FIELD: refrigerating engineering. SUBSTANCE: working medium in form of compressed mixture of hydrocarbons (natural gas) featuring excessive pressure energy is delivered to expansion turbine connected with gas compressor. After turbine, two-phase flow is directed into separator wherefrom gas phase is delivered into compressor, and then into mixer. Liquid phase is delivered from separator into mixer by circulation pump through condensate flow regulator and cold consumer. Excess condensate is delivered into storage. EFFECT: reduced energy consumption, increased profitableness at production of cold. 1 dwg
