摘要： A method and apparatus for the maintenance of snow quality on an indoor artificial ski slope. The snow quality of the slope, comprising a thin compacted surface layer and a deep unfused base layer, is maintained by promptly managing against the variations of snow quality due to various heat sources. The old surface layer snow is replaced with fresh snow on a daily basis, while deterioration of the snow base layer is prevented by air conditioning and refrigeration means. The old snow is melted, filtered, and used to make new snow, to air condition the slope, and to expedite melting of yet additional old snow.
