ABSTRACT:
Heretofore it has been completely impractical to try to create and hold ice for the purposes of ice skating, curling or sliding during summer weather unless the area were completely enclosed. This invention presents a method for doing this which is practical not only by keeping refrigeration requirements low but also by eliminating dripping, fogging and surface melting. This method also has the advantage of reducing 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 solution 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 10 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 dehumidify the air and delivering that air through openings in the perimeter fence onto the ice floor area and certain combinations 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 recirculation fans warm the cool moisture-laden and often foggy air over the ice by conveying it to the warm area above the suspended ceiling.
