This paper describes the analysis effort and resultant primary flow control strategy for an intensely interconnected chilled water distribution system that is fed by production plants at opposing ends. A brief description of the evolution of the existing campus chilled water distribution systems at the University of Arizona is followed by a statement of a problem common to many expanding chilled water distribution systems. This problem relates to the optimal control of dissimilar yet interconnected pumping and production plants. A simple hydraulic modeling spreadsheet with coupled graphical representation developed for the UA system is presented. The surprisingly simple control strategies designed for the UA system will be explained. The use of the simplified modeling approach as a long range production and distribution system planning tool will be explored. Conclusions on the applicability of the simplified approach and the extension of the UA distribution system control strategies to other district chilled water systems will be drawn.
