Abstract
PURPOSE: To permit diagnosis with constant high reliability by judging the operation state of a compressor and fault etc. of equipment in response to the variation of the state amounts such as temperature, pressure etc. by which the operation state of the compressor is influenced.
CONSTITUTION: The signals of the pressure detector 11 and the temperature detector 12 which are installed for diagnosis are entered at first, and the values of these state amounts are compared with the reference values prepared beforehand, and thus the degree of fault is diagnosed. According to the judgement results, indication of heavy fault, light fault, and normal, output of motor stop in case of heavy fault, and indication of the contents of fault are outputted. Change of the reference values is determined on the basis of the state amounts such as temperature etc. The reference values are prepared by means of the functions and concerns which shall be determined beforehand with a some allowance for the present values of the state amounts obtained by the signals of the detectors 11 and 12 installed for diagnosis.
