MECHANICAL REFRIGERATION USING AN EJECTOR-INJECTOR TO TRANSFER THE WORKING FLUID FROM THE EVAPORATOR TO THE CONDENSER.

Author(s) : BEVILACQUA P.

Type of article: Article, IJR article

Summary

THE REFRIGERATION PLANT DESCRIBED IN THE PAPER USES AN EJECTOR-INJECTOR INSTEAD OF A COMPRESSOR TO PUMP THE MIXTURE FROM THE EVAPORATOR TO THE CONDENSER. A PUMP DRAWS THE LIQUID FROM THE CONDENSER AND PUMPS IT TO ANOTHER VESSEL. BEFORE THE EJECTOR-INJECTOR, A HEAT EXCHANGER PREHEATS THE REFRIGERATING FLUID TO SPEED UP THE MIXING WITH STEAM EJECTED FROM THE EVAPORATOR. THE STEAM IS COMPRESSED USING KINETIC ENERGY IN THE EJECTOR-INJECTOR AND THE PUMP SUPPLIES A DISCHARGE PRESSURE TO OPERATE THE PLANT. THE HEAT TRANSFER FLUID, THE CONDENSING AND EVAPORATING PRESSURES AND THE ENERGY LOSSES DETERMINE THE OPERATING FEATURES OF THE PLANT. ENERGY SAVING IS OBTAINED USING SUCH AN EJECTOR-INJECTOR AND IT PROVIDES A SIMPLE METHOD OF REFRIGERATION. THE OPERATING CONDITIONS WERE OPTIMIZED AND THE FEASIBILITY OF THE PLANT WAS CONFIRMED.
