<P>PROBLEM TO BE SOLVED: To achieve an internal temperature control that is appropriate as a backup operation, by controlling a compressor based on the temperature of an evaporator detected by a defrost sensor, even when an internal temperature sensor is failed. <P>SOLUTION: In a refrigerating apparatus 10, a control device 9 controls the compressor 18 based on the temperature PT detected by the internal temperature sensor 31 in a normal state. When the internal temperature sensor 31 is abnormal, the temperature PT is substituted by a temperature obtained by adding a predetermined offset value OV to a temperature ET of the evaporator 11 detected by a defrost sensor 28, and by changing the offset value OV based on an external temperature AT, thus controlling the compressor 18. <P>COPYRIGHT: (C)2012,JPO&INPIT |
