Hello everyone! Summer is coming and instead of buying a $200-$400 air conditioner, I'd figure I could try a DIY version. I came up with a schematic (attached below) and how I think it would work. I feel like I'm missing something blatantly obvious that will make it not feasible. Wondering if you could take a look and give me some pointers? Essentially: -Tank of cold water supplies axial fan with cold water to blow via copper tubes. -Water is sent to a cooling tank that has an enclosure. -The enclosure contains separate water and an air suction line. -The air suction line will eventually turn on creating a vacuum. -The separate water will turn into ice. -Ice will cool water. -New cooled water will return to cold water tank. Please excuse my handwriting. Hopefully it is legible. I suspect the system is not as efficient as an actual air conditioner but it only has to cool 1 bedroom. It is also cheaper this way. Thanks for any input.
