Good evening! Your system as I understand it is a certain closed system! How do you replace the liquid? And what is the best liquid to have a good efficiency
I used a meat suringe to fill the hose lines with 50/50 dexcool coolant. try to use better pump and bigger gauge copper piping. I made a better one but not ready for the public eye yet. lol.
anyone who makes this. just letting you know that I made this very basic setup to display what I've been working on for 8 years. I went through a lot of peltiers before I got the formula right where it didn't explode, completely freeze, evaporate fluids, fires, burn out power supplies, over heat, and ect.... I spent a lot of money working on a bunch of ideas but now have made 3 a/c peltier machines that run off 12V 450W with a new formula coolant liquid I've been working on to be efficient enough and safe for the environment at the same time. I will be releasing a video with these new ones very soon. I'm glad this video was popular.
its hot side is over heating the module. your heating the cooling process to rapidly. I have to use arduino boards to even out the cooling process. your peltier are burning out because they are too hot. find a better cooling unit for the peltier.
it took me 8 years to finally get it right. what you see in this video is just a demostration or a small concept of what I really am making. the unit I built now drops down to -26C before I turn on the fan.
scarysamons I was using a heatsink with fan. Which not exhausting hot air. Mean it's controlling hot side. Why should I need more cooling system on hot Side?
Nice project but you should have someone else hold the camera. The video is shaking and moving around too fast from one object to another , difficult to follow!
not a concept, i built a bigger one that cools my house down to 42 degrees on a 98 degree day, so eat that concept. I also don't share a lot because I copywrited this and patent this idea. so yeah bye.
Anyone who want to make AC peltier should very very very serious working on its heat dissipative system so you might build a good efficiency AC peltier otherwise you just build a useless things with crazy electric waste consumption..
no the problem is that I live in a 1950's SEARS Model Homes and it's made of all metal, absolutely everything is metal. So when it is summer timer in Illinois it gets really hot in my house because it turns into a oven. the SEARS Model homes have 13inch window space so theres no actual room for a real a/c unit in the window. I do live near a walmart but that won't help me. I built 18 different models of peltier a/c's units before I got it right. I'm running my final tests on it and will be releasing it the public soon. What I built will save people so much money on there electric bills.
Somebody correct me if I'm wrong. Assume a 2x2x2 metres room (bit less than 6x6x6 foot), that's 8m^3 or about 9.8kg of air. Assume fans that push 3 m^3 of air / minute (around 100 cubic feet / minute). That's 0.05 m^3/s. Assume we use a huge 20x20x10 cm heat sink on the cool side and ignore the hot one. That's 0.004 m^3. This heat sink has about 0.08s to transfer heat before the air exchange around it (simplified). Let's assume a 100W Peltier module and half of it is used for cooling. For one volume of that heat sink with this fans the module can transfer 50W * 0.08s = 4 J = 0.04 kJ of heat. If we were to cool the air by 20 degrees we'd need: air mass * air capacity * temperature delta = 9.8 * 0.7 * 20 = that's 137.20 kJ. Our hypothetical Peltier AC would lower the whole room temperature by 0.005 degrees each 2m40s in conditions of perfect isolation. So about 0.11 degree each hour. It would take it a bit over 9 hours to lower the temperature by one degree. The air blown out of this thing would still be hot, as in: no difference to touch. This guy's unit is way less capable and his room isolation is non existent because he releases the heat back to where it came from. It would be actually more effective to cool that room with a bucket of ice.
