Abstract: An evaporative roof cooling system for placement upon a roof surface exposed to relatively high levels of solar radiation. The system includes water distribution piping and a plurality of mist/spray nozzles positioned on the roof surface for supplying a uniform spray of water thereover to lay down a substantially uniform thin film of water on the roof surface. A solenoid-controlled valve controls the supply of water to the system over periods during which the temperature of the roof surface is measured to be within a predetermined temperature range. A thermistor, encapsulated in an expoxy block, is affixed to the roof surface and monitors and measures the actual roof temperature.

Abstract: A portable cooling and refreshment shower assembly including dismantlable pipe sections supporting and interconnected with a showerhead structure at its upper end and supported in its vertical orientation by radially extending base pipe sections. The base pipe sections are dismantlable from the pipe sections supporting the showerhead. A water supply connection is provided the shower assembly and water fills the base pipe sections to provide ballast to the shower structure during operation of the shower.
