Abstract

As a means of exporting agricultural produces, air transport is mainly adopted to keep them fresh in Japan. On the other hand, marine transportation has been focused to reduce freight costs recently. Although it is necessary to consolidate various kinds of fresh produces to fill a container, fruit and vegetables have each suitable storage temperature. Here, we attempted to develop the dual temperature reefer container, which includes two rooms set at 0℃and 10℃ individually, and considered the design guideline by using CFD (Computational Fluid Dynamics). The validity of the prediction model was verified by comparing the measured temperature and predicted temperature and then temperature distribution and velocity distribution of the air in the container was visualized under the outside air temperature of 38℃ and 0℃ and various conditions. As a result, we could obtain basic guidelines to design the dual temperature storage container.
