I have a question about cost of water cooling vs air cooling. Specifically if I was to install a heat exchanger setup using my municipal water, which would cost $6 per CCF (782 gallons). The water is COLD, colder than I need. I could make use of electronic flow control with a temp controller to minimize water usage.
How many CCF's would I be pulling down per day to cool a 11 light setup?
In the future I'm gonna have a couple geothermal loops dug in, so I can pump water in one side and it will always come out cold on the other. No chiller needed, just a pump and a heat exchanger.
I'm sure Shrapnel will absolutely HATE this idea though!
Ground water is usually below 65 degrees so I think your on to something here. I'm chompin at the bit to get going on this venture so let's keep the ideas a flowing as we spark up another inspirational doobie and brain storm.

Hmm, I have free access to a backhoe though, and about an acre of grass I can do whatever I want to. Sounds like a good summer project, dig some trenches and lay some coils of tubing out horizontally instead of paying a driller $20K. My only cost would be backhoe fuel and the tubing, which couldn't be more than a few grand. Wow at that rate it's cheaper for me to dig in coils than it is to buy a chiller.
Hmm, gears are-a-turnin!
