*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.*
#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👍
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.
Not Funny Sir but the translation is not the problem. It’s the numbers he gave. So He lied.
More of an improper space cooler
Longest comment I have ever seen!
Man that thing screams. Awesome job.
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
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.
Have you completed yours ? Can I see the picture/video!?
@@shahrukhansari2006 Wlll get back to you. Working on so many projects right now I need to go back and read the thread. Thank you for asking.
You turn the device upside down when winter comes :D
I like
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.
Very good, thanks for you ( from Indonesia )
nice demo.thanks.i will try.good job.
Great video, Thank You!
Love your project :)
Good video.perfect understending.
Nice project thanks dude!
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。
The sound reminds me of two things.. a vacuum cleaner and a jet airliner.
it does do its job though XD
@Dave Muffoleto, look !...if you smart then you should overcome it, give us all solutions not just complaining about it ...
Exactly😅😅😅😅
Also Air Blower

sounds like an airplane about to fly
sounds like f22 fighter hypersonic
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.
Yes
This is probably the best one
Good
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.
I like your design...
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.....
Excellent
so much more detailed from other videos i have watched. Thank you so much for this :)
Keep work brother
Very good bahiya thanks
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.
Excelente.....
You need to add heatsink on cold side and cut up some aluminium cans and jam in slots on heatsink to increase fin size and maximise air to cold surface contact area just like a real AC uses an evaporator. Also, water cooling hot side works better with salted water.
nice build
creative!!...👏👏👏
I couldn't find any copper heatsink of that size anywhere, where did you get it?
thats a good idea
Like it., sir. Thanks.
Good job Bro I like it
Excellent.....
im tecnition also electrical mecanical ielectronics all rounder man but isee many peoples better then me i love for all any one
ได้ความรู้ดี
Coloque um Peltier em cima do outro e ligue em série, vai abaixar o nível de consumo e melhorar a eficiência.
Great...What is the life of those peltier modules? And how long can we leave the AC on for?
Good work brother
Love this fan for my office. Only good if its blowing directly on you. Not meant for cooling large areas.
Nice
Thanks.
whether without water circulation from a mini water pump using waterblock with peltier would not be possible to cool the air to the maximum
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.
WoW really wow, my friend thanks for sharing this video with us, and other than it's super cool cool air, it's the first very good looking AC I've ever seen really it's very good looking powerful AC, thanks again bro, bye for now.
Do you know that an peltier produce more heat than cold
3:34..It feels like I traveling on an aircraft
ye cooling module 12v ki bettery pe kam kar degi kya please reply request
Where did you get that sever fan from.
Best video
very good
From were you got that jet fan. I want it sir
Will you pease provide the links of cooling fan and the copper heat sink ? Thanks in advance.
This is typical window type AC were wall mounting will give barrier between hot and cold hot side needs to be cooled faster to get real cooling affect
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?
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
Hi bro , 12v 5amph adapter main peltier ka cooling side thora der bad hot ho jata hain. Iska solution kiya hain . pls comments
Pls replay with what component and things u used for this
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.
Great n Nice job sir. Can you also show the air direction of the 2 fan? Thank You and God Bless
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
I would place my peltier module on a ceiling... I just like to know if which one is more efficient compressor or thermoelectric... Which one doesn't consume much electricity... Which one is durable...
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 am peltier module for laptop cooler from bottom side ....yes it works for decreasing more than 9 degree on medium gaming...
Please talk more in this video I have questions about the glue are Direction Hot Side cold side. I enjoy dish and may try to build one myself but I need to know where the parts come from to. Take care good health to you sir.
What about the condensation from the cool side?
can i make the samller one for bike riding that can be mounted on my helmet
The idea is there people it’s up to you to improve and one question does water drip from cold side or not?
Can you achieve the same cooling effect without copper heat sink or what is the difference in temperature gradient
The noise 🚀🚀🚀🚀🚀
a smaller fan or thinner fan with lower volume flow less noise and power is marginally slower only , to reduce heat. see for yourself. 1 deg celsius maybe compared to a large fan. the bottle neck is the surface area of your cooling fins not you fan size. same rule applies for car air conditioning . heat transfer is a function of time at slower air flow speed being more efficient to allow for heat transfer. that's why cranking up the fan in you car as you get in is counter productive to cool down the cab.
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?
Excellent, please help me, what is the name of gum for fixed peltier , thanks
Great for a deaf person :)
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.
Gives air cool?
Can it be use in Old cars which come without AC???
how many btu's do you think thats capable of? and would it be possible to make a 700 btu ac using tec?
Sundar
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.
*In your case, you use a fake copper radiator And a very very loud server fan... The best option is: 1) use the radiator on the" hot "side in 3-5-10x times more than on the" cold " (look among the old spare parts), the larger the radiator, the slower the heating will go, and you can put a quieter cooler for cooling*

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?
Does the plastic body get melt by the heat of the heat sink ??!!
BHAI 12 P.C WALI 12 VOLT POWER SUPPLY KITNY AMPEAR KI LAGNA SAHI HY 6.AMPEAR YA 10 AMPEAR MUJHAY YEHI AAP WALA 2 PELTIER TEC1-12706 WALA SET SUPLAY PY CHLANA HY.PLEASE BHAI REPLY ME.THANKS
10 ampere wali supply thek rahegi.
zeeshan faizi app pakistan may hotay hain ya india may
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?
These are 6 ampere each peltier, fan is 2.5 ampere.
No cold heatsink ?
Can you tell me how to use it because i am making the same one but it is not cooling that much
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
Car me battery par chal sa kata hai kya usb through
👍👍👍👍
Very loud but works very good
Where available fan you use??
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.
Put heat sink both side bro
yes good idea, but do u think this can cool ur room like ac? no bro, tbis experiment is like a toy
I wish you did not use those horrible loud 1u rack server fans, it would be a very good idea. Nontheless, it looks nice, but I would choose for air displacement and not small loud fans. Dissapate the heat and the cold by big 120 mm fans would also work, and saves a lot of earnoise in as outside the cooler. There are 120 mm fans that run on 5 to 24 volts, so with some electronics in between, the fans could blow harder when needed... That is how I would like it to be... Good video!!
What is the btu output on the cooling side
nice
Thanks
