car air-conditioning using peltier

In order to achieve an effective result, you must make the fan draw air from inside the cabin

Peltier high power consumption, low efficiency, not recommended to use unless it's really necessary

Great job. Very clever and skilled. Congrats! Thank you!

This is great. It's possible that you use less coolers and space them apart in different areas inside the cabin to zone the effect over a wider area than ganging them into a single assembly. You've done a great job and it inspires ideas on how to create an efficient setup.

I appreciate the videos when you talk and explain things, thank you very much! I am a big fan of the content you provide, great stuff.

There are 12v Freon compressors that are more efficient, I’ve researched the Peltier for quite some time and it only works well in direct contact heating or cooling but it’s very bad with air cooling for AC’s. Using the condenser inside the car with a fan might be better than that small fan blowing on the cold heat sinks too. So instead to taking the whole thing apart, get another condenser with contact liquid adapters and circulate the cold liquid. It will also have a quieter fan than the smaller fan. The larger the liquid tank the better and you can wrap it in rock wool or use a small bathroom heater tank and turn it into a cool water container that is cooled by the Peltier. Great project, good luck!

Albert beast mode. Awesome work. Thank you.

Hi , the peltier can generate electricity also , my idea is to attach some peltier to the car exhaust muffler so you can support the system

Hello, peltier junction therm couples are very inefficient. There's only a 30-35 degree reduction, that's not a lot. Very high current draw is one down fall to them. I tried making something like what your creating. The net result was not enough cooling. This will kill a battery or over heat a power supply. I'll stick with Freon based A/C's

very clever. nice work mate 😊

yeah if you run peltier modules at 12V you need about same amount of electrical energy than you get cooling but reducing voltage to 6V for peltier module increases coefficient of performance even to 1.8 but then you also need more peltier modules to achieve same cooling power but you use much less electricity

really neat relay circuit. I've done that a few times before, for computer fans edit: can do this with a dpdt switch (one with 6 terminals or wires)

Genius 👏 are you still working on a version 2 please ?

The irony is that the AC unit he cut apart would have been 10000 times more efficient.

LUV U BRO U TOOK IT TOO EXTREME N SHOWN REALLY PELTIER CAN COOL INSIDE A CAR U R DARING MAN SALUTE

Fantastic work, that should definitely cool your EV 👍🏼

Hi Great work on this project. I have done a similar experiment as well. Try the setup in parallel I think one of the specifications mention that a current limiting resistor may be required to ensure that the device does not heat up, this can also reduce the efficiency of your setup. You should use a variable speed pump so you can improve the scavenging effect of heat from the peltier block. Sometimes slowing the speed of flow will be useful to improve with heat removal. You can use PWM control for controlling the speed of your pumps. With your tubing try to have a parallel path , rather than branching into one serial connection which reduces the output flow to your heat exchanger. Need to mount the cooling side of your peltier inside the air duct work

I would like to suggest. You should series all the peltier up to same voltage of your e-car battery to make it efficient and to reduce the current consumption.

Your amazing brother!!! This is so creative and smart.

Have you thought about running it with a pwm to conserve energy? I've always wanted to do this but its good to see you work out the bugs first. It really looks good and well thought out.

that's a great design its a shame Peltier's are super inefficient

maybe the problem is isolation between the heating side and cooling side. all though your workmanship is superb and very neat n clean.

i already did something like this in my subaru forester and its actually super low profile. i made use of my original a/c condenser and as the evaporator i used a small pc water cooling radiator. ofc water blocks on both sides and two little pumps using coolant, and the peltiers im running are 15 amp ones..... 360w of cooling from that works already and wont burn up your alternator. also this system runs by the stock cab controls.

I had often wondered why anyone has not done this before. Great idea

Felicito a este canal por este enorme esfuerzo, yo se bien lo que implica realizar pruebas, armar y desarmar, probar cosas nuevas, trabajé dos años con diversas configuraciones de Peltier tratando de sacar un producto comercial, pero el rendimiento que ofrece es muy bajo, para material didáctico es tremendo, ver que puedo bajar la temperatura a -70 o mas grados es muy satisfactorio con un sistema tan simple, peeeero no tiene potencia para el mundo real, a la misma potencia de consumo de un peltier aprox 60-80w es totalmente funcional un Frigobar a compresor, y un peltier no alcanza a enfriar el mismo volumen del frigobar, pero invito a todos que experimenten por su cuenta, ahí está lo divertido y satisfactorio.

