<P>PROBLEM TO BE SOLVED: To execute a cooling operation while more preferably protecting devices as a back-up operation even in a failure of a discharge gas temperature sensor. <P>SOLUTION: In this refrigerating device 10, a control device 9 controls a compressor 18 in a direction to lower a discharge gas temperature DT when the discharge gas temperature DT rises to a prescribed value or higher on the basis of the discharge gas temperature DT detected by the discharge gas temperature sensor 52, and determines an operational frequency of the compressor 18 to a specific low value to assume that the discharge gas temperature DT does not rise when an outside air temperature AT detected by an outside air temperature sensor 48 is higher than a prescribed outside air temperature AT1 when the discharge gas temperature sensor 52 is abnormal. <P>COPYRIGHT: (C)2012,JPO&INPIT |
