Sequence management for chiller plants
When it comes to chilled water plant optimization, the control strategy based on management of individual water chillers is not an optimum approach to achieve the best results in terms of energy efficiency.
Individual control of the water chillers with common pipework will cause unnecessary cycling of compressors and associated excessive power consumption as a response to changes in cooling demand; consequently, compressor cycling will lead to unstable return water temperature and increased wear of compressors.
