Method and apparatus to prevent snow melting and to keep snow in artificial ski facility

摘要

A method for preventing snow melting and packing snow in an artificial skiing facility by injecting dry or cold air through the snow cover of the artificial skiing facility. The entire snow cover can be effectively cooled to prevent snow melting and to compact snow. If hot air is injected before the cold air is injected, the cold air is effectively spread and the formation of frozen snow is prevented by the injected hot air. In these methods, if dry air, cold air and hot air are injected from the bottom of the snow through a header having a plurality of air inlet outlets, snow melting can be prevented and snow packing You can achieve this more effectively. This header is preferably configured in a twisted or serpentine form or on a lattice on the platform of the ski facility.
