Great job. Very clever and skilled. Congrats! Thank you!

[@BarryKassab]

There are 12v Freon compressors that are more efficient, I’ve researched the Peltier for quite some time and it only works well in direct contact heating or cooling but it’s very bad with air cooling for AC’s. Using the condenser inside the car with a fan might be better than that small fan blowing on the cold heat sinks too. So instead to taking the whole thing apart, get another condenser with contact liquid adapters and circulate the cold liquid. It will also have a quieter fan than the smaller fan. The larger the liquid tank the better and you can wrap it in rock wool or use a small bathroom heater tank and turn it into a cool water container that is cooled by the Peltier. Great project, good luck!

[@Darkipod]

Can you share some 12V Freon compressor model numbers?

[@dannydoolhoff7657]

​@@Darkipodyou may want to start with a search for 12 volt refrigerator compressors. Refrigeration compressors, etc. I would suggest not using Freon. But instead propane. Propane is a cheap readily available item. And it works excellently as a refrigerant. It is also the most environmentally safe refrigerant.

[@hansmuro7355]

​@@dannydoolhoff7657is explosive asf too, I've seen houses completely destroyed because an AC charged with propane, don't tell people to do such dangerous things

[@dannydoolhoff7657]

@@hansmuro7355 there are many units on the market today that use propane as the refrigerant. Many water coolers, ice makers, refrigerators, and freezers now use propane. As a refrigerant it is referred to as R290. "The R290 system has the advantages of a fast cooling rate and high refrigeration efficiency. The average specific refrigerating effect of the R290 system is approximately 52% higher than that of R134a with the optimal charge amount." Propane is excellent as a refrigerant, and works at lower pressures than the old R-12. An R-12 system can easily be cleaned and converted to propane and because of the lower pressures, also extend the life of the system. Yes, precautions are needed as with all refrigerant systems.

This is great. It's possible that you use less coolers and space them apart in different areas inside the cabin to zone the effect over a wider area than ganging them into a single assembly. You've done a great job and it inspires ideas on how to create an efficient setup.

"efficient setup" and peltier? AHAHAHAHHAAHAH thank you for giving me some laugh

[@theoracle6005]

Hi Great work on this project. I have done a similar experiment as well. Try the setup in parallel I think one of the specifications mention that a current limiting resistor may be required to ensure that the device does not heat up, this can also reduce the efficiency of your setup. You should use a variable speed pump so you can improve the scavenging effect of heat from the peltier block. Sometimes slowing the speed of flow will be useful to improve with heat removal. You can use PWM control for controlling the speed of your pumps. With your tubing try to have a parallel path , rather than branching into one serial connection which reduces the output flow to your heat exchanger. Need to mount the cooling side of your peltier inside the air duct work

[@albertnario4877]

I'm going to improve this.. thanks for ldea

[@hamzamouhamed4820]

I did not understand the story of the series, the hex was originally on the parallel, and did the pump increase the speed of the pelleter temperature?

In order to achieve an effective result, you must make the fan draw air from inside the cabin

[@normandothegreat]

Yes, recirculation is best. 👍

[@demostenesramos]

Recirculation and a thermostat to control inside cabin temperature, will help save energy turning on off the Peltiers modules.

[@ka-i]

@@demostenesramos instead of the thermostat turning them all off and all on, maybe switching them to 12v (maximum cooling) down to 6v (less cooling) when the set temperature is reached. This will help to reduce load on the batteries and peltiers, increasing its life span and increase efficiency.

[@derrickenbuenosaires]

@@ka-i I saw an amp draw of 65 amps. That's a crazy load to have on a car battery or am I mistaken ? I would assume it would be more efficient having a vapor compression cycle as it would reduce the load down by alot.

[@ka-i]

@@derrickenbuenosaires absolutely a vapour compression system would be much more efficient. But it needs the skill of making it and also finding the parts to make it. The vapour compression system has a higher initial cost, but is much more efficient than a peltier system. Depending on how they system is designed, they can have a Coefficient of Performance of up to 7, but realistically around 3-6, which still greatly outperforms the current peltier system

[@armandofaso2073]

Albert beast mode. Awesome work. Thank you.

[@KA9DSL]

Hello, peltier junction therm couples are very inefficient. There's only a 30-35 degree reduction, that's not a lot. Very high current draw is one down fall to them. I tried making something like what your creating. The net result was not enough cooling. This will kill a battery or over heat a power supply. I'll stick with Freon based A/C's

[@theclintified]

Have you thought about running it with a pwm to conserve energy? I've always wanted to do this but its good to see you work out the bugs first. It really looks good and well thought out.

[@jgreenan89]

Peltier devices need constant current because when off they begin conducting the hot side back into the cold side making them significantly less efficient. www.ti.com/lit/an/slua979a/slua979a.pdf

[@TheNone724]

yeah if you run peltier modules at 12V you need about same amount of electrical energy than you get cooling but reducing voltage to 6V for peltier module increases coefficient of performance even to 1.8 but then you also need more peltier modules to achieve same cooling power but you use much less electricity

Felicito a este canal por este enorme esfuerzo, yo se bien lo que implica realizar pruebas, armar y desarmar, probar cosas nuevas, trabajé dos años con diversas configuraciones de Peltier tratando de sacar un producto comercial, pero el rendimiento que ofrece es muy bajo, para material didáctico es tremendo, ver que puedo bajar la temperatura a -70 o mas grados es muy satisfactorio con un sistema tan simple, peeeero no tiene potencia para el mundo real, a la misma potencia de consumo de un peltier aprox 60-80w es totalmente funcional un Frigobar a compresor, y un peltier no alcanza a enfriar el mismo volumen del frigobar, pero invito a todos que experimenten por su cuenta, ahí está lo divertido y satisfactorio.

[@PsychoAsian007]

If you had directly added heat sink to the cold peltier side with thermal paste and just made a shroud around it with plexy glass or even pvc for that matter it would have been more efficient i believe.....

I am no expert in peltier cooling, but i thought the 12703 module is the most effiecint between all other peltier modules needing only around 3 amps and its also the coolest clocking around negative 15 to 20 c. While others only hoovers around +1 to +5 c. With that being said, theoreticly the 12703 module should cut your amp consumption in half while offering almost double the cooling.

[@reginaldhorkyiiregorreggie1559]

I'm doing the same thing for fun. a cold side liquid heat exchange works better. add a bigger hot side radiator with more pumps. more insulation. but yah the portable window ac are more efficient pertaining to power. my interest was to use in a car or solar. basically, the only advantage no inverter required.

[@leifhietala8074]

That's really interesting but almost any small compressor based design would be more efficient than this. You could have more cooling for less power consumption. Thermoelectric devices are compact and useful in certain applications but they are terribly inefficient.

Comparing a compressor (that needs oil, refrigerant, and will eventually wear out) to solid state electronics is like apple's and oranges.

[@isettech]

There is a reason those are not in regular use in refrigerators, and more important, in comfort cooling due to the low efficiency. Some modules can have a respectable temperature differential for cooling IR camera sensors for thermal cameras, but high BTU heat transfer applications is not a good fit for the low efficiency of those devices.
