S P E C I F I C A T I O N METHOD OF CREATING AN OUTDOOR ICE SLAB IN SUMMER WEATHER AND OF REDUCING ENERGY REQUIREMENTS FOR INDOOR AND OUTDOOR ICE RINKS ABSTRACT Heretofore it has been completely impractical to try to create and hold ice for the purposes of ice skating, curl- ing or sliding during summer weather unless the area were com- pletely enclosed. This invention presents a method for doing this which is practical not only by keeping refrigeration re- quirements low but also by eliminating dripping, fogging and surface melting. This method also has the advantage of reduc- ing energy requirements for holding an ice slab under indoor or outdoor conditions. The method includes creating a floor for ice under which tubes or pipes containing an antifreeze so- lution are laid, connecting a refrigeration plant to chill and recirculate the antifreeze solution, suspending a surface of aluminum foil facing downward covering the entire ice floor at least ten feet above such floor, mounting fans to recirculate the air from below such aluminum surface to above it, freezing ice by applying water upon the floor, painting the ice white to reflect radiant energy, freezing more ice above the white paint, erecting a solid perimeter fence around the ice floor, blowing air through a header box alongside the rink to de- humidify the air and delivering that air through openings in the perimeter fence onto the ice floor area and certain com- binations of the above steps. The low emissivity of the aluminum foil and the high reflectivity of the white paint prevent radiant energy from loading the ice while recircu- lation fans warm the cool moisture laden and often foggy air over the ice by conveying it to the warm area above the sus- pended ceiling. - 1 -
