Summary

AIR CURTAINS ARE FREQUENTLY FITTED TO THE DOORWAYS OF COLD STORE ROOMS OR FREEZING CHAMBERS. THE AUTHORS FOUND THAT JET FLOW WITH A NARROW OPENING DOES NOT EFFECTIVELY ISOLATE INSIDE AIR FROM THE EXTERNAL ATMOSPHERE, BUT A RELATIVELY WIDE OPENING DECREASES AIR ENTRAINED FROM THE SURROUNDINGS. SINCE VARIOUS CONDITIONS CAN BE EASILY CHANGED BY NUMERICAL CALCULATION, THE AUTHORS COMPARED THE VELOCITY AND TEMPERATURE FIELD IN A COLD ROOM UNDER CONDITIONS WHEN THE VELOCITY OF JET FLOW IS CHANGED BY NUMERICAL METHODS. FROM THESE RESULTS, IT WAS DEDUCED THAT AN AIR SHUTTER IS MORE EFFICIENT THAN AN AIR CURTAIN.
