Optimizing Chiller Plant Control Logic

At Festival Walk, a large commercial complex in Hong Kong, the decision was made to change the control logic of the chiller plant to enhance the plant’s overall efficiency. The method implemented there can resolve some common problems encountered in decoupled systems. It can be adopted easily in existing buildings with similar problems and has a virtually zero investment. In-depth knowledge of the operating characteristics of the plant was gained using a comprehensive and stringent measurement and verification process. This project demonstrates the value of knowledge based operation management, where emphasis is placed on information and professional knowledge.
