ill suggest using a capilary tube sunk in coolent in water cooling system

😊I like that saw very much

Thank you for your comment😀

Thank you for watching and commenting😀Use a larger water tank and put it in a foam tank for better results👍

Thank you for your comment. I will improve next time😀

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.😀 -------------- More videos: www.youtube.com/@BillMingLabs

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.

The total power is approximately 200W😀

@@BillMingLabs with that power consumption and not gonna cool your room better buy a 4500btu AC split with 260w power, indonesia country sell those unit some years ago LG hercules mini 0,5hp unit 4500btu, some panasonic brand inverter AC unit can set to run only 200w at lowest setting

Thank you for watching and commenting😀

Thank you😀

The water pump is very small, 5V, 3W, 200L/H. Thank you for your comment and for the like. Have a good day😀

Thank you for your comment. Have a good day!😀

Thanks for your compliment. Have a good day 😀

I have posted the required materials to the online community😀

@@BillMingLabs THANK YOU SO MUCH!!! Did you know that I will use this for my research? THANK YOU

@@BillMingLabs But can you provide a list? Like the specific names of the components? Thank you

Thank you for subscribing😀I intend to continue refining it. After enhancement, it should fetch a good price😁

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?

The thermometer on the left detects the temperature of the water, and as long as the Peltier is working, the temperature will rise. The thermometer on the right detects the temperature of the air outlet. The middle thermometer detects the ambient temperature and can set the starting temperature (such as 26 degrees) and stopping temperature (such as 25 degrees). For example, if the ambient temperature is higher than 26 degrees, it will start, and if it is lower than 25 degrees, it will stop, thus achieving constant temperature.

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😊

It depends on the weather conditions. I put it in the third row because my car doesn't have a separate air conditioning outlet in the third row. I am trying to create a more powerful air conditioner. Welcome to follow my new video. Good luck😀

@@BillMingLabs can you build bigger air con like this to cool down whole car?🤔🤔 If you do I would buy it😀😀

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😀

Generally speaking, the side with characters is the cooling side, and the other side is the heating side😀

Um you test it hahahha

Thank you for watching and commenting. By the way, I wouldn't say I like high humidity😂. Have a good day!😀

Thanks😀

Thank you for your suggestion. Have a nice day😀

It has a certain effect in small spaces that are not particularly hot. Increasing the number of Peltier devices, increasing the capacity of the water tank, and using ice water will have a more significant effect.

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.😀

You could replace it with cold water😀

Run the water throw a radiator in front of the car so wind cools water down

I‘m appreciated that you like it😀

Peltier's cooling effect is good

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.
