How about using it as summer non stop AC. My idea which I may make soon is installing the peltier on room window where the hot side is outside the room and cold inside.
A personal cooling device maybe. You may replace both mini fans on cool side for 2 large CPU heatsinks placing the fins side inside a tube or similar structure frame to create the air path. A 30 cm or so propeller fan at the end of the tube will move the air and blow on you face/torso.Onother tube on hot side will blow the heat through a window outside the room.
I will use the same unit to help the basement wine cabinet (up to 200 bottles) stay below 55F in Colorado summers. I use a small garage heater and an Inkbird Pro controller for regulation. The Inkbird is web enabled so I can track wine cabinet temperature remotely.
I know this is a old video but I just purchased a large TowerOfPower Humidor Cabinet. I live a warm area and running the AC is far too expensive now. Making sure that the inside must remain 70° humidification is not hard since there are many devices to purchase to maintain that 70°. What there is not, is a unit or product to maintain the 70° inside temperature. Wondering if this would be a option with a Temp control module would do the trick.
Just to point out, a large drawback of peltiers is their low efficiency. It can be used for hobbyist/small projects but can't replace air-conditioners/coolers meant for larger area coverage as solicited by many of the comments.
Ketan Vaidya actually it can. Their efficiency is bad due to the amount of power input and the energy lost to heat. Places where electricity drain does not matter, such as if you go on holiday in a hotel, you don't care what their bill is. Same as industrial places,
The efficiency of a regular fridge is between 40% and 60% and the efficiency of a peltier module is between 10% and 15% so very inefficient indeed. They are mainly useful in applications where there is no room for compressors, pipes, liquids and gasses and in cases where the orientation of the system is changing a lot.
They can be good if you flip direction and use as heaters for batteries(lead acid on solar system in well insulated shed), or keeping a water bowl thawed in winter...
I live in mexico and love to go camping with my gf, BUT theres a huge problem... the insane weather!!! imagine ur in your camping tent at midnight WITHOUT heat and those mosquitos, would actually be heaven, also if u add a 12 v solar powered system u can easily get inside ur tent and watch comfortly a movie with someone, ( i know that thats not the point of going outside) but it would be really fun !
AC 0.5 HP is 500 to 600 watts, u have the right idea just cool the bed space.... BTW u can always use the hot side for dry heat sterilization, great for table utensils kitchen utensils
You can add a water block probably an alumini or copper made in between the peltiers and than run cold water through it which gets criculated in cheap copper pipes which can than be mounted on a table fan this way the efficiency will be much increased also there will be condensation of moisture in room leading to Air conditioned effect ...alternative to water can be an anti freeze coolant which ll be bit costly but more effective than water...no need for heat sink on cooling side just sandwich the peltier module onto the water block ....i have tried this is works perfectly i used 2 peltiers on laptop chargers almost 100 watts bt it gives me cooled air one more modification can be that you can use some tubing made of cardboards with inner side covered with alumini foil or tape to vent out the hot air...or else the cooling and heating simultaneously will nullify each others effect thanks
What about using water for cooling the hot side and the cold side for cooling water which will pass thru a fixed fence which you can use with any regular fan to cool any area.
Are the interior fans really necessary especially if using a big heat sink like the one outside? In that case, convection should take care of the chilling.
I have what appears to be the same unit. Where did you get the wiring diagram? Do you think its enough for a small wine cooler? I need to get it from about 68 to 5oish farenheit?
It's just positive and negative, 12V supply. So no real wiring diagram is needed. As for whether it could be used as a small wine cooler. Honestly I'm not sure. I guess it should be possible, since many mini fridges only have one of these cooling units (peltier)
I just bought a unit nearly identical to this one. Mine has the same fans and heat sinks, but mine has 3 modules instead of 2. I wanted to use it to cool a bedroom. It hasn't arrived from China yet, so I won't get to mess around with it until then, but it is supposed to tolerate 150 - 180 watts on the high end at 12 volts. What's awesome about them is how small and compact they are. If 1 unit isn't powerful enough, I could stack another 1 or 2 with it in the window and get additional power supplies for them. If it's simply too weak to accomplish anything in my window, I'll make a foam box for it and use it as a mini fridge hahaha.
again....5% efficiency on peltiers. ur in for a huge let down if u think u can cool a room with these...even if u properly insulate the indifference of temperatures. u could get box fan for the same price i bet
nautical1983 box fans don't make a significant temperature change. I bought one to mess around with it. I may incorporate it in my computer some way if it doesn't help my room at all. I bought it to mess with it and if it's super inefficient, I'll run it off solar or I won't use it as an AC. I just find it to be an exciting concept. No moving parts. Very cool. I'm also interested in the efficiency differences if you is more units at lower power instead of fewer units at maximum power.
