Low Volume Sprinklers Roof Cooling

Even if cooling by water is.

Low volume sprinklers roof cooling.

This effect creates an effect equivalent of r 7 roof insulation during the day. This translates to at lest 9 7 gallons of water saved by using a gallon of water instead of electricity for cooling. Roof sprinklers work by spraying water at predetermined intervals on a roof s surface. At its lowest tech a roof misting system can be little more than a garden hose set to the mist setting and aimed across the roof.

Heat is now transferred out of the building through the roof. 1 gallon of water can provide 2 9 kwh of cooling. One study indicates that water use is around 100 gallons per day per 1000 sqft of roof area. 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.

Through a drip spray or stream a drip irrigation system keeps roots moist but not soaked using less water than other irrigation techniques. This soaking of the roof and landscape also releases moisture into the air lowering ambient temperatures and increasing humidity levels. It uses about 500 watts for a 1300 sq. As the water evaporates it cools the roof and helps to lower the temperature of the roof tiles and the ceiling cavity beneath it.

On a hot summer day it will even provide natural cooling no need for an air conditioning system. An evaporative roof cooling system is designed to reduce the temperature of a roof from 165 f to about 90 f. This cooling reverses the heat flow through the roof. Areas where water is in short supply.

These systems provide cooling by spraying the water evaporates and cools the surface. The principle is similar to the way the human body cools itself with perspiration. 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.

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. Drip irrigation is a low pressure low volume lawn and garden watering system that delivers water to home landscapes in a variety of methods. A rooftop sprinkler system is not just for fire protection. After the water was shut off the tiles would slowly dry out cooling the roof underneath through evaporation.
