STEAM-JET REFRIGERATING PLANT Russian patent published in 2001 - IPC

FIELD: refrigerating engineering; air- conditioning system for stationary and mobile objects. SUBSTANCE: steam from steam generator is fed to steam superheater through which combustion products of fuel are passed. While passing through ejectors steam makes cold steam be sucked from cooler, thus forming vacuum in its upper section. Steam mixture admitted to condenser is condensed due to heat exchange with cooling system. Condensate thus formed is admitted to steam-and-water pump-preheater where steam mixture from ejector is admitted simultaneously with condensate. Steam-and-condensate mixture is intensively mixed in steam-and-water pump-preheater, thus forming preheated condensate at high temperature and pressure. Preheated condensate is fed to steam generator due to pressure. Part condensate is fed to refrigerator through valve due to vacuum formed in upper portion of refrigerator where it is partially evaporated in vacuum and remaining part of condensate is cooled down. This part of condensate is circulated in closed cold water loop flowing via the cold consumer. EFFECT: increased refrigerating coefficient. 1 dwg
