Summary

THE AUTHORS NOTE THAT THE KEY TO INCREASING EFFECTIVENESS OF AIR COOLING IS IMPROVING AIR DISTRIBUTION. A MODEL WAS SET UP TO RESEARCH THE EFFECT OF DIFFERENT METHODS OF AIR DISTRIBUTION ON COOLING TIME OF STACKS OF CONTAINERS OF POTATOES. ELEVEN DIFFERENT METHODS WERE TRIED AND EVALUATED FOR TEMPERATURE AND AERODYNAMIC PARAMETERS DURING SUDDEN TEMPERATURE CHANGES. TWO FORMULAS WERE USED: ONE FOR DETERMINING EFFECTIVENESS EXPRESSED AS A PERCENTAGE, THE OTHER FOR DETERMINING THE AVERAGE COOLING TIME AT THE CENTER OF THE CONTAINER. THE AUTHORS ALSO GIVE GENERAL RECOMMENDATIONS: 1) CHILLED AIR SHOULD BE MADE TO GO IN AN UPWARD DIRECTION ; 2) EFFECTIVENESS CAN BE INCREASED BY CHANELLING AIR INTO A DEAD-END, WHICH ALLOWS A ZONE OF INCREASED PRESSURE TO BE CREATED ON THE SURFACE OF THE STACKS ; 3) EFFECTIVENESS CAN ALSO BE RAISED BY INCREASING THE AREA OF INTERACTION BETWEEN INFLOW AIR AND THE SURFACE OF THE STACKS.
