Description

Indoor ski structure {INDOOR SKI STRUCTURE}

According to the indoor ski structure disclosed in the Japanese Patent Laid-Open, an air cooling device blows cold air of about -5 to 15 ° C into the inside of a building and simultaneously supplies compressed air and water from an air compressor and a water supply device and sprays the spray nozzles. As a result, the particulate water is made into artificial snow and accumulated on the slopes. In order to maintain the condition of the snow of this slope well, it cools to around -5 to -10 degreeC by supplying cold air to the inside of a building.

In order to build snow on these buildings and accumulate on the slopes, the entire interior of the building must be cooled. An air cooling device for supplying cold air into a building requires a very large capacity, and there is a problem in that an energy cost increases due to the enlargement of the device.

Accordingly, it is an object of the present invention to provide an indoor skiing structure capable of keeping the temperature inside the indoor skiing structure low in an efficient manner.