One of the better attempts at making AC with Peltier 👍 The set up would be a lot better if the cooling part was inside the vehicle, recirculating the air, with the peltier hot side coolant being cooled outside of course. Still horribly inefficient though.

The intake should have been from car, with air intake should have a filter. Secondly you have to fit two thermostat ( one for water temperature and another inside the car to save the battery

Why don't you use the other car vents? Also I would swap the fans for some brushless ones that are way more efficient. Other than that keep up the good work.

Making use of what’s available….great video

Great job A lot of work on it

Great ! But how long can the Peltier effect module work without damage?

U make a great job, if u keep your car doors close, and rotate ur car cabin air for cooling then u will get cabine air cool down very quickly and PLS think about air moisture which will convert in water so add a water drain system too

If you had directly added heat sink to the cold peltier side with thermal paste and just made a shroud around it with plexy glass or even pvc for that matter it would have been more efficient i believe..... The more layers of metal you add to the peltier the more it loses its efficacy....... And you forgot to put thermal paste on them too i believe (black metal thingie)✌️

So where did you order all of those wafers you have in this video from?

Present idol 57th 👍 here,,

@Albert Naro I just put a portable house air-conditioner in my car running off of a inverter and it works pretty well... I don't think you're Peltier device is going to be able to make the temperature lower inside the vehicle.... If you can find a old air conditioner like the one you found at the junkyard but it still works and a 3000w inverter I think that would work well for you. It is definitely the next cheapest option

Very good , what's the total cost? You didn't cheap out with anything from copper foil tape, ect ect

make sure to set up a way for it to draw air from within the cabin, this reduces humidity as well. Make sure to set up a way for it to drain properly.

Great job 👍

Award for the world's most inefficient AC goes to Albert Nario. Takes one hour to blow air at 20 degrees, takes another 5 hours to reduce the cabin temperature by 2 degrees and by that time you would have already changed two batteries

Could you explain what the problem is (write it in the description, because I don't speak your language) and why you came to that solution, when there are larger commercial radiators that could solve the same problem in a simpler way with less price and less possibility of failures (unions)

And I thought I was clever making some thing to keep my beer warm, bravo

Cascade Refrigeration might help lower temps even more. Hope it helps? 😊 Very nice otherwise!

Are you recirculating the air or is it pushing ambient air from out side

I think thats a lot of power drawn from the car. excluding the water pump and the fans on the radiator side.

There is a reason those are not in regular use in refrigerators, and more important, in comfort cooling due to the low efficiency. Some modules can have a respectable temperature differential for cooling IR camera sensors for thermal cameras, but high BTU heat transfer applications is not a good fit for the low efficiency of those devices.

V nic...Which material use in water?

That's really interesting but almost any small compressor based design would be more efficient than this. You could have more cooling for less power consumption. Thermoelectric devices are compact and useful in certain applications but they are terribly inefficient.

you need to run the peltiers in switching mode at high frequencies, this will increase the efficiency very much.

Interesting. Cat without an AC? Btw. Why I would drill holes (12:43) when it's all mounted and put the plastic pieces into the circuit to let it stuck somewhere.

I'm doing the same thing for fun. a cold side liquid heat exchange works better. add a bigger hot side radiator with more pumps. more insulation. but yah the portable window ac are more efficient pertaining to power. my interest was to use in a car or solar. basically, the only advantage no inverter required.

At 2:20 those water cooling devices are neat; what are they called?

Yo personalmente modificaría 2 cosas para mejorar la eficiencia 1 sería que tome el aire de la cabina para recircularlo eso podría hacerlo más eficiente, y 2 y este es opcional que si el vehículo está en movimiento ponerle un toma de aire que hagarre el aire entrante del frente para enfriar los peltier reduciendo el consumo

Each Peltier cooler only handles 30 to 50 BTUs at best, you need 5,000 BTUs to come close to a factory A/C.

