yes spraying water on the coil could make you use more water than
necessary. I was agreeing with you that evaporatively cooling the
ambient air would improve the condenser performance, just using the
lawn sprinkler as an example.

I have a salt corrosion problem here, all aluminum spinefin is the
best, inherently superior to any type of corrosion protection coating
applied to a copper tube, aluminum fin coil.

If they wash uncoated aluminum fin/copper tube coils frequently they
last longer.



The Rheam unit with copper coils I talked about didn't use much water.
Most of the water was caught in a pan just like a swamp cooler. Just a
little was drained off through the little trough to keep the mineral
content down. Just thought that a swamp cooler sitting on the ground
next to the condenser would be a good compromise for an aluminum coil
unit. What puzzles me is that I never see it done.

Another item I thought of was to put a small evaporative unit to
somewhat cool the attic. That would more or less eliminate the ceilings
as a heat source.
