DIY Air Conditioning Fan
I recently saw this video of a floor fan converted into an air conditioning cooler. Ice chilled water in a bucket is sent by a pump through a coil attached to the front of the fan.
The fan pushes air across the coils, exchanging the cold from the water to the air, and the water returns to the bucket to get cold again.
It was really well done, but ended up with a bucket in one spot, the fan in another, and hoses and power cords stretched in-between.
I wanted to build one that works on the same principals, but also looks nice in a home office.
