Definitions

  • Low-pressure snow cannons are probably the most used in snow production for ski slope snowmaking today. They consist of a tube in which an axial fan is located on the inlet side, and on the outlet side the water nozzles, which spray on the conveyed air jet. The cold ambient air makes the fine water droplets freeze to snow crystals, which then fall to the ground as snow.
  • the invention consists in that on the outlet side of the snow gun, a diffuser is mounted, which surrounds the emerging from the snow gun water-air mixture with a cold air jacket. By this diffuser more air is conveyed, and it can be sprayed at the same energy more water in the air jet, resulting in a higher snow performance and more efficiency in snow production.
  • the Fig. 2 shows a low pressure snow gun according to the invention consisting of a snow pipe 1, an axial fan 2, which is mounted in the inlet region of the snow pipe 1, a nozzle ring 3, and Nucleusdüsen 10, wherein after the nozzle ring 3, a first diffuser 4 with a, spaced from the snow pipe 1, funnel-shaped extension is arranged. Furthermore, an adjusting device 5 for the snow gun, and a supply line 11 for a water-air mixture to the Nukelusdüsen 10 is provided.
  • a second diffuser 9 is provided, which is arranged in front of the nozzle ring 3 in the air flow direction, and the nucleus nozzles 10 are arranged in the air flow direction in front of the second diffuser 9.
  • the invention thus consists in that the second cutting diffuser 9 draws a coat of dry air 7 over the air stream 6 moistened by the nucleus nozzles 10, so that the water sprayed via the nucleus nozzles 10 does not freeze on the wall of the snow pipe 1 (see FIG Fig. 2 ).
  • the following nozzle ring 3 with the water nozzles remains.
  • the diameter of the first diffuser 4 at its narrowest point at the inlet, and the diameter of the first diffuser 4 at the outlet may be adjustable. Furthermore, the first diffuser 4 can be adjustable in the axial direction, as well as in the radial direction to the main axis of the snow pipe 1.
