make a car AC using universal blower-evaporator unit, it's already have everything from blower, case, expansion valve and thermostat. It only needs piping, compressor and condensor. But, instead of going with car air-conditioning compressor, go with a 1/2 hp mini split compressor and use psw inverter to run it. that way i think you'll get better performance
This was just a fun project afterall. Of course, peltier modules are not that efficient in exchanging the heat. Although the compressor may need a maintenance like the refrigerant, oil or the filter check after some time.
so ,this being your second version ,did it work better than the first ,the first seemed to have destroyed your engine bay by the looks of it,this one didnt work that well either did it ,for the effort,peltiers just dont ever work the way you want them to ,cheers guys
ye but 1300W in a ac compressor has atleast 3000W (probably more) of thermal moving power, peltier modules literally will only move about as much as they pull
Peltier is just for electronical chip cooling for very limited spaces. Peltier doesn't make any heat gain. If you use compressor and refigirant gases you get as high as X 4 cop values. 600 w is very high power for batteries. This is only conceptual system we electronical engineers use peltiers to cool our chips more than 40 years
You may want to use a gas compressor that only works when the car is moving? it surely will be more energy efficient. I loved that little electric car. LOL.
if you put a peltier device on the hot side with some thermal compound between them it will convert the heat to power and you should get about half the power back into the system just need a one way circuit back into the input... and the other side can be used to pre chill the warmed water coming back in...
TEC1-12706 (12v 6A) 24x 12v 6A (72w) TECs Thats 1'728w on layout 3s 4p So that is then 36v 24A (864w) per XT60 So need 36v 48A or 72v 24A power supply But your running it on 12v and have relays to switch 2s from/to 2p mode ? Basically running it at 1/3 power or 1/6 power ? If I understood it correctly 🤔 So sacrifice power to efficiency If I remember correctly at full power those modules are like 5% efficient at full power But what is the efficiency at 1/3 or 1/6 power?
ps the hotter it is outside the more cooling youll get as it trys to normalize the inside and outside ,also once the car is moving that will help,also im unsure if those water blocks have the correct type of fins inside for heat transfer like cpu water blocks made of copper
ok,yes i worded that wrong i ment exhaust that vents the hot side out,the hotter it can exhaust the colder it will get,,i wasnt paying attention was wondering what happened to his car
@@angusmcgil This system is terribly inefficient for using as an air cooler. This guy has like 24 of those peltier modules which draw a lot of power, while providing minimal cooling. While it works for the sake of a CZcams video, it's impractical.
Good work but keep in mind, TEP are very inefficient when it comes to power to work ratio.Nothing beats a good old compressor cooling system. I would hunt for a 200 watt compressor and make an ac from it, it should beat this peltier experiment.
It makes no sense to use Peltier modules in a car air-conditioner because their efficiency is very low compared to a compressor and in a car electrical power is generated with an alternator and further loss of efficiency in the conversion from mechanical to electrical power.
Good idea but use too much energy and car's battery very soon get broken.... This is good for home air-conditioning because there you don't have limit for energy
For a car, the motor should be always running since the alternator is supposed to power the A/C and not the battery actually, unless you have an external source.
its a bit expensive but how about replacing your aluminum water blocks with copper. it should increase thermal conductivity. also why not use distilled water instead of coolant?. i mean you risk boiling or freezing water. but thats why you have heat sinks and giant fans.
I wonder why this is done though. The 3 in series will get 4volts each and will cool less. Instead each Peltier getting 12volts would have worked better.
I think you are getting as much out of it as you can for an AC unit. Maybe if you added an orifice and used alcohol for the coolant side you could drop the temp a bit but then your getting into adding some pressure into the system. It probably would be worth adding the extra pump for sure.
Peltier is a very inefficient for the purpose, it has high current draws and for the car it will tax tax the alternator heavily let alone the electric battery powered car, you will be better off with butane gas air coolers instead

Easy your IT help in the future may suffer now. That comment will get ya credit card hacked 😂😂😂😂
@@ianbuilder make another video about AC refrigeration system, but use a universal car indoor unit :D
Great, love your attention to detail. I had thought about something similar, but in reverse, to tap extra energy.

