Abstract
Evaporation is nature's way of cooling. By spraying a light film of water in the form of a mist for thirty seconds, then turning the sprays off for five minutes while evaporation takes place, the roof temperature can be reduced from 1650o to 880o. Roof air conditioning load is reduced by 85% to 90%. The cooler roof also protects and extends roof life.
My presentation today will cover an old, square foot, and generally speaking, it will old technique -- one that has been gaining in show a payback of 18 to 24 months. As one prominence in recent years, due to the energy plant manager said, "I pay more than that shortage and the increased cost of electricity each year, just to sweep my floors." -- Solar Roof Cooling by Evaporation.
