Gas refrigerating machine, method for operating a gas refrigerating machine and method for manufacturing a gas refrigerating machine as open system

Abstract

A gas refrigerating machine comprising: an input (2) for gas; a recuperator (10); a compressor (40) having a compressor input (41), the compressor input (41) being coupled to a first recuperator output (12); a heat exchanger (60); a turbine (70); and a gas output (5), wherein the gas refrigerating machine is configured as open system, and wherein the gas refrigerating machine is configured such that a working medium in at least one element of the group of elements comprising the recuperator (10), the compressor (40), the heat exchanger (60) and the turbine (70), is the gas, and wherein the input (2) is arranged at a first portion of a housing (100) of the gas refrigerating machine where the input (2) and the gas output (5) are configured, wherein the gas output (5) is arranged at a second portion of the housing (100) of the gas refrigerating machine, and wherein the first portion is arranged above the second portion in an operating direction in which the gas refrigerating machine is set up for an operation of the gas refrigerating machine.
