How To Make A Portable Freezing Air Conditioner From Peltier For Both Room And Car | DIY Air Conditioner For Summer At Home.
In this video, I will show you how to use Peltier to make a portable air conditioner. This idea comes from my real needs. My car has three rows of seats, but there are no air conditioning vents in the back two rows, so it is hotter than the first row, especially the third row. So I plan to DIY a portable air conditioner. It can be used for both my car and my bedroom.
To make the air conditioner more retro, I used wooden boards to make the case. Peltier is used for refrigeration, and the water tank is used for heat dissipation. At the same time, I use a temperature control switch to automatically control the start and stop of the refrigeration unit, achieving a constant temperature effect. Moreover, the wind speed can also be adjusted. For better aesthetics, I also added some LED lights.

Smart idea using the water to cool down the peltier!
Thank you for your comment😀
That tiny table saw is the cutest thing I've ever seen.
😊I like that saw very much
Finally someone who did what I was thinking, THANKYOU for making this video with this awesome Air Conditioner 👌👍.
Thank you for watching and commenting😀Use a larger water tank and put it in a foam tank for better results👍
I'm so annoyed at how much work you put into the build and then had the most god awful screws that didn't go in straight or look right. =(
Thank you for your comment. I will improve next time😀
Yeah that’s almost 9999999 BTUs , it will work especially if there is high humidity 😂😂
Thank you for watching and commenting. By the way, I wouldn't say I like high humidity😂. Have a good day!😀
I bet this will take a lots of current and and enough cool 😌
The total power is approximately 200W😀
SO UNDERRATED EVEN THOUGH I WOULD PROB NKT MWKE THESE IT FUN TO WATCH! WISH U GOOD LUCK🎉
Thank you😀
nice video!👍
😀
This is a great idea, thank you for sharing this idea with the world, just curious, what size water pump did you use? I think a smaller water pump that uses very little watts would suffice, I've seen aquarium water pumps that say "160 GPH at 10 watts"
The water pump is very small, 5V, 3W, 200L/H. Thank you for your comment and for the like. Have a good day😀
Thanks for sharing.
I have some questions hoping you could advice,
1. how do you design/decide on how big is the reservoir to cater to 3 peltier?
2. The reservoir in your video, how long can it last before you need to change the water?
3. Normally at what temperature you change the water?
Just an idea maybe some improvement could be done is to have a probe installed in the reservoir to monitor on the temp?
This is a very good idea though on improving AC in campervan without needing to open an vent hole.
Great work!😀
Thank you for your comments and suggestions.😀
The temperature difference between the hot and cold ends of the Peltier can reach 60-70 degrees Celsius. Cooling the hot end can lower the temperature of the cold end. The minimum temperature at the cold end can reach -50 degrees Celsius or even lower. So the lower the water temperature and the larger the capacity of the water tank, the more conducive it is to heat dissipation at the hot end, thereby reducing the temperature at the cold end.
My water tank is 1.1L. Due to the small size of the water tank, the water temperature rises rapidly and can reach over 70 degrees Celsius in one hour. At this point, I need to change the water. I have installed a temperature probe (video 6'24"~06'29") on the metal water tank connected to the hot end of the Peltier to detect the water temperature. But your suggestion of setting a temperature probe in the water tank is better.
My car's third row seats don't have air conditioning, so I made this portable air conditioner. It partially compensates for the shortcomings of car air conditioning. But I think there is still a lot of room for improvement, including the following aspects:
Replace the water tank with a larger capacity.
Heat insulate the water tank in a foam box and add ice cubes inside.
Thank you again for your feedback and sincere suggestions.😀

Probably gonna work for like 15 minutes. I also tought about dumping heat into water... I have to try something else
Try to dump the heat into daily use hot water... You know. Use cool side for cooling in the house, and the hot side dumped into water usage. Dayum thats also cheap and the energy is not wasted.
@@BillMingLabs If the car is moving you use the air to water cooler from outside the car to cool the water and/or the Peltier and/or anything that gets hot.
WOW, Amazing job...Peace
Thanks for your compliment. Have a good day 😀
nice job
Thank you for your comment. Have a good day!😀
whats the blue liquid tho?
It's water. I added blue paint to the water.It is used for heat dissipation.
Probably just coolant
It is water. He is using the peliter elelments to cool down the air and exhausting it into his car at the expense of heating up the water reservoir in the blue container. I want to do the same but battery powered. Thanks a lot for the great video.
@@JCT-@JCT- You could use more and higher power peltiers if battery powered. by the way, bigger water containner😊
Does it really chill the car? im looking for doing something like that for cooling my car since it dosnt have Ac, does it really cool down ?
My car has no air conditioning vents or fans in the third row. I put it in the third row. I think it's better than a fan. Of course, many areas can be improved, such as replacing a larger water tank and putting it in the foam tank, increasing the number of Peltier, etc. Thank you for your comment😀
List of materials pls😢
Finally you got new subscriber 🎉
Dear can you sale it? I want to purchase it? I like it
Thank you for subscribing😀I intend to continue refining it. After enhancement, it should fetch a good price😁
bravoo
Thanks😀
Very nicely built. How much power is consumed while running?
Thanks:) About 200W per hour, including peltiers, fans, water pumps, LEDs
@@BillMingLabsbut it doesn't work that efficient
@@BillMingLabsafter some time it's start to gain in temperature at cold side....and other thing is when we use fan on the cold side the peltier cooling rate doesn't compete with the flow rates of the fans........because at normal or high speed when new air enters and gets cold the peltier slowly loses its temperature and from there the temperature rise starts......because peltier cooling speed doesn't matches the fan throw speed......if I close the fan then stored air inside the container starts to cool down again.....
@@BillMingLabshow this problem can be correct? I have used two peltiers and two water blocks for each and connected with the pump also.....and used the heat sinks on the colder parts in order to get expansion on cooling so the air flow through the fins and gets cold before reaching the fan.....and used a single small fan for it.......because if I use two or a big fan then above mentioned issue starts.. so how I can resolve this issue?
Ahhh... where is the hot water from the peltiers going? How is it being cooled?
One side of the peltier will become cold, and the other side will become hot. The heated side is connected to the heat dissipation pipe and water pump, and the heat is absorbed by the water, playing a role in heat dissipation.
@@BillMingLabs And then what happens? The water will get hot. There is nothing getting rid of the heat, no hot side cooling.
I have a solution for that. After the water temperature rises, it can be replaced with cold water.😀
After sometimes the water become hot. Then what to do
You could replace it with cold water😀
Run the water throw a radiator in front of the car so wind cools water down
im need buy this pls
I‘m appreciated that you like it😀
I doubt that
Peltier's cooling effect is good
Dont think its working , not real
Peltier is a refrigeration element commonly used in car refrigerators, small refrigerators, and water dispensers. If the fan is not turned on, the temperature can reach -10 ℃.
@@BillMingLabs I know that but I am talking about the heat generated to cooling done, in a closed area it will not help not in car, also the voltage required to genrate will discharge battery, don't you think having a pipe at back to get that heat generated by fan exaust by a pipe outside, also the water cooled can be used as drip onto some grass like a desert cooler will make it more efficient
Great idea! In winter, it can be transformed into a car refrigerator. Hot water pipes can be used for seat heating.
-10℃？
It draws 200 watts of dc power , output is 68.24 Btu/h nice but it's a waste of power lol
Thank you for your comment😀
