Energy saving potential on centrifugal water chillers with frequency converter system: a case study in china

摘要

In order to evaluate the energy saving potential during centrifugal water chillers' operation, centrifugal water chillers from an industrial enterprise in China are investigated. Based on the actual operation data gained from 3 different water chillers, their working performances and the energy consumption situations are reported and researched in this paper. Meanwhile, the energy saving potential and economic performance of the chillers are also reported and analyzed, when the appropriate variable frequency systems are introduced.
