Default Evaporative cooling patio misters

Summer's here, and I'm thinking again about those misting nozzle systems
for cooling the patio area. I'm looking into some sort of professional
system, not your $29 toy store variety. I've researched these things
enough to believe that any mister nozzle that's fine enough to work, is
going to clog with mineral deposits from tap water in a very short time.
So I'd like to feed the thing RO water. Anyone installed a system with a
dedicated RO supply? I haven't done the calculations yet as far as GPM.
Any recommendations or feedback on any aspect of this topic is welcome.

I used to go to a restaurant that used those darn things...irritating as
hell! This is Florida, so it gets hot, but they used the things along
with fans, in the evening, in the shade of a covered patio.

Nice. The mister system here in the desert are usually small tubes
and small brass heads. They clog frequently because of hard water. The
better built ones use 1/2" PVC.

Your link looks an easy to maintain system.

Better to use distilled water. Route the drain water from your
dehumdifier from inside the house to your mister.

From the TDS meter results, RO is pretty darn close to distilled. I like
your idea though, except that if it were humid enough to run a
dehumidifier, a mister wouldn't do much good for cooling.

Yes.


I don't think RO will provide enough water pressure?

A whole house filter would help with minerals, etc. and then
occasionally change the filter as needed.

Sample:

It's true I'd need an RO holding tank and supplemental pressure. The
professional misting systems use a compressor rather than relying on
faucet pressure. I will check out the whole house filter, though, thanks!

3 gal/day -- 0.13 gal/hr * 8.4 lb/gal ~ 1 lb/hr

1 lb/hr * 970 Btu/lb /(12000 Btu/hr/T) -- 0.08 T cooling

Probably not enough to make much difference in an outside environment
unless it's a very small area somehow enclosed from any air movement, etc.

I think the problem with many of them is that the water droplets are too

Not to mention that. But actually it looks like dpb's link was to a
nozzle that covers either a 15' radius, or a 3' diameter area, depending
on one's interpretation. I guess if it's the former I wouldn't need 60
of them ...

Micro emitters is the way to deliver the mist.

That's a typo...the 3' should be 30' diameter in the text. We've got
'em at 20' spacing as that's the purlin spacing which was convenient for
piping.

There's a barb connection little plastic one I've never seen that's

See other note on cooling amount vis a vis flow rates, though...

You know I see people and many pro's to try invent something
that is not new. However using mist water to cool is not for any place
that Humidity goes perhaps over 40% RH and we all know that unless
you living someplace in desert that will not be a case.
So in my opinion you are playing with yourself! Sorry

I'm not trying to invent anything. Here's a graph of humidity for the
target area, please tell me whether you think evaporative cooling will
help when the temps get above 100 or so in July and August.

My wife wanted one of these systems. Nothing else would do. I commented
that they caused white from evaporated water, and her comment was that she
hadn't seen white in any of the restaurant areas that we had been to where
they were used.

So, we got some. Fast forward a hundred bucks and a year later. White
calcified markings all over the underside of our new steel awning that looks
like ****. Clogged misters even though we used the filter. Cracked tubing
even though we drained it for the winter.

That one is going elsewhere, out to my shop area, and I would never have
another, or suggest that anyone buy or use them unless it is in a grassy
area, or some other type of area where one would not care if it all got
white from evaporated water.

And yeah, I hear all the arguments for reverse osmosis systems to provide
pure water and all that, but now you're getting up into some real money for
a huhdred or two hundred feet of misters, all the stuff that goes with them,
plus the cost of a water purification system.

Just me, but I would never have another.

I'll never say I told you so, but I may say that I said that would happen.

From what I've gleaned, the better systems have compressors that deliver
the water at anywhere from 250-1000 psi; from what I can tell that seems
to be the primary expense. But of course the piping and nozzles are
higher quality too. The higher water pressure means the water can be
forced through smaller orifices, making for finer mist, which means you
get real evaporative cooling rather than just getting wet.

As far as the water, RO or distilled would certainly eliminate the
mineral deposits you experienced as well as the clogged nozzles that
these things seem to be infamous for. If I don't want to make my own, I
can buy RO water for about 30 cents/gallon, so for $3 worth of water I
could have a cool patio for a couple of hours, assuming 5 gph. I don't
need to run the thing all day every day.
