Swimming pool as a heat sink?

I have heard of using a heat exchanger off an AC unit for hot water. But has anyone ever tried to use a swimming pool as a source for a heat exchanger to increase efficiency of the AC system? I am not as interested in heating the pool - though a nice side effect - as I am helping the ac unit cool the house. I live in S. Texas, so anything I can do to help the AC run better is a benefit.
Any plans or lessons learned would be great.
Thanks,
Ed

Pool will get to hot. I'm in VA I turn on my solar panel for two hours a day water temp stays at 86. Add that much heat it will be in the 90 in a few days. Then your efficiency will be worse.

I have heard of using a lake, earth buried, or injected into a well but as posted a swimming pool might be too small.

In order to use a water source to assist your a/c you would need to totally rework the a/c system.
The cooling effect on the condenser needs to closely match the system capacity which requires the installation of a water cooled condenser and a way to control the fan if you wanted to keep the air cooled condenser as well.
There would be no benefit in doing this.

Get a water source heat pump if you wanted a more efficient system.........they are designed for water cooling.
