REFRIGERATOR FOR CONTAINER

摘要

Cooling operation is performed so as to keep a freezer at a selected temperature. Moreover, if the cooling operation enters a phase where the freezer temperature is higher than the selected temperature by a predetermined deviation or more, not only the deviation temperature but also an accumulated time obtained by accumulating the time periods during which the cooling operation is performed at the deviation temperature or higher are stored. In addition, when an instruction signal to indicate an accumulation is input, the stored accumulated time and deviation temperature are read out and indicated on a segment indicating section (7S). <IMAGE>
