To provide a cooling compressor control device that can properly control the interior temperatures of both a refrigerating room and a freezing room, with respect to a single cooling type refrigerator-freezer.

In a control device 19, if the interior temperatures of both a freezing room 110 and a refrigerating room 120 become high, the number of revolutions of a compressor motor is set to be high. Therefore, cooling is quickly performed in the freezing room 110 and refrigerating room 120, so that the excellent storage state of a stored object is kept in the freezing room and the freshness of a stored object is kept in the refrigerating room.
