Assessing chilled water system retrofit through data-log-based simulation

Cheng Chang, Qingpeng Wei, Xin Wang

Abstract: Many experts suggest that the current primarysecondary chilled water system can be converted to variable primary flow system for better energy performance. However, not every system can benefit from this conversion. Quantitative simulation analysis is in need before making the decision. This paper therefore presents a quick and easy modeling method for chillers and chilled water system based on common data logs stored in building management system. This modeling method can help predict the feasibility as well as energy-saving potential of the configuration conversion. An application of this method has been taken in a large-scale shopping centre.
