FIELD: machine building. ^ SUBSTANCE: method of producing cold air in turbo-refrigerator comprises atmospheric air withdrawal, compressing aforesaid air in turbo-compressor compressor, cooling it feeding it to turbo-expander compressor inlet. It compresses compressing it additionally, cooling and feeding to turbo-expander turbine inlet, cold air being transferred from turbo-expander turbine outlet to its inlet. Compressed air flow coming from turbo-compressor compressor is divided into two flows. One flow is fed, via air cooler, to the turbo-expander compressor inlet. Second flow, preferably that with lower flow rate, is directed into combustion chamber to oxidise fuel, while resultant combustion products are mixed with steam. Steam is produced by power of gases outcoming from turbo-compressor turbine. Mix obtained is sent to turbo-compressor turbine. ^ EFFECT: increased refrigeration factor. ^ 1 dwg |
