The development of an energy efficient and economical modified jacketed vegetable storageconcept and design is presented. Most fruits and vegetables require a storage environmentnear 0°C and 100% rh; which is difficult to achieve with conventional refrigeration systems.In a jacketed storage system, refrigerated air is circulated through air spaces surroundingthe storage. High relative humidity levels can be achieved through the use of the large heattransfer surface of walls, ceiling and floor maintained at uniform temperature, and bypreventing transmission heat gains into the storage space. While the jacket concept wasinitially introduced as a full jacket (covering walls, ceiling and floor), this paperdiscusses an alternative jacketed design which uses only the ceiling as a heat transfersurface. Based on construction simplicity, it is felt that this jacket design can be appliedto conversion of conventional storage facilities and to new storage facilities. Acceptablerelative humidity levels are attainable by the jacketed ceiling design with an extended heattransfer surface. It is expected that this concept will find favourable applications forstoring fruits and vegetables wherever high humidity, medium temperature cold rooms arerequired.
