You can usually make a new or existing roof cool by selecting the appropriate surface.

Roof surface evaporative cooling.

These systems provide cooling by spraying water on the roof surface. During a shower or artificial watering the porous construction material of a roof absorbs some water depending on its water holding capacity. Motor not included model 5000 sd 684 28 684 28. In warm climates evaporative spray roof cooling esrc systems not to be confused with roof ponds.

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 better way to cool the roof is to change its color. This sets up a temperature gradient between the inside air and outside roof surface resulting in loss of heat from the inside to outside. They are simple and appear to be effective but would not be a good choice in areas where water is in short supply.

Heat is now transferred out of the building through the roof. Set your store to see local availability add to cart. Evaporative cooling is one of the well known techniques to cool the roof surface resulting in the reduction of thermal load of the building. 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.

A roof with a clean smooth bright white surface can reflect about 85 of incident sunlight and emit thermal radiation with 90 efficiency. One study indicates that water use is around 100 gallons per day per 1000 sqft of roof area. This surface will be only 9 f warmer than the outside air on a typical summer afternoon. Cool roof coatings are white or special reflective pigments that reflect sunlight.

This cooling reverses the heat flow through the roof. There are many types of roof systems available but the surface exposed to the sun is the one that determines if a roof is cool or not. Coatings are like very thick paints that can protect the roof surface from ultra violet uv light and chemical damage and some offer water protection and restorative features. The water evaporates and cools the surface.

An evaporative cooling system consists of an intake chamber filter s supply fan direct contact or indirect contact heat exchanger exhaust fan water sprays re circulating water pump and water sump. The evaporation of water causes cooling of the roof surface. This effect creates an effect equivalent of r 7 roof insulation during the day.