I like your craftmanship. That's improved very well
Compressor AC 10times more efficiency than peltier
yes that's true..
no freon .. 🤤 but can subtitute it with propane or LPG
Great ! But how long can the Peltier effect module work without damage?
Great design and good craftsmanship. Professional video recording. Nice product. Keep making more videos like this one.
Thank you very much!
Ang galing nyo naman sir. Sana magawan nyo ako ng ganyan din para malagay ko sa sasakyan kong e-car. Salamat.
Brilliant! Thank you for sharing this informative video. Greetings from Madang, Papua New Guinea!

Nice.Thanks for sharing. Are you happy with it?
Ese es uno de los coches chinos que envian para armar como muebles de IKEA?
Very good! A RV / motorhome 12 volt electric AC pulls at least 1300 watts, electric motor running a compressor pump.
ye but 1300W in a ac compressor has atleast 3000W (probably more) of thermal moving power, peltier modules literally will only move about as much as they pull
exactly what the dude above says. 1300w on a compressor may move 4000w or more. my AC is 3500w (12000 BTU), 1000w consumption
Salamat sa pagbahagi sir.ok rin yan dahil mahal ang gasulina dadag cunsomo sa gas pag compressor belt driven ang gagamitin
Very good!

How about use bigger radiator
Faster transfer heat
Higher efficiency
nice job !
how much in total? cause its about $65 a set and im not going to watch but would like to hear back from you when i watch it later.
Nice idea

Sir, very well done. Excellent. But why connect 3 Peltiers in series ? Won’t the voltage get divided and the Peltier cool less?
optimum current draw.. 2 in series more cool more watts but for efficientcy try your self..
cool build, however efficency of a peltier-system is around 5% so you need humongous power to get any useful coolingpowerout of it..
Good job bro
560w/12v=46.66A? Can the alternator handle it?
I DO like the design, very creative. Good Job👍🏻
What is the manufacturer name of that car? I am really interested in it sir.
impressive!
dude where did you buy all this staff?
a very god job! what for a nice car is it? thx
Its a good idea but peltier consume to much power more than compressor
Un hombre virtuoso 🎉🎉🎉
What is the total amperage?
You have my attention.
TEC1-12706 (12v 6A)
24x 12v 6A (72w) TECs
Thats 1'728w
on layout 3s 4p
So that is then 36v 24A (864w) per XT60
So need 36v 48A or 72v 24A power supply
But your running it on 12v and have relays to switch 2s from/to 2p mode ?
Basically running it at 1/3 power or 1/6 power ?
If I understood it correctly 🤔
So sacrifice power to efficiency
If I remember correctly at full power those modules are like 5% efficient at full power
But what is the efficiency at 1/3 or 1/6 power?
Tengo la misma duda... Como llega a los 24V?
ps the hotter it is outside the more cooling youll get as it trys to normalize the inside and outside ,also once the car is moving that will help,also im unsure if those water blocks have the correct type of fins inside for heat transfer like cpu water blocks made of copper
Wrong! more heat outside means less cooling.
ok,yes i worded that wrong i ment exhaust that vents the hot side out,the hotter it can exhaust the colder it will get,,i wasnt paying attention was wondering what happened to his car
wonder if stacking them might help in that project ,stacking seriously increased peltier fridge conversion we did few years back

yeah we know that,but hes having a go ,hes being creative in his reality and efficentcy isnt allways that important@@sumanbasnet8587
The outlet temperature of an AC cooler is about 4 °C. There is still a huge difference.
Very good
Total current draw?

