I wanted to make this for my camper. But I don't know if its efficient to be charged with campers alternator. I have a second battery with an isolator.
really nice design and idea you got there buddy! can be both a heater or a cooling device, would love to see it installed so the heat side can not mix with the cooling effect and do a hourly record of progress. and then same for heating set up, excellent idea!! those will sell good for boats, motor homes,etc.
My plan is to buy an Adafruit 12v 5A module with a pre-installed heat sink and fan, and put a computer heatsink on the other side, on one of the locker doors that gives access to the inside of the dash and the gunwales to vent heat out through the gunwales, since there are rod holders are installed that work as vents. The boat is a 26 foot (7.92 meter) custom sport boat and the cabin is maybe about 12 feet (3.6 meters) and doesn't have standing room, but it's good for dodging storms and storage, so I figure a small peltier may be able to cool it nicely.
Alan,1. how many TEC did you use? And 2. would it be effective with 75 amp 12 volt system? 3.In how much time did it drain your batteries? Thanks in advance.
Cool video, and love the idea and design, but I thought the calculation that was done is for the hot side they use that formula in heat decepation in electronics, not the cold side. But still it is beautifully done
Thx for ur idea im attempting to make 1 for my room in stead of 1 peltier module i use 2 cause im cooling a bed room now im planing to build it tempreture adjustable and the fan is speed adjustable and run on 24 volts or 12volts to conserver energy cause im just in a small apartment so i cant shove 1 big air conditioner in my apartment
Another idea is to use a PC water block and run open circuit water through it but PC parts aren't exactly designed for saltwater, or any non filtered water for that matter, a electric pump is required, and it has to be run through the hull or in my case probably through the cockpit and over the gunwale. Also, I live in Florida so the water is often very warm (98F/36C last summer) and may not get me very cold air.
Alan... Can you please name the what tec unit you are using i means its rating.... Like tec1 12706 is most commonly available in market...can you tell me efficiency of tec1 12706, if you know
Peltier max efficiency is %40. With 20w energy input you get an extra 7% more efficiency. With 5V 4A peltier cooling support, applying extra cooling to the heated surface is sufficient. Some special product developments mention about 60%. However, such modules are hard to find as they are very high in price.
If you used a waterblock on the hot side, your efficiency will be much better, and you wouldn't need to cut a 12" hole in your wall. Being that you are using this on a boat, you have an ideal source of ambient temperature fluid to pump through the block, wouldn't even need a radiator.
how you get the extra i out of aluminum
u could use two 12v computer power supplies connected in series ? what is the power of peltier ? 350w ?
Thanks for this video! I learn something new about air conditioning issues
So how's the 3 module cooling? Is it noticeable in the room or some kind efficient if used in a small room?

How many pliers of 12715 can be cooled to room 10 by 10 feet and how many 12706?
where did you purchase it?

Good Video, This is a nicely built Peltier cooler. Can you please tell me where you purchased? Thank you

Where to buy this unit ?
should I put that on window...?
