You use a heatpump, which has a refrigerant loop, with a heat exchanger to the pool water. Heatpumps can work in both directions. The "hot" side is after the compressor and the "cold" side is after the expansion valve. If you want to cool the water, the heat exchanger to the pool water will be on the "cold" side and the "hot" side will release the heat to the outside air. Reverse the situation and the heat exchanger will be provided heat on the "hot" side and remove heat from the outside air on the "cold" side.

They also say that they can "accommodate" salt water pools, but the pump will need to be "washed off" every "couple of weeks. They have a one year warranty on their many sized pumps.
That made me wonder....hmmm. I hadn't heard of pool cooling and I am old but I do try to keep current. I like to understand the "science" of things. Perhaps someone here can explain how you cool a pool other than to blow air with a fan on the circulating water.
After having T and D in our yard the last couple of months installing a pool, I am in awe of their expertise and their high standards and would think they would know about pool cooling.
