Pool cooling in muggy se missouri

[PoolDoc]

I can't find "Gacier system" on Google, so I don't know.

But, in general, evaporative cooling systems don't work when it's "muggy", because when the humidity is high, the evaporative systems can't evaporate some of the water to generate a cooling effect. It's possible to use an evaporative type spray system, like a fountain, to 'cool a pool' at night, by simply cooling the water by warming the air around the pool. But to have much impact, you have to spray a LOT of water up into the air, and have some air movement -- but not wind -- at night.

He's talking about these things: http://www.glacierpoolcoolers.com/?page=residential

I was looking at them last summer; but decided they were just too darn expensive ($1500 plus installation).

From what I understand it uses a sump pump and fan to cool the tubing inside.

More importantly, those units are only practical where the dewpoint STAYS below 65 degrees. Largo, FL (dewpoint currently = 74) is not one of those places, and neither is Chattanooga, TN ( dewpoint currently LOW at 68, after weeks above 70). The original poster is apparently from St Louis, MO(from IP address) where the dewpoint is 70 right now. That unit will not work well in ANY of those locations.

On the other hand, in Phoenix (dewpoint = 51) or Las Vegas (dewpoint = 41), those using could be used to create a COLD pool.

I also live in the STL (S/E Mo.) area, and even tho we just got our new pool up & going, I know that next year we will have the same problem that everyone else who lives in this "nearly uninhabitable in July & Aug" area have, pool temps in the upper 90's. Majesticman also asked about heat pumps. Is this a viable option to heat & cool an AG pool in this area? I would like to open our pool in late Apr & keep it going through Oct so would need to heat early & late & cool in July & Aug.

It's possible for a heat pump to cool a pool, but I don't know whether any of them are set up to do so.

Otherwise, you can run a fountain or a solar heater at NIGHT, and you'll get some cooling, but I have no idea how much.

I was going to suggest a solar panel, but Ben did it first. If you install a solar panel and run it at night, it acts like a car radiator to dissipate heat. Since heat rises, it will work even if it's muggy, as long as the air is cooler than the water.

Carl, do you know if anyone has ever done this, and reported results?

I really have no idea how well it would work . . . and the complications aren't simple.
