Zaradi rastočih stroškov porabe električne energije je iskanju optimalnega upravljanja hladilne tehnike v nakupovalnih središčih v zadnjem času posvečeno veliko pozornosti. Celostno rešitev predstavlja združitev več nakupovalnih središč v zaključeno celoto, vodeno z nadzornega sistema, znotraj katerega se glede na definirane strategije vršijo optimizacijski algoritmi. V magistrskem delu so definirane, ocenjene in na primeru obstoječih nakupovalnih središč ovrednotene strategije za optimizacijo stroškov porabe električne energije hladilne tehnike. Temeljijo na analizi energijske porabe, upoštevajoč lastne in pridobljene meritve. Izvedena je primerjava obračuna električne energije po enotni in dvojni tarifi. Ocenjeno je 30,2 % znižanje v porabi električne energije hladilne tehnike. V primeru dvotarifnega obračuna je predvsem zaradi omogočenega časovnega zamikanja delovanja kompresorjev, za katero je izdelan optimizacijski algoritem, doseženih dodatnih 6,9 % prihrankov v denarju.

• Title: Strategies for optimization of electric energy consumption costs of refrigeration technique in shopping centers

Abstract

Due to the increasing costs associated with electric energy consumption major concern has lately been paid to ensure optimal refrigeration technique operation in shopping centers. An integral solution is accomplished by connecting numerous shopping centers into a completed whole controlled by a central system where optimization algorithms are run based on the defined strategies. This thesis defines and evaluates strategies for optimization of electric energy consumption costs of refrigeration technique. The strategies are based on the analysis of electric energy consumption regarding the measurements performed and obtained from existing shopping centers. Comparison between flat rate and time-based pricing is included. A 30,2 % decrease in electric energy consumption of refrigeration technique is achieved. In case of time-based pricing additional 6,9 % money is saved, mostly because of the enabled compressor operation time shifting for which an optimization algorithm is built.