OK so, I don’t know anything about Peltier modules. But, the other day, I blew an old mini fridge because, when it was manufactured, they used the same socket for 12v that one would use for 120v so, I didn’t know the difference and blew it. One of the engineers I work with took interest and said that it probably had a Peltier module so, I gave the fridge to him so he could tinker with it and bought myself another mini fridge, which might also have a Peltier module, but cools as well as warms. Anyway, the question I’m trying to get to is whether it’s possible to convert an Homedics MyChill from an evaporative cooler to one with a Peltier module. I have 2 MyChill units (one large and one small) and, apparently, Homedics knew little about how to manufacture what they were selling. I’ve had both for about 3 months. The larger one will no longer distribute water and the smaller one, which I keep at work, is leaking water all over my desk. But, I’m looking at the size of what you have, I wondered if something half the size of that could be used inside of an Homedics MyChill, without all of the problems the units ship with. As the new mini fridge I purchased, apparently, uses not much more electricity than a light bulb, it seems like a perfect match, although from what I hear regarding most Peltier setups, they seem to draw too much electricity for the benefit. Still, I would love to have a small, portable, leak-free unit for home and work. Is this a possibility at all?
How about a cigar humidor? I need something like this to maintain the temp of 65 to 70deg. I have a tower humidor about 6ft tall but narrow. I also need to convert that to a regular plug.
im also planning same thing as you think.It has a dimension of 1.5x1x1(lxwxh).I hope you can justify if using peltier is efficient compare to regular AC using the same amount of power.
I regret I did not see this earlier i spent some good money on a Corsair water cooling for my PC this Peltier Cooler seem like the perfect solution to cooling my entire CPU tower.
you should be happy with your purchase. a peltier is an open source of differing heat, thus creating condensation as apposed to closed water systems. arc ur ecu and ur out more cash with potential fire hazard. i work at microsoft and have heard its a bad application
It is a bad application because those peltiers consume a lot of power that is also converted into heat. You will have to get rid of that extra heat as well.
I live in my 1991 ford f150 with no real ac in the flat bed with camper top. As window ac units are just too big. I would like to see this cooling a space 8’x 5’ x 5’ as i have a 12v supply. If it worked it could be mounted in the sliding side window.
I sleep in my truck and need cooling. Pick up trucks have a sliding rear window that could accommodate something like this. Would love to work with you putting something like this together.
I'm looking for a little help.. I watched a bunch of videos on these and not getting a solid answer and it seems you are the only one that actually responds to questions. OK here it goes. I built a 1:32 scale "ice box" for a model ship. I used the smallest Peltier module I could find with the lowest volt requirements. ( TES1-3103, 3.5V/3A) I'm powering by a 3.5V 1400mah li-po. The unit seems to work but it gets very hot pretty quickly, no matter the polarity. what am I doing wrong here??? do I need a buck converter?? or are there different peltiers for heating/cooling? STUCK!....
Randy Coolbaugh i think peltier modules logic is The lower the temperature you can get on the hot side, the lower the temperature you can reach on the cool side could be upto -0 to -35°C depending on the type of peltier module.
oh. so the TYPE of module also depends on degree of ability... did not know this! Thanks!! I have been playing with this thing for a bit, I ended up making a larger heat sink with a fan.... a teeny tiny fan.... also I installed a buck converter... This is as much as I can do without it loosing its scale ice box appearance.
"that" thing will draw 4-5 times more watts than the conventional compression AC while doing the same "cooling" essentially if you wanted to achieve the performance of an 800w AC you would need about 4000w worth of peltiers, and the heat those will produce will be around 7000w, imagine that, how would you dissipate 7000w of heat? anyway im just thinking of making a personal AC with this, since going down the scales that much you simply cant do it with conventional AC units, and using around 200-300w to cool your face on a desk seems pretty reasonable to me
I want to use this to cool a small space for my kid's chinchilla during the hot summers. How far below the outside temperature do you think this cooler will keep a 2x2 ft box. If its 100F outside, do you think it would keep it at 70F?
Great video, thank you. I'm building an insulated dog kennel and thinking of installing one with a solar supply to keep my dogs cool during the hot days - I don't know much about these peltier coolers, is it likely to work? Kennel will be 1.8m x 1.2mx 1m high...
Just received the exact unit as u.. I thought the bigger fan was the cool side... What a led down knowing its not... If u exhaust the hot air out do u think it will cool a room down?
would make a good retro fit / repair kit for failed RV refrigerator.. how cold can it get ?? 22F ?? for freezer and 38 F ?? for fridge ? how hot is the exhaust ? Thanks
How about using the heat energy instead of letting it waste. Does it get hot enough to boil water? That could be used to run a steam motor while still getting benefit from cold air.
I’ve made a dual peltier liquid cooled water chiller, with the water(hot side) in a closed loop with no cooling the 100ml water reaches boiling in 10 minuets and after 20 min the pads have overheated and destroyed them self Water on the cold side (10gal) will reach 5c from 24c in 8 hrs
the goal is to keep the hot side on its optimal temperature or else it gets broken... It was our thesis when I was still a fifth year student and we figured it out after 3 broken 12706 peltier plates... so yeah such a waste
I´m on a middle of a project which requires using peltier modules. I am planning to use a 12 V battery car to power 8 peltier cells. The battery will be connected to the car´s alternator. I have a small van with no AC, still thinking about the best way to install the complete device. I hope everything goes right.
Gadget Addict I want to use it for cooling, where I live weather is not extreme, winters usually don't go below 11 Celsius but summers can reach 33. I haven't been able to find too much info about powering multiple Peltier cells using a 12 DC voltage from a car.
I was researching this for a tiny cat house I have, any suggestions for a better power option? I would like to heat and cool it since I'm allergic and can't have the cats inside they stay on my screened in porch.
