FIELD: cryogenic engineering and cryogenic refrigerating machines operating on the Stirling reverse cycle principle, applicable for thermostatting of special stationary objects, as well as for transport facilities. SUBSTANCE: liquid nitrogen with the aid of an immersion pump is fed to an air-cooled panel positioned in a heat-insulated cooled volume. Liquid nitrogen cools down the volume to the necessary temperature and evaporates. The flow of nitrogen gas is expanded in the high- and low-pressure turbines producing a useful work and preheated in the heat exchanger. From the expansion vessel nitrogen is fed to the condenser of the Stirling cryogenic machine, where it gets liquefied and overflows to the Dewar flask, from which it is fed to a vessel by a high-pressure pump. Refrigerating liquid from the refrigerator heated from the working medium of the Stirling machine is fed to the heat exchangers for cooling by the environment and then by nitrogen. The Stirling refrigerating machine is driven by the electric motor of a special heat engine or engine of the transport facility. EFFECT: prevented irrevocable loss of expensive gas-nitrogen, use of the system for thermostatting of inhabited rooms without disturbance of the composition of air inside these rooms at a high level of explosion- and fireproofness, and generation of additional electric power. 1 dwg
