SNOW MAINTENANCE CONTROL METHOD FOR INDOOR SKI SLOPE AND ITS DEVICE

摘要

PROBLEM TO BE SOLVED: To constantly and favorably maintain snow quality and to restrain energy consumption by improving its control precision in a snow maintenance control method of an indoor type ski slope. ;SOLUTION: Artificial snow 16 of a slope 17 is melted from a lower surface part, and the artificial snow 16 is replenished by spraying it on an upper surface part. Additionally, thickness is constantly maintained constant by supplying cold air to an upper space of this artificial snow 16, and heat balance is held to be a constant value by making ceiling and wall radiant heat, skidding load heat, lighting heat input, slope underfloor invading heat, snow surface cooling heat and evaporation latent heat as control elements and controlling the snow surface cooling heat by adjusting temperature of cooling air supplied to an upper space of the slope 17 so that heat balance is held constant value.;COPYRIGHT: (C)1999,JPO
