Roof Sprinkler Cooling

1 gallon of water consumes 8000 btu as it evaporates.

Roof sprinkler cooling.

Each sprinkler assembly has a water manifold pipe a pair of h shaped supports and a sprinkler head connected to the water manifold pipe. 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 water evaporates which increases the relative humidity while reducing temperatures in the microclimate. After the water was shut off the tiles would slowly dry out cooling the roof underneath through evaporation.

Yes water on the roof will help cool it. The principle is similar to the way the human body cools itself with perspiration. 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. Roof sprinklers work by spraying water at predetermined intervals on a roof s surface.

They are unglazed so they would soak up some water. How roof cooling works. One study indicates that water use is around 100 gallons per day per 1000 sqft of roof area. Engineers worked to change the concept of roof cooling from a ponding to an evaporative technique.

An evaporative roof cooling system is designed to reduce the temperature of a roof from 165 f to about 90 f. On a hot summer day it will even provide natural cooling no need for an air conditioning system. 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. The microclimate is the area right around where the sprinklers are located.

A rooftop sprinkler system is not just for fire protection. The embers guard sprinkler protection system has a plurality of sprinkler assemblies connected together in series. This cooling reverses the heat flow through the roof. 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.

These systems provide cooling by spraying the water evaporates and cools the surface. 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. 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. Heat is now transferred out of the building through the roof.

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.
