ABSTRACT:
A roof-mounted shade assembly for reducing solar heat gain includes an array of fabric panels that are tightly stretched between upright support posts in an operative position overlying and spaced from the roof of a building structure. Several spray nozzles periodically discharge water spray in the form of mist or fog into the space between the fabric panels and the building roof. The fabric panels become saturated with water spray, and fog/mist water droplets are in heat transfer contact with the roof surface and with the wet fabric panels. Thermal energy from the building structure is transferred to the surrounding atmosphere by convection and evaporative cooling as wind currents sweep across the wet fabric panels and the wet roof surface. The water-absorbent fabric panels simultaneously screen direct solar radiation and function as a thermal wick for transferring heat energy from the building structure.