Nowadays you can actually buy small portable aircon units which look almost like a slightly oversized brief case. Or maybe between the size of a brief case and the size of a carry-on luggage. They're proper condenser based aircons, but just made much smaller. Those would work well, at least for the cooling side of things, I'm not sure about the heating.
I had a look at your video and thought why not make a personal food chiller or a chilled water cooler for drinks. If it was a mobile you could also use it for camping.
Hey dude! Great video! My bedroom reaches 32c and is ridiculously uncomfortable to sleep in. I have a 400mm x 400mm x 300mm polystyrene box with a lid... if i cut out a square hole in the back of the box, mounted this unit so the small fans blow into the box, place 2x 120mm 2000rpm fans in the other side, what kind of results do you think could be achieved temperature wise? I know its a "how long is a piece of string" question.... thanks :)
Sir, you seem to know what you are talking about. Got a question for you. I have a 12v koolatron p25 thermoelectric cooler. I was thinking of running a duct from one of the car's ac vents outlet to the lid's air intake so that it will have a colder temp inside. Could this hack damage the unit in any way? Thank you
I wonder if you mated this with a bed mosquito net if that would keep the cool air localised to the bed area ? Need to be sure the heat sink doesnt ignite the mosi net 🔥 You could also make a solar powered cooler box
hi mate...im confused to my project...i wanna ask you each item like fan and peltier 12v...then you join the wire all before connect to power supply.i saw your power supply 12v,is it ok??
One fault I can say with these is the freezing up of the cooling side leading to freezing the fan therefore making the cooling ineffective. To improve the item needs bigger cooling heat exchangers and a bigger fan which sits below not touching the frozen cool exchanger
Is there a way to control the cooling strength? Like your FLIR showed 16 deg, could it be set to draw less power but output 23 deg instead? BTW, it was kinda awkward at the end you were moving but had the two "previous" videos show up. I think it is much better if you just froze the last frame instead. :)
How many peltier that i need to make cool 2,5x2,5 m with 3 m ceiling? I live in tropical country summer is the worst. Air conditioner consume a lot of electricity and the price is expensive. I want to make one by myself.
There's probably some math behind working it out but I'm not sure. You'd need a LOT i'd guess. You might want to look into converting a car aircon system instead.
Titoyan Dwihandoko ohh its the worst summer then less then 25 would be usel3ss and btw one peltier draws 70 watts 70x25 equals more then 1300watts which is the same as air conditioner lolz
why not put a chunkier heat shield. a cool coffin-like pod seems to be a good idea. I wonder how many of that thing you're gonna need to properly cool a pod.
Water Chiller, Reservoir and Pump for a chilled water quilt, using 1/4 inch poly tube snaked though 2 bed sheets stitched together(like cool suits racecar drivers use).
Hi, Can you dip the heating part into water without the fan attached ? Peltiers are anyways inefficient, so want to know what impact that experiment would have on cold side of the module :-)
Yes you can. I read from a guy that actually dipped it in a large bucket with a lot of icy water and the temperature of the cold side of the peltier got down to -50 degrees Celsius. The maximum achievable temperature difference of both sides of the peltier module is 67 degrees Celsius, so if you manage to cool down the hot side very well the cold side will get very cold.
hi buddy, I am very much looking for air-conditioning solution for my 60 bed hostel using a peltier design, the reason for this is fairly simple 1) want to just cool the bed instead of the whole room 2) I could have duct free AC solution (I had considered using an old 1.5 ton AC via 2-4 inch ducts to supply cool AIR to all the beds but that would mean running the AC all the time irrespective of bed occupancy) 3) I am using wall fans right now which use 60 watts of power at 230volts whereas this will be using 12volts at 60-80 watts hence similar power usage *(hopefully) however I foresee 1-2 major challenge 1) Dissipation of Heat - Generation of heat from the peltier heat side. Possible solution - I could use a liquid cooling method & circulate the water through an over head tank with 60 units running all night for 12 hrs it should be able to heat sufficient hot water for bath OR atleast warm it 2) I would still be left with the problem of recycling the AIR in the enclosed area. 8hrs of a person sleeping in an enclosed space is unhealthy & dangerous therefore I would still require ducting system for this question to you - have your observed the time taken to the cool the enclosed bed space that you had experimented & also how much temperature drop was possible
Hi, hope you can do review of power saving devices that can really benefit regular power consumers. I like how you do your test. Very intrigue with them such as plugin capacitors and those that are like stick ons like the surich scalar energy saver. Thanks!
It's available worldwide since it ships out of China/HK. You can find it on eBay, Ali Express and other similar websites. You can find it be search for: DIY double fan Thermoelectric kit. I think it sells for around 20GBP / 25 USD / 1250 PHP.
Just lower the voltage to decrease the heat pumping effect. You could also use a thermostat which switches on at one temperature and off at another temperature, but changing the voltage is better for the peltier module.
