Summary: | 碩士 === 國立臺灣大學 === 化學工程學研究所 === 99 === This work aims to develop a mathematical model for the synthesis of
refrigerated water network systems and chiller operating strategy simultaneously.
First of all, we proposed one model which includes all possible configurations of
refrigerated water network system under all conditions.
By setting relevant constraints up for each part of the
superstructure, the design problem of refrigerated water
network system is formulated as a mixed-integer nonlinear
program that can be solved for optimal configuration of
refrigerated water network.
Objective functions 1 and 2 are considered which
involving the mimnimization of refrigerated water supply and
obtaining a unique network structure.
Furthermore we also proposed a superstructure for chillers'' operation, considering
different operating upper and lower bounds. In this work, two objective functions
are considered to minimize fixed and variable operating cost.
Finally, numerical examples are used to show that the proposed approach can provide
the optimal design of refrigerated water network system and chiller operating strategy.
