PROBLEM TO BE SOLVED: To allow an operation program and an intra-storage temperature history data to coexist while reducing the number of flash memories to be used and to prevent the operation program from being stopped even in the case of writing intra-storage temperature data in a flash memory. SOLUTION: In a refrigeration unit for a container, one flash memory 61 is stored in a control unit 50. An operation program and intra-storage temperature history data are stored in the memory 61. At the time of starting the refrigeration unit, the operation program in the memory 61 is copied to a RAM 62. At the time of operating the refrigeration unit, the program is read out from the RAM 62 to control operation and intra-storage temperature data are written in the memory 61. |
