A snow making apparatus includes: a snow making container having an inner space for snow making; a supply unit configured to supply fine snow or fine water droplets to the inner space; a catching unit configured to catch the fine snow or the fine snow formed of the water droplets; and a drive unit configured to move the catching unit toward a place where the fine snow is flying in the inner space. The catching unit is configured to be shaken thereby making snow caught by the catching unit fall off from the catching unit.

The present invention relates to an artificial snow-making facility (1) comprising—a snow-making device (2),—a fluidic water pipe (3) for supplying water to said snow-making device (2),—potentially, a fluidic air pipe (4) for supplying air to said snow-making device (2),—control means (5) for managing the operation of said snow-making device (2),—a power supply for supplying electricity to said control means (5).

According to the invention, said power supply comprises a power generator (6) arranged on one of said fluidic pipes (4),

said power generator (6) comprising a turbine (61) adapted to be driven by the fluid of said fluidic pipe (4).

A refrigeration plant including: a first enclosure containing water in the liquid state at a temperature lower than or equal to the temperature of the triple point of water or higher than the temperature of the triple point of water by less than 10° C., and water in the gaseous state at a first pressure equal to the saturated vapor pressure of the water in equilibrium with the pressure of the water in the liquid state; a second enclosure at a second pressure strictly higher than the first pressure by a factor of at least two; a compression device connecting the first enclosure to the second enclosure; a condensing device adapted to condense the water in the gaseous state in the second enclosure into water in the liquid state; and a cold power extraction device for extracting cold power in the first enclosure.

Disclosed is a snow making method incorporating nucleation agent particles into water and in spraying the water containing the nucleation agent particles onto a surface or into an ambiance whose temperature is lower than 0° C., by way of a device for producing snow or ice. The nucleation agent particles consist in silicate particles whose unit equivalent spherical diameter is lower than 15 μm, and preferably lower than 5 μm. Also disclosed is the powdery product for implementing the method.

A snow making apparatus includes a cylindrical body and a snow making nozzle that jets water droplets into the cylindrical body. The cylindrical body has a proximal end that is opened to a temperature environment where snow can be produced from water droplets jetted from the snow making nozzle. A distal end of the cylindrical body is connected to a pipe member communicating with a test chamber. The snow making nozzle is formed of a two-fluid nozzle. The pipe member communicates with a snowfall hood disposed in the test chamber and having a supply opening that allows snow to fall. The cylindrical body is disposed in an oblique posture so as to be lowered from a proximal end toward a distal end of the cylindrical body.

The Situational Atmospheric Vectoring Equipment (abbreviated in this document as equipment) provides a system to disperse an aqueous liquid in a solid or gaseous form. In accordance with an embodiment of the invention, the equipment comprises: a pressure vessel or external source for the aqueous liquid, a mechanical pump if required, a pressure vessel for the cryogen, mechanical lines connecting the aqueous liquid and cryogen allowing for flow control, a nozzle for fluid acceleration and, optionally, a mechanical fan for dispersal. Previous inventions of this category require the proper environmental conditions are present whereas the equipment, as described in this text, does not have this limitation.

A method, in particular for generating snow from water, using a low-pressure hydraulic device having a pump unit, to which a purification system is connected, and a distribution device having at least one high-pressure pump, to which a high-pressure unit having a snow cannon and/or a different snow-generating unit is connected. In order for the bonding of the water molecules in the supermolecular water structure of the process water to change and the generation of snow to improve, according to the invention at least part of the water used is exposed to an ionization field and/or a polarization field while simultaneously being exposed to the effects of an alternating electromagnetic field so that a weaker bonding of the water molecules in the supermolecular water structure is achieved, resulting in an improvement in the absorption and transfer of heat. The invention further relates to a device for carrying out the method.