Reverse Engineer it! Get the Peltier and put them on the roof to generate a generous amount of energy and save it like in powerbanks or use with a 5V or 12V fan. Hhmmm What do you think? There are tons of detailed guides on how to make one online. It could be helpful at least to save a few bucks.
hey i like your videos! i recently been tinkering with 2 peltiers i ordered on amazon for cheap. they worked great for a little but but both suddenly stopped working. i cant find any info why i destroyed them as i made a diy mini cooler. they were rated at 12v and had them hooked up to a golf cart battery thats 12v. i had heat sinks on both sides. but im confused on the direction of the cooling fans on both sides....i think i had both fans inward to push air through the heatsink and push the temperatures off of the radiating aluminum. the seller was awesome and sent me free replacement peltiers....but im hesitant to ruin another pair of them when i dont have money to buy more. any suggestions where i went wrong? do you know if a peltier gets destroyed if its internal temp destroys itself by not using heatsinks with fans and thermal paste?
I don't think it makes a huge difference whether your cooling fans are pushing or pulling. Peltiers can fry themselves if they get too hot. I've lost a few due to overheating. I've also had some that just failed for no apparent reason. Not being pushed very hard and suddenly they just stopped working. So I guess to some degree it might just be the nature of the beast when it comes to cheap eBay electronics :P
I appreciate the response! I tried to look deeper into it and took a long time... the conclusion I came up with was to start at the beginning . knowing the seabeck effect and its properties to interconnect 2 different distinctive metallic properties and individual conductivity of the unique properties. Then tried to think of where the system could possibly fail...boiled down to the connectivity of the conjoining of the 2 metals. poor welding or soldering jobs can oxidize with air pockets or cheap materials becoming brittle by the high intensity and expansion/contractions by a direct connection with fluctuation of heat. like concrete getting breaks and crack from extreme weather.
You can use solar panels to power those peltier modules to make an airconditioner that does not cost anything for power which would be especially useful during summer. You can then use the hot side for heating drinks lol
the cardboard box. do that but out of plastic or something with a smooth surface. remove the 2 fans on the coold side. make 2 hole's in the box. get 2 metal tubes. short ones. maybe something like what they use for small vents. now you got a intake and outtake for air. put 1 of the fans you removed in the end of one of the metal tubs. now it will suck air in to the box .cool it down then blow it back out. if you have a smaller diameter at the outtake then the air will compress a bit and get colder. (inntake big outtake small) . on the hot side. remove the fans. take a metal tube cut it in about half on the long side. stick it to the hot sides heatsink. and but a fan on one end. blowing air in to the tube. this should create a "vacum" and pull the hot air with it as it passes the hot heatsink. now you consume less power. sorry about the poor spelling and gramer. am both lazy and dum. :)
THANK YOU! lets hunt them all down, and kill them dead! their doing utube a disservice! god the suffering i have had to endure trying to get an education.
Anime fan. Building a Totoro mascot costume that can get up to 140*F inside during the summer. So yeah, I don't dare wear it during the summer. But if you can figure out how to get one of the mini refrigeration units to work in a mascot costume using just a phone battery pack, you'll have some buyers, fast. The one in this video is too large. But I know they make smaller ones that are powerful. Mascot fans work off of a simple battery. But it's not enough. Just circulates the hot air around the mascot costume. You figure that out, make sure the emissions are non toxic, I'm first in line to buy!
maybe you can do a aircooler style that blows cool air to your face or body? icebox then the device on the right side and airblows out to you on the left side... so that device is cooling a little area instead. good airflow for the person...
It should work pretty well. Although I still like the idea of a fully contained area around your body that keeps all the cool air in. But that's starting to sound like a coffin lol
Gadget Addict i think thats good use the one they use to insulate ceiling that looks like a foil with foam so you can roll it up if you want to go out of the coffin hahaha
How many BTU/Hour of cooling will it do? I have done a bit of math and a high-end gaming PC will produce 2,500-4,000 BTU/Hour. The 4000 was a bit of an exaggeration. I am sure that peltiers could be used for PC cooling at very low cost if solar powered.
TEC1 Peltiers are usually in the region of 100-200 BTU so you'd need like a dozen of them to even come close to removing the heat of a gaming PC assuming you were effectively removing the heat to an external environment.
hmm... low cost AC for japanese capsule hotel-like bedroom... not a bad idea G.A... or maybe a smaller one for Mr. Black's new condominium unit perhaps.
lol it's funny you should mention that. I was actually thinking of adding it to the cat condo, even if it's just for the sake of a video. It would be a bit pricey to run 24/7 but it might make a fun experiment and an interesting video at least.
How about using it as summer non stop AC. My idea which I may make soon is installing the peltier on room window where the hot side is outside the room and cold inside.
A personal cooling device maybe. You may replace both mini fans on cool side for 2 large CPU heatsinks placing the fins side inside a tube or similar structure frame to create the air path. A 30 cm or so propeller fan at the end of the tube will move the air and blow on you face/torso.Onother tube on hot side will blow the heat through a window outside the room.

I use mine at 21C for kombucha. Also you can use it for fermentation projects. MIso projects made with koji rice. 6 months to a 12 months fermenting

you can grow a grape or weed plant indoor that demands cold weather with matching Purple Lights for plant :)
hello! are you using this for colder temp plants? i need help...
Just to point out, a large drawback of peltiers is their low efficiency. It can be used for hobbyist/small projects but can't replace air-conditioners/coolers meant for larger area coverage as solicited by many of the comments.

Ketan Vaidya ji, yes you are right. Peltier cooling area is mere 4cm x 4cm that is not sufficiet for cooler or ac purpose.
