The integrated controller 10 controls a defrosting operation to remove frost adhered to showcases 53, 54, and 55 . . . , in which the defrosting operation is started at a fixed or varying time interval. The integrated controller 10 stores past record data based on required time for past defrosting operations for different environmental conditions. The integrated controller 10 includes an environmental condition acquisition unit 141 for obtaining present environmental conditions; a database control unit 142 for obtaining required time for a present-round defrosting operation based on the past record data corresponding to the present environmental conditions from among the stored past record data; and a start time changing unit 143 for changing start time of the present-round defrosting operation based on the obtained required time from the scheduled start time.
