There are two types: the so-called gun type and the fan type. The gun type is known in Japanese Patent Publication No. 42-26918, and the fan type is known in Japanese Patent Publication No. 49-46343. A gun-type artificial snow-making device (snow-making gun) mixes water and compressed air and sprays the mixture at high speed. Compressed air released into the atmosphere expands adiabatically and absorbs heat from its surroundings, thereby cooling the water particles. Furthermore, the cooled water particles are blown a suitable distance by the jet of compressed air. Fan-type artificial snowmaking equipment uses an axial fan installed inside a wind tunnel to draw in cold air from the air intake port of the wind tunnel to generate an air flow, which is then directed to water from multiple nozzles installed at the wind tunnel outlet. It injects compressed air. Water particles injected from the nozzle exchange heat with cold air before falling to the ground, becoming frozen ice crystals.

提供することを目的とする。[Problems to be Solved by the Invention] However, in the gun-type artificial snow-making device described above, since the water particles are blown away by riding on the jet stream of compressed air, a large amount of fairly high-pressure compressed air is required, and when the compressed air is released, A very loud explosion-like noise is generated. For this reason, it also disturbs the sleep of residents living around the ski resort or guests staying at hotels. In addition, since a large amount of compressed air is required,
A large compressed air generator is required, which increases the size of the equipment and facilities. On the other hand, fan-type artificial snow-making devices have problems such as not producing snow unless the atmosphere is at a certain low temperature. SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an artificial snow-making method and an artificial snow-making device that have both the structures of gun-type and fan-type artificial snow-making devices and eliminate the drawbacks of each.

FIG. 1 is a sectional view of an artificial snow making device. The artificial snow making device 10 is installed, for example, in a self-propelled vehicle. The wind tunnel 12 is formed in a cylindrical shape, and the discharge port 12b is formed to have a smaller diameter than the suction port 12a. The wind tunnel 12 is located near the suction port 12a in the wind tunnel 12.
An axial fan 14 is supported coaxially with a support member 16. Near the outlet 12b in the wind tunnel 12, a snow-making gun 18 is suspended by a support member 20 toward the outlet 12b. A nozzle ring 22 is provided at the discharge port 12b within the wind tunnel 12. This nozzle ring 2
2, a first nozzle 24 that sprays water particles in the form of a mist, and a second nozzle 26 that is a two-fluid nozzle that sprays a mixture of compressed air and water are arranged in concentric circles so that they are sprayed toward the air flow. There are multiple locations.

The first nozzles 24 are connected to the water supply path 28, and the second nozzles 26 are connected to the air supply path 30. Note that the second nozzle 26 has an orifice 3.

をさらに成長させる。Next, the operation of the above-mentioned artificial snow making device will be explained. It drives the axial fan 14 and supplies water and compressed air through the water supply pipe 34 and the air supply pipe 36. Then, the snow-making gun 18 injects a mixture of water and compressed air, and the compressed air released into the atmosphere adiabatically expands and absorbs heat from the surroundings, cooling the water particles. The cooled water particles are then blown far away by the air flow of the axial fan 14 along with the jet of compressed air, and even before they fall to the ground, they further exchange heat with the cold air and freeze. It can be made into ice crystals. Further, water particles are sprayed toward the air stream from the first nozzles 24, and a mixture of water particles and compressed air is sprayed from the second nozzles 26. Then, the water particles ejected from the second nozzles 26 form nuclei due to adiabatic expansion of the compressed air, and the water particles ejected from the first nozzles 24 fall to the ground on the airflow. During this time, the ice exchanges heat with the cold air, allowing the nuclei to grow and become frozen ice crystals. On the other hand, some of the water particles ejected from the first nozzles 24 cause the ice crystals formed by being ejected from the snow-making gun 18 to grow further.

多くの改変を施し得ることはもちろんである。[0010] The water and compressed air injected from the snow-making gun 18 are enveloped in the air flow of the axial fan 14, so that the noise generated from the snow-making gun 18 can be suppressed. In addition, when the snowmaking gun 18 releases compressed air, the compressed air expands adiabatically, so the temperature of the airflow decreases,
It is now possible to make snow in temperature ranges where conventional fan-type artificial snowmaking equipment could not make snow. Furthermore, axial fan 1
Due to the effect of the air flow in step 4, the water and compressed air ejected from the snow-making gun 18 can be prevented from flying far, so the amount of compressed air may be small. In the above embodiment, the wind tunnel 1
An axial fan 14 and a snowmaking gun 18 are installed in the wind tunnel 12.
The first nozzle 24 and the second nozzle 26 may not be provided in the inner discharge port 12b. In this case as well, snowmaking gun 1
The water and compressed air injected from the snow-making gun 18 are enveloped in the air flow of the axial fan 14, and the noise generated from the snow-making gun 18 can be suppressed. Although the present invention has been variously explained above with reference to preferred embodiments, the present invention is not limited to the above embodiments, and it goes without saying that many modifications can be made without departing from the spirit of the invention. .

It can have a soundproofing effect. Therefore, it does not disturb the sleep of residents near the ski resort or guests staying at hotels. ■ Also, the action of the snow-making gun can lower the temperature of the airflow generated by the axial fan.
It is now possible to make snow in temperature ranges where conventional fan-type artificial snowmaking equipment cannot make snow. Furthermore, by using a fan-type snow-making mechanism in combination, even more efficient snow-making becomes possible. ■ Compared to the case of snow making using only the conventional snow making gun, by using both types of snow making methods, that is, by using the air flow of the axial fan, the water sprayed from the snow making gun and the Not only can the compressed air be sent over long distances, but also by increasing the efficiency of heat exchange with the cold atmosphere, the amount of compressed air that is injected from the snowmaking gun can be reduced, and the compressed air generator can be downsized. It is.
