PROBLEM TO BE SOLVED: To provide a cold heat device capable of easily performing a reactivation operation after power source recovery, with a simple structure.SOLUTION: A cold heat device 40 has a cold heat unit 21 performing cold heat storage to a cold heat storage material 22 by a cold heat medium; connects a cold heat pipeline L2b, in which the cold heat medium fluidizes, to a conveyance box 1 holding a cold heat insulation space 23, in which a cold heat insulation object is stored by the cold heat storage material 22 subjected to cold heat storage, in a desired temperature range; and makes the cold heat medium inflow to the cold heat unit 21 through the cold heat pipeline L2b to perform cold heat storage to the cold heat storage material 22. The cold heat device includes: operation mode switches 44a, 44b setting an operation mode of the cold heat device 40, and mechanically holding a set operation mode state; and a control unit C that detects the operation mode state held by the operation mode switches 44a, 44b in initial operation start of the cold heat device 40, and performs control to execute processing of the detected operation mode.SELECTED DRAWING: Figure 2 |
