JPH05113278A - Artificial snow production - Google Patents

Abstract

PURPOSE:To obtain an artificial snow production method by which artificial snow used for skiing can be produced at any time. CONSTITUTION:A refrigerating mat 1 is laid over a ground surface to shield the heat of the earth and covered with a sheet so as to form a room 3. The air zone in the room 3 is forcibly cooled to -3 deg.C or lower by an adequate refrigerating machine and atomized water is sprayed into the cooled air zone and sublimated to produce snow.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an artificial snowmaking method for artificially making snow used when skiing.

[0002]

2. Description of the Related Art Conventionally, a snowfall machine used in a ski resort waits until the temperature of the outside air falls below -3 ° C. and injects water to make snow.

[0003]

In the snow making by the above-mentioned conventional method, it can be operated for the first time under the condition of the outside air. In the case of warm winter, even if the artificial snowfall system is introduced, it cannot be operated. There was a case that the purpose of could not be achieved.

[0004]

SUMMARY OF THE INVENTION In view of the above-mentioned circumstances, the present invention addresses this problem by providing a frozen mat on the surface of the ground at any time, rather than waiting for outside air to fall below -3 ° C. Laying the sheet, etc. on the frozen mat to forcibly cool the internal air layer constructed in a dome shape with a sheet or the like to -3 ° C or less, and spraying water into the air layer to spray this water. It provides a method of sublimation to make snow.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows an embodiment of an apparatus for an artificial snow making method according to the present invention, which will be described with reference to this drawing.

[0006] Reference numeral 1 denotes a freezing mat laid flat on the ground surface with a canvas or the like to prevent geothermal heat. The freezing mat 1 is covered with a sheet 2 of canvas or the like to be constructed in a dome shape, and the built-in chamber 3 The inside air layer is forcibly cooled to -3 ° C or lower by an appropriate refrigerating means (not shown) connected to the inside of the chamber 3, and the nozzle 4 is used to store water in the cooled air layer. Water is sprayed to sublime the water to make snow.

[0007]

As described above, according to the artificial snowmaking method of the present invention, in the conventional snowfall machine, the condition of outside air is -3 ° C.
Although snow could not be produced unless the temperature was below the range, the present invention makes it possible to easily produce snow even at a temperature of -3 ° C or higher, and the effect is remarkable.
