DIY Freezing AC : Crafting an Icy Air Conditioner down to -32°C!

100% fake, it's played in reverse, look at the frost on the wood, they have used something like a duster/freezer can then reversed the video, also that little 9volt battery doesn't have the amp's to do that much work 😂😂😂

Butane at 70°f in a closed sytem takes about 30psi to condense and stay liquid. When it condenses it puts off heat and when it evaperates it absorbes heat/ gets cold. You can literally pour condensed butane into a cup and the liquid will boil like a pot of bioling water until it evaporates leaving behind an ice cold cup. The pressure inside the unit must be about 30psi for this to work but the pump isn't pumping 30psi. The pump is creating a differential pressure and that pressure might only need to be about 5-10. Im not sure exactly how much psi it would be but it only needs to raise the pressure on one side and lower the pressure on the other side enough to get the butane to condense and evaporate. While i suspect it would be about 5psi DP it could be even less. This system has all the parts needed for auto refrigeration. It has a power, a pump, a conseror, an orfice, an evaporator and refrigerant. I see no reason to suspect this video is a fake. Thats how AC sytems work.

Great Innovation! The chickens in the background are funny 🤣

You know it's high tech by the chickens in the background.

I think Mr iPoo has EXCELLENT SKILLS -------------- In videography that is....

Very nice. I suggest just one minor change, make the round cold coil a bit bigger so that you can put a can of drink in it and then mount this part vertically and put some insulation around it to keep it cold. And there you have it, a mini fridge for your soft drinks. Great idea.

Normally, the condenser is much larger than the evaporator because you need to remove the heat that is generated by the pump during pressurization as well as the heat that is removed form the air by the evaporator. This is the opposite and will not work long term if at all. In normal air compressors, the high side pressure is 130+ PSI. This rubber tubing would never be able to hold that kind of pressure and the pump being used would not be able to generate that type of pressure either. And running a pump that could generate that kind of pressure would never work with a low amperage 9v cell like in this video. There is something screwy going on with this. could be as simple as the low side (freezing side) being piped to a real compressor beneath the table or whatever this is on.

Thank you.. you are creative 👍

I am a heat and refrigeration engineer! The cooling system is not that simple! A lot of nonsense in this system! (1) this pump does not have enough compression pressure, (2) the injection cable is too short and does not have enough heat exchange from the condenser to the condenser, (3) the system is not evacuated to remove the moist air inside. never bring the temperature below 0 degrees Celsius, (4) assuming there is ice precipitation like the video, the temperature will never drop to negative like that! Conclusion: This is the skill of the video maker

Really sweet! GR8T job. Those background sounds really upped my hunger level :face-fuchsia-tongue-out:

Your invention is very nice, I tried to make a cooler with peltier plate ,but it consumes too much current. I am going to buy a radiator and connect a capillary tube and a condenser

Would like to have seen the condenser temperature. And of course the pressure drop across the capillary would have given us the complete story...

Could someone please give us an indication about how much refrigerant is put in the system? Do you have to have sufficient to fill the warm side coil, or is a just little enough? TIA.

wow... impresionante,, que ingenio!! Muy buen video y trabajo. saludos

You can use those air duster cans for propellant. its just good old R142a

Muy buen video, lo felicito por, gracias por compartir sus conocimientos!!!!... 👍👍

Wow - what a great project. I would love to make this with my kids in the holidays. Big smiles and thanks from Sydney - Dave

I'd like to know how long it takes for the ice to form on the surface. In the video, there's an overlay effect called compositing, both in the fan's audio slowing down due to battery discharge and in the video itself. Could you tell me how long it takes in real life? Thank you!

This is incredible.

I have one of those pumps from a broken Keurig they get a pretty good low pressure. Pretty sure that pump can handle butane. I was wondering how you would have the expansion cycle, seeing the larger hose used as such was nice. Wonderful demo for refrigeration.