I agree with you 👍
Downside of using peltier is the amps or power that it draws and not crucial on hot weather lol
Excelente 👏👏👏👏
What is that car man? Chinese model/make?
That's awesome man, great work, fun idea
Nice try keep it up bro. God blessed you.
Thank you, I will
nice !
Can you make it for my car or install in it?
How much cost?
Let me know about it
Why you make the peltier in series? Is it to reduce the amps?
yes.. and lower the voltage per plate more efficient..
Put that 600w to a compressor and do the maths
Exelente
FROM WHAT COUNTRY ARE

Galing sir ah,pwde ho bang pagawa,tnx

Siiiiiiiiiiiiiiiick!!!!😊❤
Just hook an ac compressor to the engine and do it right then you will blow about 5⁰c like it should be....
Genious
Me podría decir que es un relay y spin
One Bump the whole thing pops out on the road.😮
Where do i get the small radiators?
computer radiator
You live in a very hot place ;)
According the acrylic panel he had = the Philippines, lower Orient ~ that country is tropical
Good idea but use too much energy and car's battery very soon get broken....
This is good for home air-conditioning because there you don't have limit for energy
Yes, you are right, it's good for camping when you have extra battery and you need ac
For a car, the motor should be always running since the alternator is supposed to power the A/C and not the battery actually, unless you have an external source.
its a bit expensive but how about replacing your aluminum water blocks with copper. it should increase thermal conductivity. also why not use distilled water instead of coolant?. i mean you risk boiling or freezing water. but thats why you have heat sinks and giant fans.
Copper can react with water.aluminum is better
AC, with NO moving parts, short of the fan.
Cool.
POV: good bye battery energy
vs inverter and refigerator or home freezer.. just open the door add fan .. for simpler
That's has to be more than 20 amps from all those Peltier
Good❤❤
I feel what he has in all that he could have just got a new ac installed in the car lol
24 cells peltier 12706 = 144 ampere. 13.5 volt x 144 = 1944 watt. The engine lose 3 HP power if the alternator survivor at 144 Ampere
But this is 24V and connected in series.
如果功耗达到600W的话，这个制冷效果有点差。用热泵更加好
great....🥶
boss pwede ba magpagawa sayo? pang camping sana na aircon. sure buyer po
Add links to parts and/or a PDF of parts so we can build it too
where the car engine is placed
its a small electric car
Efficient ba sya sir??
я думал потом будет общий план как во всём районе электричество потухает
Why you chose 21706 peltier ?
it fits on the computer cooling block...
@@albertnario4877 I think 21703 best choose for best colling
use 12703 it gets coldest
4 groups 1 group is connected in series
4 groups connected in parallel I guess
I wonder why this is done though. The 3 in series will get 4volts each and will cool less. Instead each Peltier getting 12volts would have worked better.

Good Good
it can be powered by heat from the engine using peltier .. no wasted heat 🤤
for non ev
Peltier cannot be powered by heat, only by electricity.
No vale la pena esos 20 grados en pleno verano a 35 grados de calor. Sería nada. Con el consumo no vale la inversión. Y tiempo.
Isn't chipper buying a new factory one?
buying the whole thing is getting you stock on that design and learning in process is the best thing.. 👍
20°c is.still hot during daytime.in south east asia. if below 5°c it cold
don't equalize those number with AC remote, AC remote didn't actually measure the real temperature around you
@@worldshell2313 i already try with thermometer 20°c still hot in my country because of the humidity
Power losses ?
need big alternator 50A always at max.. not durable enough.. at least 80A or 100A
Diy home based do it kindly.
2 to 5% effiency
24 peltier units + battery + bldc controller will cost more then car air-conditioner unit😅
NIce? With this powerdraw, u can buy a proper ac and all is fine...
Peltier is a very inefficient for the purpose, it has high current draws and for the car it will tax tax the alternator heavily let alone the electric battery powered car, you will be better off with butane gas air coolers instead
Hola . . . saludos Que estupendo trabajo te feliciito , pero me quedo con una ingconita se te fueron unos cuantos Dollares . . . 😎👽
After 15mins the battery is dead 😂
Its a very good idea, but it's still very inefficient unfortunately
yes it's not that efficient for an AC..
Conductional heat transfer rate of your design is huge mess decreasing efficiency by greater margin
