Abstract
PURPOSE: To provide a diagnosing apparatus capable of judging the operational conditions of a compressor correctly and promptly.
CONSTITUTION: In order to bring a judgement from a polytropic index, a quantitative relationship between a polytropic index and a trouble is stored beforehand in a memory 19a. In a comparator 18, an actual polytropic index nR, obtained by calculating the result of measurement by pressure detector 11, 13 disposed respectively on the upstream side and downstream side of a compressor by a calculator 17 by use of a predetermined equation, is compared with stored values n1Wn4 or n1'W n4' for judging the stage of trouble. Further, in order to obtain judgement from the outlet cempera ture, a quantitative relationship between the trouble and the reviation between the theoretical outlet temperature and the actual outlet cemperature is stored beforehand in a memory 19b. In the compa rator 18, comparison is made between the values obtained by calculating the result of measurement by temperature detectors 12, 14 and values ΔT1WΔT3, ΔT1'WT3' stored in the memory for judging the state of trouble.
