摘要： PROBLEM TO BE SOLVED: To perform an early sensing of abnormal state in an absorption freezer and prevent trouble in advance by a method wherein it is diagnosed that a crystal to be caused by super-cooling of absorption liquid is going to be generated when its temperature is lower than a specified super-cooling crystal-forming temperature after its heat exchanging with absorption liquid having a high concentration. SOLUTION: Although a state point is normally at a position of higher temperature than a super-cooling crystal temperature Tc, this state point is moved lower than a crystal forming line in the case that an excessive temperature reduction is produced in absorption liquid (b) having a higher concentration through heat exchanging at a heat exchanger 13 so as to produce a super-cooled crystal. In this case, a temperature of the absorption liquid (b) having a higher concentration after cooling by the heat exchanger 13 is compared with a super-cooled crystal temperature Tc calculated in reference to an equation of Tc=-218.93+65.77×-0.4839× (X is a concentration of the absorption liquid (b)), thereby when a temperature of the absorption liquid (b) becomes lower than the super-cooling crystallization temperature, it is diagnosed that there is geared that a crystal may occur due to super-cooling in the absorption liquid (b). Accordingly, it is possible to prevent trouble or operation suspension from occurring.

摘要： PROBLEM TO BE SOLVED: To precisely perform a diagnosis for the qualitative deterioration of a rotor on a second-stage dry moisture-decreasing device without the use of a dew point meter. SOLUTION: In the regeneration area 11b of the chamber 12 of a rotor on a second stage dry moisture decreasing device, the temperature detecting part 14a of a temperature sensor 14 is arranged on the side close to a moisture decreasing area 11a on the outlet side of the regeneration area 11b, and the temperature detecting part 15a of a temperature sensor 15 is disposed on the side close to a purge area 11c. Thus it is possible to compare the temperature of a regeneration outlet measured by the two temperature sensors 14, 15 at the time of a normal rotor state to the temperature of a regeneration outlet at the time of a qualitative deterioration of the rotor and thereby, determine the degree of the qualitative deterioration of the rotor through diagnosis.

摘要： PURPOSE: To diagnose the degradation of a rotor continuously and forecast time for the replacement of the rotor by measuring the outlet temperature of regenerated air in a second-stage dehumidifier, and diagnosing the degradation of the rotor on a first-stage dehumidifier. CONSTITUTION: Air to be treated is dehumidified to a specified humidity by a precooler 7, and then the air is dehumidified by a first-stage dehumidifier. Further, the air is fed to a second-stage dehumidifier 2 with air fed back from a dry room 3 using a fan 8, and is additionally dehumidified. The obtained air having an ultra-low dew point is supplied to the dry room 3 after passing through an after cooler 10. In this case, the inlet temperature A and inlet humidity B of the treated air and the inlet temperature C of a regenerated air in the first-stage dehumidifier 1 and the inlet temperature D of the regenerated air and the outlet temperature E of the second-stage dehumidifier 2 are measured respectively. The degradation of a rotor 12 on the first-stage dehumidifier 1 is continuously diagnosed based on the measurement readings of the outlet temperature E of the second-stage dehumidifier 2.

摘要： PROBLEM TO BE SOLVED: To improve the estimating accuracy of the remaining service life of rotary equipment. SOLUTION: In a system which diagnoses the bearing section 2 of rotary equipment 1 by utilizing sounds produced from the bearing section 2, a directional microphone 3 is provided on a carrying device 4. An irregular waveform is caught within a prescribed period of monitoring time by converting the sounds measured by means of the microphone 3 into digital signals by means of a collecting and recording device 6 performing frequency analysis by means of a high-speed converter 7 using a wavelet function, and then, reversely moving the time base to the past. The nonlinear phenomenon which is caused by the collision of the flaws of the bearing of the section 2 is analyzed. A personal computer 8 discriminates the normal/abnormal state of the section 2 by comparing the amplitude value and threshold of the irregular waveform and estimates the remaining service life of the section 2 until the section 2 reaches a breaking value based on the increasing tendency of the amplitude value.
