the products can be used by a single adapter of 12 v
Yes 12 volt, 10 amps.
Bro where did you get that fan. Can you describe more about that. Please reply
you can collect it from any comp shop or dead computer, cos its a computer cooling fan, the best you can use small radiator which use to cooling CPU
I couldn't find any copper heatsink of that size anywhere, where did you get it?
Which solutions have u used to stick the peltier??
2 part epoxy glue.
sir how long can you run the peltier a/c continuously
Excellent.....
Excellent, please help me, what is the name of gum for fixed peltier , thanks
Where can we get casing box
Where available fan you use??
how many btu's do you think thats capable of? and would it be possible to make a 700 btu ac using tec?

What is that fan for? I couldn't find super powerful fan like this.
Servers.
Good
8:36 the fan will suck air into the unit not blow out the front...
plus this doesn`t make sense.... cooling equals hot side vs cold side, it `s like saying leaving the freezer door open will cool the room
You need to use your imagination and put the hot side outside of the area you are trying to cool just like a window air conditioner or put the hot side inside if you're trying to heat a space. I want to cool my bunny Hutch
Thanks please how can I get some of the materials
Great...What is the life of those peltier modules? And how long can we leave the AC on for?
Keep work brother

Love this fan for my office. Only good if its blowing directly on you. Not meant for cooling large areas.
Can i use ac supply i.e 220v directly to the module
No, only 12 volt supply is used.
How much time i can use it regular
Great n Nice job sir. Can you also show the air direction of the 2 fan? Thank You and God Bless

What kind of glue are you using is that some kind of dielectric something or other? Great idea good video needs sound and words. Thanks Guy Good Luck Good Health to you
can you make the ultra low noise please.
Why you not using other side heatsink
Cold side does not need heatsink necessarily, as air comes from front fan directly meet on cold side condenses much quickly than using heat sink.
Are you sure that the cold side is better without heatsink?
But I think the heatsink " aluminum or copper " will act as a catalyst or a medium; to speed up the heat transfer rate.
Am I correct?
Sitaram bhai yadav 03049953213
nice demo.thanks.i will try.good job.
Bhiya temperature sensor ke pin ko apne peltier ke upar kyu laga Diya hai, iss terah to wo peltier ka temperature show karega but hame to room temp kam hote hue dekhna hai.
Temperature pin, Peltier pr lagane se ye idea hota hai k after condensation temperature kitna lowest degree maintain horha hai.
Namee(moisture)kaisay kum ho gee? Namee Barhatay gee tau hubs ho jaega.
dangerous innovation right
That means you are saying 15 deg cent is the temperature of the air coming through the outlet of your device right?
Use dehuidifier.
excellent concept but a bit noisy. Also you appear to be reading the temperature inside the box while a reading at the outlet of the box would be more appropriate. How much power do you use. I hear peltier are only around 5% efficient.
Is that room temp?
very good demo. Thanks for sharing.
Can you please share where you have sourced copper heat sink and powerfull fan?.
I wish to do the same to cool helmet.
You can search on local computer scrap shop or also available online server cooling fan 12 volt 2.5 amps.
Can it cool a room ?????
what kind of fan on copper you use please
12v high speed fan
nice build
What about the condensation from the cool side?
Love your project :)
Where does Hot air to discharge? Within room???
Kitna time cla skte h
Yoy should connect one another heat sink in cool side of the peltier. You shuold not use so powerful fan in heating side to reduce its noise
What job the out fan ? I see that many are doing it. But is the Module not hot with the external fan?
Is there datasheet to follow how put cables together
The idea is there people it’s up to you to improve and one question does water drip from cold side or not?
It seems you used metal box not plastic box. However I find here few technical issues: (1) What's the max. temperature to be safe for this Peltier unit? (2) How long we can continue the unit at a stretch? (3) There is no heat sensor circuit to cut off the power supply after getting desired temp. or any delay circuit to protect the fan and other parts.
your gettimg only the temperature inside the box...thats why its easy to get cold .how about temperature ambient the room does it get cold?
It can reduce temperature of small spaces like mini camping tents. Or it can be used as desk cooling fan by adding a flexible hose pipe on back side and leave pipe outside room.
Is it safe? If I use a 30A power supply
Bro one doubt.....wont that plastic box melt because of the heat emitted by the peltier????
The heatsink fan is good enough to remove heat, but very loud
Can I use 12v 1a for this please reply fast
No, these are 6 ampere peltier, not work on 1 amp.
How if i use power supply 12v 30 amp?can boom???
sounds like an airplane about to fly
sounds like f22 fighter hypersonic