The efficiency of a regular fridge is between 40% and 60% and the efficiency of a peltier module is between 10% and 15% so very inefficient indeed. They are mainly useful in applications where there is no room for compressors, pipes, liquids and gasses and in cases where the orientation of the system is changing a lot.
They can be good if you flip direction and use as heaters for batteries(lead acid on solar system in well insulated shed), or keeping a water bowl thawed in winter...
can this work for a terrarium of 55 liter size (basically a plastic box im using for acclimmating imported rare plants) ?
BRIGHT IDEA FOR COOLING A SMALL VOLUME IN YOUR ROOM. WHAT DO WE DO WITH THE HOT AIR?
I live in mexico and love to go camping with my gf, BUT theres a huge problem... the insane weather!!! imagine ur in your camping tent at midnight WITHOUT heat and those mosquitos, would actually be heaven, also if u add a 12 v solar powered system u can easily get inside ur tent and watch comfortly a movie with someone, ( i know that thats not the point of going outside) but it would be really fun !

What about using water for cooling the hot side and the cold side for cooling water which will pass thru a fixed fence which you can use with any regular fan to cool any area.
I also tried to make a mini airconditioner but no success yet. I also used a cardboard box with one peltier device.
Are the interior fans really necessary especially if using a big heat sink like the one outside? In that case, convection should take care of the chilling.
Maybe, maybe not. Either way they take a minute amount of power compared to the peltier modules so it's probably not even worth worrying about.
I have what appears to be the same unit. Where did you get the wiring diagram? Do you think its enough for a small wine cooler? I need to get it from about 68 to 5oish farenheit?

Very unique idea. I guess that would work :)
Loved your presentation. Could you please clarify me about 12v vs 5v peltier device performance? Thanks a lot.
im also planning same thing as you think.It has a dimension of 1.5x1x1(lxwxh).I hope you can justify if using peltier is efficient compare to regular AC using the same amount of power.
wow your crocodile clips are way too close put a rag between them they will short out
that's what i was thinking.
That unit is 1/5th of compressors efficiency. To match an AC that is 800W with average 50% efficiency u will need about 60 of those Pettier unit.
can it cool down the water ?
I regret I did not see this earlier i spent some good money on a Corsair water cooling for my PC this Peltier Cooler seem like the perfect solution to cooling my entire CPU tower.
you should be happy with your purchase. a peltier is an open source of differing heat, thus creating condensation as apposed to closed water systems. arc ur ecu and ur out more cash with potential fire hazard. i work at microsoft and have heard its a bad application
It is a bad application because those peltiers consume a lot of power that is also converted into heat. You will have to get rid of that extra heat as well.
How is you voice so calming? You have such a relaxing voivce
I live in my 1991 ford f150 with no real ac in the flat bed with camper top. As window ac units are just too big. I would like to see this cooling a space 8’x 5’ x 5’ as i have a 12v supply. If it worked it could be mounted in the sliding side window.
Could i use this for cooling a mining rig inside a grow tent?
Can we use in car ? To cool off inside a car ?
Could be a back up cooler, manufactured and attached to top of fridge exterior cabinet to keep things cool until repairs are made.
Do you know if this will work with a powerbrick and how to connect it
I sleep in my truck and need cooling. Pick up trucks have a sliding rear window that could accommodate something like this. Would love to work with you putting something like this together.
Test in a two person tent with a deep cycle battery. How long and cold it goes.
It can't cool that much area especially with body heat. If he kept his hand in the box for 5 minutes it would increase the temperature 20C
Do u think this peltier will cool a 250sqft room if I exhaust the hot air out of the window?
I'm looking for a little help.. I watched a bunch of videos on these and not getting a solid answer and it seems you are the only one that actually responds to questions. OK here it goes. I built a 1:32 scale "ice box" for a model ship. I used the smallest Peltier module I could find with the lowest volt requirements. ( TES1-3103, 3.5V/3A) I'm powering by a 3.5V 1400mah li-po. The unit seems to work but it gets very hot pretty quickly, no matter the polarity. what am I doing wrong here??? do I need a buck converter?? or are there different peltiers for heating/cooling? STUCK!....
Randy Coolbaugh i think peltier modules logic is
The lower the temperature you can get on the hot side, the lower the temperature you can reach on the cool side could be upto -0 to -35°C depending on the type of peltier module.
oh. so the TYPE of module also depends on degree of ability... did not know this! Thanks!! I have been playing with this thing for a bit, I ended up making a larger heat sink with a fan.... a teeny tiny fan.... also I installed a buck converter... This is as much as I can do without it loosing its scale ice box appearance.
Also if you bought it from China, it is quite likely that the module is simply broken. In that case it will just short circuit and heart up.
really!?... yah, that would be just my luck.. never thought that as a possibility. THANKS!..
Hey I just suffered a raspberry pi overheating burn due to over clocking, So I recommend it to use for that.
Yikes. I'm surprised to hear that. Did you add heatsinks?