Sir its good to use inside vehicle rotary air from the vehicle

I think copper heatsink and water blocks makes it more efficient

What is the maximum cubic meters you can cool down with your ac?

Hello sir great video

What about powering ac compressor from car with electric motor?

Bro you have done a great job , kindly use 12703 instead of 12706 as 12703 runs on 3 Amps and cooling efficiency is way more.then 12706

Great job.

you should to change the circuit, the heat sinks put on the hot surfaces, and the coolant liquid run in the condenser, Here is a loss in temperature of the cold air due to its transport. Use water as a cooling medium and place the condenser inside the car cabin

Try to use copper tubing and alluminum water container.

that was same ideas i used in my bus RV because cant run ac windows and drive down road it stick out too far which why i use a lot of peltier and run liquid cooler thur it increases cooling inside it was worth it but it take a lot of homework getting it set up

Maybe try doubling the heat sink to reduce peltier numbers

Becareful NASA will come after you😅😅 great job.

Well done my friend well done.. thank😊 you

what power was removed ?

Make a test by using pwm to control the loads to reach a perfect efficiency

What do you call with that item that water can pass through that base

You should include materials list and link where to get them

Vou fazer o meu inverso. O cooler vai refrigerar a parte quente da pastilha. E vou por o líquido para resfriar o condensador interno da cabine do meu carro. Sugestões?????

I'm going to do mine with the inverted system of the one presented. I'm going to put the liquid to cool the internal condenser of my car. And cooler to cool the Peltier insert. with ventilation.....?

Loop the sirculation air from inside car, make the air more cool

Aküyle bağlamış olsa kaç dakika dayanacak, motor piyasada yok, elektrikli araç mı acaba diyeceğim benzemiyor.

Like From Brazil 🇧🇷

peltier is actually a heat pump!!! it generates 80 percent heat to generate 20 percent cooling. So. its COP {coefficient of performance} is not like a n airconditioner which i guess is 10 to 20 times more efficient. I would remove your build and attach it to a little mini fridge case and use it as a chiller / fridge in a camper RV and utiilise a pwm controller which can be tailored to drop your watts consumption by 5-10 times.

peltier efficiency is low maybe 20%, heat pump (AC) has 150% when cools and 200% when heats,

*Beautiful*

Very good 👍👍👍😊

I wouldn't bother. It's a nice novelty but it is highly inefficient heat pump. It consumes vastly more energy than it removes.

Just enough cooling power for Barbys toy mobile 😅

Make another experiment using small DC compressor

Use also evaporator inside the car for best result

Amazing job....Peace

Very nice 😮

I have a similar idea but i want the Hot side of the peltier to be a pc water cooler (4fans) and the cold side pc water cooler 2 fans no cooling the peltier with Air but water and the cold side with water too so you can put a cold radiator on the inside and if its winter y could change the peltier to do the same but in reverse cold out hot in

Circulate air from inside. It will make a huge difference

Very nice ❤

The cooling efficiency of a long heatsink is very low. Last heatsinks in air flow cooled by hot air from the first ones. Radiator must be short and wide, same as car radiator. I think, if you cut half of modules, efficiency will not dropped down more then 10..20%.

You need to fix blower somewhere inside the car so it will suck the internal air in this case ur ac will work more efficiently

Idol ko talaga to :) sir albert looking forward to meet you in person, sa tropa ko yan chinese electric car sa pampanga :)

if you use TEC1-12703 peltier it would be better. its very power efficent .

Is that the new technology?

Try using the heat from the exhaust with a set of peltiers to produce power, than use the power for the cooling peltiers. That way you wont kill your battery or alternator.

Did i read that right 22 amps?

anung pump ginamit mo idol?

Instead of using water as a heat conductor I think aluminum heatsinks are a better heat conductor.

Cool project, pun intended.

Now encase every cold part under that hood with pool noodles and or expanding foam
