Model-Based Diagnosis of Telecommunication Cooling Systems Malfunctioning

چکیده
A model is developed that allows simulating the most-likely failures possibly occurring in freecooling (FC) systems of telecommunication (TLC) switching rooms. Main aim to provide an effective and online implementable diagnosis method, which turn will allow fulfilling threefold function safeguarding electronic equipment, ensuring desired air quality case human presence reducing malfunction-related waste energy. Specifically this work, obstruction (reduction volumetric flow introduced into room) loss efficiency (degradation fan) are deepened. Two black-box sub-models were simulate above described faulty functioning free-coolers. Subsequently, fault signature matrix was developed, through “symptoms”, calculated as residuals between “faulty” “non faulty” conditions monitored variables, associated corresponding faults. The peculiarity sector, where nowadays data acquisition monitoring platforms significantly spreading monitor most significant energy consumptions, including cooling loads, proved essential guaranteeing isolation different simulation results highlight reliability diagnostic tool, expected be versatile easy implement enough for being extended air-handling unit diagnosis, well other industrial sectors.

Diagnosis of Heat Exchanger Scales in Cooling Water Systems
An experimental database is compiled in order to fingerprint the scales formed over the hot surfaces of heat exchangers, in cooling water systems or other systems with similar chemistry. To collect these data, a dynamic simulating pilot plant was designed with considerable application flexibility among which simultaneous flow of water with different velocity and heat fluxes to three simulat...

متن کاملOnline Model-Based Diagnosis of Production Systems
This paper extends model-based diagnosis (MBD) (Reiter 1987; de Kleer & Williams 1987) to systems which convert, move and process material. Examples of such systems are printers, refineries and food processing plants. Such plants present two challenges to model-based diagnosis: (1) the plant may process 100s-1000s of items per minute so retaining full details of behavior of all past objects is ...
متن کاملGraph-Based Structural Analysis for Telecommunication Systems
Many methods and tools for the reengineering of software systems have been developed so far. However, the domain-specific requirements of telecommunication systems have not been addressed sufficiently. The E-CARES project is dedicated to reverse engineering of complex legacy telecommunication systems by providing graph-based tools. With E-CARES, the software architecture of a telecommunication ...