"that" thing will draw 4-5 times more watts than the conventional compression AC while doing the same "cooling" essentially if you wanted to achieve the performance of an 800w AC you would need about 4000w worth of peltiers, and the heat those will produce will be around 7000w, imagine that, how would you dissipate 7000w of heat?
anyway im just thinking of making a personal AC with this, since going down the scales that much you simply cant do it with conventional AC units, and using around 200-300w to cool your face on a desk seems pretty reasonable to me
I want to use this to cool a small space for my kid's chinchilla during the hot summers. How far below the outside temperature do you think this cooler will keep a 2x2 ft box. If its 100F outside, do you think it would keep it at 70F?
Great video, thank you. I'm building an insulated dog kennel and thinking of installing one with a solar supply to keep my dogs cool during the hot days - I don't know much about these peltier coolers, is it likely to work? Kennel will be 1.8m x 1.2mx 1m high...
Its been a year since you posted this. Did you ever build one for your dogs? Id like to do that too
How much better would it cool if you used a cpu liquid cooler closed assembly?
Just received the exact unit as u.. I thought the bigger fan was the cool side... What a led down knowing its not... If u exhaust the hot air out do u think it will cool a room down?
No way.
would make a good retro fit / repair kit for failed RV refrigerator..
how cold can it get ?? 22F ?? for freezer and 38 F ?? for fridge ?
how hot is the exhaust ?
Thanks
If can it get hot enough to distill some amount of ethanol, maybe try that and use the cool side for condensing the vapours...?
I think you can integrate the device to bladless fan and directly get cold air.
+jeyeckumar swaminathan perhaps. That's an interesting idea.
How about using the heat energy instead of letting it waste. Does it get hot enough to boil water? That could be used to run a steam motor while still getting benefit from cold air.
It can boil water but I'd imagine only small quantities at a time.
I’ve made a dual peltier liquid cooled water chiller, with the water(hot side) in a closed loop with no cooling the 100ml water reaches boiling in 10 minuets and after 20 min the pads have overheated and destroyed them self
Water on the cold side (10gal) will reach 5c from 24c in 8 hrs
just freaking yell and say you're gonna take stuff away! I'm about to FLIP!!!--
the goal is to keep the hot side on its optimal temperature or else it gets broken... It was our thesis when I was still a fifth year student and we figured it out after 3 broken 12706 peltier plates... so yeah such a waste
That unit can be used to convert ice boxes on boats and RVs into electric coolers at a fraction of what traditional Refrigeration costs...
hi try to reverse the polarity on the Peltier's and the cold side fans and use it to cool a room like a 12v air conditioner.
The peltier will burn within minutes because the hot side will be getting far too hot.
I´m on a middle of a project which requires using peltier modules. I am planning to use a 12 V battery car to power 8 peltier cells. The battery will be connected to the car´s alternator. I have a small van with no AC, still thinking about the best way to install the complete device. I hope everything goes right.
What's the purpose of the device inside the van? Are you using it for cooling or heating?
Gadget Addict I want to use it for cooling, where I live weather is not extreme, winters usually don't go below 11 Celsius but summers can reach 33. I haven't been able to find too much info about powering multiple Peltier cells using a 12 DC voltage from a car.
I was researching this for a tiny cat house I have, any suggestions for a better power option? I would like to heat and cool it since I'm allergic and can't have the cats inside they stay on my screened in porch.
Nowadays you can actually buy small portable aircon units which look almost like a slightly oversized brief case. Or maybe between the size of a brief case and the size of a carry-on luggage.
They're proper condenser based aircons, but just made much smaller.
Those would work well, at least for the cooling side of things, I'm not sure about the heating.
Hi did the kit comes assembled ? Because i ordered one
Yes it was already assembled on delivery.
Hi.have you ever tried to dip the peltier into a water and see what gonna happen is the water will boil first or freeze first..
+Jan Francis Bagadiong it would boil first. It generates much more heat than cooling.
Gadget Addict "oh see thanks. Im getting curious what more these peltiers can do.
I am looking to cool a big water tank, what would be the best idea?
It will take a long time to cool a big container
(That's the second law of themodynamics)
So you need a big module of peltiers and a lot of power
I had a look at your video and thought why not make a personal food chiller or a chilled water cooler for drinks. If it was a mobile you could also use it for camping.
I plug it to a power suply, or a temperature controller???
I have been looking at this same cooler to cool a small bathroom. Now I really want to get one to try it out. Thanks for the vid.
Won't work because of low efficiency.
Can i cool water in large chamber filled with about 10-15 liters? If yes then upto how much temperature?
Hey dude! Great video! My bedroom reaches 32c and is ridiculously uncomfortable to sleep in. I have a 400mm x 400mm x 300mm polystyrene box with a lid... if i cut out a square hole in the back of the box, mounted this unit so the small fans blow into the box, place 2x 120mm 2000rpm fans in the other side, what kind of results do you think could be achieved temperature wise? I know its a "how long is a piece of string" question.... thanks :)
Can you please tell me what is the maximum life of a peltier
Sir, you seem to know what you are talking about. Got a question for you. I have a 12v koolatron p25 thermoelectric cooler. I was thinking of running a duct from one of the car's ac vents outlet to the lid's air intake so that it will have a colder temp inside. Could this hack damage the unit in any way? Thank you
I wonder if you mated this with a bed mosquito net if that would keep the cool air localised to the bed area ? Need to be sure the heat sink doesnt ignite the mosi net 🔥
You could also make a solar powered cooler box
please i need to know how much heat removed from the cold side in KW
hi mate...im confused to my project...i wanna ask you each item like fan and peltier 12v...then you join the wire all before connect to power supply.i saw your power supply 12v,is it ok??
i think if each item 12v then its totaly 4 item should be 48v...how its work???can you explain?
