@@pjoskar1I project to build it in Peugeot 206 without AC. I will place 2 modules 12703 in the intake grid on bonnet with hot radiator cooled by speed air of the car and cool air will aspirate in AC cockpit in hepa filter... I conscient that system is no optimal... But effective cost is better that setup AC with compressor and change all system cooling car.
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!
@@Darkipodyou may want to start with a search for 12 volt refrigerator compressors. Refrigeration compressors, etc. I would suggest not using Freon. But instead propane. Propane is a cheap readily available item. And it works excellently as a refrigerant. It is also the most environmentally safe refrigerant.
@@dannydoolhoff7657is explosive asf too, I've seen houses completely destroyed because an AC charged with propane, don't tell people to do such dangerous things
@@hansmuro7355 there are many units on the market today that use propane as the refrigerant. Many water coolers, ice makers, refrigerators, and freezers now use propane. As a refrigerant it is referred to as R290. "The R290 system has the advantages of a fast cooling rate and high refrigeration efficiency. The average specific refrigerating effect of the R290 system is approximately 52% higher than that of R134a with the optimal charge amount." Propane is excellent as a refrigerant, and works at lower pressures than the old R-12. An R-12 system can easily be cleaned and converted to propane and because of the lower pressures, also extend the life of the system. Yes, precautions are needed as with all refrigerant systems.
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.
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
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
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
@Demostenes Ramos instead of the thermostat turning them all off and all on, maybe switching them to 12v (maximum cooling) down to 6v (less cooling) when the set temperature is reached. This will help to reduce load on the batteries and peltiers, increasing its life span and increase efficiency.
@@ka-i I saw an amp draw of 65 amps. That's a crazy load to have on a car battery or am I mistaken ? I would assume it would be more efficient having a vapor compression cycle as it would reduce the load down by alot.
@@derrickenbuenosaires absolutely a vapour compression system would be much more efficient. But it needs the skill of making it and also finding the parts to make it. The vapour compression system has a higher initial cost, but is much more efficient than a peltier system. Depending on how they system is designed, they can have a Coefficient of Performance of up to 7, but realistically around 3-6, which still greatly outperforms the current peltier system
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.
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)✌️
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.
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.
Great tinkering , I am tinkering with using the cold to condense water from the air through a copper pipe coiled. I will put a water exchanger on both sides of the peltier and may store the heat in a sand storage to use later to heat a house. You could pass water into the car and put it through a cpu radiator with a p.c fan on it .
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
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.
Peltier devices need constant current because when off they begin conducting the hot side back into the cold side making them significantly less efficient. www.ti.com/lit/an/slua979a/slua979a.pdf
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.
could just put a fan and pipes into a portable/12v fridge to get the same effect and only 50watt when running would even fit in the front of that car for duel use .
@@maxgood42 No. Those extra-mini refrigerators are also thermoelectric and have even less cooling power than this does. Those only have one thermoelectric device, compared to the four pictured here. Better to not bother, and just open a window.

I am no expert in peltier cooling, but i thought the 12703 module is the most effiecint between all other peltier modules needing only around 3 amps and its also the coolest clocking around negative 15 to 20 c. While others only hoovers around +1 to +5 c. With that being said, theoreticly the 12703 module should cut your amp consumption in half while offering almost double the cooling.
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.
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
@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
Hi, and please tell me how much power do you have an air conditioner? How many watts? And the battery in the car is 12 volts and the generator is how many amps? I was also interested in this option
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
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
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.
Using Peltier modules is not a wise thing because you cant get same output over a time. Inside Peltier it gets corroded due to like mist inside within the each Peltier modules. few days you will notice the in efficiency of using those. But I appreciate your idea and your skills of doing such a innovative thing.
Its bullshit, although what this person built isn't that efficient your comment is manure, a good paltier unit is sealed and has long life provided good ventilation it doesn't "corrode" like that
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)
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.
@@albertnario4877 great ... peltiers can only attain a max of 20 degrees drop from ambient temperature. A car interior is much higher than ambient as dashboard, etc act as heat storage, maybe around 10-20 degrees higher than ambient. An airconditioner is perhaps 50-100 times more efficient vs peltier under these circumstances. This exercise is fruitless!!! Watch others videos who tried such!!
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
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.
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.
