Abstract
A device and method for the production of artificial snow. The device comprises an environment wherein temperature, humidity, and/or other environmental conditions are adapted to be controlled. The device also has at least one snow gun having at least the nozzle portion thereof provided substantially within or adjacent to the environment. Within the environment, the humidity and temperature may be controlled by a dehumidifier and a cooler or chiller, such that the environmental conditions are satisfactory for snow production. Alternatively, the controlled environment may be provided wherein the nozzle or the environment adjacent the nozzle is controlled to be of desired temperature and humidity.
Claims10
A device for the production of snow adjacent the downstream end of the device, comprising:
- (A) a first outlet to supply water therethrough under pressure;
- and
- (B) a second outlet to supply cryogenic gas therethrough provided substantially adjacent to or downstream in said device from said first outlet;
- whereby, as water is emitted from said first outlet and subsequently passes through the cryogenic gas, the temperature of the water is lowered to form snow adjacent the downstream end of said device;
- said device being characterized by causing the formation of the snow in the absence of propeller means.
A device for the production of snow adjacent the downstream end of the device, comprising:
- (A) a first outlet to supply water therethrough under pressure;
- and
- (B) a second outlet to supply cryogenic gas therethrough said second outlet being provided substantially adjacent to or downstream in said device from said first outlet;
- whereby, as water is emitted from said first outlet and subsequently passes through the cryogenic gas, the temperature of the passing water is lowered to form snow adjacent the downstream end of said device;
- said device being characterized by causing the formation of the snow in the absence of propeller means.
A device for the production of snow adjacent the downstream end of the device, comprising:
- (A) a first outlet to supply water therethrough under pressure;
- (B) a second outlet to supply cryogenic gas;
- (C) a third outlet to supply a gaseous substance therethrough under pressure;
- wherein, each of said first and third outlets are provided substantially adjacent to or upstream from said second outlet such that the products emitted from said first, second and third outlets substantially mix downstream from said first and third outlets in said device, whereat the temperature of the water is lowered such that snow is formed adjacent the downstream end of said device.
A method for the production of snow adjacent the downstream end of a device, comprising the steps of:
- (A) supplying water under pressure to an inlet of a nozzle of the device;
- (B) maintaining an artificial by supplying environment cryogenic gas adjacent to a downstream in the device form an outlet of the nozzle;
- and
- (C) causing the water to travel through the artificial environment;
- whereby, as the water travels through the artificial environment, the water is lowered in temperature such that snow is emitted from the artificial environment adjacent the downstream end of the device;
- no propeller means being required to cause the formation of the snow.
