Flywheel Cooling: A Cooling Solution for Non Air-Conditioned Buildings

"Flywheel Cooling" utillzes the natural cooling processes of evaroration, ventilation and air circulation. These systems are rroviding low-cost cooling for distribution centers, warehouses, and other non air-conditioned industrial assembly rlants with little or no internal 10iids. . The eva[lorative roof cooling system keers the building from heating U[l during the day by misting the roof surface with ii fine srray of water - just enough to evaporate. This process keeps the roof surfJce iit 90'Ievels inste;td of ISO' and knocks out the rildiant heat transfer from the roof into the building. The system is controlled by a thermostat and automatically shuts off at night or when the roof surface cools helow the set point. The same control system turns on exhaust fans to load the building with cool night air. Air circulators are installed to provide air movement on workers during the day. Best results are achieved by closing dock doors and minimizing hot air infiltration during the day. The typical application will maintain inside temperatures that wiU average 84' - 86' when outside ambient temperatures range from 98' - 100'. Many satisfied users will attest to marked improvements in employee moral and productivity, along with providing safe storage temperatures for many products. InstaUed "Flywheel" systems' costs are usuaUy less than 20% of comparable air-conditioning equipment. By keeping a built up roof cooler, the system will eliminate thermal shock and extend roof life while reducing maintenance.