Nice work Albert, congratulations, but improve this by removing water coolant, you will save on 2 motors, instead use big heat sink on hot side. put Peltier in a case such a way, that the cooler side will be inside the car cabin, and on hot side that 1 big fan will eliminate the heat efficiently. Rather you don't need that fan too, since you are using it in front side of the EV, just try it with atmospheric air flow without fan. Trust me you won't regret, even it can be powered by solar. Hope you like my idea, on which I am working since long. Thank you.
i disagree , since he is using It in a car , when the bonnet is closed , it could double the heat inside the closed space. for him to use a fan he will have to make a huge hole in the cars body for the fan(no one would do that) that is also considering he will have to make another hole for hot air exhaust . secondly peltier module's cooling depends on how well the heat is disapated from the hot side , water blocks make it extremly efficient for faster and reliable cooling regardless on outside temperature and is also very quite. he has definitely made the most efficient peltier cooling system by far on youtube.
I agree on the water but I would recommend using something other than the anti freeze for the coolant, pure distilled water has better cooling capacity and is a lot thinner which will draw more heat away and put less strain on the pump due to the viscosity. Also on the cooling side he should put the heat sink with thermal paste directly on the peltier, it's losing a lot of efficiency having to conduct the cold through multiple surfaces and no thermal paste on the cooling side has small channels of air that is a poor conductor as well. For the fans and pump he should use brushless to save a lot of energy and the cooling air intake should be taken from inside the car so it's recirculating making it even more efficient. In not bashing his work at all, I love it, he's done a great job but I just want to help him with suggestions like he asked. I'm not positive but also if he were to use a large capacitor for the power to the peltier I would think he could have that charged as well as the battery at the same time giving him more efficiency and drawing less power with less power spikes, especially stuttering startup when it uses the most power. This is so awesome, a solar panel added to the roof to charge the cooler battery and large farad capacitor alike save him even more, he'd get a charge while parked in the sun, it would help the battery last longer on drives in the sun as well. I'm also thinking to plumb the radiator outside the car are where the air from moving the vehicle forward would cool it and have the fan on a switch or thermistor to switch on when he's not moving, parked, at a light, or drive-thru would meet him more efficiency too! I love this idea that he's come up with, best use of peltier units I've seen.
@@nikhil126 nah, I have seen better systems. One guy made a beer can chiller. He has vast experience. I liased with him after wasting 3 months on peltier. He admitted despite his success, peltier was a " no go" in terms of refrigeration!!
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.
I'm not a eletrictian but he also said at they where running 6 volts in a series setup (in the video its a mix of series and parallel,half what is needed to run one TEC1-12706, all these "magic" numbers to get "magic" results. Not to mention the battery they used to mislead everyone to think it was being used for the peltiers or the thermomters with those tiny wires would have melted. Another RUclips channel giving false information to get views.
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.
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%.
better you put peltier inside cabin, i think little efficient rather than outside, because the air were was cooled circulated and sucked by blower then temperature down. and also your waterblock not blown by hot air were coming from radiator instead of condenser. we wait the update.
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
There are 16 peltiers fitted in this project. The current required will be 16*6=96 amp for the peltiers alone. May be total current required shall be 120 Amp. Which alternator of a normal car can generate this much current with out damaging itself and the battery. Seems illogical and hypothetical project.
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.....?
Смысла нет городить такую конструкцию т.к. на модулях Пельтье кондиционер будет потреблять ток больше чем обычный кондиционер на фрионе. Модуль Пельтье имеет очень низкий КПД и что-то собирать на нем нет смысла!
There is no way to make it efficient in a practical manner. The peltier modules are just very inefficient by nature. It is only good for small projects or when you just want to cool a small area without any regard for power consumption. A small window air conditioner consumes less than 500 watts while your setup consumes about 1000 watts. That is just the nature of these things.
peltier is the electronic device with the worst efficiency, 700W for cooling with such a small result I think it is a huge waste of energy excellent use of peltier I think only in portable dehumidifier device for 5x4m room, with average electrical power usage at 50W
"Clean".... 1/10th the performance for half the energy. Real clean. You realize that coolant for air conditioners nowadays doesn't damage the ozone layer anymore right?
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

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.
you have to recycle the cold cabin air and lower the volte's so it can be more efficient you have them running at max power.
