An off the wall question but I'll ask it anyway, given that I've been tempted to call the ice truck to dump a few dozen 10kg blocks into mine.
Has anyone seen a system where the water is refrigerated, I assume as it passes through the filter pot. I don't think it would be too difficult to put some refrigeration coils in there to allow the circulating water to pass over them. I would think it may be a standard thing in the ME where pool water temperatures must be almost unbearable most of the year. I've heard that some large hotels pass their pool water through their central air conditioning system, but I don't know if this results in cooler pool water, or a system like that does the opposite and extracts the coolness from the pool water for room air conditioning purposes.

Just off the cuff Pete: unless you have an existing unused source of cooling, it would be an expensive operation. Need to work out how many BTU`s of cooling required to lower the volume of water I degree, and then the energy requirement can be calculated.

Here in Doha it's an absolute necesity in the Summer months, especially for pools without any shade, but in the Winter even here the water gets pretty cold on its own. Although as Nereus points out cheap it isn't and maybe prohibitively so for a private pool.

Many years back, whilst working in Kuala Lumpur, I stayed in an apartment that had a covered pool with 3 sides 'open' to the breezes etc. It was always a joy to swim in and was never too warm.
So - this is a little extract from a current design I am playing with.............

The long 'open' side faces east and the 'closed' side is to the west - so the morning sun (not so relatively hot) will be well over the roof cover by the time I surface - and the pool will remain in the shade for the rest of the day

Yes, I was just trying to post that Pet! A good sailcloth" type of awing might be worth looking at. It would also reduce the evaporation.
A house near me has built a wooden frame and has installed 4 or 5 fabric panels that can be extended individually via a cord/pulley. Imagine roman shades that are horizontal rather then vertical. Looked quite simple and effective.
Some good ideas about covering. I wish I would of thought of it when the place was built. Really difficult now with existing structures, underground tanks, plumbing, walls etc. Doable, but very major construction. Pete

This all brings to my mind the tensioned shade or awning. A couple of poles anchored well and a tensioned shade placed over the pool. Those types like Costa something has put up at some houses. Heck of a lot less costly than fixed construction over pool.
Sure to understand the problem though as my pool is getting over 30 degrees and warmer than outside air for morning swim after my run than the outside air. Like swimming in a bath tub.
Yes, it will lose water, that`s how it works: evaporation! BUT, it will only work if the relative humidity of the air is low. With high humidity I doubt that there would be much effect. How can they claim that it costs zero to operate when it is necessary to run the filter pump?

That was my point.

Well, probably referring to "additional costs" - you would after all be running the pump without it. The loss of water however could be a significant cost I guess.
Had not thought about the humidity level........

1. Any kind of cloth shade or awning, or even a metal awning, is russian roulette over where I am. Our storms arrive off the Gulf with very high winds. If not retractable, and someone is here to retract it, it will be in shreds I'm afraid.
2. We have three very big shade trees all lined up west of the pool in a row as close to the pool as practical. Smallest is about 25', middle 35' and right 50' at present and still growing. They only shade the pool from about 1500 hours on. They help you avoid a sunburn in the mid/late afternoon onwards, but not keep the mid-day sun off the water.
3. I don't think that mist thingy is meant for the tropics like this. The city water source that would be doing the misting is already at about 28C this time of year. You can take a hot indoor shower without turning on the hot water. Pete
Edit: Just re-read #3. That may work. Not using outside source water as I first assumed.
