Has anyone every tried building a homebuilt Air Conditioning unit using cold water as the source?
I have a spare surface well that was replaced by an artesian well many years ago. Its a 4' concrete well about 17' feet deep, with about 3' sticking out of the ground. The vleev varies but I usually have a minimum of 4' of water in the bottom.When it was built we bedded it in a truck load of crushed rcok to get some storage as the surrounding soil is clay. I used it for about 10 years and never ran out of water. I also ran 2 lines from the well to the basement. For much of the year the basement is below the water level in the well so I dont need much suction lift. The water temp is never above 50 degrees, which made it chilly when I had to install the foot valve.
What I would like to do is install an air handler in a bedroom and circulate cold water through a coil to cool the room. Rather than build the handler up from pieces I would like to find something commerically built but I dont need much more than 10,000 BTUs/hr and the commercial air handlers I find are much larger. Ideally I would like to find something like the head unit from a split system but I expect that the coil sizing is a lot smaller for refrigerant than cold water. I have hot water baseboard and not a lot of room for ducts so an external handler with ducts is not a good option.
One concept was to install a split unit and submerge the condenser in a tank of water fed from a well but getting things water tight would be tricky. I expect if I did that, I would need to install a coil in my well and use a circulating fluid so the aluminum fins wouldnt corrode from constant fresh water.
Any folks have suggestions?
