摘要：

In this study, we derived an operating profile that minimizes startup time using a rigorous physical model that takes into account the characteristics of the compressors and heat exchangers that make up a centrifugal chiller, as well as the phase change and flow of the refrigerant. As an optimization method, we used the direct method of transforming the original infinite optimal control problem into a finite-dimensional nonlinear programming problem. We were able to derive an operation profile that reduces the startup time while satisfying the constraints compared to conventional operations and confirmed that the model and optimization method are effective for optimal design of equipment and control logic.
