Roof Sprinkler 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.

Roof sprinkler cooling.

Roof sprinklers work by spraying water at predetermined intervals on a roof s surface. On a hot summer day it will even provide natural cooling no need for an air conditioning system. 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. 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.

An evaporative roof cooling system is designed to reduce the temperature of a roof from 165 f to about 90 f. Heat is now transferred out of the building through the roof. Cooling with liquid water running off from a sprinkler is not efficient but evaporative cooling from a small amount of water like a periodic sprinkle is very efficient. Each sprinkler assembly has a water manifold pipe a pair of h shaped supports and a sprinkler head connected to the water manifold pipe.

The microclimate is the area right around where the sprinklers are located. This cooling reverses the heat flow through the roof. The embers guard sprinkler protection system has a plurality of sprinkler assemblies connected together in series. A rooftop sprinkler system is not just for fire protection.

1 gallon of water consumes 8000 btu as it evaporates. Areas where water is in short supply. How roof cooling works. Some of the water evaporates which increases the relative humidity while reducing temperatures in the microclimate.

Engineers worked to change the concept of roof cooling from a ponding to an evaporative technique. Yes water on the roof will help cool it. When rooftop sprinklers are activated they spray water high up in the air which lands on the roof trees and other surfaces that are within range. These types of systems can also be set up to operate automatically either on a timer or connected to an automatic temperature sensor which triggers the system whenever it gets too hot.

Some of the owners would run a pipe down the peak of the roof and occasionally turn on the water letting it soak the tiles. 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. They are unglazed so they would soak up some water.

Ember s guard rooftop sprinkler system this multipurpose portable tool is primarily made to protect your property from ember attack but can also be used as irrigation for garden and lawns as well as cooling your roof or misting your patio and as an entertainment for kids on a hot days of summer.
