this is amazing i have make same to same thank you

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.

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.

This gives me hope that this time, my Perpetual Motion Machine will work.

One of the best non-functional designs I've seen in youtube

This works great for making a mini AC for a cat/dog house. Made one for my cat house. 👍

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.

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!

It will make ur room hot like hell in 10 minutes

*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*

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

That's how my tiny fridge works, nice.

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.

Prevents break ins. This I needed.

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.

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 :=)

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.

Cant believe theres actually someone who uses toothpaste, i thought the toothpaste thermal paste thing was just a joke 😂

This is amazing, also its more like an air cooler and for those people who don't get it, its purpose is to cool the person using it, not the room.

Sadly, the Hotel Air is going into the same room itself.

i made one like this a while ago and keep improving it .it runs on 12v 3amp it cools my 2 bed flat nicely

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.

One heck of an instrumental 🤯

No bakwas... Fully detailed crisp video i have seen recently. Well made project, well presented video. Well done. 10/10

My Air-conditioning system : So should I resign from my Job. 🤣🤣🤣

You have to stick in a Window...to remove the heat outside..and in winter to reverse the project

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!

The wrench 👍

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?

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

Nice work bro👍👍👍🤝🤝🤝

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

My old san ace fan will be so usefull

haahhaah, having the peltier hot side inside the room would actually make the room hotter :P

That will destroy your Peltier unit as you will have hot spots it must be fixed to a perfectly flat surface, not ridges

I made tabletop ac recently with separate heat dissipation unit

It should be install in wall with elongated ducts, and can be reversed in winter season to use as heater. Yoooo🎉 nice idea with lower running cost

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...

A machine without testing and final results is useless

good to see you video video is very good

I can use this in an indoor garden tent!!:)

Ok, I need to you change your design. First of all, you should use a water-cooled heatsink block on the heating side plus a computer radiator that goes outside the window. Just using a fan might damage the peltier module

success for "Pro Know"

a great thing for my gaming pc

this is good for tent

Nice toy for a doll house 😂

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.

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

have you made any documentation for analysis of this project, like temperature relations ????

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.

This is not an air conditioner..what you made is called a just a fan.

Your video looks like the wrench videos 🧐🧐

Perfect cooling how

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!

Ok chill wit the transitions

Bro graduated from kfc😂😂

Thanks for introducing me to LiQWYD - Sweet

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.

Very good

Good job .....👍

please pin it brother.. the work is great.. thanks for the knowledge. greetings from Indonesia💝🇮🇩🇮🇩

nice bro

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

Excellent... Idea...!!!

Good job uncle

Best temperature controller.. Trees..

Did you Checked Temp of the hot side & Temp of the Cold Side. ?

This would go even better with liquid cooled heat sinks.

"Power hungry heater". That thing will only heat the room up.

Wow very good

@proknow I ❤ the design. Inspiring me.

At the end of the day, the room will be warmer with the unit than without. the warm air at the bottom is more that the cold air in the front area..

Sir Aise hi ek pani ki botal ke liye banaye

This is one of those videos that just looks good but has no actual applications, heck the Peltier module and the heatsink don't even have proper contact, this will work as a good room heater though.

Nice

peltier devices drain alot of power cost and it doesnt cool very well.. ive experimented alot in many ways my fridge does more for less of the cost ngl

The holes near the output fan is not required. The heatsink on the cold side should have bigger fins to cool the air sucked by the output fan. The heating side should be kept outside the cooling area.

nicely done, neat job, I also had fun watching the transitions hehe

2.4mil viewers of this channel are hot. GreAt video. Really helps break the steriotype than Indians(dot, not feather) are good at engineering.

In the end this device will heat up your room! Peltier module by it self generate heat beacouse of relativliy huge electricity consumption and very low effinciey. With 60W power supply, more than 90% of that energy will be converted to heat by the module and spread inside room. Great video but this project isn't good.

How "powerful" is this really? That fan isn't going to blow much. Also, you're missing displaying a temperature reading from behind, around the room, and right in the front of the device. I don't think there will be much difference, and you'll probably end up with a net warming of the room. Peltier works for tiny desktop refrigerators, but I wouldn't say for this purpose. You'll be better off just buying any cheap window or portable air conditioner at Walmart.

Whatever! Looks cool!

Even the idiots trying to cool down by opening the fridge door does a better job.

can this project cool down a single person tent . I will keep out the hotter side out.

unless you have tv size Peltier and a nuclear power plant at your back yard.. Lol. But good science project.

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!

This would work nicely in a truck cab if it was mounted so the rear was outside the vehicle. Maybe through the firewall.

Owsome amazing idea

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

While the design is garbage it does give me an idea...

Great project, note too much thermal paste isnt a good idea. Just need a paper thin layer.

make one with R410A refrigerant

Datasheat calls for 140psi to show correct temperature chart . It's way more efficient at 140psi .

one site crazy hot anoter just chilld

There's a new way I just uploaded. It doesn't use a lot of power and requires water.

Wow.... Amazing idea👍👍👍

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...

Good job my friend 👍❤️🙏🙏

Good, but there will be needed a pipe that blows the hot air outside.

great project but a water cooling system instead of fan cooling is makes it more efficient
