Abstract
The cold box is used for a delivery of perishable foods from a food center to a food store. This box has no ability to cool the food. Therefore, the large size refrigerator is used in the food center and food stores for the quality control of perishable foods. If the cold roll-box has the performance of the refrigerator with simple structure, the cold storage system of the food center and of food store become more simple. In this study, the cold roll-box with resin tube-mat as a heat transfer unit which has a role as ice energy storage vessel is manufactured and its thermal performance are verified experimentally and by employing a numerical calculation. As a result, it was found that this type cold roll-box has good performance as a cold box by employing the ice storage pack or the storage cell even small size.
