1. A gas refrigerating machine comprising:
an input for gas;
a recuperator;
a compressor comprising a compressor input, the compressor input being coupled to a first recuperator output;
a heat exchanger;
a turbine; and
a gas output,
wherein the gas refrigerating machine is formed as an 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, the compressor, the heat exchanger and the turbine, is the gas, and
wherein the input is arranged at a first portion of a housing of the gas refrigerating machine where the input and the gas output are configured, wherein the gas output is arranged at a second portion of the housing 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.
