It can decrease the AC energy by 20%. I've tried it with rainwater.
Groundwater tends to build up mineral sediments.

With some misgivings, I'm trying something similar this electric
period. I don't want to corrode things, so I purposely chose the
hottest months and am being conservative with the water. I'm still of
the opinion that direct cooling of the compressor or scroll could be
nearly as effective without the danger of corroding aluminum fins or
starting pinholes. I plan on checking my own setup next week to see
if there are any early indications of problems.

Cool! I'll test mine by created something to dribble a bit of watter
on the top of the heat exchanger fins. Let me know what you
discover.

I've seen it done on some air conditioners to disastrous effect.
You have to be sure that you have mineral free water or it'll
build up on the heat exchanger. The more mineral laden (hard)
your water is then the more dramatic the mineral deposits will
become.

Ever wonder why the major manufactures do not offer one?
Our local electric utility offered a heat exchanger called a "Heat Tap"
Marketed under " Hot water from cool air." Lasted less than 6 months in the
field. I know that they tested the unit before selling them. The exchangers
leaked eventually and you got water in the freon..... All that were
installed were removed by the utility before a year was out.
I had a cooler pad in front of my old Tappan condenser. Helped lower the air
temps but was a pain in the XXX to keep clean. I ditched the idea after the
first season.

Yogi Goswami tried that a U Florida, with a 20% gain, but that seems more
complex and less effective than just trickling water over the hot fins,
which can help more on a humid day.
I put a 55 gallon plastic rainwater drum under a 5K Btu/h window AC with
a hose to a gutter fitting. A $10 10 W Harbor Freight fountain pump moved
water up from the drum and into a plastic tube with some holes wired to
the top of the hot fins. A hole in the bottom pan of the AC let water drip
back into the drum. The total power dropped from 1050 W with no pump to
950 with it, and the cool air temp dropped from 55 to 45 F.
The window AC is about 7 years old. Efficiencies have improved.

| Sounds like cleaning the heat exchanger is the main issue with
such a system. I like the example of using a self-contained
system with rain water. I remember my brother lived in Lubbock
Texas once and he had what he called a swamp cooler for his house
instead of an airconditioner. He said that alge was his worse
problem.

I've sprayed our heatpump/AC unit with the hose on hot days..
It does make it blow a bit colder air,for a few minutes..
it also helps clean the bugs,dust and grass clippings out. ;-)

| It works but you almost have to used distilled water or you get bad mineral
buildup, which ends up making things worse.

I've never seen much algae build up in a running evaporative (swamp)
cooler. Around here the mineral deposits can get thick enough over
time to decrease air intake, though.

Don't most window mounted AC units use a system similar to this?.
Water gained through condensation runs into the pan at the bottom of
the unit, is picked up by the rear fan, and is splattered onto the hot
coils.

I think it's a good idea since the water is clean of minerals. But,
where I live we rarely have enough humidity for the idea to work.

| Contary to your situation we sometimes have a humidity so high but no
temperature so the AC doesn't want to run and remove the humidity. I have
actually fired up my NG fireplace in mid summer to dry out the chimney pipes
and get the AC to clean some moisture out of the house.

My parents used to live in Louisiana. It's always wet so they would
run the AC some in the winter just to clear out the humidity. Of
course, it's much warmer there than where you're at.

| Well, I got my first bill after I put my misting system in place.
This worked out well because the last two months have been
mostly the same weather wise. If anything this month has been hotter.
The month with the mister in place showed a 14percent reduction
in my energy usage. Now to handle the cleaning problem...