One fault I can say with these is the freezing up of the cooling side leading to freezing the fan therefore making the cooling ineffective. To improve the item needs bigger cooling heat exchangers and a bigger fan which sits below not touching the frozen cool exchanger
Is there a way to control the cooling strength? Like your FLIR showed 16 deg, could it be set to draw less power but output 23 deg instead? BTW, it was kinda awkward at the end you were moving but had the two "previous" videos show up. I think it is much better if you just froze the last frame instead. :)
Vary the current or voltage.
Simply lower the voltage and the current will follow.
hey bro y dont u try water peltier using cooling coil
How many peltier that i need to make cool 2,5x2,5 m with 3 m ceiling? I live in tropical country summer is the worst. Air conditioner consume a lot of electricity and the price is expensive. I want to make one by myself.
There's probably some math behind working it out but I'm not sure. You'd need a LOT i'd guess. You might want to look into converting a car aircon system instead.
Titoyan Dwihandoko at least 20
Titoyan Dwihandoko ohh its the worst summer then less then 25 would be usel3ss and btw one peltier draws 70 watts 70x25 equals more then 1300watts which is the same as air conditioner lolz
Titoyan Dwihandoko u should use a room cooler quite cheap and efective
hadi hassu i didnt use paltier but i use DIY AC by using copper pipe, pump and ice water
I'm thinking of using your idea to control the temp in my cigar humidor - Thanks
why not put a chunkier heat shield. a cool coffin-like pod seems to be a good idea. I wonder how many of that thing you're gonna need to properly cool a pod.
Solar powered freezer
Water Chiller, Reservoir and Pump for a chilled water quilt, using 1/4 inch poly tube snaked though 2 bed sheets stitched together(like cool suits racecar drivers use).
Hi, Can you dip the heating part into water without the fan attached ? Peltiers are anyways inefficient, so want to know what impact that experiment would have on cold side of the module :-)
Yes you can. I read from a guy that actually dipped it in a large bucket with a lot of icy water and the temperature of the cold side of the peltier got down to -50 degrees Celsius. The maximum achievable temperature difference of both sides of the peltier module is 67 degrees Celsius, so if you manage to cool down the hot side very well the cold side will get very cold.
Can this cooler (pelt ire )continues say 5/6 hours is yes how much load if use car battery without car running
hi buddy, I am very much looking for air-conditioning solution for my 60 bed hostel using a peltier design, the reason for this is fairly simple
1) want to just cool the bed instead of the whole room
2) I could have duct free AC solution (I had considered using an old 1.5 ton AC via 2-4 inch ducts to supply cool AIR to all the beds but that would mean running the AC all the time irrespective of bed occupancy)
3) I am using wall fans right now which use 60 watts of power at 230volts whereas this will be using 12volts at 60-80 watts hence similar power usage *(hopefully)
however I foresee 1-2 major challenge
1) Dissipation of Heat - Generation of heat from the peltier heat side.
Possible solution - I could use a liquid cooling method & circulate the water through an over head tank with 60 units running all night for 12 hrs it should be able to heat sufficient hot water for bath OR atleast warm it
2) I would still be left with the problem of recycling the AIR in the enclosed area. 8hrs of a person sleeping in an enclosed space is unhealthy & dangerous therefore I would still require ducting system for this
question to you - have your observed the time taken to the cool the enclosed bed space that you had experimented & also how much temperature drop was possible
Hi, hope you can do review of power saving devices that can really benefit regular power consumers. I like how you do your test. Very intrigue with them such as plugin capacitors and those that are like stick ons like the surich scalar energy saver. Thanks!
hi how much does it cost andd is it available in the phils? thanks
It's available worldwide since it ships out of China/HK. You can find it on eBay, Ali Express and other similar websites. You can find it be search for: DIY double fan Thermoelectric kit. I think it sells for around 20GBP / 25 USD / 1250 PHP.
hey hi, can you tell me that how to control the temp. with controlling electricity like ac.
Just lower the voltage to decrease the heat pumping effect.
You could also use a thermostat which switches on at one temperature and off at another temperature, but changing the voltage is better for the peltier module.
Reverse Engineer it! Get the Peltier and put them on the roof to generate a generous amount of energy and save it like in powerbanks or use with a 5V or 12V fan. Hhmmm What do you think? There are tons of detailed guides on how to make one online. It could be helpful at least to save a few bucks.
where did you buy that unit?
U can use it for cooling aquarium or as AC for your pet house. or small water cooler
.
How much the price?
hey i like your videos! i recently been tinkering with 2 peltiers i ordered on amazon for cheap. they worked great for a little but but both suddenly stopped working. i cant find any info why i destroyed them as i made a diy mini cooler. they were rated at 12v and had them hooked up to a golf cart battery thats 12v. i had heat sinks on both sides. but im confused on the direction of the cooling fans on both sides....i think i had both fans inward to push air through the heatsink and push the temperatures off of the radiating aluminum. the seller was awesome and sent me free replacement peltiers....but im hesitant to ruin another pair of them when i dont have money to buy more. any suggestions where i went wrong? do you know if a peltier gets destroyed if its internal temp destroys itself by not using heatsinks with fans and thermal paste?
