STEAM-EJECTOR REFRIGERATING MACHINE Russian patent published in 2000 - IPC

FIELD: refrigerating engineering. SUBSTANCE: heat formed at combustion of fuel in steam generator furnace is conveyed to water which evaporates generating the steam. Steam from steam generator gets into ejector through steam superheater, sucking out cold steams from refrigerator, and then mixture of hot and cold steams passes through condenser into steam-water pump-heater. Mixture of hot and cold steams passing through condenser gets condensed owing to heat exchange with cooling system. Hot steam gets through regulating valve into steam-water pump- heater simultaneously with condensate. Intensive mixing of steam and water takes place in steam-water pump-heater with provision of heater condensate of high temperature and pressure, owing to which condensate is delivered into steam generator. Under action of vacuum, condensate, after condenser, in sucked, through throttling valve, into refrigerator where it is partially evaporated in vacuum. The rest of condensate is cooled. This part of condensate circulates along closed cold water circuit 15, passing through cold consumers 17. EFFECT: increased cooling capacity of machine owing to reduction of energy consumption and mass and dimensions of machine. 1 dwg
