Methodologies for optimal control of chilled water systems without storage

In this paper, two methodologies are presented for determining the optimal control settings for chilled water systems that do not have significant thermal storage. A component-based nonlinear optimization algorithm was developed as a simulation tool for investigating optimal system performance. Results of this algorithm, implemented in a computer program, led to the development of a simpler system-based methodology for near-optimal control that is simple enough for on-line implementation
