ABNORMALITY ALARMING DEVICE FOR TEMPERATURE CONTROL DEVICE

摘要

PURPOSE:To provide a temperature control device abnormality alarming device capable of predicting and alarming the generation of future abnormality without requiring a storage device having large capacity. CONSTITUTION:A microcomputer 3 controls the operation of a compressor 7 between the upper limit temperature and lower limit temperature of discharged air temperature based upon an output from a temperature sensor 4. A storage means successively stores the maximum and minimum values of the discharged air temperature inputted from the microcomputer 3 and data relating to time or a period generating the values. An abnormality judging means judges and alarms the fine temperature abnormality and operation rate abnormality of a temperature control device 1 based upon the data stored in the storage means.