Using Peltier modules is not a wise thing because you cant get same output over a time. Inside Peltier it gets corroded due to like mist inside within the each Peltier modules. few days you will notice the in efficiency of using those. But I appreciate your idea and your skills of doing such a innovative thing.
Its bullshit, although what this person built isn't that efficient your comment is manure, a good paltier unit is sealed and has long life provided good ventilation it doesn't "corrode" like that
I wouldn't bother. It's a nice novelty but it is highly inefficient heat pump. It consumes vastly more energy than it removes.
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
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)
Great ! But how long can the Peltier effect module work without damage?
Very good , what's the total cost? You didn't cheap out with anything from copper foil tape, ect ect
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.
version 2 is on its way, it consumes 30% less energy but 2x more colder
@@albertnario4877 great ... peltiers can only attain a max of 20 degrees drop from ambient temperature. A car interior is much higher than ambient as dashboard, etc act as heat storage, maybe around 10-20 degrees higher than ambient. An airconditioner is perhaps 50-100 times more efficient vs peltier under these circumstances. This exercise is fruitless!!! Watch others videos who tried such!!
Hey, this would also make a great heater in winter with those percentage
@@albertnario4877 still waiting for version 2.
Making use of what’s available….great video
I think copper heatsink and water blocks makes it more efficient
maybe the problem is isolation between the heating side and cooling side. all though your workmanship is superb and very neat n clean.
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
So where did you order all of those wafers you have in this video from?
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.
Peltier produces a marginal amount if electricity.
Are you recirculating the air or is it pushing ambient air from out side
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.
Your amazing brother!!! This is so creative and smart.
Nice work Albert, congratulations, but improve this by removing water coolant, you will save on 2 motors, instead use big heat sink on hot side. put Peltier in a case such a way, that the cooler side will be inside the car cabin, and on hot side that 1 big fan will eliminate the heat efficiently. Rather you don't need that fan too, since you are using it in front side of the EV, just try it with atmospheric air flow without fan. Trust me you won't regret, even it can be powered by solar. Hope you like my idea, on which I am working since long. Thank you.
i disagree , since he is using It in a car , when the bonnet is closed , it could double the heat inside the closed space. for him to use a fan he will have to make a huge hole in the cars body for the fan(no one would do that) that is also considering he will have to make another hole for hot air exhaust . secondly peltier module's cooling depends on how well the heat is disapated from the hot side , water blocks make it extremly efficient for faster and reliable cooling regardless on outside temperature and is also very quite. he has definitely made the most efficient peltier cooling system by far on youtube.
I agree on the water but I would recommend using something other than the anti freeze for the coolant, pure distilled water has better cooling capacity and is a lot thinner which will draw more heat away and put less strain on the pump due to the viscosity. Also on the cooling side he should put the heat sink with thermal paste directly on the peltier, it's losing a lot of efficiency having to conduct the cold through multiple surfaces and no thermal paste on the cooling side has small channels of air that is a poor conductor as well. For the fans and pump he should use brushless to save a lot of energy and the cooling air intake should be taken from inside the car so it's recirculating making it even more efficient. In not bashing his work at all, I love it, he's done a great job but I just want to help him with suggestions like he asked. I'm not positive but also if he were to use a large capacitor for the power to the peltier I would think he could have that charged as well as the battery at the same time giving him more efficiency and drawing less power with less power spikes, especially stuttering startup when it uses the most power. This is so awesome, a solar panel added to the roof to charge the cooler battery and large farad capacitor alike save him even more, he'd get a charge while parked in the sun, it would help the battery last longer on drives in the sun as well. I'm also thinking to plumb the radiator outside the car are where the air from moving the vehicle forward would cool it and have the fan on a switch or thermistor to switch on when he's not moving, parked, at a light, or drive-thru would meet him more efficiency too! I love this idea that he's come up with, best use of peltier units I've seen.
@@nikhil126 nah, I have seen better systems. One guy made a beer can chiller. He has vast experience. I liased with him after wasting 3 months on peltier. He admitted despite his success, peltier was a " no go" in terms of refrigeration!!
i will consider all your comments, thanks.. 2nd version is coming
@@anthonyortega3136 best use of peltier!! Thts totally incorrect!! It's a heat pump being used to cool!! Crazy!!
Present idol 57th 👍 here,,
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
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.