I don't think it makes a huge difference whether your cooling fans are pushing or pulling. Peltiers can fry themselves if they get too hot. I've lost a few due to overheating. I've also had some that just failed for no apparent reason. Not being pushed very hard and suddenly they just stopped working. So I guess to some degree it might just be the nature of the beast when it comes to cheap eBay electronics :P
I appreciate the response! I tried to look deeper into it and took a long time... the conclusion I came up with was to start at the beginning . knowing the seabeck effect and its properties to interconnect 2 different distinctive metallic properties and individual conductivity of the unique properties. Then tried to think of where the system could possibly fail...boiled down to the connectivity of the conjoining of the 2 metals. poor welding or soldering jobs can oxidize with air pockets or cheap materials becoming brittle by the high intensity and expansion/contractions by a direct connection with fluctuation of heat. like concrete getting breaks and crack from extreme weather.
Solar powered cooler / heater + ventilating the unneeded hot/cool air out.
You can use solar panels to power those peltier modules to make an airconditioner that does not cost anything for power which would be especially useful during summer. You can then use the hot side for heating drinks lol
I like your thinking. Really getting the most out of it!
Thanks! I have been wanting to do this but when I went to buy peltier modules, I was discouraged by the price of 450 php a piece
the cardboard box. do that but out of plastic or something with a smooth surface. remove the 2 fans on the coold side. make 2 hole's in the box. get 2 metal tubes. short ones. maybe something like what they use for small vents. now you got a intake and outtake for air. put 1 of the fans you removed in the end of one of the metal tubs. now it will suck air in to the box .cool it down then blow it back out. if you have a smaller diameter at the outtake then the air will compress a bit and get colder. (inntake big outtake small) . on the hot side. remove the fans. take a metal tube cut it in about half on the long side. stick it to the hot sides heatsink. and but a fan on one end. blowing air in to the tube. this should create a "vacum" and pull the hot air with it as it passes the hot heatsink. now you consume less power. sorry about the poor spelling and gramer. am both lazy and dum. :)
Refreshing not hearing CRAP Music and a Voice with some intelligence behind it .. Thank You.
THANK YOU! lets hunt them all down, and kill them dead! their doing utube a disservice! god the suffering i have had to endure trying to get an education.
can you use it to cool gaming console?
+keno Bercasio if you're good at DIY projects and electronics, sure.
Anime fan. Building a Totoro mascot costume that can get up to 140*F inside during the summer. So yeah, I don't dare wear it during the summer. But if you can figure out how to get one of the mini refrigeration units to work in a mascot costume using just a phone battery pack, you'll have some buyers, fast. The one in this video is too large. But I know they make smaller ones that are powerful. Mascot fans work off of a simple battery. But it's not enough. Just circulates the hot air around the mascot costume. You figure that out, make sure the emissions are non toxic, I'm first in line to buy!
They say that alien spacecraft have no exhaust. Maybe they figured out how to recycle heat, haha?
what would happen if the voltage i use is just 5V and amps is only 1 amps
you would be wasting electricity, nothing more.
maybe you can do a aircooler style that blows cool air to your face or body? icebox then the device on the right side and airblows out to you on the left side... so that device is cooling a little area instead.
good airflow for the person...
It should work pretty well. Although I still like the idea of a fully contained area around your body that keeps all the cool air in. But that's starting to sound like a coffin lol
Gadget Addict i think thats good use the one they use to insulate ceiling that looks like a foil with foam so you can roll it up if you want to go out of the coffin hahaha
Space blanket to put under your bed mattress to cool in summer and heat in winter
+Bob Le Clair that sounds perfect. I'm not sure if it has enough oomph for that but I love the idea.
How many BTU/Hour of cooling will it do? I have done a bit of math and a high-end gaming PC will produce 2,500-4,000 BTU/Hour. The 4000 was a bit of an exaggeration. I am sure that peltiers could be used for PC cooling at very low cost if solar powered.
TEC1 Peltiers are usually in the region of 100-200 BTU so you'd need like a dozen of them to even come close to removing the heat of a gaming PC assuming you were effectively removing the heat to an external environment.
How many peltier on it?
2
hmm... low cost AC for japanese capsule hotel-like bedroom... not a bad idea G.A...
or maybe a smaller one for Mr. Black's new condominium unit perhaps.
lol it's funny you should mention that. I was actually thinking of adding it to the cat condo, even if it's just for the sake of a video. It would be a bit pricey to run 24/7 but it might make a fun experiment and an interesting video at least.
Build a dehumidifier... Because its too hot and humid here in PH
Can peltier freeze a food?
A few drops of water but that's about it.
Yes, that being said it would take 7-8 and a well insulated chest
But my cooler with 2 decent sized pads will keep a previously frozen steak frozen
Reverse the polarity and it could be a space heater
YOU CAN MAKE A COOL SUIT WHICH ONE CAN WEAR IN DESERT. REPLY ME IF YOU ARE DOING IT😎
I was imagining the idea of bed AC right before you mentioned it ... lol
any review about drones?😁
so who much price this
