Low Volume Sprinklers Roof Cooling

This translates to at lest 9 7 gallons of water saved by using a gallon of water instead of electricity for cooling.

Low volume sprinklers roof cooling.

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. 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. Even if cooling by water is.

Through a drip spray or stream a drip irrigation system keeps roots moist but not soaked using less water than other irrigation techniques. If it s not sealed in plastic and evaporates you consume an additional 8000 btu as that gallon evaporates. 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.

Areas where water is in short supply. This cooling reverses the heat flow through the roof. 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. 1 gallon of water can provide 2 9 kwh of cooling.

On a hot summer day it will even provide natural cooling no need for an air conditioning system. 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. A rooftop sprinkler system is not just for fire protection. Roof sprinklers work by spraying water at predetermined intervals on a roof s surface.

This effect creates an effect equivalent of r 7 roof insulation during the day. One study indicates that water use is around 100 gallons per day per 1000 sqft of roof area. These systems provide cooling by spraying the water evaporates and cools the surface. 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. This can be done day or night due to the low humidity that is common. 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. We have an evaporative cooler and ac but the humidity is low enough about 25 days a month to stick to the swamp cooler.
