ている。A humidifier 15 is connected to the lower end of the inner cylinder 12 through a discharge pipe 16, and this humidifier 15 supplies water vapor into the inner cylinder 12 to create artificial snow as described above. The air suction pipe 17 of the humidifier 15 is connected to the side surface of the cooling tower 4 so as to suck the cold air inside the cooling tower 4. A bypass pipe 18 is connected to the air suction pipe 17, and air outside the cooling tower 4 is supplied to the humidifier 15 through this bypass pipe 18. A flow rate control valve 20 is installed in the bypass pipe 17, so that the amount of inflow of external air can be adjusted.

になっている。Slightly above the discharge port of the discharge pipe 16 of the humidifier 15,
Nozzles 2 and 1 are provided, and this nozzle 21 is connected to the pipe 2.
A second cooling device 24 is provided in the middle of this pipe 22 to cool the compressed air from the air compressor 23.
雪を作るに先立って、まず、第１冷ｆＡ装＠９を作動さ
せて冷却塔４内の空気を冷却する。同時に、ブロワ１４
を作動させて内筒１２内の空気を循環させる。こうして
、内筒１２内の空気が第１冷却装置９によって間接的に
冷却される。内筒１２内の空気温度が、たとえば約−１
５℃になって安定するまでこの冷却操作を続ける。普通
、この温度の範囲は一１５℃〜−１０℃である。Prior to making snow, first, the first cold fA unit @9 is operated to cool the air in the cooling tower 4. At the same time, blower 14
is operated to circulate the air inside the inner cylinder 12. In this way, the air within the inner cylinder 12 is indirectly cooled by the first cooling device 9. The air temperature inside the inner cylinder 12 is, for example, about -1
This cooling operation is continued until the temperature reaches 5°C and stabilizes. Typically, this temperature range is between -15°C and -10°C.
内筒１２内の温度が安定したならば、ブロワ１４の回転
数を下げ、内筒１２内の風速を低下、たとえば、０．５
１１１／Ｓに低下させる。ここで、加湿器１５を作−動

まれた水蒸気は雲となる。この雲はブロワ１４の作動に
よって上昇する空気の動きにのって内筒１２内を上方に
移動し、過冷却雲となる。When the temperature inside the inner cylinder 12 becomes stable, the rotation speed of the blower 14 is lowered to reduce the wind speed inside the inner cylinder 12, for example, by 0.5.
Reduced to 111/S. Here, the humidifier 15 is activated to send mist water vapor into the inner cylinder 12. At this time, since the suction air is cooling air in the cooling tower 4, this water vapor is at a low temperature, for example, 0°C. Note that the temperature of the intake air can be adjusted by adjusting the intake amount of outside air by adjusting the control valve 20 of the bypass pipe 18 and mixing it with the cooling air from the cooling tower 4. The water vapor sent into the inner cylinder 12 becomes a cloud. This cloud moves upward within the inner cylinder 12 along with the movement of the air rising due to the operation of the blower 14, and becomes a supercooled cloud.
次に、エアコンプレッサ２３を作動させ、たとえば、約

、ここで自然現象と同様の現象が生じ、雲の中で雪が生
じ、それが成長して落下してくる。Next, the air compressor 23 is operated to send, for example, about 8 km of compressed air into the inner cylinder 12 through the nozzle 21. This compressed air is cooled by the second cooling device 24 on the way. The cooled compressed air flowing out from the nozzle 21 loses heat due to adiabatic expansion and is cooled to approximately -40°C, and the water contained therein becomes crystal grains, and these crystal grains are absorbed by the rising air in the inner cylinder 12. carried upwards. When the crystal grains touch the clouds present in the upper part of the inner cylinder 12, a phenomenon similar to a natural phenomenon occurs, and snow is formed in the clouds, which grows and falls.
ここで、ブロワ１４の回転を上げ、成長した雪が落下し
ないように内筒１２内上部に支えると、雪はさらに成長
する。ここで、ブロワ１４の回転を下げると、成長した
雪が連続的に舞い降り、開口部３を通って降雪至１に降
ることになる。Here, if the rotation of the blower 14 is increased and the grown snow is supported in the upper part of the inner cylinder 12 to prevent it from falling, the snow will grow further. Here, when the rotation of the blower 14 is lowered, the grown snow falls continuously and passes through the opening 3 until the snowfall reaches 1.

えることができる。In this way, the temperature inside the inner cylinder 12, the temperature of the cloud, the temperature of the crystal,
By controlling the speed of the upward airflow in the inner cylinder 12 by operating the blower 14 and the first cooling device 9.23, the size of the snow, the condition of the snow (wet snow, dry snow, etc.), the shape of the snow, etc. can be controlled. It can be changed.
