Kurzfassung englisch:
In this paper, we propose methods of handling,
analyzing, and profiling monitoring data of energy systems
using their thermal coefficient of performance seen in uneven
segmentations in their time series databases. Aside from
assessing the performance of chillers using this parameter,
we dealt with pinpointing different trends that this para-
meter undergoes through while the systems operate. From
these results, we identified and cross-validated with domain
experts outlier behavior which were ultimately identified as
faulty operation of the chiller. Finally, we establish correla-
tions of the parameter with the other independent variables
across the different circuits of the machine with or without
the observed faulty behavior.
