Abstract (en)
The system (1) has a water jet-gas compressor (2) in which water (W1) is introduced as driving medium in the form of propulsion jet under pressure in a suction chamber. Air (L1) is sucked into the water jet-gas compressor over an air suction opening. A separation arrangement (3) separates water-air-mixture (M) from the water jet-gas compressor, and a snow device (4) i.e. snow cannon, produces artificial snow. The arrangement is connected with the snow device, such that water (W2) and air (L2) from the arrangement is separately supplied to the snow device. An independent claim is also included for a method for producing artificial snow.
Abstract (de)
Ein Beschneiungssystem enthält eine Einheit (10) mit einem Wasserstrahl-Gasverdichter (2), in den Wasser (W1) als Treibmedium unter Druck in eine Ansaugkammer (7) in Form eines Treibstrahls einleitbar ist und in den Luft (L1) ansaugbar ist. Die Einheit weist weiter eine Trennanordnung (3) zum Trennen des Wasser-Luft-Gemisches (M) aus dem Wasserstrahl-Gasverdichter in Form einer Trennkammer auf, wodurch Wasser (W2) und Luft (L2) aus der Trennanordnung separat einer Schneilanze (4) zum Erzeugen von künstlichem Schnee zuführbar sind.