2x8 = 16 peltier x6A =96A blum kipas dan pompa. Kalau untuk mobil mana cocok gan aki innova aja paling 70 A
I'm not a eletrictian but he also said at they where running 6 volts in a series setup (in the video its a mix of series and parallel,half what is needed to run one TEC1-12706, all these "magic" numbers to get "magic" results. Not to mention the battery they used to mislead everyone to think it was being used for the peltiers or the thermomters with those tiny wires would have melted. Another RUclips channel giving false information to get views.
Can you use solar panels for that system?
Absolutely! 😊
I think thats a lot of power drawn from the car. excluding the water pump and the fans on the radiator side.
Cascade Refrigeration might help lower temps even more. Hope it helps? 😊 Very nice otherwise!
You should include materials list and link where to get them
Where it is available and cost
Instead of using water as a heat conductor I think aluminum heatsinks are a better heat conductor.
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.
Peltier are not very efficient for the amount of wattage they consume and they can only cool down to 20 degrees below ambient temperature.
Sir its good to use inside vehicle rotary air from the vehicle
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%.
peltier efficiency is low maybe 20%, heat pump (AC) has 150% when cools and 200% when heats,
Use also evaporator inside the car for best result
WOW!!!!ano kaya temperature comparisson sa sasakyan? tas worth it ba mag peltier? sa pagkaka alam ko kasi mas maliit yung effeciency nya.
Not suitable for cars.
It will drain your batteries in 3-5 hours and the cooling effect is slow. A small compressor is much better.
Aküyle bağlamış olsa kaç dakika dayanacak, motor piyasada yok, elektrikli araç mı acaba diyeceğim benzemiyor.
V nic...Which material use in water?
better you put peltier inside cabin, i think little efficient rather than outside, because the air were was cooled circulated and sucked by blower then temperature down. and also your waterblock not blown by hot air were coming from radiator instead of condenser. we wait the update.
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
There are 16 peltiers fitted in this project. The current required will be 16*6=96 amp for the peltiers alone. May be total current required shall be 120 Amp. Which alternator of a normal car can generate this much current with out damaging itself and the battery. Seems illogical and hypothetical project.
Next he will construct a high performance engine for the vehicle using ordinary kitchen utensils and a box fan so stay tuned !
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.....?
Смысла нет городить такую конструкцию т.к. на модулях Пельтье кондиционер будет потреблять ток больше чем обычный кондиционер на фрионе. Модуль Пельтье имеет очень низкий КПД и что-то собирать на нем нет смысла!
There is no way to make it efficient in a practical manner. The peltier modules are just very inefficient by nature. It is only good for small projects or when you just want to cool a small area without any regard for power consumption. A small window air conditioner consumes less than 500 watts while your setup consumes about 1000 watts. That is just the nature of these things.
What about powering ac compressor from car with electric motor?
peltier is the electronic device with the worst efficiency, 700W for cooling with such a small result I think it is a huge waste of energy
excellent use of peltier I think only in portable dehumidifier device for 5x4m room, with average electrical power usage at 50W
"Clean".... 1/10th the performance for half the energy. Real clean. You realize that coolant for air conditioners nowadays doesn't damage the ozone layer anymore right?
Great job
A lot of work on it
What is the maximum cubic meters you can cool down with your ac?
While this peltier uses 70-90 watts each but this setup Looks like each peltier is using 12watts of power .
Loop the sirculation air from inside car, make the air more cool
Not recommended due to high ampere input ...not efficient as compared to compressor ones
if you use TEC1-12703 peltier it would be better. its very power efficent .
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
U r right sir
Circulate air from inside. It will make a huge difference
wow only 22 amps for some cooling, seems enviroment friendly
Make a test by using pwm to control the loads to reach a perfect efficiency
At 2:20 those water cooling devices are neat; what are they called?
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
How much amp did you draw and how noticeable was the difference ? Thanks :)
@@TheThunderwars 10 peltier with two water pump and 2 fan about 17amp with deep cells battery last about 20 hours if you add 3 deep cells battery last about 85 hours
Like From Brazil 🇧🇷
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?????
Why they manufacture a bigger peltier .y? Y?
What do you call with that item that water can pass through that base
Did i read that right 22 amps?
Bro. You better buy a 0.4hp window type aircon and 12/24volts to 220volts power inverter. Its consume 400watts only. And more efficient than peltier
