S600 building automation system based on fault diagnosis dehumidifier

Systems listed in Table 2 can be implemented fault diagnosis. 5 Conclusion (1) In this paper, building automation system, based on the design and construction of the dehumidifier fault monitoring and diagnosis system, and rule-based fault diagnosis dehumidifier. (2) The $ 600 PPCL language features simple and complex fault diagnosis method is not easy to use PPCL programming, which has become $ 600 system fault diagnosis system bottlenecks,[link widoczny dla zalogowanych], whether to use a separate fault diagnostics of complex models is the next step to consider problems.

Ultrasonic atomization air conditioning drip ring to eliminate the new Technology for ultrasonic atomization technology is the use of electronic ultra-high frequency vibration theory, pass on the ultrasonic generator in a certain frequency of oscillation current, high frequency power signal through the transducer converts the ultrasonic mechanical vibration, thereby enabling high frequency resonant film atomization, the water absorption of this energy after the formation of mist at room temperature. Droplet diameter in the # ,[link widoczny dla zalogowanych],1-1om level, a lot of mist in the air with negative ions, can increase the air humidity and fresh air, and the effective absorption of nicotine in the air, formaldehyde and other harmful substances. Is currently using more films for the ultrasonic atomizing piezoelectric ceramics. The atomization mechanism is as follows: for the thickness of the ultrasonic signal transmitted to the vibration of the piezoelectric ceramic transducer, the mechanical vibration transducer to pass the liquid,[link widoczny dla zalogowanych], so that the liquid produced uplift, and uplift of the occurrence of cavitation around, by this cavitation impulse waves generated by the transducer will be constantly repeated vibration frequency, so that the liquid level to generate finite amplitude capillary waves. Fluctuations in the waves flying so that the liquid spray, thereby eliminating the dripping air conditioner. Than the traditional mechanical or rely on evaporation to remove the air conditioning is much superior to drip method. (From 2006,
