Low Volume Sprinklers Roof Cooling

A rooftop sprinkler system is not just for fire protection.

Low volume sprinklers roof cooling.

Also called an evaporative cooling system a roof misting system lowers surface temperatures by spraying an extremely small amount of water across the roof allowing the water to cool the roof as it evaporates. Because it is designed to provide gentle water distribution over a large area it is a perfect means of keeping your landscape green and lush. One study indicates that water use is around 100 gallons per day per 1000 sqft of roof area. We have an evaporative cooler and ac but the humidity is low enough about 25 days a month to stick to the swamp cooler.

Once the evaporation cools the roof to say 100 degrees an additional gallon of 70 degree water can only warm up to at most 100 degrees a 30 degree increase which would only consume 30 x 8 34 250 btu. Roof sprinklers work by spraying water at predetermined intervals on a roof s surface. The roof saver sprinkler kit is an exterior fire prevention system designed to wet roofs gutters decks surrounding trees and shrubs making these fuels less susceptible to ignition. After the water was shut off the tiles would slowly dry out cooling the roof underneath through evaporation.

As the water evaporates it cools the roof and helps to lower the temperature of the roof tiles and the ceiling cavity beneath it. This translates to at lest 9 7 gallons of water saved by using a gallon of water instead of electricity for cooling. This soaking of the roof and landscape also releases moisture into the air lowering ambient temperatures and increasing humidity levels. Even if cooling by water is.

It uses about 500 watts for a 1300 sq. Through a drip spray or stream a drip irrigation system keeps roots moist but not soaked using less water than other irrigation techniques. Heat is now transferred out of the building through the roof. On a hot summer day it will even provide natural cooling no need for an air conditioning system.

Drip irrigation is a low pressure low volume lawn and garden watering system that delivers water to home landscapes in a variety of methods. The principle is similar to the way the human body cools itself with perspiration. An evaporative roof cooling system is designed to reduce the temperature of a roof from 165 f to about 90 f. If it s not sealed in plastic and evaporates you consume an additional 8000 btu as that gallon evaporates.

This can be done day or night due to the low humidity that is common. These systems provide cooling by spraying the water evaporates and cools the surface. This effect creates an effect equivalent of r 7 roof insulation during the day. Areas where water is in short supply.
