PURPOSE:To enhance the use-efficiency of racks by vertically partitioning racks from each other by means of heat insulation boards so that the higher a partition is located the higher the temperature is. CONSTITUTION:Heat insulation boards 8... are fixed to racks 2... in such a manner that the boards 8... separate the racks 2... into three areas, A1-A3, in the vertical direction and moreover they do not projection into a passage 3. The upper are A1 is heated by radiant heat from a roof 7 receiving sunshine, while the lower area A3 is cooled off by cool air flowing in 10 by a refrigerator 9. Thus, the upper area A1 is assigned to a heat insulation area for a temperature of 30 deg.C or higher, while the intermediate area A2 to a storage area for 20-30 deg.C, and the lower area A3 to a storage area 10-20 deg.C. With this constitution, racks can be used with high efficiency and the cargo distribution efficiency can also be enhanced. |
