Roof Evaporative Cooling System

In low humidity areas evaporating water into the air provides a natural and energy efficient means of cooling.

Roof evaporative cooling system.

1 gallon of water consumes 8000 btu as it evaporates. 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. This cooling reverses the heat flow 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. These systems provide cooling by spraying the water evaporates and cools the surface. What roof cooling is and does a network of computer directed ultra violet resistant uvr pvc piping which showers short cycles of water mist onto the roof at intervals all treated parts of the roof are wetted as wet zones dry and cool the other zones are re wetted in cycles. Areas where water is in short supply.

The 15 to 40 f cooler air is then directed into the home and pushes warmer air out through windows. Evaporating cooling systems are among the most economic and environmentally friendly air conditioning systems on the market. This effect creates an effect equivalent of r 7 roof insulation during the day. Evaporative coolers also called swamp coolers rely on this principle cooling outdoor air by passing it over water saturated pads causing the water to evaporate into it.

Evaporative cooling is a ducted cooling system that is situated on top of your roof with ducts connecting to key rooms if not all of them in your home to distribute cool air. These systems filter and cool natural air and circulate it throughout your home using a system of ducts. 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. Evaporative cooling is the most common form of whole home air conditioning in melbourne because of it s incredibly low running costs it s the cheapest form of ducted cooling and you can leave your doors and windows open.

Yes water on the roof will help cool it. The cooler s metal surfaces are coated with a polyester powder finish that provides a beautiful appearance and helps protect against. Heat is now transferred out of the building through the roof. One study indicates that water use is around 100 gallons per day per 1000 sqft of roof area.

Thanks to its natural water based processes this system does not dry out the air in your home or emit toxic gasses.
