Need opinions on Pool Water Chiller idea.
I was thinking about making a pool water chiller by burying a coil of pipe underground. Water would flow from pump, through buried coil, and then back to pool. I previously made a solar heater using 200 feet of 1" black plastic pipe.
One question is how cool is it about 4 feet under my yard? I have about 5-6' of sand over a hard clay layer. I guess I'd want to get the coil right down on the clay for max cooling. I don't think plastic pipe will exchange enough heat. Do you think 50' of 1/2" diameter copper coil would do the job?
Pool water gets from 86 up to 92 at times when it's really hot. I'd like to drop it by 5-6 degrees at least, or it won't be worth the effort.
I was thinking about driving a 1" PVC into the ground about 5', flushing the dirt out with water and dropping a thermometer down there on a string to see what the temp is below ground. I'd guess about 75 maybe?

Lol Bill is NOT worried about aesthetics. Ever. But I like the train track idea.
12x24x4 oval above ground.
Oh, in that case, a couple of 20# bags of ice should do the trick.
I direct the pool water through it in the winter during the daylight hours to warm the pool.
In summer, I run the pool pump at night to radiate the heat of the pool water into the cooler air.
It's worked for me, my pool stays at about 86 degrees.

You need to learn more about physics. For that to work Venus must be in retrograde during a waxing gibbous. Unless you know a good shaman...
Winner, just make a fountain or waterfall, it really works, wife and kids will luv it too, super easy and cheap.
I set up a house like this with six water cooled A/C units. Heated the pool in the winter but not so sure about summer. Aireation works great at night and may be your best bet.May need to add extra water.
It might work if he could the cooling pipe to the aquifer?
Great, now I'm gonna have to hire a shaman for my pool remodel!
I do direct the return upwards to create a fountain effect, and it helps a bit.
Would a fan blowing on a car radiator cool the water inside even if the ambient temp was above the water temp?

Your idea will work.....just need a couple miles or more of underground tubing. My brother has some sort of underground heating/cooling for his home, many many many miles of underground tubing with some sort of chemical liquid.... works great. A constant 72 all year. Not cheap and not sure what the cost return period is.
Start buying hoses now, they are on sale at Lowes, may need more than a few.....
Of course not. Aren't you a chemist or something? Didn't you have some exposure to heat transfer principles?
