Gas refrigerating machine, method for operating a gas refrigerating machine and method for manufacturing a gas refrigerating machine having a rotationally symmetrical design

A method for operating a gas refrigerating machine comprising:

• an input for gas to be cooled;
• a recuperator comprising a first recuperator input, a first recuperator output, a second recuperator input, and a second recuperator output;
• a compressor comprising a compressor input and a compressor output, the compressor input coupled to a first recuperator output;
• a heat exchanger comprising a first heat exchanger input and a first heat exchanger output on a primary side of the heat exchanger, and a second heat exchanger input and a second heat exchanger output on a secondary side of the heat exchanger;
• and a turbine, the method comprising:
• feeding gas from the gas inlet into the first recuperator input;
• feeding gas in the first recuperator output into the compressor input;
