Apparatus for producing directed cold gas stream, e.g. for artificial snow production, comprises compressor for supplied gas, cooler for abstracting heat of compression and nozzle arrangement

摘要

Apparatus for producing a cold gas stream comprises a compressor (4) for supplied gas, with a cooler (5) for abstracting the heat of compression of the gas and a nozzle arrangement (9) for producing a directed gas stream. An independent claim is included for a corresponding method for producing a cold gas stream, in which a gas is compressed, cooled and expanded in a nozzle arrangement to create a directed gas stream.
