3245Re: Nozzle suggestions for roof water spray?
- Aug 20, 2005I understand what you are saying about covering the roof with water
rather than a mist like on a cooling system around an AC outside
unit. But what about a house with a ridge and moderate pitch?
In my work doing industrial cleaning I've worked a bit with nozzles on
shower booms. You have to balance pressure, static head, nozzle
spacing and total gallons per minute to get a shower to work. If
someone has already done the basic design it would help a lot.
I have a family member with an old house and inefficient AC. But, she
is on a community water system where she pays a flat rate for her
water regardless the consumption. Pressure seems fine. Any
suggestions on a roof water cooling system?
Her house must be 60 feet or longer across the main ridge.
By the way, it was built in 1950 on a 125 acre farm. While still
under construction she planted some hardwoods for shade. The workers
laughed at her. Now, those are wonderful shade trees which are a
tremendous help on keeping the house cool. Also, the front porch
faces South with enough depth to keep shade in the summer.
Thanks for any nozzle suggestions.

rather than spray a mist. The misters would have the affect of cooling
the air above the roof rather than the roof it self.

coverage. I'm worried about nozzles clogging, the water in San Antonio
is quite hard.
