This is a unique way of providing some free space cooling for your house.
Rick runs the water that he is using for lawn watering through a heat exchanger first and extracts some “coolth” from it before it goes out to the yard.
|Rick’s current test setup.|
His current test setup uses a 20 by 20 inch water to air heat exchanger with a fan that blows air through the heat exchanger to cool it. In this current test setup, it cools the airstream about 10F and provides about 5000 BTU/hr of cooling — about a half ton of cooling.
The energy use is very low — the COP appears to be about 29 (SEER 125!).

Thanks very much to Rick for sending this in.
